Goldschmidt in Heidelberg. OO: XXXIV. 1 м. ao in NM då D i A 5 » + An den Albit knüpft sich eine Reihe interessanter Fragen. Er ist einer der wichtigsten Vertreter des unter den Mineralien seltenen triklinen Systems. Er bildet das eine Endglied der Reihe der Kalk-Natron-Feldspäthe, die in der Krystallographie, ebenso wie in der Petrographie eine wichtige Rolle spielen. Anderseits besteht eine enge Beziehung zwischen dem triklinen Albit und dem monoklinen Orthoklas, die man bei den Fragen über das Wesen der Isomorphie zu berücksichtigen hat. Ferner ist der Albit ausgezeichnet durch Zwillings- und Viellingsbildungen, auch damit verbundenen Ablenkungen und Winkelschwankungen, Krümmungen und Facettenbildungen, die Gegenstand des genetischen Interesses sind. Er zeigt regel- mässige Verwachsung mit dem Orthoklas, der einem andern Krystallsystem angehört. Er ist häufig und weit verbreitet und seit Jahrzehnten immer aufs Neue Gegenstand des vielseitigen Studiums. Es vergeht kein Jahr, das nicht Beobachtungen über den Albit brächte. Trotz der Häufigkeit des Albits sind Krystalle, die sich zur Messung eignen, selten. Die genaue Berechnung der krystallographischen Elemente stösst beim Albit auf besondere Schwierigkeiten, herrührend von gestôrter Flächenausbildung. Diese Störungen dürften wesentlich hervorgebracht sein durch die erkennbare, wie ver- steckte Viellingsbildung nach dem Albitgesetz'). Auch isomorphe 1) Vgl. Zeitschr. Kryst. 1898. 29. 381. Index. 1890. 2. 22. iP Einlagerungen wirken störend da, wo der Albit nicht rein d.h. nicht das Grenzglied der Albit-Anorthit-Reihe ist. In dem Index der Krystallformen wurde der Versuch gemacht (1890. 2. 19—22), zuverlässige Elemente zu erhalten. Dies geschah auf Grund der Messungen von Max Schuster, eines äusserst zuverlässigen Beobachters, der sich gerade damals eingehend mit dem Albit befasste. Schuster hatte, um den Einfluss der Zwillingsbildung zu beseitigen, durch Abspalten solche Partien hergestellt, an denen dem Augenschein nach Zwillingsbildung nicht zu finden war. Die auf Grund von Schusters Messungen gewonnenen Elemente weichen von denen der andern Autoren stark ab. Als daher bei Ausarbeitung der Winkeltabellen!) die Frage ent- stand, welche Elemente zu acceptieren seien, wurde die Tabelle für die Schusterschen Elemente ausgerechnet und daneben für die von Brezina?) angegebenen. Spätere eigene Messungen am Albit liessen die Überzeugung gewinnen, dass die Schusterschen Elemente nicht haltbar seien, und es entstand der Wunsch, durch genaue Messungen und Discussion die Frage abzuklären. Indessen erschien eine schöne Publication von G. Melczer?) «Daten zur genauern Kenntnis des Albits», die das Bekannte zusammenfasste und neue sorgfältige Beobachtungen und Be- rechnungen zufügte. Für Melezers Beobachtungen bot sich ausgezeichnetes Material von Nadabula, in scharfer Ausbil- dung und chemisch von idealer Reinheit. Melczer gibt folgende Zusammenstellung derjenigen Ele- mentangaben, die er für die zuverlässigsten hält: 1) Berlin. Springer. 1897. 139 u. 140. ?) Min. Mitth. 1873. 3. 19.

Goldschmidt 0.6373:1:0.5599 94°18' 116°41' 87°37' Aus dieser Zusammenstellung geht hervor, dass starke Differenzen nicht mehr bestehen, die Elemente des Albit mit grosser Annäherung sicher gestellt sind. Das Mittel aus allen mit Ausschluss der unsicheren ergibt: NÅ TA RE RES ER 0.6349 :1: 0.5578, 94°09! 116°35' 8757 Dreyer u. Goldsehmidt.... 0.6373: 1:0.5599 94°18’ 116°41' 87°37’ Die Differenz ist am stärksten beim Winkel 7. Da beträgt sie 20’. Dies ist nicht auffallend, da die grösste Unsicherheit in den Winkeln der Prismenzone besteht. => Unsere Elemente stimmen sehr nahe mit den von Brezina berechneten, für die die Winkeltabelle ausgerechnet wurde. Trotz der geringen Differenz erschien es wünschenswert, für die verbesserten Elemente die Winkeltabelle neu zu berechnen wegen der grossen Zahl der hinzugetretenen neuen Formen. Zur Neubestimmung der Elemente bot sich eine günstige Gelegenheit. Dr. G. Lincio brachte von einer Reise nach Kopenhagen die Nachricht, es befinde sich im dortigen Museum ein grosser Vorrat ausgezeichneter Albite von Grön- land. Er hat selbst eines dieser Kryställchen gemessen. Die Ausbildung ist eine für Albit selten scharfe; auch zeigten die Analysen von Chr. Winther (durch Prof. N. V. Ussing freundlichst mitgeteilt), dass ein reiner Albit vorliegt. Die Analysen von Chr. Winther ergaben folgende Zahlen: Albitv. Kangerdluarsuk Albit v.

V. Ussing in Kopenhagen wurde uns das ganze dort befindliche, dem mineralogischen Museum der Uni- versität gehörige schöne Material zum Zwecke krystallographi- scher Bearbeitung zur Verfügung gestellt, wofür wir zu grossem Dank verpflichtet sind. Das Material stammt grösstentheils von den dänischen wissenschaftlichen Expeditionen her, die von der «Gommission für die Leitung der geologischen und geographi- schen Untersuchungen in Grönland» ausgesandt wurden (Expe- ditionen von Bloch 1890, Flink 1897, Steenstrup 1899 und Ussing 1900); einige der untersuchten Krystalle sind während der letzten Jahre von Grönländern gesammelt und an das Kopenhagener Museum verkauft worden. Die Resultate der Untersuchung mögen im Folgenden mitgeteilt werden. +] Besonders folgende Grunde waren ausserdem massgebend zum Eingehen in die Untersuchung: 1. Die neuen zweikreisigen Goniometer mit ihrer verbesserten Optik, mit Wechselsignal, vermehrter Lichtstårke und Okular-Abblendung machten es måglich, kleine und lichtschwache Flåchen aufzufinden und zu symbolisieren, die sich bisher der Erkennung entzogen hatten. So war die Möglichkeit gegeben, manches Neue zu finden. Diese Hoffnung hat sich erfüllt. Unsere Kenntnis des Formensystems des Albils hat sich wesent- lich erweitert. 2. Die in der Publication von Borgstrém und Gold- schmidt «Krystallberechnung im triklinen System, illustriert am Anorthit» (Zeitschr. Kryst. 1905. 41. 63) ausgearbeitete Me- thode der Elementberechnung ermåglicht auch fir das trikline System die Elemente nicht aus fünf ausgewählten Fundamental- winkeln zu berechnen, sondern zu dieser Berechnung alle guten Positionen aller gemessenen Krystalle zugleich in die Rechnung zu ziehen und unter sich auszugleichen. Diese Methode sollte angewandt werden. Kritik und Ubersicht beim Ausgleich gestattete das Schwan- kende zu eliminieren und so das Zuverlåssigste allein der defi- nitiven Rechnung zuzuführen. Nicht immer sind die best aus- gebildeten Flåchen am richtigsten Ort. So sind beim Albit die Prismenflächen mit dem Pinakoid M = 0 & (010), wenn noch so scharf und gut reflektierend, doch abgelenkt und unzuverlåssig. Die Untersuchung hat das bestätigt, was G. Melczer!) vom Albit von Nadabula sagt: «Ein erschwerender Umstand war ferner, dass ich die zu M gemes- senen Winkel ausser Acht lassen musste, weil ich mich gleich bei der Mes- sung der ersten Krystalle überzeugte, dass dieselben, auch wenn sie gute, einfache Reflexe geben, gegen die Prismenflachen convergieren. Sie liegen nämlich nicht genau in den Zonen nP, ox, yy und, wo beide Flachen (010 bis 1° kleiner als 180°». 12 | — und 010) gut ausgebildet sind, ist der Winkel um 1) Zeitschr. Kryst. 1905. 40. 484. 8 3. Diese Störung gerade in der Prismenzone ist genetisch von wesentlicher Bedeutung. Sie erklart sich durch Ablenkung und schiefe Verwachsung infolge der Viellingsbildung nach dem Albitgesetz '). Merkwiirdig ist dabei, aber durchaus sicher gestellt, dass die Ablenkung die Terminalflachen nicht oder doch nicht so stark trifft, als die Prismen. Es entsteht die Aufgabe, die Ur- sachen dieses Gegensatzes klarzulegen. Zur Lösung dieser Aufgabe konnten die vorliegenden Untersuchungen beitragen durch Feststellung der Tatsachen. 4. Von den für Albit angegebenen Formen ist eine An- zahl unsicher. Es erschien wünschenswert, das Verzeichnis zu klären durch Bestätigung oder Ausscheidung des Unsicheren. Durch die Messungen am grönländer Albit wurden in der Tat einige Formen gesichert, die der Bestätigung bedurften. Andere schienen nach wie vor unsicher. Zur Prüfung der inneren Wahrscheinlichkeit der zweifelhaften Formen wurde die Dis- cussion der Zahlenreihen?) herangezogen. Literatur.

Er berichtet weiter über Albit-Funde sowohl von Kangerdluarsuk als von Siorarsuit und Tutup Agdlerkofia am Tunugdliarfik Fjord. Diese Fundorte mit Ausnahme des letzteren haben Material geliefert, das der vorliegenden Arbeit zugrunde liegt: Beobachtete Formen. Am Goniometer durchgemessen wurden 17 Krystalle.

Er bemerkt aber dazu: «Die Flache lieferte kein ganz vollkommenes Spiegelbild, und ich bin geneigt, sie als die Resultante eines sehr feinfurchigen Wechsels der beiden anliegenden Flächen P'(o) und «P'(7’) anzusehen». Mit Rücksicht auf ihre innere Wahrscheinlichkeit darf die Form wohl doch als gesichert gelten. 14 g = 23 (221) findet sich bei Lévy (Descript. 1837.

Die Form bedurfte der Bestätigung, da sie nur an einem Periklin beschrieben wurde, bevor das Periklin-Zwillings- gesetz bekannt war.

Die auffallende Tat- sache, dass wir beim Albit in der Literatur so viele unsi- chere Formen neben verhältnismässig wenig sichern antreffen, erklärt sich folgendermassen. Die reichliche, selten fehlende Viellingsbildung (Compositbildung !}), verbunden mit Ablenknng und schiefer Ver- wachsung bewirkt eine Unsicherheit der Flächenposition. Diese Unsicherheit trifft besonders die Hauptzonen, vor allem die Prismenzone. Hier begegnen wir fortlaufenden Reihen von Reflexen, die man nicht deuten kann, ohne den Krystall in alle seine Lamellen aufzulösen, dann Positionsschwankungen durch Ablenkung nnd Ausheilung einspringender Winkel. Trotzdem (man kann auch sagen weil) hier genetisch das Manichfaltigste vorgeht, kommen nur die einfachsten Formen der Reihe zur sicheren Bestimmung als typische Formen. Alles andere bleibt unsicher oder ist vicinal und influenziert. Kommen nun solche vicinale Gebilde in die Nähe eines typischen Ortes, so ist selbst der erfahrene und kritische Beob- achter geneigt, solchen Gebilden ein Symbol zu geben, sie als typisch anzusehen. Wie viel mehr der minder Erfahrene, der in jedem Reflex neuer Position eine neue zu symbolisierende Form begrüsst. Ähnlich wie in der Prismenzone ist es in den übrigen Zonen, von denen nur wenige genetisch wichtig sind. Die wichtigste von diesen ist [eM], dann [PM], [Pl], [РТ]. !) Ueber Composite vgl. Zeitschr. f. Kryst. 1907. 43. 347. XXXIV. 9 18 Das Gesamtbild ist: Wenige Zonen mit vielen schwankenden, wenig typischen Positionen. Das ist das Bild einer Formen- entwicklung wie sie die Compositbildung') zu begleiten pflegt. Schwierigkeit der Bestimmung und Deutung hängt mit diesen Verhältnissen zusammen. Es ist oft nicht leicht, die Zwillingsteile richtig zu trennen, für jede Fläche —, oben und unten zu unterscheiden. besonders dann, wenn Viellings- oder Zwillingsbildung nach zwei Gesetzen zugleich vorliegt oder die Unterlage (Orthoklas) bestimmend und ablenkend auf die Flä- chenlage mitwirkt (Induction und Influenzirung?)). Letzteres ist beim Albit häufig der Fall. Hier hat die zweikreisige Messung mit ihrer graphischen Discussion im gnomonischen Bild uns in den Stand gesetzt, die kritische Auflösung komplizierter Bil- dungen durchzuführen und dadurch eine Anzahl neuer Formen sicher festzustellen, unsichere zu beseitigen. Aber auch diese klärende Bearbeitung ändert das Gesamt- bild nicht: Wenige Zonen, mit vielen schwankenden, wenig typischen Positionen. Die Ausscheidung des Unsicheren ist beim Albit mehr als bei andern Krystallarten nötig, da die Aufnahme des Unsicheren bei Deutung der an sich schon complicierten Verhältnisse ver- wirrend wirkt. Ist ein Symbol, wenn auch unsicher, angegeben, so verleitet dies einen folgenden Beobachter, einen Reflex ähn- icher Position ebenso zu deuten, ohne die strenge Kritik anzu- wenden, die eine neue Form erfordert. So erfährt die unsi- chere, oft unrichtige Form, eine scheinbare, unberechtigte Bestätigung. Es empfiehlt sich, alle unsicheren Formen bis zur sicheren Neufindung bei allen Diskussionen als unrichtig oder nicht vor- handen anzusehen und sie nur in den Verzeichnissen zu führen, um die Angaben des Beobachters zu respectieren und sie andern, vielleicht anders Urteilenden, nicht vorzuenthalten. !)

Es sind zünächst die Positionswinkel фо für alle guten Flächen jedes Krystalls zu berechnen aus den Ablesungen v und A, wobei o=v—v; p=h—h. Die Grösse hy, die Polstellung des Instruments, ist leicht ermittelt. Sie wurde für unsere Messungen — 50° gemacht. Die Richtigkeit der Werte о hängt nun ab von einem guten = und vorsichtigen Polarstellen des Krystalls am Goniometer. 1) Zeitschr. Kryst. 1905. 41. 63. 29 Diese bot keine Schwierigkeit infolge der jedesmal guten Aus- bildung der Prismenzone als Zone. Der Ort der Prismen schwankte, aber nur innerhalb der Zone. Selten fiel ein Reflex aus der Zone heraus. So erscheinen für alle Messungen guter Flächen die Werte o gesichert. Anders ist es mit den g. Sind die © richtig abgelesen, so brauchen wir zur Berechnung der g für jeden Krystall eine ausgleichende Berechnung von v,. Dieser Berechnung von v, ist eine ganz besondere Sorgfall zuzuwenden. Geschieht sie unvorsichtig, so sind alle © ungenau. Der Albit bietet hierfür eine besondere Schwierigkeit durch den Umstand, dass die Flächen der Prismenzone wegen Schwankens hierzu nicht zu brauchen sind. Speziell das hierfür so wichtige und bequeme, stets vorhandene und meist gross und eben ausgebildete М = 0х versagt, da die Erfahrung zeigt, dass es aus den Zonen, denen es angehört, innerhalb der Prismenzone abgelenkt ist. Diese Ablenkung schwankt nach beiden Seiten d.h. nach T und Г hin von 10’ bis über 1°. Im Durchschnitt beträgt sie etwa 20’. Auch die Prismen 7'/fz sind innerhalb der Prismen- zone abgelenkt und schwankend, wenn auch ihre Reflexe noch so gut sind. Es bleibt daher nur übrig, ©, mit Hilfe der Zonen der Terminalflächen zu berechnen und zwar ausschliesslich aus den Quer-Parallelzonen Og und 19. Nur ausnahensweise konnte einmal die Zone 24 herangezogen werden. Die Berechnung von +, aus den Quer-Paralielzonen geschah aus je zwei Flächen p,q, und 9,9, mit den Ablesungen 0,9, und v,o, nach der Formel: v v Lo — 44 m v?

Hierbei fällt jede Fläche beider Stellungen in die gleiche Quer- Ай Paz Text Fig. 1. parallelzone, also Og wieder in Zone Og, 14 wieder in Zone 1g. Dies erfolgt mit grosser Strenge. Es kann also jede Fläche einer solchen Zone mit in die Rechnung gezogen werden, gleichgiltig, ob sie der ersten oder der zweiten Stellung ange- hört. Ausgenommen ist nur die stets abgelenkte Grenzfläche der Reihe M = 0%. Anmerkung. Es bewährte sich bei unseren Krystallen regelmässig die Tatsache, dass bei den Viellingen nach dem = = 1 Albitgesetz die Querparallelzonen Og und 1g, auch 29 und All beider Stellung sich deckten und zwar obne Ablenkung bis auf M, das aus der Zone gerückt ist, dass ebenso die Prismen- zonen sich deckten, jedoch mit Ablenkung aller Flachen inner- halb der Zone. Diese Tatsachen sind von wesentlichster Bedeutung für die Beurteilung der Vorgänge bei der Zwillingsbildung. Es sind nicht die ganzen Partikel an der Zwillingsgrenze gegeneinander abgelenkt, wie wir das beispielsweise beim Ge- russit von Mapimi') und von Monteponi°) kennen gelernt haben. Es sind vielmehr für die einzelnen Partikel gewisse Vor- zugsrichtungen (Flächennormalen) in der Kraftsphäre gegen andere abgelenkt, aie ihre Richtung beibehalten haben. In der Prismenzone sind alle Richtungen abgelenkt, in den übrigen Zonen nicht. Es entsteht die Frage, warum gerade in der Prismenzone? 1) Gdt. Jahrb. Min. 1902. Beit bd. 15. 582. ?) Hubrecht Zeitschr. Kryst. 1905. 40. 170. 31 Es entsteht ferner die genetisch wichtige Frage: was sind bei den Zwillingen nach dem Albitgesetz die Verknüpfer, die Binder? Gewiss sind es die Bindezonen [29]; [Og] und [19] als Ganzes. Ist nun in diesen der Hauptbinder die allen diesen Zonen gemeinsame Fläche M = 0» resp. deren Normale oder sind es zugleich die sich fast genau deckenden ebenfalls gestörten Prismenflächen 7'/ (f2). Ist etwa gerade die Ablenkung charakteristisch für die aktiven Binder, die gleichzeitig tätig sind und widersprechende Anforderungen stellen? Ist gerade die Prismenzone dadurch als Zone fest, für die Einzelpositionen gestört, weil in ihr die aktiven Binder MT! liegen? Sind dagegen in den Zonen Og und 19 die Normalen der Flächen Р = 0, е = 02, и = 02 гезр. х = 10, о —1, р —11 nicht aktive Binder und deshalb nicht abgelenkt? Kann gerade die Störung als Kennzeichen für die Activitat der Flächennormalen als Binder angesehen worden ? Ist etwa die grosse Nähe der Binder in der Prismenzone an der Ablenkung schuld, während bei etwas grösserer Distanz der Punkte eine Ablenkung nicht stattfindet? Die vorliegende Untersuchung liefert Material zur Prüfung und endlichen Entscheidung dieser für die Krystallgenese wie für die Formenentwicklung wichtigen Fragen. Die eingehende Untersuchung der Fragen soll an anderem Ort geschehen. Berechnung von &,. Schema und Beispiel.

Diese differieren stark von allen andern Werten und sind am besten aus der Rechnung fortzulassen. Wir stehen nun vor der Frage, ob wir für v, das Mittel aus den sehr guten Werten annehmen sollen, oder das Mittel aus allen unter Ausscheidung von p'o und o'p, oder endlich das Mittel aus allen. Im Zweifel stellen wir die drei Werte nebeneinander. 36 Mittel aus den 7 besten Werten...... ©, = 104°55' Mittel aus allen, ausser p'o und 0'p... - = 104 59 Mittel&austallent!s... rn Amine = tes 205005: Das Mittel aus den 7 besten Werten ist offenbar das rich- tigste, in Anbetracht der geringen Schwankungen.

Darin sind die sichersten Positionswinkel fett gedruckt, die mindest sichern in ( ). Anmerkung zu Tab. Ill. $. 36. 37. Für Bildung der Mittelwerte ist der mathematische Weg der, jedem Wert ein Gewicht beizulegen, das sich zusammensetzt aus der Zahl der Beobachtungen und einer für die Qualität eingesetzten Zahl. Der rationelle Weg dagegen ist der, auf grund alles Bekannten das Zuverlassigste auszuwahlen. Man wird den mathematischen Weg beachten, aber sich davor hüten, das Beste durch Heranziehen von Geringerem zu verderben. Wo die Grenzen sind zwischen strenger Rechnung und Entscheidung aus sonstiger Beurteilung der Verhaltnisse, darüber lassen sich Vorschriften nicht aufstellen. Die oberste Regel ist vernünftig verfahren, unter vor- sichtiger Erwägung aller Momente. In der Regel wurde folgendes Verfahren als das beste befunden: A. Bilduug des Mittels aus den besten Werten allein, B. Bildung des Mittels aus allen brauchbaren Werten. Vergleich von A und B. Sind beide gleich, so ist der beste Mittelwert gesichert. Differieren beide, so gibt die Differenz ein Anhalten, in welchen Grenzen A durch B zu modifizieren ist. In der Regel ist A ein grôsseres Gewicht beizulegen und sein Wert durch B nur wenig zu modifizieren. Auf diese Weise sind die Mittel- oder wahrscheinlichsten Werte in obiger Tabelle uud in den folgenden Rechnungen gebildet. Es liegt in diesem Ausgleichsverfahren etwas persönliche Willkür. Doch ist diese einer rigurosen aber ungerechten mathematischen Vorschrift vorzuziehen. Letztere lässt sich ja von persönlicher Willkür auch nur scheinbar freimachen. Es bleibt die Auswahl des Brauchbaren und das gegebene Gewicht noch immer willkürlich. Berechnung der Elemente der Projection: a’); %',: 2’, Sin »; D'o 605 >; 9’, aus den Positionswinkeln op.

Sie kehrte fast bei jedem von unseren Krystallen wieder und zeigte sich als eine der Hauptformen unserer grönländischen Fundorte. Es möge hervorgehoben werden, dass die Ablenkung in der Prismenzone auch hier bei dem einfachen Krystall gefun- den wurde. Es ist anzunehmen, dass versteckte Lamellen nach dem Albitgesetz auch dieses Kryställchen durchsetzen und an den Ablenkungen Schuld sind. Die Flächen M = 0% (010) sind beide vortrefflich aus- gebildet, der Reflex vorzüglich, und trotzdem sitzt er nicht an seinem Ort, differiert vielmehr um — 10’ resp. — 24’ von dem aus den Terminalflächen berechneten Ort. Fläche und Gegen- fläche sind nicht parallel. Die praktische Folge ist, dass man zum Zwecke einer genauen Ortsbestimmung des 0-Meridians (Berechnung von v,) die M-Flächen nicht verwenden kann, auch nicht die anderen Prismenflächen, wenn sie noch so gross, glatt und einheitlich reflektierend sind, sondern nur die Termi- nalflächen. Theoretisch sind diese Ablenkungen in der Prismenzone von höchstem Interesse. Sie finden sich bei allen von uns untersuchten Krystallen. Krystall 2 von Kangerdluarsuk (Taf. I Fig. 2).

Das Albit-Vorkommen von Grönland, speziell von den Fundorten Siorarsuit und Kangerdluarsuk hat sich als das formenreichste und vielleicht das best ausgebildete unter den untersuchten Albiten gezeigt. Es hat 32 verschie- dene, gut gesicherte Flächenarten geliefert, darunter 8 neue; 7 von früheren Beobachtern angegebene, aber der Bestätigung bedürftige Formen, wurden definitiv gesichert. Das Formenverzeichnis des Albit umfasst jetzt 37 sichere Formen (darunter 32 von Grönland) und 6 unsichere (darunter 2 von Grönland). 2. Die für den Albit angegebenen Formen wurden einer kritischen Sichtung unterzogen, wobei die Discussion der Zahlenreihen gute Dienste leistete. Neben den unrichtigen und vicinalen wurden auch die unsichern oder der Bestätigung Combinationen. * bedeutet: neu - bedeutet: bestätigt.

Die von Chr. Winther ausgeführte, uns zur Publika- tion überlassene Analyse hat gezeigt, dass das Material ein sehr reiner Albit ist. Auf einen solchen beziehen sich also unsere Elemente. 4. Die Elemente des Albit wurden neu berechnet unter Heranziehung aller besten Messungen der 16 ersten gemessenen Krystalle. Dabei wurde die von Borgström und Gold- schmidt veröffentlichte Methode der Krystallberechnung für das trikline System verwendet und den vorliegenden Verhält- nissen angepasst. Das ausführliche Beispiel der Ausrechnung dürfte manchem willkommen sein. Die so gefundenen Elemente dürften als die für Albit best gesicherten gelten können. Sie weichen nur um ein Geringes von den von Brezina nach Raths Messungen berechneten Elementen ab, dagegen stark von den nach Schusters Mes- sungen von Goldschmidt berechneten Elementen. Letztere können daher nicht mehr festgehalten werden. 5. Mit den neuen Elementen wurde eine Winkeltabelle neu berechnet. Dies geschah trotz der geringen Differenz wegen der vielen neuen Formen, sowie mit Rücksicht auf die sonstige Abklärung des Formenverzeichnisses. 6. Zur Berechnung der Elemente konnten nur die Ter- minalflächen verwendet werden. Die Flächen der Pris- menzone zeigten auch bei den schärfst ausgebildeten Kry- 60 stallen starke Ablenkungen. Das Studium dieser Ablen- kungen und ihrer Beziehung zur Zwillings- und Viellingsbildung ist genetisch von grossem Interesse. Speziell die Tatsache ist wichtig, das gerade die stärkste Zone am meisten gestört ist, ohne Störung des Krystallbaues und ohne Ablenkung der Ter- minalflächen. So sind die Flächen der Parallelzonen 09, 19, 2q schön an ihrem Ort, während das zu allen diesen Zonen gehörige M = 0% jedesmal, meist stark, abgelenkt ist. Correcturen.

On the occurrence of Fredericella sultana Blumenb. and Paludicella Ehrenbergii van Bened. in Greenland. By C. Wesenberg-Lund. 1907. XXXIV. 5 CE pt arth gt we FR Ps os | o's SS © eT ha. » у. ee la 3 4 oe I ve by + D bi} aS | 2 3 så * = . y i | Denmark has hitherto been the most northerly country from which fairly detailed reports of the fresh-water Bryozoa have appeared. From Dalyells’ (1848 р. 87) and Allmans’ researches (1856 р. 78) we know that Cristatella mucedo and Plumatella fungosa occur in Scotland, and that P. repens has probably a wide distribution in that country. As regards Norway Kraepelin only reports (1887 p. 99) that he has taken Paludi- cella in the neighbourhood of Kongsberg and Plumatella fruticosa (1887 p.120) near Drammen. To my knowledge we have hardly any reports at all from Sweden whereas a good many from Finland. From Nurmijärwisö са. 6 miles to the north of Helsingfors Paludicella, Fredericella, Plumatella princeps, var. fruticosa, P. polymorpha var. repens and cespitosa besides Cristatella have been reported by Stenroos (1898 р. 50). As far as I am aware no growing Bryozoa have been found farther north.” From the existing evidence as to the boundaries of the fresh-water Bryozoa it would seem that they do not extend very far to the north; their geografical distribution would seem to justify our con- sidering them as organisms requiring a considerably high summer temperature to enable them to thrive. Yet several circumstances make it questionable whether this opinion will hold good. In the first. place it has been proved that fresh-water Bryozoa occur at considerable depths where the annual temperature is but low. Du Plessis thus pointed out a species of Frede- ricella, by Forel termed К. Du Plessisi (1901 р. 113). It is common in the upper part of the abyssal region at ca. 45 m. where Forel obtained ca. 150 specimens at a single dredging. * 5 64 At this depth they live and thrive at a temperature varying between 4—9° С. Zschokke recently (1906 p.72) states that the Vierwaldstätter See down to its greatest depths is covered with “Rasen und Wäldern” of Fredericella Du Plessisi, in other words that even at depths of 214 m. (Halbfass 1903 p. 712) with a constant annual temperature of ca. 4—5° C. (Am- berg 1904 p. 91—93) the fresh-water Bryozoa still occur’). These curious deepwater Fredericella which I have also dredged in Lake Geneva are not as is the case with Bryozoa in general attached to other bodies, but like the Pennatulides they stick loosely in the mud of the lake bottom. According to Forel they have the power of moving and when kept in glass vessels are said to be able to rise out of the mud at the bottom and at will to fasten themselves in the same. Da- venport mentions (1904 р. 213) that Paludicella Ehrenbergi and Fredericella sultana have been determined in catches from Lake Michigan at depths of 23—36 m. For my own part I have often during several years taken shells of mussels at 11 —15 m. with fixed statoblasts of Plumatella attached to them and besides at one dredging in Furesø, estimated at 20 m., I got a colony of Cristatella. Further, it has been established that fresh-water Bryozoa inhabit lakes almost verging on the snow region. The species which according to Zschokke (1900 p. 115) occur in mountain lakes are Fredericella sultana, Plumatella repens and Cristalla mucedo, of which Cristatella has been found at the greatest height (2293 m.). From lakes in the Engadin valley at 1825 m. above sea level Zschokke reports Fredericella as occuring abundantly even below the icecover of the lakes. Besides these examples furnished by the fauna of our own day we may also point to the Bryozoa of past epochs for evidence which unmistakably shows that these organisms 1) The same species has quite recently also been found in the abyssal region of lake d'Annecy (Marc le Roux 1907 р. 267). 65 must be quite able to exist at a much lower temperature than our present knowledge of their geographical distribution would seem to warrant. In samples of chitin and silicious fragments from Scandinavian peat bogs kindly sent me some years ago by Gunnar Anderson | was able (1896 р. 51) to determine Cristatella statoblasts so early as in the Dryas-layers; Pluma- tella did not occur until the pine period. Since then Crista- tella as well as Plumatella statoblasts have been reported by several observers as well as by myself in the quartar layers of Denmark, Sweden, Norway, Finland and North Germany. As I thought it unnecessary to mention here the numerous places of discovry, I applied to the intimate connoisseur of the fauna and flora of the Danish peat-bogs, N. Hartz, for some general information as to the occurrence of Bryozoa statoblasts in our peat-layers. According to Hartz the statoblasts of the above- mentioned Bryozoa are found throughout all the several layers, the Cristatella occurring most commonly, whereas in the Dryas- layers the Plumatella are more rare. Consequently it cannot be denied that, whether we con- sider the occurrence of the fresh-water Bryozoa of the present time or call to mind their vertical distribution during past ages, in both cases it seems extraordinary that now-a-days the Bry- ozoa should cease at so great a distance from the polar circle as has hitherto been supposed to be the case. If these orga- nisms have been able to exist under the natural-conditions of the Dryas-period and if still able to liwe at the low tempera- tures prevailing at the bottom of the Vierwaldstattersee as also in Alpine lakes situated near the snow-region, we should be justified in supposing that, although the natural conditions ob- taining in countris beyond the arctic circle at the present day do not admit of a direct comparison with the conditions pre- vailing at the period where the Dryas layers were deposited in our own latitudes, that the northern limit of these forms at present would extend farther to the north. 66 Mr. Ad. Jensen of the Zoological Museum of Copenhagen on his return from Greenland in the autumn of 1906 informed me that he had found freshwater Bryozoa in the vicinity of the colony of Jacobshavn near the Disko-Bay (69° 13’ N.). Being conversant with the above facts this message was of course full of interest to me and ! owe Mr. Ad. Jensen my best thanks for the readiness with which he handed over the samples to me for closer inspection. As to the locality Ad. Jensen reports. ‘‘To the north-east of the colony of Jacobshavn a plain extends for a couple of English miles along the base of the mountains. The plain is watered by a small rivulet, which discharges itself into the harbour. On its way to the harbour it passes through several small lakes or tarns. The Bryozoa were found on the 28% of August 1906 in the bed of the stream at the place where it leaves the uppermost and largest of the small lakes; the height above sea level was са. 30 m. In this place the river is quite shallow. the bed is covered with stones and partly ‘‘moss-grown”. Numerous Sticklebacks (Gasterosteus aculeatus) were swarming about besides the brood of the arctic Char (Salmo alpinus). Numerous curiously formed chitinous sheaths housing the pupa of Simulium adhered to the lower sides of the stones. On handling them I observed a colony of Bryozoa fixed on to the lower side of a stone; on turning round hundreds of stones I at length succeeded in finding one more with a colony attached to the lower side of the stone. Unhappily the stones were both too large to go into any of my glasses so that I had no option but to detach the branches of the Bryozoa from them with a knife. The stream in this place was scarcely more than 7/3 m. deep. I further looked for Bryozoa on stones in the littoral zone of the lake but without success. However a dredging across one of the small inlets of the lake fetched up numerous Bryozoan branches with statoblasts. The lake itself is a ‘‘cold” one being comparatively deep; it is fed by the melting snow of the moun- tains and has an outlet. In contradistinction to such lakes | 67 call the smaller lakes. or ponds that have neither affluents nor outlets “warm” lakes; the temperature of these shallow, stagnant waters is in summer often comparatively high. I measured 15° C. in one of these very shallow ponds; in the latter the ice melts early in summer; they were free from ice when we arrived at the ‘‘South eastern” bay on the 20 of June, whereas the colder lakes were still covered with ice which did not melt until the last days of June. With regard to the animal life of these lakes a characteristie difference was noticeable, the shallow, warm lakes producing an abundant fauna; on hauling a plankton net through the water small animals such as Branchinecta paludosa, Copepoda, Cladocera, Rotifera etc. appear in great numbers in the net. Notwithstanding several hauls in a couple of cold lakes I obtained no micro-organisms visible to the naked eye. In the lake near Jacobshayn, at the bottom of which the Bryozoa occured I likewise fished in vain with my plankton net; the only live animals observed were a small arctic Char and a good many larve of a gnat (Chironomus) about an inch long, which enclosed in their tubes of mud came up from the bottom along with a tangled mass of Bryozoa, Characea and moss. It may further be remarked that according to Rink’s (I p. 39) twelve years of observation the mean temperature at Jacobshavn is in Jan. — 14°2, Feb. — 15°2, March —11°6, Ap. — 6'7, May — 0:1, June + 3:7, July + 5°9, Aug. +43, Sep. + 1:0, Okt. — 9:5, Nov. — 9-1, Dec. — 12°2.” The Bryozoa proved to be Fredericella sultana Blumenb. The form of the colony was the usual one with spreading branches well apart from each other and much resembling those 1 had seen from the abyssal region of Lake Geneva and figured by Forel (1901 p. 114); the tubes contained the well known brown kidney shaped statoblasts without annulus. The colour of the tubes was a pale yellow, in the youngest parts almost white; they lack the Diatom-coating so charac- 68 teristic of the Danish Fredericella (W.-L. 1896 р. 262) whereas grains of sand were observed here and there in the fragil and soft tubes, in order to make them firmer. In the sample handed over to me from the above mentioned lake the Frede- ricella were entangled in a mass chiefly of Characea inter- spersed with Fontinalis. Evidently the feeble, pliant colony clung to the Characea along the stems of which they possibly branched and twined for support. The length of the tubes at any rate measured 4—5 cm., possibly considerably more. A further inspection of the sample from the rivulet revealed some few specimens af another Bryozoa: Paludicella Ehren- bergii v. Benned. attached to the branches of Fredericella. In our native lakes it is by no means a rare sight to see Palu- dicella coating the branches of Fredericella. It must now be considered as a matter of fact that the fresh-waters of the arctic zone are inhabited by at least two fresh-water Bryozoa: Frede- ricella sultana and Paludicella Ehrenbergii. A closer perusal of the literature consequent on the present find showed that although no Bryozoa colonies had as yet been recorded from the polar zone their statoblasts had been noted. B. statoblasts are reported from Spitzbergen by Richard (1897 p. 1); P. fruticosa from the Murman coast (1901 p. 23) and P. repens by Levander from Russian Karelien (1905 p. 33). Whilst the presence of statoblasts in one of our home- localities may probably always be considered as a sure sign that the species to which the statoblasts belong will also occur in the locality, the case may be different when the statoblasts occur at so great a distance from the limits of the domain the growing Bryozoan colonies have hitherto been known to occupy, the dispersing powers of the statoblasts being as is well known, very great. In order more definitely to ascertain the northernmost locality from which living fresh-water Bryozoa colonies have been reported I applied for better information on this head to 69 Scotland, Norway, Sweden and Finland. Mr. James Murray advised me, that outside the reports af Dalyell and All- mann no knowledge had been gained as to their distribution in Scotland. Prof. G.O.Sars informed me that in the vicinity of Christiania he had met with Plumatella repens (fairly com- mon) Cristatella (only in one locality) and probably also with Fredericella; otherwise nothing was known at to their distri- bution in Norway excepting from Krapelins reports. Ekman writes me that Bryozoa are not known to occur in Swedish Lapmark; at the same time he reports Cristatella, Plumatella repens (?), Plumatella fungosa, and Paludicella as having been found in Sweden, however their utmost boundary lay just to the north of the great Swedish lakes. Levander reports that hitherto Paludicella, Fredericella, Cristalla, Plumatella repens, fruticosa, fungosa and punctata have been found in Finland. With the exception of P. repens which is said to be generally distributed throughout the southern and central parts of Fin- land, the other forms have only been found in some few lo- calities in the southern part of the country’. As the above shows Ad. Jensen’s find is of no small interest, it extends the northern limits of the Bryozoa from 60° N. to 70° N. and is the means of bringing about an agreement in the distribution of the Bryozoa towards the north and their occurence in Alpine lakes, in the abyssal region of lakes in low countries as also their distribution in pre- historic times. It is worth while to notice that the form, which according to the common evidence of present observers in more tem- perate latitudes seems to thrive best at the lowest temperatures: Fredericella sultana (Zschokke а. 0., see above) so far like- wise proves to be the dominant form towards the north. Knowing ! I beg to express my best thanks to each of the above mentioned scientists for their kindness in thus having placed their knowledge at my disposai. 70 as we now do that the artic zone houses fresh-water Bryozoa, and that probably other species than those here mentioned may be expected to occur, our researches must aim at a better under- standing af their mode of reproduction. It is a well known fact, that by far the greater part of the investigations regarding the reproduction of the lower fresh- water organisms have until a few years ago taken place ex- clusively in Central Europe. Owing to studies pursued in this from a geographical point of view very limited area our know- ledge on this head has been based. It seems to have been tacitly understood that the results arrived at from this territory must hold good in any other locality where the lower fresh- water fauna happened to occur, i.e. almost all over the surface of the earth. During later years a series of publications. have appeared. on this fresh-water fauna, resting on investigations carried on in artic and North European as well as in the high alpine lakes of Switzerland, in Italy and North Africa. In Central Europe these studies have further been carried on with some regard to the conditions to which the organisms occurring in this territory are subjected. Of this extensive literature we shall here only mention the general results that have been gained, which further researches will more fully substantiate. In all the lower fresh-water groups of animals with various modes of repro- duction — digonic or monogonic (parthenogenesis, gemmation, division) or producing two types of eggs (resting eggs with thick shells and summereggs with thin shells) the two modes of reproduction are not employed indiscriminately under all climatic conditions nor in every locality; nor are the two types of eggs everywhere utilised to the same degree. This is the case with the Copepoda, Cladocera, Ostracoda, Rotifera, Bryozoa, Planaria, Dinoflagellata and will in the future probably likewise prove to hold good with regard to the Phyllopoda. In certain latitudes and under certain conditions the monogenic propagation prevails, in others the digonic. The circumstance that organisms 71 endowed with various modes of reproduction employ these differently under differing external conditions | regard as an in- disputable fact, which in my opinion has hardly been appreciated by zoologists, whilst to botanists, whose knowledge of the life- conditions and vital requirements of plants exceeds by far that of zoologists with regard to animals it has long been an acknow- ledged fact. In botanical literature it has often been emphasized, that sexual reproduction is abandoned in high latitudes, and that plants living under arctic conditions increase either chiefly or exclusively vegetatively. To mention an example Nathorst (1883 p.64) reports that a great many of the Spitzbergen plants produce no fruit at all; the phenomenon is even observable in the Feroe Islands (Ostenfeld 1901 р. 106 and 1906 р. 41 where further literature is cited). In botany it is so pronounced, that plants which in a given locality do not produce ripe seeds are considered by some botanists as relicts, a view which how- ever can hardly be supported (Warming 1904 р. 74). With regard to plants fertilized by the aid of insects it is of course often the absence of the proper insects which forms a hindrance in this respect. Ostenfeld further remarks, that with regard to wind fertilized plants the explanation of the above feature must be sought for in climatic conditions, more especially the low summer temperature — the same interpretation as has been propounded in recent zoological literature on the various modes of propagation of the lower fresh-water organisms in high northern latitudes. I shall not here enter upon this now pretty. extensive literature, comprising numbers of greatly differing organisms, but only restrict myself to a few remarks respecting the Bryozoa. Already in 1896 (p. 350) I was of opinion, that the sexual reproduction of the Bryozoa decreases towards the north. Not- withstanding regular fortnightly investigations made upon colonies of P. fruticosa, Fredericella and Lophopus in their habitual 72 places of growth, I was never able to find either larvæ, eggs or spermatozoa. This is in all essentials in accordance with the results arrived at by Kraepelin with respect to North Ger- many (see W.-L. 1897 p. 344—349) and further corresponds with Zschokkes reports on his researches respecting Bryozoa in high Alpine lakes. Zschokke states, that he has never seen any sexual elements in the Plumatella colonies of lakes in- vestigated by him, and that these Alpine Bryozoa possibly — he does not wish to express himself positively — may prove to form an interesting parallel to the colonies of the northern regions (1900 p. 119). Thanks to Kraepelins investigations we now know that in North Germany Paludicella produces eggs as well as spermatozoa, a feature which will probably also hold good with us. The larves have only once been found in the vicinity of Breslau (Bråem 1896 p. 54). Since then 1 have continually been in search of them in and on the large Palu- dicella colonies in Fure- and Lyngby-Sø but as yet without success. Whilst neither Kraepelin nor I have ever seen the Fredericella larva, Chirica (1904 p. 2) reports, that in the Rumanian lakes the /redericella throw off their larves in the latter end of July; these larva haves further been observed by Bräem as far as I know near Breslau (1895 p. 503). In our latitudes the production of eggs and sperms along with a copious produce of larve can only be regarded as a common feature in Plumatella repens, fungosa and in Crista- tella. Further researches must now decide, whether not only the forms, that already with us seem to have abandoned more or less the sexual mode of reproduction (Fredericella, Pluma- tella fruticosa. and possibly also Paludicella Ehrenbergii) but likewise all the rest of the Plumatella species as well as Cri- statella, both of which will in time presumably be found in the arctic region, and which in our latitudes all produce larvæ abundantly, only propagate asexually in the far north. This would seem the more probable, as the arctic conditions un- 73 questionably shorten the growth period of the Bryozoa. From his researches in Tilisuna- and Lüner-See ca. 2000 m. above sea level Zschokke (1900 p. 117) remarks, that the period of active growth in Alpine lakes can only be estimated at 8—10 weeks, whereas in low countries at 20—22 weeks. The pro- duction of the statoblasts does not take place until ca. 9—10° C., i. e. in the latter part of July, and already in Oct. the colonies are dead. During the period Oct.—July only the germs winter in the statoblasts. According to Rink’s statement as to the mean temperature of Jacobshavn it appears, that the above mentioned lake has hardly been free from ice for more than three months. “Generally speaking the ice begins to form at the end of Sept., and in the course of Oct. the lakes are quite frozen over; the ice does not wholly vanish until the beginning of July or even later” (Rink I, p.76). The period of the year when the temperature exceeds са. 9—10° С. is undoubtedly very short. Notwithstanding the severity of the climate the colony might in all probability survive the winter in the case of a favorable locality; in 1899 p. 45 Lampert mentions the Fredericella as being the only Bryozoa positively known to be able to live beneath the ice. A few years ago (1904 p. 337) Zykoff was able to report Estheridæ as having been found оп Kolgujew-Island at са. 70° N. with an isotherm of ca. 7—8° C. in July. This discovery at one stroke extended the limits of distribution of these or- ganisms from regions bordering on the Mediterranean, from the Hungarian steppes and from the Mongolian as far north as to the arctic zone. The discovery of the Esteride along with that of the fresh-water Bryozoa treated of in this paper in the first place goes to show how very little we at present know as to the arctic fresh-water fauna. It has of late be- come customary, from a knowledge of the lowest July tem- perature at which a given organism at the present time is supposed to be able: to live, to draw conclusions as to the 74 temperature at which those strata in which the fossil specimens of the species now occur. For several reasons I consider these conclusions as being of small worth; more especially on account of our want of knowledge as to the northernmost limits of the lower fresh-water fauna.

Medfødte Misdannelser m. m. hos den grønlandske Befolkning. Ved Gustav Meldorf. 1907. XXXIV. 6 I det efterfølgende har jeg samlet, hvad jeg selv har set, samt hvad jeg i Literaturen og i Distriktslægernes indberet- ninger fra Grønland har kunnet finde angåaende medfødte Mis- dannelsers Forekomst hos Befolkningen i Grønland. — Skjøndt Materialet til Belysning af dette Forhold ikke er stort, synes det dog tilstrækkeligt til at vise, at de fleste af de fra andre Nationer bekendte almindeligste Misdannelser ogsaa træffes hos Grønlænderne, og jeg skulde næsten tro, at de endda er for- holdsvis hyppige hos den grønlandske Befolkning. Man vil i det efterfølgende finde Exempler paa: ufuld- stændig Lukning af føtale Spalter i Ansigtet, ufuldstændig Lukning af Cerebrospinalaxens Hulheder, Cyklopi, Hermafrodi- tisme, fejlagtig Dannelse af anus, fejlagtig eller mangelfuld Dannelse af Extremiteter m. m. — Om Dobbeltmisfostre og hjærteløse Misfostre (Acardiaci) foreligger ingen Oplysninger. En Mola hydatidosa, der fremkaldte stærke Blødninger og paafølgende Abort i 3die—4de Maaned, saa jeg hos en 31 Aar gl., gift Grønlænderinde ved Julianehaab d. 7”/s 1897. — I 1896 behandlede Fritz Jørgensen, ligeledes ved Juliane- haab, en «Metrorrhagia gravissima, Mola hydatidosa» (manuel Fjernelse af Mola). Et Exempel paa ufuldstendig Lukning af fotale Spalter i Ansigtet saa jeg hos en ca. 18-aarig, ugift, for- ældreles Kvinde fra Grønlands Østkyst, der i Eftersommeren 1900 indvandrede til den sydlige Del af Vestkysten tilligemed 37 andre Beboere af Ostkystens sydlige Del for at bosætte sig 6* 80 paa Vestkysten. Jeg traf og vaccinerede disse Ostgronlendere ved Udstedet Pamiagdluk 4. 7“/s—?*/9 1900 og har nærmere beskrevet mit Sammentræf med dem i en lille Afhandling i «Meddelelser om Gronland» XXV Hefte, Kbhvn. 1902, betitlet: «Fra en Vaccinationsrejse i Egnen omkring Kap Farvel i Efter- aaret 1900». Hos den ovennævnte Ostgronlenderinde saas en medfodt mangelfuld Tiliukning af den fotale Spalte imellem den af forste Visceralbue dannede Over- og Underkæbelap paa begge Sider. Paa venstre Side var denne Spalte forbleven helt aaben- staaende paa et længere Stykke, saaledes at Mundspalten strakte sig i transversel Retning lige hen til, hvor de ægte Kindtænder begyndte (Fissura buccalis transversalis, Macrostoma). Længere bagtil havde Tillukningen af denne fotale Spalte paa venstre Side for starste Delen fundet Sted; dog saas endnu ca. 1 Tomme nedenfor og foran venstre Oregang en lille, spalteformet Kanal, i hvis Lumen, der var saa stort og saaledes formet, at en Hul- sonde kunde trænge derind, den normale Hudbeklædning strakte sig ned, saa langt man kunde se. Lige bagved denne spalte- formede Aabning i Huden saas en lille nogenlunde oreformet Hudlap, der i Forening med Kanalen foran dannede ligesom et Miniaturere med den tilhørende Oregang noget nedenfor og foran det normale Øre. Paa Ansigtets hojre Side var Mundspalten ikke forlænget udover det normale, men her saas to lignende Kanaler (spalte- formede Aabninger) i Huden som den ovenfor beskrevne enkelte paa venstre Side. Paa Kinden omtrent midt imellem højre Mundvig og højre Øregang saas den ene af de nævnte to smaa, spalteformede Aabninger og bagved denne en ærtestor, lidt oval, fibromlignende Lap. Endvidere saas en noget større Hudlap foran Lobulus af højre Øre, og foran og lidt opadtil for denne saas den anden spalteformede Aabning at strække sig ned i Huden. Misdannelser af Hovedet о. а. Legemsdele i højere 81 Grad synes at have været tilstede i et Par af Paul Egede («Continuation af Relationerne» etc., 1734—1740, Kbhvn. 1741) beskrevne Tilfælde af medfodte Misdannelser, nemlig: «Den 28de» (Marts 1738) «blev ved Isefjorden fod et Monstrum, hvilket havde Øjnene paa Siden af Nesen, Munden var som en spids Hunde-Snud; havde ingen Ørn. Og i Stedet for Hænder og Fødder havde det ikkun Laller og store tykke Laar. Over Panden var det begroet med Rens-Diurs Haar. Paa Siden af det var det at se til som et Stykke Hvidfiskeskind. Et andet Barn, sagde de, var fød der i Nærværelsen og havde lugtet af Orme. Aarsagen til slige Vanskabninger, foregive Angekut, at være, at Moderen har ladet sig bruge af de Døde». «Den 9de» (Maj 1739) «blev født et Monstrum 2 Mile herfra uden Hoved, med fire Ben, store Negler, Mund påa Brystet og Klør paa Ryggen. Slige og andre Vanskabninger fødes tit her i Bugten». Under mit 6-aarige Ophold ved Julianehaab fik jeg Lejlighed til at se to Tilfælde af medfødt Spaltning af Spinalkanalen (Rachischisis, Hydrorhachis ext., Spina bifida lumbo- sacralis) hos Grønlænderbørn. I det første af disse Tilfælde var Patienten et 2 Aar gl. Pigebarn ved Udstedet Sydprøven med Coxitis og «Tabes meseraica» tillige, hvem jeg kaldtes til d.‘/9 1898. Det spinale Meningocele havde en bred Basis og var blodt og vandpude- agtigt at fole paa; opadtil og bagtil lob det ud i en Spids, hvortil yderligere var fæstet et lille morkerodt, ved Tilheftningen til Meningocelet indsneret, kodet Appendix. ‘Tumor var med- fodt og var vistnok voxet noget siden Fodslen. Intumescensens Længdeaxe var fra Basis og til den fri Spids af det omtalte lille Appendix 51/2 Centimeter; heraf udgjorde det sidste 7/4 Cen- timeter. En aragtig Indtrekning saas i Huden nedenfor Me- ningocelet. Indenfor Basis af Tumor foltes tydelig Defekten i Hvirvelbuerne (manglende processus spinosi osv.). Den dækkende Hud af naturligt Udseende. — Barnet, hvis Forældre var meget 82 fattige, var i elendig Ernæringstilstand og overmaade slet soig- neret; det døde senere (4/2 1899). Den anden Patient, et 11/2 Maaned gl. Barn (Dreng) fra Udstedet Narssak (Nordproven), blev indlagt paa Sygehuset ved Julianehaab d. >7/s 1899. Meningocelets Basis var her 5 Cen- timeter i Diameter; den dækkende Hud var rodviolet, stærkt udspilet, slimhindeagtig i Midtpartiet, blank og spejlende. Kon- sistensen spændt og fluktuerende. Svulsten punkteredes ved Dieulafoi’s Aspirationsapparat, og der udtomtes en ret betydelig Mengde aldeles vandklar Vedske, hvorefter Sekken faldt sam- men, og Defekten i Hvirvelbuerne kunde nu overordentlig tydelig foles herigennem. Men Vedsken reproduceredes trods Trykfor- binding meget snart, og Sækken blev atter udspilet heraf. Barnet befandt sig vel under og efter Punkturen. Forældrene vilde ikke indlade sig paa, at storre Indgreb blev foretaget og havde bestemt at rejse fra Kolonien allerede d. *°/s med Barnet. Dette, der altsaa kun opholdt sig 4 Dage ved Kolonien, døde d. !*/ıı ved Bristning af Sækken, hvilken Bristning Barnet over- levede i 2 Dage. Et Tilfelde af Cyklopi omtales af Distriktslege Pfaff, Nord-Gronland, i hans Indberetning for Aaret 1867: Ved Jakobs- havn fødtes i Stutningen af Juni Maaned «et dodfadt Misfoster. Øjnene vare sammensmeltede ved Næseroden. Næsebenene manglede, men ned over det sammensmeltede Øje hang fast- hæftet til Neserodens Hudbedekning en kødet, af en Aabning perforeret Klump. Paa ventre Fod fandtes 6 Teer, iøvrigt var Barnet fuldbaaarent og velskabt». Under mit Ophold i Grønland blev det mig fortalt (1899), at 3 Tilfælde af Kryptophthalmus? skal være sete ved Nanor- talik for en Del Aar siden, idet en gift Grønlænderinde, der først havde født et Par sunde Børn, derefter fødte tre Børn, det ene efter det andet, hvor Øjelaagsspalten (rima) helt eller delvist manglede paa begge Sider. — Hos det første Barn skal Tillukningen have været saa fuldstændig, at man aldeles intet 83 kunde se af Bulbi, hos de to andre Born saas derimod et lille Parti af Cornea («saa meget som et Spurveoje») at skinne frem i Midten af de iøvrigt tillukkede Ojelaagsspalter. — Alle tre Bern skal have haft Lyssands (drejede Hovedet efter Lyset); de dode alle i en ret sped Alder, og Moderen fodte senere atter sunde Born. Af Hermafroditisme saa Distriktslege Otto Jessen ved Julianehaab et Tilfælde, der omtales i hans Medicinalberet- ning for September 1872—September 1873: «Som Merkver- dighed vil jeg kun tilføje til min Indberetning, at der i den tyske Menighed er bleven fedt et Barn med saa hermaphroditisk misdannede Genitalia, at der var Strid, om det skulde dobes Carl eller Marie, men Missionæren døbte det som Dreng. Da jeg paa min Rejse undersøgte det, var han 3 Maaneder gl.; Clitoris var udviklet til en ca. > Tomme lang Penis, næsten uden paaviselig Preputium, men forholdsvis stor Glans med fin, næsten hypospadiær Urethralaabning, derunder en Aabning, saa stor, at man kunde stikke en ikke meget fin Sonde */4 Tomme i Dybet; begge Testes foltes med Funiculi i Labia majora». Muligvis kan der have veret Tale om Hermafroditisme i sterre eller mindre Grad i et Par af Paul og Niels Egede omtalte Tilfælde. lalfald som Kuriosum synes jeg, at de for- tjener at anfores her: Paul Egede fortæller i «Continuation af Relationerne» om еп Kone, der 4. 23de Marts 1738 sagde til ham: «Jeg fødte dette Barn i Sommer og var en Dreng, det forste han kom ud, men han revnede og blev til en Pige; uden Tvivl er Luften bleven vred for noget, jeg maa have forset mig udi». — — — «Г hvor meget jeg end søgte at igendrive hende, stod hun dog paa sit, og sagde: Det var en Dreng, men revnet». — I «Tredie Continuation af Relationerne» etc. 1739—1743, Kbhvn. 1744, skriver Niels Egede for d. Tde December 1741: «Iblandt andet sagde en Kone, at den lille Pige, som hun nu havde, var en Dreng, da hun blev fodt, som de alle saa, men 84 da Jorde-Moderen havde forset sig i noget, idet hun ikke havde taget alle Angekokkens Regler iagt, sprak han itu og blev til en Pige, som duser’)». Niels Egede var da rejst Nord paa til Isefjorden, hvor dette foregik. | December 1739 omtaler Niels Egede en Brud, der Brudenatten blev forvandlet til en ung Karl. Bataillonschirurg Rudolf, Nord-Gronland, angiver i Aaret ‘lz 1845—30/в 1846 at have behandlet et Tilfælde af Atresia urethræ; om medfodt eller erhvervet angives ikke. Et Tilfelde af Atresia ani omtales i Distriktslege F. Block’s Medicinalberetning for Godthaab Lægedistrikt for 1/7 1840—*°/6 1841: Anus imperforatus, medfødt: «en tynd Hinde tilsluttede Aabningen, men ved en sterk Nisus depressonus anden Dagen efter Fødslen sprang denne Hinde itu paa to Steder. Anus blev dog herved ualmindelig lille og maatte i 5- Aars-Alderen dilateres blodigt. Barnet sagdes da ikke at have haft Aabning i 5 Uger!, og der udtemtes efter Operationen (uden Clysma eller andre Afforingsmidler) Masser af Feces». Barnet var en Dreng. Hudstrimmelen gennemskares med Fistel- kniv. Exempler paa fejlagtig eller mangelfuld Dannelse af Extremiteter er allerede nævnte i det foregaaende (under Omtalen af Misdannelser paa Hovedet og Cyklopi). I det efter- folgende skal anfores flere andre Exempler herpaa: Distriktslege Pfaff, Nord-Gronland, fortæller i sin Medicinal- beretning for Aaret 1872 om en Fodfodsel, hvor Moderen døde 3 Timer efter Fodslen, da Jordemoderen ikke var i Stand til at 1) Om en lignende formodet Forvandling fra Dreng til Pige (allerede i Foetallivet) paa Grønlands Østkyst meddeler Kommandør С. Holm i «Ethnologisk Skizze af Angmagsalikerne» (Den ostgrenl. Expedition 1883—85, Side 134, Meddel. om Grenland, X Hefte, Kbhvn. 1888): En Angekok havde forudsagt en Kone, at hun vilde fode en Sen. Barnet blev imidlertid en Pige. Senere fandt Angekok’en ud af, at Spaadommen vilde være gaaet i Opfyldelse, hvis Konen ikke ved Uforsigtighed engang var falden, hvorved der var gaaet en Revne i Fosteret». 85 faa Efterbyrden frem. (Pfaff formoder, at der har veret ud- bredte Adhærencedannelser tilstede). «Bemeldte Barselkone havde fodt flere Born, og ikke faa af dem have haft Abnormi- teter saaledes Fingrene forenede ved Svommehud eller aldeles manglende; det nyfodte Barn manglede saaledes Tommelfingeren paa hojre Haand». Knud Poulsen anforer i «Contributions to the anthropo- logy and nosology of the East-Greenlanders» (Meddelelser om _Grenland XXVIII Hæfte. Kbhvn. 1905): «More considerable deformities are certainly very rare, children with such being as a rule undoubtedly killed shortly after having been born. The only one I saw was a young man, whose left hand was somewhat deformed, being first nearly 4 Ctm. shorter than the right one; the outermost points of the three middlemost fingers were besides stiff, and between these, being very delicate, a web was distended reaching nearly the outermost point». — I «Ethnologisk Skizze af Angmagsalikerne» skriver Kom- mander G. Holm om Ostgronlænderne: «Det er vistnok ingen Sjeldenhed, at der fodes vanskabte Born. Disse tilligemed syge Born, som antages ikke at kunne leve, ligesom ogsaa Born, hvis Moder dor under Fodslen, og hvem ingen anden kan give Die, blive kastede udenfor paa Jorden eller i Havet for at om- komme». — — Hos en nogle og fyrretyve-aarig, gift Gronlænder, Fanger fra Bopladsen Kangermiutsiait i Nærheden af Kolonien Juliane- haab, som kom til Lægebehandling for en anden Lidelse d. ?/6 1902, saa jeg et Exempel раа Syndaktyli, idet Ade og 5te Taa paa venstre Fod var fuldstændig sammenvoxede i hele Be- roringsfladernes Udstrækning. Sammensmeltningen, der var med- fodt, indbefattede Huden, ikke Muskler, Sener eller Knogler. De sammensmeltede Tæer saa ud som en enkelt meget bred Taa med 2 Negle. Paa 4de Taa var Neglen veludviklet; paa dte Taa var den uregelmæssig kort og bred, rudimenter. Polydaktyli saa jeg d. 30/4 1902 hos en ca. 5 Aar gl. 86 Gronlænderdreng fra Bopladsen Niakornak, Nord for Kolonien Julianehaab. Barnet havde to Tommelfingre paa venstre Haand, hvoraf den ene (den yderste) dog kun var са. Из saa stor som den anden (den egentlige Tommelfinger). De var begge ind- leddede (ved Ledforbindelse) paa forste Mellemhaandsben. Den lille overflødige Tommel havde (ligesom den storre) 2 Phalanx- Knogler, og der var Bevegelighed i alle Led (ogsaa Metacarpo- phalangeal-Leddet). Yderste Phalanx var dog skudt ned paa Ulnarsiden af 1ste Phalanx, saa at den lille Tommels yderste Led vendte imod den storre Tommelfinger. Patienten kunde selv bevæge i alle Led. Begge Fingre bar vel udviklede Negle; paa den lille Tommelfinger var Neglen lang og smal. Niels Egede («Tredie Continuation af Relationerne») skriver i August 1739: «Sidst i denne Maaned kom en Gren- lænder langt Sonden fra, som var vanskabt, hans Mave ragte lige fra hans Hals, og kunde jeg ikke fole til noget Brystben paa ham, Albuen var nærved Skulderbladet, Laarene vare om- trent en fjerdedel Alen, og hans Hojde i sig selv var som et ordinært Menneske. Han talede uforstaaeligt, hans Kammerat sagde, at han kunde spise 5 Sælhunde op i et Maaltid, de indbildte sig og, at han havde en Spaadoms-Aand og kunde sige tilkommende Ting. Hans Moder fortalte mig, at da hun engang var paa Jagt og af Mathed lagde sig ned ved en stor Sten for at faa Hvile, drømte hun, at en Trold laa hos hende, og da hun af Alteration vaagnede, var hun ganske mat og merkte ved sig selv, at hun var besvangret». »Hun bad mig, at jeg vilde tale til Gud for hende, at den vanskabte Sen maatte enten blive som andre eller og maatte de, thi han fortærte al hendes Ejendom og kyste Livet af hans andre Soskende». Kommandør G. Holm nævner i »Den ostgronlandske Expedition», Side 87, en Ostgronlænder ved Imarsivik, «som var Dverg». — Hans Datter roede i Kajak og fangede godt. En gift Gronlænder ved Kolonien Julianehaab, født i Aaret 87 1874, lider af dobbeltsidig pes equinus samt genu valgum, medfodt eller da i alt Fald udviklet i den tidlige Barnealder. Af mindre væsentlige medfødte Anomalier skal jeg nævne: en for vidt gaaende Tilheftning af Tungen til Bun- den af Mundhulen (Ankyloglosson), en for vidt gaaende Til- heftning af Overleben til Overkebens Gingiva samt to Tilfælde af Molluscum fibrosum pendulens faciei, det ene hos et dansk, det andet hos et gronlandsk Barn ved Kolonien Julianehaab. De to sidstnevnte Tilfælde stod vistnok i Forhold til den fotale Spalte imellem Over- og Underkæbelappen; der var dog intet Tegn til Makrostomi hos noget af disse to Born. Ankyloglosson saa jeg hos et 14 Maaneder gl. Barn, Datter af Enke, ved Udstedet Narssak (Nordproven) d. "7/7 1900. Barnets Tungebaand (Frenulum lingue) var tilheftet meget langt fortil paa Undersiden af Tungen, næsten helt hen til Tunge- spidsen, saa at Tungen kun kunde loftes ganske lidt op fra Mundhulens Bund og ikke rekkes frem af Munden. Hos et andet Gronlenderbarn, 8 Maaneder gl., Son af Ko- lonist ved Julianehaab, som jeg 4. !Y/s 1901 ВК under Behand- ling, var Tungens Bevegelser ligeledes stærkt indskrænkede paa Grund af Tungebaandets Tilheftning altfor langt fortil paa Tun- gens Underside. Hos begge Born foretoges «Løsning af Tungen» ved Indklip- ning med Sax i Tungebaandet. Efter den lille Operation blev Tungens Bevegelighed betydelig mere fri. — Hos begge Born saas tillige en hvidlig Plet (Stomatitis aphthosa), der hos det forst omtalte Barn var 10-Оге stor og havde sit Sede paa Tungespidsen; hos det sidstnevnte Barn var Pletten godt ertestor og havde sit Sede lige foran Tungebaandets overste og forreste Tilheftning (halvt paa Tungebaandet og halvt paa Tungens Underside); Moderen havde bemærket denne Piet siden 4. 2/1 1901. Under flittig Pensling af Pletten med Tinct. myrrhe & galle aa tabte den 58 sig mere og mere og var næsten helt forsvunden i Slutningen af Marts. Det synes næsten, som om saadanne strammende Baand i Mundhulen, der ikke heves ved artificiel Behandling, er serlig udsatte for at angribes og — ialtfald delvis — destrueres ved at blive Sædet for Betændelsesprocesser (Aphthe о. Ign.), hvorved der indtreder en Slags Naturhelbredelse af Anomalien. Jeg har set det i flere Tilfælde, ogsaa naar Frenulum imellem Over- leben og Gingiva har strakt sig helt ned til Fortænderne. For- modentlig finder dette Forhold sin Forklaring ved, at en saadan fri Rand stadig er udsat for Stramning og Irritation under Tungens og Overlebens Bevegelser. Fibroma (Molluscum fibrosum), medfodt, saa jeg hos et Grenlenderbarn ved Julianehaab, født 4. */6 1901, Son af Fanger. Tæt foran højre Ore (i Højde med Crus helicis, altsaa lidt ovenfor Øregangsaabningen) saas en rundagtig, lidt mere end hampefrøstor, stilket Tumor, bestaaende af normal Hud med Lanugohaar (Cutis pendula). Stilken var tyndest lidt ovenfor den øvrige Huds Niveau. Hos et dansk Pigebarn ved Julianehaab, der fødtes i April S. Å., altsaa et Par Maaneder i Forvejen, saas et lignende med- født Molluscum fibrosum foran venstre Øre. Umiddelbart foran Tragus (paa Overgangen mellem denne og Tindinge-Egnen) fandtes et 4 Millimeter langt Appendix af blød Konsistens, bestaaende af normal Hud.. Det havde Cylinderform, og Cylindrens Diameter var 2 Millimeter. Cylindren var indsnævret lidt ovenfor Huden. Begge disse smaa Tumores fjernedes let ved Afklipning med Sax (henholdsvis d. ?/1 1902 og d. ”/10 1901), og i Løbet af faa Dage var Snitfladen legt og dækket af Epidermis. Phimosis er yderlig almindelig hos Drengebørn og voxne Grønlændere. Af Hydrocele congenita har jeg set et enkelt Tilfælde hos en Grønlænderdreng. 89 Skjendt det efterfølgende egentlig ikke kan komme ind under Betegnelsen: medfodte Anomalier, vil jeg dog tillade mig i Til- slutning til Omtalen af disse at anfore et Par lagttagelser over Forhold hos Gronlænderborn, der ligger lidt udenfor det helt almindelige og dagligdags. Da jeg 4. 17/5 1901 opholdt mig paa Embedsrejse ved An- leget Nanortalik i Julianehaab Distrikt, fremstillede en ugift Gronlenderinde sin 9-aarige Datter for mig for at faa fjernet en frembrydende Tand, der generede Barnet en Del under Tyg- ningen m. m., idet den var kommen frem paa den haarde Gane en Centimeter bagved Mellemrummet imellem de to mediale Fortender i Overkeben, altsaa i Legemets Midtlinie (Sagittalplanet). Foruden denne Tand havde Barnet 12 Tender i Overkeben (2 Fortender, 1 Hjornetand og 3 Kindtender i hver Kæbehalvdel). | Undermunden saas de tilsvarende 12 Tender, og desuden var 2den Molar i sterkt Frembrud i venstre Side. De to Hjorne- tender i Underkæben var ved at blive erstattede af to frembry- dende, blivende Hjornetænder. Disse var komne godt frem over Tandkødet paa den ydre Side af Mælketænderne (lidt udenfor dem), saa at Barnet da havde 4 Hjørnetænder i Underkæben. De to Hjørne-Mælketænder kunde kun rokkes forholdsvis lidt. Den lille, hvide, frembrydende Tandkrone, der saas i Midt- linien af den haarde Gane, havde nærmest Form som en For- tand (mejseldannet med en Køl paa den bagtil vendende Flade). Dens Størrelse var lidt mindre end Fortændernes. Efter Ud- trækningen med Tandtang viste den sig at være 9 Millimeter lang, heraf udgjorde Kronen 6 Millimeter. Kronens Bredde var 4—5 Millim.; forfra—bagtil var den 3—4 Millim. Roden var afrundet af Form. Tanden kunde før Udtrækningen rokkes lidt. «Hexemelk» træffes undertiden hos de smaa Grønlænder- bern.

So far as can be ascertained, gyrolite was first observed by К. L. Giesecxe in the year 1811. He gives the following description of a mineral from Niakornat in the district of Umanak, Greenland, which evidently refers to this species"): «Ist aber Mandelstein ein Gemengtheil dieses Conglomerats, so sieht man in demselben Quarz, Chalcedon, faserigen Mesotyp in Nieren von verschiedener Grösse. Der letztere geht oft ins krummblätterige über, ist schiefrig, hat einen starken Perlen- mutter-, oft beinahe metallischen (Silber-) Glanz, und braust etwas mit Salpetersäure. Seine Krystallisation scheint die sechs- seitige Tafel zu sein.» Gyrolite seems to be again indicated by Giesecke in 1814, when, in describing the minerals of Disko, he writes?): «The Apophyllite also occurs in a radiated form similar to stilbite, but with a more brilliant lustre, and presenting on the surface a crystallisation similar to the cock’s-comb barytes.» In this passage the relationship with apophyllite is clearly recognized; but later writers confounded the mineral with me- sole (thomsonite) and even with the radiated zeolites. Thus Haidinger writing in 1827°) describes eight specimens of ‘‘Mesole” from Arran’s collection (now in the British Museum, London), and remarks that "these varieties show a very great 1) GIESECKE, Mineralogiske Rejse i Grønland, Copenhagen, 1878, р. 245. ?)

XXXIV. 7 94 resemblance to certain kinds of Apophyllite, so much so, that Sir Charles Giesecke, who discovered them in the island of Disco, in Greenland, was induced to consider them as a parti- cular subspecies of it, the micaceous apophyllite”. The first five specimens described in this paper by Hamincer are mesole (or faröelite, i. e. lamellar radiated thomsonite) from Nolsö in Ferée, while No. 6, ‘‘discovered by Sir Charles Giesecke at Nia Kornak in the island of Disco, Greenland” !) had a specific gravity of 2°382, and is said to have occurred in reniform groups, the individuals being “similar to those of var. 4, but larger’: it was most probably therefore mesole. But the two last specimens described by Harrncer are, there can hardly be any doubt, gyrolite, as was pointed out by M. Е. Heddle?). They are thus characterized by Haidinger: «7. The size of the plates is here between a quarter of an inch and half an inch. They have a bright pearly lustre on their cleavage planes, and the whole aggregate resembles in no small degree the crystallized spermaceti. The colour of this variety is white, slightly yellowish. It forms part of the inside of a geode detached from one of the vesicular cavities of basalt. It is from Karartut, near Godhavn, in the island of Disco. 8. Large individuals aggregated and coarsely forming reni- form shapes. The surface is dark yellowish-grey, the colour on the cleavage planes almost straw-yellow; the whole ap- parently decomposed. Cleavage is very easily obtained, and the laminæ show some elasticity when we attempt to separate them. This specimen is a native of Nia Kornak in the Ome- naksfiord, like the preceding in the island of Disco.» It is no doubt also gyrolite which is referred to by Lévy”) 1) More properly Niakornat. This locality is not on Disko but on the peninsula Nugsuak, Umanak-Fjord. ?) The Mineralogy of Scotland, 2, 1901, p. 79. 3) Description d'une collection de minéraux formée par M. Henri Heuland et appartenant à M. Ch. Hampden Turner, 1828, 2, pp. 272 and 274. 95 a year later, under the description ‘‘apophyllite globuliforme”, with mesolite and apophyllite, ‘‘Waygat, ile de Disco, Groen- land”; and apophyllite laminaire .... blanc et nacré, globuli- forme radié; Niarkornak, Groenland”. In the year 1851 the mineral species gyrolite was named and described by Anpverson'); the locality was Storr in the island of Skye, one of the Hebrides. The occurrence of gyrolite in Greenland was for the first time expressly stated by Grec and Lertsom?), who concerning that mineral write: ‘‘specimens of it (arranged in Mr. Allan’s collection as mesole by Haidinger) without doubt occur at Karartut, near Godhavn in Disco Island, Greenland; also at Niakomak, Omensnaksfiord, Disco”. With greater certainty gyrolite was proved to be a Green- land mineral by Heppte (see above) and by J. Currie”) who points out some localities in Greenland, where Gresecke may have found the mineral. Of these Niakornat has been named above; from Tarajungitsok Gisecke!) mentions: ‘‘kugelichten Glimmerzeolith in feinen, fast zerreiblichen Blättern”, and by this description gyrolite without doubt must be meant, so much the more as this mineral in reality has been collected by СтезЕскЕ at this place (see later on). From Tupausarsuit (= Tua- pagsuit) Gimsecxe®) mentions “der mehrmals berührte glim- merige Zeolith — blätterig und in Kuben”; here it is also al- most quite certain that he has meant gyrolite. Finally Currie names the locality of Akiarut from which Giesecke®) mentions massive apophyllite” and ‘‘pearl white radiated mesole”; of these the former, in my opinion, may be apophyllite, the latter thomsonite. 1) Phil. mag.

Dublin, 1832, pp. 54, 55. 1 96 When I wrote the ‘‘Mineralogia Groenlandica”, in 19051), I had never seen gyrolite and of the above cited works of Harwincer and Неорте | knew nothing; I thought then, that the occurrence of gyrolite in Greenland could not be considered as certain, so much the more as there did not exist any ana- lysis of the Greenland mineral. Subsequently Mr. Currie made me acquainted with the above cited works and drew my atten- tion to Levy’s description. He also sent me specimens of gyro- lite from different localities, by comparison with which I soon found the mineral in specimens from several localities in the Greenland collections of the Museum of Copenhagen. On a closer examination of these I found that the mineral from Niakornat showed such highly interesting crystallographical and physical development, and in most respects differed so much not only from every formerly known gyrolite but also from almost all other zeolites, that it deserved а special description. In the following, then, I shall first describe the mineral from Niakornat, and afterwards that from the other Green- land localities. In conclusion I have to pay my best thanks to Mr. J. Currie for his kind assistance to me without which I should never have come to make the following examinations. I. Gyrolite from Niakornat. Occurrence. About the occurrence we only know what GieseckE, who alone of all has collected the mineral at this place, states”). The rock is a basaltic breccia (tufa) in which the size of the fragments varies from that of a pea to the weight of several hundred pounds; thev consist of basalt or “Wacke” or amygdaloid, the last of which contains quarz chalcedony and the “faseriger Mesotyp’. Upon the specimens 1) Medd. om Grenl. 32. 2) ie: р. 245. on in the Museum of Copenhagen we can see that the cavities which contain the gyrolite must have been of a considerable size, at least 1—2 dm in diameter. The minerals which accompany the gyrolite are mesolite and apophyllite, and the succession of these is very distinetly the following: mesolite, gyrolite, apophyllite. The mesolite is developed in spherical radiated aggregations of a diameter of с. I cm which cover the walls of the cavities and from which free needles protrude into the gyrolite but only attain the length of about I mm. The gyrolite forms a stratum on the inner side of the mesolite and the thickness of that stratum varies from 1 to at least 5 cm; from that some folia protrude into the apophyllite, which mineral is only found in one specimen and which consists of one very large individual (about 5 cm in diameter) without distinct crystalline faces; it seems that its form has been partly influenced through contact with other individuals of the same mineral which no longer exist. The gyrolite is, as is otherwise the case, crystallized in radiated, foliated groups; the common size of the folia varies from 0:5 to 2 cm, the arrangement of the folia is however not so regular as commonly, for distinct spherical aggregates are not to be found, and the folia are often seen to intersect each other and in some places to form quite a complicated network. Here and there freely developed folia are seen to protrude into small cavities and these have given me the material for crystallographical examination. Crystalline form. The crystals have the habit of very thin hexagonal tables, the edge of which is mostly, by altera- tion as I think, quite uneven and without distinct faces; in some cavities it is possible to find better developed crystals with rather plane and shining marginal faces, which have al- lowed the following measurements to be made. What is so far known of the crystalline form of gyrolite is very little. Giesecke describes the form as hexagonal tables; 98 Неррте |) obtained from the Treshinish Islands six-sided plates with the plane angles с. 128° 50’ and 115°; I cannot understand how he has got these angles, which harmonize so little with the fact that the mineral is uniaxial. Heddle de- scribes, too, one or two bewelling faces on the edges, which he mentions as very brilliant and smooth; unfortunately he has not measured the position of these faces. For the gyrolite from Niakornat I have found the following: Crystalline form rhombohedral tetartohedral (rhombohedral class of Grora); the tetartohedrism is only to be seen by the etching figures. Axis с —) 19360. The following forms have been found: c {0001}, r {1011}, u {1012}, determined by the measurements: Average Variatic Number of Calculated value APES measurements value rie = (1011): (0001) = 65° 54’ 64°19'-67°23' 5 и:с = (1012): (0001) = 48° 3’ 47°25'-48°42' 3 48° 11' rir = (1011): (0111) = 75° 58' 1 Ton As will be seen the values are divergent to a rather high degree, so that they cannot be considered as very exact. This arises from the fact that the faces are not well adapted for measurements; the faces of ce {0001} are large and shining but mostly curved in dif- Fig. 1.

The rhom- bohedral faces are sometimes shining enough, but they are al- ways very small and furthermore somewhat curved; the reflec- tions, which they give, are of course mostly very indistinct. There cannot, however, exist any doubt about the correctness 1) Min. Mag. 8, 1889, p. 272. 99 of the two determined rhombohedra, allthough the form {1012} is in other cases one of the rarest of all. The complete form of the crystals is given in figure 1. On some crystals there can be seen small, very indistinet negative rhombohedra but these give no reflections. No twins were observed. Etching figures are readily produced with the aid of cold hydrofluorie acid or hot diluted hydrochloric acid, in both cases the effect lasts at the most only a few seconds. The Fig. 2. Gyrolite, Niakornat. The etching figures on the upper and lower basis are direeted opposite to each other; the former ones have the point of the triangle turned down- wards. — The enlargment 1:45. figures are of a sharp triangular form, most commonly with concave edges as will be seen on figures 2 and 3. On the first of these we see that the etching figures on the lower and upper basis are directed opposite to each other. When etching figures are made upon a crystal with rhombohedral faces we see that the sides of the triangle produced by etching are not quite parallel to the edges between с {0001} and и {1012} but 100 are turned about 10° from that direction, to the right or to the left on the two opposite faces of c{0001}. This turning is distinctly shown on Fig. 3 where the directions of the edges (0001) : (1012) are clearly represented by the rays of the per- cussion figure. From this phenomenon it may be seen that this gyrolite belongs to a tetartohedral class, either the trapezohedral or the rhombohedral, and from the above named fact that the figures on the two basal planes are orientated in absolutely opposite direc- tions one may conclude Fig.3.

BE EDEN Physical properties. The cleavage along с{0001} is very strong so that gyrolite in that respect takes a place between gypsum and mica; the cleavage folia are almost perfectly ine- lastic and break very easily into pieces of quite irregular form; in that respect there is a small difference between the mineral from Niakornat and other forms of gyrolite which are, as a rule, somewhat flexible. A fine percussion figure can readily be made with the apparatus described by К. J. V. Sreensrrup !) and consists of a six-rayed star, a part of which is seen on figure 3. The lustre of e {0001} is strong pearly, of the other faces vitreous. The colour is on the fresh crystals grayish or silvery white, on the somewhat altered crystals yellowish white. The purest crystals are perfectly transparent, but mostly they are somewhat dull and, seen under the microscope, traversed by numerous stripes which are curved and pass in all directions 1) Geol. Foren. Fôrh., Stockholm, 10, 1888, p. 113. 101 quite irregularly; so far as can be seen because of their small- ness, they consist of fluid inclusions. The specific gravity has been determined by Thoulets solution; for the purest pieces it is 2'578, while it decreases gradually with the increasing quantity of the above named inclusions; for [one of the more impure pieces it has been determined at 2°463. Gyrolite is, as stated by Descroizeavx') optically negative. | have succeeded in determining the indices of refraction by the total reflectometer, using a very even face of с {0001}; the boundary lines were quite sharp and distinct; I have found: Е бо: = — 11-5590. For the analysis I have selected cleavage pieces of the most perfect transparency; as the mineral is always overgrown with wery small crystals of calcite I have washed it with dilute acetic acid. The analysis was made by cand. polyt. Car. Curi- STENSEN With the following result: Quotients. Theor. I. Theor. IL. SiO, 54-83 0-914 56:42 55-28 Al,O, 458 0:045 4°56 CaO 3115 0:556 3511 31-06 Na,O 174 0-028 H,O 814 0°452 8-47 9-10 Total 100°44. Of the water 2°45 pCt. goes away by heating to 100°; по trace of fluorine is found. As will be seen the quantities of the different constituents do not stand in any simple relation to each other. The com- mon formula for gyrolite, 3 H,O, 2 CaO, 3 SiO,, cannot be adopted here, as the quantity of water is but half so large as required. What part the alumina plays is not easy to see; it cannot, I think, belong to any foreign mineral e.g. feldspar as ANR.) 13, 1867! 102 no trace of any such impurity is to be seen on a micro- scopical examination of the analysed substance, possibly a small amount of kaolin or bauxite could conceal itself amongst the gyrolite, though I do not think it very probable; I have, however calculated the theoretical value (see above No. II) for a mixture of 11°55 pCt. kaolin and 88°45 pCt. gyrolite of the composition 350.5, 2 CaO, 1/2 H,0. On the other side, when the A/,O, is added to the CaO and Na,O, the ratio between the bases and the silica will be a little greater than 2:3; I have, also, calculated the theoretical value (see No. I) for the composition 3505, 2Ca0, 11/2 H,O; we see that these values agree tolerably well with those found, and the last named formula thus most probably represents the com- position of the mineral. As one third of the water goes away at 100° it must be assumed to be water of crystallization and we thus have the following formula for this gyrolite: H, Ca, (StO3), + 4/2 H,O with a small part of the Ca replaced by Na or Al. Before the blowpipe the gyrolite from Niakornat exfoliates and fuses rather easily (fusibility 3'/2) to a white enamel. The same I have found to be the case with the mineral from all other localities including the original from Storr so that the statement commonly found in all handbooks that the mineral fuses with difficulty is, according to my experience, not quite exact. The consideration of the relation between gyrolite and other minerals | shall defer until | have mentioned the mineral from other localities. II. Gyrolite from other Greenland localities. 1. Iglorsuit on Ubekendt @ (Unknown Island), district of Umanak. Here the gyrolite was collected by К. J. V. Steenstrup and is found in cavities with. saponite 103 and apophyllite; the saponite is the first formed mineral but is only found in some places as small spots on the walls of the cavity; the gyrolite forms a stratum, whose thickness varies from !/2 to 2 cm, and upon that stratum the apophyllite is found as rather large (1—2 cm) cubelike crystals, which quite fill up all the spaces between the gyrolite so that freely developed crystals of that mineral are not to be found. The gyrolite, itself, is as usual crystallized in foliated masses ar- ranged rather irregularly; the surfaces of the cleavage folia are rather strongly curved in all directions. I have not succeeded in producing percussion or etching figures upon them; the specific gravity of the purest material is 2°446. 2. Nusak, on the southside of the peninsula of Nug- suak, the district of Ritenbenk. The specimens are col- lected by Risk and the rock seems to be a breccia with numerous cavities in which are found: (1) a radiated columnar mineral pro- bably scolecite in the form of globular masses of a diameter up to 2 cm, (2) gyrolite forming a stratum of 1 to 3 cm thickness and (3) small grains of quartz of quite irregular form implanted upon the gyrolite and probably younger than this mineral; the gyrolite is crystallized in radiating foliated aggregations and it is possible to cleave out quite regular and even folia of a diameter up to I cm; crystalline faces are not found. Percus- sion figures cannot be made and the etching figures, produced by hydrofluoric acid, are quite marked but of a rounded, almost circular, form. The specific gravity is 2'412. 3. Niakornarsuk, near the foregoing place. From here we have a small specimen collected by Sreensrrur with a single cavity (6 cm) the walls of which are covered with а thin (1—2 mm) stratum of thomsonite arranged in globular masses as is commonly the case; upon that mineral saponite or gyrolite is found, where they are found together the gyrolite is the younger of the two. Upon all the three other minerals are implanted flat crystals of apophyllite (see the figure 101 in 104 Mineralogia Groenlandica) which, however, do not cover them altogether. The gyrolite has the ordinary shape of small (1—3 mm) radiating tables which are partly freely protruding in the cavity; the cleavage folia which can be formed are very uneven and small and I have not tried to produce percussion or etching figures; on a microscopical examination it will be seen that their interior is very impure. Under the circum- stances the specific gravity can have no very exact value; for one of the purest pieces I have found 2'383. 4. Iganek, on the northside of Disco, distriet of Ri- tenbenk. Here Sreexsrru has found some small cavities (8 to 10 cm in diameter) the walls of which are covered with a thin (c. 1 mm) layer of thomsonite, on which is a quite un- interrupted layer (3 mm) of gyrolite; this mineral is in it turn, partly covered with cubelike crystals of apophylite; in a single place, too, there are found small botryoideal masses with ex- ceedingly small crystals of calcite. A part of the gyrolite freely protrudes in the cavities as small crystal tables which are so much altered that they have no distinct crystalline faces. The cleavage folia of the gyrolite are rather irregular and curved and it is not possible to produce percussion and etching figures upon them. The specific gravity of the purest variety is 2'387. 5. The distriet of Ritenbenk without more exact indica- tion of the locality (collected by Ring). The gyrolite is in cavities of a diameter up to 5 cm, without surrounding rock. Ощег- most in the cavities there is mostly a thin layer of saponite whereafter follows another thin layer (с. 1 mm) of a mineral which has much resemblance to gyrolite; as it is, however optically biaxial, it is more probably thomsonite. Next follows a layer (c. 5 mm) of a fine-grained or somewhat fibrous snow- white substance which I cannot more exactly determine, and thereafter a layer, of almost the same thickness, of gyrolite; later formed zeolites are not found here but the gyrolite is covered with some very small calcite crystals without distinct 105 form. The gyrolite is partly protruding in the innermost cavity as small crystal tables without determinable faces. The cleavage folia of the gyrolite are rather even and etching figures can be formed upon them of a quite rounded shape; the substance is rather impure and the specific gravity is 2'383. 6. Ivnarsuit (Skarvefjeld) and Karartut on the south side of Disco, district of Godhavn. Here have at very different times, been collected some specimens of the mineral, which show so much resemblance to each other that they must be considered as having come from the same place, the two loca- lities being, in fact, very close together. The gyrolite is found in cavities in dolerite, the diameter of the cavities is up to 1 dm. The first formed mineral is natrolite, formed as very regular radiating masses from which fine needles protrude through the other minerals. Upon the natrolite the gyrolite is formed, covering directly the walls of the cavities where the natrolite is wanting. Innermost there are large (2—3 cm) crystals of apophyllite implanted on the two first formed mi- nerals. The gyrolite has the form of fine spherical masses (с. 1 cm in diameter) sometimes traversed by natrolite needles but mostly very pure; crystalline faces are found on the out- side but they are too small to be determined. The cleavage folia are somewhat curved and it is not possible to produce regular percussion figures проп! Фет; etching figures of a quite circular form can be produced with hydrofluoric acid. The specific gravity, which, owing to the purity of the mineral, can be determined very exactly, is 2°418. Optically this gyrolite is sometimes feebly biaxial, the axial angle, 2 E, going up tonc. 10°. 7. Karusuit in Disco-Fjord, district of Godhavn. The gyrolite from here, collected by Rısk, is one of the finest and best developed examples of the mineral. The first formed mi- neral is in some places radiating fibrous masses, perhaps me- solite, in other places a rather hard, white, quite homogeneous, 106 almost opal-like substance; in general the gyrolite itself covers the walls of the cavities. The inner space of the cavities is sometimes filled up by apophyllite in large-grained masses, sometimes the gyrolite is covered by a very thin (с. 0:1 mm.) layer of an opaque yellow substance, and when this is removed crystalline faces can be seen. The gyrolite itself has the com- mon structure of foliated masses, the single folia reaching the diameter of I cm, it seems to be very pure and has a fine pearly lustre. The terminal faces are very small and curved; in the goniometer they can however be determined as the fundamental rhombohedron > {1011}. The faces are very im- perfectly developed; the base is bright and shining but highly curved so that it gives no single signal in the goniometer; the faces of r {1011} are more even but very small and their re- flexions of course very weak; for the angles I have got the following values: Average ео Number of Calculated value arlations measurements value r:c = (1011):(0001) = 65° 55’ 64°06’-67°08 4 65° 57’ The average value and the variations agree very well with those of the mineral from Niakornat; no trace of the rhom- bohedron u {1012} is found. The physical properties are the same as from the foregoing locality, the gyrolite here being also, in many cases, optically biaxial. The specific gravity is 2417. 8. Another gyrolite from Disco-Fjord without more spe- cific locality shows a very great similarity to the preceding and may, perhaps, originate from the same place. III. General remarks. As will be seen from the foregoing most of the Greenland gyrolites show, in almost all respects, very small variations, and the same is according to what I have seen in the literature and for a great part confirmed by my own observations, the case with the gyrolite from all other countries. The only ex- as 107 ception is the mineral from Niakornat, wich possesses so many particular properties that it may, perhaps, be somewhat doubtful if it in reality belongs to gyrolite. In the following remarks | shall point out the resemblances and the differences between the gyrolite from Niakornat and other gyrolites. The occurrence is very uniform and characteristic. The mineral is always found in cavities in basalt or basaltic tufa; the first formed minerals associated with it in these cavities is for the Greenland localities one of the zeolites natrolite, meso- lite, scolecite or thomsonite and in some cases saponite alone or together with one of the named zeolites; the last formed mineral ist mostly apophyllite and in a few cases calcite or quarz. For the Scottish gyrolites Currie has given me the following scheme where is collected all what is known about the mineral associations 4): 1. Faroelite-Scolecite-Gyrolite (Treshnish Islands). 2.

Mag. 5, 1882, p. 4 108 From other places in the world very little is recorded about gyrolite; at Sundelaget in the F&röes, it is found’) with apophyllite superimposed and the same is the case with the gyrolite from New Almaden, California’), while it in Nova Scotia?) is stated to be younger than the apophyllite. As a rule, however, we find that the succession of minerals is the following. 1. One of the zeolites: natrolite, mesolite, scolecite or thomsonite. 2. Gyrolite. 3. Apophyllite. This association seems very difficult, if not impossible, to explain; it is highly surprising that the zeolites of the group 1 which contain the most alumina of all zeolites are found to- gether with the gyrolite and the apophyllite which contain little or no alumina while all the other zeolites very rarely occur with them, further, the order of formation is very obvious when we take into consideration the amount of lime in the three groups; it is for the first group O—14 pCt., for the gyrolite 30—33 and for the apophyllite c. 25 pCt. For the sake of comparison I give the composition of the three groups in the following scheme: 1. 2» 3.

The crystalline form is only known for the gyrolite from Niakornat and Karusuit; it is in both cases the same, with the one exception that the crystals from Niakornat sometimes have the rhombohedron u {1012} which is entirely wanting on the crystals from the other locality. The form of the aggre- gations and the common habit of the mineral is also almost the same in all known gyrolites. On the other side there are in the following respects very marked differences between the gyrolite from Niakornat and that from other localities: i 1. The etching and percussion figures can be made very easily upon the gyrolite from Niakornat while both are very imperfect on all other gyrolites or are not formed at all. 2. The specific gravity is for the pure gyrolite from Nia- kornat 2'578; in other gyrolites it varies from 2°383 to 2'446. 3. The composition.

XXXIV. 8 110 As will be seen the greatest difference consists in the amount of water which is much smaller in the gyrolite from Niakornat than in the others; accordingly the amount of the other constituents must, in general, be somewhat larger; an- other difference, which however cannot be considered as very essential, is that comparatively much of the CaO is replaced Бу Al,O, and Na,O. The formule of the minerals can, quite exactly, be expressed as follows: I Gyrolite from Niakornat 3 S10,, 2 CaO, 14/2 H,0, Gyrolite from Skye, N. Scotia, N. Almaden 3 Si0,, 2 CaO, 21/2—3 H,01, Gyrolite from Brazil and Fort Point 3010, SAC AO KDE ASE 0 As long as we have not found transitions between the different forms it is not possible exactly to decide if they are in reality the same mineral; I find it very probable that the gyrolite from Niakornat represents the fresh state of the mineral and that all the other gyrolites are altered by assorption of water, by that alteration the specific gravity must, of course, be lowered; the crystalline structure has been so much de- formed that the etching and percussion figures cannot be made in the altered mineral, while the optical properties seem to be almost the same in both varieties, all forms of gyrolite being optically negative and either perfectly uniaxial or occa- sionally weakly biaxial. It is true that no similar alteration in other minerals seems to be known; but the great similarity between the different varieties of gyrolite in respect of occur- rence and erystalline form seems to show that they belong to the same mineral species. 1) In the case of the mineral from Skye, ANDERSEN observed already in 1857 that onethird of the water goes off at 100°. The formula there- fore for the Skye mineral — and presumably for other gyrolites with the same proportion of H,O — should empirically be written H,Ca, Si,0,, + H,O. 111 Relations to zeophyllite!) and other minerals. The only mineral to which gyrolite is somewhat closely related is, as far as I can see, the zeophyllite from Grosz- Priesen?) and Alter Berg) in Bohemia. I shall in the following give a short account of the properties of that mineral, as far as they can contribute to clear up the relation between it and gyrolite. The succession of minerals is very different in the two zeophyllite localities; at Grosz-Priesen it overlies natrolite and at Alter Berg it overlies calcite or hyalite and apophyllite and is overlaid by hyalite; we thus see, that the occurrence of zeophyllite is not quite similar to that of gyrolite, but as the last named mineral varies somewhat in that respect it is not possible to regard that fact as conclusive. The crystalline form is by Perxax described as rhombo- hedral with the base, a prism and a rhombohedron forming an angle of almost 78° with the base; Cornu has not more closely examined the mineral in that respect, upon a specimen from Alter Berg in the Museum of Copenhagen I have, however, found quite the same form. As the base is very badly developed I have measured the angle between the prism (of second order) and the rhombohedron and determined it to 31° 45’ as a mean of 6 values varying from), 31° 15” 10 32° 05° ‘from this the angle between the rhombohedron and the base is calculated to be 79° 05’, and if we assume that the rhom- bohedron is s{0221} we get the axial ratio for the zeophyllite : C= 22451 while for the gyrolite: с = 1°9360. As the measurement of the angles are for neither of the 1) This relation is mentioned by Cornu: Centralbl. f. Min. 1906, p. 80. 2) PELIKAN: Sitzb. 4. К. Akad. 4. Wiss.

The common combination of the zeophyllite, viz c {0001}, a {1120} and s{0221} is represented on figure 4. The etching figures ue a are described by РЕ- [5] le] LIKAN and show that the zeophyllite is te- tartohedral; I think it most probable that it belongs to the same class as gyrolite, Fig. 4 Zeophyllite, Alter Berg, Bohemia. viz. the rhombohedral. The aggregations, the cleavage and the common habit of the two minerals are quite similar; the optical properties are almost the same too, the zeophyllite being negative but exhi- biting more optical anomalies than the gyrolite; the index of refraction is for the zeophyllite somewhat smaller the w being determined by Cornu at 1°545. The specific gravity is for the pure zeophyllite 2°748— 2°765 while it for the gyrolite from - Niakornat is 2°578. The composition is given by Perikan for the zeophyllite: DO баре for the gyrolite from Niakornat it is: SiO SACHE, so that we find in that respect a great difference between the: two minerals. Although there are many similarities between the zeo- phyllite and the gyrolite they must be considered, as two well defined minerals which are, most probably, isomorphous and form a very interesting group of the calcium zeolites; un- fortunately these are, with the exception of apophyllite, very imperfectly known and consequently it is difficult if not quite impossible to point out the relations between them. Some of them come very near to gyrolite in composition and are, per- haps, only a very fine grained form of that mineral. The most 113 interesting of these minerals seems to be the centrallassite !) which in physical properties viz. laminar structure and strong pearly lustre, seems to be identical with the gyrolite and in respect to specific gravity (= 2°45—2°46) and chemical com- position directly to form a transition between the two forms of gyrolite. Most of the analyses, to the sure, contain more SiO, than the gyrotite, but one of them has only 5472 р. ct. Si0, and perhaps the other may be impure from some free silica as is assumed to be the case with the variety of cen- trallassite named cyanolite; in other respects (47,0, 1—2 р. ct. and H,O с. 11°5 р. ct.) the mineral will be seen to take a position between the gyrolite from Niakornat and the other gyrolites. Another mineral which is very nearly related to gyrolite is tobermorite*); in physical respects it is so fine grained an aggregate that cleavage etc. cannot be observed; the specific gravity is 2'423. The analyses show that the amount of 50, (46°51—46°62 р. сё.) is smaller than in gyrolite, but in respect to CaO, Al,O, and H,O it closely resembles centrallassite. Okenite does not stand very far from gyrolite in com- position, but here the physical properties show that the two minerals cannot be very nearly related to each other. The rest of the calcium zeolites, viz. the chalcomorphite, the plombierite, the louisite and the zonotlite, differ in com- position very much from gyrolite; chalcomorphite*) is found as very small hexagonal crystals with the axis с = 1°9091 (it is almost the same as in gyrolite); as the mineral is, however, holohedric and the cleavage parallel to the base is only de- scribed as ‘distinct” it is most probable that the similarity of the axial ratios must be considered as quite accidental. 1) How: Ed. п. phil.

After the above paper was written I received from Cornu) a very interesting treatise upon gyrolite and related minerals. According to this the mineral from Niakornat is a new mineral species and it is named reyerite and besides the dif- ferences between it and gyrolite, which I had already found, there is also stated to be a small difference in respect to the index of refraction, the w of the gyrolite being determined at 1-54—1°55 while for the reyerite it is 1°5645. The reyerite is, stated to originate from Disco as well as from Niakornat; it may, however, be the same locality as Niakornat was formerly described as a locality upon Disco, as we have seen above. As the paper by Cornu is stated to be a preliminary one a more exact description of the specimens will, perhaps, clear up this point. As Greenland localities for gyrolite there are named: 1. Korosoak (= Kororsuak near Godhavn): from that place I have found no gyrolite; Cornu describes three different varieties all occurring together with apophyllite partly older and partly younger than that mineral. 2. Karatut near Godhavn (= Karartut, see above p. 105) here the gyrolite is described as implanted upon apo- phyllite, while, on the specimen examined by me it is distinctly older than that mineral; the form described as small spheres, also shows that the specimens are quite different from each other. 3. Niakornak. From that locality I have found no gyrolite besides the above named which by Cornu has been termed reyerite. 1) Tschermaks min. u. рег. Mitth. 25, 1907, Heft 6. Geologiske og antikvariske Iagttagelser 1 Julianehaab Distrikt. Af K. J. V. Steenstrup. 1909; Paa forskellige Rejser, i Aarene 1874, 76, 77, 88 og 99, har jeg haft Lejlighed til at undersøge Fjordene Tunugdliarfik, Kangerdluarsuk og Igaliko ved Julianehaab. Hensigten med disse Rejser var dels en Indsamling af de sjeldne Mineralier, der der forekomme, dels at skaffe en almindelig Oversigt over de geologiske Forhold. Fra Rejsen i 1876 foreligger en til Professor Johnstrup indgiven forelebig Beretning, der blev trykt uden hans og mit Viden, da den, som Bilag var indsendt til Rigsdagen!); og i 2det Hefte af «Meddelelser om Gronland» findes et geologisk Kort over denne Egn med Forklaring. | 1877 besogte jeg under et kortere Ophold igen denne Egn; og, da alle Bjergartsproverne og den storste, om end ikke just den vesentligste Del af de i Aarene 1876 og 77 indsamlede Mineraler vare gaaede til Grunde ved Christianborgs Brand i 1884, besluttedes det i 1888 at jeg igen skulde rejse derop for at forsøge paa at erstatte det tabte. Paa den Tid var Spergs- maalet om Gasglodelyset sterkt fremme og Opmerksomheden derved henvendt paa Eudialyten paa Grund af dens Indhold af Zirkonsyre. Kryolith-Mine- og Handels-Selskabet sogte saa Indenrigsministeriet om Tilladelse til at lade indsamle og bryde et storre Parti Eudialyt for dermed at anstille Forsog. Da jeg den Gang, paa Grund af mine tidligere Undersogelser, vel om- trent var den eneste der vidste nogen Besked om den Maade, hvorpaa Eudialyten forekom, henvendte Kryolithselskabet sig til 1) Tillæg В Ш Rigsdagstidenden for 1877 —78. 118 Professor Johnstrup, der dengang var Formand i Kommis- sionen for Grønlands geologiske Undersøgelse, og bad om jeg maatte lede den Expedition det agtede at udsende. — Dette gik han med Glæde ind paa, da Kommissionens Opgave jo ikke alene var videnskabelig at undersoge Gronland men ogsaa at fremdrage de Naturprodukter, der kunne have teknisk Betyd- ning, og derved mulig blive en Indtegtskilde for Landet, som Kryolithen. — Vel vidste jeg nok hvor Eudialyten skulde soges, men jeg havde dog ingen Anelse om i hvor stor en Mengde, selv en overfladisk og loselig Indsamling kunde skaffe tilveje, hvorfor jeg, da Selskabet spurgte mig om hvormeget jeg troede en halv Snes Arbejdere i en halv Snes Dage kunde indsamle, ikke turde love mere end nogle faa Tusinde Kilo. Resultatet var imidlertid, at denne første Indsamling indbragte c. 15000 Kilo, hvoraf omtrent Halvdelen kunde anses for ren Eudialyt. Uagtet det hed sig, at Eudialyten var usælgelig og at Sel- skabet laa inde med hele Lageret, saaledes fortalte Professor Thomsen mig, at de vel havde solgt et Parti, men faaet det tilbage, da vedkommende Fabrik ikke vilde anerkende at det indeholdt den Zirkonsyremængde der var forudsat; — saa be- sluttede Kryolithselskabet dog igen i 1899, atter efter indhentet Tilladelse, at lade foretage en lignende men noget større Ind- samling af Eudialyt, og henvendte sig saa igen til mig om at lede Expeditionen. Uagtet jeg havde besluttet ikke oftere at rejse til Grønland, da jeg paa min sidste Rejse i 1898 til Nord- Grønland havde følt at jeg ikke længere kunde taale de idelige Bjergbestigninger der vare forbundne dermed, saa kunde jeg dog ikke modstaa Professor Jul. Thomsens elskværdige Op- fordring, hvorved jeg jo ogsaa endnu en Gang vilde faa Lej- lighed til at færdes i denne, saavel i geologisk som i antikvarisk Retning lige interessante Egn. — Resultatet var, at der denne Gang hjemførtes с. 44000 Kilo uren Eudialyt. Dette Minerals Forekomst vil senere i denne Beretning blive omtalt, hvorimod selve den Maade, hvorpaa Eudialyten efter min Anvisning ind- 119 samledes og bredes ikke her omtales paa Grund af et ud- trykkeligt udtalt Onske af Kryolithselskabets nuverende ledende Direktor Dr. phil. H. Topsoe. For Oversigtens Skyld ere mine lagttagelser fra de for- skellige Rejser samlede i folgende 3 Afsnit: 1) De geologiske, særlig den gamle rede Sandsten. 2) Mineralogiske lagttagelser og Indsamlinger, og 3) Antikvariske lagttagelser. 1. Den rede Sandsten. Allerede Hans Egede blev paa sin Rejse i 1723 for at finde Osterbygden, af Grønlænderne gjort opmærksom paa, at der inde i Fjorden Tunugdliarfik fandtes «en slags brunrød Farve, desligeste rede Stene med hvide Spætter ид» 1); først Peder Olsen Walloe paa sin Rejse til Ostkysten i 1751, stiftede nærmere Bekendtskab med den røde Sandsten, da han den 12te September s. A. kom Ш Sidlisit: «her blev mig anvist 2 Bjerge ner hos hinanden, som havde god Forraad af bruun- red Farve; men i Udkanten af den ene var en Vinkel som be- stod af kolorede Stene, годе med hvide Pletter og derfor kunde lade sig udklove i store og smaa Fliser, saa meget man lystede». Hertil fojer Otto Fabricius: Jeg besidder en Ргоуе af disse Stene som til Nod kunne bruges som Hvedsestene, og deraf har vel Stedet sit Navn: Sidlisit, betyder paa gronlandsk Hvesse- sten”). Ogsaa Arctander, paa sin Rejse i 1777 besagte efter Gronlendernes Anvisning dette Sted, ligesom han ogsaa efter deres Anvisning besogte Stedet ved Ipiutak, hvor de mange Kvartskrystaller findes >). Giesecke omtaler paa sine Rejser i 1806 og 1809 flere Steder, hvor den røde Sandsten forekommer i denne Egn, og 1) Omst. og udførl. Relation ang. den grønl. Mission. Kbhvn. 1738. S.115. ?)

Dog gaar han vel vidt, naar han tilfojer: die Oberfläche des Gebirges selbst hat durchaus ein verbranntes Aussehen!). I sin Af- handling: «Greenland» i Brewsters «The Edinburgh Ency- clopædie» kalder han Sandstenen Old red Sandstone?). Dr. C. Pingel besagte i 1828 Igaliko og har i Vidensk. Selsk. Skrifter”) givet en Beskrivelse af Sandstenen og de den gennembrydende Porphyrganges Optræden. Paa Grund af dette Forhold mellem den rode Sandsten og Porphyrgangene henforer han den forste til Tyskernes: Rothes Todtes Liegende, altsaa til den Permiske Formation. Da hans Undersegelser kun strakte sig til Igalikos allernermeste Omegn og kun til en ringe Hojde over Vandfladen, c. 200 m. have hans Inddelinger af Sandsten- lagene og Porphyrgangene ikke den almindelige Betydning, som man efter hans Fremstilling skulde tro. Paa Holms og mit Kort fra 18767) har jeg angivet den rede Sandstens Grense, saavidt jeg efter dette ene Aars Under- sogelser kunde overse Forholdene, og mine senere Undersogelser have ikke i nogen vesentlig Grad forandret noget deri, saa jeg har ikke anset det for nødvendigt at tegne et nyt Kort; og saa- lenge ikke et mere detailleret Kort foreligger, tror jeg heller ikke at det behoves. Grenserne mod Fjordene ere jo angivne med den Nojagtighed, hvormed disse ere aflagte og Grænserne paa Land er det umuligt at angive med nogen Nojagtighed, saalenge Terrainforholdene der kun ere saa lost skitserede, som det for Øjeblikket er Tilfældet. Som det ses af Kortet er det i det Indre af Halveen, 1) Dagbog 18|з 1806. *) Optrykt af Johnstrup sammen med Gieseckes Dagbog S. 343. 3) Om den af Porphyrgange gennembrudte rede Sandsten i det sydlige Grønland i X.

Tavel- 121 mellem Sermilik og Tunugdliarfik, at den rode Sandsten har sin største Udbredelse, medens den de andre Steder hvor den forekommer, som ved Igaliko og i Bunden af Kangerdluarsuk kun optreder som mindre Partier, der paa Grund af serlig Fasthed eller paa Grund af Terrainforholdene ere blevne delvist skaanede for Iserosionen. Alle Isfurerne paa Klipperne vise hen til, at Isbevegelsen er kommen fra Indlandet, fra NO., og Isfurerne paa Toppen af Nunasarnausak (755 M.) og paa Toppen af Nulupsaxak (812 m.) vise, at Isens Megtighed maa have været saa stor, at selv saadanne Fjeldtoppe ikke have formaaet at paavirke Isstrommens Retning; den er gaaet hen over dem, som om det var uvesentlige Hindringer. I 1877 besteg da- verende Lojtnant J. A. D. Jensen og jeg en af Ilimausaks hojeste Toppe (1376 m.), hvor der dog, vistnok paa Grund af Bjergartens sprengte Beskaffenhed, ingen Isfurer saas, men derimod fandtes der indtil en Højde af с. 1200 m., en Mængde afrundede Sten af forskellige Bjergarter. Selve Торреп er Diabas 1. Det maa altsaa have været en mægtig Isstrom, der i sin Tid har gaaet hen over Narssak og Julianehaabs Halvoerne; hvor kun enkelte Fjeldtoppe som Ilimausaks og Redekammens’”) ragende op derover. Det er derfor naturligt, at den rede Stand- sten, med de underordnede Lag af Diabas, flere Steder ere nesten fuldstendig borteroderede, som i Lavningerne mellem Sermilik og Tunugdliarfik og paa Overberestedet ved Igaliko.

Foto- grafierne paa Tavlerne XIX kunne maaske give et Begreb om denne Egns Goldhed. Her i denne, over store Strækninger til dybe Gruslag forandrede Bjergart, findes Eudialyten, dels ud- fyldende Spalter i de haardere Partier, dels liggende løse, som oftest i flade eller elliptiske Partier, der kunne naa en Vægt af over 50 Kilo og som for en Del ere Rester af Pegmatitgangene. 1) I Mineralogisk Museums Forhal findes en udmærket Prøve paa et saadant elliptisk Lag. ?) «Fox» kastede her en Del af sin Ballast over Bord, hvilket bemærkes for at forebygge Misforstaaelse; thi denne Ballast bestod for en væsentlig Del af Kryolith og de sammen med denne forekommende Mineralier, 134 Forgrunden i det averste Billede paa Tavle XX viser et saadant Parti, hvor Overfladen af den faststaaende Sodalithsyenit næsten er skjult af Forvittringsmaterialet, i og paa hvilket sidste der ег fundet løse Eudialytstykker til en samlet Vægt af mange hun- drede Kilo. Paa Kortskitsen Fig. 2 ere Eudialytlagene betegnede ved en tyk sort Streg, medens de Strækninger, hvor de lese Eudialytstykker ere samlede, ere betegnede ved Kors.

Gangen gaar skraat ned under Vandfladen og er ved Hojvande nesten dækket; medens den ved Lavvande er blottet i en Lengde af c. 12 m. I nederste Billede paa Tavle XX, ses det overste af denne Gang, hvor den forøvrigt næsten er svunden ind til en Ubetydelighed.') Denne Gang har ydet flere Tusinde Kilo Eudialyt. Circa 5000 Kilo ydede fremdeles et Lag i Bunden af Fjorden, der laa i en Afstand af са. 900 m. og i en Hojde af 200 m. over Vandfladen. Ydede end disse og et Par andre, men mindre Gange og Lag en betydelig Mengde Eudialyt, saa vandtes dog den langt over- vejende Del af de hidtil hjembragte ca. 55000 Kilo ved paa Rouserne at indsamle lose Stykker. Mange af disse sidste bestode naturligvis langt fra af rent Mineral; men Regelen var, at intet Stykke maatte medtages, hvori Eudialyten udgjorde mindre end Halvdelen, efter at de vedhængende Mineralier vare fjernede ved Hammeren. Arbejdet er jo i egentligste Forstand Rovdrift; thi der toges alt hvad der fandtes, og da de enkelte Pegmatitgange i Reglen snart kile ud, kan et planlagt Mine- arbejde ikke anlegges paa et bestemt Sted. Da Kryolith-Selskabet i 1888 overdrog mig Ledelsen af Indsamlingen af Eudialyt og i den Anledning spurgte mig om, hvormeget jeg mente at der kunde skaffes til Veje, turde jeg 1) Dette Billede, der er taget i 1899, viser ogsaa en Del af Tang- og Balan- randen.

Vi toge alt, hvad vi saa, saa theoretisk skulde der ikke vere stort tilbage, og dog naaede vi, som nævnt, i 1899 endnu at faa indsamlet ca. 44000 Kilo. Uagtet vi ogsaa da toge alt, hvad vi saa, saa tvivler jeg dog ikke om, at der jo nok endnu vil kunne samles adskillige Tusinde Kilo; men, det er jo klart, at saaledes kan det ikke blive ved, engang maa Endialytmengden ved en saadan overfladisk Indvinding hore op, eller i det mindste kun forekomme i en saa ringe Mengde, at det ikke kan betale de ikke ubetydelige Omkostninger, der ere forbundne dermed. Jeg skal ikke her komme ind paa Sporgsmaalet, om ikke Ind- vindingen af Eudialyt kunde foretages paa en billigere Maade end den hidtil anvendte. Skulde det vise sig, hvad der jo destoverre ikke for Qje- blikket skal vere Udsigt til, at Eudialyten har en Fremtid for sig i teknisk Henseende, bliver Sporgsmaalet: findes der ikke andre Steder i Sodalithsyeniten, hvor Eudialyten optreder i lignende Mengde som i Kangerdluarsuk; thi som enkelte Kry- staller eller som nevestore Partier findes det, snart sagt, overalt. Flere Steder kan der uden Tvivl ved nøjere Undersøgelse findes en Del; men det eneste Sted, jeg har set, der saavel i Eudialytmængde som i let Tilgængelighed kommer Bunden af Kangerdluarsuk nær, er Tupersiatsiap ved Naujakasik i Tunugd- liarfik. Her synes tilmed, ligesom i Kangerdluarsuk, at være den Fordel, at et Skib som «Fox» maa kunne ligge dækket mod de fleste Vinde, ligesom ogsaa for Isfjælde og Kalvis fra Sermilik og Koruk.

Fra Teltpladsen og vestefter, henad Najakasik, findes indsprængt og temmelig jævnt fordelt gjennem hele Bjergarten ikke ubetydelige Mængder af Eudialyt; men hvis der skulde vere Tale om at indvinde den her, maatte dette Minerals Verdi stige i en overordentlig Grad. Øst for Teltpladsen og langs Bugtens hele Sydside fore- kommer Eudialyten derimod under fuldstendig lignende Forhold som i Kangerdluarsuk 9: dels som større og mindre lostliggende Blokke og dels paa ЗраНег og i Lag.

Fig. 3. den vestligste af de smaa Elve i Bunden af Bugten, og som er let kjendelig derved, at den danner et smukt lille Vandfald, et ca. 30 cm. megtigt Lag af meget rent Eudialyt, der, saavidt det paa den stejle, af lost Materiale dekkede Skrent kunde ses, havde en betydelig Udstrækning. Det nederste Fotografi paa Tavle XXI er et Billede af denne stejle Fjældvæg, der danner en Del af Sydsiden af Elvlejet. Det viser Sodalithsyenitens «bænkede» Struktur, og endvidere hvorledes den er gjennem- trængt af mere og mindre lodrette Sletter og Gange. Eudialyt- laget findes enten ved den nederste eller maaske snarere ved den næstnederste af de paa Billedet synlige horizontaie Kløv- 138 ninger. I Elvlejet laa flere, ja endog meget store Blokke af nesten ren Eudialyt. Paa Vestsiden af den neste Elv, den anden, fandtes ligeledes et Eudialytlag, der ikke alene havde en Megtighed som det foregaaende Lag, men som endog var af- dækket paa en større Flade, saa der uden Tvivl den Gang med Lethed kunde have været taget flere tusinde ‚Kilo. Desuden fandtes paa Skraaningerne ved begge Elve en Mengde lose Blokke. | 2. Kvartskrystaller fra Narsasuk. Da jeg i 1888 var ved Igaliko, tilbod Gronlenderne mig en Mengde afbrudte og ufuldstændige Ægirinkrystaller, der kun gjorde sig bemærket ved deres store Mengde. I Begyndelsen tillagde jeg ikke disse Krystaller nogen Betydning; men efterhaanden tiltrak deres store Mængde sig min Opmærksomhed, og paa mit Spørgsmaal om, hvorfra de stammede, nævnede de Narsasuk og pegte henimod Kistefjeldet. Da jeg bad dem vise mig Stedet, førte de mig | hen til et af de sædvanlig grusede Steder, som jeg kendte saa godt fra mine Bestigninger af Kistefjeldet. Deri saa jeg intet paafaldende, og da de fortalte mig, at Krystallerne fandtes ved at gennemsøge Gruset, og jeg efter en kort Afsøgning ingen | fandt, forlod jeg Stedet, da jeg mente, at Fundet af disse Kry- staller, der ganske vist havde et noget forskelligt Udseende fra Ægirinkrystallerne i Kangerdluarsuk, ikke havde nogen særlig videnskabelig Betydning. Da jeg senere kom til Julianehaab, viste Kolonibestyrer Lytzen mig en Del store og smukt udviklede Ægirinkrystaller, som han tilbød Museet. Om de nye Mineralier, som Neptunit о. s. v., som han maaske allerede da, eller i al Fald snart efter sendte til svenske Mineraloger, nævnede han dengang eller senere ikke et Ord. I 1897 undersøgte den svenske Mineralog Gustaf Flink, hvem de lytzenske Samlinger vare komne i Hænde, paa Kommissionens Bekostning Narsasuk og fandt derved mange nye Mineralier, som han har beskrevet i M. o. G. XIV og XXIV. I 1899 besøgte ogsaa jeg igen Stedet. I Mineralogia Groenlandica er Materialet fra denne Indsam- 139 ling medtaget, og jeg skal derfor her kun omtale nogle Kvarts- krystaller, der straks tiltrak sig min Opmerksomhed paa Grund af, at de utvetydigt viste den basiske Flade, der jo horer til en af de storste krystallografiske Sjeldenheder. Tavle XI, Fig. 1 viser en saadan Krystaldruse, der yderst bestaar af 6 symmetrisk sammenvoxede Krystaller, i hvis Indre flere mindre ses og hvoraf de fleste ere forsynede med Basis; der hos dem alle spejle paa én Gang. Ses de under Lupen, iagttager man, at disse Flader ere svagt krummede, saa at de paa Goniometret ikke spejle som én Flade, saa deres Vinkel med Pyramide- fladerne ikke kan maales med Nojagtighed. Endvidere ses det, at disse Basisflader alle have et drueformet chalcedonagtigt Ydre (Fig. 2). Kvartsen i disse Krystaller er i Reglen glasklar, nesten hyalitagtig og spejler med en vandklar Friskhed, der gør, at de se ud, som om de ere slikkede. Ikke alene pau de enkelte, skarpt udpregede Krystaller findes disse ejendommelige Flader; men de findes ogsaa i hele Samlinger paa de uformelige Krystaldruser, som Dr. Flink") har omtalt som den mest almin- delige Form: «namely in individuals that have been so strongly attacked by solvents that one can no longer see whether they were originally idiomorphic crystals or massive lumps. The quartz crystals from Narsarsuk show all the stages of etching, from its appearance as a mere trace to the total obliteration of the original form.» Figurerne 3—5 paa Tavle XI vise de for- skellige Sider paa en saadan «massiv lump», der findes i Dr. Flinks Samling, og som efter hans Formening er fremkommen ved Oplosning, men hvori jeg kun kan se en meget svagt indi- vidueliseret Kvartskrystal, der er sammensat af en Mengde Individer paa en noget lignende, men langt mere kompliceret Maade, end som det ses i Fig. 1, Tavle XI. Fig. 4 paa denne Tavle viser nemlig Prismet med sin horizontale Stribning. Fig. 3 viser en Pyramideflade med sine karakteristiske Figurer 1) M. o. Gr. XXIV, S. 21. 140 og endelig viser Fig. 5 en paa Basis’s Plads værende Overflade, der er sammensat af mange smaa Endeflader (de karakteristiske med Vorterne) i Forbindelse med Tillob til Pyramideflader. Fotografierne vise vel skarpt nok de forskellige Flader; men kun, naar man kan tage disse usedvanlige Krystaller i Haanden og bese dem fra alle Sider, faar man det rette Indtryk af dem. Uagtet Basis er meget almindelig hos hexagonale Krystaller, saa er der jo den Merkelighed ved Kvartsen, at denne Flade kun yderst sjeldent optreder hos dette Mineral, og dertil kan vel kun Grunden vere den, at Kvartsens Sammensetning eller Struktur ikke i Almindelighed er gunstig for denne Flades Fremkomst, og fremkommer den saa som her en enkelt Gang’), forekommer det mig, at det er karakteristiskt at se, hvor ufuld- kommen den er, idet den jo minder om Kvartsens mindre fuld- komne Form: Chalcedonen. Det kan bemerkes, at disse Kvarts- krystaller ere usædvanlig rige paa smukke, skarpt udprægede hule Krystaller, der næsten alle synes at have en ubevægelig Libelle. 3. Kvarts-Pseudomorphoser fra Ivinguit ved Narsak. | 1876 samlede jeg paa dette Sted paa Spalter i en tufagtig Diabasis en stor Mængde Krystaller, der bestode af Kvarts, men som tydelig viste sig at vere Pseudomorphoser efter et eller andet Mineral, hvilket, har det ligesaalidt strax som senere veret muligt at bestemme, og det lykkes vel ogsaa kun, naar der engang findes Rester af det oprindelige Mineral idem. Alle de indsamlede Krystaller gik imidlertid til Grunde ved Christiansborgs Brand; men i 1899, da jeg igen besøgte Stedet, lykkedes det mig at skaffe en ny Samling, dog langt fra saa stor som den forste. Professor Ussing har undersogt disse Krystaller og givet folgende Beskrivelse af dem: «Kvartsseudomorphoserne fra Ivin- guit ved Narsak har et Udseende som gengivet paa hosstaaende 1) Det bemerkes, at det her ikke drejer sig om en enkelt Krystal, men at f Fænomenet er gennemgaaende hos en stor Del af de fundne Krystaller. 141 Fig. 4. I Storrelse naar de som oftest c. 2 cm, enkelte af Krystallerne endog indtil 6 cm. De optreder ofte som hele Krystalblokke af tilnermelsesvis parallelt stillede Individer (se Fotografiet); ved denne Anordning i Forbindelse med Krystal- lernes Habitus fremkommer ofte en overfladisk Lighed med de i alle Samlinger udbredte Pragtstykker af krystal- linsk Svovl fra Sicilien. Efter de maalte Vink- ler har jeg ikke kunnet identificere disse Pseudo- morphoser med nogen i Mineralverdenen almin- delig forekommende Kry- stalform, og da Fladernes Fig. 4.

Beskaffenhed ikke tillader nejagtige Maalinger, og saaledes heller ikke Sammenligninger med sjældnere Former, har For- soget paa, gennem Formen at udfinde det oprindelige Mineral maattet opgives. Her skal derfor kun anfores en ganske kort Beskrivelse: Pseudomorphosernes Habitus ег rhombisk. Vinklerne maaltes med Anlægsgoniometret og lod sig bestemme med en Nojagtighed paa 1 à 2°; der kunde ikke kon- stateres nogen Afvigelse fra den rhombiske Symmetri, men paa Fig. 5. Grund af den nævnte Usikkerhed i Maalingerne maa man regne med den Mulighed, at Krystallerne i Virkeligheden tilhører det monokline eller trikline System. Naar Formen betragtes som rhombisk og opstilles som Figur 5 viser, bliver de tilstedeværende Former at betegne som rhombisk Dobbeltpyramide, Basis og andet Endefladepar eller (111). (001) . (010).

Iblandt de Mineralier, der oftest er nævnet i Forbindelse med Spergsmaalet om Kryolithens Dannelse, hører Topasen; men uagtet jeg ofte, under mine Besog ved Ivigtut, har tænkt paa, om dog ikke dette Mineral skulde findes der, saa har jeg dog aldrig fundet noget, der kunde minde derom. Ved Gen- nemsyn i Fjor af nogle Mineralprover, jeg i 1899 havde haft med fra Ivigtut, men som vare blevne henstaaende ubestemte!), var ogsaa et storre Stykke Kryolith, der var gennemtrengt af en flere Centimeter bred Zone af sammenklumpede smaa straalet- krystallinske Korn, som jeg, da jeg tog det, tænkte maatte vere enten en Kvarts- eller Feldspathmasse. Ved nu at tage det frem til nermere Undersogelse fandtes det let, at det ikke var nogen af Delene. Det var mathvidt, med et svagt gulligt Sker, og haardt, saa det ridsede Kvarts. Vegtfylden var, efter at Kryo- lithen var fjernet ved Kogning med Kloralluminium, 3,51. Ved svag Glodning blev det rosenredt. Efter Hr. Cand. polyt. Chr. Christensens Analyse er Sammensætningen folgende: SiO, == 30,02 Al,0, = 58,51 F — 19,53 107,06 — Ш — = 7,80 99,26 1) [blandt de Praver af Kryolithmineralier, jeg i 1899 havde hjem med fra Ivigtut, har Docent Boggild fundet et mindre Stykke Kryolitionit, som 143 Mineralet er altsaa Topas, hvad hverken Lysbrydningen eller Dobbeltbrydningen modsiger. Da Direktor Jarl paa «Øresund» saa Stykket, bemærkede han, at dette Mineral kendte de godt paa Fabrikken. De Stykker, der modtoges derfra, havde dog et noget andet Udseende, om- endskont dets Forekomst i Kryolithen var overensstemmende med Topasens. Det var blodt, Haardhed ca. 2; det var end- videre graalig gult og blev sort ved Glodning. Ved 100° mistede det 0,3 °/o Vand og ved svag Gladning endvidere 3 °/o. Vegt- fylden var 2,83. Hr. Chr.

Таме VIII viser Vestenden af Kryolithbruddet, saaledes som den saa ud i 1899. Hvad der særlig tiltrækker sig Op- mærksomheden derved, er det morke rektangulære Parti, der findes nederst i Midten af Billedet. Det er en Del af det ejen- dommelige Parti af mørk «sort» Kryolith*) der paa skraat gaar jeg havde medtaget, da jeg syntes, det lignede hverken Kryolith eller Flusspath. I Hintzes Mineralogie staar omtalt en i kemisk Henseende ganske lig- nende Forandring af Topasen fra Stoneham. (Bd. Il, $. 127.) Ogsaa under andre Forhold optræder en sort Kryolith; det er i Vestenden af Bruddet, i det ejendommelige Kvarts-Feldspathparti, der dækker Kryo- lithen mod Vest. Her optræder denne sorte Kryolith som Spalteudfyld- ninger i Feldspathen; ja saa fuldstændig gennemtrænger den denne, at Feldspathen pletvis ganske faar et skriftgranitagtigt Udseende. Her er det aabenbart Feldspathen, der bestemmer «Bogstavernes» Fremkomst, og ved at se dette spørger man uvilkaarlig sig selv: Skulde det samme ikke ogsaa kunne være Tilfældet ved den almindelige Skriftgranit? 10° = — to 144 gennem den hvide Kryolith. Det er som bekendt i denne «sorte» Kryolith, at de ejendommelige store Flusspath Krystaller findes, som Prof. Jul. Thomsen har undersogt og fundet, at de indeholdt Helium"). Disse Flusspathkrystaller gaa 1 Al- mindelighed under Navn af den rede eller redbrune Flusspath, og Navnet er for saa vidt rigtigt nok, som de nesten altid ere rodbrune af udskilt Jernglimmer eller Jærnilte. Det fore- kommer mig imidlertid, at naar den har dette Udseende, maa den vere sterkt forandret, da den er fuld af Sprekker, og disse Sprekker er fulde af smaa Jernglimmerkrystaller. Lykkes det derimod at faa en Krystal frem, der er uden Sprekker og Jern- glimmer, er Farven graa eller brungron. De store Krystaller vise en smuk zonal Struktur, og er Forvitringen skredet sterkt frem, udviskes ogsaa denne tilligemed de smukke brunlige Farve- toner, og Krystallerne bliver graa og faar en straalet Struktur. Om denne Forandring staar i Forbindelse med Afgivelsen af Helium er endnu ikke undersogt. Kryolithen er som bekendt ikke ganske lidt opleselig i Vand; Johnstrup?) angiver at 1 Del deraf oploses ved 12°C. i 2730 Dele Vand, og det er der- for merkeligt, at Bruddet, der ligger ganske ner Kysten, og hvis Bund nu ligger omtrent 130 Fod*) under Havfladen, ег ganske tor, kun noget Overfladevand maa daglig oppumpes. Saa meget merkeligere er det, som Kryolithen er fuld af haarfine Revner, der paa Krys og Tvers gennemskerer den; men da der aldrig er paavist den ringeste Forskydning langs disse Revner, tyder det jo paa, at der siden Massen stivnede, ikke kan vere sket nogen vesentlig Forandring. Det at Brud- det, uagtet Kryolithens Oploselighed og de mange haarfine Revner, stadig vedbliver at vere tort, kan vel kun opfattes som et Bevis for, at Kryolithen ikke direkte berøres af Havvandet, men at det maa vere beskyttet af et Gnejsdekke.

Da dannedes der dybe Klofter langs Revnerne, der nu ere fyldte med Morænemasse: Sand, Ler og store afrundede Sten. En saadan Kloft ses i Midten af Billedet, til Hojre for den midterste af Stigerne; og den Linie, der fra denne Kloft ses i Siksak at fortsette sig hen under Enden af Rebstigen til Hojre, er en tynd Spalte i Kloftens Forlengelse. Spalten er i Virkeligheden lige, det er kun paa den buede Veg at den tegner sig i Siksak. Selv har jeg kun set denne ene morænefyldte Kloft; men den daverende Bestyrer, Hr. Edwards sagde at de havde truffet flere ; de ere ikke vandforende. Jeg skal ikke her komme ind paa Kryolithens Aflejrings- maade; men kun henvise til det nederste Billede paa Tavle XV, der er taget i Bunden af det Hul, der er brudt i Kryolithen paa Grænsen mod Graniten, og som ses overst paa Tavle VIII, og hvor Kryolithen paa denne Grense viser den ejendommelige pladeformede Struktur, der er karakteristisk for, flydende Masser, der ere stivnede ved Afkoling mod Sidestenen, og som saa ofte ses ved plutoniske Gange, men som ikke forekommer hos Masser der ere afsatte af Vandet. Til Slutning maa det vere tilladt at henlede Opmerksom- heden paa nogle farvede Pletter, jeg i 1899 fandt paa den Kry- olith, der ved Ivigtüt stod stablet til Udskibning. Det var smaa rosarede til rødviolette Pletter, der kun fandtes paa Kryolithen paa de Steder, hvor denne var knust ved Slag med Hammeren. Et Sted saas dog en saadan Plet paa Siden af et Borehul. Det er ikke noget Farvestof der er paafort!), det er kun, ligesom at et rodviolet Farvesker udgaar fra Stenen. Da Kryolithen altid er knust paa det Sted, hvorpaa Farven findes, lader der sig ikke slibe et Preparat deraf, og undersoges Pulveret under Mikro- skopet, ses absolut intet. Farven er bestandig i Lyset; thi jeg har haft et Stykke liggende i et Vindue mod Syd i flere Aar, ') De kunne heller ikke forvexles med de rødviolette Pletter, Fuglene af- sætte paa den Tid af Aaret, de særlig leve af Ber. 146 uden at den har forandret sig det mindste; ligesaa er den upaavirkelig af svage Syrer, Vinaand og Æther. Disse farvede Pletter ere lette at finde, naar man forst er bleven opmerksom paa dem; saaledes skrev jeg for nogle Aar siden til Bestyreren af Bruddet og bad ham om at sende mig nogle Kryolithstykker med disse Pletter paa, og pr. Omgaaende fik jeg en hel Del af dem. Ogsaa Professor Ussing bragte fra sin Rejse i 1908 Ргоуег med deraf. Farven minder meget om den rodviolette Farve, flere Mineralier, som Sodalith, Nephelin og ogsaa andre Mineralier fra Sodalithsyeniten i Kangerdluarsuk ses at have, i det Øjeblik de ved Klovning blottes; men som næsten oje- blikkelig forsvinder i Dagslyset. 4. Antikvariske Iagttagelser. Skjendt det aldrig har været min Opgave paa mine Rejser særlig at undersoge de gamle Nordboruiner, saa har jeg dog: altid med den storste Interesse iagttaget dem jeg traf paa. А. Е. Nordenskiöld har fremhevet, at medens man i Norge og Sverige ikke kender en eneste Husruin fra Slutningen af Hedenskabet, saa findes saadanne i Grønland i Hundredevis 1). Burde det end maaske for Grønlands Vedkommende snarere hedde: fra de første Aarhundreder efter Kristendommens Ind- førelse, saa forringer dette ikke Betydningen af det Faktum, at Grønland virkelig er i Besiddelse af en Mængde Ruiner af Huse, der ere opførte i Aarene c. 1000 til c. 1400, og som saa, vist- nok forholdsvis hurtigt ere blevne overladte til sig selv, for derefter, uden synderlig Indgriben fra den efterfølgende Befolk- nings Side, at staa uforandret indtil vore Dage>). 1) Den andra Dicksonska expeditionen till Grönland. $. 367. 2) Selvfølgelig have Eskimoerne, strax efter Nordboernes Uddgen, plyndret Husene for alt, Metal osv., som de kunde bruge, ligesom de naturligvis ogsaa have borttaget Treverket. Spor til at saadant Treverk har veret anvendt i gronlandske Huse eller Grave, vides dog merkelig nok, aldrig at vere paavist. Ligeledes er det merkeligt, at der aldrig er fundet Spor af ædle Metaller, thi disse kunne jo ikke helt forsvinde, selv om Eski- ‘piel TS ee eee 147 Blandt de Grunde, der kunne anføres mod den Opfattelse, at de gamle Nordboere skulde vere gaaet op i Eskimoerne, forekommer disse Ruiners Tilstand mig at vere en af de vesent- ligste; thi allerede da Egede kom til Landet, stod Eskimoerne fuldstændig fremmede over for dem. Aldrig have de direkte benyttet dem; de have kun behandlet dem som andre naturlige Stensamlinger, der kunne benyttes til at indrette Grave eller Ildsteder i. Nordboruinerne kunne passende deles i 3 Grupper; forst Kakortokkirken ved Julianehaab, der ved sin Arkitektur adskiller sig saa fuldstendig fra alle de andre Nordboruiner, at Tanken uvilkaarlig anviser den Plads som opført i den allerseneste Tid, hvori Kolonierne have bestaaet, saaledes som jo ogsaa allerede Graah har antydet det. Den er vistnok langt yngre end den Tid, vi kende fra de gronlandske Sagaer, og stammer vel fra den sidste Tid, hvorom vi kun vide, at der sendtes Bisper til Landet for mulig at redde Religionen og derigennem Befolk- ningen. En saadan Biskop, der var fuldstændig fremmed for Landet og Traditionen i Landet, kan meget vel tænkes at have bygget en ny Kirke paa et saadant Sted, der ligger centralt for hele Osterbygden, men som er uden Forbindelse med de gamle Centrer: Gardar og Brattahlid. Havde Befolkningen selv skullet bygge en ny moderne Kirke, vilde de naturligvis, Traditionen tro, have bygget den paa et af de to sidstnevnte Steder. Kt Udtryk for den Folelse af forholdsvis Nyhed som flere Rejsende have faaet, er ogsaa det, at de have fremsat den Formodning, at Kirken aldrig er bleven færdig. Sans comparaison spiller altsaa denne Kirkeruin samme Rolle som Kirkeböruinen paa Færøerne; men medens det i 1899 lykkedes at faa opklaret naar moerne have benyttet dem; og hvorfor er der i Grenland aldrig fundet hengemte Skatte?, der var dog, under de idelige Fejder og senere under Kampene saavel med Eskimoerne som Seroverne, Grund nok til at hen- gemme Verdigenstande. z 1) Privatboligen paa Island. S. 168. 148 denne Ruin er bygget, saa er Udsigten til at faa opklaret, naar Kakortokruinen blev bygget jo desto verre vel omtrent lig Nul. Efter Valtyr Gudmundsen omtales Vinduer med Glas, — og man kan vel nok forudsette, at der har veret Glasvinduer i Kakortokkirken, — paa Island forst ved Aaret 1195, og ser man hen til Forholdet mellem Island og Gronland den Gang, kan man vel. nok gaa ud fra, at Glasvinduer ere komne betydelig senere til Grønland end til Island. Endnu et Forhold tyder paa, at Kakortokkirken er af sen Oprindelse, og det er det, at det er den eneste Nordboruin, hvorom Eskimoerne have et Sagn om dens Opforelse. Saaledes siger Giesecke'), og det samme siger Vahl”), at Gronlænderne havde et Sagn om, at Stenene til Kakortok- kirken vare tagne paa Ujarartarfik Øerne ud for Lichtenau- Fjord. Uagtet Giesecke til en Slags Bestyrkelse af dette Sagn anfører: «Zum wenigstens sind die dortigen Bausteine, welche ich sah, theils Glimmer — theils Hornblendeschiefer, welche sich am Redekammen nicht so tauglich finden», saa er der dog næppe nogen Tvivl om, at Stenene til Kirken, der forøvrigt slet ikke er bygget af Glimmer eller Hornblendeskifer, ere tagne ved Foden af det nærliggende Kirkefjeld. Derimod turde der maaske ligge noget andet til Grund for Sagnet, nemlig det at de gamle Nordboere mulig kunne have taget Kalksten paa Ujarartarfik Øerne til Mørtel til "Kirken. Mortel findes der nemlig, om end nu meget sparsomt i denne Ruin’), og det er ogsaa den eneste hvori saadant er paavist, og paa Ujarartarfik Øerne findes utvivlsomt en Kalksten; thi dels omtalte den nu afdøde Peter Eberlin, at der fandtes Kalksten dér, og dels 1) Dagbog under 17de Juli 1809. ?) Ms. Dagbog i Botanisk Haves Bibliothek. 3) Ligesom Graah fandt ogsaa jeg nogle Stykker sandblandet Kalk mellem Stenene i Kirkeruinen, og ligesom hans Stykker gik tabt, før de bleve undersøgte, gik ogsaa mine Stykker tabt ved Christiansborgs Brand. 149 fik jeg i 1876 i Julianehaab flere Stykker Kalksten der angaves at hidrøre derfra. — Angaaende Kirkeruinens Arkitektur har Hr. Dr. phil. M. Mackeprang velvilligst meddelt folgende: «Af selve Kirkeruinen!) er det vanskeligt at drage nogen Slutning om dens Opforelsestid, da Formerne ere saa yderlig simple. Hvad Grundplanen angaar, er det den fra Island laante Form, hvor Skib og Kor danner et eneste ligehojt Rum. Den optreder meget tidlig i Moderlandet Norge, men holder sig til Gengeld lenge, helt ind i Gothiken. Det store fladbuede Vindue paa Ostveggen kunde i og for sig tyde paa en sen Tid, men der maa dog gores opmerksom paa, at i norsk Arkitektur træffes Fladbuen baade i 12te og 13de Aarhundrede; og de andre Aabningers Konstruktion med den flade Overligger peger afgjort i denne Retning. Snarest skulde jeg derfor tro, at Kirken var opfort i 12te, maaske 134е Aarhundrede. Jeg maa dog tilfoje, at norsk kirkelig Stenarkitektur fra Middelalderens sidste Aarhundreder endnu er et meget lidt opdyrket Felt.» Nest den enestaaende Kirkeruin ved Kakortok, er det serlig Ruinerne med de cyclopiske Mure, der tiltrekke sig Opmerk- somheden. Dog kan det ikke siges, at Maalet med at sammen- føje disse mægtige Sten, har noget Sted været at tilvejebringe en hel cyclopisk Bygning; thi i Reglen er det kun den ene Side eller den ene Ende af Bygningen der er bygget af saa overordentlig store Sten, at man undres over at de har kunnet magte dem; den anden Side eller Ende af Huset er da i Reglen opført af somme Tider endog ret smaa Sten, saa disse Partier nu som oftest ere nedfaldne. Exempler herpaa ere den be- kendte store Ruin ved Stranden ved Igaliko, der i sin Tid gik under Navnet Brattahliö, og Ruinen paa Øen ud fra Igaliko. Nederste Billede paa Tavle XVI viser denne sidstnævnte Ruin, hvor det, ved Sammenligning med Figuren ses, hvilke store 1) Angaaende Afbildninger af denne, da kan henvises til Tavlerne III—V i Graahs Rejse til Gronlands Ostkyst; PI.

VI. 150 Sten der her i denne, Ostenden: er anvendt; medens de to Rum i Ruinens Vestende, ere opforte af mindre Sten, hvorfor store Partier af denne forlengst ere faldne sammen. Man faar Indtrykket af, at de gamle Nordboere have be- nyttet de Sten, der fandtes paa det Sted, hvor de onskede at bygge, og at de saa forst have stillet de storste Sten sammen, eller endog bygget op ad den storste af dem, som om det var en fast Klippe, og saa siden opfort Murene af mindre og mindre Sten, eftersom de storre slap op, eller det blev for langt at hente flere. Jo mindre Stenene bleve, jo mere synes Gres- torvene at have været anvendte. Derved at der er benyttet en stor Sten som fast Udgangspunkt, kan der ofte fremkomme ejendommelige nisheformede Fordybninger i Murene, uden at saadanne have veret tilsigtede. Saaledes f. Ex. den Nishe, der 1 М. о. G. ViggTavle XII er vist i Fig. Va. At der er tyet til Stensamlingerne for at have Materialet til Husbygningen ved Haanden er naturligt, hvorfor Ruinerne hyppigt findes i Ner- heden af de fra Klipperne nedskredne eller de af Elvene sam- menskyllede Sten. Men selv om Gletscherelvene senere kan have forstyrret en eller anden Ruin, saa gaar Giesecke dog for vidt, naar han tilskriver saadanne Forstyrrelser, helt eller delvis, de gamle Kolonisters Tilintetgorelse !). At der ogsaa kan være bygget huslignende Bygninger af 1) Giesecke: Transactions of the Royal Irish Academy Vol. XIV. 1825. Antiquities. S. 50: All the ruins of Norwegian houses, and there were more than fifty which I examined, were surrounded by immense masses of rocks, probably precipitated from the summits of the adjacent moun- tains, and heaped together in the most fantastic groups, the places of fracture being sometimes so fresh, that the points from which they are broken are distinctly observable. Places of desolation of this kind are frequently met with in the mountains, connected with the sea by water- falls, which are precipitated, with tremendous noise and destructive velocity headlong from the rocks, covered with glaciers. I have no doubt but that such a revolution, caused by bursting glaciers and fol- lowing innundations, has affected this dreadful chaos; and that perhaps the Norwegian settlers perished, and were buried with their cattle in the ruins», 151 ikke anden Grund end den, at et udmærket Materiale fandtes paa Stedet, i Forbindelse med, at Stedet ved sin Beliggenhed at «Ud- kigsruinen» ved Umiausat i Tunugdliarfik er et Exempel paa’). indbed til at bygge et «Lysthus», forekommer det mig, Det er en c. 30 Meter bred Porphyrgang, der her gaar gennem Graniten, og hvis blottede Partier ere sprengte i rektangulere Stykker, der ligefrem indbyde til at «bygge Hus» af. Uden som et Slags Lysthus for de nerboende Folk, kan denne Buin nemlig neppe have haft nogen som helst Betydning, hverken som Pak- hus eller «Fæstning». Udsigten herfra er fortrinlig, baade ud og ind ad Fjorden. Naar der tidligere er brugt Udtrykket «Udkigs- bus» om lignende fritliggende og раа fremspringende Punkter liggende Ruiner, som ved Kagsiarsuk i Igaliko-Fjord og paa Toppen af Kistefjeldet ved Igaliko*), da troer jeg ikke herved Бог tænkes paa noget som helst krigerisk; men kun paa, at det er naturligt, at der bygges skermende Mure mod Vinden paa Steder, hvorfra der haves god Udsigt. Hvad endelig Bygningsmaaden angaar, da er det interessant at se, hvorledes den oftomtalte Ruin paa Skeret ved Igaliko er opført. De to nederste Billeder paa Tavle X vise denne Ruin, dels som den ligger paa dette Sker, der ved Hojvande er nesten helt overfyldt, saa det ser ud som om den flød paa Vandet”), og dels Sydmuren af selve Ruinen. Den østlige Halvdel er nemlig opbygget af skarpkantede Sandstenblokke, der ere brudte paa selve Skeret, der bestaar af Sandsten; medens den vestlige Halvdel er opført af lose afrundede Blokke mest af Grund- fjeldet*). Da det er utænkeligt, at der er slæbt store Rullesten 1) M. 0. G. VI. Таме УП og Compte Rendu du Congrès internat. des Amé- ricanistes. 5te Session. Copenhague 1883. $. 110. 2M 076.

Tangranden strakte sig ind under Ruinens nederste Sten; men ikke én Tangplante kunde jeg finde paa disse. 1) En Del af,den vestlige Halvdel af Ruinen ses til venstre paa Billedet. 152 ud paa dette Skær, for at bygge Hus af dem, kan man vel kun tænke sig, at Skæret oprindelig var belagt med en Morænerest af store Sten. Disse ere saa alle, paa en eneste nær, der ses paa Billedet, benyttede til Opforelsen af Husets Vestende. Enten kan man nu tænke sig, at Ruinen oprindelig ikke har været storre end den Halvdel der er opfort af de lose afrundede Sten, og at den saa senere er bleven udvidet, ved at der skaffedes Materiale fra et Brud i Sandstenen; eller, man kan maaske ogsaa tænke sig, at Bygningen er opfort samtidig af to Partier, et der benyttede de lose Sten, der fandtes paa Skæret, og et der forst maatte bryde Stenene. Da det vel er utænkeligt, at der senere kan være fort Sten bort fra Skæret, kan man altsaa ogsaa være sikker paa, at Huset ikke kan have været hojere end Ruinen nu er!) Hvad Meningen kan have været med at bygge et Hus paa dette Skær”), skal jeg ikke udtale mig om, men henpege paa, at et lignende Forhold findes paa et andet Sted, men rigtignok under noget andre Forhold. Det er den Ruin der ses paa det overste Fotografi paa Tavle X og som findes i en lille So, noget til Fjelds ved Ivsormiut i Tunugdliarfik?). Paa Grund af at Terrainet om Søen er saa fladt, falder Øen paa Fotografiet tildels sammen med Landet. Om denne Ruin, der kun er tilgengelig ved Svomning, hvis man da ikke vil lade 1) Arktander fandt 1751 (Samleren VI. S. 1216) at Hojden var «3 Alen, en- del Steder lidt derover»; og jeg har maalt, paa det Hojeste, 6 Fod 9 Tommer. I 1899 saa jeg ved Hjælp af mine Fotografier fra 1876, at Ruinens Nordside, der er opfort af mindre Rullesten, var bleven noget forstyrret i de mellemliggende 23 Aar. Ogsaa ved den ovenfor omtalte Ruin, der findes paa Øen ved Siden af, er Forholdet det, at Højvandet gaar til Ruinen. Tangranden ligger 2,5 Meter under den Helle hvorpaa Ruinens sydlige Hjørne hviler. End- videre kan bemærkes, at paa den store Sten (ikke Sandsten) der ligger Vest for Øen, naar Tang og Balanranden op til c. 6dm fra Toppen. Naar Dr. C. Pingel (2det skandinaviske Naturforskermøde 1840. S. 354) anfører et Sagn om, at Skæret skal have været større og været land- fast, da vise Dybdeforholdene, at der ikke kan have ligget noget positivt til Grund derfor. 3) Se Kapt. Bruun i M. o. G. XVI. S. 278. be — 153 Kajakker bære derop, beretter Cand. Theilgaard, at Vandet om Øen er dybt; Ruinen er 10 Skridt lang og 6 Skridt bred, udvendig maalt. Der er en Doraabning paa den sondre Lang- side, nærmest den østre Ende. Ruinen staar tvers over Øen, og begge Ender af den beskylles af Vandet. Ostenden er for- trinlig bygget af godt tilpassede firkantede Granitkvadre. Vest- enden er derimod sterkt sammenfalden. Hvorfor der her, saa højt til Fjelds, ег opført en saa solid Bygning i en lille So, er mærkeligt; thi vel er den vel nok over Halvdelen af Aaret til- gengelig paa Isen, men en stor Del af Aaret maatte der Baad til for at komme ud til den, hvis man da ikke, som Cand. Theilgaard, vilde svomme derud. At der i Tidens Leb skulde have dannet sig en So om Ruinen, som ikke havde veret der, da den opfortes, er der Intet der tyder paa. Oprindelig har vel alle disse Bygninger været opførte med Grestory mellem Stenene, ligesom der ogsaa kan paavises Mure, der helt ere opførte af Grestorv, hvilende paa et Underlag af Sten. En saadan ses nederst paa Tavle XVII. Det er Muren i den Ruin Kaptain D. Bruun udgravede i 1894, og som han har afbildet S. 219 i M. о. G. XVI. I de 5 Aar der vare for- lobne mellem Bruuns Udgravninger og mit Besøg i 1899, er denne Græstorvmurs indre Struktur kommen frem, og Siksak- linierne paa Fotografiet vise tydeligt, at Gr&storvene 1 sin Tid bleve sammenstillede paa lignende Maade paa Gronland, som de endnu opstilles paa Island). Hvor Forholdene have været anderledes, har Murkonstruk- tionen ogsaa været en anden. Saaledes paa den c. 26 m. høje Havstok N. for Kordlortok i Nordenden af Tunugdliarfik. Her har Materialet kun været mindre Sten og Grus, hvorfor Siderne af Murene have været opførte af de største af Stenene, medens den Indre har været udfyldt af Grus, saavidt man da kan dømme 1) Se D. Bruun: Gammel Bygningsskik paa de islandske Gaarde. Aars- beretning for Foreningen til norske Fortidsmindesmærkers Bevaring. 1907. S. 8. 154 efter de ringe Grundvolde der findes. Der er ogsaa det ejen- dommelige ved flere af disse Ruiner, at de ikke ligge parallel med Havstokkens Retning, men lodret derpaa, saa den ene Ende af Huset synes at have maattet ligge betydeligt lavere end den anden. Paa denne Havstok findes ogsaa nogle ejendommelige ellip- tiske Stenlegninger; se overste Billede paa Tavle XVI, der bringer Tanken hen paa, at de mulig kunne vere Begravelser. Den her afbildede er dannet af skarptkantede Sten og meget uregelmessig, hvorimod jeg paa en anden Havstok ved Hvæsse- stensfjeld, har fundet dem fuldstændig regelmæssig dannet, som langstrakte Ellipser. De vare dannede af større Sten end dem, der var almindelige paa Havstokken, saa de traadte skarpt frem. Stenene i 3 af dem bleve fjernede, og der blev søgt indtil 14/2 m. ned i de underliggende Strandsten, men intet fandtes"). 1) I 1879 stødte jeg ved Cap Cranstown paa Svartenhuk-Halvø i Nord- Grønland paa lignende elliptiske Stensætninger, M. о.

Ÿ ‘ { 4 \ z ER VE Beretning om Undersøgelserne af Jakobshavns-Isfjord og dens Omgivelser fra Foraaret 1903 til Efteraaret 1904. Af M. С. Engell. 1909. XXXIV. 11 Hensigten med Ekspeditionen var i Hovedsagen at fort- sætte de Undersogelser, jeg havde paabegyndt i Sommeren 1902, og om hvilke der er berettet her i Meddelelserne samt for et enkelt Punkts Vedkommende tillige i Geographische Mitteilungen 1903. Det var oprindelig bestemt, at jeg skulde rejse med Bark- skibet «Geres». Men da dette allerede skulde afgaa fra Koben- havn den 9de Maj, opnaaede jeg ved Hr. Direkter Rybergs Velvilje at faa Tilladelse til at rejse med Direktoratets Damp- skib «Godthaab». Afrejsen fandt først Sted den 5te Juni fra Gronlandske Handels Plads. Uagtet jeg altsaa kom til at rejse en Maaned senere fra Danmark, viste det sig, at jeg dog naaede Egedesminde Dagen, for «Geres» passerede dette Sted. Efter en i alle Henseender behagelig Rejse kom vi paa Hojde med Kap Farvel den 184е Juni. Her laa Storisen et langt Stykke til Sos, c. 18 Somil (33—34 km). Julianehaab- Bugt helt op til Nunarssuit var ligeledes fyldt med Is, saa langt man kunde se fra Udkigstenden. Kaptajn Bang for- sogte desuagtet at komme gennem Isen for at kunne folge Løbene langs Land. Forsøget maatte dog opgives, efter et Etmaals Forløb, hovedsagelig paa Grund af Taage. For mig, der aldrig tidligere havde set Storisen paa nærmere Hold, var denne Tur gennem Isen meget interessant. For det meste var de enkelte Stykker flade, med en ringe Højde over Havfladen (‘/2 Meter eller mindre); Arealet varierede meget, men gennem- gaaende var der ingen Stykker over 100 m. Nu og da saa man en sort Plet paa Isflagerne ; Pletten viste sig at være Sæl- LIE 158 hunde, der styrtede sig i Vandet, naar Skibet nærmede sig. Forevrigt er den store Hastighed, hvormed en Isflage kan skyde sig ud i de aabne Partier mellem Isen og saaledes sperre Vejen for Skibet, forbloffende. Den viser, at der maa vere sterke Stromninger i Vandet, hvorved der skabes Pres. Med Undtagelse af Sæler bemærkedes ellers intet Dyreliv i Storisen. Det forste Sted, vi betraadte i Gronland, var Kolonien Godt- haab, hvortil vi kom den 21de Juni, altsaa efter en Rejse paa kun 16 Dage. Da Direktoren skulde inspicere Kolonien blev Skibet liggende et Par Dage. For at udnytte Tiden foretog jeg Dagen efter en Ekskursion til Lille Malene, en Gnejsknold, der ligger tæt ved Godthaab, for at se lidt paa Vegetationen. Vinteren havde i hele Grønland været meget stræng. Sent paa Foraaret var der tillige faldet meget Sne. Overalt omkring Godthaab og endog paa de smaa lave Øer udenfor laa der endnu store Snedriver i Kløfter og paa Afsatser, og Nordskraa- ningerne var næsten helt sneklædte. Paa Sydskraaningerne var Sneen derimod ved at smelte bort, og Smeltevandet sivede overalt nedover og gennem Vegetationsdækket. Som Følge af disse Forhold var Plantevæksten endnu meget langt tilbage. Kun faa Arter og Eksemplarer havde naaet at udvikle og udfolde Knopper og Blomster og det endda kun paa de gunstigste Lo- kaliteter — nemlig enkelte Sydskraaninger. Den Plante, der var længst fremme, var selvfølgelig Empetrum nigrum; den var nu næsten helt afblomstret; kun ganske enkelte Eksem- plarer stod endnu med støvfyldte Knapper. Vaccinium uligi- nosum og Salix groenlandica stod med modne Støvknapper, ligeledes Salix herbacea. Paderokken, Æquisetum vulgare, havde modne Sporer. Loisleuria procumbens og Diapensia lapponica stod med Blomsterknopper færdige til at springe ud. Betula nana stod i Knop; kun faa havde udfoldet Knopperne og stod med modne Rakler. Salix glauca stod derimod næsten allevegne kun i Knop. Ledum palustre og Phyllodoce coerulea 159 var ikke engang udstyrede med synlige Blomsterstande. Sammen- ligner jeg dette med mine lagttagelser fra Jakobshavn den 22de Juni 1902, var der en meget betydelig Forskel i Plante- vekstens Udvikling — i Godthaabs Disfavor — uagtet Jakobs- havn ligger paa с. 69° п. Вг., medens Godthaab ligger раа 63° n. Br. Ved Jakobshavn var paa samme Tid i 1902 alle de ovenfor nævnte Planter meget lengere fremme. Den 23de om Eftermiddagen lettede «Godthaab» og satte Kursen mod den neste Koloni nord for Godthaab, Sukker- toppen, hvortil vi ankom Dagen efter, den 24de, tidlig om Morgenen. I Sukkertoppens umiddelbare Omegn var der nesten ingen Sne, og Vegetationen var lengere fremme end det 1° sydligere liggende Godthaab. Dette beror hovedsagelig paa, at Sukkertoppen ligger serdeles lunt, beskyttet mod kolde Vinde af hoje Fjelde; men Havstromningerne udenfor spiller sikkert ogsaa en Rolle. Om Aftenen samme Dag, som vi var kommet, afgik Skibet til de neste Kolonier: Holstensborg og Egedesminde; et vedholdende Regnvejr forhindrede i Holstensborg en ner- mere Besigtigelse af Vegetationen. Sne var her meget mindre af end i Godthaab. Efter at vi den 27de om Eftermiddagen var kommet til Egedesminde gik jeg fra Borde. «Godthaab» skulde nemlig videre nord paa til Upernivik for at hente Be- setningen fra et af Isen ituskruet Hvalfangerskib — forevrigt det fra Nordenskiölds Færd saa berømte «Vega». — Forst paa Tilbagevejen vilde «Godthaab» anlobe Jakobshavn. Da jeg altsaa blev sat af her i Egedesminde — ganske vist uformodet — besluttede jeg mig nu, da der maaske var Lejlighed til at komme ind i Aulatsivik-Fjord. De шаге Dele af denne Fjord er kun delvis kortlagt; Jensen og Korneru р har passeret dens sydlige Gren. I den nord- lige har Nordenskiöld været med «Sophie». Det var særlig til denne Del af Fjorden, jeg gerne vilde frem. Dels havde det sin Interesse at se, om Gletscheren havde forandret sin Beliggenhed 160 siden Nordenskiölds Tid, dels vilde jeg forsage at kort- legge Grensen mellem Indlandsisen og Landet, hvorved jeg fik Forbindelse mellem det i 1902 undersogte Orpigssôk. Ende- lig vilde jeg forsoge at faa afgjort om det flade Land mellem Aulatsivik-Fjord og Disko-Bugt havde en lignende Oprin- delse som det flade Land syd for Klavshavn. I Anledning af Direktørens Ankomst kom der adskillige Konebaade til Kolonien fra Bopladserne i Omegnen: for saa vidt var det ikke vanskeligt at faa fat i en Konebaad. En af de Gronlendere, der var kommet til Kolonien med Konebaad og som hørte hjemme i Kangarssuatsiak, Boplads mellem Egedesminde og Aulatsivik-Fjord, sagde han kendte Fjor- den rigtig godt og tilbod at vere Styrer. Som vi senere skal se var enten hans Kendskab ikke stor eller ogsaa havde han — diplomatisk — ikke udtalt sig nærmere om Fjorden; den var nemlig, som jeg senere erfarede, paa denne Tid altid stu- vende fuld af Is. Den 29de rejste vi syd paa gennem Egedesminde Sker- gaard og overnattede paa en mindre 9, Inugsutusut. Vejret var ægte Strædevejr, raakoldt og taaget, meget forskelligt fra det Vejr, jeg var vant til ved Jakobshavns-Isfjord. Sne var der her iEgedesminde-Distriktet kun lidt tilbage af, hovedsagelig kun paa Nordskraaninger og i Kløfter, hvor der var føget sær- ligt meget sammen. Vegetationen var ogsaa her betydeligt længere fremme end ved Godthaab; det maa dog samtidig erindres, at Tiden var rykket en Uge frem. Salix glauca stod med helt udfoldede Knopper og med modne Rakler, Betula nana ligeledes. Silene acaulis blomstrede. Fra Inugsutusut sejlede vi videre syd paa til Aulat- sivik-Fjord, men allerede et Stykke indenfor Mundingen, var den endnu saa fuldpakket af Kalvis og Vinteris, at Kone- baadsstyreren havde Ret i, at det vilde være umuligt nu at komme frem. For yderligere at overbevise os om det triste i Situationen spildte vi — Konebaadsstyreren og jeg — næsten 161 en hel Dag med at komme op paa nogle hoje Bjergtoppe, fra hvilke vi havde en god Udsigt over den ydre Del af Fjorden: desverre Is overalt i Fjorden i saadan Mengde, at en Kone- baad ikke vilde kunde klare sig. Forovrigt plejede Fjorden ikke at vere nogenlunde isfri for i den sidste Del af Juli, bedst er den at befare i August og til Dels i September — saaledes fortalte man mig i Niakornak, en Boplads i Fjordens Mun- ding. I den Henseende forholder altsaa Aulatsivik-Fjord sig som andre Fjorde, i hvilke der gaar Isstramme ned f. Eks. Torsukatak-Fjord. Under disse Forhold maatte jeg atter vende tilbage til Egedesminde, hvorfra jeg sejlede videre med Konebaad til Klavshavn, hvortil jeg kom den 6te Juli. Jeg søgte at bevæge Konebaadsforeren til at legge Vejen over Kitsigsunguit, af Danskerne kaldet «de grønne Øer» efter den i Gronland usedvanlig tette Gresvekst, fremkaldt af den utallige Mengde Terner, der ruger der; men Konebaadsforeren frygtede det brede Farvand, vi skulde over og foreslog, at vi hellere maatte tage over den lille @ Upernivik 9: Foraars- stedet, fordi Gronlenderne i Forsommeren pleje at staa i Telt her paa Fangst. Uagtet der ingen Gronlændere stod i Telt, da jeg var paa Øen, var det let at se, at Øen var en yndet Teltplads: Alopecurus alpinus, der er Bopladsernes ufra- vigelige Ledsager, dannede et tæt og meget smukt Gronsver ; de mange Gronlændergrave beviste. ogsaa, at Men var et søgt Fangststed. I Klavshavn var ved vor Ankomst Atak-Fangsten i fuld Gang. Det kneb derfor meget med at skaffe Besætning og Baad til den paatenkte Tur ind i Tasiussak. I Fangsttiden, hvor der er rigeligt med Mad, holde de unge Knose, der alligevel intet fanger, mere af at gaa og drive end at bestille noget, et Forhold de eldre Gronlendere ikke er blinde for. Omsider fik jeg dog samlet en Besætning sammen, og med denne tog jeg saa ind til Tasiussak; men den for Forbin- delsen vigtige Autdlarisap-Tasia var endnu islagt. Des- 162 verre var Isen for mor til, at man kunde gaa paa den. Naar man satte Foden haardt i, oplostes Isen i henved decimeter- lange Stengler. Denne stænglede Struktur af Is kan man som bekendt ogsaa iagttage herhjemme. Konebaaden maatte altsaa bæres helt syd om Seen og uden om Kiagusuk-Fjeld. Denne Ombering er lang og besverlig og tager megen Tid. Medens Mandskabet bar Baaden over, saa jeg lidt paa Vegetationen. Det var iøjnefaldende, at Foraaret ogsaa her var kommet meget sent. Sneen var ganske vist helt forsvunden, naar undtages visse Steder, hvor der var foget Driver sammen. En Plante Pyrola grandiflora, der 1902 stod i Blomst den 22de Juni, var endnu ikke udsprunget den 74е Juli; selv Dryas integri- folia var forst sprungen ud for nylig; kun faa Eksemplarer stod i Blomstring. Ellers var de andre Hedeplanter nu i fuld Blomstring: Rhododendron lapponicum, Silene acaulis о. a.; Vaccinium uliginosum var endog nesten afblomstret. Forst Dagen efter var Konebaad og Bagage naaet helt ned til Tasiussak. Denne var paa dette Tidspunkt ganske fri for Vinteris; Isfod var der intet at se af. Nu gik Roturen ind gennem Tasiussak til Kekertarsunguit-Tupersua — naturligvis med de nodvendige Ophold —. Her slog jeg Telt og begav mig om Eftermiddagen paa en Fodtur til Teltplads- knuden, idet jeg og mine Ledsagere gik over et Pas i Kekar- tarsunguit-Kulà. Uagtet det var temmelig sent om Efter- middagen vi begav os af Sted, var Myggene meget ubehagelige; for hvert Skridt man tog, for der en Sverm op af Lyngen. Overhovedet var Myggene denne Sommer næsten uudholdelige; Aarsagen til den store Myggerigdom, som jeg slet ikke be- mærkede i 1902, maa vist søges i det sene Foraar og rigelige Nedslag om Vinteren; alle Huller var i Aar fulde af Vand. Om Natten — for saa vidt man kan tale om Nat i den lyse Tid, er Myggene temmelig fredelige, hvorfor man staar sig ved at arbejde om Natten og sove om Dagen; ganske vist har Myg- 163 gene en fænomenal Evne i Retning af at finde et Hul, hvori- gennem de kan komme ind i Teltet. Fra Teltpladsknuden har man en udmerket Udsigt over Jakobshavns-Isfjord og Enden af Jakobshavns-Gletscher. Selve Isfjorden frembod det sædvanlige Skue: aldeles tætpakket af større og mindre Kalvisstykker, mange af sædvanlige Isfjeldes Dimensioner; alt er hvidt. Et eneste Isfjeld af samme Type som de i min Beretning af 1902 omtalte fandtes. Det stod med lodrette Sider og en takket ujævn Overflade af en mere graalig Tone — hidrorende fra Støv, der fra Land er blest ud paa Gletscheren, medens Isfjeldet var en Bestanddel af denne. Da det har stor Interesse at faa Hojden af saadanne Isfjelde i oprindelig Stilling sammenlignet med Hojderne af Gletscheren, foretog jeg — foruden Nivellement med Haandniveau — et trigonometrisk Nivellement, idet jeg udmaalte en Basis og fra Endepunkterne foretog de nødvendige Vinkelmaalinger. Re- sultatet gav, at Isfjeldet var 9 m lavere end det Parti af Isstrommen paa det Sted, hvor Isfjeldet paa det nærmeste maatte antages at have losnet sig. Denne Forskel betyder dog ikke noget absolut, idet Fikspunktet paa saavel Isfjeldet som Isstrommen maa tages nogenlunde tilfældigt som en markeret Spids og udsiger altsaa intet nojagtigt om den gen- nemsnitlige Hojde af saavel Isfjeld som Gletscher; men som vi senere skal komme tilbage til, kan der ikke vere Tvivl om, at disse Isfjelde i oprindelig Stilling losner sig fra Gletscheren ved en Revne, og da ligge de nojagtigt i samme Niveau som Gletscheren. Der kan altsaa ikke vere Tvivl om, at den yder- ste Ende af Gletscheren flyder paa Vand efter de hydrostatiske Love. Kalvningen af disse Isfjelde i oprindelig Stilling kan altsaa ikke foregaa hverken ved Nedstyrtning eller Opdrift; men maa foregaa derved, at der, under Isens uensartede Bevægelse fra Randen af Fjorden og ud mod Midten, opstaar Spændings- forskelle, der resulterer i Brud, og da de foran Isstrommen liggende Ismasser ikke formaar at udove et tilstrækkeligt Tryk 164 mod det frasprængte Isstykke, vil dette ikke ved Regelation atter fryse sammen med Gletscheren. Overhovedet spiller maaske en Isfjords Pakning af Kalvis en betydelig Rolle med Hensyn til den Maade paa hvilken Isstrømmen kalver. I den Henseende er netop Jakobshavns-Isfjord ualmindeligt stærkt pakket, idet der ved Mundingen af den ligger den be- kendte Isfjeldsbanke, der næsten ganske stopper for Kalvisens Udførelse af Fjorden. Hvis der nemlig ikke er noget Modtryk af Kalvismassen mod Isstrømmens forreste Rand, kan man vanskelig tænke sig, at Isstrømmen skulde kunne skyde sig saa langt ud, at den kan flyde paa Fjorden; paa Grund af de oven- for omtalte Spændinger maatte Enden af Isstrommen snart springe itu, og da der intet er, der presser imod, vilde Regela- tionen udeblive: Enden af Isstrømmen altsaa henfalde til mindre Stykker, netop den Slags man ser i mindre tætpakkede Isfjorde f. Ex. Torsukatak. Saa vidt jeg ved, har ingen tidligere be- mærket disse Isfjelde i oprindelig Stilling i Nord-Grønland, og efter al Rimelighed forekommer de her kun i Jakobs- havns-Isfjord, som den mest ispakkede Fjord. Noget nævneværdigt Udbytte af at studere Kalvningsfænomenerne i Jakobshavns-Isfjord som Forbillede for Kalvningerne i andre Fjorde har man altsaa ikke, fordi Forholdene der er saa afvigende fra andre Isfjorde. ) Til en skarp Bestemmelse af Gletscherrandens Beliggenhed egner Teltpladsknuden sig ikke mere, da Gletscherranden nu har trukket sig længere mod Øst, hvorved man i altfor høj en Grad kommer til at se Randen en face. Jeg tog dog et Foto- grafi af Situationen, og fra Endepunkterne af en Basis tog jeg med Teodolit Sigter til et Punkt i Gletscherranden omtrent midtvejs mellem Midten af Gletscherranden og Fjordens Side. En Udregning gav, at delte Punkt skulde ligge c. 350 m læn- gere fremme end Gletscherranden gjorde det foregaaende Aar. Det maa dog bemærkes, at den benyttede Trekant havde en meget lille Basis i Forhold til Sidernes Længde, tilmed var den 165 meget skævvinklet. Forevrigt maa man erindre, at 350 m ikke beiyder saa meget her, hvor alle Dimensioner er saa store, og hvor Isens Hastighed er saa stor; blot der losner sig et Par storre Isbjerge er tilstrækkeligt til, at Gletscherranden paa det nermeste kommer til at ligge, hvor den laa det foregaaende Aar. Randpartiet af Gletscheren havde nedenfor Teltpladsknuden losnet sig; 1902 havde den her dannet ligesom en Bremme. Dette kan sikkert tydes som en Tilbagegang af Gletscheren, idet vi nemlig maa erindre, at Randpartierne af Gletscheren bevege sig paa selve Bunden af Fjorden og saaledes ikke er underkastet de samme Svinger som Midterpartierne af Gletscheren, der flyder paa Vandet. For at faa en nojagtigere Bestemmelse af Beliggenheden af Gletscherenden forsøgte jeg at komme over til Nunataken. Den Ely, der løber mellem de to Seer var stærkt opsvulmet, saaledes at det var umuligt at vade over. Af det Ler og Slam, som var afsat paa Stenene, kunde man se, at den for nylig havde staaet endnu højere; i Løbet af en fjorten Dages Tid vilde den være sunket saa meget, at man kunde komme over. Selve Søerne var endnu delvis islagte, men Isen var fuldstændig mør. Da jeg.altsaa alligevel ikke kunde naa over til Nunataken, vendte jeg tilbage til Teltpladsen, Kekertarssunguit-Tuper- sua. Herfra sejlede jeg med Konebaaden til Alangordlek- Gletscher, for nærmere at undersøge om denne Gletscher muligen ogsaa trak sig tilbage og for muligen at blive klar over dens Maade at kalve påa. Nogen Forandring i Beliggenheden af Gletscherens Ende kunde jeg ganske vist ikke paapege. Men at Gletscheren er enten stationær eller snarere i Tilbagegang, synes mig at fremgaa deraf, at der langs Gletscheren findes en frisk, aldeles ube- vokset Morænevold, en Endemoræne. Højden af Gletscherenden over Havet overstiger næppe noget Sted 25 m. Hastigheden er ringe, da der næsten ingen Kalvis dannes. Overalt luder Gletscherenden frem over. Nogen Kalvning fandt ikke Sted; 166 heller ikke horte jeg under mit Ophold den kanonadeagtige Stoj, der altid folger med Kalvningerne. De ganske smaa og spredte Stykker Kalvis dannes vistnok simpelthen af Nedstyrt- ninger. Besætningen vilde nu tilbage til Klavshavn, hvilket jeg maatte give Lov til; paa Tilbagevejen slog jeg atter Telt ved Kekartarssunguit-Tupersua, hvorpaa jeg foretog en ny Ekskursion til Teltpladsknuden; men nye Resultater frem- kom ikke. Gletscherenden havde ikke forandret sig kendeligt i den Uges Tid, jeg havde veret ved Alangordlek; kun var der flere Steder styrtet betydelige Partier af Gletscherenden ned. Det ovenfor omtalte Isfjeld var rykket lidt længere ud i Fjor- den. Nunatap-Tasia var endnu delvis islagt. Da Gronlenderne stadig klagede over, at deres Kamiker var saa daarlige — et almindeligt brugt Paaskud, naar Gron- lenderne ikke vil vere ude mere — maatte jeg opfylde deres Onske om at komme tilbage til Kiavshavn. Som allerede berort i min Beretning om Rejsen 1902 er Klavshavns Befolkning ikke behagelig at have med paa en lengere Tur. Det er en noget lad Befolkning. Man ser altid i Klavshavn kraftige unge Mennesker, som slet intet bestiller ` ud over at ryge Tobak og glane ud over Havet. Der er ved Klavshavn en god Fangst og efter gronlandsk Skik og Brug falder der altid lidt af til dem, der intet har fanget; det er derfor ikke nodvendigt at slide for Foden. Naboskabet til de to Kolonier Jakobshavn og Kristianshaab har vel heller ikke gavnet. Meget behageligere at have med at gore er Gronlænderne i Torsukatak og i Sydost-Bugt. Da meget afhenger af den Besætning, man har med sig, foretrak jeg at gaa videre mod Nord for der at skaffe en flink Besætning. Desuden skulde jeg alligevel helst ind i Torsu- katak-Fjord, for at undersoge om Gletscherne der var 1 Tilbage- eller i Fremgang. 167 Fra Klavshavn gik altsaa Rejsen over Jakobshavn, hvor jeg hentede Proviant, til Rodebay, en mindre Boplads, hvis Navn stammer fra den hollandske Hvalfangsttid. Hvorfor den har faaet Navnet Rodebay 9: rode Bugt er usikkert. Fjel- dene deromkring er ikke rodere end andre Steder. Paa gron- landsk hedder den Okaitut (Skarvene); Navnet stammer fra, at der i sin Tid i de stejle Fjelde bag den nuverende Boplads rugede Skarve. Efter hvad en Gronlender meddelte, var disse nu udryddet her. Bopladsen lig- \ ger ved en temmelig fladvandet Bugt med god Ankergrund — formodentlig Aarsagen til, at de hollandske Hvalfangere holdt til her —. Befolkningen er behage- ligere at have med at gore end Klavshavnerne og Jakobshavnerne. Fra Rodebay gik Rejsen videre til Klokkerhuk. Kone- baadene plejer, naar Vejret er godt, at gaa over det tre Mil brede Farvand mellem Kangarssuk og Sarkata, den sydligste lavere Del af Arveprinsens-@ (paa grønlandsk Agdlutok). Vejret var lidt ustadigt denne Gang, og derfor gik Konebaadsstyreren helt op til Niakornak, før han satte over. Da vi kom om- kring Øens Sydspids begyndte det at friske op, saaledes at vi maatte slaa os ned ved Klokkerhuk, hvor vi paa Grund af daarligt Vejr maatte blive to Dage. Selve Klokkerhuk er en lille knoldformet Halvø forbundet med Hovedlandet ved en flad Strækning (Fig. 1). Denne Landtange er dannet ved, at de skiftende nordlige og sydlige Vinde har kastet Grus og Sten op i en Vold. For Øjeblikket bryder Havet ned, hvad det tidligere har opbygget, formodentlig fordi Landet sænker sig. Tidligere var 168 Klokkerhuk en vigtig Boplads, fra hvilken der blev drevet en ret betydelig Hvalfangst; et Minde om dens fordums Betyd- ning har man i de mange Eskimograve i en eldre Strandvold. Nu er Klokkerhuk ganske ubeboet, kun nu og da ligger der en Baad fra Ritenbenk paa Fangst her. For at rejsende om Vinteren kan søge Ly her, findes der opført et Hus, forøvrigt ganske forfaldent og molesteret af Gronlenderne. Til nogen storre Nytte er det neppe; de fleste Slederejser gaar i Reglen ost om Øen, da Disko-Bugt i de senere Aar sjælden lægger til. Omsider bedagede Vejret sig, og vi kunde atter fortsætte Rejsen til Ritenbenk. Allerede naar man kommer uden for Klokkerhuk kan man se det hoje Forbjerg Kangek, lige syd for Ritenbenk. Man tror man er ner ved, og dog er der 3—4 Timers Rotur fra Klokkerhuk til Kangek. Vest- kysten af Arveprinsens-Q, eller som den i ældre Tid kaldtes Arveprinsens-Ejland er meget ensformet uden Pynter, Sker og Bugter. Lagene helder ind ad og har Strygning pa- rallel med Kysten, saaledes at der ikke bliver noget videre at bearbejde. Tilmed findes der kun faa Веупег og Spring. Kangek er netop opstaaet ved et saadant megtigt Spring. Ritenbenk, skal efter hvad Dr. Steenstrup har oplyst, vere dannet ved Omsætning af Bogstaverne i Berkentin og har altsaa ikke noget med Ride, den tretaaede Maage, og bank, Fuglefjeld at gore. Paa gronlandsk hedder Bopladsen Agpat efter et Fuglefjeld tet ved, hvor der ruger et Utal af Tejste af Danskerne kaldet Alke; den egentlige Alk, Klubalken ruger ogsaa paa Fuglefjeldet, men er langt sjeldnere. Alke- fjeldet her ved Ritenbenk er dog efter Beskrivelsen at dømme meget mindre end Alkefjeldet ved Upernivik. Fra Kangek og nordpaa er Arveprinsens-@ meget indskaaret, som Folge af den meget uregelmessige Lejring af Gnejsen; Sejladsen fra Ritenbenk nord paa er derfor meget afvekslende. Efter en lille Dags Rotur naaede vi Kekertak 169 («Øen») en lille ©, der ligger inde i en Sidebugt til Torsu- katak, og hvor der findes en lille Boplads og et «Udligger- sted». Paa de Fremspring, der danner Bugten, ligger to Bo- pladser Nugak og Ekogfat. I den ydre Del af Torsukatak saa vel som her i Kekertak-Bugt, laa der kun lidt Drivis. Sejladsen ind gennem Fjorden gik derfor godt til at begynde med, men i den mellemste Del nord for Kekertakasik (eller som den her med Provinsudtale kaldes Kekertakasak) var der dog saa megen Drivis, at vi maalte gaa syd om denne Ø for at naa ind til Ana («dens — formodentlig [sens — Exkre- ment»), et Navn der ogsaa forekommer i Upernivik-Distrikt paa en lignende Halve, der skyder sig ud fra Indlandsisen. Formodentlig sigtes der ved Navnet til, at Halvoen rager frem fra den hvidlige Indlandsis som en mork Masse. Paa den nordvestlige Spids af Halvoen ligger der en Boplads af samme Navn som Halvøen. For Øjeblikket fandtes der kun to Huse; for et Par Aar tilbage var der 3 Huse, men den ene Familie flyttede til Arsivik, hvorfra der er lettere Forbindelse med Handelspladsen Ata. Ved vor Ankomst var begge Familier draget paa Fangst; kun et Spand Hunde var tilbage. Det var forøvrigt min Hensigt at naa tværs over Fjorden til et For- bjerg, Nuk, tet ved den nordlige Gletscher, hvor Dr. Steen- strup har foretaget Hastighedsmaalinger af Gletscberen samt fotograferet den. Det var imidlertid ganske umuligt at komme igennem. Det er forøvrigt værd at bemærke, at der om Natten selv i den varmeste Maaned danner sig Tyndis inde i Isfjor- dene. For at faa Overblik over Gletscherforholdene besteg jeg et Fjeld tet bag Bopladsen. Fjeldet hed Sagdliarusek, og man har derfra en udmerket Udsigt over Isen og Fjorden. Paa Toppen fandtes en Varde, helt mosgroet og altsaa af gammel Dato; maaske er den stablet af Hammer 1883. Nogen Forandring i Beliggenheden af de to Gletschere kunde jeg ikke paavise ved at sammenligne Gletschernes nuve- rende Stilling med Fotografier tagne af Dr. Steenstrup. Dog 170 maa den langs Siderne liggende Endemoræne, hvis lysegraa Farve stikker saa stærkt af mod de morke, likenbevoksede Klippe- vægge, tydes som et Tegn paa, at Gletscheren i Øjeblikket er i Aftagende. Hele det indre af Torsukatak var fuldstendig opfyldt af Kalvis, op af hvilken der her og der ragede enkelte Isfjelde. Isfjelde i oprindelig Stilling, saaledes som jeg har omtalt det for Jakobshavns-Isfjords Vedkommende, var der intet at se af. Gletscherne skrider ned mod Havet med et meget stærkere Fald end i Jakobshavns-Isfjord. Kalv- ningen er derfor sandsynligvis helt forskellig de to Steder. Medens vi opholdt os paa Fjeldet, maa der have fundet Kalv- ninger Sted, da vi hørte den med Kalvningerne forbundne Støj; men hvorledes Kalvningen foregik, fik vi ikke Lejlighed til at iagttage. Da jeg altsaa paa Grund af Ishindringen i Torsukatak ikke kunde naa over til Nuk, sejlede jeg videre syd paa og vilde have været i Land ved de to sydlige Gletschere Sermia avanarlermata og Sermia kujadlermata; men Kone- baadsstyreren, der var fra Ritenbenk, havde aldrig været i Nærheden af Indlandsisen og turde ikke komme den nær. An- tagelig vidste han, at der ved Kalvningerne opstaar stærk Bølgegang; denne har han saa anset for at være farlig for Kone- baaden, hvilket han ikke behøvede, da det slet ikke var min Agt at komme Gletscherne såa nær med Konebaad. Maaske har han ogsaa næret nogen overtroisk Frygt for Indlandsisen, hvilket ikke er ualmindeligt hos de Gronlændere, der bor fjernt. fra den. У! maatte derfor nøjes med at gaa i Land paa Igdloluarssuit («de store Huse»), en Ø, der ikke er mere end 400 m høj; men hvorfra man har en udmærket Ud- sigt over de to nævnte Gletschere. Syd for den sydligste lig- ger der langs med Landet, Nuna-Kigdlinga, i en Afstand af c. 2 km en (5—6 km) lang Morænevold paa Indlandsisen. Denne Bundmoræne maa opstaa ved, at Isen paa Grund af Terrainets Form skyder sig op efter. Hammer omtaler ikke 171 denne ellers meget iojnefaldende Morenevold og heller ikke Steenstrup. Maaske er det et Fenomen, der forst i den senere Tid er fremkommet, i Lighed med Nunatakerne ved Jakobshavns-Gletscher; hvis det er Tilfeldet, synes More- nens Fremkomst at tyde paa, at Isen nu staar lavere end tidligere. Fra vor Teltplads ved en lille Bugt, Omare, paa Øens Vestside vendte vi tilbage til Kekertak. Farvandet mellem Igdloluarssuit og Kekertakasik ег fuldt af lave Øer, og Farvandet er vistnok ikke ret dybt; i hvert Fald er der en meget sterk Strom her. Det samme syntes mig ogsaa at vere Tilfeldet mellem Ana og Kekertakasik samt i Farvandet mellem denne @ og Arsivik-Land. Da Indlandsisen havde en større Megtighed end nu, har de to Gletschere inden for Igdloluarssuit sikkert skudt sig ud gennem Atä-Sund, fordi Torsukatak-Fjord har veret helt udfyldt af Torsu- katak-Gletscher. Farvandet syd for Kekertakasik har derfor ligget i Le og er ikke blevet eroderet. Men forevrigt er det vanskeligt helt at komme paa det rene med disse For- hold, saa lenge Isfjordene ikke er oploddede. Efter at vere naaet tilbage til Kekertak foretog jeg en Ekskursion til Sarkak-Gletscher. Sarkak-Gletscher skyder ned fra det hoje sneklædte Land, der iigger syd for de store Seer. Dens Fald er meget betydeligt. Foran Gietscherne var der aflejret en betydelig, ganske ubevokset, Morenevold. I Forhold til denne syntes det, som Gletscheren har trukket sig noget tilbage. Snegrensen synes her at ligge ganske paa samme Hojde som paa Plateauet indenfor Kekertak-Bugt. Selve Bopladsen Sarkak, der ligger lidt lengere mod Vest, gor et meget tiltalende Indtryk. Den ligger ved en lille Bugt, hvis Indlob beskyttes af en lille ©. I visse Henseender minder den lidt от et dansk Fiskerleje; det er vel ogsaa den mest velstillede Boplads ved Disko-Bugt. De megtige Is- XXXIV. 12 172 fjelde, der driver ned gennem Vaigat, hidlokker Sælerne og skaffer derved god Fangst. Fra Sarkak vendte jeg tilbage til Ritenbenk, hvor jeg skaffede mig en Besætning, der lovede at folge mig inde i Tasiussak hele Sommeren. Begyndelsen var ganske lovende. Turen fra Ritenbenk til Jakobshavn, 11 Mil, blev tilbage- lagt paa en Dag, hvorpaa jeg drog ind i Sarkardlek-Fjord. De Lodninger, jeg foretog her, gav til Resultat, at denne Arm af Tasiussak ikke er videre dyb, c.90m. Ved at bestemme Hojden af Gletscheren kom jeg til det Resultat, at de midterste Dele af Gletscherenden havde en Højde af 30 m over Hav- spejlet, enkelte Toppe hevede sig til 35 m. Man kan vel an- tage, at den kompakte Ismasse ikke hæver sig over 30 m over Havet. Hvis nu Drygalskis Teori om, at Gletscherne kalver der, hvor de begynder at miste Fodfestet, er rigtig, saa skulde Dybden af Fjorden ved Gletscherenden beløbe sig Ш с. 225 т, idet vi antager, at den Del, der er under Vand, er 71/2 Gange saa stor som den Del, der rager op over Vandet. Lodskuddene viser imidlertid, at saa dybt er der langtfra i Fjorden. Dry- galskis Teori om Kalvningen skulde altsaa herefter ikke vere geldende. Dog bor det ikke lades ude af Betragtning, at der kan tenkes den Mulighed, at Gletscheren ligger saaledes som det ег anskueliggjort paa hosstaaende Tegning (Fig. 2). Meget taler dog mod dette. Navnlig maatte da den Del af Gletscher- enden, der beskyttet af Havets oplosende Virksomhed af den foran aflejrede Moræne, springer stærkt frem under Vandet, paa Grund af Opdriften sprænges fra og skyde op med en betydelig Hastighed. Saadanne opskydende Ismasser har jeg aldrig iagt- taget, og efter Beskrivelserne har heller ikke andre iagttaget saadanne. Naar man har angivet, at Isfjelde har raget op over Gletscheren og atter sunket tilbage, saa behover dette blot at have veret Flager, der efter Losningen fra Gletscherenden under deres Bestrebelse for at finde Ligevegtsstillingen med en Spids har raget op over Gletscherens Overflade. At Isfjelde med en 173 Тор kan rage op over Gletscherens Overflade er forøvrigt alle- rede omtalt i Meddelelser om Granland 26 Bd. Efter at jeg har foretaget nævnte Lodninger, mener jeg altsaa, at man maa forlade Drygalskis Hypotese. Som jeg senere hen kommer tilbage til, tyder Forholdene ved Kiakusuk paa, at en Gletscher kan staa meget lavere med sin Underflade end den foranliggende Havbund. Men der- med vere ingenlunde sagt, at Forholdene er saadan som an- skueliggjort paa Figuren. Sep ppm Er Fig. 2. Under Opholdet ved Sarkardlek var min Opmerksomhed naturligvis i hej Grad henvendt paa Sporgsmaalet om, hvor- ledes Gletscheren kalvede. Man kan ikke undgaa at legge Merke til, at Gletscherenden stadig stiller sig med fremadheldende Flade, og at den Del, der ligger i Vandet, er meget afgnavet; dette ses tydeligst, naar det er Lavvande (se forøvrigt hosstaaende Skema Fig. 3). Naar Heldningen har naaet en vis Størrelse, omkring 10°, og der er gnavet tilstrækkeligt meget bort af Vandet, kommer der et Qje- blik, hvor Sammenhengskraften ikke lenger formaar at gore sig geldende; men der skér en Bristning, og den flade Knold i2* 174 falder ned i Vandet. Dette har jeg flere Gange haft Lejlighed til at iagttage. Naar den Skive, der losnes, ikke gaar i Stykker, hvilket hyppigst sker, falder den om paa Siden. Efter Kalv- ningen staar Gletscherenden for det meste med lodrette Ende- flader, ofte endda heldende en Smule bag over. Vedbliver man at iagttage et saadant Parti, hvor der er sket en Nedstyrtning, legger man Merke til, at Gletscherenden fra at vere tilbageheldende bliver lodret og derefter fremadheldende ; samtidig ser man Vandet oplese mere og mere af Isen i Vand- LON, Win skorpen. Naar saa Heldningen er blevet tilstrækkelig stor, og Vandet har gnavet af Isen, sker der en ny Nedstyrtning, en Kalvning; Tidspunktet afhenger af flere Ting, saaledes Rev- nernes Dybde og Kalvninger i Nærheden. Hvis nemlig Rev- nerne er serlig dybe, og der finder Kalvninger Sted i Nerheden, kan der indtrede en Nedstyrtning, for der egentlig skulde. Nogen Opskydning af Isfjelde har jeg ikke iagttaget; heller ikke har jeg kunnet paavise noget Sammenheng mellem Kalv- ning og Tidevande. Kalvning indtraadte saavel, naar det var Hojvande, Lavvande, Slaptid og Springtid. Hvis Kalvningerne hidrorer fra Opdriftens Virkning, skulde man vente de fleste 175 Kalvninger, naar det var Hojvande og da navnlig Springtid; men noget saadant har jeg ikke kunnet paavise. Derimod var det meget almindeligt, at en ringe Nedstyrtning var Signalet til be- tydelige Nedstyrtninger i Nabolaget, hvilket ogsaa er forklarligt nok, da Spaltedannelsen fremmes ved den opstaaede Rystelse. At Kalvningerne til Tider kan vere meget heftig i Isfjordene, har ogsaa andre bemerket. For Sarkardlek-Gletscher er der neppe noget, der taler for anden Maade at kalve paa end ved Nedstyrtning. | Den Kalvis, der dannes, er meget ubetydelig og forsvinder — naar undtages nogle enkelte Knolde — i Lobet af faa Dage. Paa Gletscherens Overflade nogle faa Meter fra Land iagt- tager man de af Nordenskiöld forst omtalte Kryokonit- Cane Fig. 4. huller. Foruden disse lodrette Kryokonithuller havde jeg Lejlighed til at iagttage, hvad de tyske Glacialgeologer kalder Sonnenlöcher (Solhuller), om hvis Forekomst i Gron- land der vist ikke foreligger nogen Beskrivelse. For det meste var disse Huller temmelig store (henved 1 dm) og aldrig kredsrunde, men altid mere eller mindre nyredannede. Jo mindre i Tvermaal des mere nermede de sig til at vere kreds- runde — omtrent som Figuren viser. Samtidig med, at de nerme sig til at vere kredsrunde, gaa de over til at blive lod- rette. (Fig. 4). De nyredannede Huller var altid orienterede paa en be- stemt Maade, nemlig saaledes, at et lodret Plan gennem Aksen faldt sammen med Meridianplanet; denne bestemte Orientering holdt altid Stik. Selve Aksen, der peger mod Syd, danner en Vinkel paa c. 50° med Lodlinjen. (Fig. 5). 176 I Bunden af disse skraatstillede Huller fandtes, saa vidt jeg kunde skønne, nøjagtig det samme Slam som i de smalle, lodrette Huller. Der kan derfor næppe være Tvivl om, at de maa have samme Oprindelse som de Nordenskiöld- ske Kryokonithuller. Med Hen- syn til den skraa Stilling af Hullerne er at bemærke, at denne ikke hid- rører fra Bevægelsen af Gletscheren, i saa Fald maatte man kunne paavise en Overensstemmelse i Orienteringen og Hovedretningen af Bevægelsen i Fig. 5. Gletscheren. Den skraa Retning kan heller ikke fremkomme ved Forskellen i Bevægelseshastighed i de forskellige Lag af Gletscheren. Da Hullerne ikke er mere end 1 à 2 dm dybe, vil der ikke der kunne være nogen væsentlig Forskel i Bevægelseshastighed. Da Hullerne altid er orienterede mod Syd, maa den skraa Stilling sikkert hidrøre fra Solstraa- — lerne. Hvorledes disse store Kryokonithuller opstaar, er usikkert; maaske opstaar de ved, at flere smaa og tætliggende Kryokonithuller smelter sammen. Som bekendt opstaar Kryokonithullerne ved, at Støv, der er blæst ud fra Land, opsuger Varmestraaler og derved smelter sig Fordybninger i Isen. For at forklare, hvorledes det gaar til, at Hullerne bliver skraa, maa man antage, at det Støv, der ligger ved den sydlige Kant, ligger i Skygge og derfor ikke smelter sig ned; derimod vil det Støv, der ligger i den nordlige Del af Hullet træffes af forholdsvis mange Solstraaler og derfor smelte sig ned i Isen. Hullernes Nyreform staar sikkert i Forbindelse med Solens daglige Bevægelse. Om Eftermiddagen, f. Eks., vil det Støv, der ligger ved den sydvestlige Kant af Hullet, være i Skygge. De store Kryokonithuller har jeg kun fundet i Nær- heden af Land, formodentlig fordi der i Nærheden af Land af- lejres saa meget Støv. 177 Sarkardlek-Gletscher er temmelig bred, men Megtig- heden er næppe stor. Midt i Gletscheren (se Kortet) ligger der en ret stor Nunatak, fra denne gaar der en Morenestribe ud til Gletscherenden. Den Mengde Materiale, denne Morene- stribe indeholder, er dog ikke meget betydeligt. Foruden denne fra Nunataken kommende Morenestribe, findes der en Morene til; den kommer fra en lille af Gletscheren overdækket Fjeld- knold. Denne Morenestribe er noget rigere paa Materiale end den fer omtalte. Gletscherenden danner en lige Linje fra Sydsiden til Nuna- taken, herfra og til Kavdlunap-Nuna danner den en Bue og er tillige ganske lav. Øst for den omtalte Morenestribe hæver Gletscheren sig op i en lav Kuppel og er paa dette Sted meget sonderreven. Forovrigt er Overfladen i det hele meget ujevn. Hovedretningen af Spalterne i Gletscherne gaar vinkel- ret paa Bevegelsesretningen af Gletscheren; men foruden disse Hovedspalter er der ogsaa andre mindre fremtredende Spalter, der hidrore fra Ujevnheder i Undergrunden. Saavel langs Gletscherens nordlige som dens sydlige Rand flyder der en Smeltevandselv. Den paa den sydlige Side er langt den storste. Under mit Ophold her inde i Fjorden foretog jeg nogle meteorologiske lagttagelser; selv om de ikke er systematisk gennemførte, meddeler jeg dem dog: PAUL: | 8. Aug. | 9. Aug | 10.

Derimod foretog jeg ingen Hastighedsbestemmelse af Glet- scheren, da jeg ikke kunde skaffe en Basis, der laa hejt nok til, at jeg kunde faa gode Sigter ud over Gletscheren. For at faa udfort nogle Lodskud i Nunatap-Tasia lod jeg Konebaaden bere over fra Kekertarssunguit-Ilua til den lille Ferskvandsso Amitukujok og derfra atter over til Nunatap-Tasia. Amitukujok er forholdsvis flad — det dybeste Lodskud var kun 14 m. Den Dal, Soen ligger i, er en Bruddal, ud- foret af Morænemateriale, idet nemlig Dalens Retning gaar vinkelret paa den Retning, Isen maa have haft, da den sked sig ud over Yderlandet. Paa lignende Maade forholder det sig temmelig sikkert ogsaa med Kunguak-Dal, der jo er parallel med Amitukujok. Nunatap-Tasia var derimod meget dybere. I den ost- lige Del, hvor den aabenbart er dybest, belob Maximumsdybden sig til 127 m. Soens Dannelse skyldes vistnok i forste Instans Forvitring, paa lignende Maade som jeg senere kommer til at omtale det for Itivdlek’s Vedkommende. Men Forkastninger har sikkert ogsaa haft deres Andel i Dannelsen; paa Hammers Teltplads- knude lige vest for Soen er der et Par Steder Dale, der maa opfattes som Bruddale, og som ligger temmelig noje i Ret- ning af Nunatap-Tasias Hovedretning, ligesom man kan forfolge en Forkastning her fra Nunatap-Tasia helt hen til Tasiussak (Kajuta sugdlua). Det er netop denne Forkast- ning, der danner den Randkæde der — afbrudt af Forkastnin- ger i Nord-Syd — lober langs den sydlige Side af Jakobs- havns-Isfjord, og hvoraf Nunataken er en Del. Naar den ostlige Del er dybest, skyldes det maaske den Omstændig- 179 hed, at to Forkastningslinjer her skærer hinanden, nemlig For- kastningslinjer i Ost-Vest og den Forkastningslinje, der har dan- net Amitukujok-Dal. Under den højere Stand af Indlandsisen, gik denne ind gennem Nunatap-Tasia og har yderligere eroderet den. Fra Vestenden af Nunataken ved Varden var det let at konstatere, at Gletscheren nu laa lengere ost paa end i Juli. Medens Gletscherenden af Sarkardlek for det meste stiller sig med fremadheldende Endeflade, saa staar Enden af Jakobs- My Mn Fig. 6. havns-Gletscher altid med lodret Veg eller maaske snarere med Veggen lidt tilbageheldende. Undertiden blev det ned- styrtede staaende paa Halvvejen, hvilket jeg ogsaa lagde Merke til 1902. Dette beror sagtens paa, at saadanne storre Stykker kommer til at hvile paa megtige Masser af sammenstuvet Kalvis, der bærer dem oppe. Muligvis hidrorer Fænomenet ogsaa fra, at den Del af Stykket, der rager ned i Vandet, af dette bliver delvis opløst, saaledes at Opdriften bliver mindre. Hosstaaende (Fig. 6) søger at anskueliggøre dette Forhold. ndre Kalvninger end saadanne Nedstyrtninger fik jeg ikke 180 Lejlighed til at iagttage. Derimod bemærkede jeg paa selve Gletscheren inden for Enden ruinagtige Partier 9: Omraader hvor Spidserne tilsyneladende var faldet ned. Saadanne Partier var ved deres hvide Farve afstikkende i Forhold til den graa Farve, der ellers er herskende paa Gletschernes Overflade. Paa Ostenden af Nunataken var der god Lejlighed til at paavise, at Isen havde trukket sig tilbage. Isranden laa nu 35 m lavere, end den har gjort tidligere, idet dens tidligere Stand jo markeres af en Morene, endnu kun sparsomt bevok- Nu 10 \ is Fig. 7. set med Planter. Isens overste Rand laa i en Hojde af 195 m, dens Fod i en Højde af 175. Gletschervæggen var altsaa 20 m høj. Mellem den øverste Moræne og den nuværende Isrand, der iovrigt ikke er ledsaget af nogen Morænevold, iagttog jeg flere mere eller mindre udpregede Morenevolde: Beviser for, at Isen ikke kan have trukket sig jevnt tilbage, men i lengere eller kortere Tid har været stationær, hvor nu Moræne- voldene ligger. Mellem den ostlige Ende af Kekertarssunguit og Nunatanguak skyder der sig en Gletscher ned. Den er 181 ganske jævn oven paa, og nogen videre Bevægelse kan der næppe være i den. Formodentlig ligger den i Læ af Nuna- takens Fortsættelse under Isen mod Ost. Ogsaa denne Glet- scher er i Tilbagegang, hvilket de temmelig friske Morener, der ligger langs dens Rand, tyder paa. Ved Enden af Gletscheren er der et Delta, som forener sig med en Gletscherelv, der lober mellem Nunatanguak og Fastlandet, og som kommer fra en bred Gletscher, der skyder sig ned mellem Nunatanguit og Ekaluit-Nunata; ogsaa her har Isen trukket sig meget sterkt tilbage. Tempera- turen i Elven Kl. 2 de sidste Dage i August var nojagtig 1°; om Natten danner der sig Tyndis paa den Del af Nunatap- Tasia, hvor den munder ud. Mængden af Slam den forer, er ikke stor. En Bestemmelse gav kun 6 gr pr. Liter. Her, hvor Deltaet løber tæt under Gletscherenden, vasker den de nederste Dele bort, og det ovenoverliggende styrter da ned. Gletscherenden kommer derfor til at staa med lodrette Vegge ganske som de Gletschere, der gaa ud til Vandet i Fjordene. Det synes mig, som dette Forhold giver et Finger- peg til Forstaaelsen af Kalvningen i hvert Fald for Gletschere, hvis Hastighed ikke er stor. Paa Hammers Kort kaldes den Landstrekning, der ligger inden for den store Gletscher og hen imod Ekaluit-Nunata, for Tivsarigsok (Ире = Lugt, sak og gigpok). Oprindelig betegnede Helland hermed Strekningen ved Kangerdlu- kasik. Hammer flyttede det lengere mod Ost. Gronlendere, som jeg spurgte ud om Stedbetegnelsen paa Landstrekningen her, kendte ikke dette Navn. Overhovedet har de ikke nogen Betegnelse netop for dette Omraade. Der maa formodentlig have indsneget sig en Misforstaaelse, hvilket forøvrigt meget let kan ske med gronlandske Stednavne, idet disse jo i Modsæt- ning til Stednavnene i ældre Kulturstater har en Betydning, der forstaas umiddelbart, og forskellige Gronlændere ofte "betegner 182 et og samme Sted forskelligt, efter hvad hver af dem synes, er det mest karakteristiske for det. Paa den vestlige Del af Nunataken opholdt jeg mig meget for at faa Lejlighed til at iagttage Kalvninger af Glet- scheren. Smaa Kalvninger, Losning af Flager og Nedstyrtnin- ger var hyppige nok, men storre Kalvninger, der kunde give nogen nermere Oplysning om, hvorledes de store Isfjelde dannes, fandt ikke Sted, medens jeg var til Stede. Der stod endnu tilbage, inden Vinteren kom, at foretage en kort Ekskusion til Alangordlek-Gletscher — Ser- mia alangordlia,- — som Grønlænderne kalder den. Efter de Lodninger, som jeg foretog, — se Kortet — er Dybden i Midten kun c. 50 m, langsomt aftagende ind mod Bredden. Hojden af Gletscheren fandt jeg at vere 25 m eller i kompakt Masse 20 m. Hvis Gletscheren skulde зуотте i Vandet med sin Ende, — eller i hvert Fald vere lige ved det — maatte Fjorddybden belobe sig til c. 150 m. Man kan naturligvis an- tage, som jeg ogsaa gjorde det for Sarkardlek, at en ret betydelig Endemoræne befinder sig ved Enden af Gletscheren. En Endemorene paa 100 m er jo ret betydelig; men Forhol- dene ved Keakusuk synes mig at tale noget til Gunst for en saadan Opfattelse. Bunden baade her og i Sarkardlek-Fjord bestaar af et meget fint Ler; kun i Nærheden af Gletscheren viste Bund- proverne sig mere sandede. Dette forklares ved, at den be- tydelige Strom af Smeltevand forer Leret bort, og lader Sandet ligge. Forevrigt gaar Hovedmassen af Smeltevandsstrommen op langs Gletscherenden og driver derefter langs Overfladen af Fjorden ud efter. Ved at skovle i Overfladen kan man jævnlig faa det blaa, næsten klare Fjordvand at se. Kalvningerne i Alangordlek frembyder ingen Forskel fra Kalvningerne i Sarkardlek; men Gletscheren er endnu mindre produktiv end Sarkardlek-Gletscher. Paa begge Sider af Gletscherne laa der ret betydelige Ende- 183 morener; men forøvrigt var der intet, der tydede paa, at denne Gletscher var i nogen stærk Aftagen. Paa Endemorænerne var Papaver nudicaule, Stellaria alpina og enkelte andre indvandrede. Fra det høje Land nord for Alangordlek-Gletscher, har man en fortrinlig Udsigt over Gletscherne. Navnlig kan man meget tydeligt forfølge Spalterne i Gletscherne. I det hele gaar de paa tvers af Bevegelsesretningen. Afvigelserne beror paa Ujevnheder i Undergrunden. Er der en Bakke under Isen, hemmes Isens Bevegelse paa det Sted, og Spalterne kommer derfor til at lobe skraat tilbage. Fra Alangordlek-Fjord hever Landet nord for sig meget brat. Naar man ferst naar op, er det meget jævnt, idet, saa vidt man kan skonne, de oprindelige Dale er blevet ud- fyldt af Morænemateriale. Op over Plateauet hever der sig mod Nordost et kegledannet Fjeld, Omerslusat. Fra Alangordlek roede vi til Ekaluit (Laksene). en i Laksetiden besogt Teltplads ved den Elv, der lober ud fra Ekaluit-Tasia (Laksesoen). De mange primitive Rogestil- ladser er et Vidne om Virksomheden. Forevrigt er Laksene smaa og heller ikke velsmagende. Umiaken blev baaret langs den nordre Bred til Seen og sat i Vandet her. Om Efteraaret staar Vandet næsten en Meter lavere end om Foraaret. Da Soen modtager Tillob fra Smeltevandsfloder, der kommer fra Indlandsisen, ег Vandet uklart ligesom i Nunatap-Tasia, og ligesom der er Bredden fuld af skarpkantede Sten, som gør det besverligt at sætte en Konebaad i Vandet. Paa en gammel Morenevold paa den nordostlige Side af Seen slog vi Telt. Desværre fik jeg ikke udfort nogen Lodning, da jeg ved et Uheld havde mistet Lodlinen i Alangordlek. Formodentlig er Seen temmelig flad i Modsætning til Nunatap-Tasia. Medens Nunatap-Tasia i en forholdsvis sen Tid har veret udfyldt af en Ismasse, der banede sig Vej syd om Nunataken, saa har Ekaluit-Tasia ikke veret udfyldt af Is, siden denne havde en langt betydeligere Udbredelse end nu. 184 Ved den ostlige Ende af Soen lober.der en Gletscherelv ind. Bekken har skaaret sig ned i et tidligere Delta. Dette maa altsaa vere dannet under en højere Stand af Søen. Sar- kardlek- og Alangordlek-Gletscherne har formodentlig i sin Tid skudt sig frem, saaledes at de helt har stemmet Ekaluit-Tasia op. Rudimenter af det tidligere Gletscher- delta staar tilbage som Kamme og Rygge. Elvedalen er flad og fuld af Rullesten. Ost for Søen oppe paa et Plateau hæver det for omtalte Omerslusat-Fjeld sig; det ligger tet ude ved Indlandsisen, og man har derfra en udmerket Udsigt i alle Retninger. Des- verre sneede det, saaledes at Landskabet blev indhyllet i Sne; det blev derfor vanskeligt at erkende Grensen mellem Land og Indlandsis, altsaa at paavise, om Isen overhovedet havde trukket sig tilbage. Paa nogle enkelte Steder kunde jeg dog paavise, at der laa store nye Morænevolde; det maa vel derfor være berettiget at antage, at ogsaa Isen her er i Aftagen. Langs Isranden laa der opstemt mange Smaasøer; i adskellige af disse ender Isen med lodrette Vægge. Paa Isen laa der ret betydelige Moræner. Egnen indenfor Ekaluit-Tasia er øde og besøges yderst sjældent af Grønlænderne og kun om Vinteren ved Hjælp af Hundeslæde, naar de vil paa Rensdyrjagt. Man kører ind ad Tasiussak til Kangerdlukasik og over Tangen ind paa Ekaluit-Tasia. Derpaa følger man den før omtalte Glet- scherelv mod Nord og kommer saa ind paa Ekaluit-Nuna- tap-Tasia (ikke at forveksle med Kekertarssunguit Nuna- tap-Tasia). Rensdyrene er dog meget sjældne. Ganske vist har jeg flere Gange i Egnene syd for Isfjorden set Rensdyrspor, men kun en eneste Gang i.Sommeren 1902, set et ungt Dyr. Forøvrigt er ogsaa andre Dyr sjældne herude, saaledes baade Hare og Rype. Nordøst for Søen strækker der sig en temmelig høj Bjerg- kæde, fra hvis højeste Top man har en udmærket Udsigt. Man 185 ser over Jakobshavns-Gletscher til Nunatarssuak og dennes Ostspids; man kan ligeledes se Dele af Ekaluit- Nunatap-Tasia og Ekaluit-Nunatä. Disse topografiske Enkeltheder er blevet indfort paa Kortet. Ost for Seen findes et lille Omraade af Fjeldskraaninger, der ikke er bevokset med Lav, og som derfor er lysegraat. Rimeligvis har Isen for nylig med en Tunge hængt ned herover. Stedet synes ogsaa at være antydet paa Hammers Kort. Da Søen ligger saa aaben, er Vegetationen meget sparsom, selv paa Nordsiden, der dog beskyttes af de ovenfor omtalte Fjelde. Nogle enkelte Steder er dog Birkebuskene ret godt ud- viklede, og i en Fure, som en lille Elv havde skaaret i en Endemoræne, der strakte sig langs den nordlige Del af Søen, voksede Salix glauca oprejst og naaede en Højde af 1.3 m. En Skare Rødirisker holdt til i dens Grene. Vegetationen paa Morænen var, saaledes som det altid er Tilfældet, meget spar- som. Mest fremtrædende var den sorte traadede Liken, dernæst enkelte Græsser og Halvgræsser, hist og her en Dryas, Saxi- fraga tricuspidata, Silene acaulis og endnu sjældnere nogle Eksemplarer af Salix glauca og Betula nana. Efter et have faaet et foreløbigt Overblik over Egnen om- kring Ekaluit vendte vi tilbage til Ekaluit-Tupersua. Næste Morgen var Alangordlek saa langt, som vi kunde se, tillagt med Tyndis. Grønlænderne blev naturligvis noget be- kymrede ved Situationen og ønskede at komme af Sted, saa snart ske kunde. Med Aarerne slog vi Isen itu og kom om- sider ud i aabent Vand i Tasiussak. Her viste Vandet en Temperatur af 1.2”. Det kolde Smeltevand i det indre af Is- fjorden fremmer selvfølgelig i høj Grad Islæget. Om Aftenen naaede vi Kekertarssunguit-Tuperssua, hvor vi slog Telt. Den følgende Dag gik jeg over Kekertarssunguit- Kulå til Teltpladsknuden for at iagttage Forandringer i Isfjor- den. Der var forøvrigt ikke noget interessant at opdage; det tidligere omtalte Isfjeld i oprindelig Stilling var forsvundet. 186 Derefter fortsatte vi Rejsen ud af Tasiussak, idet vi dog anløb Upernivik ved Tasiussaks Udmunding i Isfjorden. Her gik jeg op paa Fjeldene for at se, om det eftersøgte Is- fjeld skulde vere at se. Det var der ikke og maa altsaa vere gaaet i Stykker; ud af Fjorden kan det i hvert Fald ikke vere kommet. Da nogle meteorologiske Observationer fra Egne, der ligger ner Indlandsisen maaske kan have sin Interesse, meddeles her nogle Fragmenter. Nunatap-Tasia 25. Aug. | 26. Aug. 27. Aug. 29. Aug. | 30.

Som omtalt af Hammer er Indsejlingen meget snæver og kan kun foretages i Nærheden af Middelvand- stand og endda kun med Forsigtighed, Selve Udlebet har skaaret sig igennem en Moreneaflejring, der, da den er flad ovenpaa, synes at vere afsat under Vand. Konebaadsstyreren var forovrigt ukendt her, og da vi sogte at naa frem ad den sydlige Arm, lob Baaden paa Grund, hvorover Styreren blev meget betænkelig. Vi vendte og slog Telt paa Akuliarusek, hvorfra man har en ganske god Udsigt over de Gletschere, der skyder sig ned. Flere Forhold tyder paa, at Isen var i Aftagende. Paa Grund af det snævre Indlob beløber Forskellen mellem Flod og Ebbe sig kun til en halv Meter i Pakitok-Ilua. SOE 13 188 Da Vejret vedblev at være godt, og Konebaadsstyreren ikke var bange for at slaa Telt i rimelig Nerhed af Isen, sejlede vi ind gennem Ata-Sund og slog os ned i Bassinet syd for Torsukatak ved Kugssuak, en Gletscherelv, der kommer fra en Gletscher mellem Nunap-Kigdliga og Manitok. Gletscheren styrter fra en Hojde af 350 m meget stejlt ned mod Kugssuak-Dal. Paa denne Tid forte Elven ikke ret meget Vand og var desuden delt i flere Arme, saaledes at man uden større Besvær kunde komme over den. Nunap-Kig- dliga bestaar af Glimmerskifer, der er stærkt forvitret. En gammel Morene forteller, at Isen har staaet mere fremrykket end nu. Men ellers kan man ikke sige, at Isen nu for Tiden har trukket sig synderligt tilbage; hvis man overhovedet med Sikkerhed kan tale om Tilbagegang her. Paa Plateauet vest for Kugssuak ligger der adskillige Seer, hvorfra Elvene styrter ned som brusende Vandfald. Ved Teltpladsen laa en subfossilforende Lermasse. Mellem Gneisoen og Fastlandet har den bevaret sig mod Denuda- tionen; Bolgeslaget har dog gnavet den sterkt. Paa Klippe- siderne ser man smukke Gletscherskrammer. Disse er hyppigt krydsende. Selv om man nodvendigvis maa antage, at Ismas- sen i umiddelbar Nerhed af Gletscherskrammen maa_ have samme Retning som Skrammen, og at altsaa Ismasserne ved Bunden ved krydsende Skrammer maa have haft en forskellig Retning, saa er det dog ikke vist, at hele Ismassen helt op til Overfladen har haft forskellige Bevegelsesretninger. En sterre Megtighed af Isen er vistnok tilstrækkelig til at kunne frem- kalde en forskelligartet Bevegelse af Ismasserne ved Bunden. Paa Gletscheren stod Vandet frosset i Fordybningerne og faldt ved sin asurblaa Farve stærkt i Øjnene. Langs Glet- scheren, men dog fjernet nogle Meter derfra, laa en ældre Mo- rene, sparsomt dekket af den Vegetation, man sædvanlig tref- fer paa gamle Morener. Umiddelbart langs Gletscheren laa der en anden ganske frisk Morene. 189 Den Del af Nunap-Kigdliga, der stoder op til Gletsche- ren, frembyder en smuk Lagrekke. Nederst iagttager man en typisk Gnejs tet gennemsat af Pegmatitgange. Derefter kommer der et Lag Hornblende og endelig averst et Glimmer- skiferlag; dette sidste er stærkt forvitret. Lagene falder mod Øst. Fra vor Teltplads her ved Niakornanguak formaaede jeg Styreren til at sejle os til Nunataken. Denne har gan- ske samme Lagfolge som Nunap-Kigdliga; dog er der ved et Brud, der gaar tværs over Nunataken i est-vestlig Retning, betydelig Forskel paa den nordlige og sydlige Del af Nuna- taken. Den nordlige Del er meget hojere end den sydlige Del, og da Lagene falder mod Øst, er den ved Forvitring delt i Trappetrin, der lober i Nord-Syd, og som ger Marchen meget besverlig. Uagtet Nunataken i og for sig ikke er videre stor, tog det en uforholdsmessig lang Tid at naa op paa det hejeste Punkt. Herfra har man en udmerket Udsigt til alle Sider. Her tet ved Toppen fandt jeg et stort Rensdyrgevir. Det var meget forvitret og stammede sandsynligvis fra den Tid, da Rensdyrene fandtes i disse Egne. Nu er Rensdyrene udryd- dede paa Strekningen mellem Torsukatak og Jakobshavns- Isfjord. Landstrækningerne her er jo ogsaa kun smaa, og Kysten er tæt befolket — efter grønlandske Forhold naturligvis. Men allerede umiddelbart syd for Jakobshavns-Isfjord og nord for Torsukatak findes der Rensdyr, paa det sidste Sted er de endog ret hyppige. Da Dagene nu allerede var korte, kom vi først hjem sent om Aftenen. Heldigvis var det Maaneskin, ellers havde vi været nødt til at tilbringe en ret kølig Efteraarsnat paa Klipperne; nu kunde vi med lidt For- sigtighed langsomt bevæge os ned ad. Den sydlige Del af Nunataken bestaar i sin øverste Del af en stærkt forvitret Glimmerskifer ganske som paa Nunap- Kigdliga, og ligesom paa denne var Overfladen temmelig jævn og fuld af Forvitringsprodukter. Sermia-Kujadlek-Dal,' 1 190 saa vel som Brudlinjen mellem den nordlige og sydlige Del af Nunataken samt Sermia-Avanardlek-Dal hører for- modentlig alle til samme System af Forkloftninger. De to Glet- cherdale er sterkt eroderede, derimod staar Bruddalen paa Nunataken med skarpe Former og er fuld af Forvitrings- produkter — nedfaldne og skarpkantede Sten og lignende. Lagfolgen er meget regelmæssig: nederst Gnejs, saa Horn- blende, saa Glimmerskifer; kun paa den nordlige Del af Nunataken har et overste modstandsdygtigt Lag holdt sig; derfor er ogsaa dette Parti det hojeste. I Dalen mellem den nordlige og sydlige Del af Nuna- taken lober der baade en lille Elv, der kommer fra Plateauet, og en Gletscherelv, der kommer fra en lille Gletscherse, af Gronlænderne betegnet Tasek-Ilulialik (tasek = So, iluliak = Isfjeld, lik == forsynet med), fordi der dannes smaa Isfjelde i den — formodentlig paa sædvanlig Maade ved Nedstyrtning. Isen er her i Vinklen mellem de to Dele af Nunataken meget jevn ganske som ovenfor Nunap-Kigdliga. Uader Opholdet her inde i Bassinet syd for Torsukatak, havde vi i Forhold til Aarstiden et ualmindeligt mildt Vejr. Dette beroede paa, at Vinden stadig var ostlig-sydestlig, saa- ledes at Vinden var en Fohnvind, til Tider endog udpreget med hej Varme og sterke Vindsted. Men nu gik Vinden om til syd og samtidig faldt Temperaturen. Vi forlod Nunataken for at sætte over til Anä-Land, for at jeg kunde faa Lejlighed til at studere Sermia-Avanardlek; vi passerede flere lave Øer, Satut, (de tynde 9: de flade); den nordligste af dem, Kekertak-Avanardlek, bestaar af to Gnejshoje, forbundne ved en Morene. Vi slog Telt ved Niakornak (niakok — Ho- vede). Med Omslaget i Vejret kom Taage, og om Natten faldt der megen Sne; nu var det pludselig blevet Vinter. Vi blev derfor enige om, at nu var det bedst at bryde op og naa ud til Kysten, inden Tyndisen kom og sperrede for os. Paa Vejen "tilbage passerede vi syd for Kekertakasak en lille ©, Poki- 191 tokujök (pokitok, lav); den var langstrakt og bestod ligesom den nylig omtalte Kekertak-Avanardlek af to Gnejshoje, forbundne ved Morenemateriale. Denne @ ligger saa lavt, at Vandet ved Springflod gaar over Forbindelsespartiet. Hvis Landet sænker sig saa hurtigt som formodet, maa denne ©, ved at Tangen bliver overskyllet, snart blive delt i to. Da vi kom til Torsukatak, laa der vidt og bredt Tyndis. Vandet er jo i Forvejen afkolet til Frysepunktet; falder der saa Frostsne, fryser Kalvisstykkerne let sammen. Vi var imidlertid forberedt paa disse Vanskeligheder og havde taget tynde Bred- der med. Disse blev fastbundne paa Umiaken i Vandlinjen, saaledes at [sen skar paa Brædderne, medens Skindet blev be- skyttet. Vi naaede derfor uden større Besvær Kekertak. Medens vi sejlede gennem Torsukatak, sprang en tid- ligere Strandlinje meget tydeligt frem navnlig paa den sydlige Side. Paa min tidligere Rejse gennem Torsukatak havde jeg ikke faaet Øje paa den; men Sneen bevirkede nu, at den traadte tydeligt frem. Paa Slæderejserne den kommende Vinter kunde jeg næsten allevegne i Torsukatak paavise Strandlinjen. Paa den nordlige Side af Fjorden var den dog kun tydelig med bestemt Belysning. Saa vidt jeg ved, er Dr. Steenstrup den eneste, der tidligere har paavist, at man ogsaa andre Steder i Grønland kan paavise saadanne Strandlinjer, der i Norge er ret almindelige. ; I Kekertak købte jeg Hunde, og med disse sejlede vi den følgende Dag (d. 6. Okt.) til Ritenbenk, hvor jeg blev boende til den 31. Januar. Da vi var kommet til Ritenbenk, brød der en heftig Sydvest-Storm løs, ledsaget af et stærkt Snefald. Men efter en Uges Forløb var Vejret atter smukt, og Sneen forsvandt næsten ganske igen. løvrigt var Efteraaret ikke koldt. Gennemgaaende havde vi en Temperatur af — 8° fra midt i Oktober næsten til Udgangen af December. En Om- stændighed, der forøvrigt havde den kedelige Virkning, at jeg ikke kunde komme af Stedet, eftersom Islæget udeblev. 192 Da Ritenbenk ligger paa omtrent samme Bredde som Ana, havde jeg efterladt nogle Termometre hos en Fanger der, for at han i Efteraarsmaanederne skulde foretage Temperatur- aflesninger. Det vilde jo vere af Interesse at sammenligne Temperaturerne ved Indlandsisen og ude ved Havet. For at der ikke skulde ske nogen Misforstaaelse, havde jeg anmodet en gronlandskkyndig Mand om at forklare Fangeren Fremgangs- maaden. Da jeg senere kom til Anä, viste det sig, at Manden nok havde opskrevet nogle Tal, men disse var uden Verdi. Da Forstaaelsen af Gronlændernes Betegnelse for Vind- retningerne kan vere af Betydning for Rejsende, meddeles her nogle Oplysninger, som sikkert yderligere kan suppleres og maaske modificeres. Vindretningerne i Gronland bliver stedse af Gronlænderne angivet ved den Retning, hvorfra de komme. Da Grønlænderne jo ikke har noget andet Middel end et Jugement af Solen til at bestemme Verdenshjernerne, bliver Retningerne naturligvis altid helt retvisende. Efter at Kompasset har fundet Indgang blandt Grønlænderne, angives nu ogsaa Vindretningerne mis- visende. Mange Steder benyttes naturligvis lokale Navne for de fremherskende Vinde. Som Følge af Insolationen om Dagen og den stærke Ud- straaling om Natten er Land- og Søvinde meget almindelige i Grønland. Landvinden — altsaa i Reglen den østlige Vind — bliver kaldt Asarnek (af en mig ubekendt Rod) og de sæd- vanlige Søvinde (Vestvinde) Imarsarnek (af Imak — Hav). Af de Vinde, der opstaar ved større barometriske Minima, er Norden- og Søndenvinden de vigtigste. Nordenvinden hedder Avagnak, men Retningen er egentlig nærmest nordvest (ret- visende). Den rigtig kolde Nordenvind betegnes Avanakasik (Avanak — Norden og kasik — ussel, forbandet). Misvisende bliver Avanakasik altsaa nordost, Avanak derimod nord. Sydlig Vind betegnes Kigangak (misvisende altsaa. sydvest); i Syd-Grønland betegnes denne Vind Nigek. Kujasik er en 193 sydlig Vind, der stryger langs Kystens Hovedretning, altsaa en sydostlig Vind (misvisende Syd). De varme Fohnvinde, blev saa vidt jeg forstod, kaldt Kiangnak (af Kiak = Varme) eller Isangiak, naar man serlig vilde betegne Fohnvinden. Dan- skerne i Grønland kalder Fohnvinden Sydost (misvisende). En lokal Vind, der bleser gennem Vaigat kalder Gron- lenderne Isersarnek, de Danske Vaigatsnorden. Det er en svag Vind, der bringer smukt Vejr; den samme Vindretning kaldes Avanak-utokak, naar det blæser stærkere, og Vejret er enten taaget eller nedborbringende. Begge Vindretninger er altsaa nordvestlige, men medens den forste vistnok oprindelig er en Nordvind, er Avanak-utokak vistnok en vest sydvestlig Vind, der stryger rundt om Disko ned gennem Vaigat og derved faar Udseende af at vere en nordvestlig Vind. Det er blevet mig meddelt, at denne vestlige Vind andre Steder kaldes Avangnak-kananek. Kananek betyder egentlig en syd- vestlig Vind. Nordenvinden, der stryger ned gennem Ata- Sund (paa Gronlandsk Ikarasak), kaldes af Beboerne der om- kring Ikarsarnek. En nordlig Vind, der stryger ned over God- havn, gaar der under Navnet Pitorak. Forovrigt har Vindene de forskellige Steder vistnok oftere Navne efter Fjelde eller Dale, som de stryger hen over; ved Kristianshaab kaldes Fohnvinden Sarkarsnek efter de hoje Fjelde mod Syd (Sarkak — Sydside). I den mig af Commissionen for Gronlands geologiske og geografiske Undersøgelser givne Instruks blev min Opmerksom- hed henledet paa Dannelsen af Isfoden og dennes Indflydelse paa Tangranden. Under mit Ophold i Ritenbenk havde jeg netop god Lejlighed til at iagttage, hvorledes Isfoden anlægges. Isfod betegner den Del af Isdækket paa Havet, der er fast- frosset til Kysten. Om Vinteren danner den en Bræmme paa en, to eller flere Meters Bredde, alt efter Kystens Form; jo fladere Kysten er, des bredere er Bræmmen. Den fremkommer ved, at Isdækket under Flod og Ebbe hæver sig op og ned; kun en Isrand langs Land ligger fast. Det bevægelige Isdække 194 er skilt fra denne Rand ved Spalter. Ved Lavvande særlig under Springtid kan Isdekket ligge saa lavt, at det er meget besverligt at komme i Land; man maa ligefrem med Tok’en hugge Trappetrin i Isfodens Kant; med Hundeslede er det endnu besverligere. | Begyndelsen af Vinteren ved stejle Strand- bredder kan der mellem Isfoden og Isdækket ved Lavvande og navnlig under Springtid ligefrem vere en aaben Rende af Vand (se Fig. 8c). Saaledes maatte vi i Februar en Aften vente i flere Timer paa en Klippeside, inden vi kunde slippe ned paa Isen, ellers vilde vi let i Morket vere faldet ned i Renden. Isfodens Anleg finder Sted endnu for der har dannet sig Isleg — fra Isfjordene ses der her bort. — Den begynder som et tyndt Glassurovertrek paa Bredden, naar det er Ebbe og naar fra Hojvandets overste Stand til omtrent laveste Ebbe. Naar Vandet igen stiger, bliver den nederste Del af Over- trekket igen oplost, hvilket jeg overbeviste mig om ved at fole efter, dog finder denne Opløsning ikke Sted straks, men noget efter, at Vandet er steget. Paa de overste Dele maa der aabenbart ogsaa oploses noget — men ikke saa meget som 1 den nederste Del, fordi Vandets Indvirkning er meget kortere. Naar Vandet atter falder, fryser der en ny Skorpe fast, og — hvilket der vistnok er det vesentligste — Skorpen bliver sterkt afkolet saaledes, at naar Vandet stiger, vil en Mængde Vanddele fryse fast. I den nederste Del vil dog Vandet kunne faa Tid til at tilfore saa megen Varme, at en Del atter oploses. Den overste Del af Isfoden vokser derfor stærkere end den nederste. Derfor danner Isfoden ikke en Figur som (b) men snarere som (c). (Fig. 8). Naar Isen om Foraaret forsvinder, driver bort, ligger Is- foden tilbage som en Bremme med nesten stejle Rande. Men dette varer kun kort, thi Vandet, der nu, da Isdekket er borte, kan komme i Bolgebevegelse, vil snart gnave sig ind, saaledes at Isfoden kommer til at se ud som (e) og senere som (f). Jeg har aldrig iagttaget, at Isfoden er brækket los fra Klippen; derimod har jeg iagttaget, at dens yderste Spids kan brække 195 af (den punkterede Linje paa Fig.f), naar det er Ebbe, og naar den underste Del af Isfoden er gnavet bort. Ved Kristianshaab havde jeg Lejlighed til at iagttage, hvorledes en Fucus, der sad indfrossen i Isfoden, blev fuldstendig fri, uden at den mistede saa meget som en Flig. Dens morke Legeme absorberer Varme- straaler saaledes, at der omkring den dannes Vand. Selv om der skulde ske et Brud, vil den derfor knapt nok en Gang blive beskadiget. Naar en stor veludviklet Alge ikke odelegges af Isfoden, saa finder dette endnu mindre Sted med smaa Alger, dé omde Miadivande Kawvomde Hovis Fig. 8. hvilket mine lagttagelser ved Øerne ved Kristianshaab synes at bekræfte. Isfoden har altsaa næppe nogen ødelæggende Virkning paa Algevegetationen, og forsaavidt er der altsaa ikke noget til Hinder for at bruge Tangranden til Bestemmelse af, om Landet hæver eller sænker sig, saaledes som af Dr. Steen- strup foreslaaet. Foruden lagttagelser over Isfodens Dannelse studerede jeg de grønlandske Stednavnes Etymologi samt foretog meteoro- logiske Observationer samt Lysmaalinger ved Hjælp af Steen- strups Lysmaaler. Resultaterne findes meddelt her. Dato 8 2 8 Dato 8 2 | Oktbr Term: 1.5 2.9 1140) Oktbr. 2.0 Max ere 3.0 årg IH In ie ae: oe --3.5 | .. 9. 4! Vindstyrke ..

Ved Siden af disse Lysmaalinger foretog jeg ogsaa nogle Lysmaalinger, hvor der over Skalaen var lagt et Gelatinestykke, uigennemtrengeligt for de violette Lysstraaler.

Forst i Begyndelsen af Januar sank Temperaturen saa meget, at Disko-Bugt i Vige og Bugter blev islagt; men dette Isleg var dog meget usikkert. Endelig den sidste Uge af Januar blev Islæget saa sammenhængende, at man kunde befare det med Hundeslæde. Den 31. Januar brød jeg op med Torsukatak som Maal. Vejen lagdes over Kekertak. Herfra korte jeg ind i det indre af Torsukatak, hvor jeg slog mig ned hos en Gronlænder, Vitus Petersen, i Anä. Jeg havde her god Lejlighed til paa nermere Hold at studere Gronlendernes daglige Liv om Vinteren. Her ved Anä boede kun to Familier. Min Vært var en udmærket Fanger, som ikke blot ernærede sin egen Familie, men tillige underholdt den anden; til Gengæld maatte denne gaa ham til Haande. Hans Kue (Spækhus) var altid stoppet med Kod og Spæk. Da jeg ankom, fodrede han mine Hunde med Selkod. Med en ikke uberettiget Stolthed kunde han sige: «Se, det kan jeg tillade mig; havde det været i Kolonien, saa var Gronlænderne kommet paa alle fire for at spise med». Overhovedet kan man vel vanskelig undgaa at legge Mærke til, at jo længere man kommer bort fra Civilisationen, repræsen- teret af Butik og Præster, desto dygtigere er Gronlenderne. 1 det indre af Fjorden er der forøvrigt en usædvanlig god Fangst paa Fjordsælen; men der er langt til nermeste Handelsplads. Foruden Fjordsælen er den spættede Sæl ret hyppig i Torsu- katak; den kommer derind i Juli Maaned for at kaste Unger. Som Vitus Petersen fortalte, holder den til ved Nuna- taken og ikke ved Kekertakasik, der findes altsaa nu «Kasigisat ernivisat» og ikke lenger ved Kekertakasik, hvor den i Steenstrups Tid plejede at yngle. Det Hus, jeg boede i, var af Middelstorrelse med folgende Dimensioner. Hojden var 2 m Dybden var 4.3 m, Læng- den 2.9 m. Gangen var over 4 m lang — alt indvendigt 208 Maal. — Huset var som andre ægte Gronlenderhuse opført af Græs- og Lyngtorv indvendigt beklædt med Brædder. Brik- sen fandtes langs Nordvæggen, Vinduet mod Syd (Fig. 9). Langs Ost- og Vestvæg fandtes Bænke, og i en Krog stod en Koge- kakkelovn. Som her fremstillet er de fleste Gronlenderhuse byggede; der kan selvfølgelig vere betydelig Forskel saavel i Udstyrelse som i Indretning. Er Husejeren fattig, mangler Gulvbrædderne, den bare Jord tjener da til Gulv; hyppig er Væggene heller ikke beklædte med Bræåder, saaledes at man ser den nøgne Tørvevæg. Kni- ber det haardt, findes der i Loftet ikke flere end de aller nødvendigste Brædder, for at Tørvene, der danner Taget, kan bæres. Er Husejeren meget fat- tig, mangler der naturligvis ogsaa Glas i Vinduet. I Stedet for Glas anvendes en tynd Hud, og om Vintéren tilstopper man helt Vinduet. Ogsaa i Indretningen af Vinduer og Husgang kan der, som berørt, være en Del For- Fig. 9. ; aie skelligheder i det enkelte. Men det er en fast Regel, at Vinduet vender mod Syd — naturligt nok. — Husgangen er ikke afhengig af nogen bestemt Verdens Retning, men det synes, som dens Beliggenhed er afhengig af Landingsstedet. I de fleste Tilfælde gaar Husgangen mod Kysten eller parallel med den. Doren sidder snart paa Siden af Husgangen, snart for Enden; men ved mindre Bopladser vender den altid ud til Landingsstedet. Om Husgangen lober mod Landingsstedet eller parallel med Kysten afhænger vistnok af Terrainforholdene. I Kolonierne og paa sterre Bopladser holder 209 denne Regel ikke Stik. Husene ligger her ofte langt borte fra Kysten, og andre Betingelser gor sig gældende. For en Europæer synes Husene at være smaa og ube- kvemme; i Virkeligheden er de udmerket tilpassede til den gronlandske Natur. Husets Opgave er her som alle Vegne at beskytte Beboerne mod Vejrligets ubehagelige Sider. Kulden er i Grønland den ubehageligste og mest paagaaende Faktor. Midlet derimod, Brendsel, er ikke til Stede i Rigdom, tvert imod. Kun paa enkelte Steder findes Kul. Ellers maa Gron- lænderen se sig om efter andet Brændsel. Spæk er ganske vist et godt Brændsel, men det er dyrt og i sløje Fangsttider — f. Eks. den første Del af Vinteren — næsten ukendt. I Uper- nivik-Distrikt, hvor det flere Steder er vanskeligt at faa Brænde, maa man ty til Spæklampen. I den mellemste Del af Grønland bruger man Hedekvas og Tørv, i den sydligste Del, hvor der paa gunstigere Lokaliteter findes lidt vantreven Birke- skov, træder rigtigt Brænde til. I det hele og store er Brænd- selen sparsom og Kulden stærk; det gælder derfor om at gøre det Rum, der skal opvarmes saa lille som muligt og tillige saa lunt som muligt. Om Natten kan der forøvrigt i en saadan Grønlænderhytte, naar dens Beboere optager næsten hver Tomme, blive saa lummervarmt, at det næsten er uudholdeligt ; for Ventilationen sørges der ved et Hul i Loftet, der ellers er tilstoppet af en Græstot. Mod Regn er Grønlænderhuset daar- ligere tilpasset. Imidlertid er Regnen jo forholdsvis sparsom og falder kun om Sommeren, paa en Tid hvor- Husene ofte er forladte, og Grønlænderne bor i Telt paa Sommertangstpladserne. Naar det om Sommeren falder ind med en længere Regn- periode eller med voldsommere Regnskyl, gaar Vandet gennem de flade Tage. Ved at lave Tagene skraa vilde Grønlænderne undgaa denne Ubehagelighed, men til Gengæld blev der højere Ш Loftet, hvorved der udkrævedes mere Brændsel. Af to Onder foretrækker Grønlænderne det mindste. Storm og Sne 210 kan ikke gore de lave, tætte Huse nogen Fortræd; Sneen bi- drager forovrigt yderligere til at isolere Huset. Efter de Erfaringer, jeg havde gjort iTasiussak, mente jeg, at en Lodline paa 500 m vilde være tilstrekkelig til at maale Dybderne i Torsukatak. Det viste sig imidlertid, at det ikke var tilstrekkeligt, naar jeg kom ud til de midterste Partier af Fjorden. Fra Kekertak fik jeg en ny Line. Resultatet af Lodskuddene findes aflagt paa Kortet. Som man vil se, har jeg ikke kunnet meddele Lodskud for den inderste Del af Fjorden nærmest Indlandsisen. Isen var her saa fuld af Kalvis og saa sammenskruet, at det næsten var umuligt at komme frem. Tillige var det en ret farlig Sag at komme her, fordi Isflager som Folge af Isstrommens Bevægelse ofte skrues lod- ret i Vejret. Uagtet vi endnu kun var i den forste Uge af Februar, kunde man dog godt staa op allerede Kl. 6; inden man ВК alting klaret, var der allerede saa megen Lysning, at man kunde se at færdes paa Fjorden. Ofte maatte man tilbage- legge et godt Stykke Vej, inden man naaede Arbejdspladsen. Vejret var forøvrigt meget smukt; en Fohn havde afsmeltet det meste Sne, saaledes at det ganske saa ud som Foraar — sordlo upernak — som en af Gronlænderne sagde. Den nordlige Gletscherarm ligger ugunstigt, naar det gælder om at komme paa det rene med Kalvningen, fordi man ikke fra Panekarajok kan komme til at iagttage Gletscher- enden en profil; men for enkelte Partiers Vedkommende kan der ikke vere Tvivl om, at de stiller sig med fremadheldende Rande. Nogen Kalvning havde jeg ikke Lejlighed til at iagttage. Saavel Helland som Steenstrup har foretaget Hastig- hedsmaalinger fra Panekarajok. De af dem benyttede Basis- punkter kunde jeg ikke finde, være sig enten fordi de Varder, de har opstillet i Endepunkterne af Basis, er faldet ned, eller fordi de overhovedet ikke har ofret nogen Tid paa Opforelse af Varder. Paa Tilbagevejen over Panekarajok traf vi en 211 Flok Rensdyr paa 6 Stykker; efter Gronlendernes Udsagn be- gynder forevrigt Rensdyrene ogsaa at blive sjældne i disse Egne. Det lykkedes Gronlænderne at nedlegge et Dyr, men det tog ganske vist saa megen Tid, at det var fuldstendig merkt, inden vi naaede Strandbredden; yderligere maatte vi vente to Timer, førend vi kunde komme ned paa Isen, da det netop var Ebbe, da vi naaede Strandbredden. Den sydlige Arm af Gletscheren frembyder forsaavidt bedre Vilkaar for lagttagelse af Kalvning, som man her fra en Klippe- ryg har udmerket Udsigt over Gletscherenden, i hvert Fald et storre Parti af den. Her staar Gletscheren med fuldstændig lod- rette Vegge, maaske snarere en lille Smule tilbageheldende paa enkelte Steder. Desværre fandt der ingen sterre Kalvning Sted under mit Ophold ved Gletscheren; kun rutchede der paa et Sted et Parti ned; efter denne Kalvning stod Randen meget sterkt tilbagelenet. De Steder, hvor, som omtalt, Randen staar lidt tilbagelenet, er formodentlig Steder, hvor der fornylig har fundet Kalvninger Sted. Nogle Dage senere opholdt jeg mig atter ved Gletscheren; der fandt en Kalvning Sted noget hef- tigere end den foregaaende Gang. Kalvningen bestod ogsaa denne Gang i en Nedstyrtning. Umiddelbart efter begyndte der en voldsom og vedholdende Kalvning af den nordligere Gletscher. Hvor sterk Isskruningen kan vere her inde i den indre Del af Fjorden, fik jeg Lejlighed til at iagttage paa Tilbagevejen. Vi fulgte naturligvis vort forste Spor, men paa en Strekning af over 30 m forsvandt Sporet aldeles; paa en lodretstillet Is- flage saa jeg nogle af dem. Hele Bredden var paa et Sted, hvor den skraanede jævnt ned mod Havet, fuldstændig barika- deret med Isblokke og Flager, der var skruet ind over Bredden. Efter Granlændernes Udsagn kan der hen paa Foraaret paa den Maade dannes en Vold paa c. 10 m’s Hojde eller mere. Baade paa den nordlige og sydlige Side af Fjorden findes der Husruiner i det indre af Fjorden. Disse Omstendigheder foranledigede min gronlandske Ledsager til at fortelle, at i tid- 212 ligere Tid havde Forholdene været helt anderledes; man havde endog sejlet om Anå. Intet tyder paa, at dette er rigtigt. Husresterne herinde stammer fra den mere oprindelige Tid, da Grønlænderne boede mere spredt og ikke blev tiltrukket af de danske Handelspladser; thi Forbindelsen med Omverdenen er naturligvis meget vanskelig en stor Del af Aaret; bedst er den om Vinteren. Som Kortet viser, er det ret betydelige Dybder, der træffes i det indre af Fjorden, 720 m. Der kan næppe være Tvivl om, at. den store Dybde er tilvejebragt af Gletscheren, der i sin Tid skød sig ud gennem Fjorden. Alle Sidegrene til Fjorden: Kangerdluk og Ikarasak er ikke videre dybe — efter de faa Lodskud at dømme. Der har ingen eroderende Virksom- hed været, snarere er der blevet aflejret Morænemateriale. For- øvrigt er det kun et beskedent Antal Lodskud, der staar til Raadighed, vedrørende de grønlandske Fjordes Dybder. Dr. Steenstrup har foretaget nogle Lodninger ved Umanak, hvor Dybderne viser sig at være ringere end i Torsukatak. Hammer har foretaget nogle Lodninger i Jakobshavns-Is- fjord syd for Kingigtok, men for nær Land og i for ringe Antal til at de kan give nogen Oplysning om Dybdeforholdene i Jakobshavns-Isfjord. Jensen har foretaget Profil- lodninger i sydgrønlandske Fjorde. Det havde været min Hen- sigt at foretage nogle Lodninger i Ikarasak og derefter i det store Basin syd for Ana og. Kekertakasik. Rimeligvis er den nordlige Del temmelig lavvandet, fordi den er opfyldt af Materiale fra Torsukatak-Gletscher. Derimod vil det for- modentlig nok vise sig, at der i den sydlige Del kan paa- vises en Rende, der er dannet af Gletscherne, der har skudt sig videre frem gennem Ata-Sund. Ikarasak kunde imid- lertid ikke befares. Isen er her paa Grund af den stærke Strøm — der jo netop tyder paa, at Strædet er lavvandet — usikker og stedvis fuld af Vaager. De faa Lodskud i Begyn- delsen af Ikarasak tyder ogsaa paa, at Farvandet ikke er dybt. 213 Efter at have fremskaffet en Del Oplysninger om Dybde- forholdene i det Indre af Torsukatak flyttede jeg sidst i Fe- bruar længere ud og slog mig ned i Nugak; ogsaa her boede jeg hos en Gronlender, der var Stedets Skolelærer, hvorved jeg fik et godt Indblik i den Undervisning, som den opvoksende Slegt i Granland faar. Med Hensyn til Lodningerne er der at bemerke, at jeg udforte dem med en temmelig tynd Line, 3-lebet Bindegarn. Dette havde den Fordel, at_jeg kunde anvende et temmeligt lille Lod, mellem 3—5 kg. Trods den ringe Tyngde kunde man dog med Lethed merke, naar Loddet stedte mod Bund. Uagtet Snoren var tynd og Loddet let, var det dog ret be- sværligt at trekke Loddet op. Jeg forsogte forst at benytte en Valse, men Linen frøs sammen, og at afvikle den var der- ved umuligt. Valsen var forevrigt den samme, som den Dr. Steenstrup benyttede 1879. At trække Loddet op med Hænderne fra en Dybde af 700m var baade langsomt og tret- tende. Derimod gik det meget nemt, naar man benyttede Hundeslede. Naar Loddet skulde hives op, blev Linen bundet til Hundesleden, hvorpaa man tog Retning mod det neste Lodsted. Paa den Maade gik Ophivningen baade hurtigt og let. For at Snoren ikke skulde skære sig ind i Isen, blev Skaftet af Token lagt over Hullet. Trods det lille Lod brast Linen dog ret jævnlig under Ophivningen paa Grund af Frik- tionen med Vandet. Naar Loddet kom op, tog Gronlænderen dette og vandrede hen til næste Lodsted. Medens Gronlen- deren huggede Hul i Isen, bestemte jeg Stedet ved Hjælp af et Pejlkompas. Paa den Maade var man i Stand til at ud- føre et i Forhold til Dybderne ret anseligt Antal Maalinger. Da Linen var temmelig tynd, var det nødvendigt ved Efter- maaling at korrigere for Strækning. Denne Eftermaaling blev udført med et Staalmaalebaand. Der er altsaa næppe større Fejl paa Lodskuddene; men forøvrigt spiller det ikke nogen nævneværdig Rolle, om der paa en Dybde af 700 m virkelig 214 skulde være en Fejl paa 2—3 Meter. Linen var inddelt i Læng- der paa 25 m. Det forste Mærke var 1 Knude, det neste 2 o.s.v. Hundrederne var ligeledes mærket med tilheftede Knu- der. Det var derfor let at foretage Aflæsningen. Til Bestemmelse af Lodstedets Beliggenhed benyttede jeg Tilbageskering. Forst benyttede jeg et Universalinstrument, men da det var sent at manøvrere med, og da man i 30° Kulde ikke kan holde ud ret lenge at staa med bare Hender og stille / 1 paa Stilleskruer, foretrak jeg et Pejlkompas, der var hurtigere Fig. 10. at arbejde med. Til Sigtepunkter ved Tilbageskering anvendte jeg Toppe og Pynter. Toppe giver en nojagtigere Bestemmelse end Pynter (se Fig. 10). Resultatet af Maalingerne i de ydre Dele af Torsukatak var, at Dybderne var omtrent som i de indre Dele. Kun lengst ude syd for Ekogfat blev Dybderne mindre; man kommer uvilkaarlig til at tenke paa en Isfjeldsbanke som ved Jakobs- havns-Isfjord, hvor der er mindre dybt end inde i Fjorden. 215 Det maa der nemlig vere; thi Isfjeldene driver uhindret ud gennem Fjorden, men tager Grund ved Mundingen. Banken er vel opstaaet som en Endemorene, da Jakobshavns-Glet- scher naaede helt ud til Mundingen; paa samme Maade er det rimeligt, at der uden for Torsukatak-Fjord maa ligge en lignende Endemorene, over hvilken Vandet er mindre dybt end inde i Fjorden. Forholdene minder altsaa meget om Ban- kerne langs Syd-Grenland, hvor der ligeledes findes dybere Vand indenfor. Bankerne er vel derfor i det store, hvad Jakobshavns Banke og Banken uden for Torsukatak er i det smaa. Ligesom Jakobshavns og Torsukataks Banke er opstaaet, da Isen havde en videre Udstrekning end nu og naaede helt ud til Mundingen af Fjorden, saaledes er for- modentlig de store Banker opstaaet, da Indlandsisen som en sammenhængende Kappe sked sig ud over Grenland. Disko- Bugt har den Gang veret helt udfyldt af Is paa samme Maade som de danske Farvande. Over Dybdeforholdene i Disko-Bugt har vi næsten ingen Oplysninger. I den mid- terste Del er der kun to Lodskud, der giver Dybder раа 400 т, altsaa meget beskedne Dybder i Forhold til Dybderne inde i Fjordene. Uden for Disko-Bugt er der et større Antal Lod- skud. Efter disse ser det ud, som om Isen er gaaet ud over «Rotten» i sydvestlig Retning. Nogen Is ег vel ogsaa gaaet ud gennem Vaigat; i dettes Munding findes der et Lod- skud paa 365 m, medens Dybderne uden for er mere beskedne, 90 m eller saa. Desværre findes der ikke noget Lodskud i den mellemste og sydlige Del af Vaigat og heller ikke i de tilgrænsende Dele af Disko-Bugt. Ellers vilde man maaske kunne udlede, hvilken Vej Torsukatak-Gletscher har taget. Vi var nu naaet til Midten af Marts, og Islæget var vel nu paa det bedste. Jeg besluttede derfor at bryde op og køre syd paa for at naa over Jakobshavns-Isfjord, der som be- kendt, som Følge af den stærke Strøm fremkaldt af Tidevandet, ofte er fuld af Vaager og Strømsteder i Mundingen. Paa Vejen 216 syd paa gjorde jeg holdt i Ata 9: det Land, der ligger under; et Navn, der er meget treffende, fordi Ata netop er et lavt- liggende Forland, ovenover hvilket selve Agdlutok hever sig til 400 m. Denne Forskel paa Atä og Hovedlandet skyldes sikkert en Forkastning, der lober i nordostlig Retning, markeret af Søen Taserssuak og Bugten Kangerdluatsiak ved Torsukatak. Selve Bopladsen Ata er lille; der findes ialt kun fire Huse. Beliggenheden er ogsaa daarlig, man vil nesten — med gron- landske Erhvervsforhold for Oje — sige naturstridig, idet den nemlig ligger i en Bugt. Fangsten er kun ringe; om Foraaret er der dog nogen Utôk-Fangst. Aarsagen til, at Bopladsen der er kommet til at ligge der, maa vel soges i, at For- bindelsen med Omgivelserne er forholdsvis let, saaledes over Taserssuak til Arsivik og videre over Torsukatak til Nugak og over Agdlutok til Ritenbenk. Medens jeg var ved Ata, benyttede jeg Lejligheden til at foretage nogle Lod- ninger i Atä-Sund ([karasak). Med Torsukatak in mente kunde man vente, at man ogsaa i Atä-Sund vilde træffe store Dybder, dels er det jo temmelig bredt, dels er det omgivet af hojt Land, der falder brat ned. Saaledes var det dog ikke; Ata-Sund er i sin nordligere Del ikke dybere end 300 т. Denne Dybde finder man temmelig almindelig. Ogsaa paa Søen bag Ata, Taserssuak, foretog jeg en Lodning. Det var dog meget besverligt, da Isen var godt og vel en Meter tyk; Dybden af Søen var næsten 100 m, en ret betydelig Dybde i en Ferskvandsso. I forste Række skyldes Dybden vel Forkastningen; men Isen har sikkert ogsaa veret medvirkende, idet Gletscheren, da Isens Megtighed var storre, er stemmet op af Agdlutok hoje Land og har beveget sig ned langs dette og videre ud gennem Ata-Sund. Da det tog en uforholdsmessig lang Tid at faa hugget Hul i Isen, foretog jeg kun denne.ene Maaling i Taserssuak. 217 Derefter korte vi videre syd paa gennem Ata-Sund og over den smalle Tange ved Kitsermiut til Pakitok, hvor vi boede i et lille Hus, opført til Brug for de postrejsende. Fra Niakornak kom der Gronlendere paa Besog. De oplyste os om, at Trafiken over Jakobshavns Istjord havde veret meget vanskelig i Aar; kun ganske faa Sleder var sluppet over. For Ojeblikket var den ganske ufarbar. Jeg besluttede mig derfor til at blive ved Pakitok en Uges Tid eller saa. For at komme ind i det indre af Fjorden (Pakitup Illua) maa man over en smal Landtunge, fordi der i den snevre Munding er en meget sterk Strom, der forhindrer Is- leget. Illua er, som alle Soer i det lave Land, dekket af store Mengder Sne, som gor Korselen meget besverlig, fordi Sleden skærer sig helt ned i Sneen. Denne Fjord bliver kun forholds- vis sjeldent besegt og har derfor ogsaa kun faa Stednavne. Kun nogle Øer og Forbjerge har Navn. Min grønlandske Led- sager var dog godt kendt her; han var fodt i Pakitok og havde boet der en lengere Rekke Aar, men var for faa Aar tilbage flyttet Ш Ata. Pakitok ligger ikke godt for at vere en god Fangstplads; den ligger nemlig paa en Maade i en Bugt. Ganske vist ligger der et storre Farvand, Illua, bag ved. For saa vidt kunde man tro, at Beliggenheden ikke var saa daarlig. En Beliggenhed ved et Overgangssted mellem to Havarme er netop en ikke ualmindelig Beliggenhed af Boplad- ser i Gronland. Men Illua har ikke ret meget at byde paa; ganske vist findes der mange Ænder; men disse er de sidste Aar aftaget sterkt i Mengde. Det store Antal Edderfugle be- ror paa, at Illua, — som vi skal se, — er temmelig flad. I tidligere Aar var ogsaa den spraglede Sel almindelig i Yngle- tiden. Saalenge Illua altsaa havde noget at byde paa, var det naturligt nok, at der her ved Pakitok blev lagt en Bo- plads. Stedet laa paa en Maade centralt, man kunde let komme mod Øst, der bød paa Edderfugle og spraglede Sæler, og mod Vest til Ikarasak (Atå-Sund) og Disko-Bugt, 218 hvor Fjordsælen holdt til. Desuden er der umiddelbart ved Bopladsen et udmærket Torskefiskeri; — paa en god Time fangede min Ledsager 56 Torsk. Da nu Edderfuglen blev mere og mere sjælden, og den spraglede Sel ligeledes, har Fangsten mod Ost ingen Betydning mere, og Stedet kommer derfor erhvervsmæssig set til at ligge inde i en Bugt. Derfor er Be- boerne rykket mod Vest ud til Niakornak, nogle er draget til Ata; der findes nemlig en Butik; men ellers er Atas Beliggenhed jo ikke gunstig. Selve Bopladsen ved Niakornak hedder forovrigt Kilersiut (Haartoppen), fordi man aabenbart har sammenlignet Halvoen med en Haartop, som er indsneret paa Midten. Over denne Indsnoring gaar Sledevejen til Ja- kobshavn. Bopladsen er forevrigt kun beskeden, idet der kun findes fire smaa Huse. Der kommer for faa Isfjælde herop, til at der kan vere mange Sælhunde. Der fanges Hajer, lidt Kaleralik og Torsk. Omkring Niakornak er der paa Grund af Tidevandet temmelig stærk Strom, og det synes, som om Torsken gerne holder til, hvor der er Strem. Det er vel derfor, at der netop ved Pakitok findes saa mange Torsk. Pakitok afgiver et godt Eksempel paa, hvorledes en Bo- plads’ Beliggenhed afhænger af Oplandet 9: dens Neringsgebet. Saa vidt muligt søger en Boplads ikke blot i Grønland, men ogsaa alle andre Steder, at legge sig saa centralt som muligt i Næringsgebetet, og det gælder aabenbart lige saa godt om store som om smaa Bopladser; kun bliver Forholdene for de sterre Bopladser mere indviklede. Naar de ostjyske Kobsteder ligger helt inde i Bugterne, spiller sikkert denne Beliggenhed en bestemt Rolle lige overfor Byernes Opland; netop ved at liege inde i det Inderste af Fjorden opnaar de at faa det størst mulige Opland i Forbindelse med Adgang til Havet. Ser man paa et Kort over Gronland i en nogenlunde stor Maalestok, f. Eks. de fortrinlige Kort, der udgives af Sokortarkivet, kan man ikke undgaa at legge Merke til, at de gronlandske Bo- pladser, sterre og mindre, fortrinsvis ligger paa Spidsen af 249 Halveer og Øer, ikke just saaledes at forstaa, at Bopladsen ligger paa den geometriske Spids, det gør den i mange Til- feide ikke — af Grunde, som vi senere skal omtale — men dog i umiddelbar Nerhed deraf. En Beliggenhed paa Spidsen af en Halvo eller @ frembyder de bedste Betingelser for Fang- sten. Fangerens Domicil skydes jo paa den Maade ligesom ud i Fangstomraadet. Boede han nede paa Siden af en Halvo, havde han kun en Halveirkel at jage i, nu derimod faar han det meste af en Cirkel. Kan han ikke sætte Kajaken i Vandet paa Grund af Bolgeslag fra den ene Side af Halvoen, saa kan han uden stor Ulejlighed gore det fra den anden. Overhovedet har Fangeren Mulighed for at kunne vende sig til to Sider, alt efter Forholdene. Ved at bo paa en lige Kyst maa han altid vende sig til en og samme Side. Som berort spiller Landings- forholdene — Havneforholdene for de storre Bopladser, Byer — en vigtig Rolle, netop fordi Eskimoen i saa hoj en Grad er henvist til at soge sit Erhverv paa Seen. Af den Grund kommer Bopladserne ikke netop til at ligge paa selve Spidsen; denne er maaske stejl, et Stykke derfra er der maaske en bedre Landingsplads, følgelig kommer Bopladsen til at ligge der og ikke paa den geometriske Spids. Paa et Kort i middelstor Maalestok f. Eks. Sokortene projiceres dog Bopladsen som liggende paa Spidsen — man kunde nesten kalde det den geografiske Spids — Maalestokken tillader ikke nogen Afvigelse. Selvfolgelig gives der Undtagelser — endda mange Undtagelser fra denne Regel. Disse vil vel meget ofte vise sig at ligge i, at der paa Spidsen og dens nermeste Omegn er daarlige Lan- dingssteder, maaske mangler ogsaa Drikkevand. Inde i Bugter er det i hvert Fald ikke almindeligt at treffe Bopladser, med mindre der er et nemt Overgangssted til et andet og godt Jagtomraade. 1 Fjorde, i hvilke der gaar Gletschere ned, og hvor der dannes rigeligt med Isfjælde, kan man dog treffe Bo- pladser, saaledes inde i Torsukatak. Men ogsaa her er der en Tilbojelighed til at legge Bopladsen paa еп Pynt; Ana og XXXIV. 15 220 Nugak er Eksempler herpaa, ligeledes Husruinerne paa den nordlige og sydlige Side af Torsukatak. For de Bopladsers Vedkommende, der ikke ligger paa Pyn- ter eller i umiddelbar Nærhed deraf, maa man ikke lade sig forlede til at tro, at de har en tilfældig eller endog unaturlig Beliggenhed. Som Eksempel kan jeg nævne Klavshavn; man skulde tro, at Eke, naar man blot ser paa Kortet, har en naturligere 9. bedre Beliggenhed, og dog findes der kun tre Huse, medens Klavshavn jo er en efter gronlandske Forhold stor Boplads. Tilsyneladende er Eke beliggende paa en Spids. Det er dog ikke ganske rigtigt, naar man tager andre Forhold med end de rent kartografiske. For det forste er Isfjorden for det meste saa pakket med Is, at den er ganske ufarbar, og dernest ligger der en megtig Isfjeldsbanke uden for Mundingen. Erhvervsmæssigt set ligger Eke snarere i en Bugt end paa en Pynt. Karakteristisk nok betyder Eke netop Vig, Bugt. I Virkelig- heden ligger Klavshavn gunstigere, herfra kan Fangerne dels nyde godt af Isfjældenes Nerhed, dels har de Tasiussak i Ryggen. Tasiussak spiller for Klavshavn en vigtig Rolle: om Sommeren er der et rigt Fugleliv og noget Laksefiskeri, om Vinteren er der godt Kaleralikfiskeri og lidt Selhundefangst. Paa samme Maade vil man formodentlig ogsaa for de andre Bopladser, der ikke ligger paa Pynter, kunne gere Rede for Aarsagen til, at de ligger netop paa det Sted. Saaledes er det let at klarlegge Forholdet mellem Kingigtok og Jakobs- havn, der i alt væsentligt forholder sig som Eke og Klavs- havn. Hvad den sidste har i Tasiussak, har Jakobshavn i sin Havn, der har gjort Bopladsen til en Koloni med de deraf flydende Fordele. Overhovedet indtager Kolonier og Handelspladser en særlig Stilling; her er det saa at sige udelukkende Havneforholdene, der er det afgørende, medens Fangstforholdene ikke ved Valget har den afgørende Betydning. Som Følge deraf ligger et stort Antal Kolonier og Handels- 221 pladser slet ikke paa Pynter, hvor der jo sjælden vil være gode Havne. Men Handelen med Danmark er jo ikke nogen oprin- delig eskimoisk Erhvervsgren, selv om‘ den i vore Dage over stor Indflydelse. Som hos alle primitive Folk, der lever af Jagt og Fiskeri, er Opholdsstedet ikke af stor Varighed. Naar Fangsten af en eller anden Grund ikke mere giver tilstrækkeligt af sig et Sted, vandre Beboerne til andre og, som de haaber, bedre Fangst- pladser. 1 tidligere Tid har saadanne Vandringer ret ofte fundet Sted (sé Holms Konebaadsekspedition). Man finder i det indre af Fjordene Ruiner nesten alle Vegne, hvor Forholdene har veret egnede til Boplads. Opforelsen af Husene danner ingen større Vanskeligheder eller Udgifter; den Smule Tommer, der fandtes i det forladte Hus, kan jo fores med og benyttes paa ny. Nu er Beboerne vistnok mere stavnsbundne, og helst vil de bo et Sted, hvor der ikke er for langt til Butiken. Da Handelspladserne ligger ved Kysten, har Gronlenderne mere og mere klumpet sig sammen der, hvilket er naturstridigt. Et Jagt- og Fiskerfolk skal ligesom Rovdyr bo saa spredt som muligt, derved bliver der det størst mulige Jagtomraade til hvert Individ. Foruden i det nævnte Hus ved Pakitok boede jeg i Telt inde ved Indlandsisen og ude ved Atå-Sund. Indretningen af et Vintertelt er ganske simpel. Af to almindelige Sommertelte, saaledes som de bruges paa de af Kommissionen udsendte Ekspeditioner, havde jeg gjort det ene en Smule mindre. Paa de Teltstænger, der bar det ydre Telt, havde jeg anbragt to Klodser, paa hvilke den Rygstang hvilede, der bar det indre Telt. Ved Snore var der sørget for, at det indre Telt holdtes i en Afstand af omtrent et Kvarter fra det ydre. Naar Primus- apparatet var tændt, kunde der blive saa varmt, at man kunde sidde uden Overtøj; oppe under Teltryggen var der helt varmt, hvilket var godt til Tørring af Kamiker. Om Natten kneb det mere; da gik Primusapparatet ud af Mangel paa Pumpning. 15° 222 Havde man haft et lille Dowlastelt, der kunde have hvilet paa en Snor, udspændt mellem Teltstængerne, saaledes at man altsaa havde lavet sig et tredobbelt Telt, havde det sikkert veret behageligere. Hvad et saadant Dobbelttelt vejede ved jeg ikke. Men foruden Teltet kunde jeg have to tætpakkede Kasser paa Sleden, i hvert Fald paa Isen, paa Land, navnlig i couperet Terrain, kunde Hundene vanskelig trekke saa meget. I Avanardlek-Dal fandt jeg omtrent midt i Dalen to Gletscherskrammer, som krydsedes. Den ene løb i Dalretnin- gen, NÖ-SV, den anden i Ost-Vest. Hvilken af de to Skram- mer, der var ældst, kunde ikke ved blot og bar lagttagelse af- gores, saa ens var de. Men man maa vel antage, at Skrammen, der havde Retningen Ost-Vest, var den ældste, dannet i den Tid, da Indlandsisens Megtighed var saa stor, at den upaa- virket af det underliggende Terrain bevegede sig ud over Yder- landet i vestlig Retning. Den anden Skramme i Nordest-Syd- vest henpeger paa den Tid, da Indlandsisen vel havde en sterre Megtighed end nu, men dog i Hovedsagen maatte folge Ujevn- hederne i Terrainet. Tidsrummet, som ligger mellem Frem- bringelsen af disse to Skrammer, maa vere ret betydelig, og Ismassen, som har beveget sig over Stedet i Mellemtiden, maa have veret stor. Og dog har disse Ismængder ikke formaaet at erodere saa meget i den faste Klippe, at den ældste Skramme er bleven slebet bort. Dette viser, hvor ubetydelig selve Isens eroderende Virkning er, naar den skal bearbejde en fuldstændig kompakt Klippe. Gletscheren, som skubber sig ned mod Avanardlek, har trukket sig kendeligt tilbage. Paa en Strækning af en km kunde man paavise, at Klipperne i Nerheden af Gletscheren kun var sparsomt eller endog slet ikke bevoksede med Likener. Langs Siderne laa en stor Endemorene; for Enden af Glet- scheren manglede en saadan. Smeltevandet havde dannet en megtig, ganske flad Flodseng. I denne Dal fandt jeg de fra arktiske Lande kendte Hoje, der opstaar, ved at Grundvandet, 223 der ikke kan synke i Jorden, presser Isskorpen op næsten som et Krater. Nogle af disse Høje var store, 3 m eller mere i Diameter. Fra det hoje Land nord for Gletscheren har man en vid Udsigt mod Nord og Vest. I en Lavning ved det hoje Fjeldparti, hvor Indlandsisen sender en Tunge ind, rislede Vandet frem under Gletscheren for dog straks efter at fryse. Lufttemperaturen var — 26°. Ogsaa den sydlige Gletscher havde trukket sig tilbage. Dog var det vanskeligt nøjagtigt at bestemme, hvormeget Isen havde trukket sig tilbage, da nyfalden Sne udviskede Græn- serne. Saa vidt jeg kunde skønne, har vistnok Isen trukket sig omtrent 200 m tilbage. At Gletscheren maa være noget i Aftagen fremgaar ogsaa deraf, at en stejl Klippe rager frem midt i Gletscheren, og denne Klippe er lysgraalig og ikke sortegraa, saaledes som lichenbevoksede Klipper ellers er. Naar den ikke er lichenbevokset, kan det vel kun skyldes den Om- stændighed, at den tidligere har været dækket af Isen, men nu er bleven fri. I Gletscherens Sidepartier havde jeg Lejlighed til at iagt- tage Gletscherkornene uden at behøve i Forvejen at farve med Methylenblaat; slamholdigt Vand var i Sommerens Løb sivet ind mellem Kornene og dannede nu et fint spindelvævsagtigt Net. Man kunde derfor meget let se Kornenes Form og Størrelse. Kornene var alle smaa, omkring 2 cm. Overhovedet har alle de Gletscherkorn, jeg har haft Lejlighed til at iagttage påa de forskellige Steder, altid været temmelig smaa. Fra Bjergene syd for Kujadlek har man en god Udsigt endogsaa helt ind i Tasiussak, naar det var klart Vejr. Paa Illua foretog jeg nogle Dybdemaalinger. Mærkelig nok viste Lodskuddene over en større Strækning i den cen- trale Del samme Dybde, nemlig 325 m, en Dybde, der ganske vist i Forhold til Dybderne i Torsukatak er beskeden, men naar man tager Hensyn til, at Illua er et lukket Farvand, der ikke en Gang naas af Gletscherne mere, er det dog en anselig 224 Dybde. Lodningerne var sene at udfore, da Isen var 0,8 m tyk. Indad mod de to Sidefjorde tager Dybden af; den sydlige af disse er endog saa flad, at man ikke kan befare den med Konebaad. Illua er fuld af Smaager; om det er selve Klippe- grunden, eller det er Gletschermateriale, aflejret, da Gletscheren skød sig ud gennem Illua, ВК jeg ikke undersøgt. Efter selv at have veret i Jakobshavn for at forhore mig om Mulighed for at slippe over Jakobshavns-Isfjord, foretog jeg позе Lodninger i den ydre Fjord, hvor Dybderne er omtrent som i den indre Fjord, dog gennemgaaende noget mindre. Vejret var stadigt meget uroligt, snart Taage, snart Storm. Temperaturen var i nogle Dage relativ høj, — 12°. Da det viste sig at være umuligt at slippe over Jakobs- havns-Isfjord, vendte jeg mig atter mod Nord, idet jeg først slog Telt ved Kitsermiut for at foretage nogle Lod- ninger i den ydre Del af Atå-Sund; Dybden mellem Nug- dluk og Kitsermiut var næsten 500 m (495 m). Ejendomme- ligt er det forøvrigt, at Dybderne over forholdsvis store Stræk- ninger er saa ens. Ikke mindre end 5 Lodskud gav samme Resultat nemlig 495m. Inde i Pakitup-Illua gav 3 Lodskud, der dog laa et godt Stykke fra hinanden, samme Resultat, nemlig 325 m. I Atå-Sund uden for Kaerssorssuak viste 3 Lodskud samme Dybde, 415 m. I Farvandet nord for Okaitunguit er Dybden over en stor Strækning 375 m. Noget lignende viste sig i Torsukatak. Man kan vanskelig antage, at Gletscherne skulde kunne erodere Klippegrunden saa mærkværdig jævn. Man føres snarere til den Antagelse, at den eroderede Klippebund atter, da Isen trak sig tilbage, er blevet udforet med Gletschermateriale; hvis dette er aflejret under Vand, er det let forklarligt, at Smeltevandet vil brede det jævnt ud. Fra Kitsermiut drog jeg til Kaersorssuak, hvor jeg døjede en Del af Kulden, trods vi nu var midt i April, og der- fra til Atå efter først at have taget nogle Lodskud i Atå- 225 Sund og været inde i Kangerdluarsuk og oppe paa Kaer- sorssuak Plateauet. Der ligger her flere store Soer paa Plateauerne. Den sidste Uge af April begyndte Vejret at blive mildere, og de sidste Dage i April saa jeg den forste Flok Snespurve; Foraaret var altsaa ved at indfinde sig. Paa en Udflugt til Natdluarssuk saa jeg Sporene af en Isbjorn; den havde aabenbart gjort en heldig Fangst; thi et Stykke derfra saa vi ved en Vaage Baglallen af en Selhund. Da vi senere steg op ad Nuna-Kigdliga, saa vi Sporene af en voksen Isbjørn og af en Unge. Om Natten havde den aflagt Besøg ved Teltet, men om Morgenen var den borte; Sporene tabte sig i en Vaage. En Uges Tid senere blev der i Tasi- ussak set to Isbjørne, men da Fangerne i Klavshavn ikke er Isbjørnejægere, drog hele Flokken ud, hvorved Bjørnene naturligvis blev yderst forskrækkede og forsvandt. Det er for- øvrigt meget sjældent, at Isbjørnen forvilder sig ind i Disko- Bugt. Da Afsmeltningen jo om Vinteren hører op, og Ablationen udelukkende bestaar i Fordampning, breder Gletscheren sig. Figur 11 forestiller et Tværsnit af Kanten af Ekip-Sermia. Gletscheren hænger som en Flage ud over Morænevoldens Ryg. Paa Undersiden af Flagen sad der fastfrosset Bundmoræne af store Sten og alle Grader nedefter i Størrelse. Om Sommeren smelter der saa meget af, at Gletscheren staar lavere. Den forholdsvis høje Temperatur de sidste Dage havde bevirket, at Isen var mindre sikker. Ved alle Pynter traf man Strømsteder, hvor der enten var aabent Vand eller tynd Is. Det var derfor nødvendigt at sætte over Torsukatak en af de første Dage. Den 30. April brød jeg op fra Atå og kørte over Atå Taserssuà mod Nord, derpaa over en lille Tange, saa et Stykke over Kangerdlukasik og endelig over Land til Ulugsat. Sundet mellem Kekertakasik og Ulugsat var nu ganske aabent. Maager, Edderfugle (baade mollis og specta- 226 bilis) og Skarven tumlede sig i Vandet. Paa Land var Sneen mange Steder forsvundet; Transporten var derfor meget be- sverlig, navnlig i Kororssuak (den store Dal), hvor Vejen gaar meget stejlt op. Ved Ulugsat overnattede vi. Den neste Dag satte vi over Torsukatak, hvor Isen mange Steder var saa mor, at man kunde stikke Token lige igennem, og kom velbeholden til Itivdliarsuk, en ganske lav Tange mellem Torsukatak og Kekertap-Illua. Ved Itivdliarsuk findes Fig. 11. kun eet Hus. Gronlenderen, der er en Storfanger, har tillige et Hus ved Ekogfat. Om Vinteren bor han ved Itivdliars- suk, hvor han driver Utok- og Garnfangst inde i Fjorden. Han var nu i Ferd med at bryde op og drage til Ekogfat for at drive Fangst fra Kajak; ved Ekogfat var Vandet mod Vest allerede aabent. Vi slog Telt ved Kugsarnek. Kugsarnek- Dal løber næsten lige mod Nord. Langs denne kørte vi op, indtil vi kom til en lille So, Amalortok; derpaa drejede vi mod ®st og naaede ned til Taserssuak-Isortok, der er en meget lang So, der strekker sig helt fra «Major- 227 vejen» til Kangerdluk inde ved Gletscheren. Her slog vi Telt (et lille Rejsetelt). Derefter korte vi et Stykke op ad «Boyes Vej»; men vendte forovrigt snart om, da Vejret, der hidtil havde været mildt og smukt, antog en stormfuld Karakter. Som omtalt tidligere lægger der sig paa Soer, der er beskyt- tede af Fjelde, store Mængder Sne. Om Dagen, naar Solen skinner, tor det overste Lag op, og Slæden skærer derfor igennem, ligesom man ogsaa selv synker ned til midt paa Livet. Det er derfor bedre at færdes om Natten; da fryser der atter еп Skorpe paa Isen, saaledes at man kan kere og gaa uden stadig at synke i. Derfor korte vi om Natten. Selv KI. 12 var det nu saa lyst, at man ret tydeligt kunde skimte Fjældtoppene, der laa omkring os, og dog var vi forst lige i Begyndelsen af Maj. Det har ogsaa sin Fordel at hvile om Dagen, saa kan man bedre udholde Kulden i Teltet. Fra Boyes Vej kerte vi videre mod Øst et Stykke paa en Elv, hvor Elven danner Af- løbet for Isortok og derpaa til Niakornak, hvor vi slog Тен. Herfra kørte vi om ad Amalortokujok og tilbage. Naar Torsukatak om Foraaret ikke længere kan befares paa Grund af Stromsteder, anvender Grønlænderne fra Kekertak og Nugak Vejen over Isortok ind til Kangerdluk for at naa ind til det indre af Torsukatak, hvor der er rig Utok- fangst. Helland, som besogte Torsukatak 1875, gik ogsaa denne Vej. | Kugsarnek-Dal fandtes der usedvanlig mange Вурег. Nu i Begyndelsen af Maj var det deres Parringstid. Da Vejret slog om til et efter Aarstiden sterkt Tovejr, maatte jeg bryde op og kore til Kekertak for ikke at blive afskaaret. Imidlertid blev det atter Frostvejr, og jeg tog saa med en Gronlender til Nugssuak-Halvo for om muligt at faa et Overblik over Forholdene i det шаге af Halvøen. Vi korte den sædvanlige Vej ad «Majorvejen» op Ш Majorkar- suatsiak, hvilket Fjeld af de Danske kaldes Majoren — efter de to forste Stavelser; heraf har man saa atter dannet 228 Navnet paa Vejen, der forer lige forbi Fjeldet. Fra Major- karsuatsiak drejede vi om til Tasek-Ujordlek, hvor vi for- øvrigt traf en lille Skare Rensdyr. Sarkrap-Tasersua synes at vere en meget flad So. — Lodninger fik jeg ikke foretaget, da jeg ikke havde medtaget de nedvendige Dele; — overalt ser man flade Øer og Banker, der, saa vidt jeg paa Grund af den frosne Jord kunde afgore, bestaar af Grus, Sand og Ler. Maa- ske har det oprindelig veret en dyb So, der i Tidens Lob er blevet udfyldt af Gletschermateriale. Rundt om skyder der sig Gletschere ned mod Seen. Fra Ujordlek korte vi over dennes Sydspids tilbage til Majorvejen. De to store Søer, Isortok og Ujordlek er vel at be- tragte som Kloftdale. I det hele synes Nugssuak’s Tektonik at bero paa Klovningssystemer, der løber i Nordvest-Sydost. Den tidligere omtalte So, Taserssuak, ligger netop ogsaa i samme Retning. Nugssuak er vel en Horst, hvis Randpartier er sunkne. Ved Ujordlek er Forvitringen meget sterk; store Klipper ligger her nedstyrtede under de lodrette Klippevegge. Lagene (Skifringen) synes her at ligge nesten lodret. Paa Tilbagevejen var Isen paa Kekertap-Illua saa tynd, at man kun med stor Forsigtighed kunde befare den. Jeg tog derefter med Bagagen til Ekogfat, 19. Maj, og den folgende Dag sejlede jeg med Konebaad til Ritenbenk forbi Jakobs- havns og derfra til Klavshavn, paa hvilken Rejse jeg havde rig Lejlighed til at iagttage Isfodens Oplosningsproces. Is- dekket laa endnu paa Tasiussak; desverre var Isen saa mer, at man ikke kunde kore paa den. Det var derfor umu- ligt at komme ind til Jakobshavns Isstrom. Derimod gjorde jeg nogle Ekskursioner til Isfjorden; navnlig interesserede det mig, om der skulde kunne findes Isfjelde i oprindelig Stilling; det fandtes der imidlertid ikke. Overhovedet havde Isfjorden sit sedvanlige Udseende: tætpakket med Kalvis. Ved Indlobet 229 til Tasiussak var Farvandet aabent. Den stærke Strom, der fremkommer her. som Folge af Tidevandet, skærer op i Isen. De sidste Dage i Maj kunde man sige, at Sommeren var i Anmarch. Den 29. Maj fandt jeg den forste blomstrende Empetrum. Ogsaa Saxifraga oppositifolia stod med helt ud- sprungne Blomster. Salix glauca var i Knopbrud. Ælymus havde grønne Blade ved Grunden. Midt i Juni stod Loisleuria, Diapensia, Vaccimum uligi- nosum i Blomst paa gunstige Steder. Paa Nordsiden blom- strede Empetrum endnu ikke; paa enkelte gunstige Lokaliteter blomstrede Dryas, Cassiope, Papaver, Rhododendron. Under mit Ophold i Jakobshavn havde jeg Lejlighed til at iagttage en «Kanel» i Havnen: «Kanel» er et Udtryk, som de danske Funktionærer bruger om en voldsom Bølgebevægelse i Havnen, der opstaar pludseligt, men som ogsaa forsvinder lige saa hurtigt igen. Bølgegangen er ledsaget af en stærk Brusen i det inderste af Havnen. Denne Brusen er ikke andet end Vandets Udstrømning fra en smal Kløft, naar Bølgen trækker sig tilbage. Denne voldsomme Udstrømning har, som Hammer meddeler, foranlediget Grønlænderne til at tro, at Havnen er forbundet med det indre af Jakobshavns-Isfjord ved en underjordisk Gang. Det er dog ikke Tilfældet; den om- talte Kløft, som Danskerne kalder Zimmers Kløft, er en Fortsættelse af Havnen. Havnen ved Jakobshavn er vel at opfatte som et Brud, yderligere eroderet af Indlandsisen, da den bredte sig over Landet; dette Brud fortsættes altsaa af Zimmers Kløft. Ad den kører Slæderne om Vinteren til Natdluarsuk. Til Forklaring af Fænomenet siger Hammer (Meddel. om Grønland IV, p. 22): «Disse Fænomeners Forklaring er maaske nærmest den, at Bølgerne, som ved Kalvningen bliver dannet i Fjorden, bliver brudt mod Isbanken i Mundingen og kastet tilbage mod Land, hvorved Vandbølgen bliver opstemmet i den 230 snævre og lidet dybe Havn og foraarsager en pludselig Stig- ning i Vandstanden og en frem- og tilbagegaaende Bolgebeve- gelse. Denne Vandbevegelse kan dog ogsaa undertiden vere svag og er da maaske foraarsaget ved en Kalvning af et Is- fjeld i Fjorden eller paa Banken. Man kan da ved hine sterke Bevægelser i Vandet komme til Kendskab om, hvor hyppig Kalvningen af Gletscheren finder Sted». Som vi ser tilskriver altsaa Hammer Aarsagen til «Kanelen» Kalvninger enten af Gletscheren eller af Isfjælde i Fjorden eller paa Banken. At selv en beskeden Kalvning af et Isfjæld paa aaben Kyst kan fremkalde Bølger påa 2—3 m Højde, har jeg haft Lejlighed til at iagttage paa Agdlutoks Vestside. I Torsukatak-Is- fjord har jeg ligeledes set en Kalvning, der frembragte meget store Bølger. Naar et af de store Isfjælde, som staar paa Grund ved Mundingen af Jakobshavns-Isfjord, kalver eller endog fuldstændig brækker i Stykker, maa denne Proces fremkalde et enormt Oprør i Vandet. Mange af de store «Kaneler» i Jakobshavn og tillige de største har sikkert sit Udspring fra Isbjærgenes Forstyrrelser ved Fjordmun- dingen og ikke fra Gletscherens Kalvning. Dels ligger denne с. 30 km fra Jakobshavn, og tilmed er Dannelsen af de store Isfjælde, dem i naturlig Stilling, næppe videre vold- som; her sker jo hverken nogen Nedstyrtning eller Kent- ring og for Resten heller ikke nogen Opskyden, tvertimod foregaar Dannelsen meget langsomt. Den storste Bolgebe- vægelse jeg har set, hidrorte fra et Isfjæld, som kalvede og derpaa kæntrede. Nedstyrtninger og Kentringer finder selv- folgelig ofte Sted inde ved Gletscheren, men deres Virkning, en heftig Bolgebevægelse, vil blive meget svekket, inden den naar Jakobshavn, dels paa Grund af Afstanden, dels paa Grund af den tetpakkede Ismasse, hvorved megen Energi for- bruges til at overvinde Gnidningen mellem Isstykkerne. Jeg er derfor tilbøjelig til at antage, at «Kanelen» hidrører fra Kalv- ninger af Isfjelde, der ligger ner Jakobshavn, altsaa paa Is- 231 fjeldsbanken eller i umiddelbar Nærhed af denne. Det hænder selvfølgelig ikke saa sjeldent, at der ligger Isfjælde uden for Mun- dingen af Havnen. Naar et saadant Isfjeld kalver, vil der selv- følgelig opstaa en heftig Bolgebevegelse i Havnen, altsaa en «Kanel». Til Belysning af, hvor hyppig Gletscheren kalver, kan man ikke bruge «Kanelen», eftersom den opstaar uafhengig af Gletscherens Kalvninger. Ved Klavshavn er Lagbygningen meget regelmessig, idet de der stryge næsten vinkelret paa denne med et Fald mod Nord paa 30°. Parallel med Kysten lober der et System af Diaklaser. Kysten er altsaa en Brudkyst, opstaaet ved en Sænkuing af Disko-Bugt Omraadet. Et ВИК paa Kortet viser, at Kysten i store Hovedtræk lober omtrent i en lige Linje og danner en Vinkel paa 10° med Meredianen. De mindre Af- vigelser er vel opstaaet ved, at løsere og fastere Lag veksle, og at de losere er blevet eroderet af Isen. Andre Spaltesy- stemer spiller vel ogsaa en Rolle, f. Eks. netop ved Jakobs- havn, hvor Lagene stryge parallel med Kysten, medens den saakaldte Leverbugt, der ligger paa tvers af Havnen, altsaa i Strygningens Retning, snarere er opstaaet ved Forvitring af løsere Lag. I hvilken Grad Afvekslingen mellem blødere og haardere Lag spiller en Rolle for Udformningen af Detaljerne i Terrainet, ser man tydeligt ved Itivdlek, Overberingsstedet til Tasi- ussak. Naar Vestkysten раа Agdlutok (Arveprinsens-®) har et saa regelmæssigt Forleb, skyldes dette vistnok for en meget væsentlig Del den Omstændighed, at Lagene stryge parallelt med Kysten og med Fald mod denne. De Revner, der findes, har Jsen ikke kunnet udnytte, da Kysten her laa i Lesiden, den Gang Iskappen i sin Tid skod sig ud over Yderlandet. For ikke i lengere Tid at ligge uvirksom rejste jeg den 27. Maj mod Syd. Det var min Hensigt at naa ind i Sydost- Bugt til de Strekninger, der paa Hammers Kort er betegnet ved Ler, altsaa Strekningerne mellem Tasiussarssuak og Havet. Jeg haabede tillige at kunne komme ind i Orpigsok- 232 Fjord. Jeg kom ikke meget lengere end til Akugdlet; thi i den inderste Del af Sydost-Bugt laa der endnu Is. Jeg maatte derfor vende tilbage. Da jeg var kommen tilbage til Klavshavn den 5. Juni, fortalte Fangerne, at nu var Isen brudt op i Tasiussak. Neste Dag brød jeg op for at naa ind i Tasiussak. Den for Transporten saa vigtige Audtlarissa-Tasia var dog endnu tilfrossen, eller rettere belagt med Is; denne var saa mer, at man ikke kunde gaa paa den. Slog man paa den, gik den i Stykker og faldt hen i de bekendte Isprismer. Konebaaden maatte derfor bæres syd om Søen og syd om Keakusuk. Dette er imidlertid meget besverligere end den sædvanlige Transport, hvor man kan sejle over Autdlarissa-Tasia. Overberingen tog derfor to Dage. Den Landtange, der ligger mellem Enden af Tasiussak og Havet, er ganske flad og be- vokset med Hedeplanter; forøvrigt fuldt af smaa Vandpytter. Den bestaar paa Overfladen af Sand og Grus, Havbredden af ganske fint Sand, sammenbundet af lidt Ler. Mod Tasiussak var Materialet i det hele noget grovere. Landtangens Hojde ligger mellem 30—40 m; saavel mod Tasiussak som mod Havet ender den med stejle Brinker. Mod Tasiussak, hvor Materialet er mere gruset, mangler Forsteninger ganske eller nesten ganske. Saaledes har jeg i Klinten her kun fundet et Fragment af en Balanskal. Grusmasserne er dog svagt lagdelt og maa altsaa vere afsat i Vand. I Skrenterne ud mod Havet er Masserne ogsaa lagdelt og indeholder en Mengde subfossile Muslinger. Denne Forskel i Materialets Beskaffenhed ved Tasi- ussak og ved Havet kunde tyde paa, at det er afsat i strøm- mende Vand, der har beveget sig i Retningen fra Tasiussak mod Havet. Kaster man et Tilbageblik paa Dybdeforholdene i Tasiussak, kan man vel kun finde den Forklaring, at der en Gang har staaet en Gletscher i Tasiussak, og at Landet den Gang laa 30—40 m lavere end nu. Antager man dette, er de forhaandenverende Kendsgerninger ganske godt forstaalige. Man 233 kan vel altsaa bedst opfatte disse flade Strækninger som et Gletscherdelta, afsat i Havet; Smeltevandet har planeret og sor- teret Materialet; de større Partikler findes ved Tasiussak, de finere er fort lengere bort. Mod Tasiussak, hvor Vandet var fersk, findes ingen Forsteninger, mod Havet, hvor Vandet var salt, er der rigeligt med Forsteninger. Gletscheren maa have staaet i lang Tid paa samme Sted for at danne en saa stor Aflejring; men naar alpine Gletschere mod Podalen har kunnet danne Moræner paa 600 m, er en Af- lejring som den ved Keasuk ikke saa imponerende. Tet ved Tasiussak treffer man en Morenevold med usorteret Mate- riale, blandt andet sterre Sten. Denne Vold maa have veret det sidste Stadium i Dannelsen. Sandsynligvis er Landet da hevet saa hojt, at det ikke mere laa under Havet. Volden er da at betragte som en usorteret Endemorene. Vegetationen paa disse flade Strekninger er fortrinsvis Lichener, navnlig sorte Skorpelicher — sort er den fremher- skende Farve — eller, hvor Vegetationen er kraftigere, den sorte Busklichen blandet med andre Lichener. Man kan altsaa nærmest kalde den en Lichenhede. Af Phanerogamer var Saai- fraga, Luzula, Poa, Artemisia, Silene, Stellaria, Papaver, Rumex paa sine Steder ret hyppige. Paa saadanne Steder faar vi altsaa en Fjeldmarkvegetation. Hedeplanter er derimod sjeldne. Her og der finder man en Salix, Empetrum og, hvor der er lidt fugtigere, Vaccinium uliginosum. Lignende flade Strekninger traf jeg mod Syd ved Orpig- sok med en iignende Højde. Sandsynligvis har de ‘en lignende Dannelsesmaade, idet Gletscheren i sin Tid har strakt sig frem gennem Søerne. Uden at have været paa Stedet er det rime- ligt at antage, at de af Hammer omtalte flade Strekninger fra Tasiussarssuak og til Havet (Sydost-Bugt) forholder sig paa samme Maade. Forøvrigt vil sikkert en grundig Undersøgelse af disse skalforende Aflejringer ikke blot her i Orpigsôk, men ogsaa de andre nevnte Steder vere af Interesse, idet de 68°37.5 234 maaske kan give Oplysning om Forhold, der vil vere af Vigtig hed for Forstaaelsen af Dannelsesmaaden af disse Aflejringer. Paa medfolgende Kort er de skalforende Dannelser i Orpigsôk aflagt. Efter at vere kommet til Tasiussak naaede vi i et smukt Sommervejr Teltpladsen ved Kunguak. Denne Teltplads har | | | А Srollinende zu 50°41, 5 Fig. 12. en usedvanlig smuk Beliggenhed paa Vejen til Alangordlek, men benyttes ikke videre af Gronlenderne. Kunguak-Dal er udfyldt af en leragtig Moræne. Som saa ofte paa lerholdige Morener er Vegetationen meget aaben, idet den har et maske- agtigt Udseende. Denne nætformede Fordeling af Vegetationen synes at vere et Resultat af Lerets Tilbojelighed ‘til at slaa Revner, naar der om Sommeren indtreder Torke; i disse 235 Revner har Fra og Spirer lettere ved at komme op end i de midterste Partier i Masken, hvor Leret er haardt som et Gulv. Om Foraaret under Snesmeltningen forholder det øverste Lag af Leret sig ganske som en halvflydende Masse. Træder man paa Leret, synker man i til Foden standser ved det frosne Lag. Paa Skraaninger kan man iagttage, at Leret beveger sig som en sejgtflydende Masse. I Søen ovenfor Teltpladsen er den smukke, lille Phalaropus (Odinshene) meget almindelig. Fra Kunguak roede vi den neste Dag til Kekertar- ssunguit-Tupersua. Herfra foretog jeg den folgende Dag en Ekskursion til Teltpladsknuden for at se, hvorledes det for- holdt sig med Gletscheren og Tilstanden i Fjorden i det hele taget. | Fjorden laa der 3 Isfjælde i oprindelig Stilling; det ene af dem laa temmeligt langt ude i Fjorden, de andre to nermere ved Gletscheren, det ene vel omtrent i Midten af Fjorden, det andet noget nærmere Kekertarssunguit. I alle andre Henseender saa Fjorden ud som sædvanligt. Gletscherens Ende laa i det hele paa samme Sted som det foregaaende Aar, nogle Partier havde en mere ostlig, andre en mere vestlig Be- liggenhed end Aaret forud. Hvad der forsaavidt er vigtigere, naar det gelder om at afgore, om Gletscheren trekker sig til- bage eller ikke, er, at den Del af Randpartiet, der glider paa Bunden langs Teltpladsknuden, havde trukket sig noget tilbage; paa det allernærmeste laa den 40 m ostligere end Aaret for. Det forekommer mig, at man i denne Omstendighed har et Bevis for, at Gletscheren fremdeles er i Aftagen. Det kunde jo nemlig tenkes, at Gletscheren allerede havde naaet sit Mini- mum og nu atter var ved at skyde frem. Derefter vendte jeg tilbage til Fjorden, hvor jeg foretog nogle Lodninger. I det hele er Tasiussak ikke ner saa dyb som Torsukatak, hvilket vel heller ikke var at vente, men den er heller ikke saa dyb som Farvandene syd for Torsu- katak, hvilke i flere Henseender kan sammenlignes med XXXIV. 16 236 Tasiussak. Den største Dybde, jeg har fundet i Tasiussak, ег 251 m, omtrent ud for Kunguak; men da Lodskuddet ikke ligger midt i Fjorden, er det muligt, at der kan findes lidt større Dybder. I Farvandet syd for Torsukatak var Dybderne 375 m. Forevrigt er Dybdeforholdene i Tasiussak i det héle temmelig ensformige. Ligesom i Torsukataks Omraade finder man ogsaa her trugformede Fordybninger; en saadan ligger netop uden for Kunguak. Bundens Art er her som overalt i Fjorden en fin Ler; kun enkelte Gange har jeg faaet et Gruskorn eller en lille Sten med op. Nogen videre Vægt paa en systematisk Undersøgelse af Bundproverne lagde jeg for Resten ikke. Efter at jeg havde foretaget Lodningerne, gjorde jeg atter en Udflugt til Isfjorden. De to Isfjælde, der laa nærmest Glet- scheren, var nu skubbet lengere mod Vest og laa næsten uden for Kakapalak. Det tredje Isfjæld kunde jeg ikke finde, rimeligvis var det gaaet itu og omdannet til de sædvanlige Is- fjelde. Ved Gletscheren maa der have fundet omfattende Kalv- ninger Sted; Gletscherenden havde trukket sig noget tilbage. Som omtalt i Beretningen for 1902 kan man meget tyde- ligt i det torlagte Areal ved Nunatap-Tasia adskille to Zoner. I den ene er der allerede en ret betydelig Plantevækst, i den anden og laveste er Planteveksten endnu sparsom. I den overste Zone finder man Rester af udgaaede Pianter netop af det Udseende de faar, naar de er gaaet ud, ved at Stedet er blevet oversvømmet. Jeg fandt saaledes ganske godt bevarede, men udgaaede Mosser; Grene af Salix blev fundet. Alt tyder paa, at den oprindelige Vegetation er bleven kvalt, ved at Vandet er steget; siden er Vandet atter sunket, og en ny Vegetation er da indvandret. Disse Svingninger i Vandstanden staar na- turligvis paa det nøjeste i Forbindelse med Gletscherendens Svingninger. Det er værd at lægge Mærke til, at der altsaa maa have været en Periode, der aabenbart maa ligge forud for 237 Hammers Undersogelser, hvor der har været en lavere Vand- stand, altsaa en ringere Megtighed af Isen. Endnu stod tilbage at foretage en Undersogelse af Sikui- juitok-Fjorden. 1902 gik jeg dertil fra Jakobshavn; men det er en lang Vej. Denne Gang roede jeg til Rodebay, hvorfra Vejen knapt er saa lang, og hvor man oven i Kobet kan ro paa nogle Indsoer. I Kajak roede vi om Eftermiddagen fra Rodebay til Kangersunek-Kingua og bar saa Kajaken langs Perserajoitok-Kugssua til Kangersunek-Taser- sua, hvor vi atter kunde ro et Stykke. Endnu to Gange maatte vi bere over Land og naaede omsider det inderste af Dalstroget. Paa en Skraaning mod Nordvest traf jeg paa en lille Plet den smukke gulblomstrede Ranunculus. Gennem en Dal steg vi langsomt tilvejrs og naaede omsider om Morgenen Kamhojden. PEON Gunes ATO Fig. 13. Fra denne til Gletscheren var der endnu et godt Stykke. Forst ved Middagstid naaede vi frem til selve Gletscheren. Ved at betragte Kalvismasserne ser man snart, at Isstykkerne er meget afenavede, alle Kanter og Spidser ег forsvundne. Et typisk Stykke Is fra Sikuijuitok har omtrent Form som afbildet i Fig. 13. Hojden kan vere storre eller mindre; man kan under- tiden se ganske flade Stykker, ganske lig Vinteris. Kalvisen i Sikuijuitok er heller ikke hvid, saaledes som Kalvis plejer at vere. Den gulgraalige Nuance, Isen i denne Fjord har, ad- skiller den meget fra Kalvisen i andre Fjorde. Denne snavset hvide Farve hidrerer fra Stov, som navnlig om Efteraaret blæser ud paa Isen. Kun i umiddelbar Nerhed af Gletscheren be- merker man et smalt, hvidt Belte af mere uregelmessig formet Kalvis. At Bæltet er smalt, tyder paa, at Gletscherens Kalv- ning kun er ubetydelig. Ispakningen i Fjorden kan altsaa ikke direkte hidrore fra Sikuijuitok-Gletscher; men maa 16* 238 hidrore fra andre Aarsager. Som omtalt i Beretningen af 1902 maa sikkert Jakobshavns-Isfjord vere den egentlige Aar- sag. Den gulgraa Kalvismasse, som udfylder den inderste Del af Sikuijuitok, strækker sig ogsaa langs Vestsiden af Nuna- tarssuak. Nærmer man sig til Jakobshavns-Isfjord, lægger man Mærke til, at Kalvisen efterhaanden faar sit sæd- vanlige Udseende, hvid. Navnlig bemærker man, at et Belte sniger sig tet omkring Natdluarsuk-Halvo og strækker sig henimod Natdluarsuk-Bugt. Man kan vist forklare dette paa den Maade, at Tidevandet, som strommer stærkest om Natdluarsuk-Halvo, tager den Kalvis, som findes iJakobs- havns-Isfjord ud for Sikuijuitok-Fjord med sig ind i denne Fjord. Naar det atter bliver Ebbe, kan Isen ikke komme ud, da Jakobshavns-Isfjord er stærkest pakket med Is. Man kan vist ikke antage, at Kalvismassen direkte bliver presset ind i Sikuijuitok, ellers maatte der ogsaa under Nuna- tarssuak findes hvid Kalvis, med mindre der fra dennes syd- vestlige Hjørne skulde udgaa en Revle, men det er der for- øvrigt intet, der tyder paa. Forholdene er sikkert de samme som i de sydlige Bifjorde, Kangerdlukasik og Tasiussak. Ogsaa her driver Kalvismasserne ind, naar det er Flodtid; i begge Bugter er Mundingen smal; i Kangerdlukasik er Mundingen delvis lukket af en Ø. I begge Fjorde kommer der derfor ikke saa megen Drivis ind som i Sikuijuitok, der har en vid Munding. For Tasiussaks Vedkommende kommer der hertil, at dens Overflade er saa stor, at Afsmeltningen af Is- bjergene langt overgaar Tilforselen. Sikuijuitok-Gletscher er lav; paa den sydlige Side er Hoj- den c. 20 m, paa Nordsiden mindre; et lille Parti nermer sig dog stærkt til at vere 20 пт’ For at faa en nojagtig Angivelse af Snegrensen, der bedst kan bestemmes paa denne Aarstid, sejlede jeg til, efter at vere vendt tilbage til Rodebay, til Kekertak og derfra til Asa- sat for at bestige Asäsat-Ka. Asasat selv er et forvitret 239 jernholdigt Parti. Opstigningen sker i en Kloft, som er op- staaet ved Forvitring, og som med sin rislende Bæk og frodige Vegetation danner et smukt Parti. Paa den Veg af Kloften, der vender mod Havet, ruger mange Maager. I det lille Delta, som Bækken danner, var Stenhammaria ikke sjælden. Opstig- ningen er ikke vanskelig; i Lobet af en Time naaede vi Pla- teauet. Betula forsvandt i en Hojde af 360 m, og noget hojere forsvandt Salix glauca (475 m). Vaccinium uliginosum Тог- svandt i en Hojde af 560 m. De andre Hedeplanter holdt sig endnu: jeg saa Diapensia, Loiseleuria, Dryas, Silene acaulis, Luzula samt mange Mos- og Lavplanter. Efterhaanden bliver Hedeplanterne sjældnere. Cussiope er nu den almindeligste Plante. Paa Partier med mere Bundfugtighed fandtes den lille sirlige Cassiope hypnoides. Salix og Syre fandtes endnu. Den sidste Cassiope saa jeg ved 780 m. Allerede for denne Højde fandtes spredte Snepletter; nogle af disse var dog meget tynde og forsvinder maaske i gunstige Somre. De tykkere maa dog anses for at vere vedvarende. Den lokale Snegrense kan sættes til 700m. I en Hojde af 690m traf jeg temmelig store Snepletter (7 m lange og 3 m brede). De laa bag ved en lav Klipperand med sydlig Eksponering. Paa den gamle Sneskorpe var aflejret et tyndt Lag nyfalden Sne — vi var sidst i Juli. — Denne lave Snegrense skyldes formodentlig den Omstendighed, at under Snefog fra Nord lægger Sneen sig her i megtige Driver. Til Gengeld ligger Stedet rigtignok lige mod Syd. Den egentlige Firn, som bedækker Toppen, begynder forst ved 850 m. Højden af den tvedelte Top er 895 m for den sydlige og 910 for den nordligste. Fra den nordlige Top mod sydost er Faldet meget sterkt, saaledes at Firnranden her ligger ved 700 m. Randen af Firnen er her ledsaget af en Morenevold; paa sine Steder var denne Morenevold fjernet 20—30 m fra den nuve- rende Isrand, en Antydning af Isens Tilbagetrekning. Firnens Overflade er ganske jevn og om Natten haard, saaledes at den er let at gaa paa. 240 Nogle Dage senere besteg jeg Nakarajok, en isoleret Top paa Nugssuak Vejens Vestside. Paa det flade Land tæt ved Strandbredden ligger der en lille Vold, Arfiussak (af arfek Hval og ussak lignende). Den blev ikke nærmere undersogt og er vel sagtens en Strandvold og ikke nogen Endemorene, hvilket ikke passer godt med Beliggenheden. Op- stigniugen er ogsaa her ret let. Planterne forsvinder næsten i samme Orden og i samme Hojde som ved Asasat-Kula. Snegrænsen ligger dog her noget hojere, idet kun et lille Parti af Toppen var bedekket med Sne. Firngrensen laa ved 885 m; mod Nordest laa dog Firnen noget lavere, fordi den her var i Bevegelse. Snegrensen laa altsaa paa Nakarajok i det hele lidt hojere end paa Asäsat-Kä. Maaske beror dette paa, at Sneen paa en lille isoleret Top lettere blæser bort end paa et sterre Plateau. Jeg havde haft til Hensigt endnu en Gang at gere en Ekskursion til Gletscherne i Torsukatak, men uheldigvis var Fjorden paa Grund af sydvestlig Vind saa fyldt med Kalvis, at det var umuligt at komme frem med Konebaad. Efter forgæves at have ventet paa Lejlighed til at komme ind i Torsukatak, brød jeg op for at vende tilbage til Jakobshavns-Isfjord; jeg blev ledsaget af Udliggeren i Kekertak, der fortalte, at endnu 1885 laa der en lille Firn paa Niakornak-®; tidligere havde den været endnu større, hvilket Udsagn blev bekræftet af Grønlænderne; men da Niakornak næppe er mere end 400 m, er der ingen Grund til foreløbig at tillægge dette Udsagn nogen Betydning. Mere rimeligt er det, at Glet- scheren ved Kingussak tidligere har haft en større Udbre- delse end nu. Ved Ankomsten til Jakobshavns-Gletscher iagttog jeg, at denne havde slaaet en stor Revne nord for den vest- lige Basisvarde. En smallere Revne gik i nordøstlig Retning omtrent fra Nunatakens Vestspids til den sydlige Ende af omtalte store Revne. Det var ikke muligt at iagttage nogen 241 Hojdeforskel paa de to Sider af Kloften. Heiler ikke da Kloften var blevet noget bredere, var det muligt at paavise nogen For- skel i Højde af Isfjæld — thi det er man berettiget til at kalde den Del af Gletscheren, der laa vest for Kløften — og selve Gletscheren. Derefter maa den af mig allerede tidligere paa lagttagelser grundede Teori, om at Jakobshavns-Gletscher flyder paa Vandet med sin yderste Ende, og at Kalv- ningen her finder Sted, ved at der fraskilles Stykker af samme Megtighed som Gletscheren selv, bestyrkes. Kalvning ved Opdrift eller Nedstyrtning finder kun Sted for mindre Isfjældes Vedkom- mende. De store Isfjælde gaa dog altid itu, inden de naar Banken. De paa denne faststaaende Isfjælde er derfor Brud- stykker uden den Гог Isfjældene i oprindelig Stilling karakteri- stiske Overflade. Sporgsmaalet, om hvorledes Jakobshavns- Gletscher kalver, maa derfor anses for at vere opklaret. Endnu laa den smalle, sorte Rand tvers over Nunatap- Tasias Munding. Om nogle Aar vil denne Bariere rimeligvis forsvinde, og Nunatap-Tasia vil da for en Tid vere en Bugt til Jakobshavns-Isfjord. De tidligere omtalte Isfjelde i oprindelig Stilling var nu presset mod Vest og stod omtrent uden for Tasiussaks Munding. For at faa en Forestilling om, hvor dybt Jorden tør op, lod jeg foretage en Gravning i det løse Materiale ved Keaku- suk. Resultatet var 1,7 m. Paa et andet og mere fugtigt Sted fandt jeg, at Dybden fra Jordens Overflade til den frosne Jord var 1,5 m. Forsøget blev anstillet midt i August, altsaa paa en Tid, hvor Varmen maa have naaet sit Maximum i Ret- ning af at naa ned. Paa en Ekskursion til Eke lagde jeg Mærke til, at der nu mellem Isfjorden og Klavshavn findes 3 Bopladser, nemlig Narsarmiut med 6 Huse, Kaersormiut med 2 og Eke med 3. Paa Hammers Tid var der kun en Boplads, Igdlor- miut; i det mindste angives kun denne påa Hammers Kort. Narsarmiut betyder dem, der bor ved Sletten. Der findes nemlig Nord for Klavshavn mellem Fjeldene og Havet en smal Slette, der i meget minder om Sletten ved Keakusuk, og som maaske staar i Forbindelse med Jakobshavns-Glet- scher, da denne sked sig helt ud gennem Fjorden. Minder om den Tid har man ogsaa i Rudimenter af Endemorener, der findes paa den nordlige Side af Fjorden. Forøvrigt har jeg ogsaa ved Torsukatak fundet saadanne Rester af en Ende- moræne paa Halvøen ved Nugak. Om disse Endemorener er samtidige og samtidige med de store Aflejringer ved Enden af Tasiussak, Orpigssok og Overgangen mellem Sydost- Bugt og Tasiussarssuak lader sig endnu ikke afgore; men hvis de gor det, henpeger de paa en af de mindre Istider, der har fulgt efter den store Istid, da hele Gronland var over- iset. Om Isfjeidsbanken er at opfatte som den daverende Jakobshavns Gletschers Endemoræne, er vel tvivisomt. 20121909: Appendix. List of Vascular Plants collected by Dr. М. ©. Engell in the Vicinity of the Great Glacier of Jakobshavn, about 69° lat. n. Determinated by Morten P. Porsild. During his journey to Greenland 1902 for geographical and geological studies, Dr. Engell brought together a small collection of plants, principally gathered in the neighbourhood of Jakobshavn. At his request, I have determinated them and as this part of Greenland, visited by Dr. Engell, has not been much investigated botanically, it seems to be of some interest to give a list of all the plants collected. The localities, where the plants were found, may be found on the map of M. С. Engell (Meddelelser om Grønland XXXIV, tab. II) with exception of one, viz. Orpigssuit or Orpigssôk («the place with numerous thickets») lying at 68° 35’ (Medd. om Gronl. XXVI, tab. III). For the physical conditions of the soil, habit of the vegetation etc. we may refer to a paper of the collector in Medd. om Gronl. XXVI. After the MS. 1906 of the following list was written, Dr. Engell has looked over it and added some species and localities to it. Those statements, of which I have not seen the plants, are set in « —». «Equisetum arvense L. Tasiussak, common». «Cystopteris fragilis (L.) Bernh. Tasiussak, common». Woodsia ilvensis (L.) B.

Hence its northern limit on inland stations lies about 11/2 degrees farther northward, than near the open coast. The same is the case with another plant of southerly distribu- tion, found at Orpigssuit viz. Gentiana tenella (С. Hartz Medd. om Gronl. ХУ, р. 40). «Alopecurus alpinus Sm.

IE The Eskimo tribe, which is called here the Polar Eskimos, lives on the north-west coast of Greenland, between 76° and 79° N.L., and is the most northern people on the globe. From the West Greenlanders they are separated by the uninhabited ice-shores of Melville Bay and from the natives of Ponds Inlet on the northern part of Baffin Land by the likewise uninhab- ited large islands of Ellesmere Land and North Devon. The title ‘‘neighbours of the North Pole’, which E. Astrup gives them, is theirs with right, not only because their land is so near to the pole, but also on account of the great and important help they have given in recent times to the Polar expeditions. For a long time they were known under the name ‘the arctic Highlanders”, a title given them by John Ross, by which he intended to convey the impression both of remarkable stature and also of the northerly and mountainous nature of their land. Later, Bessels with small reason intro- duced the name Itaner or Etah’er from the most northerly, large settlement of the tribe, Ita or Etah. More frequently the tribe has been named after their most southerly settlement the Cape York Eskimos. The title Polar Eskimos has come into use mainly since L. Mylius-Erichsen’s Danish Expedition of 1902—1904. Although there is full reason to regard the tribe as an ethnographic unit, owing to the apartness of its region from that of all other Eskimos and owing to the special character- istics of its culture, yet its numbers are extremely few. Ас- 256 cording to a census taken by Peary in the summer of 1895 the tribe then numbered 253 individuals in all, of which 140 were of the male sex and 113 female. Already two years later the number had sunk to 234. And in 1906, when Peary again made a census of all the natives, he found there only 207, of which 119 were men, 85 women and 3 small children, of whose sex Peary could obtain no information. These numbers, which also agree with the observations of the Danish Expeditions, are certainly correct. On the other hand, the estimates given by Kane in 1854, of about 150, and by Hayes in 1861, of about 100, and by Bessels in 1873, of 112, were certainly incom- plete. It was so long ago as 1616, that William Baffin in his small ship “Discovery” sailed along this part of the Greenland coast, past Capes York, Atholl and Parry, and on the 5 of July reached his furthest point, within sight of Cape Alexander. Baffin narrates, that he was forced by the ice ‘‘to stand backe some eight leagues to an island we called Hakluit’s [le — it lyeth betweene two great Sounds, the one Whale Sound, and the other Sir Thomas Smith’s Sound; this last runneth to the 06 02 182...’ We must pass over two hundred years, however, before we learn anything of the inhabitants of this land. They were first discovered in 1818 by John Ross. On the 9 of August, while the two ships of John Ross were lying in the neighbour- hood of Cape York, 18 natives visited them, approaching over the ice. They had sledges and dogs, lances and knives, con- cerning which Ross says, that they were made of meteoric iron, said to occur in abundance in the neighbourhood of Bushnan Island. Ross adds, further, that they apparently had no idea of other people living to the south’. 1 The voyages of W. Baffin of 1612—22, ed. by C. R. Markham. Hakluyt Society. London 1881, p 145. 2 John Ross: A voyage of discovery etc. London 1819. John Ross’ voyage and in still higher degree W. Е. Parry’s in 1819, during which Lancaster Sound was navigated, led to the English and Scottish whalers pushing further north than they previously had done. Baffin’s voyage in 1616 had been the precursor of the whale-fishing in the Davis Strait, which was begun already in 1619 by the Dutch, followed by the English a few years later; but for 200 years the whalers had kept to the southern parts of the Greenland coast. After Ross and Parry better knowledge was obtained of the movements of the whale in these waters, and the whalers were not long in making use of this knowledge. In March the large whales, with which we are here concerned, are met with off the ice-edge at Cumberland Sound and Frobisher Bay. In the beginning of May they go over to the Greenland coast, where they are found in June south of Disko. From here they return towards the north along the ice-edge in Melville Bay and into the so-called ‘‘North Water” of the whalers, south of Smith Sound between Greenland in the east and Ellesmere Land in the west. Late in July and in the beginning of August some are met with in Jones Sound and in Lancaster Sound, but the main portion are found off the mouth of Ponds Inlet, where the whale-fishing takes place. In September and October the whales turn to the south between the coast of Baffins Land and the western edge of the ‘‘middle pack’ !. The movements of the whalers correspond with the mi- grations of the whale. They arrive at the North Water late in June or in the beginning of July, and often come into connec- tion, as a rule off Cape York, with the Polar Eskimos, who come out to the ships on the coastal ice which is still firm at this time of year. During the past century the whalers have thus traded occasionally with the Polar Eskimos, who in return for their fox and bear skins received wood and iron implements. ' А.Р. Low: Report on the Dominion Government Expedition to Hudson Bay and the arctic islands, 1903—04. Ottawa 1906. 258 On the other hand, the stay of the whalers in the North Water has always been so short, that they have never come into such close contact with the Polar Eskimos as, for example, with the Eskimo tribe at Ponds Inlet, who to some extent have taken part in the whale-fishing. Fortunately, the English and Scottish whalers have never adopted the methods employed by the American whalers in Hudson Strait and in Hudson Bay. These latter, namely, em- ploy the Eskimos to man their whaling-boats and for this pur- pose carry away whole, small tribes to the fishing-grounds, to exploit their powers and cleverness throughout the summer. On the other hand, the English and Scotch depend wholly upon their own white crew to man their boats. The introduction of steam-power on the whaling vessels, in the fifties or sixties, gave a fresh impetus to the whale-fishery and for the Polar Eskimos this meant a closer connection with civilisation. Almost at the same time the whole of the fishery in Baffin Bay passed over into the hands of the Scotch alone, who came from a single port, namely Dundee. From there about half a score of vessels went yearly in the seventies to Baffin Bay, but in 1903 and 1904 only 4 vessels went out and in 1909, it is said that only a single vessel visited Baffins Bay. The Polar Eskimos had no connection with the scientific expeditions for a long period of years after their discovery. It was only during the expeditions in search of Franklin that they became better known. The ship “North Star” under the ship- master Saunders, which was sent out in 1849 with provisions for James C. Ross’ Search Expedition in Barrow Strait, was prevented by ice from entering Lancaster Sound and had to pass the winter of 1849—50 in the small North Star Bay on the south side of Wolstenholm Sound. In the middle of August 1850 the two large English exped- itions under H. Austin and William Penny both came into connection with the Polar Eskimos at Cape York. The last- 259 named had the Dane Carl Petersen on board as interpreter. From Cape York Austin’s expedition took a young Polar Eskimo to England, where he was baptised and became known under the name of Erasmus York; he died however in the year 1856 at Newfoundland, where he was being educated to be a mission- ary among the Labrador Eskimos. Regarding the Polar Eskimos at Cape York Lieutenant Sherard Osborn!, who was in charge of one of Austin’s ships, narrates that they arrived in dog-sledges, which ‘‘were entirely constructed of bone, and were small, neat looking vehicles; no sledge had more than five dogs; some had only three ... They are said, ... to have believed themselves to be the only people in the world’. Carl Petersen? says, with regard to one of these sledges, that it was bound together by thongs of all kinds. The runners consisted of old whale-bone, and there was but little wood in it. In the years immediately following, the English expeditions again came into connection with the Polar Eskimos. The only one of importance in this regard is the expedition under E. A. Inglefield, which discovered Inglefield Gulf and for the first time sailed through Smith Sound. On August 2214 1852 Inglefield®> met Eskimos in the neighbourhood of the Petowik Glacier, where they were bird-hunting among the cliffs by the coast; “Nothing of European ware was found with these natives, nor were kyacks seen”. Thereafter he visited the Eskimo settle- ment Umanark, which was uninhabited at the time, as also a likewise uninhabited winter-settlement (probably Netschilivik) on Barden Bay, in the neighbourhood of which, however, Eski- mos were dwelling in tents; at this settlement several examples of European steel implements were found. 1 Sh.

London 1853, р. 46 et seq. 260 Inglefield’s discoveries were continued by the American Expedition under E. K. Kane. From the autumn of 1853 to late in May 1855, when the members of the expedition left their ship to try and reach Upernivik by boat, they had their fixed quarters in Rensselaer Harbour (78°37' N.L., 71° М. L.), and as time went on came into close touch with the Polar Eskimos. A part of the expedition, including Carl Petersen and 1. I. Hayes, which had made a futile attempt to reach Upernivik by boat in August 1854 and had been obliged to live for some time in a stone-hut on the coast between Booth Sound and Granville Bay, would certainly have perished from hunger, if the Polar Eskimos had not come to their assistance, and thus enabled them to get back to their ship in December". Kane? was the first to give a detailed account of the Polar Eskimos. From his description we obtain a vivid picture of their poverty in wood and iron. The shafts of the har- poons were composed of several pieces of wood bound together. The sledge-runners were made of pieces of bone fitted and bound together. Pieces of barrel- hoops were used for knives. It appeared further, that the Polar Eskimos did not at that time hunt the herds of reindeer, which collected round about on the coastal hills, nor did they know anything of the bow and arrow. The salmon in the lakes and rivers were not fished and they were unacquainted with the usual Eskimo me- thods of fishing, with a three-pronged fork. Further, they did not use the kayak, concerning which Kane says, that it ‘‘exists among them only as a legendary word” >, Kane’s interpreter, the Danish West Greenlander, Hans Hendrik", left the expedition during the return voyage and 1 Isaac I.

Hayes’ expedition found him at Cape York on August 95 1860 and took him onboard with his wife and child, to serve as interpreter. The winter of 1860—61 was passed by the expedition in Foulke Fjord at Etah and they thus came into close contact with the Polar Eskimos. Regarding these, Hayes like Kane narrates, that they did not hunt the reindeer, as the bow and arrow were unknown to them!. A few years after Hayes’ stay among them, however, the Polar Eskimos must have learnt not only reindeer-hunting and the use of the bow and arrow, but also salmon fishing and the building of kayaks, as well as the methods of hunting from the kayaks; this learning they received from a tribe of immi- grants from the American side of Smith Sound. About half a century later Knud Rasmussen” obtained the story of this immigration from two Polar Eskimos, namely, from Merkrusärk, who was born on the American side, and from Panigpak, whose father Itsukusuk was son of Kridlarssuark (i.e. the great Kridlak), who was leader of the immigrants. These seem to have numbered in all ca. 14 persons; but after some years — Merkrusärk said 6 — the old Kridlarssuark had the desire to return to his own country and again left the Polar Eskimos along with his relatives, with exception of his own son Itsukusuk and his family. During the journey, how- ever, most of the party succumbed to hunger; some of them committed cannibalism and only a few survived, to return 5 years later to the Polar Eskimos; amongst these was Merkrusärk. For various reasons I am able to say, that this immigra- tion took place in the beginning or the middle of the sixties. When C.F. Hall’s expedition “Polaris” lay at Life-Boat Cove in the neighbourhood of Etah during the winter of 1872—75, Captain Budington happened to notice a tattooed woman and 1 Isaac I.

They had introduced the use of the bow and arrow’?. The husband of this woman was indeed Itsukusuk (pro- nounced Itukusuk), as Knud Rasmussen, using the Danish- West Greenland mode of writing, calls him — the American authors write the name E-took’-a-jeu — and her little son then was Panigpak (Pun’-e-pa). The ‘4 or 5 years before”, given as the time for the last immigration, must certainly not be taken literally. There are other inaccuracies also in Budington’s information; thus, he states, that they passed over Smith Sound in a woman’s boat and 5 kayaks, whereas Merkrusark narrates, what is certainly correct, that they came over the frozen Strait, thus on dog- sledges, bringing their kayaks on these. Merkrusark’s report gives one the impression of being correct on the main points. The narrative of the expedition shows, however, that the departure under the leadership of the old Kridlarssuark must have taken place before 1872, since Itsukusuk with his family alone remained. We may likewise conclude, that Merkrusark and the few others, who were saved on the eventful return- journey, had not yet come back again to the Polar Eskimos. if we now calculate, that they could have returned at the ear- liest shortly after the departure of the ‘‘Polaris” Expedition from the Life-Boat Cove in June 1873, and make use of Mer- krusärk’s statement of the 5 years as given above, the depar- ture on the return-journey to the American side must have occurred at the earliest in 1868 and at the latest on the spring- ice of 1872. The time for the first immigration must therefore lie between 1862 and 1866; but I believe that the first year mentioned is nearest the mark. 1 С.Н.

Washington 1876, рр. 450—451. 263 | base this view chiefly on the interesting fact, that Ме Clintock’s Franklin-Expedition obtained information regarding Kridlarssuark and his little tribe, whilst these were on their way from their home-country to the coasts of Smith Sound. After a fleeting connection with the Polar Eskimos at Cape York on June 26 1858, Mc Clintock on his Franklin Search Expedition with the ‘‘Fox” sailed westwards and later southwards from Jones Sound along the east coast of North Devon; here, at Cape Horsburgh, the most easterly point of North Devon or more correctly of Philpots Island, he met Kridlarssuark on July 021858: - Ме Clintock! is himself more brief in his report of this meeting than his interpreter, the above-mentioned Dane Carl Petersen”, for which reason I keep mostly to the account of the latter, which agrees in all points with Mc Clintock’s. Whilst the ‘Fox’ was passing a good distance off the edge of the fixed ice, Mc Clintock heard some voices calling from the ice through the still weather, and shortly after caught sight of some figures. After anchoring to the fixed ice, 3 men, 3 women and 2 children came on board, whilst 4 persons re- mained behind on the shore. Carl Petersen then narrates that “they were all clothed in reindeer skin and quite resembled our Greenlanders, and their language had also a considerable resemblance to that of the latter Eskimos’. Their coat was however somewhat longer than the Polar Eskimos’; the faces of the women were tattooed. They asked Mc Clintock to wait, as their sledges were on the way with narwhal and walrus teeth, which they wanted to sell. They had come from Ponds Inlet, where they had often been on board the English whaling- vessels. Two years previously they had come over Lancaster ' Me Clintock: A Narrative of the Discovery of the fate of Sir John Franklin.

This Kre’tlak cannot be any other than Kridlarssuark, who has grown to be a great figure in the folk-lore of the Polar Eskimos. All doubt of his identity disappears when we learn what Panigpak told Knud Rasmussen regarding his great grand- father. ‘‘His hair was thin like the white men’s. His large forehead was not covered by hair’. A more certain proof of identity, when it shows an extremely rare characteristic among Eskimos, we could not desire. When we think of the length of time such a journey would take under a constant struggle for existence, it seems very probable, that 6—7 years passed during which the little group of emigrating, Ponds Inlet Eskimos wandered along the east coasts of North Devon and Ellesmere Land, before they reached their distant, uncertain goal, the Northern Eskimos, of whom they had heard from the whalers. I believe myself fairly near the truth, in saying, that it was most probably the year 1862 or 1863. when the culture of the Polar Eskimos received the many new impulses from their immigrant kinsmen. The English Expedition of 1875—76 under G. Nares did not touch the land-region of the Polar Eskimos on the voyage up to Floeberg Beach on the coast of the Polar Ocean itself; on the return voyage the ship of the Expedition entered Bardin Bay on September 12% 1876 and saw there an Eskimo land- settlement, but as the wind went round it was obliged to hasten out to sea, without coming into connection with the Eskimos, who were already streaming to the beach’. The American Expedition of 1881—1884 under A. W. Greely? has most interest in this conneetion, as it discovered Lake Markham: The Great Frozen Sea. London 1880, p. 359. нА. |. 2 А. W.

At this lake, namely, the remains of Eskimos winter-houses were found, a most astonishing find, which showed, that an Eskimo tribe must have lived here in the extreme north; not only this, but also thal they must have lived inland during the winter, whereas the rule is that the Eskimos must remain on the sea-coast, in order to obtain subsistence by seal-hunting on the ice. These important discoveries regarding the earlier places of settlement and lines of migration of the Eskimos over the most northerly Polar islands, especially on the west coast of Ellesmere Land and North Devon, were continued by the Norwegian Expedition of 1898—1902 under the leadership of O. Sverdrup. In 1891 Robert Peary began his long series of expeditions and lengthy sojourns among the Polar Eskimos. In this way the culture of the Polar Eskimos was once again enriched, which has contributed undeniably to lighten their struggle for existence. Thus, in exchange for fox and bear skins they ob- tain weapons of the finest and best American manufacture, and Peary by his frequent expeditions could keep them fairly regu- larly provided with ammunition. They had never had much advantage out of the few weapons, they had previously been able to acquire in exchange from the whalers, as it was only very occasionally that they could procure powder and shot. Peary's first expedition passed the winter of 1891—92 al Mc Cormick Bay and the second of 1893—95 at Bowdoin Bay, which lies a little more to the east on the north side of Ingle- field Gulf. The expeditions of 1896 and 1897 were only summer voyages, to fetch the large blocks of iron, which Ross had heard about as occurring in the neighbourhood of Cape York. On his fifth expedition in 1898—1902 Peary began to make his way right up to the northern end of the Smith Sound Passage with his ship, and at the same time he began to fol- low the example of the American whalers in Hudson Bay, 266 taking with him a number of Polar Eskimos on board the ship, in order to make use of their powers and cleverness in hun- ting and managing the sledges. He employed the same procedure in 1905—06 and 1908—09. On the first of these expeditions ca. 70 Polar Eskimos or one- third of the whole tribe were taken on board. On the return- journey late in August 1906, 8 of the Eskimo families became discontented over a slight, compulsory reduction in the day’s rations and left the ship in Lady Franklin Bay. These families passed the winter in the region by Lake Hazen west of the Robeson Channel. In the following spring, they journeyed over the sea-ice down to the Etah country, where Knud Rasmussen shortly after found them in the best of condition and health after the long journey, which owing to the lack of dogs had for a great part to be made on foot!. In August 1907 the American Whitney's hunting expedition, with Frederick A. Cook on board, came to the district about Smith Sound. Cook passed the winter in Anoatok north of Etah and started from there on his journey. His main inter- rest for us here, however, is that he showed the Polar Eski- mos the way to the musk-ox. hunting grounds on the west coast of Ellesmere Land discovered by Sverdrup. In May 1909 he again left the Polar Eskimos and journeyed southwards over Melville Bay. From April 1903 to late in January 1904 the Danish, so- called ‘‘Literary-Expedition” under L. Mylius-Erichsen, Grev Harald Moltke and Knud Rasmussen lived among the Polar Eskimos, for the most of the time on Saunders Island. In recognition of the support received by the Expedition from the natives, the Danish Government sent them valuable presents of guns, ammunition, tools etc., which were brought to the Polar Eskimos in the beginning of August 1905 by Captain H. Schouby, 7 В. Peary: Nearest the Pole. London 1907, р. 253. — Knud Rasmussen: Berlingske Tidende, Nr. 181. København 1908. 267 on board the old ship of Me Clintock, the “Fox”, which is now a coast steamer in Greenland. From April 1907 till the end of May 1908 Knud Rasmussen was again with the Polar Eskimos, living ‘‘as Eskimo among the Eskimos”. In the summer of 1909 a Danish Missionary Society commissioned Knud Rasmussen and H. Schouby to found a permanent Mission Station at North Star Bay. The expedition on board the S/S ‘‘Godthaab” also called in at Cape York, both on its outward journey in July and on its return in August. Some scientists who were sojourning in West Greenland at that time, namely, Chr. Refsaas, ethnologist in music, Th. Thomsen, Eskimo archeologist, and the author, also ac- companied the Expedition on the ‘“‘Godthaab”. The main ob- ject of the first-named was to make a collection of the primitive melodies of the Eskimos, which might serve as a valuable supplement to the collections of folk-lore and ethnological materials, made by Knud Rasmussen among the Polar Eskimos. For the Danish National Museum, Th. Thomsen bought up a collection of clothing and implements, an account of which will probably be published by him. My own studies were directed more to the manners and customs of the Polar Eski- mos, and the results of my observations are discussed in the following pages. | To supplement my own observations and for the purpose especially of giving a more complete picture of the life of the Polar Eskimos throughout the year, | have made use of the literature available, among which may be specially mentioned the works of R. Peary, L. Mylius Erichsen and Knud Rasmussen. From the last I have also received various items of information by word of mouth. XXXIV. 18 DIE The region of the Polar Eskimos, in its more restricted sense, is the west side of the broad peninsula, sometimes called Hayes Peninsula, which from North-West Greenland ex- tends towards the west between the Kane Basin in the north and Melville Bay in the south. This western coast, which extends over about 3 degrees of latitude from Cape Olsen to Cape York and which is washed by the “пог water” of the whalers as also by the 50 km. broad Smith Sound, is a characteristic transverse coast with deep and branching bays. The two main fjords are Wolstenholm Sound and Inglefield Gulf. Numerous glaciers project out from the inland ice, so that the narrow, ice-free foreland is split up into small parts. The direction of this coast as a whole is from NW. to SE., whilst the opposite coast of Ellesmere Land has a direc- tion from NE. to SW. Together the two coasts form the funnel-shaped outlet of the long, narrow passage, which con- nects the Polar Sea with Baffins Bay. With regard to the currents the conditions in Smith Sound are quite the same as in Bering Strait or in the northernmost part of the At- lantic between Greenland and Norway; a cold polar current carrying masses of ice goes southwards along the west side of the Sound, whilst a warmer aud ice-free current coming from the south tries to force its way in along the east side. This condition of the currents is directly connected with the revol- ving of the globe, whlch induces the deflection of the water- masses just as of the air-currents. 269 From Melville Bay and the east coast of North Devon to- wards the south and as far as a line from Cape Russell to Buchanan Bay towards the north, both coasts of Smith Sound Passage consists of primitive kinds of rocks, whilst the nor- thern continuation from Kane Basin to Robeson Channel is bounded by coasts which are built up of formations chiefly originating from the Cambrian, Silurian and Trias periods. In agreement with the American geologists, who distinguish between an older, Laurentian and a younger, Huronian group among the primitive rocks, the southern part mentioned may be said to consist of both groups. The older, harder, Lauren- tian gneiss and granite form the coast on the Greenland side from Melville Bay to Cape Atholl and from Foulke Fjord to Cape Russell, while they constitute the whole of the opposite coast of Ellesmere Land and North Devon with exception of a part ca. 40 km long immediately south of Cape Isabella. The Laurentian coast is of a uniform height and shows few indentations, whilst the Huronic coast, which includes the small stretch at Cape Isabella as also the Greenland coast round Inglefield Gulf and Wolstenholm Sound, is more indented as well as more diversified and changeable as regards height and steepness. ‘‘A series of bedded rocks consisting of several thousand feet of sandstones, limestones and other sediments, occupies the coast and islands of the east side of Smith Sound, from Cape Atholl northward to Foulke Fjord. These bedded rocks are associated with dark coloured traps and diabase, which are present in the form of sills between the bedding ; as dikes cutting the bedding rocks and as large intrusive masses.” ! On the Huronic coast also, more frequently than on the Laurentian, we find a low beach which is specially suited to ' А.Р. Low: Report on the Dominion Government Expedition to Hudson Bay and the Arctic Islands on Board the D.G.S. Neptune 1903—1904. Ottawa 1906, p. 207. 18* 270 the building of the winter-houses of the Eskimos, as also for landing, both with the kayak in summer and with the dog- sledges from the sea-ice in winter. This is one of the rea- sons why the buildings of the Eskimos are mainly found at Inglefield Gulf and Wolstenholm Sound, and it is also one of the conditions which make the Greenland coast more inhabi- lable in contrast to the coast of Ellesmere Land. А further advantage which the Greenland coast has in biogeographical regards may also be mentioned here, namely, that many of the high, in part precipitous, in part strongly sloping coast-hills between Cape York and Cape Alexander on Smith Sound are directed towards the south and south-west. This has the result amongst others, that these coasts are spe- cially selected by the birds, and in summer we find this coast teeming with bird life. Chief among these are the Auk and the considerably smaller Little Auk (Mergulus alle L.); less numerous are the eider ducks, gulls, terns, fulmars and loons (Colymbus). Auk grounds occur at some few places where the slope of the coast is steep; the largest and the one most frequented by the Eskimos lies on the south-west coast of Saunder’s Is- land, and the Eskimo name for the island, ‘‘Agpat”, is an indication of the quantities of auk there. A second auk ground, also called ‘‘Agpat”, is found further to the south on the coast right opposite Conical Rock. The Little Auk occurs on the less steep coastal cliffs, where it breeds amongst the stones. The whole coast from Cape York Bay to Cape Atholl, the south coast of Northumberland Island as also the stretch of coast from the settlement Krana on the north side of Inglefield Gulf westwards right round to Kane Basin, might also be con- sidered a continuous row of Little Auk grounds. If we row along such a place on a summer's day the air is full of flocks of birds and noisy with the half chirping, half crackling sounds they make; the sea also is covered with thousands of the 201 swimming black birds. It is only the sea-birds which are of economical importance to the Eskimos; the ptarmigan is only hunted and eaten in times of want; the raven, on the other hand, which also occurs here, plays the part of a mystic messenger in their tradition and folk-lore. | As a consequence of this bird-life, the soil on the south- ern slopes is naturally, owing to the good manuring, very fertile, and we thus find at these places a comparatively luxur- iant vegelation, consisting mainly of grass. And when we find a specially abundant vegetation in these regions, we may be sure in most cases, that it has developed just at one of these bird-grounds with southerly exposure or round an old settlement where the soil has been manured by blubber and offal. The vegetation leads to a considerable wealth of polar hares, and the reindeer also finds here a good part of its food in summer when it comes down from the inner hilly regions. Further, the presence of the birds and hares means a livelihood for a large number of foxes, especially of the blue arctic fox. It seems to be a rule, that most of the blue foxes are met with east of Smith Sound, whilst the white fox is more common on Ellesmere Land. It is quite possible, that this stands in connection with the difference in the food con- ditions, the Greenland side having large quantities of birds, whereas on Ellesmere Land the principal food of the fox is of quite a different kind. Naturally the hares, reindeer and foxes are not exclusively restricted to the districts frequented by the birds, but occur everywhere on the narrow strips of ice-free land between the coast and the inland ice; they may even penetrate in on the Nunataks. A specially rich district for the packs of reindeer is the inner parts round Olriks Fjord, where the most extensive stretches of lichen vegetation are found. These connected conditions have the result, that the coast mentioned has a better vegetation and a richer animal-life than any other place in the same latitudes on the globe. This also leads to better conditions for human life and also helps to ex- plain why it is that human beings have here pushed farthest up towards the pole. The chief conditions for Eskimo life have to be sought, however, not on land but on the sea, and they concern the marine mammals and the ice. The large whales, which still visit the ‘‘North Water” now and then, though in earlier days they must have been present in much greater numbers, have never been of any great importance for the Polar Eskimos. The latter have seized upon the carcases driven on land and revelled in the rich quantities of flesh and blubber, but they have never known how to carry on the systematic ‚hunling of the large animals. The narwhal and the white whale are common and are hunted from the ice and from kayaks; but both;of these im- portant animals go down in winter to more southerly latitudes. The chief source of food for the Eskimos is however the wal- rus, which is met with the whole year round. In the summer time it can be seen lying in the sun on the ice-floes right inside the fjords and at the islands; in the autumn when the fjords are frozen it is met with outside the ice-margin, and through the winter it keeps in the always partially open water in the middle of the North Water due south of Smith Sound and Cape Alexander. The commonest of the seals is however the fjord seal (Phoca foetida, esk. netchik), which occurs throughout the whole year. Phoca barbata (esk. ugsuk) is also found here but in much smaller numbers. It is the first-named, the fjord seal, which comes into the fjords in winter under the even winter-ice and gives rise to the important ‘‘Maupok” hunting at the breathing holes, which this seal constantly makes in the ice. As the Polar Eskimos also hunt the walrus from the ice- margin in the winter, the Maupok hunting is however not of such importance here as is the case amongst some of the 273 arctic: Eskimo tribes on the coast of the American continent, e. g. the Netchillick Eskimos on the Boothia Isthmus, the Ugjulik Eskimos on King Williams Land and the tribes on Coronation Gulf. All hunting on the ice requires however an even surface of ice, so that dog-sledges can be used. Irregular pack-ice frozen in summer, such as is met with along the Ellesmere coast and up through the narrow waters north of Smith Sound, is a hindrance to hunting and sledging, and prevents any per- manent settlement of the Eskimos. The first to point out the vital importance of the winter ice, formed in the course of the winter, for the Eskimo culture was the celebrated American ethnographer Franz Boas of New York! He demonstrated, that it is the nature of the ice which determines the distribution of the Eskimos throughout the greater part of the year, and he showed how the extension of the winter ice depends chiefly on the configuration of the coast, as also on the currents and tides, since a strong cur- rent can prevent the formation of fixed ice. This is the case for example, as already mentioned, in the middle of the North Water, where the current flows out and in through Smith Sound. It is only inside the islands lying in the mouths of the two large indentations that an even winter ice is formed, which has the chance to lie unbroken throughout the greater part of the year. As a rule this is formed in October and lies to the beginning of July, in other words ca. 9 months in the year. In 1903 Knud Rasmussen journeyed with dog-sledges from the east side of Saunders Island to the mainland even so late as July 17th, If it should happen any autumn that the seas is unusu- ally late in becoming frozen over, the hunting suffers, and ! Franz Boas: The Central Eskimo. 6th Annual Report of the Bureau of Ethnology. Washington 1888, p. 417. 274 famine may ensue. Here and there the even surface of the winter ice may be broken by an iceberg or an ice-pack which is firmly fixed in the ice and surrounded by a snow-drive. It happens frequently also that the changing wind may carry a swimming ice-block forwards and backwards and thus a stretch of open water is maintained, from the margins of which the Eskimos can carry on their hunting. Along the coasts a fixed ice-base is formed which is frozen solidly to the land; its surface corresponds with the high-water mark. Outside this ice-base the ice rises and falls with high and low water, and the boundary is formed by а break and sometimes also by washed-up ice-masses. Just above the ice- base, on the fixed land, where the coast is low and has a supply of stones for building material, the Eskimos set up their winter-houses with the low passage and skin windows towards the sea. It sometimes happens that this ice-base remains throughout the summer; thus Kane found an ice-base several years old which was 10 m thick and 40 m broad in Smith Sound. Several things would indicate that the lands round Smith Sound are subject to a regular and slow sinking, in contrast to the rising which is believed to have been noticed along the north coast of North America from Coronation Gulf westwards’. This sinking was already noticed by Kane and was strongly maintained later by Peary. As evidence of the sinking Astrup states, that he has seen remains of houses now under the sur- face of the water on the south-western side of Saunders Island’. Knud Rasmussen narrates that it is the Eskimos’ own view that the land has sunk and that the sea is spreading. At the settle- 1 cited from G.

Whether the ground has sunk before the foundations were carried away, I cannot definitely determine, though it seems most probable. It is not my intention to give here a complete description of the geology of the region dealt with, its climate, animal and plant life. I need only mention the conditions which are of importante for the Eskimo culture, that is, of anthropo- geographical interest. Most of these conditions have already been mentioned and only a few additional remarks need be made. In earlier times the Polar Eskimos obtained materials from the ground for their stone-knives and stone-axes and even on Peary’s and Astrup's first visit these had not quite disappeared. Slate has at any rate been used for such women’s knives (Ulo), which were employed for scraping the blubber on the inner side of seal-skin. As mentioned earlier, Ross narrates that when he met the Polar Eskimos at Cape Yerk in 1818, he found in their possession rude knives and harpoon points with cutting edges of meteoric iron. So far as he conld understand from the explanations of the Eskimos, this iron came from ап “iron- mountain” on Melville Bay, north of Bushnan Island. The place was found in the spring of 1894 by Peary by the help of an Eskimo, who knew both the place where it occurred and also the use of this natural iron, which is really of meteoric origin in contrast to the Disko iron, which was originally deposited in the basalt. Peary thus describes how the Eskimo found the place: ‘‘Kicking aside the snow, he exposed more pieces, saying this was a pile of the stones used in pounding frag- ments from the ‘‘iron-mountain”. He then indicated a spot four or five feet distant as the location of the long-sought 276 object”. The large block of iron was cleared of snow and the Eskimo told Peary, "that the Innuits call the meteorite a woman in a sitting position, and he says it used to be much larger and higher than it is now, but that his people have gradually worn it down, and that years ago natives from Peterahwik (on the coast north of Inglefield Gulf) broke off the head and carried it away. He also voluntarily told how the ancient knives of his people used to be made, namely, by inserting small flattened pieces of the metal in a bone or ivory back, and then with a piece of trap lying near, showed me how the flakes of iron were detached”. In 1895 Peary procured a woman’s knive, which was found in an old winter house at Netschilivik, as also a man’s knive from the old settlement Kangerdlugsuark (Kangerdlooksoah), far in on the south side of Inglefield Gulf, and both instruments were provided with an edge of the natural iron!. This use of the natural iron can scarcely have arisen at the place itself, but is certainly due to some influence from outside. Possibly it came from the more southerly west coast of Greenland over Melville Bay, or it may have been learnt from the use which the Central Eskimos on the North American continent make of the natural copper oc- curring on the islands and coasts at Coronation Gulf. The question cannot be further discussed here; for its solution we require typological studies on archaeological material which is still wanting. Of minerals which are of cultural importance for the Polar Eskimos we also find sulphur pyrites, used for making fire, and soapstone, from which lamps and cooking utensils are made. The principal locality for sulphur pyrites is the so- called “ignerite” hill (fire-stone hill) at Fitz Clarence Rock in Booth Sound. One of the principal soapstone quarries lies on the coast some kilometers west of the Petowik Glacier. + В. Peary: Norhward ete. Vol. II, рр. 145—147, 612—614 (fig. of the two knives). ОТ The lack of trees has been of vital importance for human life on Smith Sound, and in earlier times this lack was even one of the main reasons why they could not build boats. The conditions are different here from those in South Greenland, from Egedesminde and southwards, where the coast received plenty of drift-wood. Extremely little of this occurs so far to the north, even though small quantities certainly drift in fairly regularly. Hall! found a piece of drift-wood which was about { m long as far north as Kennedy Channel, and another some- what shorter piece; and Greely”? gives a list of the drift-wood collected on his expedition, consisting almost entirely of willow, pine and cedar. Attention has only been paid hitherto to the more restricted region of the Polar Eskimos from Cape York to Smith Sound; this is the district where they have their fixed winter dwellings and where they pass all the dark periods, as well as the times of leisure and scarcity of food. The place is well-marked off from natures side. Smith Sound is a little over 50km broad at its narrowest part and in the winter is covered by a solid layer of ice: according to the Eskimos it can be crossed at this time not only by the polar bears, foxes, reindeer and hares, but also by the musk-ox and the polar wolves. In spite of this, the two last-mentioned animals do not occur at Ingle- field Gulf and Wolstenholm Sound. The musk-ox is said never to have been seen south of Cape Alexander; but the Polar Eskimos have been from early times accustomed to cross over Smith Sound and hunt them on the east coast of Ellesmere Land about Bache Peninsula. A few polar wolves are some- times met with at intervals of some years, probably roving animals which have lost their way south of Cape Alexander. The different occurrence of the two kinds of foxes on the 1 Е. Bessels: Die amerikanische Nordpol-Expedition. Leipzig 1879, р. 296. ? А. W. Greely: Report on the Proceedings of the U. $. Expedition to Lady Bay, Grinnell Land. Washington. 1888. Vol. 1, рр. 313 and 534. 278 two sides of the Sound has already been mentioned. And it is also peculiar that the races of reindeer differ in an almost exactly parallel manner. On the east side we find the common Greenland reindeer, which is closely related in all its structure and appearance to the caribou of the North American Barren Ground. On Ellesmere Land, on the other hand, we find a smaller race (Rangifer pearyi Allen), which is also said to differ in colour, form of the horns and anatomical features’. The polar bear has quite a special importance for the Polar Eskimos. It is their most dangerous enemy while hun- ting and it has been in great degree their trainer in hardihood ‚ and ingenuity. Further, there is no Eskimo tribe which requires and uses the skin of the bear for clothing to such an extent, as the Polar Eskimo’s district falls within the region of distribution of the polar bear; but it only occurs in small numbers at the fjords. It is most abundant, on the other hand, up in the Kane Basin at the Humboldt Glacier, as also in Melville Bay off its many ice-streams, and the Polar Eskimos sometimes sledge up to these localities to hunt for the bear and provide themselves with its indispensable skin. The areas visited by the Eskimos thus extend from the Humboldt Glacier right down into Melville Bay. Sometimes they have come so far down that the West Greenland bear hunters have found the traces of their sledges; but, at any rate during the period of the Danish colonisation in the district of Upernivik, there was no connection with the more southern Greenlanders before 1904. According to Knud Rasmussen the Polar Eskimos tell of a bloody conflict they have had with the latter, after which they no longer ventured to go so far to the south. And there is scarcely any doubt that there has been an occasional connection once upon a time, which for some reason was broken off some generations ago, perhaps in the 1 Bull. Amer. Mus. Nat. Hist.

Stein", who made a special investigation of the extent of the original geographical know- ledge of the tribe, came to the result, that it extended so far to the south as even to include Upernivik, whereas to the north it only went a little beyond the more restricted home- district of the race (a little beyond 79° N.L.). it is, in fact, an enormous extent of land and sea which this handful of people, counting little more than 200 indivi- duals, must toil over in order to procure for themselves what is necessary for the maintenance and security of life. Ш is a tract of 6—800 km. Towards the land its extension is of course limited by the inland ice, which for the Eskimo is sur- rounded by superstitious dread and mystery. Journeys over the glaciers are however by no means unknown. It happens, that open water off a projecting promontory must be avoided by driving over the glacier-covered land with the dog-sledges. And two sledge-routes pass over the marginal zone of the inland ice in going to the principal reindeer district in Olriks Fjord. The one goes from the settlement at Netschilivik up towards the most northerly of the glaciers, which open on to Barden Bay, and further in an easterly direction on the inland ice. The other leads from North Star Bay up the valley, which is the eastern continuation of the bay in towards the land, and up on the inland ice; thereafter the route bends in a northerly direction and leads towards the inner part of Olriks Fjord. Both of these glacier-routes are used in the autumn, before the long, river-like Olriks Fjord with its strong current is frozen over, and even before the ice-free foreland is suitable for sledging, so that the baggage must be carried up to the margin of the glacier. - All the wanderings aud journeys of the Eskimos are made by sledge, as the period of open water is so short; and it is В.

A group of islands like the Carey Islands seems never or seldom visited by the Eskimos either by sledge or by boat, though the islands can be seen from the coast of the mainland. On Ellesmere Land the Polar Eskimos had earlier never passed over the relatively narrow tract of land which extends between the indentations on the east coast to Bay Fjord on the west side of Ellesmere Land. Along the east coast they have not gone very far north or south of the indentations on Bache Peninsula. Nowadays, however, this has been altered as the result of the influence of expeditions and the informa- tion gained therefrom, and some Polars Eskimos have already on their own initiative extended their horizon as far as Jones Sound and the west side of Ellesmere Land. III. The state of culture of a tribe can express its primitive- ness and lack of development mainly in two ways. There is in the first place the division of labour; the more undeveloped, the less the division. Every individual of a tribe in the state of low culture does the same kind of work as every other. The most primitive condition of all is, that the individual seeks his food alone for himself without cooperation with others and without giving others help; it is the individualistic mode of life, which however one scarcely finds realised in all its purity in any single case. The second direction in which primitive- ness can display itself in a decisive manner is in the lack of special apparatus and the lack of acquired, skilled methods in obtaining a livelihood. The expression ‘‘collectors” has been employed to denote those tribes, which stand in the lowest stage of development both as regards the individualism as also in the other direction LE mentioned. At the present day true ‘collectors’ hardly exist. as the industrial culture of all known tribes is based on spe- cial acquirements or trained methods in using special apparatus. This applies especially to the male sex, whereas the direct participation of the female sex in obtaining the means of sustenance consists as a rule merely in the collecting of every- thing possible that might be eatable, as fruits, roots, eggs, larvae etc., thus, things which can all be obtained without the use of other apparatus than a pointed stick for digging up roots. We might say, therefore, that among the hunting peoples the woman still remains at the “collector” stage, whilst the man has developed a special and higher form of culture. Amongst the hunting peoples we may therefore with a certain amount of right distinguish between two modes of liveli- hood, namely, hunting, which is pursued by the men with special weapons manipulated in a special, trained manner with sport-like character, and secondly collecting, which is carried on by women, children and old people or all those who do not possess the strength or skill to take part in the hunting. In the culture stage of the pure hunters, therefore, hunting and collecting correspond partly to man’s and woman's work; it is on this basis at any rate, for a very great part, that the often sharp division between the work of man and woman as also between their customs has been founded. It is self-evident, that it would be wrong in a scientific consideration of cultures to distinguish fishing from hunting as а special or separate mode of livelihood. Fishing has to be regarded as “hunting”, if it requires special apparatus in conjunction with special methods of capture or great strength, and in these cases it belongs to the activity of the men. On the other hand, it is merely ‘collecting’, when a wealth of fish is so easily obtainable that women and children can help in its capture. Applying now these considerations to the culture of the Polar Eskimos, we find that this, like that of the remaining Eskimos, stands no higher in the direction of division of labour in the making of their living that most of the other hunting cultures throughout the world. Every man must be a hunter, even the priests or angakoks, and there are no special leaders or organisers in the tribe. On the other hand, their industrial culture stands even very high as regards its wealth of apparatus for various uses and as regards the acquired skill and sportman’s craft and daring with which they are used, even though the apparatus is only for the use of one person, not of many together, i. e. individualism is predominant. 283 We can readily see that the Polar Eskimos have raised themselves high above the level of the “collectors”. Further, we also find that the sport-like hunting plays a more promi- nent part than the simple collection of the means of life; the natural conditions indeed do not give much opportunity for the latter. Berried fruits and eatable insects hardly occur and the beach is practically bare of edible shell-fish. Nevertheless this essentially woman’s mode of livelihood does occur. И appears typically in the case of the few, fresh plant-materials which may be eaten, namely, some sweet-tasting flower-buds and some sourish leaves, which are eaten either raw or after boiling with a little water, and it is as a rule the women and children who enjoy this kind of food. To balance matters the men are able to obtain another kind of plant-food, as they eat the contents found in the stomachs of reindeer; this is a very favourite food and as only the men have access to the reindeer meat stored in the depots, it is specially a man’s dish. Again, the women take part in the catching of the Little Auk, which takes place on the readily accessible, sloping cliffs by means of a large net attached to a 2—3 meter long pole, the hunter lying down among the stones and stretching up the net to catch the birds as they sweep in thousands over his head. On the other hand, the hunting of the Great Auk and the collec- ting of its eggs on the steep sides of the cliffs, where the hunter is let down from above by a rope, is purely man’s work. Similarly it is for the man to fetch the eggs of the eider duck from some small islands, e.g. from Dalrymple Rock. In connection with these conditions we can also note a ten- dency on the man’s part to make the eggs his own particular property and to forbid the women touching this delicacy, which is enjoyed even though the development of the embryo is far advanced”. ! ef. Josephine Diebitsch-Peary: My Arctic Journal. London 1894, pp. 163—164. XXXIV. 19 The Polar Eskimos as well as the Eskimos in general are distinctly nature people, in the sense that their direct depen- dence on and adaptation to the natural conditions under which they live, is distinctly apparent everywhere in the life of the tribe. The varied hunting equipment and the highly developed cleverness in hunting, however, place the Eskimos not among the lowest but among the most developed hunting peoples the world knows. If we divide the hunters into the two cultural categories, lower and higher, we often find the Eskimos placed in the lower class along with the bushmen, the dwarf negroes, the Australian negroes and the Botocudos; but this is by no means right. The Eskimos’ culture-apparatus for the main- tenance and security of life is even specially well-developed and entitles us to place them among the higher hunter peoples. The Polar Eskimos belong to the group of Eskimos for whom the summer and the winter bring very distinctly different modes of livelihood, corresponding to the great changes in the natural conditions. In winter the surface of the water is solid ice and snow, in summer it is over the greater part a rolling sea. We might indeed speak of a summer culture and a winter culture. The summer culture is characterized by the kayak, the kayak hunting and the summer tent, whilst the winter culture is characterized by the dog-sledge, hunting on the ice and the winter-house. For the Polar Eskimos the summer activity is of very brief duration, that of the winter long. As we go southwards along the west coast of Greenland, the summer mode of life becomes more prolonged and the winter mode more restricted. When we come right down to South Greenland, south of the Polar Circle, the dog-sledges and the hunting on the ice quite dis- appear and during the whole year the product of the bunting must be sought for in kayaks on the open sea. Quite a parallel transition is met with along the west coast of Alaska, where the Point Barrow Eskimos mainly pursue the ice-hunting, whilst 285 down towards the Aleutians the sea is open the whole year round and we find a very higly developed kayak-hunting, just as in South Greenland. There can be no doubt that the many points of agreement between the Eskimo culture in South Greenland and that in South Alaska have arisen from this adaptation to the same kind of natural conditions. At both these places the Eskimo culture has become subarctic, whilst in the intermediate, more northerly regions from Point Barrow to Baffin Bay it assumes more distinctly arctic forms’. The Polar Eskimos are thus preeminently arctic people, but in cul- tural regards not appreciably more so than the continental Eskimo tribes from Coronation Gulf to Melville Peninsula. — In addition to the division of the year into a period of 3 months with open water and another of 9 months with ice and sledging, we find here also, owing to the situation so far north of the Polar Circle, a dark period and a light period with two intermediate periods when the sun comes up and goes down. The dark period or the true winter time lasts from about the 15t of November to the 11% of February, ог са. 102 days, in the regions about Cape York or more correctly 76° N.L. Then comes a kind of spring-time with day and night, which lasts till about the 29% of April, after which the sun no longer goes down until the 15 of August, i. e. for about 109 days. Then follows the autumn period from the middle of August to the beginning of November. The further north we go the more do the real dark and light periods in- crease in duration at the expense of the intermediate, arctic spring and autumn; in Inglefield Gulf, for example, these periods are each fully ten days longer than at Cape York. These four polar seasons, which are each approximately one-fourth of the year, determine the yearly changes in the Eskimo life and the yearly hunting journeys, but the part they 1 ef. H. P. Steensby: Om Eskimokulturens Oprindelse. Kobenhavn 1905, pp. 12 and 142 et seq. 19* 286 play is more indirect, in affecting the occurrence of the ani- mals hunted. The winter-houses, which stand empty through the summer and are almost always partially unroofed, are made ready in the course of September for dwelling in and begin to be used as a rule in the latter half of September, after which — excluding journeys — they are dwelt in until May. In setting the house in order both men and women must take part. A family has however no right of possession to a house, longer than they are just resident there, unless it is expressly stated to the other members of the tribe, that they will occupy the same house next winter. Otherwise it can be taken by any one that likes. The fact is, indeed, that the winter is not passed at the same place each year. The family, which one winter has lived at Cape York is perhaps met with next winter at one of the most northern settlements of the tribe. Quite new winter houses are however only built exceptionally, as it is more con- venient to repair one already existing, and such deserted dwel- lings are to be found at various localities along the whole coast right from Bushnan Island to near the Humboldt Glacier. The most southerly houses which are used during the winter lie on the east side of Cape York (75°51’ №. 6.) between the point of the promontory and the nearest glacier. A number of winter-houses are collected here, built into the sloping in- cline at the foot of the high, steep cliffs; the place is called Ivnaganerk by the Eskimos. The northernmost place used has long been Etah or Ita, which lies at Port Foulke at 78°15’ N.L. At the time of Kane’s expedition and again within recent times they have gone right round to Kane Basin to Anoatok or Anoritork, which has become known through being the start- ing-point for Fr. A. Cook’s expedition. The other places most used between these two outermost points are as follows, beginning from the north: Nerkré or as the English and American authors (especially Peary) write it, as 287 a rule, Nerkey, which lies west of Robertson Bay; further, Krana (Engl. Karnah), which is situated on the north side of Inglefield Gulf between Mc Cormick Bay and Bowdoin Bay; Narsark (Engl. Narksami), which lies on the south side of Inglefield Gulf a little to the east of the mouth of Olriks Fjord and which owing to its position is like a centre for the dwellers on the Gulf; Itivdlerk (Engl. Ittiblu) on the south side of the mouth of Olriks Fjord; Netschilivik (Engl. Netchiolumy) on Barden Bay; Kiatark (Engl. Keaté or Kieti) on the south coast of Northumberland Island; Umanark (Engl. North Omenak or Oomunui), which receives its name from a neighbouring, table- shaped mountain on the north side of North Star Bay and has a similar importance for Wolstenholm Sound as Narsark for Inglefield Gulf; Agpat (Engl. Akpan) on the south-west side of Saunders Island; as also the small settlement Igfissork (Engl. Ipsuischo, Ipsueshow), which lies on the small Parker Snow Bay about halfway between Cape Atholl and Cape York. It was at Umanark that the new Danish Mission Station was set up in 1909. The snow-houses are not actually used at any definite period of the year, but only as lodges whilst hunting or on journeys during the winter. These snow-houses, which require suitable, hard, frozen snow, are built by the Eskimos in the course of a very short time, the men with their long snow- knives cutting blocks of snow from the drifts and placing them in a spiral-line above one another, until the whole becomes an arched dome. ‘Towards May, when the snow is less suited for building purposes and the summer tent is already in order, a combination of snow-house and tent is set up on the journeys, a low snow-wall being first built and the tent in a folded con- dition is then laid on the top to serve as roof. Sometimes also, a mere wall is built for shelter or even this is quite omitted and the Eskimos simply lie down and sleep on the snow. Further, natural caves or overarching shelters in the 288 cliffs, several of which occur along the coast, are used both on the sledge and kayak journeys, when the night / £ L р | ET JSÅ . =. / À N À er Е À ; J Fig. 1. has to be A snow-house seen from the side (drawn by the Eskimo woman Alakrasina).

This collection of winter and sum- mer dwellings, hunting lodges and improvised shelters on journeys, which the Eskimos know how to construct, already shows to what a high degree and in what a practical manner they adapt themselves to the prevailing conditions. 1 Peary: Northward etc. Vol. Il, p. 139. = Knud Rasmussen: Nye Mennesker. Kobenhavn 1905, р. 90. 289 This appears just as clearly also in their methods of hunting and journeying at the different seasons of the year. It is only possible naturally to sketch and describe the main fea- tures of these, as there can be some differences from the ordinary routine depending both on geographical conditions as well as on personal conditions and pleasure. The Eskimos are most bound to a definite spot during the summer or more correctly in the months of July, August and September, as they have open water then and their complete lack of large boats for journeys (umiaks) prevents moving. The earlier mentioned, American Eskimos, who immigrated to these parts in the sixties, certainly knew the travelling or women’s boat, and they seem also exceptionally to have used it. Thus Knud Rasmussen! narrates that the Polar Eskimos tell of a group of men, who were isolated during a bad hunting period on Cape Melville in Melville Bay, and that, when the summer came, they made a women’s boat from their tent-skins and rowed away to better hunting places. However this report may be judged from a purely historical standpoint, it bears witness that the Eskimos have not been wholly unacquainted with the idea of large skin-boats. At the present time, when the Eski- mos have had access to wood for some years, it is probably and mostly for practical reasons that they do not build such boats. A umiak, namely, cannot be taken on the sledge, so that in order to have any advantage from it, a family must end its ice and winter life exactly at the same place where, 9 months previously when the sea became frozen over, it began; such a women’s boat is however not so useful during the short summer life, that the Polar Eskimos would willingly bind them- selves in such a way. We find therefore that the few boats, which the Eskimos have in the course of time come into pos- session of from expeditions, have been permitted to lie without being put to any appreciable use for the tribe. aser р. 28. 290 In the old days, before kayaks were obtained, the summer had to be passed on one of the grounds frequented by birds, where life could be maintained at any rate until the ice-hunt- ing began again. The Eskimos are not now so firmly bound . to such localities; what they now seek for are the places where the sea-mammals occur and where at the same time the sea is calm in the shelter behind land and ice-fields. These con- ditions are found inside in Cape York Bay, as also inside the groups of islands at the mouths of Wolstenholm Sound and Inglefield Gulf. At Cape York the white whale (Beluga), nar- whal and seals (bearded seal and fjord seal) are almost the only forms in the summer hunting, whilst at the two other places as also at a third place right up at Etah, the walrus is also present, as it has its summer haunts there at a certain depth of water, where it lives upon the shell-fish of the bottom. It is not the case here as in South Greenland, that the settlements at the open sea are placed on the outer side of the fringe of islands, where the open water is always near and where the hunter can approach nearer the seals when the water is rough than when it is smooth. Nor is the kayak of the Polar Eskimos like the light, elegant boat of the South Greenlander; it is clumsy, heavy and open, the hunter sitting in an open space, whereas in South Greenland he becomes one with his boat by means of a closely fitting fur-skin. The kayak, which has become the main apparatus of the subarctic Eskimos, is of quite subordinate importance among the Polar Eskimos, whose main apparatus is the dog-sledge. The places now preferred by the Polar Eskimos for the months of July, August and September are in the main the same as the winter dwelling-places at Cape York and Etah and those which lie in the mouths of the two large indentations. Some of the principal conditions for a summer settlement are in fact the same as the conditions for setting up their winter dwellings. In both cases they require calm and sheltered 291 water — in the one case for their kayaks, in the other for the even surface of ice. Lastly, the conditions for landing from the water with the kayak and from the ice with the dog-sledge are very much the same, as they both require an even, slop- ing beach. The summer hunting from the kayak however is on the whole not so very important. When the spoil has been killed, it is towed on land, where the sealer himself skins it and places it in the depot, when it is not at once divided up on the spot for distribution at the settlement or among the parti- cipators in the hunt and towing. The distribution takes place according to fixed rules. The first harpooner or the one who first struck the animal has the first right to take certain, spe- cially good pieces; then come the second and third harpooners and then the others taking part. The animal on being cut up is divided into definite portions, the principal of which, accor- ding to a drawing of a walrus accompanied by an explanation which | received from Napsanguark, are the two breast- pieces, the lateral halves of the back, the neck, head, the front flippers, the two lateral halves of the body, the hind limbs, the two rib-pieces, the two stomach-pieces, the two lumbar por- tions, the tail with its root and the liver. The Eskimos have an excellent knowledge of the anatomy of the animals and divide up a walrus with surprising skill and speed. That it is the man among the Polar Eskimos who skins the animals, whereas this is distinctly woman’s work among all the other Greenland Eskimos, finds its simple explanation in this, that the usual spoils for the Polar Eskimos are much larger animals, which cannot be brought home whole to the settlement with the kavak or on the sledge, as is the case with the smaller seals in South Greenland. This appears very distinctly when we consider the Polar Eskimos’ ice-hunting of the walrus, as will be described below. Towards autumn, when the reindeer are fat and come together in herds on the lichen-covered plateaus at Olriks Fjord, a number of families move up there along the routes already mentioned. Whilst the men are hunting the deer, the women and children catch salmon in some few (certainly only 2 or 3) lakes which occur there. These lakes are already covered by ice and the fishing is therefore carried on through holes in the ice by means of an ice-fork. This is one of the instruments which the American immigrants at that time taught the Polar Eskimos. The above mentioned old man, Merkrusark, who himself belonged to the immigrants, gave Mylius Erichsen! the following account of their methods of salmon fishing. “Оп a strong line we fix small pieces of narwhal’s teeth or walrus’ teeth, then drop it into the water and pull it up and down until we catch the salmon, which we land with a two-pronged fork’. The method is well-known at several other Eskimo localities. The fish is eaten either boiled or frozen and is kept in the frozen condition through the winter. After satisfying its lust for hunting and its desire for reindeer flesh and fish, and after storing the excess of food- stuff in the depots, from which they are only fetched when the dark period is over, the family journeys back again to the coast, where the even winter-ice has already as a rule begun to form. Apart from variations in the time for the appearance of the ice-cover, the sledging on the fjord-ice generally begins in October. The intermediate periods between open water and solid ice, which may last a long time during storms, are actu- ally barren periods, when the hunter is compelled to lead an idle life in the winter-houses until the ice becomes solid; often they are periods of famine when the depots are reduced. Then begins the real arctic form of life with hunting on the ice as the main activity. The walrus, white whale and narwhal go out to the ice-free waters and the hunters at the т 1. ©. ‘pp. 307—308. 293 different settlements are accustomed, in the autumn or by moonlight, to go out on sledges to the margin of the ice at the groups of islands in the mouths of the fjords and hunt the walrus on the newly formed ice. Inside the fjords there are only the fjord-seals. These are first hunted when the winter has set in, one of two methods being employed according as the ice is smooth and bare or covered by a layer of snow. When the ice is smooth, the hunting is carried on in the manner known already from Umanaks Fjord in West Greenland, as described by Rink!. In this method the hunter covers his feet with hairy skin and can thus walk noiselessly on the smooth ice, which he cannot do on a rough or snow-covered surface that crackles as he goes along. If the hunter possesses acute hearing, which can distinguish the sound and direction of the breathing seal, and a sharp eye to detect the breathing hole in the ice, he can silently run up and strike the harpoon into the seal, just at the moment when it has sunk its head and is about to leave the hole. In striking at this moment he manages to do so in the neck or in the soft parts behind the head, and not in the harder, more resisting part of the latter, so that the harpoon penetrates deep and remains fast; the seal is thus attached to the line which the hunter holds fast. After some time the seal must come up again to breathe, but is met by the lance and is in the end hauled up on the ice; during the struggle the hole must as a rule be made some- what larger. This smooth-ice hunting can give a considerable yield in the beginning of winter, especially when a large num- ber of hunters take part so that a watch can be set at all the breathing-holes over a large area. Peary” describes it in the first days of November 1894. ‘‘The natives are making’ the most of the new ice in the Sound (i. e. the waters between 1 H. Rink: Grönland, geografisk og statistisk beskrevet. København 1852—57, 'Vol..l. ? Northward ete., Vol. II, рр. 402—403; cf. Knud Rasmussen, I. c., р. 242. 294 Herbert Island and the mainland) before snow comes to cover it and bring the harvest to an end. Every man and boy that can raise a ‘‘pussymut” (seal-spear) is living on the ice night and day, clad in his heaviest furs, his feet muffled with noise- less bearskin pads, and with his little three-legged stool, on which at a pinch he sits for hours, waiting for the unsuspec- ting seal to come to its breathing-hole, and receive the murder- ous spear-thrust. In the afternoon Panikpak returns and tells me he has killed sixteen seals off the Castle Cliffs, and Koolootingwah an equal number. Over a hundred seals had already been killed by the natives of Karnah and Koinisuni, and if the snow holds off a few days longer, it is likely that, in addition to their store of walrus and narwhal meat, there will be two seals apiece for each man, woman and child at _ these settlements.” In general the stool mentioned is not used during the smooth-ice hunting; but it is most probable that in Peary’s case every single breathing-hole has been watched over by a hunter; otherwise the stool is used when the ice is covered by snow, in the true ‘‘Maupok” or ‘waiting’ method. This is carried on over snow-covered ice, when the hunter dare not move from fear of disturbing the seal; he must stand or sit still at the breathing-hole and wait till the seal comes up to breathe, A further difficulty with this method lies in finding the situa- tion of the breathing-holes under the snow-cover. From the Central Eskimo tribes we have the report that they employ a specially trained dog, led on a line, to scent out the holes, and it is probable that the Polar Eskimos know the same mode of procedure!. In this Maupok hunting, however,. a three- legged stool is used, whose ‘‘weak and thin legs composed of many, small pieces of wood are elegantly stiffened by means of thin, diagonally wound thongs”. This is the description 1 ef. L. Mylius Erichsen and Harald Moltke: Grønland. København 1906, p. 524. 295 given by Astrup! of the Maupok stool of the Eskimos. Those I have seen in 1909 quite agree with this, except that the legs now consist of whole pieces of wood or sticks. Fig. 3. Strangers arrive at the winter settlement (drawing by the Eskimo Samik). Above, a snow- house and below this a winter-house, which is only partially drawn. The smoke-hole is seen on both houses. In front of the snow-house a woman is sitting with a child in the “ата”; in front of the winter-house there are also two persons, whilst a third is sitting on a sledge; the upright back at the hind-end of this is supposed to have a hunting-line wound round it. The dogs of the settlement are fastened together in a clump to a stone, but are trying to make towards the people in front of the houses, as they imagine they are about to be fed; but it does not occur to them to make towards the new-comers; Greenland dogs do not watch over the house, but only the sledge when they are harnessed to it. The long, horizontal line in the picture represents the boundary between the land and the sea-ice. The strangers have come half over this line and stopped. One dog does a necessity on the ice; some others seek to settle their personal disputes and cannot be distinguished from one another. The Eskimo man is standing behind the back of the sledge with the whip in his hand, whilst the woman is sitting on the sledge and points towards the fighting dogs. Some time after the sun no longer rises above the hori- zon, it is still light enough to be able to hunt on the ice, but it gradually becomes darker and this puts an end to the 296 hunting. In the course of the 3 months’ winter-darkness there is moonlight three times, and these occasions are used in paying visits to other settlements, or sledge-journeys are made to bring in food from the scattered depots; in cases of neces- sity the Maupok hunting is also carried on at the breathing- holes. Sometimes a wandering polar bear, scenting supplies of food, may rove into the settlement, and in such a case torches are lit and all join in hunting it. But, for the rest, the dark period is a time of feasting, when the Polar Eskimos come together, sing folk-songs and tell one another expansive hunting stories and the latest news. In January 1895 Peary? on a visit to the settlement Krana had the opportunity of participating in such a visiting and feasting period. ‘‘In the evening the village was a scene of feasting. А fetid seal-feed was in progress in Kardah’s igloo; in Akpalisoaho’s a little-auk spread was laid out; and in Ingeropahdoo’s another feasting crowd was gathered about a large walrus-ham, which took up nearly all the floor. Ootoomish and Tellikotinah, and their wives, visitors from the south shore of the Sound, now on a round of social visits, were making calls from igloo to igloo, sampling all the feasts and gathering all the gossip.” From the beginning of February, when the day-light again appears, families from all the settlements between Cape York to Inglefield Gulf start off on the journey up to the coast at Cape Chalon and Cape Alexander, where the open water in the middle of the North Water lies near the land and a hunting lager is set up at places which may vary in different years. In front of the ice-base along the land and just under the bluffs the Eskimo families build their snow-houses with the entrance and gut-skin windows towards the sea-ice. In the latter half of March 1894 Peary? visited the hunting grounds at Cape Chalon (Peterahwik) and found there over 40 snow- 1 Northward etc. Vol. II, pp. 389—390. 2 ibid. р. 419 et seq. houses, which held more than */srds of the whole tribe. The open North Water lay about 20 to 50 km, west or south-west of the settlement, ‘‘and its edge shifts like the fringe of a waving curtain. Two or three days of heavy wind will eat into the ice and bring the water several miles nearer the shore. Then during the following calm, the fierce temperatures of February and March, the lowest of the year, bind the motionless water with a zone of young ice, which in twenty-four hours will support a sledge and team of dogs. Then is the hunter s time; leaving the village at earliest daybreak he drives out to the edge of the old ice where the dogs are fastened, and then on foot with his harpoon, line and lance, he starts out upon the black mirror of the new ice”. It is important for the hunter to be able to reckon where the walrus will rise to breathe. Usually he waits for it at a hole already formed in the ice, but sometimes the animal comes up at a new place, breaking through the ice. The hunter then hastens guickly to the spot with the harpoon in the right hand and the ca. 40 meter long line of seal-skin in the left. The harpoon is not thrown, owing to the thickness of the walrus hide, but is thrust in, and the pole hastily with- drawn. The spike — formerly of bone, now usually of iron — which is at the end of the pole and has served as base for the loose point of the harpoon, is now planted in the ice, the line is given a turn as far down as possible and the knee and shoulder are brought strongly to bear as counterpoise. When the line again slackens, it is fastened as quickly as possible through two holes in the ice, and the animal as it reappears is met with the lance of the hunter and his comrades, who have hastened to his help. When the animal is dead, it is lifted right up by a kind of tackle, formed by lines of seal’s skin passed through two holes in the ice and a couple of holes cut in the skin, and as the heavy animal, which may weigh up to 1000 kg, is gradually lifted up over the water, pieces are 298 cut off and the whole booty finally driven in the dog-sledges to the coast. At the same time as the walrus hunling is going on, foxes and hares are caught in amongst the coastal hills. The skin of these animals is good and fit for use at this time of year, and it is specially for the sake of the skin that they are hunted. The foxes are nowadays taken in the modern American fox- traps, but we still find everywhere the remains of the old stone-traps. These consist of a small stone-box built of flat stones on the surface of the ground; this is closed at one end and just so long and so high that a fox can crawl into it, at- tracted by a piece of blubber. This blubber is, however, con- nected by means of a thong with a large, flat stone, which falls down and closes the trap, as soon as the fox seizes hold of the blubber. The hares are caught in running nooses, the arrangement and make-up of which will be described later. Towards the middle of April breaks occur in the ice at several places nearer to the land, and the walrus are scattered along the coast. The Eskimos again disperse, going as a rule to various settlements in the outer parts of the fjords; at the same time they keep to the bird-grounds, which are taken possession of by the birds about the middle of May. One group, for example, goes to Agpat or Saunders Island and remains there hunting the walrus, seals and narwhal, and later bird- catching, until the end of June; then just before the ice breaks up they move in on the mainland to the settlement Umanark at North Star Bay, where they pass the summer. Others set up their snow-huts in the neighbourhood of Kiatark and go later to one of the mainland settlements in the mouth of the Inglefield Gulf; others pass the spring on the north side of Inglefield Gulf. During the spring hunting two characteristic methods of hunting the seal are used. The one depends on the fact, that the mother-seal, when calving, digs a hole in under the snow, 299 as a rule in a snow-drift close by an ice-field. From the hole a large opening leads down through the ice, through which the mother passes up and down, and there is a smaller opening up through the snow-drift for the passage of air. A sharp eye can detect these ‘‘seal-igloos” from outside; the Eskimo walks softly up to it, and puts his ear close to the snow and listens. If he hears any sign of life he jumps on the mound as hard as he can, until it caves in, and then, with a kick in the head, he dispatches the young one. If the mother is pre- sent, he seeks first of all to plant the harpoon into her; if she is away, he patiently awaits her reappearance up through the hole in the ice, and then she meets the harpoon. The second method is the likewise well-known Utok hunt- ing, or the hunting of the seals when they lie and sun them- selves on the surface of the ice. The Eskimo approaches his watchful prey crawling on his stomach; at the present day he uses fire-arms, but unlike the Eskimos in the more southern parts of Greenland he does not have a small sledge with out- stretched, white linen sail, behind which the hunter is able to conceal himself. In earlier days it was necessary to approach his unsuspecting prey so closely that he was able to stick a harpoon into it. The method then was, to crawl up against the wind and as far as possible imitate the movements of the seal, lifting the head in the same manner, flapping the arms just like the seal with its flippers and moving the legs as the seal does the tail-end of its body. It is quite an art, which the older Eskimos have all practised and can still practise, but it is dying out in the younger generation. In the latter half of this period, as a rule from the first half of May, the Eskimos dwell in tents, as the snow-houses become damp and wet. The sun is now above the horizon during the whole twenty-fours hours. The Auks and Little Auks have come and taken possession of the sides of the cliffs. There is now abundance of food and it is a time of enjoyment XXXIV. 20 300 for the Eskimos. During this period “there is no regular sleep in an Eskimo camp; day and night are spent abroad when the weather is good. A constantly burning fire summons the people together at the public feeding-places of the camp, and the constant interchange of men going to the hunt and others returning maintains life and interest round about the fire at all times of the day and night”! The bird-hunting is carried on late in May and in the course of June, and stores of birds are laid in, which entire and with the feathers on are laid in blubber in a seal-skin, also eggs, which are kept under small stone-heaps. In the old days the whole summer had to be passed on one or other of the birds-grounds, and these localities are still places of resort for one or other poor and incapable family or for women, who for some reason have lost their providers. In this systematic review of the changes which take place with the seasons in the industrial culture of the Polar Eskimos, some interesting and important features of their hunting-life have not yet been described, for the reason that they are not of regular occurrence each year for all the hunters. These are especially the hunting of the polar bear and musk-ox. The places frequented for the polar bear hunting are Mel- ville Bay and Kane Basin at the Humboldt Glacier. The great extent of these hunting journeys to the southwards has already been mentioned. The season at which they are undertaken is the polar spring. Any one who intends to go bear hunting must make his preparations already in the previous year, in so far as he must obtain several dogs and train them specially to face the bears. The hunting itself requires the dog-sledges, the track of a bear being followed until the bear is sighted; the dogs are then let loose and surround the fleeing bear, keeping it back until the hunter can come up with it. 1 Knud Rasmussen, L. с. р. 46. “poods nF ye Surgoeordde pue {eme aoyjıny aq 04 posoddns st oSpays Jomo oy, ‘oueq ® yuasaıdaı 0} pasoddus st yom ‘ainsg эЗле| Алэл в имелр sey IsıLıe oY} Joddn oy} рищея ‘'598рэ[з g Jo лор og} ur djoug sogoeordde apis 1489 ay} woag ‘лево ay} Aq пу uooq sey 84/5 uostod ay} js11e oY} JO uoreuerdxe oy} 0} Зитрлороу ‘ле ou} poddozs pue pepunoxms элец ssop 9 "41047 OWL sa лерод ey} Aq umeap ‘Surjuny avog ‘+ SU = wee nena 302 At the present time the rifle is the weapon used, but previ- ously it was the lance. Bow and arrow could not possibly be used, as the arrows cannot wound the animal sufficiently, owing to its thick hide and fur. The hunting thus developed into a fight at close quarters with the bear, in which the hunter not rarely received some hard knocks. Some of the Eskimos | saw, especially Masaitsiak and Samik, bore frightful scars on their bodies as the result of wounds from the claws of the bears. The hunting of the musk-ox on the east coast of Elles- mere Land is even more occasional. How this hunting was carried on before the advent of the rifle, has not been clearly explained. But it was even more impossible than in the bear- hunting to employ the bow and arrow against the dense cover- ing of thick, wooly hair of the musk-ox. We are not aware whether the Polar Eskimos knew or employed the lassoo or not, but it would seem practically impossible to catch a musk- ox in this manner, owing to the shape of the fore-part of the body, with the head sloping forwards from the neck and its thick horns likewise projecting downwards and forwards. There can hardly be talk of any other weapon but the lance, and presumably the method of hunting has been almost the same as that employed by Cook and his two Eskimos whilst wintering at Cape Sparbo in 1908—09, when they enclosed or drove the musk-ox on to ground covered by nothing but stones. On such a ground two legs are better than four and the hunter can approach quite near to the awkward musk-ox and easily evade its fury; in hunting these, dogs are also probably used. Both the bear and the musk-ox hunting are old among ihe Polar Eskimos. This does not hold good, however, for the reindeer hunting, which was first introduced by the immigrants from the American side. A contributory reason, why they had not previously troubled themselves about the profitable autumn hunting of the reindeer in Olriks Fjord, may have been that 303 they always passed the summer on the bird-grounds, and thus lived far from just those settlements, such as Umanark, Net- schilivik, Itivdlerk and Narsark, from which there is access to these hunting grounds over the inland ice. Until the time when Peary began his expeditions, the bow and arrow were the main weapons in hunting the reindeer. The Polar Eski- mos became all at once keen deer-hunters and they seem to have rapidly become just as expert and untiring in the hunt Fig. 5. Musk-ox hunting, drawn by the Eskimo Samik. According to his own explanation the one individual has “fallen on the stones’. The other hunter (supposed to be Samik him- self) attacks the first musk-ox, seeking to wound the animal in the heart with the lance (or gun ?). as Other Eskimo tribes. The long, converging rows of stakes, between which the herds of deer are driven into an ambush and which are so common among the other Eskimos, do not seem to have been used by the Polar Eskimos. One of their hunting methods and the most primitive meant simply finding a trail and following it at a steady run, until the animal was approa- ched so near that it could be struck by an arrow. With re- gard to other methods, the Eskimo Imerarsuk told the following to Knud Rasmussen, and I obtained a similar description from the old angakok Masaitsiak. ‘‘The deer at that time followed 304 certain passes between the hills. We can still see up there (i.e. on the hills at Olriks Fjord) the many hard-trodden paths. The hunters knew!, therefore, which paths the animals would follow, both in going down to the coast in the spring and in returning to the hills in winter. They stretched long lines of seal-hide across the deer paths, fixing the lines at short inter- vals to small piles of stones which they built. When a herd of deer came along and ran their heads against the line, they never tried to jump over it but simply followed it along to one of the ends. Here an archer was posted at both sides, sitting within a sheltering wall of stone, so that the deer should not suspect anything, and in this way the spoil was led to the hunter. The custom was also for many to join in the hunt and confuse the herds by cries, so that the deer were driven from the one shooting-box to the other. But for this method to succeed, the ground had not to be too Бгоа4” 1. Fishing is of little importance for the Polar Eskimos. The sea is not so rich in fish as further south. The salmon-fishing of recent years has already been mentioned. Further, I have seen sea-scorpions (Cottus) taken by a boy from his fathers kayak with hook and line, and also a special kind of fishing- apparatus, consisting of a ca. 8 cm long two-pronged fork, with teeth on the inner side of the prongs, which was cut out of a piece of narwhal or walrus bone and attached to a pole quite 1m long. This apparatus was said to be used in fishing for a small fish, probably a gadoid. The considerable booty, the Polar Eskimo obtains as a rule on his hunting tours, cannot possibly be taken along with him to the settlement on his sledge, and still less in his kayak. What he does, therefore, is to hide the surplus in a depot, from which it can be fetched later. The natural conditions during the greater part of the year make this method of pre- serving easy, as the meat freezes, and if the seal or walrus 1 Knud Rasmussen, 1. с., р. 97. 305 flesh does become somewhat putrid, this does not matter so much, as the Eskimos rather prefer the flesh when it is “high”. Seals are even laid out in the spring so that they should become high, and are eaten later as a delicacy. On freezing at the low temperature the meat gradually undergoes a change, so that it becomes soft; when it is then warmed up to one or two degrees below freezing-point it forms quite a nice dish. Pemmican is not prepared as among the North American Indians, but it is a general thing to place birds and the skin of the white whale and narwhal in blubber. The many scattered depots lighten the long journeys for the Eskimos to a considerable extent, the depots being regarded as a kind of common feeding-places. This is one of the rea- sons why they are able to make their sledge-journeys of many miles in length with extremely little baggage and almost without provisions. But the depots also have other obvious advantages ; for example, in keeping their riches out of sight. If the whole of the booty were brought to the settlement, ,the less fortu- nate and the less capable hunters with their families would share in the eating, so long as the food jlasted, instead of going out themselves to hunt. Further, the depots far from the settlements mean several good places for the fox-traps, as the foxes always gather round the depots. IV: The small North Star Bay on the south side of Wolsten- holm Sound is separated from the main fjord by a small peninsula, lying chiefly in the direction from east to west. Furthest west this peninsula ends in a characteristic hill, which has the form of a broken cone with evenly sloping sides and a horizontal level on the top of no small extent. This hill, which is quite 200m high, is called by the Eskimos Umanark _ (Umanak), a name which is commonly used all over Greenland for such isolated, projecting mountains; the word is derived from umat, heart, and would thus mean heart-shaped. To the north-east of Umanark, but on the north-west side of the small peninsula towards Wolstenholm Sound, lies the settlement Umanark. It consists of some groups of winter- houses, which lie scattered along the coast at intervals of some few hundred meters. The most southerly group, which is composed of 5 houses, seems to be the one most used at the present time. In the summer time all the houses lay more or less open, the skins were entirely or partially out of the win- dows in all and in most the roof had been partially pulled down. Further there were empty houses which had not been used in recent years and also others which were so old, broken down and overgrown with grass, that it was only from the cir- cular elevation with the depression in the middle, that one could conclude, a winter-hut had formerly been there. It was evident that stones had been removed from these old places to be used in building the new houses. 307 A peculiar thing was, that some of the oldest ruins were considerably larger than the houses now used, and had a more square-shaped ground-plan. How far these large houses belong to a definite period in the earlier history of the Polar Eskimos, or whether they have perhaps been built by quite a different tribe of Eskimos, which has lived there previous to the present tribe, it is difficult to determine. I thought of something intermediate, that they were perhaps meeting-houses (kashims) of a similar character to those met with among the Central Eskimos on the mainland and among the Western Eskimos, and the Polar Eskimos are certainly not unacquainted with the custom, for those of a certain age to meet together in a common house. Thus, we sometimes find at their settlements a special meeting-house for the young people. For this pur- pose, however, one of the ordinary winter-houses is used, a special house’ of a larger type is not built. This would also be practically impossible, as the Polar Eskimos, with their present materials of nothing but stones and grass-turf and with their modest technical appliances, have probably reached the approximate limit for the size of their houses. On the other hand, there is no doubt, that if the materials permitted it, they would sometimes built larger houses than they now do. These considerations lead us therefore on to a different line with regard to the question of the large ruins. On Baffin Land the natives at Ponds Inlet build fairly large houses, in which the roof is not a stone-arch, but is formed from wood or from whale-ribs, which those taking part in the Scottish whale-fishing still have the opportunity to obtain. Some few centuries ago, when the large whales occurred in great num- bers, it must have been easy for the Polar Eskimos to procure such bones for building materials, from the whales that were stranded or driven on land, and thus to make their houses somewhat larger than they can build them now. For the rest, well-preserved ruins of such houses with cross-beams of whale- 308 ribs still occur at long-deserted settlements!; but unfortunately we have no information regarding the size of these ruins. For the sake of completeness it may be added, with regard to these large ruins at Umanark, that the Polar Eskimos have taken note of them and that they believe, they belong to an ancient period of adventure, when ‘‘people might wish them- selves somewhere else”. If there is anything in this of import- ance for the solution of the question, it is of a purely negative character, namely, that the Polar Eskimos do not ascribe these ruins to any other tribe. Nor is it in opposition to my sup- position, that they were merely the forerunners of the present- day houses, built of material more adaptable to larger houses, which has now been used up. Fig. 6. Part of a hare-barrier, consisting of 3 stone-heaps. Between the two left portions the nooses are represented, between the two right a row of small stones. One of the modern houses at Umanark lay quite uninha- bited with tumbled-down roof. The reason was, that it con- tained a corpse. When any one dies in a house, winter-house or tent, it is forsaken, and a long time passes before such a deserted house is again taken into use. Up from the settle- ments about a couple of hundred meters from the shore there were several old and more recent graves at a place with numerous stone-boulders, but all had been disturbed, most probably by foxes — if not by dogs — as also by the earlier expeditions. At one of these lay the remains of implements; it was the grave of a man, to judge from the remains of a kayak. Even the skeletons and skulls had almost all been re- moved from the graves. These consisted of stone-work above 1 Knud Rasmussen, 1. с., p.85. — cf. В. Peary, Northward etc., р. 380. 309 the ground or between the boulders on the cliff with a rect- angular ground-plan, which was just so long and broad, that the body could lie in a bent-up position, with the knees up against the breast. The grave-implements lay, not in the grave itself, but at the side, and from a distance the grave looked like an ordinary heap of stones. Round about among the cliffs along the coast we here and there find piles of stones in an opening in the cliffs or be- tween a pair of large stone-boulders; these somewhat resemble graves but are in reality food-depots. The principle with these is, that the stones must be so large and heavy that the foxes and dogs cannot push them aside. When we therefore find a cleft or hollow in a cliff, which might readily be covered over, we will also regularly find that it has been used as food-depot and not for a grave. Among the Polar Eskimos the interests of the living are placed before those of the dead. Practically ‘speaking it is certainly impossible to make the depots secure against the bears, so that it is fortunate that these animals are not numerous in the more restricted hunting grounds of the Polar Eskimos. Scattered round about the neighbourhood of the settlement and at the depots along the coast we found al- most everywhere more or less well-preserved, stone fox-traps. Down on the coastal plains around the old and more re- cent groups of houses at Umanark we find a very luxuriant grass-vegetation in the summer-time, which has apparently a very alluring influence on the hares in the winter and spring. About half a kilometer from the coast the last outposts of these grass-oases form some swampy, low-lying places with less vegetation, which lie in the direction from west to east and are bounded on the north and south sides by irregular, stony ground, whilst on the east they change over into more gravelly ground. On the east side of these depressions are constructed one or in a single case two concentric half-circles of small stone-heaps or oblong stones raised on end. 310 One of these semicircles of hare-barriers was quite 45 m long, another 80 m long and the longest I saw had a length of ca. 160m. The single stones or stone-heaps are placed at a distance of 2'/2—5 m from one another and their height is in general 30—45 cm. Sometimes, but by no means always, Fig. 7. View from the settlement Umanark. On the left a depot-pillar. On the right of this a winter-house, seen from the side; on the right of the picture a second house, seen straight in front with the opening to the passage below and the opening of the window above. The beach is immediately to the left of the depot-pillar. rows of small stones, the meaning of which is not quite clear, are placed between these large stones. Horizontal strings of seal’s hide can be stretched between the stone-heaps with rows of running nooses hanging down from them. When a hare comes down from the hills and seeks its way to the grass- covered hollow or is returning from this to the hilis, it runs up against these strings and nooses and begins to play with them or to investigate them somewhat closely. The result in 311 many cases is, that it gets its head or a paw into a noose and cannot free itself. As a rule these hare-traps are looked after by the old men and the larger boys. It is in the polar winter by moonlight and in the polar spring, while the hare- skin is still usable, that this hunting is carried on. A trap for hares, consisting of two converging rows of stones, was seen by me 3—4 km east of the settlement up in the hills; it was constructed in front of a greenish transverse hollow on a small ridge. About two km east of the settlement Umanark, on the north side of the small peninsula, where this joins on to the mainland, projects a small, low point out into the bay. On this is situated a fairly well-preserved ruin of a house, and in front of this there is a couple of half-fallen stone-pillars, which have been used as a place of deposit for food. Two similar depot-pillars occur at Umanark, where they also lie in, front of the houses, so that they can be seen from the passage and window of the house. They are circular, massive and built up of fairly large stones, which are laid above one an- other without any cementing material; the old blubber dropping down from above helps however to bind the stones together. The pillar has steep sides and a flat or slightly concave upper surface, where the meat is laid. The height is judged, so that the dogs should not be able to reach up to the food. The one depot-pillar (to the left in figure 7) is 1,6 m high and ca. 1,2m in diameter of cross-section. The other is of about the same height but a trifle broader. The winter-house of the Polar Eskimo is an extremely interesting production of the small tribe and requires very spe- cial attention. Seen from the outside it is an arched elevation on the ground; a very excellent comparison of its form has been made with that of a large turtle, with its head and neck projecting forwards. The house itself has something of the characteristic arching of the turtle-shell, and the low entrance- 312 passage might well be compared with the neck. Figs. 8, 9 and 10 show respectively the ground-plan, longitudinal section and cross-section of a typical Polar Eskimo house. Fig. 8. Ground-plan of a winter-house. Only the inner part of the entrance-passage is shown at A. The ground-plan gives the front-part of the house, the passage, and the circumference of the house itself. The pas- sage A is closed above at В, which represents the oblong, flat slab of slate which lies right across the entrance and separates this from the window, forming at the same time the lower border of the latter. The passage is thus continued under 313 this slab and opens into the room of the house between B and C through an oblong, approximately rectangular opening, which is shaded in the figure (on the longitudinal section, fig. -it lies between с and 4). D indicates the floor-place of the house, which is surroun- ded on the 3 sides by plat- forms. The principal platform GLH M takes up the whole of the circular space at the back, while the side-platforms Е and УК occupy the two smaller, round spaces at the sides. On the side-platforms are placed the two blubber- lamps F and F’ with the less convex side towards the main Fig. 9. Longitudinal section of winter house, ab passage; cd entrance-opening; m floor; п open space under the main platform ef. 2 platform, where the house- mothers, who have to look after the lamps, have their seats at L and M. Each house is occupied by at most two families. The principal LLY platform is the living-room of the family during the day ‚ and the sleeping-place at night, Nj N whilst the side-platforms are N kept for the lamps and other | WW Comat articles of the house, as also ПГУ, food, and are only exception- ally used as sleeping-place for the children. Above the blubber lamp hangs the cooking-pot, which is suspended by strings from a horizontal drying-board which again hangs on lines fastened to the roof. 314 The reason why the two recesses for the side- platforms E and УК appear so prominent in the interior of the house, is that the walls of the house at Z and M are specially heavy and built somewhat inwards, in order to bear the upper structure and the roof. For the Polar Eskimos have had the most difficult task in forming a support for the heavy roof of stone and earth, as they have had no wood at their disposal and no longer, at least in recent centuries, have access to the large whale-bones, which elsewhere form such an excellent building - material. With regard to the manner in which they have solved this problem, Peary, who was an engineer originally, remarks that MD ED EIER LL 2, 9422274 u LL Fig. 10. Cross-section of winter-house. it corresponds to the modern cantilever-system in engineering, which has been used chiefly in the building of bridges. This original building-method of the Polar Eskimos is illustrated in fig. 10, which represents a cross-section through the house at LM (fig. 8), i.e. through the thickest parts of the wall and across the front part of the main platform. The figure shows, how a long stone on each side is fixed at its base in the wall by means of other stones which act as counterpoise, and how the free, inner ends of these projecting stones sup- port a long and flat, central stone. I have seen several of these top-stones of slate, which were about 1 m long, over ‘/2 m broad and some few ст thick. A third projecting stone is placed further back in the middle line of the house (at f in fig. 9), and there may also be a couple of these, as a rule 315 smaller, intermediate between the three mentioned, as also a further pair at each of the side-platforms. The position of all these projecting stones is schema- tically represented on fig. 11. They enable us to understand the developmental history of the house, as their situation in pairs would indicate, that they must have arisen from a method of building in which there were entire cross-beams going right across the house. We can therefore imagine one of two things. Either small houses were built originally, so that a single stone could: reach across, or other materials besides stone have been at the disposal of the builders. Of these two alter- natives we can certainly exclude the first; houses of this kind would be extremely small, and we have no evidence from anywhere that they have existed. On the other hand, as SS | EAN already mentioned, Fig. 11 DE ы it 15 permissible to Diagram showing the position of the projecting stones in believe, that the Po- Sania whe lar Eskimos have had other building-materials, for example, whale-bones. And it therefore seems reasonable to set up the hypothesis, that at the places in the Polar Eskimos house, where we now find the projecting stones, there have originally been whale-ribs for the support of the roof. The house of whale-bone has thus not only preceded in time the present stone-house, but it has also been its technical precursor. The longitudinal section fig. 9 shows on the left the house- passage, which is formed of two vertical stone-walls with flat flag-stones above, and furthest to the right the continuation of the natural slope of the ground, out of which the house is to some extent dug. The passage is so low that one must crawl on going through it, or like the Eskimos bend the body at XXXIV. 21 316 right angles to the legs; it slopes evenly outwards from 5 to a. In winter it is sometimes further prolonged by means of an arch of snow with the entrance on the one side, or a snow wall is simply raised to serve as a screen against the wind. The normal length of the passage is ca. 3m; its height inside is 60—75 cm and its breadth 60—70cm. At the inner end of the passage a sloping entrance between c and d leads up into the house-room. The opening here is so small, that a well- developed Eskimo must have the greatest difficulty in crawling up through it. It is fairly rectangular and measures in a longitudinal direction, transversely to the house, ‘/2—*/4 m, whilst its breadth (from с to 4) is only about 35—40 cm. This entrance-opening stands as a rule unclosed; but sometimes a stone is placed over it to prevent the dogs from coming into the house, or if the wind is very strong and is blowing right in. The Eskimo creeps tbrough the entrance into the house and is then on the floor of the room itself (m in fig. 9), which is laid with flat flag-stones. The window with its pane of gut-skin looks out on the roof of the passage; its opening is completed above and below by long, narrow pieces of slate, and at the sides by walls of heaped-up stones. The square pane of gut-skin, which is represented on fig. 9 by the dotted line at 7, is sewed tightly by means of tendons on to a skin, in the centre of which a square opening of the size of the gut-skin has been cut; this skin is indicated on the figure by the thickened line at А and 7. The mode of fixing is, to place the lower part of the skin at & outwards on the top- stones of the entrance, securing it there by laying over it a layer of earth and grass-turf. At the sides of the window the skin is likewise made fast out under the covering of earth, whilst at the top it is bent back over the top-stone of the window and in under the earth and stone-covering of the roof. In this way quite an air-tight and solid window-frame of skin is obtained. The opening of the window is ca. 80cm high and 317 70cm. broad. Only a dull light comes through the gut-skin; to be able to see out from the house there is a small peep- hole in the centre. The floor-place itself is not large. Its extent depends partly on the size of the house, partly on the amount of space occupied by the side-platforms. In one house, for example, Fig. 12: Photograph of a winter-house seen directly in front. Uppermost the remains of the window opening and just under this the entrance from the passage. The two openings to the right and left of this lead merely into store-rooms, which are built at the side of the passage. In front of the house the ground is covered with refuse. The beach is just in front. the distance from the entrance to the main platform was 170 cm and across from the one side-platform to the other likewise 170 cm; each of the latter was here only ca. 35 ст broad. The whole breadth of the house in front, including these re- cesses, was thus 240 cm. In another house the corresponding dimensions of the floor were 130 and 175 cm; here the plat- form to the left was 75 cm broad and that to the right as 2 318 much as 140 cm broad, the measurements being taken along the middle line of the side-platforms (ЕК on fig. 8). The whole breadth of the house was thus 39 m. The principal platform in this house was as much as 205 cm long (from e to f) and had in front a breadth of 210 cm; its height above the floor was 30—35 cm in front (at e in fig. 9). The principal platform always slopes evenly down towards the back and the height of the side-platforms is normally the same as that of the main platform in front. Both the main and the side-plat- forms are formed of flat stones, which rest on stones set up on end. In the back part of the main platform, however, the stones lie directly on the ground. Among the piled-up stones of the house-walls we not rarely find, forming part and parcel of the walls, the vertebrae and smaller bones of the large, now extinct or rare whales. The skulls of walrus are also used for this purpose. Some of the stones are so large that one can hardly understand, how it was possible to move them. Pieces of pine or bone are fixed in among the stones of the roof and between these strings are hung, on which small articles of clothing and other objects can be suspended. In the front part of the roof there is a small and narrow opening (at h) which can be closed above by a clod of grass; this is called “позе” of the house by the Eskimos, and in the still winter-frost the hot air can be seen streaming out like white steam. At one place in Umanark two houses had been built together, so that they had a common wall but were other- wise quite like two houses. On fig. 9 we can also see the top- stone g between the two central projecting stones; this helps to supports the flag-stones of the roof. Over these lies the layer of earth and grass-clods 0, and this is again covered by a layer of stones (p). The height of the house internally is not very considerable. I have measured one house (the last of the two above-men- 319 tioned), in which the greatest height above the floor was 145 cm (at m); possibly, however, the roof had sunk a little Fig. 13. Photograph of the interior of a winter-house, from which the front part of the roof has been removed, so that the light falls on the main platform. The photo- graph was taken from the window-sill (to the right of B in fig. 8) and includes nearly the section СЁН on fig.8. Below is seen the platform, composed of a thin slab supported by blocks of stones. The projecting oblique stone seen on the left above is not very large in this case, but to. make up for it the thin slab, which forms the middle part of the roof, over the platform, is very large. On the back wall of the house hang two coils of leather rope, made from walrus skin; a similar coil lies on the platform. in the summer, so that the height might really have been a little greater, but it can hardly have exceeded 160 cm in any case, so 320 that a man of average height will not be able to stand upright in it. In all the other houses the front part of the roof just over the threshold had been removed for the sake of ventila- tion. In this house the greatest height at the front part of the platform was 95 cm, usually it will be about I m in the centre and a little lower at the sides. In the typical house of the Polar Eskimos the whole roof is built up of stone-flags, and this is always the case with the ’ part which arches over the main platform. Оп the other hand, it is not rare for the front part of the roof, just over the floor, to be covered simply by skin, which is spread out over cross-poles and covered outside by earth and stones. At Cape York I saw a couple of houses of this kind, where the remains of the covering skin still lay on the top of the house-wall. In winter the interior walls and roof of the house are covered with seal-skin, the hairy side being turned towards the wall and the light-coloured inside out towards the room. The flat, stony floor of the main platform is covered with a layer of dry grass and above this are laid the skins of reindeer or bear. Each member of the house has a definite place for sit- ting and lying on the platform, counting from the front to the back. He either sits, as a rule with crossed legs, in front on the platform, or lies on this with the head always towards the open room, so that the head is always highest. The place of the wife is outermost at the wall of the house close to the side-platform, the lamp on which she must constantly be look- ing after. Usually, in addition to the two large lamps on the side-platforms, there is also quite a small, third lamp on the one platform; so far аз I could gather, its flame is nourished by the blubber which drips down from the large lamp and is collected in a special holder below this. The blubber-lamps, in addition to warming up the house, give a very pleasant and clear light. One problem in the polar house-building, which the Polar 321 Eskimos have in common with practically all other Eskimos, is to protect the dwelling-room against the wind and draughts, or to obtain, without at the same time interfering with the renewal of the air, a constant supply of the latter which can be evenly and regularly warmed. This is attained in the first place by the long, narrow passage, which stops the spread of the air-pressure and causes it to become an even and quiet stream of air, when it passes into the house, secondly, by the low-lying position of the entrance to the passage and lastly, by placing the lamps on a raised stand and not on the floor itself. As the result of the two last-mentioned conditions, the cold air is able to spread quietly along the floor. It is only when it comes to the level of the platform that it is evenly warmed up by the lamps and gradually rises, so that there is always a warmer layer of air lying above. The products of combustion can escape outwards, partly through the ‘‘nose” of the house, partly through the peep-hole in the pane of gut-skin. The arrangement of the long, low passage, which opens into the house so low down, is thus in reality a kind of equi- valent for the door and porch or lobby, by the help of which the Europeans in cold lands keep the cold air from penetrating directly into their dwelling-rooms. In the eskimo house it is in reality the raised platform, which corresponds to the true dwelling-room. And so cleverly therefore is this house built, that the fresh air has the most unhindered entrance and yet one is in the midst of an even warmth. The Danish painter, Grev Harald Moltke’, who passed a great part of the winter of 1903—04 in a winter-house of the Polar Eskimos, has expressed his opinion on it as follows: “Two things are surprising in this small, primitive hole — the temperature and the good air. The cold air streams through the passage, the entrance-hole and out over the floor, where 1 Mylius Erichsen og Moltke: Grønland, р. 589. 322 the temperature in winter is always below freezing-point, as a rule from —10° to —20°C., so that the blocks of snow in- tended for drinking-water can lie there without melting. The lamps draw the air upwards, which is thus warmed and streams out over the raised platform, where the temperature as a rule is so high, that one cannot stand having clothes on and quickly follows the example of the Eskimos and takes them all off. Under the roof the air is, to put it plainly, very hot. If we sit on the edge of the platform with the feet resting on the floor, they will be surrounded by air at ca. —10°, whilst the head reaches up into a tropical temperature. Only the stomach is in a suitable and pleasant warmth, which explains why no other position can be maintained for a long time in here except lying down on the raised platform. However warm it may become here, the air is nevertheless always pure and good, and — in contrast to the atmosphere in many Danish- Greenland houses — without smell. This is quite simply ex- plained by the fact, that the fresh air always has unhindered access to the house through the entrance-hole, where there is no door’. In contrast to which we now find a door in the Danish-Eskimo houses, which as a rule closes the passage inwards. Figs. 14 and 15 are two drawings by the eskimo woman Alakrasina. The first represents the interior of the ordinary winter-house with a main platform and two side-platforms, as also the passage to the house and the outside structures in front. On each of the side-platforms stands a large blubber- lamp and at the side of this to the left a small lamp; a couple of basins also stand on each of the side-platforms. Fig. 15 is of very great interest. Among a number of winter-houses, which Alakrasina drew of her own accord in my drawing-book, were two of this type, though I found no re- presentative of them, either at Umanark or at Cape York. We see here two winter-houses built together, so that they have a 323 common floor-place and common passage; further, the two adjacent side-platforms have likewise been joined to form a и: LTD Gar.

The important thing about this house-type is, that it shows us in quite a convincing manner, how the long winter-house has arisen, which was used in West Greenland before the Danish colonisation and which G. Holm! in 1884 still found in use at Angmagsalik. The long, common-house in Green- land is in fact nothing else than this house-type, built with beams of drift-wood to support the roof instead of stones or whale ribs. The fixed dividing wall becomes of no use and disappears, aS soon as a more convenient mode of supporting the roof, by means of beams resting on the side-walls, is found (cf. fig. 16); but the small, middle platforms remain in the form of a raised part or table, on which the lamps stand in front of the main platform in the long house (о in fig. 16). A house-type such as shown on fig. 15, which is intended for 2 families, each having a separate, main platform and con- siderably more space than if they shared a simple, single house, has arisen as the expression of the Eskimo tendency to crowd together, a tendency which is binding both in socio- logical and psychological regards. As soon as the Eskimos can obtain the drift-wood, they have been able to satisfy this tendency and thus, on the basis of the known house-type, build the long house with a single, long, main platform, on which each family has its “Бег” or division, separated at the sides only by a hanging skin. In July—August 1909 there were 5 tents to the east of the winter-houses at the settlement Umanark; these were oc- cupied by 6 families of in all 29 members. The tents lay scattered on the sides of a small valley-like depression and ! Gustav Holm: Etnologisk Skizze af Angmagsalikerne. Meddelelser om Grønland X. 325 were most of them farther from the shore than the winter- houses. The openings of the tents were not in any particular direction, but so that the in-dwellers could in each single case look out directly on the sea. The tents were placed on grassy ground and not on a naked, rounded rock-surface, as we so often find in the more southern parts of Greenland. The grass is warmer and it is not filled with gnat-larvae, as may be the case in the south. Outside the tents the dogs were leashed 4—5 together to one or other large stone boulder, whilst the half-grown puppies were allowed to play about. Of these 29 Eskimos 6 were married men, 6 married women, one widow, a half-grown girl and boy and the rest children’. The widow Krulé, an old, decrepit woman tottering about with a stick made of two pieces of wood, did not live in any of the 5 tents, though her married daughter occupied one of them and could have housed her without difficulty. She had no idea how old she was and the other Eskimos still less; by their way of it, she had always existed so long as they could remember. She herself answered the question as to her age with such inconsequent remarks as, she was now no longer of any use, or even, that she was so old that her lice no longer had a good taste; she was probably about 60 —65 vears old. According to information from Knud Rasmussen her tribesmen, who were tired of carrying such a useless ob- ject about, had left her on one of the bird-grounds two years previously, to look after herself or go under. Knud Rasmussen happened by chance to pass that way and took her with him on his sledge. Now she was eking out her existence here at Umanark, going round about the tents and picking up odds and ends of the food going. Her dwelling was made up of some old skins laid over a couple of poles, in the form of a ! During the stay of the “Godthaab” at North Star Bay, two other families and one unmarried, young man — in all 7 persons — were there; they had been brought from Cape York and were taken back there again. 326 very small tent, the height of which outside was 1°3 m, length 1:7 m and the breadth 1'1 m. Inside the space was so re- stricted that she had just room to sit up on the ground in front. Of platform or lamp there was no sign; her bed was a skin laid over a layer of grass. The diminutive tent opened towards the large tents, so that Krulé could keep an eye on what was going on. The summer-tent of the Polar Eskimos, which I have had the opportunity to see at Cape York and at Umanark, is in its present form not nearly so interesting as the winter-house, as the occurrence of wood in later years has had more effect on the construction of the tent than on that of the winter-house. The best hunters may have a tent-platform of wood, but we still also see the older tent-platform, consisting of stones placed together in a mosaic. As example of a Polar Eskimo tent I may describe the largest and best tent at Umanark. It was occupied by two families (Uvdloriark and Itsukusuk) and was fairly new. The first time I visited this tent, a sunny day in July, only the inner covering was on, while the outer covering lay in a heap in front of the tent. The inner covering consisted partly of skins of the bearded seal without hairs, partly of the same kind of skins with the hairy side inwards. On the front part of the tent and even a little along the sides, this inner covering was quite clear and slightly transparent, so that the sunshine filled the tent with a peculiar, clear, yet soft and pleasant light. The tent was turned towards the north, so that even at mid- night the sun shone into the quite pleasing room. This clear Fig. 17 shows Uvdloriark’s summer tent, seen from the side. In the back-ground to the right, the view extends in towards the eastern end of Wolstenholm Sound with the inland-ice behind. Fig. 18 shows the old Krulé and her little tent. The view in the background extends right across Wolstenholm Sound to the mountains on the north side of this fjord. Medd. om Gronl. XXXIV. [H. P. Steensby.] 327 skin is the ‘‘meat-side” of the bearded seal’s skin, the hairy side being carefully peeled off with an ‘‘ulo”; this is said to be a very difficult task. As it became colder a few days later, the outer covering was put on. This has the hairy side outermost and is not subjected to any special treatment in front. Both the inner and outer coverings each form a single piece sewed together; on the front, more upright part of the tent the coverings are however not sewed together in the middle line, from the ground up towards the top of the tent. The upper part of this slit is laced together with seal thongs, and the lower part forms the entrance to the tent. This is closed by flaps folding together over one another. When no one is at home, heavy stones are laid on the edges of the flaps, so that the dogs cannot break in. Uvdloriark’s tent could further be closed by means of a thick strap of seal’s skin, which at half the height of the en- trance was fastened round the tent; behind, this strap was attached on each side to another strap, which went over the tent and was fastened at the ends by stones laid on it. The framework of the tent consisted in front of a frame or gallows of 3 poles, of which the one was borne horizontally by the two others and supported the broad front-part of the tent, which was about 1m broad. The two upright poles were not on the ground but stood on a stone, the first of a con- tinuous circle of stones, which went round the inner side of the tent, with exception of the part at the entrance. The slop- ing poles, 9 in all, the principal of which were bound fast to the cross-beam of the top, rested at the other end on the highest stones in the inner row mentioned. The framework of the tent was thus quite loose, but the tent was moored by bringing the lower edge of the covering out a little on the ground and weighting it there with stones (cf. fig. 20). The height of the inside of the tent from the ground to the cross-beam of the top was 240 cm, but in the other tents 328 this and the other measurements were somewhat smaller. The greatest length internally from the entrance to the back was 420 ст, whilst the greatest breadth just in front of the main platform was 360 cm. The main platform itself, which in this tent consisted of wooden beams laid transversely on the rows of stones at the sides, was in the centre 195 cm from front to back. The side- platform, which consisted partly of wood, partly of stone, was 120 cm. broad on Uvdloriark’s side and pro- jected 110 cm from the main platform, whilst that on It- sukusuk’s side was only 70 ст and projected 90 cm; but Itsukusuk was not so clever a hunter as Uvdlori- Fie. 19 ark, being also younger and Diagrammatic ground-plan of a tent for 2 fa- still without children.

The boards of the main platform were covered with a layer of dry grass and above this skins of the reindeer. Just as described for the arrangement of the winter-houses, here also the women had their place outermost at the sides of the tent, where they sat by the side-platform and the lamp standing on it. Here sat Kagssaluk, whom the photograph given on fig. 23 shows in home-dress, managing to look after her small 329 children, whilst at the same time working with skins and at- tending to the flame of the blubber-lamp. The lamp stood on the boards of the side-platform, sup- ported by 3 stones (cf. fig. 21). Soapstone is still used for the lamps, but cooking utensils of soapstone are disappearing and those of tin and iron are taking their place. In the bend on the most convex side of the lamp lie as a rule shining lumps of white, unmelted blubber, while the bottom of the lamp is Fig. 20.

The manner in which the coverings are anchored by stone-ballast is shown between b and e. bc is meant to represent the divided main platform, only the wooden floor being shown. covered by the melted, floating blubber. The flame is placed within the bend on the less convex side of the lamp, which is turned towards the main platform. If the lamp has to be lighted and there is no melted blubber in it, the women have to melt the blubber by chewing and then spit it out into the lamp or directly on to a prepared wick of moss. The latter must be rolled, namely, between the hands before it can be used, until it makes a fine dust. Some of the moss is strewn along the edge of the lamp where the flame is to be, whilst the rest is sometimes laid as a reserve in one of the pointed corners 330 of the lamp, from which it is taken later between the thumb and forefinger and strewn over the places, where the flame re- quires brightening. With the lamp-stick, which as a rule is an unprepared piece of bone or wood, the lamp-moss soaked with the blubber is arranged in a series of pointed tufts. Then these or at least some of them are lighted at the top and allowed to burn for a while; the lamp-stick is now used to bring them all into connection, and the tufts still not lit are added, so that a long flame is obtained which burns at the back of a low wall of moss (a cross-section of this with the flame is shown to the left in the lamp on fig. 21). The magnitude of the flame thus depends on how long the moss-wall is made Z S ) SS 4 Se, LOT OT LIL LIL PL I IT LIT LTT LILLIA LL IL LIT IT PLV LLL LLL LLL. Fig. 21.

In the former case, the flame may extend over at least */aths of the one side of the lamp, whereas in the latter. case it only requires to be a few cm. The size of the lamp itself is extremely variable; the breadth of a cooking-lamp be- tween its two pointed corners may be normally from 30 to 70 cm. While the lamp is burning, it must be constantly attended to; with the stick the woman works along the moss- wall smoothing and making it regular, so that the flame should burn clear and evenly without smoking. This apparently so simple treatment is in reality very difficult and requires so much skill, experience and care, that none but an Eskimo 331 woman can exercise it. Just at the moment of lighting, the flame may smoke somewhat, giving off a bluish smoke and jumping a little, but as the heat rises it becomes quieter and burns with a yellowish colour. To make fire matches are now used, if they are to be had; otherwise fire is made with an apparatus which consists of a piece of sulphur pyrites and a piece of quartz, or even of old steel. Further, a tuft of moss is used somewhat larger than a closed hand and in a small hole on the top of this a small clump of the woolly seed of the polar willow is placed. When fire is to be made, the moss with the seed is placed in front on the platform or on the knees and the sulphur is held about 3 cm over the seed, into which the sparks fall when the sulphur is struck. When the seed-wool has obtained a spark that catches, it is blown upon until it spreads out in the wool over a space of quite half a square cm. А small piece of moss is now torn off, steeped in the melted or chewed blubber and used as a lighter. In this manner the Polar Eskimos can produce fire in less than a minute. Over Kagssaluk’s lamp and about 90 cm from it hung the horizontal, wooden grating for drying clothes, which was 96 cm long and 50cm broad. It was suspended in strings from the frame of the tent. A skin-strap, which passed up round a couple of stakes in the board and could be moved along these, suspended a cooking vessel consisting of an old metal pot. The other house-utensils on the side-platform, which to a cer- tain extent plays the part of kitchen, also spoke distinctly of intercourse with Europeans and Americans. Thus, at a certain, typical moment there stood on Kagssäluk’s side-platform, in addition to the lamp, a large metal pot, a metal basin, a coffee pot, a pot with seals’ intestines, an ‘‘ulo”, as also a large piece of narwhal meat. Until quite recently, however, the water-jars used were made of skin sewed together and made water-tight at the seams by the blubber-mixed substance, which is scraped from the ‘‘kamikker” on cleaning them. XXXIV. 22 332 In addition to the care of the children, sewing and pre- paring the skins, attending to the lamp and drying of the wet clothes and kamikker, the woman has further the housewife’s task of preparing the food. This task is however not so great, as the man cuts up the booty and brings the pieces of meat into the tent or winter-house. She has thus only to keep the pot boiling, and the art of cooking among the Polar Eskimos is not very developed. Frequently the meat is taken from the pot and eaten before it is quite cooked. Quite raw meat is also eaten in large quantities; the fondness for frozen and rotten meat has already been mentioned. The skin of the white whale and narwhal, the so-called Mattak, is eaten in large amount and is a much-liked and quite pleasant dish. Fresh- water is always used for cooking by the Polar Eskimos. For about 9 months of the year all the drinking-water must be ob- tained by melting freshwater ice over the blubber-lamp; the ice is fairly easily obtained from the ice-bergs and ice-clumps, which lie scattered about frozen in amongst the sea-ice.

In front of the tent stand Itsukusuk and Kags- зак, both in house-costume (except Itsukusuk’s Kamikker). It is clearly seen, that Kagssäluk’s left breast is somewhat atrophied; this is probably connected with the fact, that her place is always on the left side of the main platform (at the cross on fig. 19), and that she has her children on her right, in towards the middle of the tent, so that as a rule only the right breast is used in giving milk (cf. fig. 23). Fig. 23 shows Kagssaluk and her two children, sitting in house- costume inside the tent at the place marked in fig. 19.

XXXIV. [H. P. Steensby.] MV The practical sense, which is so apparent in the structure of the Polar Eskimo house, reveals itself also in the skin- clothing; and various features, which at first sight produce a comic or incomplete impression, on closer acquaintance are found to rest on practical adaptation to the climate or the ne- cessities of the material. The separate parts of the clothing are: kamikker (boots), skin- stockings, trousers, under furcoat, over furcoat and mittens. When the Polar Eskimos come into a winter-house or a tent, where the lamps are lit and the room warm, all the clothes are taken off with exception of the trousers. The women must always keep the trousers on, but it is quite common for the men to lie on the platform with nothing but paradisiac costume. The trousers of the women, which are of blue foxes’ skin, are but some few — about 10 — cm long and just come up to the seat and the uppermost part of the thighs. As a rule two skins of the blue fox are required for a pair of woman’s trousers. The men’s trousers on the other hand are of bear’s skin and of considerably greater length, extending from the knees to the upper part of the thighs, where the band is pulled together with a string which thus comes to rest on the troch- anter major of the thigh-bone on each side. For a Euro- pean it would be very difficult to keep up the trousers in this manner; but for the Eskimos it is customary and natural. And it is also very practical, in agreement with the material and the conditions. If, namely, the band of the trousers, as with 22" 334 us, came above the hips, with the thick, stiff skin it would seriously interfere with the suppleness and bending the joint between the thigh and the hip-joint. The position in the kayak with the legs stretched out in front, the lateral position on the sledge, the sitting positions on the platform in the house, the bent attitude on cutting up the booty — all cases require the clothing to respect the natural jointing of the body, which is at the hips and not in the middle- line. The warm bearskins are quite indispensable for trousers in the cold climate; the only kind of skin in polar regions, which is just as warm, is that of the musk-ox, which the Po- lar Eskimos have also occasion- ally used for trousers. But this skin has practical disadvantages; thus, where dirt, blubber and blood can readily slip off from the hairy covering of the bear- skin, the musk-ox has such a woolly covering, the hair is so Fig. 24. A boy with kamikker and bearskin trousers; dense, that the dirt rather gets he is holding up his arms, so as to show how the trousers are supported glued on to it and sticks fast. Practical arrangement also characterises their other clothing. But it cannot be said that the clothing for the feet and legs, which the women have, is very practical or suited to movement. As their trousers do not come far down over the thighs, the kamikker and stockings must come far enough up to do so. For this reason the women wear stout and long kamikker, which come far up above the knee and make it appear as if they had the legs of 335 an elephant. The kamikker of the men, on the other hand, only reach to just below the knee, where the upper edge is fastened by a string round the skin-stockings. The kamikker may also be drawn tight at the ankles by a leather thong, which is passed through two leather loops fixed on the side of the foot above the middle part. The kamikker of both the men and the women are of seal's skin, which is treated in warm water and then scraped, so as to remove the hairs and the dark outer layer. Their colour is thus light. On the other hand, it does not appear that the Polar Eskimos, like the more southerly Greenlanders, use urine for the tanning of the skins. On the feet of the kamikker an extra sole of specially strong skin is sewed. This sole-skin is first scraped on the upper side, i.e. the inner side cs LE) of the skin, by means of a curved blade of an ‘‘ulo”, so that it should not be too thick and unbendable. After it is then well-chewed once more, it is sewed along the edge which is turned up a little. During the sewing the women constantly use their teeth on the edge of the sole, to make it more pli- able and easier to pierce with the needle. ‘The method of sewing on the sole is quite the same as in attaching a patch on a hole in the skin-boat. The stitches are not passed in and out through the skin and foot of the kamik, but along both skins, so that no stitch goes right through either of the skins. On the outside the skin of the sole has a fine wrink- ling, produced without the use of any special instrument. The Polar Eskimos do not have any over-shoes, such as were worn by the Eskimos in Southern Greenland up to the 18 century and which are mentioned by Roald Amundsen as still occurring among the Netchillik Eskimos. Under the kamikker are worn the skin stockings, which have the same length as the men’s and women’s kamikker respectively. They are of hare-skin, which is white the whole year round in the polar regions. For this use the hare-skins 336 are said to far excel those of the fox and dog; they are softer and more pliable, do not cause sweating of the feet so readily, are more easily dried and never become so stiff and uncom- Fig. 25.

Dried grass is used as stopping between the kamikker and hare-skin stockings, especially under the sole of the foot.

This is inserted in the kamik between this and the hare-skin stocking and in front of the shin- bone, so that it goes from the in- step to the knee. Its length is ca. 35 cm and its breadth 16—18 cm.

In South Greenland it is common first of all to wash the dirt from the kamikker, büt up here, where water is a more costly commodity, they are scraped clean with a bone instrument (fig. 26). After this a scraper 337 with a blade of iron and a short handle is used for the “Кат- juting” (fig. 27). In scraping the hollow edge of the blade is held forward. These two instruments, the kamik cleaner and the soften- ing scraper, must not be confused with the true skin-scraper, which is also quite different from the ‘‘ulo” ог woman’s knive, of which again there is a couple of forms. The blubber on the inner side of the fresh skin is cut away by means of the ulo. Then the skin is treated in warm water and afterwards the hairy layer is scraped off with a skin-scraper with an iron edge (fig. 28). Of the forms of шо (cf. figs. 53, 58, 61) the one with the strong curved edge is used in cutting the skin and as the usual instrument during sewing, in short it plays the part of scissors. The women now and then sharpen this against a stone or by using the sewing-needle as a ‘‘steel”. On the upper part of the body, as mentioned, the men and women wear innermost a pelt which is made of the skins of the Auk or Little Auk, sewed together with the feather side inmost towards the body. This bird-skin shirt is soft and warm, but it has the disadvantage, that it is impossible to keep it free from lice. A linen shirt was therefore the most highly esteemed article of clothing one could offer a Polar Eskimo, for the reason, so they said, that they could see the lice in it It is not to be assumed, however, that they have quite given up the fight against their small plagues in the bird-skin pelt, as they have constructed a practical lice-catcher, consisting of a stick 35—40 cm long, on the end of which a piece of bear- skin is fastened; in this the insects get trapped when the instrument is rubbed in under the feathers. Naturally, the “catch” is eaten by the Polar Eskimos, as by most other na- ture-folk. There is further a special skin-scratcher, consisting of a wooden shaft with a head of bone. To make a bird-skin shirt means very considerable work. The skins are pulled off the birds whole, so that the feathers 338 come to be inside, and hung up for preserving and drying on a thong, which is passed through a hole made with a bone needle. When the skins are again taken down for treatment, they are subjected to a very careful process of chewing; the women place the skin in their mouths and chew it, turning it round and round in the mouth, until every little bit of the skin has been chewed. The skin is thus softened and made smooth, and the fat sucked out. After drying it is then cut up. F The process of cutting up is shown on fig. 29, which represents a Little Auk skin turned inside out, on which 1 have endeavoured by means of letters and dots to show the lines along which the skin is cut up with the ulo. First the tail is cut off along the dotted line Б В’, and then the ends of the two skin-stumps of the legs A and A’ along the dotted lines at 5 and с. The third and fourth sections are made along the profile of the figure from В to 6 and from В’ to c, so that the hind end of the skin, instead of 3 small, comes to have one large opening. Fig. 29. Then the skin of the one wing is cut off along the line HK. The next cut begins in the middle of the skin of the other wing at G, is carried from there up to D and further to E. Thereafter the skin is cut along profile line from К to A and then the middle line DF of the neck- skin. As a rule the line GC, the uncut wing, is not cut until the last. The skin is now folded out like a plate and can be sewed together with others, for which purpose, however, it is somewhat clipped along the edges. About 100 skins of the Little Auk is used for one of these inner pelts, whilst of the Auk not a fourth part of this number is required; but the pelt of the Little Auk is said to be the softest and warmest. 339 The person from whom I had most opportunity to obtain this information was a young, pregnant woman Inadtliak, who was busy preparing for future use an ‘‘amaut”, or a pelt in which to carry the child on her back. She had made a shield-shaped piece of tanned sealskin for her new Little Auk pelt, to be placed outside at the back, so that the pelt came to stand out at the back and form a space for the expected Fig. 30. Inadtliak and her litte son. She is sitting in the open on some skins and, the sun being warm, has for a moment taken off both her kamikker and bird-skin pelt for mending purposes, child, which would be lodged between her bare back and the bird-skin. For the time being, she stopped up the space with the hood of the skin-pelt, so that her back should not freeze. Whilst the inner pelt has the feather side innermost, the outer pelt, which is made of the skins of seals, foxes or rein- deer, always has the hairy side outermost.. The sealskin pelt is used in summer, whilst the others belong to the winter, though the old Krulé went about in a fox-skin pelt during the 340 summer. On very sunny and warm days many persons only wear the inner pelt. The pelt is provided with a hood, to be pulled over the head, so that only the face is bare surrounded by a skin border. The women, who are carrying a child in the ‘‘amaut”, have however a loose, helmet-shaped skin hat, which is fastened under the chin by a band; they use further Fig. 31. Kagssäluk with her two children, the girl Nata with the hood of the foxskin pelt over her head sitting in the amaut of sealskin pelt and the boy Inuterk, who like Natu is clad in a foxskin pelt. a narrow, skin strap which is fastened at the one end in the middle line of the pelt between the breasts; from here it is carried round the back under the bag or pouch, to prevent the child from sinking down, and is then brought right round the other side and buttoned, the free end having a short cross- piece of bone which is twisted under the fixed end on the breast. 341 After their intercourse with the Danish Literary Expedition of 1903—04, the men have found it practical to imitate the Europeans and have a pocket on the front of the pelt. They use it chiefly to hold their pipe and tobacco; sometimes it is ornamented with a pearl-button. The upper parts of the pelt over the shoulders and breast are sewn and cut according to Fig. 32. the same as fig 31. a traditional custom, which will not be further considered here, but a close comparison with materials from other tribes would certainly give very interesting information regarding the devel- opmental history of the dress. The same applies also to the flaps or lappets, which end the pelt below, in front and behind; they are a little larger behind than in front and somewhat larger for the women than the men. With regard to these lappets, however, I cannot refrain from one remark. 342 It is a well-known fact that their distribution agrees fairly exactly with that of the Eskimos, whereas all other arctic peoples have a quite rounded, straight-cut edge to their-coats, even though this, as is most usual, reaches a good piece down on the legs, sometimes even almost to the ankles. If we look now at the skin-coats of the Eivillik and Kinipetu Eskimos on the west side of Hudson Bay and Barren Grounds, which have only become known within recent years through the figures of Canadian travellers, especially A. P. Low, we are most struck by the extent of these lappets, their breadth and length. The lower edge of the pelt reaches at the sides only to the hips, but from here the coat slopes down in front and at the back, so that the side-edges meet at the level of the knees, or even a little lower down, as they form a wide sweep below. In such cases we might as well talk of notches at the sides of the pelt as of lappets in the middle. And my idea is, that the Eskimos have originally worn a fairly long, loose pelt, but that this has proved to be unpractical in the narrow kayak, when the Eskimos changed from the kneeling position in the birch canoes to the sitting position in the kayak. In adapting them- selves to the narrower space for sitting in, the men have then got the coats made with the opening at the sides, whilst the front and back parts have remained as large flaps, as there was room for these in the kayak. Gradually, however, these flaps, which were only useless rudiments, have decreased in size to the small lappets, which we find among the Polar Eskimos and which should thus be the last apparent reminders of the long pelt. That the women’s coat has also passed through the same developmental process does not contradict the theory, as it would be a common correlation phenomenon, that the flaps should also be the same in the woman’s coat. And the fact, that the lappets among the Eskimos are always greatest on the woman’s coat, just indicates that the develop- ment may have proceeded along the lines described. 343 The Polar Eskimo coat and especially that of the men is thus constructed on the articulated principle with bare skin at the joints so as not to hinder the movements. For the sake of warmth an edging of the long-haired bear-skin is often used at the joints, for example, round the upper edge of the women’s stockings and round the wrists; on the man’s pelt, probably for similar reasons, there is a small bear-skin flap, which sticks out under the chin. When it gets very cold, the joints are bound round with fox- tails, and it is also said that a fox’s tail is hung over the nose from the forehead. Short skin mittens with one finger are worn on the hands; they are filled with dry grass. Even in summer there were some among both the men and the women who went about with mittens on; thus the old Masaitsiak wore them even on mild, sunny days. When the women are sitting down and their hands are freezing, they stick them down in the long kamikker we | Fig. 33. inside the hare-skin stockings. A boy in bearskin trousers and sealskin pelt. The skins, which are to be used as pelts and thus have the hair kept on, must also undergo a long treatment. First as much blubber as possible is cut and scraped off with the ulo; then the skin is stretched out on the ground to dry, being held down by numerous pieces of bone — 50 or more — which are stuck into the ground through holes in the edges of the skin. The skin is thus tightly stretched out with the inner side uppermost. 344 When it is quite dry, the women take the skin and chew it thoroughly on its inner side, in order to get as much fat out as possible and make it soft. Then it is dried once again and scraped with the blunt-edged skin-scraper, so that it becomes soft and flexible. There can be no doubt that the chewing of these large skins is exceedingly hard work. A woman is said to be able to chew two reindeer skins in a day, but she can- not keep at it from day to day. The cutting-up of the skins into pieces of clothing is done by the women, quite freely with the curved ulo, without using any measurer or model. The model they follow must be so fixed by tradition and so much a matter of practice, that it is used almost reflexly and unconsciously. The Eskimo works with such ease at a skin-coat, that one gets the impression, she does not use much brain-work on it. In sewing she sits on the platform with the legs crossed, in the fashion of the Turks. The skin is held with the feet, for example, by fixing it between the big toe and the second toe on the right foot, by holding it between the big toe of the right foot and the left leg or by placing it between the left knee and the right foot. The needle, which now is of European make, is carried from the right to the left. With thicker skins a thimble is used on the forefinger. The thread is unravelled as it is used from a bundle of sinews, which is softened in the mouth. This is constantly being used during the work, as the skin edges to be sewn together are softened by chewing, and the finished seam is treated in the same manner. A pin-cushion is some- times used for keeping the needles in, made of a small skin- bag containing some moss, and all the sewing requisites are kept in a small skin-bag. True ornaments or other colours than those naturally possessed by the skins are not used to any extent on the dress, nor on the implements. This comes partly from the lack of ornamental materials, partly from the fact, that the 345 practical struggle for life — at any rate in earlier years — engaged all their powers and interest, so that no energy was left unused which could be converted into such uneconomical things as ornaments. Among the Polar Eskimos all things are judged by a purely practical standard; but as the struggle for life has now been made easier for them in several ways, it will be interesting to follow their future development and, for ex- ample, observe how a desire for ornamentation with the use of European buttons, pearls, bands etc., will also certainly develop amongst them. A beginning of this kind was indeed already to be noticed. Thus, one of the women (Fig. 30) was wearing а narrow skin-ring round the neck and for 7/sths of its extent the front edge of the ring was beset alternately with small, black and white beads; further, three small fringes on the front edge of the ring each ended in a large, glass bead and the middle fringe was ornamented by a large, white button. I saw a more indigenous case of ornamentation on the kamikker of a young woman (Fig. 86). In the middle line above and in front these had a 3—4 cm broad piece of black skin, which composed more than !/srd of the length of the kamikker in front of the leg and looked quite pretty. In answer to my question, I re- ceived the explanation, that she had not had sufficient of the light-coloured skin for the kamikker and had to eke it out with the black; she had thought it best therefore to make both kamikker in the same way. Nevertheless she had also under- stood how to make them so as to look best. It is also pos- sible, that the Polar Eskimos will in future simply take over the West Greenland ornamentation, adapting it somewhat to their special conditions. As will appear from the photographs given here of the Polar Eskimos, the men wear their hair long and usually hang- ing loose down from the head, so that they are obliged every moment to give a small toss with the head or take their hands to clear their eyes. Sometimes, however, they use a thin 346 string of skin as hair-band, bringing it from the upper part of the forehead round the temples to the back of the neck. The women almost always have their hair bound up in a string of skin like a chignon or a small top. Only one little girl had obtained a red band for the hair, and there did not appear to be any great desire to possess coloured bands. The little older children were clothed in quite the same way as the adults. The boys had the bearskin trousers, rea- ching down to the knees, whilst the girls have the long ka- mikker and the small, short foxskin trousers. The smallest children seem however to wear generally a loose hood; I saw two children with amulets round the neck, consisting of the head and claws of a raven. The-very small children unable to walk are constantly carried in the ‘‘amaut”, where they are ‘‘cradled and rocked”. It is only when the child has to have milk that it is taken out of the back-pouch; this is done by the mother leaning forward and carefully shaking the young one out over the one shoulder. The youngest children are suckled for a verv long time; I have seen a 5 years’ old boy regularly taking milk at his mother’s breast, but even older children are said to do the same. Water is for the greater part of the year too costly a com- modity to find any other use than drinking, so that neither the children nor the older people have known what it is to be washed. I have however seen a mother dry her child's dirty fingers on a white gull’s skin. Such is also sometimes used by the grown-up people in the tent, to clean their fingers after they had eaten; possibly, however, this use is of more recent origin. In the previous pages of this chapter I have just touched upon the question of the woman’s work and place among the Polar Eskimos. In contrast to most other hunting-peoples in milder parts of the globe, where the chief occupation of the woman is the collection of easily obtained objects of food, here 347 in the Polar North her duties with the preparing of skins and making of clothes mean work of a mechanical kind and lead to a special development in various directions. If we enquire what special kind of mechanical work it is that lays most claim on the time and physical powers of the woman, we find that it is such a primitive form of activity as the chewing of skins, and next the scraping of skins. Then come cutting and sew- ing with sharp instruments such as tke knive and needle. The only division of labour practised among the Polar Eskimos is that between man and wife. Each man and each woman, to be considered as a fully qualified member of the tribe, must be able to do and carry out all that may fall to the lot of his or her sex. And this is by no means little. There is perhaps no nature-people, where the requirements in the way of mechanical production are greater than among the Polar Eskimos. This is connected partly with the difficult conditions of life in Polar lands, partly with the great varia- tions in the seasons, which require not only different kinds of dwellings and clothing, but also different apparatus for the different seasons of the year. Making of the apparatus falls to the man. The material he chiefly works in is bone and wood, and now also metals, which in earlier days were replaced by stone and by the natural iron occurring in the region of Cape York. If we en- quire, in the same manner as for the women, what is the spe- cial, mechanical hand craft exercised by the men, we find similarly that the sharp instruments for cutting and hewing play in the Polar Eskimo’s occupations, compared with European hand-worker’s, a less important part than such instruments as are used for filing, sawing, scraping and boring. Even the teeth also play a considerable role with the man, for example, to soften the skin-thongs or straps, loosening of knots and as a fixed holding-apparatus on numerous occasions. The fact seems to be that the Polar Eskimos have not XXXIV. 23 348 adapted themselves to the European methods to the same extent as they have to the European apparatus. These have just been taken over into the methods of the stone-age and naturally have altered and modified this, but the underlying traditions of the stone-age are constantly to be noticed. The transition from the stone-age to the use of European iron apparatus had already had a good preliminary before 1818 in the use of the meteoric iron, and the transition proceeded slowly in the course of a couple of generations, materials being introduced little by little by intercourse with the whalers and expeditions as also by wreckage and the forsaken ships of expeditions. When Peary began his expeditions in 1891, the true stone- age was already past, and the era he introduced, by providing the Polar Eskimos with the most modern guns and other apparatus for hunting, is best described by saying, that he brought in among the Eskimos the keen production of modern European-American civilisation. In this way a danger has arisen for them, as it is conceivable that they will now be able to destroy or at any rate greatly decimate the stock of the bears and foxes especially. And without the skins of these animals for clothing, their cold land will become almost uninhabitable. It must not be believed, that any and every kind of Euro- pean implement found a welcome in the eyes of the Polar Eskimos. They have had a remarkably good understanding of how to choose out the kinds and forms, which were best suited for their requirements. The most useful European instrument a Polar Eskimo can obtain is still a file. By means of steel-files pieces of whalrus and narwhal teeth are worked up into harpoon points, as foreshafts of the harpoons, as pro- tectors under the sledge-runners and for several other purposes. For sawing is used a ship’s saw, quite 30cm in length, of the best American manufacture; the back-edge of the saw is ground sharp and used for hewing and chopping. The steel-knife is used for cutting up the animals taken in the hunt and plays the 349 part of both a cutting and scraping instrument in the making of apparatus. For boring, on the other hand, there is still used the Eskimo drill with a bone mouth-piece, the bow being usually formed of a seal’s rib and a skin thong, and the point is now always of metal. It is in fact a point of no little cultural interest from the historical side to make clear, what European apparatus can be absorbed by a strange culture. We see very clearly among the Polar Eskimos, that they have chosen the apparatus, which for them meant a reduction of labour in their old modes of procedure. But they have still held fast to their old methods and the old forms, in so far as they were not obliged to modify them in using the new apparatus. The Polar Eskimos are thus to a certain extent still people of the stone-age, who are employing the help yielded by the modern mechanical methods, without adopting the mental ac- companiments. For them iron is a material of similar kind to bone, and they deal with bone and metal in quite the same manner, with the file. | found an interesting example of this in a harpoon-point (fig. 34) of the Polar Eskimo Manigssok; every part of it had been filed out of a massive piece of iron. As a rule only the point is of iron, whilst the head-piece is of filed bone (cf. fig. 35, which likewise shows the second of the two forms of harpoon-points common among the Polar Eskimos; it is used for the white whale and narwhal, whilst fig. 34 is for the walrus and seal). The iron point, fig. 34, is in all details an exact copy of the commonly used form. It is likewise a witness of the surprising, technical skill of the Polar-Eskimos, as with- out any other assistance whatsoever, with the file in the right hand and the object in the left, they are able to make such a uniform and faultless implement. During the work they support the left hand on the knee or the thigh, but there is no talk of making measurements or of copying from something 235 350 already completed. They produce so to speak by “heart” the forms of apparatus they are accustomed to. One cannot help being impressed by the ease, rapidity and practical sense with which they work, in spite of the lack of all the many means of assistance, which the European work- shop affords our workers. I was present, for example, when Samik sawed through a piece of an antler of a reindeer, long- ways with a ship’s saw. First of all he chopped off the round tines on two diametrically opposite sides by means of the sharp back-edge of the saw, so that he was freed from cutting Fig. 34. Fig. 35. Harpoon point; a piece of leather Harpoon point of bone with a thong passes through the cross- small iron tip, fixed by a nail. hole. 7,6 ст long, up to 1,6 cm broad, 13,8 ст long, up to 3,7 cm broad, 1,5 cm thick. 2 cm thick. through these parts. A hand-worker would do exactly the same. Then he began to saw the antler, holding it in the left hand, lightly supported on the left leg. Later also, he sawed off some small pieces in the same manner. It looked most danger- ous but was carried out with steadiness and accuracy. They all seem to be able to use their hands with the same cleverness and certainty. I can remember, for example, how Uvdloriark sat outside his tent and with the back-edge of his ship’s saw cut into shape a walrus-rib, which was to be used as the frame of a drum. He held the bone enclosed in his left hand, with the back of the hand resting on the legging of the kamik of the left leg, and cut right down towards the index 551 finger which lay along the bone. He could bring the cutting edge of the saw with force right in under the index finger without cutting himself, and the accurately cut pieces being chipped off the bone quickly acquired the desired form. Later, the bone thus cut down was bent by alternately working with the hands and dipping it in hot water. After hunting the Polar Eskimos take the greatest interest in hand-work. We cannot help noticing the attention and intelligence, with which they take hold of and consider an apparatus, they get into their hands, the use of which they know. Nor would it be possible for them to sit and work at their apparatus with the care and accuracy they employ, if a certain amount of pleasure in working with the hands was not present. “Hand culture” stands very high among the Polar Eskimos and it has scarcely at any time been higher than it is now. On this point as on others there can be no talk of any ‘‘demoralisation” among them. On the contrary, their acquisi- tion of the European aids has opened up the possibility of further development of skill and ingenuity in overcomiug tech- nical difficulties, which in the old days of the stone-inplements could only be overcome by the employment of an enormous amount of time and patience. The child is taught partly by play and imitation, partly by the direct instruction of the father. Toys for the smaller children are made by the father from bone, in the shape of figures representing animals and human beings. It is not im- possible, however, that some of the figures do duty as a kind of pedagogic means of instruction. The larger boys make for themselves toy-harpoons, toy-sledges, toy-stools for Maupok- hunting etc., and these are true copies of the apparatus of the older Eskimos’. Before the Polar Eskimos obtained guns, and before the Ponds Inlet Eskimos taught them the use of the kayak and 352 the bow and arrow, about 1862—63, the dog-sledge, the har- poon and the lance were their principal means of making a livelihood, and they are still that. It has already been men- tioned, how the first expeditions found these apparatus com- posed of small pieces of bone and wood bound together. At the present day the lack of wood is not so great; but we can still see sledges on which the runners do not consist of a single piece of wood, but of several pieces bound together with thongs. For example, Ajorsalik had a sledge, in which the one runner had 7, the other 5 pieces of wood, which were exactly fitted to each other and securely lashed together. Each of these sledge runners was 2,5 m long and 17,5 cm high; of this however 1,5—2,8 cm went to the shoes of the runners, which in front were thinner than behind. The breadth of the shoe is ca. 2—2,5cm. In front the runners curve evenly up- wards, and a little before the front end begin the cross-trees, which in Ajorsalik’s sledge numbered 12 in all. The two up- rights behind rise 75cm above the sledge and are connected with one another by a cross-piece and a couple of intercrossing straps. The breadth of the sledge from runner to runner was only ca. 55 cm, whilst the cross-trees were 60 cm long and thus extended a little beyond the runners. This long, narrow form is characteristic for the Polar Eskimo’s sledge and dis- tinguishes it for example from the shorter and broader sledges used in West Greenland. Instead of shoes of filed pieces of walrus and narwhal teeth the Eskimos now also use iron-shoes. There are even a few of the specially expert hunters who now keep two sledges, one with ivory shoes and the other with iron shoes. The former, namely, are said to be best on the wet ice in the au- tumn and spring, whilst the iron shoes are best on the ice during the rest of the winter and on land. The method of giving the runners ice-shoes is also known, melting snow being rubbed on them; it is chiefly used in the autumn. Early in 353 March 1892 Peary whilst on a sledge-journey observed a some different procedure, which he describes as follows. ‘‘The bot- toms of the runners (are first covered) with a continuous strip of thick walrus hide, 2!/2 inches wide, with the hair on. This was fastened on by rawhide lashings passed through slits cut in the edges. When this was frozen hard, a coating of snow dipped in warm urine was applied and shaped and pressed with the hands, until the entire length of the runner was cov- ered three-fourths of an inch to an inch thick. This, in turn, was allowed to freeze solid, and then chipped and smoothed with a knife, and finally rubbed down with the hand dipped in water” 1. Whilst the first expeditions usually met with small packs of dogs it is now common for good hunters to have a consi- derable number. A man like Samik has a score of dogs. A single team may now consist of up to 12 dogs, though 6—8 is about the usual number. If a man has two teams, one of them is often driven by a boy, a son or relative, who may have almost the position of a servant. The method of driving is highly developed and of the same kind as in West Green- land. The team is directed with the long whip and with shouts of definite meaning for stopping, turning to the one side and the other, swifter movement, danger, bear and so on. These signals are not common for all, but different for every one. Each driver himself trains his dogs and teaches them his own signals, so that it is very difficult for others to drive them. The Polar Eskimo dogs belong to a specially large, fine and strong race, which however stands near to the sledge-dog of West Greenland. In West Greenland the dogs are always allowed to go loose about the settlement; among the Polar Eskimos they are always tied up, and they are better and more systematically fed than in the south. The natives are simply 1 Northward etc. Vol. I, р. 228. 354 obliged to do this up there, where the dogs cannot themselves go and seek for food on the beach, as they would then rob the food-depots or break into the houses. Just as in the more southerly West Greenland, the dogs are sometimes placed out on the small islands in the summer, where they are permitted to run about loose, but even here they are fed with a certain amount of regularity, which however does not always mean daily. Such a ‘‘dog-island” lies off the coast at the settlement Umanark. In order that the dogs when fastened in the leashes should not be able to free themselves by chewing through the leather, it is said to be common for the dogs, when still pup- pies, to have their molars crushed by means of a stone!. Dog-flesh is only eaten in cases of want. The two common forms of harpoon-points and their differ- ent use have already been described above. It would be of considerable interest to obtain an account of the different forms of harpoons. I shall not attempt to give such an account here, however, inter alia because I was unable during my short stay to get the matter fully cleared up. I shall therefore content myself with some few preparatory notes. A throwing board is not used for any kind of harpoon. Instead, the shaft of the harpoon, somewhat below the middle, has a small, firmly lashed bone button, which serves as support for the hand in throwing or striking, the button being held between the third and fourth finger. Quite provisionally for the sake of description and to give a basis for future investigations, | may divide the harpoons into heavy and light. The heavy harpoons have a shaft which the hand can scarcely reach round; its length is usually about 1,5m, and to this has to be added a foreshaft of bone, the length of which may vary somewhat greatly (ca. 20—40 cm). Of the heavy harpoons again I have seen two kinds, namely, 1 Mylius-Erichsen og Moltke, 1. c., р. 232. 555 one with detachable foreshaft and another with а foreshaft which is firmly lashed to the end of the harpoon. Of the light harpoons I have only seen one kind with firmly lashed fore- shaft and at the same time a little less in length than the foregoing (in all about 1,5 m). The heavy harpoon with detachable foreshaft is used from the kayak; the line passes from the point up along the shaft of the harpoon and is fastened by a bone-ring to a small but- ton — now as a rule a nail without head — which is fixed into the shaft a little beyond the. bone-button serving as sup- port for the hand. As the foreshaft is broken by the struggles of the wounded animal in the water, the point of the harpoon is set free and also the line from the shaft, and the latter floats up on the water. The various harpoons with fixed fore- shaft seem on the other hand always to have another arrange- ment to let the point and line free. Along the shaft lies a fairly tight thong, about 75cm long, which is firmly attached to the shaft at the ends and at one spot in between; a coil of the harpoon line is now placed in under the thong and round the middle fixed point in such a way, that it runs out at the moment there is a pull upon the harpoon line. This mode of attachment is specially practical in the case of harpoons, which are not thrown but thrust into the animal and the shaft with- drawn. A heavy harpoon with fixed foreshaft is used in the walrus- hunting on the ice in the spring. A light form of harpoon with fixed foreshaft is used in the Utok hunting of the spring, or the hunting of the seals which have crawled up on the ice. Which forms of harpoons are employed in the other methods of hunting, as for example on the smooth ice and in the Mau- рок hunting, has not been cleared up with certainty. It will be of importance especially to ascertain, whether a harpoon with fixed or detachable foreshaft is used in the Maupok me- thod. An interesting question is also, whether the Polar Eski- 356 mos, before they learnt the use of the kayak, perhaps did not use harpoons with detachable foreshaft at all. These questions may have significance for the solution of the whole problem regarding the origin of the Eskimo culture. Of the lances I have only seen the kayak lance; this has a detachable foreshaft with firmly attached point. Its length is a little less than that of the kayak harpoon, but it is thick and heavy like the latter. The foreshaft is sometimes a long piece of bone with an inserted, short and flat iron point, sometimes quite a short piece of bone with a long iron point inserted on it; the latter is filed out of a piece of iron bar. As this lance is also used as a throwing implement from the kayak, a small bladder may be fastened at the upper end of the shaft of the lance, so that the lance floats on the water, when it breaks loose from the animal struck. On fig. 36 this small bladder is shown lying at the back of the kayak just in front of the large hunting-bladder. With regard to the bow and arrow and the kayak, the Polar Eskimos use them just as the Central Eskimos and especially the Baffin Landers do, as it was from Ponds Inlet, аз | have shown above, that they have learnt the use of these implements. The bow is what F. у. Luschan has called a ‘‘com- posite and strengthened” bow to distinguish it from the true “compound” bow, which has its finest representative in the Asiatic, so-called Turkish bow. The Polar Eskimo bow consists of 3 pieces of reindeer antler, the two meeting-places of which are covered by an upper and under plate of the same material and bound round by leather thongs; on the back of the bow there is also a number of longitudinal leather thongs or, in very fine examples, strings formed from plaited tendons of the narwhal. The bow has now been displaced by the gun, but most of the men have used the bow and arrow in the reindeer hunts in their younger days, and they can still both manage and make these things. In shooting the arrow is held between the [Н.Р. Steensby.] XXXIV. Medd. om Gronl. 357 forefinger and middle finger of the right hand. The shaft of the arrow is of wood with or without two laterally placed steering-feathers, and to the fore-end of this shaft is lashed a tine from the antlers of a deer, with or without an iron point and also with or without barbs. During our stay at North Star Bay in 1909 a small number of bows with corresponding arrows were made at request by the old Masaitsiak, who was probably one of the few who had never hunted reindeer with any other weapon. As I observed that the length of these bows, which were made by the same man, was different, becoming gradually shorter, | made an at- tempt to get information {regarding the more or less purposeful, established custom for the size of the bow; it seemed to me namely that there must be some principle or rule. Unfortunately this as well as various other investigations were difficult to carry through, owing to the fact that my interpreter from West Greenland was not specially fit for the task. It appeared however, in the first place, that Masaitsiak was quite aware, thal these bows and arrows were not made really for reindeer hunting, but only to satisfy the odd whims of the strangers, so that they did not require to be exactly right, and owing to the scarcity of material he was free to reduce their length. It appeared, further, that the regulation length of the bow was taken from the distance between the outstretched finger-tips of the left hand and a little way beyond the middle line of the breast; its length would be 79—80 cm in Masait- siak’s case. The length of the arrow — excluding the bone fore-part with the iron-point, which did not seem to have any definite regulation length — was indicated by him by bending the left arm at a right angle and stretching the fore-arm and fingers straight out; the length of the arrow shaft would thus be from the inner side of the elbow-joint to the tips of the fingers. One of the arrows he made for me had the right length (42 cm plus 12 cm for the bone fore-part and iron SIM LG 558 point), but a second was too short, because — so he said — he had not sufficient wood. We have here a problem, the solution of which would be of the greatest ethnographic interest. How many pieces do the ethnographic collections not contain, which would prove to be quite valueless types if we knew exactly their previous history? Every one believes himself capable of making an ethnographic collection, in reality it is a highly deve- loped and difficult task, if it is to be done satis- factorily. Fig. 36 is a drawing after a photograph of the authors showing a Polar Eskimo in his kayak; it will be seen that the man sits in an open space, bounded in front by a rounded piece of wood, on which the central part of the paddle rests in rowing. In this figure the paddle is seen from the side, but in fig. 37 it is seen from the surface. On both sides of the middle piece of the paddle are the thinner parts for the hands, about 8 cm long, while the middle piece is ca 48 cm. Further out a leather- strap is bound round both blades, so as to prevent the water which runs down the blade from reaching the hand; the length of the blade itself is ca. 77 cm and the breadth up to 8cm. The whole length of the paddle is about 260 cm and no part of it is made of bone. Fig. 36 shows the harpoon lying in front of the kayak, with the foreshaft turned towards the man; leather thongs hold it down to the kayak. Under the harpoon are the coils of the line, which passes from there to the right of the man and back to the large bladder, which is seen lying behind on the kayak immediately behind the already mentioned small bladder. 359 The large bladder is made from a skin of the fjord seal and the shrivelled up front- flippers of the seal are seen to be still at- tached to the bladder. Under the hind part of the large bladder lies a square wooden frame, the bottom of which is covered by a skin; this frame is thrown into the water and is dragged along 3—4 m behind the bladder by means of a string, which is at- tached to the bladder at the same place as the harpoon line. The speed of the attached animal through the water is further hind- ered by this contrivance. On the figure can be seen some of the 8 strings which are fastened to the frame; above the centre of this the strings are fastened together on one line which passes to the front end of the large bladder. Behind the frame and the bladders is seen the lance, which is held fast under a pair of thongs on the left side of the deck of the kayak. Fig. 38 is a diagrammatic sketch of a Polar Eskimo kayak seen from above; so far as the lengths and breadths are concerned the measurements are in the correct pro- portions AB 5,3 m). The lashings which keep the harpoon and lance in their place are represented at C, D (2 straps bound together at the middle), Ё and КР; abed is the opening of the kayak. K is the rounded wooden piece on which the paddle rests du- ring rowing. С and H are a couple of pieces of bone or wood, on which the har- poon is placed when approaching the prey, 360 for convenience in seizing and slinging it out. In the kayak itself or on the front deck a gun may nowadays also be carried, sometimes lashed to the kayak by a thong so that it should not be lost if it fell overboard. The Polar Eskimos are very careless in their ways of keeping and looking after their weapons. The well known Eskimo bird-dart is not at all used. As mentioned previously, this form of kayak is only in small degree suited for use on the sea. And the Polar Eski- mos for this reason took great interest in the West Greenland kayaks, which the Expedition had brought with it, and a West Greenland kayak which Knud Rasmussen had taken up on an earlier occasion had even already produced an effect, which could be traced in some of the kayaks at Umanark. The open kayak of the Polar Eskimos or rather of the Ponds Inlet Eskimos is more suited for use on rivers than on the sea. The square, open frame is certainly also a relict of the birch-bark canoe, which was only covered over in front and behind. Models of the Canadian birch-bark canoes are to be found in the ‘‘Museum für Völkerkunde” in Berlin and in these the upper deck extends over */srds of the length of the canoe, so that the middle third is open’. That the well of the kayak has become narrower in front, is possibly connected with the fixing of the wooden board mentioned as support for the paddle, by which means the rowing is made easier. The Polar Eskimo kayak described seems to agree well with the figure Low gives of a kayak from Cape Haven south of Cumberland Sound; on the other hand, it differs from some figures gives by Boas? of the kayaks of the Central Eskimos from the southern Baffin Land and Repulse Bay, as these have round wells. In several respects it seems to differ from the 1 ef. А. Byham, Die Polarvölker. Leipzig 1909. PI. X, fig. 2. 2 The Central Eskimo. 6th Annual Report of the Bureau of Ethnology. Washington 1888, p. 486 et seq. 361 river-kayak covered with deerskin, which is used by the Kini- petu Eskimos, an inland tribe on the Barren Grounds, whom А. Р. Low describes as follows’: “The Kinipetu kayak is extra- ordinary in shape. It is long and narrow and quite deep, so that the midship section is almost semicircular. The ends terminate in long narrow points, of which the bow end slopes downward towards the water and the stern end is inclined up- wards. This kayak is so narrow that the combing of the well sometimes projects beyond the sides. Being narrow and cranky, a good deal of skill is required to handle these craft with safety, and accidents caused by upsetting are not uncommon. These kayaks are covered with parchment deerskin, and are the only ones painted [in contrast to the kayaks used by the coast Eskimos on Hudson Bay, in Labrador etc.], various colours being obtained from oxide of iron found in the interior’. This kayak is only used for inland hunting. Low explains that the kayak form of these inland Eskimos is peculiar to them, whereas the natives on the west coast of Hudson Bay, especially the Eivillik Eskimos at Repulse Bay and neighbourhood, have quite a different form of kayak, which is more closely related to the kayaks of Labrador and Baffin Land. This information is not without importance. Further, it seems from Low's description of the Kinipetu kayak, though somewhat general statements only are made, that this kayak form possibly again stands somewhat nearer the small birch- bark canoe; I am thinking here, namely, of the statements re- garding its narrowness and its semicircular section. This information does not quite agree, however, with that given by Е. Boas”, according to which there seems to be greater agreement between the Kinipetu implements and those used by the Eivillik Eskimos. On the other hand, it quite agrees with 1, с., р. 154 et seq. The Eskimo оп Baffin Land and Hudson Bay. Bulletin of the American Museum of Natural History. Vol. XV. New York 1901. 1 2 362 James Anderson’s observations made on his journey in 1855!. He also found that the kayaks were covered by deerskin, and the Eskimos he met with were clothed partly in deerskin and partly in musk-ox skin. Partly from these and partly from other reports? it appears with certainty, however, that there really still lives a tribe of inland Eskimos on the Barren Grounds, which carries on the hunting of the reindeer and musk-ox. The question is thus only, whether these inland Eskimos have once dwelt by the coast and have migrated from the coast into the interior, or whether they have never been in closer touch with the sea, but have always lived in the interior. in the latter case, they are then to be regarded simply as the remains of the original Eskimos before these changed over to the life on the sea coast. Or more correctly, they are in such a case an intermediate stage between the supposed, oldest stage, when they lived as hunters in the birch and pine woods, and the present mode of life on the sea-coasts of the Arctic. They have taken the step from the woods out on to the tree-less tundras and have thus, among other adaptations, been obliged to replace the birch-bark covering of the boat with deerskin. I shall not enter further into these interesting, but still somewhat uncertain problems regarding the early history of the Eskimo culture. I have already dealt with this question in a work”, in which I have come to the result, that the Eskimo culture must have developed on a sea-coast of the Arctic, and I have shown, that the point of origin must probably be sought for on the stretch between Hudson Bay and Coronation Golf.

In the foregoing pages I have endeavoured among other things to show, how the industrial culture of the Polar Eski- mos, solely on the basis of adaptation to the natural geogra- phical conditions, has attained a considerable height, which is expressed partly in their apparatus partly in the ‘culture of the hands”. With regard to the sociology and psychology of the tribe, to the understanding of which the myths, folk-lore and fables collecled and in part published by Knud Rasmussen! will give an essential contribution, [ shall express myself here quite briefly. The high development of individual skill in hunting and hand-craft has led to a corresponding development of intelli- gence in practical regards. So long as a situation merely re- quires jugdment of the natural conditions or of those condi- tions which lie within their practical experience, we can scarcely find more intelligent people than the Polar Eskimos or people with greater ingenuity and powers to get themselves out of a difficult position. This combined with their hardihood makes them incomparable helpers in the polar expeditions. As an example of the Polar Eskimo’s ability to pursue a line of reasoning, I may cite here an answer which Mylius Erichsen received from the angakok Sorkrark to his question: why not a single bear had yet appeared in the neighbourhood ! Nye Mennesker. København 1905. The people of the Polar North London 1908. XXXIV, 24 364 of Agpat late in the year. ‘No bears have come because there is no ice, and there is no ice because there is too much wind, and there is too much wind because we mortals have offended the powers’. When Sorkrark’s practical experience fails, he thus concludes with an anthropomorphism, and he imagined further, that by means of his gut-skin drum and a Shamanistic seance, he would be able to find out, why the ‘‘powers” felt themselves offended, but owing to weakness he was obliged to give up. This example illustrates, if I may say so, the animistic limits of the real comprehension of the Polar Eskimo; they are wider than is the case with many other nature-peoples. On the other hand, their horizon is greatly limited in sociological regards, corresponding to the so primitive nature of their so- cial organisation. Thus I may mention how extremely little connected their notions are with regard to the idea of property. What a man has made for himself is his own property, and the idea that this right of possession can be transferred to another has not developed. In their dealings with Europeans they have, it is true, adapted themselves to a practice in this direction; but cases are constantly arising which show their true feelings in the matter. For example, it is impossible for a European to buy an apparatus of a Polar Eskimo and then hand it over to another Eskimo; the first will never be able "to get rid of the idea that it is his property, and he will believe himself entitled to take the apparatus back, as soon as he does not wish the other to have the “loan” of it any longer. Further, | have hitherto mostly laid emphasis on the purely individualistic traits, which one constantly runs up against among the Polar Eskimos, and which are so much the more striking, as one is not accustomed among the more southerly nature-peoples to meet with such a high individual development in conjunction with so slight a social develop- ment. Naturally the life of the Polar Eskimos is not wanting 365 in social features, but everything has contributed to retard the development of the “society”, so that the tendency to work and live together, which the Polar Eskimos are certainly also in possession of, has never had the chance to develop. Practically the only sort of cooperation or subordinate kind of sociological formation we can talk of in the case of the Polar Eskimos, is the settlement; but as this is constantly on the move, sometimes scattering, sometimes concentrating Fig. 39. Scene from a summer settlement (drawn by the Eskimo woman Tukuminguark). To the left of the tent are seen two persons in conversation; at least one of them is a woman. To the right a Dane is approaching with his hands in his pockets and behind him an Eskimo. 5 dogs fastened to a stone are welcoming the new-comers, and a 6th dog is trying to get up on a depot-pillar with meat on its top. To the left a sledge and on this, Tukuminguark said, her little son sits playing. more or less, this unit is not very constant either. The basis for this periodic meeting together at a settlement is in part relationship, in part the comradeship of the hunt. On the other hand, there is no such thing as true alliances or group- ing according to age, probably on account of the small num- bers and scattered nature of the tribe; nor are any ceremonies or forms known on the attainment of maturity. The feeling of relationship is not small. It expresses it- self, for example, in greater gentleness towards relatives, in 24* 366 contrast to the absence of sympathy and the sharp criticism, which the joke-loving Eskimos display towards everything and everybody not belonging to their own family. The hard struggle for existence has not permitted the Polar Eskimo to become other than a confirmed egoist, who knows nothing of dis- interestedness. Towards his enemies he is crafty and deceitful; he does not attack them openly, but indulges in back-biting; he will not meet his deadly enemy face to face, but will shoot or harpoon him from behind. It is very necessary to remember that these Polar Eskimos, who are so smilingly gentle and friendly, even tactful, on meeting, are by no means ideal. It is only during the hunt that a common interest and a common danger engenders a deeper feeling of comradeship, and this may lead to a few of the hunters of about the same age agreeing to hunt together, journey together and remain at the same settlement, perhaps even if possible live together in the same house. If the natural conditions and the dangerous struggle for existence have prevented the development of a more solid social organisation, they have led on the other hand to a kind of comradeship between the unattached and independent individuals of the male sex. How serious this necessity for comradeship may be, is shown hy an event of recent years. The angakok Kajorapaluk (Peary’s Kyoahpadu or Kyo) was a bad character and a bad comrade, who was always offending the other members of the tribe in various ways; but what was specially fatal was, that he was constantly lying and deceiving them with regard to the hunting. Sometimes he amused him- self by warning them of bad hunting and consequent famine, in order to frighten them, sometimes he told them that he had seen here or there, for example, the white whale or walrus; but it was always falsehood. At last it became too much for them; it gradually became the common feeling of the tribe, that it would be best to get rid of such a troublesome indivi- dual. He was killed by Uvdloriark and Masaitsiak, two of the 367 best men of the tribe, and the latter married the dead man’s wife, whom he lives with till this day. The ‘public opinion” has very great weight among the Eskimos, and the individual is obliged to give way before it. It maintains the unwritten laws or regulations, which form the basis of the training and attitude towards others of every Polar Eskimo. These fundamental laws are in the main the same as rule among other Arctic Eskimo tribes. As regards West Greenland these laws have been discussed by H. Rink, and in a similar manner as he has done we can formulate some of the principal rules governing the social life of the Polar Eskimos. (1) The requirement that no man except in case of natural weakness can evade making his own living, and he is still less permitted to interfere with others or prevent them from making their living. (2) The rule that no one can establish himself in a settle- ment without the permission of those already settled there. (3) The practice that the spoils of the hunt, when they are not small, for example not less than a fjord seal among the Polar Eskimos, are divided partly between those taking part in the hunt, partly between the natives at the settlement, and according to definite rules. In times of want the division of the spoils and of the depots is made even more equal, but at such times any person who is disliked runs the risk of being excluded from receiving help. The man that cannot completely make his own living, owing to either bodily or mental shortcomings, cannot obtain a wife and thus is unable to reproduce his kind. Similarly a hunter who has lost his strength in one way or another, will also as a rule loose his wife, as she will leave him and seek for a better provider, if any such will have her. There is no doubt that this natural selection plays a specially great part in a small hunting community like the Polar Eskimos’ and it is 368 very probable, that one of the reasons why the Polar Eskimos are so few in numbers is this, that their hunting life demands so much strength and intelligence and requires such a high grade of constant training, that only the very best can persist in the struggle for life. A related reason for the small numbers however is also the comparatively great difficulty of obtaining objects of food, which might serve as “тезегуе” in times of want; thus in the earlier days especially the Polar Eskimos to a very great extent lived on the verge of starvation, and their Fig. 40. Drawing by the Eskimo woman Arnaruniark, representing the interior of a house, with 4 persons sitting on the main platform; the two outermost are sitting close to the side- platform on which the lamps are indicated. The window is drawn in front, in the plane of the paper. To the right of the house is a kneeling person busy stealing meat from a depot, whilst his comrade is standing and keeping watch, so that no one should come and surprise them in the act of thieving. lore and stories bear witness, that families or groups were not so seldom in want of food or died from the frost. On such occasions cases of cannibalism have arisen, probably af- fecting in the first instance the old and the feeble. Marriage is regarded purely as a condition of property, and chief weight is laid on the woman being able to work as also to bear children. In cases of infertility the marriage bond is very loose and will in many cases be dissolved by discarding the woman. Special weight is laid on the woman being able to bear the male children or the future hunters; but the scarcity of women at the present time has led to their 369 having a more protected position than before. It has further led to the woman being married at a much earlier age than previously, even so early as 12—13 years, though she is said not to develop appreciably earlier than the European woman. On the other hand, the men do not marry before they are fully developed hunters, that is, about twenty years of age or more. At present there is said to be only one man in the tribe who has 2 wives. The well-known Eskimo system of exchanging wives is carried out under festive ceremonies and is also a custom of practical importance; for example, if a man wishes to undertake a journey and his wife for one reason or another is unable to accompany him, the matter can be ar- ranged by making an interim exchange with another man whose wife has no such hindrances. Nevertheless, the Polar Eskimos are to be reckoned among the nature-peoples of good morals; a woman is judged very strictly if she gives herself away to any other but her own husband, unless he commands her to do so, and in their relations to strangers it is exceptional that a man offers his wife in order to gain something by it. When the Polar Eskimos are face to face with cases in which the settled ‘“‘public opinion” cannot at once decide the matter, or where a difficult case of sickness or want arises, the “‘angakok” is called in to clear up the problem by exorcism. In religious matters the Polar Eskimos relies exclusively on the ‘‘angakok”, who by his art and genius and his conjura- tions is supposed to make himself master over the powers which rule over life and death, sickness and strength, weather and the animals of the hunt. Knud Rasmussen’ once obtained a characteristic answer from a Polar Eskimo: ‘‘We do not be- lieve in any God as you do. We do not all understand the things that are hid, but those who say, that they understand, them we believe in. We believe in our ‘‘angakut” (plural of 1 Nye Mennesker. pp. 136—137. 370 angakok), in our conjurers, and we believe in them because we wish to live long, and because we do not wish to run the risk of famine. We believe for the sake of our lives and for the sake of our food. If we did not believe in our priests, the animals we hunt would not be apparent to us; if we did not follow their advice we should become sick and die”. Whilst in secular matters a chieftainship or a differentiated social organism has never developed, the Polar Eskimos in religious regards come under a leadership of developed Shama- nism and are thus in so far a step further advanced in religious than in sociological matters. This is certainly connected with the fact, that they have to struggle almost exclusively against nature and the misfortunes arising from the forces of nature, whereas they have not known what it is to be obliged to fight for themselves and their hunting-districts against hostile tribes. The considerable communication which has existed be- tween the last generations and expeditions has not failed to influence the Polar Eskimos in regard to their views of the world and the hidden powers. They now know that there are many and densely populated lands in addition to their own. And they no longer believe so directly in all the spirits, ‘‘tor- narssuit”, they ascribe to all the localities — house-floor, space behind the skin-walls, the lamp, house-entrance, refuse-heap in front of the entrance, the fells, the sea — from which they have special opportunities of receiving impressions and moods, or in other words, to nearly everything for which they have names. In earlier days they were afraid of these spirits and believed that they had no good-will towards men. Now they are somewhat more superior in these matters, though the be- lief in spirits is by no means extinct’. I am so fortunate as to be able to give an actual illus- tration of the more open mind with regard to these matters 1 cf. Knud Rasmussen: Nye Mennesker, p. 148. 371 at the present day. Fig. 41 is reproduced from a drawing due to the collaboration of Arnaruniark and her husband Samik. Arnaruniark first drew a fully loaded sledge, with 6 dogs har- nessed to it, meaning that it was her husband who was return- ing home from a successful hunt. Then Samik himself drew a “‘tornarssuk” in between the traces of the dogs, meaning in jest that it was harnessed to the heavy sledge. Samik himself is seen standing with the whip in his outstretched right hand ready to strike at the ‘“tornarssuk”, but Arnaruniark standing Fig. 41. The “tornarssuk” fastened to the sledge (drawn by Samik). behind with the child in the amaut takes hold of his arm to keep him back. After obtaining this explanation from Samik I asked him, if he had seen a ‘‘tornarssuk”. He replied no, he had never seen him, but he had often heard him among the fells. It may be remarked expressly, that both this and the other figures reproduced, with hardly any exception, were not drawn by request; the subjects were chosen quite freely by the Polar Eskimos. After I had got one person to make a drawing, there were many willing to do so, and I only required to give 372 the one or the other a drawing-book and a pencil for a day, and then have it returned with a couple of drawings of their own making. Some of them could sit for hours and draw with a seriousness, which showed that the work interested and oc- cupied them. Others I saw asking the opinion of the sur- rounding Eskimos, whether this or that position was quite correct, whether the arm was held so far back on swinging the whip and so on. Most of the drawings reproduced here have been reduced. The explanatory text is based on informa- tion, which I sought in every case to obtain as fully as possible by means of the interpreter. In the foregoing I have mentioned the feeling of kinship, the comradeship in the hunt, the public opinion and institution of the angakok as the most important, active forces in the primitive Polar Eskimo community. Lastly, a couple of prac- tical statutes were mentioned. But there are others factors, however, which contribute to form the ideas and proceedings of the Polar Eskimos. These are the stories and fables of the tribe, which it has in common with other Eskimo tribes, but in well-marked characteristic variations to an extent which has not yet been sufficiently investigated. Some of these stories and fables are purely descriptive and give an answer to one or other question, for example, the creation of the world; but others contain a rule of life or sketch supernaturally capable hunters or great angakoks, who may stand as examples or types worthy of imitation. Lastly, there is a number of traditional customs and forms, which have a regulating and determining influence in many conditions of life. There are somewhat complicated customs with regard to confinement and burial, and there are occasions which require the prohibition of definite kinds of food and certain actions. On the other hand, there are no special cere- monies with regard to marriage. Further, amulets and con- juring formulae are used in certain situations. In regard to 373 these things the Polar Eskimos do not exact the precise, well- founded understanding as in the case of the actions which have to do with earning their livelihood. They are carried out simply because they have been prescribed in this way in the old traditions, the origin of which is lost in the dim past. We touch here on an interesting point, namely, the rela- tion between their absolute, social freedom on the one side and their dependence on tradition on the other. The Polar Eskimo is his own master in everything he does, and he per- mits no interference from others. He will only take up some- thing new when it has been shown to him in such a manner, that his desire to imitate has been roused. On the other hand, if he is accustomed to do anything, he continues to do it owing to man’s natural inertia, even after the rea- soning has been forgotten. Even after such a tradition has lost its practical significance, indeed after it has come into conflict with practical interests, it may still be retained as a survival or remnant. The cultural history of the Polar Eskimos has in fact shown examples of such survivals, which stand in direct con- flict with the interests of the tribe. I may recall here firstly, how they had earlier failed to hunt the reindeer, though their neighbourhood was sometimes teeming with these animals, which for most other Eskimos constitute such an important part of the hunt. Further, how they did not fish for the salmon, though they had the opportunity of observing every year, at least in one lake at Etah, the great abundance of this fish, which is also of importance for most other Eskimos. The same thing applies to their ignorance of the kayak. There can be no doubt that these cultural shortcomings must be regarded as survivals of traditions from the time that the Polar Eskimos lived under conditions, when the hunting of the reindeer and the fishing for salmon had to be given up for natural reasons. 374 How the folk-lore of the Polar Eskimos, their fables, forms, customs, amulets, stand in relation to corresponding pheno- mena among other Eskimo tribes, and how far their origin can be traced back to other cultures and races of people, need not be further discussed here. I may simply mention, that in various cases we can still detect sometimes a natural instance of adaptation, sometimes a simple analogy, under the influence of which the custom has been formed. Reasoning by analogy seems especially to play a great part, a superficial point of resemblance becoming determinative of the whole matter; for example, when the women make up the soot scraped from the bottom of the cooking-pot into an amu- let sewed into their neck- band (Fig. 30), following the reasoning, that lamp-soot is Fig. 42. Two women in conversation and a dog; stronger than the fire itself, scene from the settlement (drawn by the Eskimo woman Alakrasina). The woman to the left has the hood of the outer pelt drawn up over the head; the woman as the fire has not been able to destroy the soot, and con- to the right has a child in the ‘“amaut” sequently that the lamp-sootis and the loose, helmet-shaped hood on x а the strongeststuff in the world and able to give protection. The method of reasoning of the Eskimos gives us the impres- sion of being very superficial, because they are not accustomed to retain what we call a definite line of reasoning or a single, isolated subject for any length of time; their thoughts, namely, do not rise to abstractions, or logical formulae, but keep to pictures, of ob- servation or situations, which change according to laws we find it difficult to follow. Their ability to draw is evidence of the nature of this mode of thinking, as also their power of their own accord to choose subjects for reproduction, in spite of the fact, that they never 375 draw, either on their implements or on natural objects. The choice of subject does not seem to offer them the least diffi- culty; it seemed to be natural, that as soon as they set the pencil to paper, some one or other favourite mental picture, which was extraordinarily clear to them, should begin to ap- pear. In agreement with this also, it was chiefly the women who drew house-apparatus and scenes from the settlement, whilst the men chose to represent animals and scenes of the hunt. One motive which both sexes have shown a predilec- tion for, is a woman with a child in the ‘‘amaut”. Samik has even drawn in one figure (fig. 43) a pregnant woman, who at the same time carries a child in the amaut. For Samik this situation represents the acme of desirable fertility. These drawings of the Polar Eskimos, a- mong whom drawing is not a traditional exer- cise, but is the occasional unfolding of a latent talent, the presence of which is connected partly with the special mode of thinking, partly with = ing 15. 45. the “culture of the hands”, may be compared Pregnant woman with child in the “amaut” (drawn by has been practised for generations, so that the Эа. with drawings of nature-peoples, where drawing art has already come under the influence of tradition. As ex- ample the bushmen may be cited. We then see that there is no difference in the power to conceive and reproduce, which the Polar Eskimos display with regard to animals and to people. These are reproduced in a manner which bears witness to an almost equally sharp power of observation in both cases. This seems to show, that the well-known tendency among other hunting-peoples, accustomed to draw, to reproduce animals better than men, is not due to the lack of observation of men, but rather on the contrary to the fact, that the man’s figure being easiest to recognize is the more readily subject to sim- plification. Just as with the Polar Eskimos, the nature-peoples 376 do not draw in order to attain any high artistic level; they are satisfied when it can be seen what their intention is. With regard to the animals, the Polar Eskimos seem to share the view prevailing among nature-peoples, that there is no great line of division between the life and intelligence of men and animals. As Karl v. d. Steinen expresses it, man is rather to be regarded as primus inter pares than as an exist- ence which is elevated high above or beyond ordinary living things. The most intelligent of all the animals is the bear, and the soul of the slain bear is also the most dangerous to men; certain rules of precaution must therefore be taken, to prevent the bear from returning to take revenge. These hunt- ing customs are most developed and most comprehensive in regard to the bear, but corresponding ideas exist to less extent in the case of other animals. The views and feeling of the Polar Eskimos with regard to life are not refined by any kind of poetry or artistic tenden- cies. If the translations of their folk-lore and tales into a European language seem to give an impression of poetry, it is we who read this into them. For the Polar Eskimos life is deadly real and sober, a constant striving for food and warmth, which is borne with good humour and all dispensations are accepted as natural consequences, about which it is of no use to reason or complain. Death also is accepted with the greatest fortitude and occupies their daily thoughts to an extremely small extent. As already mentioned, the struggle for existence has been made easier for the Polar Eskimos in our days owing to the improved apparatus, even though it may still happen, as for example in February 1903, that a considerable number of individuals may perish — in the case referred to, half a score perished on a journey over a glacier at Nerkré. The tribe now has almost a flourishing appearance, and we now find, cer- tainly in consequence of this greater prosperity, that the use- 371 less old people and cripples are maintained by the tribe year in year out. In another matter, however, the conditions have not permitted them to display humanity; this is in the case of small children whose mother has died. They are killed by the father, as he finds it impossible to obtain nourishment. for them, unless quite exceptionally there may happen to be a woman able to foster them in the settlement. The Polar Eskimos have very little notion of time. No one knows his own age. Even the age of the children can only be given by the parents after they have sat down and calcu- lated how many winters have passed since the child was born. Except for the light period, the year is divided according to the moons, each of which has its own peculiar name. During the light period it seems to be chiefly the migration of the birds which gives definite points for the determination of time. The days passed, е. 5. on a journey, can only approximately be given according to the number of times they have slept. Shorter periods may be indicated, for example, by showing how great a distance the sun will travel across the sky or, if the sun is not to be seen, would travel in the time thought of. But we must remember here, that these statements are chiefly made in conversation with Europeans and in answer to their quest- ions; for the Polar Eskimos themselves, the reckoning of time has not the slightest importance. Another matter is, that the change of the seasons seems to have a fairly considerable influence on their temperament and moods. А peculiar form of hysteria, more frequent among women than men, is said to be strikingly common late in the autumn, when the winter darkness is just coming on. Such attacks, which last for some few minutes to about half an hour, may however also appear at other times of the year, caused by a sudden fright or other unusual mental shock. In July 1909 I was witness of such an attack in the woman Inadtliak (fig. 30). It lasted 25 minutes. She sat on the ground with 378 the legs stretched out, swaying her body to and fro, sometimes rapidly sometimes more slowly, from side to side and tortuous- ly, whilst she kept her hands comparatively still and only now and then moved her elbows in to her sides. She stared out in front of her quite regardless of the surroundings, and sang or screamed, occasionally changing the tone, iah-iah-iaha-ha.. .; now and then she interjected a sentence, е. 5. that now the Danish had at last come to them, and again the great happi- ness this gave her now in the glad summer-time and so on. Her two small children sat and played about her, whilst the members of the tribe scarcely looked at her during the attack; they seemed io be very well acquainted with such things. She recovered quite suddenly and only some hectic, red spots on her cheeks indicated anything unusual. Without so much as looking about her or betraying a sign of anything unusual she began, literally in the same moment, to give her youngest child milk and then went quietly on to chew a skin. Accord- ing to Knud Rasmussen’s experience this attack was com- paratively mild; in other cases the sick person may have a lust for destruction, and men frequently become very dangerous to their surroundings. The songs of the Polar Eskimos strike one as being very monotonous especially in the beginning, but they improve on closer knowledge, and according to Chr. Leden! they are of very considerable musical interest from the historical side. The rule is, that every man or woman who has the ability to sing — for there are also unmusical Polar Eskimos, just as there were a few who said that they had no notion how to draw — themselves make up the melodies or ‘‘songs without words”, which they sing. It is the exception for any one to sing the melodies of others. I shall not express any opinion here as to the difference between the songs of the men and the women; 1 On p. 267, line 12, Chr. Refsaas should also be Chr. Léden. 379 both are without words, but now and then a phrase may be woven into them. In regard to voices, there is a great difference between the roaring, open-air voices of the men and the thin, somewhat soft speech and tones of the women, which speak of adaptation to the business of the house and marriage subjection. The principal time when they sing is during the dark period, and the real singers are the angakoks, who sing to the accom- paniment of the beating of a small stick on the frame of the gut-skin drum, which is of the same kind but on the whole smaller than among other Eskimo tribes. In the beginning of August 1909 I was present at an actual musical entertainment at Umanark given by two angakoks, Masaitsiak and Ajorsalik. At midnight the sun had already begun to go down behind the mountains on the north side of Wolstenholm Sound, so that there was a couple of hours twilight. On a night of this kind Napsanguark had invited his kinsmen to a feast consisting of a rotten seal, which had been caught on the spring-ice and had since then lain in the depot to become rotten in the course of the summer. In front of Napsanguark’s tent a sledge was set up on end, resting on the uprights, and a skin was hung between the tent and the sledge, so as to give some shelter against the coolish wind from the west. The seal was laid on the ground right in the corner between this skin and the front of the tent. It had just been cut open and the blubber had been removed and placed on one side. The flesh lay swimming in the blood on the skin and in the opened abdomen. The men stood or sat round about, and now and then they reached forward to the food and cut themselves a lump of the rotten flesh and stuffed it into their mouths. The women and children, who kept mostly inside the tent, also came forward now and then to obtain their share, and the children especially looked quite wild as they ran about with their faces all covered with blood. XXXIV. 25 380 The smell of the rotten flesh was soon very unpleasant, but one quickly became accustomed to it. Laughter and cheer- fulness prevailed. After the feast was over, Knud Rasmussen was successful in persuading Masaitsiak and Ajorsalik to sing. They placed themselves inside the densely packed tent, opposite one another on the floor in front of the opening, and began their preparations. But these took up some time, as they were both obviously nervous. Like European virtuosi they complained that there were various things which prevented their doing themselves justice. It was too light and there were too few people, said Masaitsiak. According to European taste there were already far too many in the small space; but the Eskimos like best of all to pack themselves so close together on the platform and the floor in front, that one can hardly move. At last Masaitsiak began to sing, beating the drum at the 9 same time: ‘...iah-iah-iah-ah-iah-ah-aha ...”, all still without a word, and now and then the whole company joined in with some tones as chorus. He kept his eyes closed the whole time, and Ajorsalik later did the same thing. The expression of the face gradually altered to the mood of the song, and the face appeared to be turned more and more upwards. At the same time he began to dance. This means, that the soles of the feet remained firmly planted at the same spot, but the knees bent and the body swung and turned on the hips. The different movements were neither strong nor violent, and they were com- bined, with constant changing of the manner, almost like the few tones of the song. The drum was used at the same time, being held in the left hand and beaten with more and more force. So long as Masaitsiak sang and danced, he gave himself up to it entirely and his whole body and all his movements expressed the feeling of the song and dance. Ajorsalik stood the whole time in front of him with a small stick ca. 15 cm long in the hand. At the moment when Masaitsiak was about 381 to end his first song, Ajorsalik held up the stick between the thumbs and forefingers of both hands, perpendicularly in front of his face, and shook it rapidly from side to side with the upper (right) hand, as if there were something that should be shaken loose. As if waking up, with a gasp for breath and quick nod of the head, Masaitsiak returned from his transport to ordinary life, both he and Ajorsalik crying: “... waeih-waeih- eh-eh...”. This performance was repeated at the end of every song by one of the singers. Masaitsiak sang again 3 or 4 times before Ajorsalik began and his condition of ecstasy increased each time. The song became stronger and the movements more violent and more rapid; one quite forgot that it was the old, simple man whom I had so often seen sitting and dozing over some hand-work or another. Ajorsalik’s songs were feebler and his dancing and beating of the drum much less imposing. He also sang 4—5 times, and then Masaitsiak began again, and in this way thev relieved one another several times, until — not the sin- gers, for they can keep it up for nights, once they have come into the spirit of the thing — but the listeners, especially the Europeans, became tired and got them to break off.

Daring our stay at North Star Bay I also made some anthropological observations and measurements, in which 1 followed the methods taught by Professor F. v. Luschan of Berlin. _ As I only met with a small portion of the tribe, however, — partly because so many of them were with Peary in the Polar Sea — I shall not enter here upon a general account of the anthropology of the Polar Eskimos, but restrict myself to some of the main points in the observations along with the photographs taken by me. At this moment also, there is less reason for going too deeply into the subject, as the extensive work on the anthropology of Greenland prepared by C. M. First and F. C. C. Hansen is just about to be published. When we get over the first impression of distaste towards their dirtiness and less pleasant smell, the Polar Eskimos have in reality a pleasing exterior and are specially remarkable for their well-proportioned structure and fine, small hands and feet. Those I met were on the whole small, but there are not a few men in the tribe who are above the average height. It is said that those who are descended from the Ponds Inlet Eskimos belong to the tallest in the tribe. The men especially are very muscular, but as both the men and the women must be con- sidered as well-covered, their musculature is not very pronounced or marked. The health seemed to be extremely good. From the racial standpoint the first impression one obtains of the tribe, when one comes from the more southerly West 384 Greenland, is almost one of surprise. For it seems indeed to be quite a different race. In West Greenland we are accustomed to regard the Eskimos’ racial character as distinctly ‘“Mongolian”, and up here the Mongolian type is little in evidence in com- parison with another type, which may provisionally be called “Indian”, in spite of the fact, that it also occurs in North-Asia and that it is not so marked as in the traditional, extreme Indian type. It is a type which is much less separated from the European than the Mongolian is, and I have a very strong impression that the reason why the existence of this type in West Greenland is almost entirely overlooked is, not only that the Mongolian type is perhaps predominant, but also that these non-Mongolian individuals have been unintentionally considered as mixed-European more than they really are. The Polar Eskimos resemble more the Central Eskimo tribes on the mainland, for example, the Netchillik Eskimos!, than the West Greenlanders to the south. Probably the natives in the Upernivik district form a transition, however, as is pointed out by Soren Hansen”. The same author” also shows, that the so-called Mongolian racial characters, namely, the low nose, oblique eyes, flat face, broad and big cheek-bones etc., are more prominent in the women than in the men of West Green- land. Exactly the same condition is found among the Polar Eskimos. The colour of the skin is not so variable individually as is the case in West Greenland. This applies for the rest to practically all characters and is evidence, that the tribe is un- mixed or at least only in very little degree mixed with European elements. Even in the generation which is growing up, there are but few exceptions to this rule. The skin has always a yellowish ground-colour, but this may appear in various modifications in 1 ef. Roald Amundsen, Nordvest-Passagen. Kristiania 1907. 2 Bidrag til Vestgronlandenes Antropologi. Meddel. om Grønland. Vol. 7. С. 385 the same individuals. On the covered parts of the body it is as a rule yellowish-white, whereas on the face and especially on the cheeks it changes over to reddish-brown or copper- coloured. To the touch the skin is soft and somewhat oily. The so-called ‘‘Mongolian spot” is present; I observed one 6 cm long and 3cm broad on a 13 months old child; it lay over the sacro-lumbar region along the vertebral column with a slight asymmetry to the right side. All the individuals have dark-brown or brown eyes. In a single case the colour of the eyes was nearly brownish black, and in one older individual the iris was somewhat spread out, so that the colour was almost light-brown. The opening of the eyes was in most cases fairly even, but in several it could be noticed, that the upper eyelid descended very far down at the inner corner, so that this curved downwards at a sharp angle. The whole opening of the eye might thus appear somewhat oblique, though it in no case attained the most distinct form of the oblique Mongolian eye. The colour of the hair did not differ appreciably in any case from the pure black. Even the old Krulé only had some few scattered gray hairs. The hair is smooth and coarse, but with a tendency to be slightly wavy. It grows strongly and in quantities, and no tendency was observed to baldness. The early loss of hair, which the West Greenland cause by their tightly bound hair-top, does not occur among the Polar Eskimos, as the hair is here worn more loosely. One woman, the young Arnanguak, was an exception in having such short hair that it could not be bound up in “chignon”, but hung loose. The greatest length of hair I observed in any of the men was 48 cm; the rule was about 40cm. There was but slight growth of a beard, and this was further reduced by the habit of pulling out the hairs of the beard, as the ice which forms in it in winter is extremely troublesome and dangerous. The faces are broad and are chiefly characterized by the 386 strong cheek-bones and the broad, muscular lower jaw. The length of the face is here measured from the root of the nose to the chin; but if we consider the whole length of the face from the beginning of the hair to the chin, its form becomes on the whole a broad oval. The painter Moltke’ states, that they have ‘‘smooth faces. The features are like those of a child. The lines quiet and round. It is as if a smoothing hand ‘‘has passed over them” and thus produced a beneficial peacefulness and greatness in the lines — but also sometimes taken away something of the character”. The form of the nose is fairly constant. The root is not specially depressed and the nose itself projects distinctly forward and has a straight and comparatively long ridge. There is not seldom an inconsiderable prominence, which gives the nose a tendency to be aquiline. The tip of the nose may be a little hanging. The breadth is not great, but in the case of a few women with the broadest faces, e. g. Inadtliak, the nostrils were somewhat distended, so that they appeared slightly broader than high. The teeth are fine and strong and form regular rows almost always. It is well-known how they are greatly worn down, and it is a common view among anthropologists, that the woman's skull can be distinguished from the man’s among the Polar Eskimos by the fact, that the teeth in the former are most worn, due to the work of chewing skins done by the women. It is quite possible that the women’s teeth become on the whole somewhat more worn than the men’s in the course of time; but that the difference in the amount should be so great and obvious, that we could use it with any certainty to distinguish the sexes, I think I can safely deny. The men certainly do not chew skins; but they use the teeth for so many different kinds of work and almost always À Mylius Erichsen og Moltke, 1. с., р. 592. 387 with hard materials, that their teeth have good opportunities of becoming worn. Both in the men and the women the inci- sors are more worn than the molars, and of the latter the first two molars are often the most worn. In the old Masaitsiak the front teeth were so much worn, that the new growth of dentine in the pulp took up a great part of the plane, worn surface; on the molars both the cusps and the hollows were worn, so that all the enamel had disappeared except along the edge. According to the scale set up by Broca for degrees of wornness, these teeth were thus in the 4t* or extreme stage. In the old woman Krulé the stumps remaining did not show any greater degree of wornness than in Masaitsiak. In the 50 year old woman Kiajuk the front teeth were worn down a good deal into the pulp; the first molar teeth were in the 3 stage, as the chewing surface was just worn level; on the wisdom tooth, however, the cusps were not yet worn. In the ca. 35 year old Samik the pulp could be seen in the front teeth, and the cusps were already worn down on the molars. In the ca. 30 year old woman Tukuminguark the pulp was not yet bare in the front teeth, and the molars had not yet been worn quite level. In the scarcely 30 year old man Manigssok the pulp of the front teeth could already be seen, whilst the molars were perhaps a little less worn than was the case with Tukumingu- ark, who was about the same age. In the 20 year old man Miterk facets had just begun to appear on the front teeth, but distinct facets had not yet been worn on the enamel of the molars. The unmarried girl Arnanguak, who was ca. 16 years old, was at exactly the same stage, whilst the ca. 18 year old, married woman Akutak also had distinct facets on the molars. Thus, individual differences certainly occur in the amount the teeth are worn, so that it is impossible to base general rules for the wear of the teeth in men and women on so few examples; but I think that the above observations are sufficient to prove my contention, that the teeth of the men are also greatly worn. 388 The outer ear is fairly small in the Polar Eskimos and symmetrically rounded. The lobe is in some cases faintly indicated, but is wanting in most, so that the lower margin of the ear is directly attached to the head. The so-called Darwin point is but little apparent. The form of the skull is far from being subject to such great variations as would be the case in Denmark in a similar number of individuals. The differences occurring are not so great, that they cannot be regarded perhaps as variations of one and the same typical form. This form is characterized by a narrow, somewhat weakly arched forehead, and by a rising crown which furthest back slopes down towards the occipital bone, which is somewhat prominent. It is a form which greatly resembles the common, long-skull form in Europe, and the breadth-length indices found are also evidence of distinct doli- chocephaly, which for the rest was already well-known for the Polar Eskimo skulls. It is also the same form which by some anthropologists is named the palæasiatic. Apart from pulling out the beard, no kind of deformation occurs. Nor is it the custom or use to tattoo. Only a single one of the persons observed had tattoo markings. This was the woman Tukuminguark who by means of soot, thread and a needle had produced some few marks on her skin. Thus she had 4 quite small spots in a row on the left forearm. On the upper part of each breast she had a couple of larger, pa- rallel streaks, but the operation was only to some extent suc- cessful on the left breast. On asking why she had tattooed herself, she only returned an uncertain answer, that she had seen something of the kind. This has probably been among the last-living of the Ponds Inlet immigrants, in the mother tribe of which tattooing is a traditional custom. Tukuming- uark’s few, casual and quite formless tattoo marks are thus to be regarded as an unorganised offshoot of an organised tradition. 389 The following table brings together some of the principal anthropolugical measurements on the men and women. The first three columns give respectively the total height, the height in a sitting position (measured from the board sat upon) and the spread of the arms in cm. The two following columns give the length and breadth of the head in mm, from which the index cephalicus has been calculated and given in column 6.

VINE: It was in the year 1818 that the Polar Eskimos first entered into the light of history, and important and interesting changes in their culture have occurred since that time. As the years which have been of special importance for the cultural history of the Polar Eskimos, during the hundred years that have nearly passed, may be named ca. 1862—1863, 1891, 1904 and 1909. At the date mentioned in the sixties the visiting Eskimos from Ponds Inlet taught them the use of the forgotten apparatus the kayak, the bow and arrow, as also the method of fishing for salmon. 1891 was the year of Peary’s first visit. In 1904 a Danish expedition showed them the way over the ice of Melville Bay, and since then the Polar Eskimos annually make trading visits to the Danish trading posts in the district of Upernivik. In 1909 a permanent Danish Mission Station was settled in their country. The history of the Polar Eskimos before 1818 is shrouded in the deepest mystery. Where did they come from? What other Eskimo tribe is their nearest kin? From the West Greenland Eskimos they have been separated geographically and culturally, and they seem to be so even in regard to physical type. The attitude of the two tribes towards one another, which has been partly one of avoidance partly of direct hostility, also shows that they have not maintained any visiting or family relations with one another throughout the years, but that they have ignored one another’s existence if they chanced to meet on the ice of Melville Bay. 393 The Polar Eskimos are at the least just as different from their nearest neighbours on the other side of Baffin Bay, the Ponds Inlet Eskimos, and it is quite impossible to think, that they could have been directly transplanted from North Baffin Land to Smith Sound. In addition to differences in apparatus and dress we have also the evidence that the Polar Eski- mos were not reindeer hunters. In Baffin Land the reindeer hunting is of very great importance, and the Ponds Inlet Eskimos have also always been keen hunters of this animal. When Me Clintock met Kridlarssuark and his little band on the east side of North Devon in 1858, the only thing they had to complain about was that there was no reindeer in that country. To this must be added, that the nearest route from the Ponds Inlet district to Smith Sound, namely, along the east coast of North Devon and Ellesmere Land, is not of such a nature, that it specially tempts the Eskimos to migrate. Kridlarssuark’s migration is certainly a typical Eskimo migration in regard to the mode of travelling and the period of time used, but it is quite otherwise in regard to its motive. He and his band did not journey because new hunting-places enticed them further and further away, but — as is expressly stated — be- cause they wished to seek the people the whalers had spoken about as living further north along the coast, of whose existence also they certainly had seen material signs, when the whalers came to Ponds Inlet after visiting Cape York a short time be- fore. The route followed, along the Ellesmere coast, is namely not the least inviting to the Eskimos, as has already been mentioned in this paper. The unfortunate fate of the returning Ponds Inlet Eskimos in their attempt to get back the same way, is indeed also witness that the country is not favour- able to human life. Nor do there seem to be any ruins of Eskimo houses on the east coast of Ellesmere Land, from the mouth of Jones Sound towards Cape Isabella, except 394 some few more recent houses, which are said to be known to the Polar Eskimos as having been built by Kridlarssuark and his party. Any group of Ponds Inlet Eskimos that passed over to North Devon simply for the sake of hunting, would certainly not be enticed northwards along the east coast of Ellesmere Land, but would go westwards along the coasts of Jones Sound over to the west side of North Devon and Ellesmere Land, where plenty of musk-ox are to be found; an example of this was obtained by Boas? from an Eskimo woman, whom he met at Cape Kater. She had been with an Eskimo band, which had passed over the ice-covered North Devon on sledges and on to the south-west part of Ellesmere Land, which is called the “Umingman Мипа’” or the musk-ox land, where it is said they even found some natives. For the rest, there is still the belief among the Ponds Inlet Eskimos, that a musk-ox hunting Eskimo tribe lives up in these regions, a belief, however, that later expeditions have shown to be incorrect for the present time. Further, it is known that the Ponds Inlet Eskimos some- times journey to North Somerset to hunt the musk-ox, and that this journey may then extend over the Barrow Strait to the south-west coast of North Devon”, This last direction re- presents, I think, an old and original route for the expansion of the Eskimos. From North Somerset it goes straight north to the west coast of North Devon, right across the north- westernmost part of this island and further north along the west coast of Ellesmere Land as far as Bay Fjord, where one route goes eastwards overland to Buchanan Bay and Smith Sound, whilst another continues northwards up to Lake Hazen in the interior.

Low. 1.6. p. 57 et seq: 395 mere Land! has been made known by Gunnar Isachsen*?, who took part in the Fram Expedition under O. Sverdrup. In agree- ment with Е. Boas” Isachsen considered that the main route went from Ponds Inlet over the eastern end of North Devon and from there along the north coast of this island; but I am of the same opinion as H. G. Simmons‘, that this route is certainly only used exceptionally. In using the word “route” I must however remark, that this does not mean a definite, measured line of migration. An Eskimo band in pursuit of the musk-ox will direct its course according to the distribution of the animals and will only be tempted to move by richer hunting grounds; but the distribution of the islands and their position in the Polar Archipelago is of such a nature, that the main result of the migrations is, that the Eskimos tend to go in definite directions. The starting- points will be on the one hand the northern Baffin Land, where for the rest it is the lines of migration of the reindeer, which — in addition to the coastal ice and the voyages with the women’s boats — determine the migration routes, and on the other the north-eastern Barren Grounds themselves. And I imagine, that the oldest migratory groups went out from this last-mentioned region and from there followed the east coasts of Boothia Felix and North Somerset, where ruins on the coasts are evidence of earlier visits of the Eskimos. With regard to these ruins of houses and other remains of earlier Eskimo settlements reference may be made to W. Thal- bitzer’s chart”, where their occurrence is indicated. In agree- 1 I use this name to indicate the whole of the large island lying to the NW. of Greenland. * С. Isachsen, Die Wanderungen der östlichen Eskimo in und nach Gronland.

Boas, Ueber die ehemalige Verbreitung der XXXIV. 26 396 ment with the distribution of the ruins, I have indicated on the accompanying chart, where the distribution of the musk-ox is given after А. Сб. Nathorst!, the main route along which the Eskimo bands in pursuit of the musk-ox may be considered to have been enticed further and further away from the American continent. Some have gone westwards along the south coasts of the Parry Islands, but the main body has gone up to Elles- mere Land, and there is now — after that the Danish ‘Dan- mark” Expedition under Mylius Erichsen has proved the occur- rence of Eskimo remains right up to the Peary Channel on the north coast of Greenland — no ground to doubt that they have continued their journey northward round Greenland to the north-east coast. For the rest, G. Holm long ago maintained this migration north round Greenland, and later it has been supported by C. Ryder and G. Amdrup on the basis of observa- tions made on their expeditions respectively to Scoresby Sound in 1891—92 and to the coast between Angmagsalik and Scoresby Sound in 1898—99 and 1900. As further support for the view, that these North-East Greenlanders have been musk-ox hunters, we have the follow- ing information, which I have received through the kindness of Мг. С. В. Thostrup, who took over the ethnological investiga- tions on the “Danmark” Expedition after the death of Mylius Erichsen. ‘‘There is no doubt, that the Eskimos have carried on the musk-ox hunting on a large scale at several places, for example, at Selsé at the head of Dove Bay [i. e. ca. 77° N.B.] — evidence of this is found in the many, large food-depots and the bones in them, which were almost exclusively those of Ovibos moschatus. A number of bones were brought home from the remains of the Eskimo buildings and their determina- Eskimos (Zeitschrift der Ges. fir Erdkunde, Vol. 18, Berlin 1883); C. R. Markham, On the origin and migrations of the Greenlander Esquimaux (Journ. Roy. Geogr. Soc Vol. 35. 1865). 1 Två Somrar i Norra Ishafvet. Stockholm 1900. Vol. II. 397 tion here — by Inspector H. Winge — has proved that among the land animals it was chiefly the musk-ox, which served the Eskimos for food. Reindeer bones occur but in smaller quan- tity. Phoca foetida was found in considerable quantity every- where at the settlements”. Bones of hare, bear, walrus, bearded seal, narwhal, Greenland whale, salmon etc. also occurred. We now have evidence from various sides with regard to the importance the musk-ox has had for the Eskimos, right from the regions between Repulse Bay and Back River! to North-East Greenland. Both the Barren Grounds Eskimos and the Polar Eskimos are very fond of musk-ox flesh and fat. Its fat can also replace the blubber for the lamps, its skin can be used for clothes, and its horns for various implements >”, But we may now ask: if the occurrence of the musk-ox has played so great a part for the migrations of the Eskimos, why is it that we do not find the musk-ox regions inhabited at the present day? — The answer is quite simply: because a lasting settlement of a hunting-people can only occur at the places, where there is always some reserve means of obtaining food should the hunting fail at any time. In the temperate regions there are roots and fruits of plants, bark (e.g. birch- bark) etc. The polar regions do not have such easily obtained plant-materials ; but among the Polar Eskimos, for example, the bird-hunting is such a reserve livelihood in the summer, whilst the seal hunting and in part the walrus hunting are the same in winter. For most of the more southerly arctic Eskimo tribes, fish is the reserve food in summer, and for the sub- arctic tribes this holds good throughout the year. As already mentioned, the coast from Cape York to Etah is, however, an oasis in comparison with other regions in the same latitude. Robeson Channel is poor in seal, walrus and bears; west of Ellesmere Land the northern limit for the seal 1 Е. Boas, The Central Eskimos. Р. 450 et seq. 2 cf. Nathorst, l.c., p.143, Note. 398 and bear passes over the north end of Eureka Sound and goes due westwards from the south end of Heiberg Land!. Thus, for the so-called musk-ox Eskimos the seal and the walrus could not have offered such a certain reserve livelihood or so considerable a store of food as is the case among the Polar Eskimos. The districts about Wellington Channel and the west end of Jones Sound have perhaps been the nearest approach to this. Nor could the birds have been of any import- ance as reserve food during the summer”. The Eskimos must have done the same as the previously mentioned 8 families, who left Peary in 1906 and went to Lake Hazen; they lived on musk-ox and hares throughout the autumn and winter, and in the spring went on to the sea-ice, where they hunted the seal on the way south. The best time of year for the musk-ox hunting is the summer and autumn, at which seasons the animals are fat and owing to their size (up to about 550 kg) are able to yield large quantities of meat and tallow for storage and fuel. These times are the same as the seasons for the true reindeer hunting, and further, the musk-ox lives in quite different localities from those which are suited for the reindeer, as it does not feed on lichens like the latter”; we can understand, therefore, that where the musk-ox hunting is the main source of livelihood, the other forms of summer hunting must be neglected or even quite given up. The forms of hunting which are thus apt to die out of use are for example the kayak hunting and the salmon fishing. We can now understand, why we meet with the winter-houses in the interior of the land at Lake Hazen, whilst tent-rings are found at so many places on the coasts; 1 H.G. Simmons, L.c. р. 179. — Isachsen, l.c. Chart (Pl. 14). 2 Possibly the wild-goose and eider-duck have been of importance locally. — The “Eider-duck nests” found in the west end of Jones Sound and considered by the Sverdrup Expedition as originating from the old Scandinavian Greenlanders, are, I think, old Eskimo egg-depots (cf. p. 300). 3 cf. Nathorst, 1. c., Vol. II, р. 148. — Greely, 1. c., Vol. II, р. 362. 399 these latter have without doubt been set up in the spring-time, especially in May and June, when the Eskimos carried on the ‘“utok” hunting on the sea-ice. For the rest, it appears from the experience of the expe- ditions, that the small Rangifer Pearyi only oceurs in relatively small numbers in Ellesmere Land and North Devon!. On the other hand, apart from the eastern part of North Devon and corresponding stretches in the eastern Ellesmere Land, where the land is high and covered with glaciers, the musk-ox occurs in considerable quantities. The latter, however, which lives in local, small herds, can never become a constant and perman- ent means of livelihood. After being hunted for some time, perhaps as a rule after a single year, the reduced herds of musk-ox can no longer yield the considerable quantities of food for storing, which are required for men and dogs, and the Eskimos must move on. These Eskimo bands cannot have been very numerous. They were most probably groups of ca. 8—10 families, which separated off from the constantly inhabited Eskimo centres on the coast of the mainland and the Barren Grounds. Some have again returned home; others have been enticed so far away, that new generations have perhaps grown up, before the band has gone under during a famine period in one or other out of the way corner”, or perhaps succeeded in reaching a Green- land coast, where a sure, reserve livelihood could be obtained. 1 Greely, 1.с., Vol. II, р. 363; O. Sverdrup, Nyt Land, Vols. I—II; В. Peary, Nearest the Pole, pp. 60, 62, 70 etc. 2 As example cf how quickly a tribe, which has difficulties in finding a reserve mode of obtaining food, may die out, I may mention the inhabi- tants of Southampton Island, a small, almost untouched Eskimo tribe, which lived essentially on reindeer hunting with the bow and arrow and numbered 68 persons in 1900. In 1902 a whaler landed a party of Baffinlanders armed with rifles on the island and these so destroyed the hunting, that the original dwellers all to a man perished of hunger in the course of the winter (А. Р. Low, 1. с., рр. 187—188). 400 The stretch of coast which, from its position and wealth of animal life, as described in preceding pages, is best suited to attract these wanderings bands, is that occupied by the Polar Eskimos. And from these remarks with regard to the wanderings of the musk-ox Eskimos — remarks, which are natur- ally hypothetical, but which can only be contradicted or con- firmed by archæological investigations in the regions mentioned — it will scarcely be surprising, if I express the opinion, that the Polar Eskimos are just the latest arrivals of the musk-ox Eskimos. It is quite possible, of course, that hundreds of years have passed since they came to Greenland; the remains of houses found on Ellesmere Land seem all to be fairly old. It is also probable that the tribe is made up of a fusion of several bands. This view of the origin of the Polar Eskimos I base further on the following points. 1. As I have already pointed before, the Polar Eskimos must at an earlier date have lived under conditions, when the kayak hunting, the reindeer hunting and salmon fishing, or in other words the main, summer modes of livelihood of the ordinary, arctic Eskimo culture, had fallen into disuse. It is difficult to imagine that this happened except under the con- ditions described, when the musk-ox hunting was the main mode of livelihood in the summer. 2. The musk-ox hunting has never been forgotten by the Polar Eskimos and is still to this day a special attraction for them. 3. In their folk-lore and their own experience the regions beyond Smith Sound play a much greater part than, for example, the lands lying to the south of them, and they held the view, at any rate in Kane’s and Hayes’ time, that musk-ox hunting Eskimos lived up here. Thus, a Polar Eskimo, who was con- vinced that Hayes would meet with Eskimos to the north, said: “There are good hunting-grounds to the north, plenty of musk- The shading represents the distribution of the musk-ox. hunting Eskimos. -hunting Eskimos. ..

This explanation of the origin of the Polar Eskimos from the north and west is in itself quite natural. What is remark- able in the matter is, however, that they have come to Greenland more on the basis of a pure land-hunting, such as for the musk-ox, than in their character as dwellers on the coast. And even after they had passed Smith Sound, the Polar Eskimos still retained this distinctive land-life, changing from their earlier summer hunting, the musk-ox hunting, to the still easier bird-catching. They lived for 3 months of the year on the margin of the open sea without standing in any cultural relation whatsoever to it. That they did not build kayaks stands just as much in connection with the fact, that they did not hunt the reindeer as with their relation to the sea; for the Central Eskimos, namely, who live on and near the Barren Grounds, the kayak is chiefly a river-conveyance, which is used in the reindeer hunting of the summer’. The absence of wood would not of itself be a sufficient cause for giving up an established custom of building kayaks, but might well delay the adoption of this apparatus from neighbouring tribes. Had the Polar Eskimos been accustomed to and felt the need of building kayaks, they would certainly have found some way of continuing to do so. The Iglulik Eskimos had certainly just as little wood, and yet Lyon” found kayaks there in 1822, regarding which he writes: ‘The ribs, of which there are sixty or seventy, are made of ground willow, small bones, whalebone, or if it can be procured, of good grained wood”. 1 Hayes, The open Polar Sea, p. 385. — ef.

London 1824, р. 322. 403 The story or tradition which Knud Rasmussen heard!, that some disease had once in the olden days carried away all the old people, who knew how to build kayaks, and that these were buried together with their owners, does not give a rational explanation either of why they should give up the use of the kayaks, since such a cause could have no effect with a tribe accustomed to use the kayak. A probable explanation of the story is, that these kayak builders who died were immigrants — presumably from Baffin Land — who continued their custo- mary summer mode of life, without at that time finding any imitators among the true Polar Eskimos. Taken on the whole, we must guard against concluding that the absence of use means the complete absence of know- ledge. It is not at all strange, therefore, that the Greenlanders more to the south, who certainly must also have come originally along the ‘‘musk-ox way’, early took up the use of the kayak for their hunting by sea. It was only necessary that the whole way from a kayak-building region in America to south of Mel- ville Bay should be traversed by a single band within the period of a single generation, so that some would remain to take the initiative and produce a model for others to follow, when they found it suited the conditions. The same applies with regard to the reindeer hunting, the use of the bow and arrow etc. I shall not enter, however, upon the question of the immigra- tion of the more southerly Greenlanders. From an anthropogeogra- phical standpoint it is obvious, that the main mass must have come down along the west coast. The western immigrants already find the natural basis for a more permanent settlement at Etah, just as the band which goes to the north, first meet with corresponding conditions at Scoresby Sound or perhaps even only at Angmagsalik. Between Scoresby Sound and Angmagsalik lies the coastal stretch charted by Amdrup, which is perhaps the most unap- 1 Nye Mennesker, р. 32. 404 proachable and for the Eskimos most difficult to pass along the whole coast of Greenland. Nevertheless, there is no doubt that there has been some communication along this stretch of coast and certainly in both directions. The old Scoresby Sound Eskimos seem, according to Ryder’, to have been distinctly reindeer hunters, which points to a southern origin. On the other hand, the smallness of the houses, their square-shaped form and various other features point northward to Ellesmere Land”. The rectangular ground-plan however is only a result of using wood or whale-bones for the roof. It is only the places, seemingly, where the roof is also built of stone, that the ground-plan becomes rounded; this holds good, for example, not only for the Polar Eskimos but also at Lake Hazen’°. The fact pointed out by Holm, that the natives of Angmag- salik knew about the musk-ox, suggests that they have been in connection with the north. Among the West Greenlanders there are only uncertain traditions regarding this animal, perhaps indeed it bas been completely forgotten. On the other hand, there is no reason to go so far as Schultz Lorentzen*, who maintains that not only the Angmagsaliker but also the southern West Greenlanders have migrated north and east round Green- land. I am in agreement with О. Solberg” in his criticism of this hypothesis. From the cultural standpoint the Angmagsaliker are decidedly related to the West Greeniand population, but we are obliged to take up the view that they have been mixed with immigrants from the north. In this way we perhaps obtain an explanation of the con- 1 Om den tidligere eskimoiske Bebyggelse af Scoresby Sund. Meddelelser om Grönland 1895. Simmons, 1. с., pp. 190—91.

Recently Thalbitzer has also observed such points of resemblance*. When these authors only mention the Point Barrow Eskimos, the reason is certainly, that we have more definite knowledge of these than of the other tribes along the coast of the mainland to the north. Possibly, these resemblances will also prove to exist with the tribes on the mainland from Boothia Felix to Coronation Gulf, but from these tribes the ‘‘musk-ox way” — also perhaps by slightly different lines from that shown on the accompanying chart — leads northwards round Greenland, where the condi- tions of life will mean a constant advance for a wandering band and not permit of a long sojourn at any definite region. On the other hand, we can hardly think of a direct connection from more westerly regions than Coronation Gulf. ]. с., pp. 152 ef seq. 1. с., р. 343; cf. G.
