FEBRUARY, 1862. No. 1. ARTICLE I. — On, the Primitive Formations in Norway and in Canada^ and their Mineral Wealth, By Thomas Macfarlane, (Presented to the Natural History Society.) Some apology may appear necessary here for the use of a terra, regarded by many geologists as calculated to perpetuate false' ideas as to the character and origin of the series of rocks which it comprehends. The object of the following paper, however, being merely to point out certain analogies, and possibly, differ- ences, between certain groups of rocks in Norway, and their equivalents in Canada, the name given them is of minor import- ance ; and when it is considered how difficult it is to choose among the various terms which have been proposed and used for designating these formations, the one adopted in the above title may appear excusable, and not perhaps be deemed unserviceable on this occasion. The groups of rocks, whose equivalents in Norway I propose in some measure to describe, are here known as the Laurentian system, the Huronian and the Metamorphic Silurian series. The first of these is generally designated the Primitive Gneiss formation, {Urgneiss Formation) in Germany and Scandi- navia, while the two last mentioned groups make up what is termed there the Primitive Slate formation (Urschiefer For- mation). I propose to describe these groups of rocks as they Can. Xat. 1 Vol. VII. 2 Macfarlane on the Primitive Formations occur in Norway, principally in regard to their petrographical and economic characters. I shall follow the order in which they are mentioned above, inserting at the end of each description, a few remarks on their development in Canada. The various facts related in the following descriptions are principally derived from such authorities as Naumaun and Keilhau ; my personal obser- vations of the districts under notice, having only served to im- print on my mind the descriptions of these and other philoso- phers. The particulars narrated as to the various mining estab- lishment^', are to a great extent however, the results of my own experience and observation. As to the various features touched upon with regard to Canada, my principal source of information has of course been the reports of the officers of the Geological Survey. I. The Primitive Gneiss Formation. In Keilhau's "First attempt towards a Geological Map of Norway," as yet the only complete geological map of the coun- try published, there are distinguished three geographical divisions, belono-ino- to the Primitive Gneiss formation, separated from each other by groups of rocks, belonging either to the primitive slate, the eruptive granite and syenite, or to the Silurian series. The first of these is situated high up in Finmark, its most north- ern point being tlie North Cape. The second stretches from Beiern-fiord, north of Trondhiem, along the whole coast of Nor- way, southward to Christiansand, and from thence north-east- ward to Kragero. To this division, the gneiss districts of Kongsberg and Modum also belong. The third division is that lying to the eastward of Christiania-fiord and lake Miosen. These three divisions form only the most westerly parts of the great Primitive Gneiss formation, which extends through Sweden to Finland, and which is the characteristic feature of Scandina- vian geology. The rocks which constitute this formation are the following : — 1. Gneiss in many varieties, the most common being what is called by Keilliau, characteristic gneiss^ and which he thus de- scribes. " Tlie rock consists of white or reddish white feldspar, (orthoclase), grey quartz and black mica; the feldspar and quartz being combined with each other granularly, and the mica ar- ranged in this mass in parallel layers ; so that the structure is more an alternatively granular and slaty one, than a regularly slaty structure, with quite equal distributions of the three con- in Norway and in Canada, 3 stituents. In this way, there is caused a characteristic streaked appearance, sometimes with broad black or dark grey bands, and sometimes with the same streaks, narrower an] farther from each other, according as the mica is more plentifully or more sparingly distributed in the rock. The grains of feldspar, quartz and mica, are mostly rather small in this variety of gneiss, so that it seldom becomes coarsely granular." Gcea Norvegica^ p. 251. Through a gradual disappearance of the feldspar ; the gneiss sometimes changes into mica schist, and through a gradual change in the position of the laminae of mica, from that of parallel layers, to being irregularly distributed, the gneiss often passes into granite. Of the many varieties of gneiss, one deserves special notice ; it has been called Porphyroid gneiss, and differs from the characteristic gneiss in containing lenticular-shaped aggrega- tions of feldspar in a fine schistose matrix. It is this variety which has sometimes been called Eye gneiss. 2. Hornblende gneiss, differing from the characteristic gneiss in having exchanged the scales of mica for crystals of hornblende, arranged parallel with each other according to their longest axis- Sometimes however, the hornblende has only partially supplanted the mica, in which case intermediate varieties are formed between the hornblendic and common gneiss. Through gradual disap- pearance of both quartz and feldspar, the hornblende gneiss often changes into hornblende schist, and sometimes through a change in the structure of the rocks from schistose to granular, syenitic and greenstone rocks are formed. 3. Granite of the usual composition. It often occurs as a very coarse grained aggregation of dark red orthoclase with sparingly distributed quartz and mica. 4. Mica schist, composed of quartz and mica, with a schistose structure, and often containing garnets. It exhibits transitions into hornblendic schist as well as into gneiss, (fee. 5. Hornblendic schist, forming transitions into greenstone, and when the structure continues coarse grained, into diorite and diabase. 6. Chlorite schist, consisting principally of chlorite and a little feldspar ; here and there interwoven with fibres of hornblende. 7. Talc schist, mostly quartzose. 8. Quartz, as granular quartz rock, forming layers and zones ; sometimes slaty, forming quartz slate. 9. Euphotide, consisting of brown diallage and white feldspar. 4: Macfarlane on the Primitive Formations Other rock« allied to this, have been discovered in a good many localities, and described as gabbro. 10. Sfrjyentine, sometimes occurs in such considerable masses a& almost to entitle it to be regarded as a member of the formation. It is generally of a light yellow colour. The well known de- posit of noble serpentine, occurring in the parisii of Snarum, comes under this head. 11. Granular limestone, as marble, in layers and irregular masses. 12. Conglomerates ^Ti^ breccia, mostly the latter. One is de- scribed as " a granite-like combination of gneiss and granite," another " angular pieces of gneiss united by a gneissoid cement ; " a third consists of " a gneissoid or granitic matrix, enclosing small fragments of other gneissoid rocks." Besides the rocks above enumerated, there occur numberless varieti^^s, forming transitions between these types of rock, some of which have been already adverted to. Sometimes, as Naumann remarks, '* within small spaces, one and the same specific com- position shews characters so quickly and so frequently changing, than we soon- get accustomed to seek what is similar, only in the specific identity of the constituents, and not at all in the way or quantity in which they are combined." Beitriige zur Kentniss Norwpgens, I. 188. As the name Primitive Gneiss formation implies, the most widely distributed rock is the gneiss, either in its characteristic form or its varieties. The next most frequently recurring rocks are granite, mica schist and hornblende schist, or rocks related to these types. Some other rocks which I have enumerated, such as chlorite and talc schists, gTanular limestone and quartzitc, occur in comparatively small quantity, while the remainder of those mentioned must be looked upon as uncommon occurrences. As to the mode in which these rocks are associated with each other, the whole of them are arranged in parallel layers or zones, side by side, underlying or overlying each other. Hitherto no regular succession of rocks has been marked ; they appear to be interstratified with each other without rule. The aTanitic masses are partly conformable with the parallel masses of the schistose rocks, and partly occur irregularly. It has been remarked that when the granite becomes more or less gneissoid, its masses are regularly interstratified with the other schistose rocks; but where the granite is totally free from all traces of gneissoid texture, the 171 Norway and in Canada. 5 form in wliich it occurs deviates more or less from that of layers or beds. A remarkable instance of this is described by Keilhau, as occurring near Norefield. There he saw a mass of granite, which on the whole, was gneissoid and bedded, gradually change at a certain place into a perfect granite, and then, in complete uninterrupted continuity, pierce the rock in the form of a dyke. Another instance is mentioned of a granite rock occurring in the schistose rocks, " partly in very regular layers, partly as isolated knolls and lumps, and partly asamultitudeof veins; which in several places run through large portions of the neighbouring mountain as a close net-work." In spite of this however, this granitic rock showed in many places, a gneissoid structure. The relations of the hornblende schists and greenstones resemble those of the granite. The hornblende schist is regularly interstratilied with the gneiss, mica schist and other rocks. Where its texture be- comes less slaty, the layers or zones are not so continuous, but form, in the direction of the strike, elongated nuclei, which, with their hard masses, often stand out from the general surface^ and thus form well distinguished peaks, such as Johnsknuden near Kongsberg, and Fagerlidknatten south-east in Nedenses, In- stances of crystalline amphibolites cutting the strata, occur in the most northern gneiss district, but these appear to have been formed much later than the gneiss. Mention is also made of a diorite, or feldspathic hornblende rock, occurring in veins in a granular mixture of quartz, feldspar and garnet, which latter rock appeared to form a transition into the gneiss. One of the most striking features seen in the structure of this group of rocks, is the foldings and contortions, which the strata exhibit in all the divisions of the group. This is observed as well where no granitic masses are seen, as in the neigh- bourhood of sucL On the high road from Hougsund to Kongs- berg, and shortly before reaching the latter place, the traveller can observe, without dismounting, the most wonderful bends and contortions in the structure of the gneissoid rocks occurring there. Scheerer, in describing these contortions, compares them to the windings figured upon marbled paper. Naumann, in remarking on the same phenomena on the north-west coast, expresses him- self as follows : " It is usually said of gneiss, that it is always clearly and regularly stratified. This assumes thai the parallelism of the masses, of not too great extent, has a relation to one plane ; that the positions of the planes of structure 6 Macfarlane on the Primitive Formations within small distances, are only subjected to sciall, and gpnerally" crradual and continuous alterations; that these do not frequently shew sudden faults, or leaps in the most varied directions, within a few paces. If we however examine much of the gneiss of northern Bergenstift, we find exactly the opposite of this. Let one only observe the profiles which the play of the waves keeps so clearly and distinctly exposed on the rocky banks of Evenig- fiord, Outer Dalsfiord, and especially of Sondelvsfiord. In what absolute indefiniteness, in what indescribable confusion is the structure of the masses exhibited ! And yet there reigns the most unequivocal parallel structure within those thousand-fold mean- dering windings of the single zones, in which no rule, no law is evident, for the wonderful winding appear so lost in each other that neither drawing nor description is able to follow them." In the presence of such contortions, and of local foldings on a larger scale, it is of course difficult to ascertain the general strike of the strata. It seems however, that in all the principal gneiss regions of Norway, the rocks run most generally north and south, or at least N.N.E. and S.S.W., and this, although there are nume- rous exceptions, appears to be the general strike. It seems also that a generalisation is possible as well with regard to the dip, as to the strike of the rooks constituting this gTOup. The strata are almost always vertical or nearly so. This is the distinguishing character of the formation, and, en passant^ let me remark the great difficulty hitherto experienced in all theorizings as to its origin. Horizontal and less inclined strata have indeed been remarked in several places, but they must be regarded as exceptional. The dip is almost always over 45°, generally 60® to 80°, while per- fectly vertical strata arc often observable. These much inclined strata may be traced continuously many miles on the above men- tioned north-easterly strike, and taken together, strike and dip, form a remarkable feature in the architecture of these rocks. As Keilhau remarks, " there lies spread out before us an area of many thousand square miles, which shews only in a few places, any other than steeply inclined strata. In a great many, and indeed we may say in the mo^t and greatest portions of this area, we see these steep strata following some law of regular course. We find them stretching away ten, twenty and often many more geographical miles, according to the same lines, and it ap- pears to us that there where new fields of strike beginj it is still the same parallel masses which we have previously observed, and in Norway and in Canada* 7 wbich have only changed the direction of their strike." Goea Norvegica I, 375, The landscape features in the gneiss region vary much. We find in it sometimes tame hills, flat undulating plateaux, in which only the valleys cut into it, have exposed more rugged forms ; but sometimes we find zigzag ridges, sharp peaks, and other remarkable mountain shapes. In the gneiss districts of the south, long-drawn, broad massive mountain ridges are most common, but on the north-west coast, the gneiss rises in rugged and fantastic forms above the surface of the water, in the numer- ous and intricate fiords of that region. The mineral deposits of these districts are neither few nor un- interesting. Some of these are worked, and produce silver, copper, cobalt, nickel and iron, while others capable of yielding^ some of these metals or other minerals, remain unwrought or undeveloped. Foremost among the modes of occurrence of metals in this region, must be noticed the so-called fahlbands. These are not exclu- sively confined to the south of the Fields which run north-east- ward across Norway at its broadest part, but it is there, and espe- cially in the district of Buskerud, that they have experienced their greatest development. From a point to the west of Kongsberg, and near the junction with the so-called Telleraarken group, after- wards to be described, north-eastward to Tyrifiord, or to where the gneiss formation in Modum is overlaid by Silurian strata, there occurs a series of parallel zones of rock, having the same strike and dip as the rocks enclosing them, but distinguishable from these by the decomposed appearance and reddish-brown color which they present on the surface. This peculiar appear- ance, to which, according to Bobert, they owe their distinguishing name (from/aAZ or /aid, rotten, as the German miners, who first were employed in their exploration, termed them,) is attributable to the metallic sulphurets which they contain, and especially to iron pyrites ; the ferric oxide and the sulphates produced in the oxi- dation of this being the coloring and decomposing agents. The quantity of metallic sulphurets necessary to produce this color- ing and decomposing etiect, is exceedingly small, and indeed it is sometimes scarcely possible to distinguish them, so finely dissem- inated are they through the mass of the rock constituting the fahlband. The sulphurets most generally present are common and magnetic iron pyrites, and copper pyrites; although blende and galena have both been mentioned as impregnating materials. 8 Macfarlane on the Primitive Formations they are comparatively rare. Besides these, cobalt glance, co- baltiferous arsenical, and iron pyrites, nickeliferous magnetic pyrites, and argentiferous iron pyrites characterise peculiar lo- calities. The impregnation seems to be altogether independent of the nature of the rock ; gneiss, mica schist, hornblende schist, « | ters.

Feathers of the head and neck acuminate, inter- of the District of Montreal, 57 nally white, then umber brown, and tipped with whitish brown. Whole dorsal aspect except the wings pure brown ; tail black with minute whitish brown mottlings on the outer vanes of the feath- ers and blotched with pure white on all the inner vanes except the two centre feathers.

Length 38 inches ; alar expanse 72 inches. Another specimen, a younger bird probably, or perhaps of a different sex, presented throughout the same essential characters, but differed slightly in the colour, which was lighter and more rusty. It measured 40 inches with an alar expanse of Y6 inches. The young of this species has often been confounded with that of the F. chrysaetos. The distinguishing characteristic is, that in the latter the tarsi are completely feathered, while in the former they are only feathered on their upper half, the lower half being naked and scaly. The young of the F. albicilla, an European species, resembles our present bird more than any other. Tem- minck has suggested that the tail of the European species is larger than that of ours; Richardson suggests another characteristic, that the upper mandible of the former has two lobes, while that of the i^. leucocephalus has but one. From what I have seen there seems to be a mistake here, for the two specimens alluded to, which have furnished me my description, have very evidently two— a large very obtuse one near the curve, and a 2nd one 58 Dr. A, Hall on the Mammals and Birds not so large, but perfectly distinct behind it, and a little anteriorly to the base of the cere. It is the case also in another specimen which I have since examined. F. haliaetos. Fish hawk or Osprey. Aquila halicetus of Meyer ! Ti/pe of sub gen. Pandion of Cuvier ! Pandion Carolinensis.

He told me so in 1842, when in this city. F. Dawsonis. Dawson's Falcon. (New Species, Hall !) I have only seen two specimens of this beautiful Falcon, the one in the Museum of the Natural History Society, and evidently from its dimensions, as well as fact, a female ; the other a young male belonging to Mr. Hunter, the taxidermist of the Society. The first was bought in the market of Montreal a few years ago, and the second was shot at Lachine this autumn (1861) by a relation of Mr. Hunter. It bears some resemblance to Prof. Cassin's Hiero* oj the District of Montreal, 63 falco sacer, especially his description of the young bird, but dif- * fers from it in having the claws black; and the under part of the claws are not greenish yellow, but of the same hue as the tarsus ; and the general tint of the dark parts of the plumage is not brown, but emphatically slate color. It also somewhat resembles the description given by the same gentleman of the F. atricapillns or plumbarius but differs in having greenish blue tarsi, and a bluish cere, with black irides. I believe this bird to be a new species, and have taken the liberty of calling it after Dr. Dawson the esteemed principal of McGill College. v.s.p. Bill stout, strongly toothed in upper mandible, the tooth corresponding with a notch in the lower one, of a bluish color, ter- minating in a black tip, which is the color of the cere and irides. Tarsi feathered half way to toes, of a dark greenish blue. Toes long, moderately strong, claws black and much curved. Eyelids dirty white this color forming a complete circle round the eyes. Dorsal aspect. The prevailing tint is dark slate color tipped with cinereous on the back of the neck, interscapulars and second- aries, and with rufous on the back, the upper tail coverts tipped with dirty rufous white. Many of the secondaries have a rufous white rounded spot near the end of their outer vanes. Tint of the upper part of the tail of a brownish slate color, with about 1 1 to 14 bars of light rufous terminating in rufous white near the tip, the tail tipped with the same color. The tail consists of about 11 feathers, the extrenjities of which are all rounded. Ventral aspect. Chin and upper part of throat whitish, each feather having a narrow streak along its shaft of slate color. The prevailing tint, like that of the back is slate color, but differing from the back in that each feather has the outer vane white, with an irregular long white spot on the inner vane, leaving the central portion of the prevailing color. Femorals as long as the tarsals, the white on the feathers here assuming almost a banded or barred appearance, which in the female is distinctly so. Under tail coveiis of alternate rufous white and slate colored bars. The under surface of the tail exhibits a rufous tint, while the bars are more distinctly seen. 2nd. Primary longest; 1st shorter than the 3rd, but longer than the 4th ; inner vanes of the primaries barred with white. The female which resembles the male in every respect except the bars on the femorals, had its bill a good deal worn, thus indi- cating it to be an old bird. Length of the male 23^ inches.

Canada, Dr. McCulloch and Dr. Hall. — Specimen in the private collection of the 'late Dr. McCulloch, now possessed by Mrs. McCulloch. Frequently after having examined this bird, the late Dr. McCulloch and myself considered it new, but we had no means of verifying our opinion, until the visit of Prof. Cassin, of Phila- delphia, in 1854. Dr. McCulloch fell a victim to the cholera dur- inir its epidemic of that year, and the following spring it was for warded to Mr. Cassin, in Philadelphia who identified it as a new species. Only one specimen has as yet been obtained in this coun- try, although Mr. Cassin has had the good fortune to secure a second specimen, which now constitutes the representative of this Buteo in the museum of the Academy of Natural Sciences, Philadelphia. of the District of Montreal. 67 In colour it resembles, in some respects, the young of the Circu3 Hudsonius or ferrugineus. The specimen above described was shot in the vicinity, I believe, of Terrebonne, and was brought to the late Dr. McCulloch, by one of the farmers residing in that neighborhood. It is evidently a very rare species, as this is the only specimen of it which has been seen here. The foregoing description I have taken from Prof. Cassin, who has described the bird under its present name, " Buteo insignatus", in his valuable work, " Illustrations of the birds of California, Texas, Oregon, British and Russian America." In memory of the late Dr. McCulloch, and his promotion of the study of the natural sciences in this city, it should receive the name of McCulloch's Buzzard, although Mr. Cassin has attached to it the name of " Canada Buzzard." F, Cyaneus, Hen harrier. F. uliginosus. Wilson and Buonaparte I ! D.c. I have never met with a specimen of this bird, but from its extensive geographical range, it ought to be an occasional visitant with us. The following description is from Nuttal's '* Ornithology of the United States and Canada." "In the old male, the upper parts are of a blueish gray. The quill feathers are white at their origin, and black the rest of their length ; the internal part of the base of the wings, rump, belly, sides, thighs, abdomen and beneath the tail is white without spots; upper part of the tail of a cinereous gray, with the ends of the feathers whitish ; iris and feet yellow; length 20 and 21 inches." We desire only to add to our list of the Falconidae, which we have endeavoured, with every care, to render as perfect and com- plete as possible, that with the varying names given to the species by authors, together with the differences in plumage, (sometimes remarkable) between the male and female bird, and also between that of the young bird and its parents, the greatest of difficulties has originated and has unquestionably caused, in our opinion, some mistakes in the nomenclature. With the exception of the Gull and Tern tribes, to which we might add one or two other genera, we know of none more diflScult of study, or identification than the Hawks. Genus Strix. Gen. char.

This frinire is bounded by a black border. Above the eye the facial circle is incomplete. Ear-tufts of 10 to 12 feathers, black on the outer vanes, and mottled brown on the inner vanes, the smaller posterior ones being wholly brown. Crown,neck, back, rump, scapulars, and wing coverts black, mottled with grey and brown, the light brown bases of the feathers ap- pearing often through the black tips : the grey white on the back having an undulatory appearance. Primaries and secondaries mottled and barred, the inner vanes presenting on their quill halves a fine reddish brown colour, barred with dark brown. These vanes have a peculiar velvety feel, caused by a fine fringe projecting from the superior outer margin of each barb. The reddish brown almost changes to an orange on the secondaries. Tail banded with six blackish brown bars ; the bars most distinct on the inner vanes, which are reddish brown, while the outer vanes, besides the bars, are much mottled with grey and brown.

A line of brown feathers, tipped and barred with white, bounds the facial disk and meets on the throat. Head, neck, back, rump, tail, scapulars, coverts, prim- aries and secondaries, liver brown, barred with white, which has a yellow tinge. These bars are most numerous on the neck, and most distinct on the back ; those of the wings and tail have a brownish tinge, about 5 in number on the latter, and tipped with the same colour, and 5 or 6 on the wings composed of spots which are darker on the outer vanes. Vental aspect. Chin brown ; neck below the brown line con- tinued from the facial disk, white, succeeded by white barred with liver brown. A single bar occurs on each feather, which is also tipped with the same. The bars change to streaks on the breast and belly ; vent and tail coverts and wing coverts yellowish white, the second and last with narrow, brown specks ; tail slate colour, with 5 bars; wings same, barred; femorals and tarsals short, yellow- ish white, with a faint barring ; toes feathered to the last joint.

Length 24 inches ; alar expanse 42 inches. The female and young scarcely differ from the male. In Richardson's description of the comparative lengths of the primaries of this bird, there appears to me to be an error. I have verified mine in several specimens, and find it differing substan- tially from his. And so far from the toes being "only half covered with feathers," in all the specimens that I have seen, they are distinctly covered to the last joint, the feathers thence pro- truding over the talons, and but 4 transverse scales appearing beyond this line, instead of 7 as mentioned by our author. I am inclined to the belief, that the remarks made by him at the end of his description of this bird in his Fauna, must have been de- rived from an imperfect specimen. S. Tengmalmi. Tengmalm's owl.

Facial disk, black in front of and below the orbits ; below and posteriorly white, bordered by blackish grey, bounded by a line of deep velvety brown, mottled with white, and meeting on the anterior part of the throat, where the white predominates, and thence continued upwards to the chin, separated by a msesial line of brown, and downwards for a little distance to the breast ; crown and occiput liver brown, with white spots — these latter most numerous on the crown, and larger and more distinct on the occiput and nape of neck. The dorsal region liver brown, variegated with white spots, which are largest on the scapulars, on some of which a pair may be seen, but most gener- ally, a single one is met with on the outer vane, of a round shape. Primaries marked by 5 rounded white spots on their outer vanes, and 5 correspondent linear bars on the inner ones ; bars broad- est on the secondaries ; tail with 5 imperfect white bars, made up of oval spots on their outer, and of lines on their inner vanes. Ventral aspect. Below the throat the prevailing tint is liver brown, mixed with nearly an equal quantity of white — the former colour predominating on the sides, and the latter on the middle 76 Dr. A. Hall on the Mammals and Birds parts; wing linings and tail coverts dead white, with imperfect brown marks ; wings and tail slate colour, with white spots cor- responding to those on the upper surface; femorals and tarsals yellow white, with dark brown bars, the tarsals continued to toes as far as the insertion of the talons. 3rd primary longest ; 2nd, 4th and 5th subequal ; 1st and Yth equal ; outer barb of the 1st primary revolute ; tail square. Length 12 inches ; alar breadth 20 inches. Eichardson refers the S. Passerina to the S. Tenpmalmi, on no other grounds than a similarity in the plumage of the head. The two birds, however, are totally distinct ; the S. Passerina not only being much smaller than the S. Tengmalmi, but differs also from it in its ventral plumage, which is wholly brown, and moreover, has but three white bars on the tail, whereas the S. Tengmalmi has five. A greater difficulty, however, occurs in the distinctive characters between the S. Balhousii, S. Passerina^ and >S^. Acadica^ which resemble one another in nearly all their essen- tial points. Might not the trifling varieties which are found to exist between them be the result of ao-e ? Nuttal refers the S» Passerina to the S. Acadica, to which I feel also much in- clined to refer the S, Dalhousii. A degree of uncertainty, how- ever, at the best, hangs over these species, which it would require a comparative examination of numerous specimens of different ages and sexes to clear up. The two following species agree with the plates of the respective birds, as figured in Wilson and Buonaparte's splendid work. The descriptions of both of them are taken from prepared specimens, shot in the vicinity of Mon- treal in 1837. S. Acadica. Acadian owl. , S. passerina ? Wilson ! S. Dalhousii? Audubon! S.

In a notice of the Taconic rocks in the last volume of this Journal, (p. 379,) it was explained that Emmons asserts that in going eastward from the line of fault which brings up the Taconic group to overlie the Trenton and Loraine formations, we meet suc- cessively with lower rocks, all dipping eastward, until in the Green Mountain gneiss we have a rock which is older than the Taconic group ; so that the newest rocks appear to be at the base, and the oldest at the summit of the series. It was however main- tained, in opposition to this view, that the apparent order of super- position from the great fault, going eastward to the Green Moun- tains is in the main, the true one, and that the black slates of Em- mons, which he regards as the newest rock of his series, are really the oldest; while the Green Mountain gneiss is a rock higher in the series than any of those to the west of it. These propositions we still maintain, but in explaining what we conceive to be Mr. Emmons' error, we have said that in order to explain this supposed inversion in the succession of the rocks, he Dr, Hioit on the Tacoiiic System of Emmons. 79 imagines a great overturn of the whole series in question. In this we have been misled by the language of Mr. Emmons, which has caused him to be misinterpreted by others as well. In speaking of the succession of rocks, he uses the term "inverted strata," and Mr. Barrande has spoken of the " overturn (renversement) of the whole system." Mr. Marcou, apparentlv as the interpreter of Emmons, speaks of the strata in question as having been " overturned {renversees) on each side of the crys- talline and eruptive rocks which occupy the centre of the chain, presenting thus a fan-shaped structure, and all the accidents which accompany a complete overturn of a whole system of strata," so that in going eastward towards the centre of the chain, we find that the most recent strata appear to be placed beneath the most ancient, "in consequence of an overturn {renversement).'''' Comjytes Rendus de VAcad. xliii. 804. Now in justice to Mr. Emmons it should be said, that despite his use of the expression " inverted strata," he has never main- tained any inversion or overturn, as a careful examination of his descriptions will show. (Taconic St/stem. p. 17). He supposes that during the accumulation of the Taconic rocks, the gneiss which formed the eastern limit of the basin was progressive^' elevated, so as to successively bring the older members above the ocean from which the sediments were being deposited ; and that the upper parts of the formation, such as the black slates, were thus confined to a narrow basin, and never extended far eastward ; at the same time he conceives that denudation may have removed large portions of the upper beds. At a subsequent period a series of parallel faults, with upthrows to the eastward, is supposed to have broken the strata, given them their eastward dip, and caused the older beds to overlap the inner ; thus giving rise not to an in- version of the strata, but to an apparent inverted succession. Now we find in Canada abundant evidence that the slates which Em- mons regards as the newest, are really near the base of the series, and cannot consequently admit his hypothesis to explain an order of things which we conceive to have no existence. The careful study of the region in question shows, that although such a great upthrow and overlap does bring the Quebec group to the surface from beneath the higher rocks, to the east of this fault undulations, overturns, and downthrows to the eastward, diversify, with eastern upthrows, the structure of this complicated region. The gneiss of the Green Mountains, like that of the Scottish High- lands and like the granite of the summits of the Alps, is the newest 80 Miscellaneous, rock of the chain, the structure of all these mountain regions being synclinal, as we have endeavoured to show in the case of the Alps, {SilUman's Journal {2) xxix. 118,) and as Sir Roderick Murchison has beautifully represented in his late section across the Scottish Highlands. (See his new Geol. Map of Scotland). MISCELLANEOUS. CHROMIC IRON ORE AND ASBESTUS. We copy from a late number of the Chemical News, the fol- lowing notice of the chromic iron and asbestus from the vicinity of Baltimore, lately imported into England. It is known to many of our readers that the Geological Survey has already shewn the existence in several parts of the Eastern Townships, and in Gaspe, of large deposits of this valuable ore, equal in richness to the samples from the United States : — " The amount of sesqui-oxide of chromium in the present ore, as determined by Dr. Genth, is stated to be equivalent to 63 per cent, of chromic acid — a mode of ex- pressing the value of the ore by the quantity of chromic acid produced on fusion with an alkali, and not that of the green sesqui- oxide actually contained therein. Ore of this superior description may be obtained in casks ready for shipment, at the rate of about one dollar for each one per cent, of chromic acid per ton, and in quantities of about 200 tons annually. It is, however, considered more judicious to work this ore in admixture with other qualities which are produced in greater abundance, — 1500 tons annually, — the average composition of such samples furnishing usually about 50 per cent of chromic acid. The ore last described was accompanied by specimens of asbestus, and of paper con- taining about one-third proportion of the same. This mineral may be procured at the rate of 1^ cents per pound, — a low price considering the high quality of the article offered. The specimen sent is beautifully white, and the fibres are long and delicate. It has been tried in America for paper-making and for the manufacture of steam-packing, in both of which applications it is said to be very serviceable. Its property of resisting heat, and its bad conducting power, would render this material particu- larly valuable in connection with steam machinery. The sheet of paper sent is a portion of an experimental manufacture ; it burns with flame, leaving a white incombustible residue, which, with careful management, retains the form of the original sheet ; the weight of ash amounting precisely to 30 per cent."

No. 2. ARTICLE Yl.— Notes on the Flora of the White Mountains, in its Geographical and Geological relations. By J. W. Dawsok, LL.D., F.G.S. (Read before the Montreal History Society.) The group of the White Mountains is the culminating point of the northern division of the great Appalachian range, extending from Tennessee to Gaspe in a south-west and north-east direc- tion, and constituting the breast-bone of the North American con- tinent. This great ridge or succession of ridges has its highest peaks near its southern extremity, in the Black Mountains ; but these are little higher than their northern rivals, which at least hold the undisputed distinction of being the highest hills in north- eastern America. As Guyot* has well remarked, the White Mountains do not occur in the general line of the chain, but rather on its eastern side. The central point of the range, represented by the Green Mountains and their continuation, describes a great curve from Gaspe to the valley of the Hudson, and opposite the middle of the concave side of this curved line toweis the almost isolated group of the White Hills. On the other side is the narrow val- ley of Lake Champlain, and beyond this the great isolated mass of the Adirondack Mountains, nearly approaching in the altitude of their highest peaks, and greatly exceeding in their geological * Silliman's Journal. Can. Nat. 6 Vol. VII 82 Dr. Dawson on the Flora age, the opposite White Mountain group. The Appalachian range is thus in this part of its course, supported on either side by outliers higher than itself. My present purpose is not to give a general geographical or geological sketch of the White Mountains, but to direct attention to the vegetation which clothes their summits, and its relation to the history of the mountains themselves. For this purpose I may first shortly describe the appearances presented in ascending the highest of them, Mount Washington, and then turn to the special points to which these notes relate. In approaching Mount Washington by the Grand Trunk Rail- way, the traveller has ascended from the valley of the St. Law- rence to a height of 802 feet at the Alpine House at Gorham. Thence in a distance of about 8 miles along the bank of the Pea- body River, to the Glen House, he ascends to the elevation of 1632 feet above the sea ; and it is here or immediately opposite the Glen House, that the actual ascent begins. The distance from the Peabody River, opposite the hotel, to the summit is nine miles, and in this distance we ascend 4656 feet, the total height being 6288 feet above the sea.* Formerly only a bridle path led up this ascent ; but last year a regularly| graded and ad- mirably finished carriage road was opened, by which visitors can drive comfortably to the top and back without any of the fatigue formerly experienced. This enterprise, almost |Worthy of com- parison with the great roads over the passes of fthe^Alps, was un- dertaken several years ago by a joint-stock company, and has at length been finished, at a cost, T believe, of $40,000, the interest on which it is hoped will be paid by the tolls levied on travellers, whose annual numbers are estimated at about 5000 for this road* This royal road to the summit is however by|far too democratic for the taste of some visitors, who mourn the olden days^of po- nies, guides, and adventures ; and though it gives an excellent view of the geological structure of the mountain, it does^not afford a good opportunity for the study of the alpine flora, which is one of the chief attractions of Mount Washington. For this reason^ though I availed myself of the new road for gaining a general idea of the features of the group, I determined to ascend by Tuckerman's ravine, a great chasm in the mountain side, named in honour of the indefatigable botanist of the North American * According to Guyot, but some recent surveys make it^a^little higher j of the White Mountains, • 83 lichens.* I was aided in this by the kindness of a gentleman of Boston, well acquainted with these hills, and passionately fond of their scenery. Our party, in addition to this gentleman and my- self, consisted of two ladies, two children, and two experienced guides, whose services were of the utmost importance, not only in indicating the path, but in removing windfalls and other obstruc- tions, and in assisting members of the party over difficult and dangerous places. We followed the carriage road for two miles, and then struck off to the left by a bridle path that seemed not to to have been used for several years — the gentlemen and guides on foot, the ladies and children mounted on the sure-footed ponies used in these ascents. Our path wound around a spur of the mountain, over rocky and uneven ground, much of the rock being mica slate, with beautiful cruciform crystals of andalusite, which seemed larger and finer here than in any other part of the mountain which I visited. At first the vegetation was not materially different from that of the lower grounds, but as we gradually ascended we entered the " evergreen zone," and passed through dense thickets of small spruces and firs, the ground beneath which was carpeted with moss, and studded with an immense profusion of the delicate little mountain wood-sorrel (^Oxalis acetosellci), a characteristic plant of wooded hills on both sides of the Atlantic, and which I had not before seen in such profusion since I had roamed on the hills of Lochaber Lake in Nova Scotia. Other herbaceous plants were rare, except ferns and club-mosses ; but we picked up an aster (^,. acuminatus)^ a golden rod, (^Solidago thyrsoidea), and the very pretty tway blade [Listera cor data). In ascending the mountain directly, the spruces of this zone gradually degenerate, until they present the appearance of little gnarled bushes, flat on top and closely matted together, so that except where paths have been cut, it is almost impossible to pene- trate among them. Finally they lie flat on the ground, and be- come so small that, as Lyell remarks, the rein-deer moss may be seen to overtop the spruces. This dwarfing of the spruces and firs is the eftect of adverse circumstances, and of their struggle to extend their range toward the summit. Year by year they • Dr. Bigelow and Prof. Tuckerman have been the chief botanical ex- plorers of the White Mountains ; though Pursh was the first to determine some of the more interesting plants, and Peck, Booth, Oakes and othera, deserve honourable mention. §4 • Dr, Daimon on the Flora stretch fortli their roots and branches, bending themselves to the ground, clinging to the bare rocks, and availing themselves of every chasm and fissure that may cover their advance : but the conditions of the case are against them. If their front advances in summer it is driven back in winter, and if in a succession of mild seasons they are able to gain a little ground, less favourable seasons recur, and wither or destroy the holders of their advanced positions. For thousands of years the spruces and firs have striven in this hopeless escalade, but about 4000 feet above the sea seems to be the limit of their advauce, and unless the climate shall change, or these trees acquire a new plasticity of constitution, the genus Abies can never displace the hardier alpine inhabitants above, and plant its standard on the summit of Mount Wash- ington. I was struck by the similarity of this dwarfing of the upper edges of the spruce woods, to that which I have often observed on the exposed northern coasts of Cape Breton and Prince Edward Island, where the woods often gradually diminish in height to- ward the beach or the edge of a clifi", till the external row of plants clings closely to the soil, or rises above it only a few inches. The causes are the same, but the appearance is more marked on the mountain than on the coast. On the path which we followed, before we reached the upper limit of trees, we arrived at the base of a stupendous cliff", forming the termination of a promontory or spur of the mountain, sepa- rating Tuckerman's ravine from another deep depression known as the Great Gulf. From the top of this precipice poured a little cascade that lost itself in spray long before it touched the tops of the trees below. The view at this place was the most impressive that it was my fortune to see in these hills. 0[)posite the mouth of the Great Gulf, and I suppose at a height of about 3000 feet, is a little pond known as Hermit Lake. It is nearly circular, and appears to be retained by a ridge of stones and gravel, perhaps an old moraine or sea beach. On its margin piped a solitary sand-piper, a few dragon flies flitted over its sur- face, and tadpoles in the bottom indicated that some species of frog dwells in its waters. High over head and skirting the edges f the precipices, soared an eagle, intent no doubt on the hares that frequent the thickets of the ravines. Before we reached Hermit Lake we had been obliged to leave ^our horses, and now we turned aside to the left and entered of the While Moimtains. 85 Tuckerman's ravine, where there is no path, but merely the bed of a brook, whose cold clear water tumbles in a succession of cascades over huge polished masses of white gneiss, while on both sides of it the bottom of the ravine is occupied by dense and al- most impenetrable thickets of the mountain alder (Alnus viridis.) Tuckerman's ravine has been formed originally either by a subsidence of a portion of the mountain side or by the action of the sea. It is, like most of the ravines and '* gulfs " of these hills, a deep cut or depression bounded by precipitous sides, and terminating at the top in a similarly precipitous manner. It must at one period have been in part filled with boulder clay, steep banks of which still remain in places on its sides ; and ex- tensive landslips have occurred, by which portions of the liniiting cliflfs have been thrown toward the centre of the valley, in large piles of angular blocks of gneiss and mica slate, in the spaces between which grow gnarled birches and spruces that must be used as ladders and bridges whereby to scramble from block to block, by every one who would cross or ascend one of these rivers of stones. At the head of the ravine we paused to rest, to admire the wild prospect presented by the ravine and its precipitous sides, and to collect the numerous plants that flower on the surrounding slopes and precipices. Here on the 19th of August were several large patches of snow, one of them about an hundred yards in length. From the precipice at the head of the ravine, poured hundreds of little rills, and several of them collecting into a brook, had excavated in the largest mass of snow a long tunnel or cavern with an arched and groined roof. Under the front of this we took our mid-day meal, with the hot August sun pouring it^ rays in front of us, and icy water gurgling among the stones at our feet. Around the margin of the snow the vegetation pre- sented precisely the same appearances which are seen in the low country in March and April, when the snow banks have just disappeared — the old grass bleached and whitened, and many perennial plants sending up blanched shoots which had not yet experienced the influence of the sunlight. The vegetation at the head of this ravine and on the precipices that overhang it, presents a remarkable mixture of lowland and mountain species. The head of the ravine is not so high as the limit of trees already stated, but its steep sides rise abruptly to a plateau of 5000 feet in height intervening between Mount Wash- 86 Dr, Dawson on the Flora ington and Mount Munro, and on which are the dark ponds or tarns known as the Lakes of the Clouds, forming the sources of the Amonoosook river, which flows in the opposite direction. From this plateau many alpine plants stretch downward into the ravine, while lowland plants availing themselves of the shelter and moisture of this cul-de-sac, climb boldly upward almost to the higher plateau. Other species again occur here which are found neither on the exposed alpine summits and ridges nor in the low country. Conspicuous among the hardy climbers are two coarse and poisonous weeds of the river valleys, that look like intruders into the company of the more dwarfish alpine plants ; — the cow-parsnip {Heracleum lanatum) and the white hellebore ( Veratrum viride). Both of these plants were seen struggling up through the ground at the margin of the snow, and climbing up moist hollows almost to the top of the preci- pices. Some specimens of the latter were crowded with the in- fant caterpilars of a mountain butterfly or moth. Less conspicuous, and better suited to the surrounding vegetation, were the bluets ( Oldenlandia coerulea)^ now in blossom here as they had been months before in the low country, the dwarf cornel ( Cornus Can- adensis)^ and the twin-flower {Linncea borealis), the latter reaching quite to the plateau of the Lake of the Clouds, and en- tering into undisputed companionship with the truly alpine plants, though it is also found at Gorham four thousand feet lower. Of the plants which seemed to be confined or nearly so to the upper part of the ravine, one of the most interesting was the northern painted cup, {Castelleia septentrionalis) a plant which abounds on the coast of Labrador and extends thence through all Arctic North America to the Rocky Mountains, and is perhaps identical with the C Sibirica of Northern Asia and the C. pallida of Northern Europe. Large beds of it were covered with their pale yellow blossoms on the precipitous banks overhanging the head of the ravine. With the painted cup and here alone, was another beautiful species of a very difierent order, the northern green orchis, (^Platanthera hyperhorea) a plant which occurs, though rarely, in Canada, but is more abundant to the northward. Here also occurred. Peck's geum, {G. radiatum, var.), Arnica mollis^ and several other interesting plants. Of the Alpine plants which descend into the ravine, the most interesting was the Greenland sandwort, (Arenaria [Alsine) Groenlandica) which was blooming abundantly, with its clusters of the White Mountains, 87 of delicate white flowers, on the very summit of the mountain, and could be found here and there by the side of the brook in the bof torn of the ravine. Clambering by a steep and dangerous path up the right side of the ravine, we reach almost at once the limit beyond which the ordinary flora of New England can extend no longer, and are in the presence of a new group of plants comparable with those of Labrador and Greenland. Here, on the plateau of the Lake of the Clouds, the traveller who has ascended the giddy preci- pices overhanging Tuckerman's ravine, is glad to pause that he may contemplate the features of the new region which he has reached. "We have left the snow behind us, except a small patch which lingers on the shady side of Mount Munro ; for it is only in the ravines into which it has drifted an hundred feet deep or more, that it can withstand the summer heat until August. We stand on a dreary waste of hard angular blocks of mica slate and gneiss, that lie in rude ridges as if they had been roughly raked-up by Titans who might have been trying to pile Monro upon Washington; but which seem to be merely the remains of the original outcropping edges of the rocks broken up by the frost, but not disturbed or rounded by water. Behind us is the deep trench-like ravine out of which we have climbed : on the left hand a long row of secondary summits stretching out from Mount Washington to the south-westward, and designated by the names of a series of American statesmen. In front this range descends abruptly in great wooded spurs or buttresses to the valley of the Amonoosook which shines in silvery spots through the trees far below. On our right hand towers the peak of Mount Washington, still more than a thousand feet above us, and covered with angular blocks, as if it were a pile of fragments rather than a solid rock. These stones all around and up to the summit of the mountain, are tinted pale green by the map lichen (Lecidea Geogra- phica) which tinges in the same way the alpine summits of European mountains. Between the blocks and on their sheltered sides nestle the alpine flowering plants, of which 20 species or more may be collected on this shoulder of the mountain, and some of which ex- tend themselves to the very summit, where Alsine Groenlandica and the little tufts of deep green leaves of Diapensia Lapponica with a few Carices seem to luxuriate. Animal life accompanies these plants to the summit, near which I saw a family of the snow bird {Plectrophanes nivalis) evidently summer resident* 88 Dr» Dawson on the Flora here, and a number of insects, conspicuous among which was a brown butterfly of the genus Hipparchia, Shortly before sun- down, when the thermometer at the summit house was fast set- tling toward the freezing point, a number of swallows were hawk- ing for flies at a great height above the highest peak. To what species they belonged I could not ascertain. Possibly the cliflF swallows find breeding places in the sides of the ravines, and rise over the hill top to bask in the sunbeams, after the mountain has thrown its shadows over their homes. To return to the alpine flora which is peculiar to the peaks of these mountains — are the species comprising it autochthones originating on these hill tops and confined to them, or are they plants occurring elsewhere, and if so where ; and how and when did they migrate to their present abodes ? These are questions which must occur to every one interested in geology, botany, or physical geography. They have been answered in various ways; but without entering into controversy, I shall merely state a few facts, bearing on and illustrating that view which I myself prefer. Not one of the alpine plants of Mount Washington is peculiar to the place. Nearly all of them are distinct from the plants of the neighboring lowlands, but they occur on other hills of New England and New York, and on the distant coasts of Labrador and Greenland, and some of them are distributed over the Arctic regions of Europe, Asia and America. In short they are strag- glers from that Arctic flora which encompasses the north polar region, and extends in promontories and islands, along the high cold mountain summits far to the southward. Some of the humble flowerless plants of these hills are of nearly world wide distribution. I have already noticed the pale green map lichen which tints the rocks of the Pyrenees, the Alps, and the Scottish Highlands ; and the curious ring lichen {Parmelia centrifuga) paints its conspicuous rings and arcs of circles alike on Mount Washington and the Scottish hills. A little club moss {Lycopodium selago) is not only widely distributed over the northern hemisphere, but Hooker has recognised it in the Antarctic regions. Not long ago we unrolled in Montreal an Egyptian mummy preserved in the oldest style of embalming, and found that, to preserve the odour of the spices, quantities of a lichen (Evernia furfuracea) had been wrapped around the body and had no doubt been imported into Egypt from Lebanon or the hills of Macedonia for such uses. Yet the specimens of the White Mountains, 89 from this old mummy were at once recognised by Professor Tuckerman as identical with this species, as it occurs on the White Hills and on Katahdin in Maine. These facts are how- ever easily explicable in comparison with those that relate to the flowering plants. The spores of lichens and mosses float lighter than the lightest down in the air, and may be wafted over land and sea, and drop- ped everywhere to grow where conditions may be favourable. Had the Egyptian embalmer used some of the first created spe- cimens of Evernia furfuraeea, it might easily within the three thousand years or so since his work was done, have floated round the world and established itself on the White Hills. But, as we shall see, neither the time nor means would suffice for the flower- ing plants. The only available present agency for the trans- mission of these would be in the crops or plumage of the migratory birds ; and when we consider how few of these on their migra- tions from the north could ever alight on these hills, and the rarity of their carrying seeds in a state fit to vegetate, and further that few of these plants produce fruits edible by birds, or seeds likely to attach themselves to their feathers, the chances become infinitely small of their transmission in this way. The most pro- fitable course of investigation in this and most other cases of ap- parently unaccountable geographical distribution, is to inquire as to the past geological conditions of the region, and how these may have affected the migrations of plants. The earlier geological history of these mountains far ante- dates our existing vegetation. It belongs in the first instance to the Lower Devonian period, in which the materials of these moun- tains were accumulating, as beds of clay and gravel, in the sea bottom. These were buried under great depths of newer de- posits, and were baked and metamorphosed into their present crystalline condition. Again heaved above the sea level, they were hewn by the action of the waves to some degree into their present forms, and constituted part of the nucleus of the Ameri- can continent in the tertiary period. They were again with all the surrounding land depressed under the sea in the newer Plio- cene period, and in the Post-pliocene or modern, slowly upheaved again to their present height. These last changes are those that concern their present flora, and their relations to it are well stated by Sir C. Lyell in the following passages from his interesting ac- count of his ascent of Mount Washington in 1846. 90 Dr. Dawson on the Flora " If we attempt to speculate on tlie manner in which the pecu- liar species of plants now established on the ] highest summits of the White Mountains, were enabled to reach those isolated spots, while none of them are met with in the lower lands around, or for a great distance to the north, we shall find ourselves trying to solve a philosophical problem which requires the aid not of botany alone but of geology, or a knowledge of the geographical changes which immediately preceded the present state of the earth's surface. We have to explain how an Arctic flora con- sisting of plants specifically identical with those which in- habit lands bordering the sea in the extreme north of America, Europe and Asia, could get to the top of Mount Washington. Now geology teaches us that the species living at present on the earth are older than many parts of our existing continents ; that is to say they were created before a large portion of the existing mountains, valleys, plains, lakes, rivers, and seas were formed. That such must be the case in regard to Sicily, I announced my conviction in 1833, after first returning from that country, and a similar conclusion is no less obvious to any naturalist who has studied the structure of North America, and observed the wide area occupied by the modern or glacial deposits, in which marine shells of living but northern species are entombed. It is clear that a great portion of Canada, and the country surrounding the great lakes, was submerged beneath the ocean when recent species of mollusca flourished, of which the fossil remains occur about 500 feet above the level of the sea at Montreal. Lake Champlain was a gulf or strait of the sea at that period, large areas in Maine were under water, and the White Mountains must then have con- stituted an island or group of islands. Yet as this period is so modern in the earth's history as to belong to the epoch of the existing marine fauna, it is fair to infer that the Arctic flora now contemporary with this was then also established on the globe. " A careful study of the present distribution of animals and plants over the globe, has led nearly all the best naturalists to the opinion that each species had its origin in a single birth-place, and spread gradually from its original centre to all accessible spots fit for its habitation, by means of the powers of migration given to it from the first. If we adopt this view, or the doctrine of specific centres, there is no difficulty in comprehending how the Cryptogamous plants of Siberia, Lapland, Greenland, and Labrador, scaled the heights of Mount Washington, because the of the White Mountaim. 91 sporules of the fungi, lichens, and mosses, may be wafted through the air for indefinite distances like smoke ; and in fact heavier particles are actually known to have been carried for thousands of miles by the wind. But the cause of the occurrence of Arctic plants of the Phoenogamous class on the top of the New Hamp- shire Mountains, specifically identical with those of remote polar regions, is by no means so obvious. They could not in the pre- sent condition of the earth affect a passage over the intervening lowlands, because the extreme heat of summer and cold of win- ter would be fatal to them. We must suppose, therefore, that originally they extended their range in the same way as the plants now inhabiting arctic and antarctic lands disseminate them- selves. The innumerable islands in the polar seas are tenanted by the same species of plants, some of which are conveyed as seeds by animals over the ice when the sea is frozen in winter, or by birds ; while a still larger number are transported by floating icebergs, on which soil containing the seeds of plants may be carried in a single year for hundreds of miles. A great body of geological evidence has now been brought together to show that this machinery for scattering plants as well as for carrying erratic blocks southward, and polishing and grooving the floor of the ancient ocean, extended in the western hemisphere to lower lati- tudes than that of the White Mountains. When these last still constituted islands in a sea chilled by the melting of floating ice, we may assume that they were covered entirely by a flora like that now confined to the uppermost or treeless region of the mountains. As the continent grew by the slow upheaval of the land, and the islands gained in height, and the climate around these hills grew milder, the Arctic plants would retreat to higher and higher zones, and finally occupy an elevated area which probably had been at first or in the glacial period, always covered with perpetual snow. Meanwhile the newly formed plains around the base of the mountain, to which northern species of plants could not spread, would be occupied by others migrating from the south, and perhaps by many trees, shrubs, and plants, then first created, and remaining to this day peculiar to North America." The time to which the above views of Sir C. Lyell would refer the migration of the White Mountain flora, is historically very re- mote. The changes of level which have submerged the American continent and re-elevated its land, have occupied long periods. Whether with Lyell we measure these periods by the recession 92 Dr. Dawson on the Flora of the Falls of Niagara, or by the growth of the alluvial plain of the Mississippi ; or with Agassiz, by the extension of the Peninsula of Florida, or endeavour to estimate the time required for the abrasion and deposition of the great mass of clay that fills the valley of the St. Lawrence, we cannot suppose that less than two or three hundred centuries have elapsed since the alpine plants of the White Mountains were cut off from all connection with their Arctic relatives. Their reign upon the mountain tops not only antedates all human dynasties, but reaches far beyond the creation of man himself and many of his contemporaries. Positive evidence of the existence of some of these plants dur- ing a large portion of this lapse of time, has actually been pre- served in the Post-phocene deposits of Canada. At Green's Creek on the Ottawa, in nodules in the clay containing marine shells, and coeval with the Leda clay of Montreal, there are numerous remains of plants that have been embedded in this clay at a time when the Ottawa valley was a bay or estuary, and when the Adirondack Mountains of New York and the moun- tains of New England were two rocky islands separated from each other, and from the mainland on the north, by wide arms of the sea. The plants found in these nodules all appear to be of mo- dern species. It is of course not easy to recognise the specific characters in these fragments, but I think I have good evidence of Potentilla Norvegica^ P. tridentata, and possibly P. Canadensis; Populus balsamifera, Arctostaphylos uva-ursi, Trifolium repenSy Drosera rotundifolia, Potamogeton natans, and P. perfoliatum.* There are also seeds apparently of ranunculaceous plants ; grasses and carices, and mosses. Several of these plants are found on the White Mountains, and they are all northern and arctic species. I have no doubt that further examination of these deposits will lead to the discovery of additional examples. This fact, proving as it does the existence of these species at the period in which the theory of Lyell and Forbes requires them to have migrated,, is in itself strong corroborative evidence. We can say that some of these species were waiting on the shores of the north, ready to be drifted to the insular spots to the south-west, and that their seeds were actually being washed out to sea by the streams which emptied themselves into the then estuary of the Ottawa. * These determinations were made from specimens in the collection of the Geological Survey, and from others kindly collected for me by (^ the White Mountains. 93 Another aspect of the inquiry which has perhaps not been re- garded with sufficieot attention, is that which relates to the re- duction of temperature, which might be consequent on the great •depression of the land which we know to have existed at the close of the tertiary period, a fact on which I have insisted in former papers on the Post-pliocene deposits of Canada.* A very clever writer on the subject of geographical distribution,f has pictured the case of a subsiding continent with the fauna and flora of its lowlands becoming gradually concentrated on the spots which had previously been alpine summits, but now reduced to low and temperate islands. But he has left out of view the fact, that if land still existed in mass in the arctic regions, and if the subsid- ence was that of land in temperate regions, then on the principles long ago so well stated by Sir C. Lyell, these islands might have a mean temperature far below that of the former plains, and might in consequence be suitable only to such an alpine flora as that which they had previously borne. Now this is precisely what occurred in the I^ost-pliocene pe- riod. The arctic land remained in great mass, detaching into the sea annual crops of icebergs, which have strewed all the north- ern hemisphere with boulders : the temperate regions were sub- merged except a few insular spots. These are the very con- ditions required for a low mean temperature both in the sea and on the land, and these geographical conditions correspond pre- cisely with the facts as indicated by the fossil animals and plants of the period. Further, it would be easy to show that the alpine plants of Mount Washington would thrive under such conditions as those supposed, at the sea level ; a low and equable temperature with a moist atmosphere being that which they most desire, and their greatest enemy being the dry parching heat of the plains of the temperate regions. Those of them, such as Potentilla tridentataj Linncea borealis^ and Alsine Groenlandica, wliich occur within the limits ot the United States, are found under shaded woods, in damp ravines, or on the moist sea coast; and as we follow the coasts northward, we find these plants on thesc^ and on neighbor- ing islands, in lower latitudes than those in which they occur in- land. When the summer mists roll around the summit of Mount Washington, it is in every respect the precise counterpart of an * Canadian Naturalist, Vol. IV. f Wollaston. 94. Dr, Dawsoii on the Flora islet anywhere on the coast of America from Cape Breton to the arctic seas, and when winter wraps everything in a mantle of snow, all these lands are in like manner under the same conditions. So in the Post-pliocene period, though the islets of the White Mountains may have experienced a less degree of winter cold, they must have had very nearly the same summer temperature as now; and as this is the season of growth for our alpine and arc- tic plants, it is its character that determines the suitableness of the locality to them. Those stupendous vicissitudes of land and water which have changed the aspect of continents, and swept into destruction races of gigantic quadrupeds, have dealt gently with these alpine plants, which long ages ago looked out upon a waste of ice-laden waters that had engulfed the Pliocene land with all its inhabitants, as securely as they now look down upon the pleasant valleys of New England. It is curious too that the humbler tenants of the sea have shared a similar exemption. In the clay banks of the Saco, on the shores of Lake Champlain, and mixed with the remains of these very plants in the valley of the Ottawa, are shells that now live in the Gulf of St. Lawrence and on the coast of Maine, intermixed with other species that are now found only in a few bays of the Arctic seas. Just as in the Post-pliocene clays of the Ottawa, the remains of arctic plants are found in the same nodule with those of Leda truncata, so now similar associations may be taking place on the coasts at the mouth of the Great Fish River. Truly, in nature as in grace, God hath chosen the weak things of the world to confound those that are mighty, and has left in the earth's geological history, monuments of his respect and regard for the humblest of his works. We look in vain among the alpine plants so long isolated in these mountains, for any evidence of decided change in specific characters. The alpine plants for ages separated from their arc- tic brethren, are true to their kinds, and shew little tendency to vary, and none to adapt themselves to new forms in the sunny plains below. This is especially noteworthy in Mount Washing- ton and the neighboring peaks, because the soil of these is the same with that of the valleys below. Several of the plants pecu- liar to these hills, as the black crow-berry (Fmpetrum nigrum), for instance, even when other conditions are favourable, shun rich calcareous soils, and aft'ect these of granitic origin. In many cases the difference in soil is a sufficient reason for the non-occurrence of the White Mountains, 95 of such plants except on certain hills. At Murray Bay, and on the shores of Lake Superior, the plant above named occurs only on the Laurentian gneiss. In Nova Scotia, its relative, Corema Conradi, is confined to the granite barrens of the south coast. Many such plants skirt the whole Laurentian range from Labra- dor to Lake Superior, but refuse to extend themselves over the calcareous plains of Canada. But in the White Hills the soil of the river alluvium is the same micaceous sand that fills the cre- vices of the rocks in the mountains, and hence there is no ob- struction, in so far as soil is concerned, to the diff'usion of plants upward and downward in the hills. In like manner there is every possible condition as to moisture and dryness, sunshine and shade, in both localities. These circumstances are of all others the most favourable to such variation as these plants are capable of under- going. The case is the same with that which Hugh Miller so strongly puts in relation to the species of algae that occur at dif- ferent distances below high water mark on the coast of Scotland, each species there attaining a certain limit, and then instead of changing to suit the new conditions, giving place to another. So it is on Mount Washington ; and this whether we regard the lowland plants that climb to a certain height and there stop ; the plants that are common to the base and summit, or the plants that are confined to the latter. I have already referred to the evident struggle of the spruces and firs, and the plants associated with them, to ascend the moun- tain ; and the same remark applies to all the plants that one after another cease to appear at various heights from the lower valleys. One by one they become stunted and depauperated, and then cease, without any semblance of an attempt to vary into new and hardier forms. And this must have been proceeding, be it ob- served, from all those thousands or myriads of years that have elapsed since the elevation of the mountains out of the glacial seas. It is to be observed also that the new plants that occur in ascend- ing, often belong to different genera and families from those left behind, not to closely allied species ; and in the few cases in which this last kind of change occurs, there is no graduation into interme- diate forms. For instance Solidago thyrsoidea and >S^. vi>ya-aurea occur around the base of the mountain, and for some distance up its sides. At the height of four to five thousand feet, the latter only remains, and this in a dwarfish condition. This corresponds to its distribution elsewhere, for according to Richardson it occurs in 96 Dr, Dawson on tlie Flora lat. 55° to 65*^ in Arctic America, and according to Hooker it is found in the Rocky Mountains, while it also occurs in the hills of •Scotland, and very abundantly in some parts of Norway. In the White Mountains aS'. thyrsoidea prevails toward the base, S. virga- aurea toward the summit ; and at the top of Tucker man's ravine I found the former of these golden-rods in blossom, within a few hundred feet of the latter, each preserving its distinctive peculi- arities. Much has lately been said of the appearance of specific diversity that results from the breaking up of the continuity of the geographical areas of plants by geological changes ; but here we probably have the converse of this. The mountain species is no doubt a part of the older arctic flora, the other belongs to the more modern flora of the plains, and they have met on the sides of the White Hills. Some hardy species climb from the plains to heights of 5000 feet or more, with scarcely even the usual change of being de- pauperated, and then suddenly disappear. This is very note- worthy in the case of two woodland plants, the dwarf cornel or pigeon-berry {Cornus Canadensis), and the twin-flower (^Linnosa borealis). The former of these is a plant most widely distributed over northern America, and probably belongs to that newer flora which overspread the continent after its re-elevation. In August this plant in the woods around the base of Mount Washington is loaded with its red berries. At an elevation of four to five thousand feet it may be found in bloom ; above this a few plants appear destitute of flowers, dwarfish in aspect, and nipped by cold, and then the species disappears. No doubt the birds that feed on its little drupes have carried it up the mountain, and have sown it a little farther up than the limit of its probable reproductiveness. The beautiful little Linncea is a still more widely distributed plant; for it occurs on the hills of northern Europe, and is found across the whole breadth of the American continent from Nova Scotia to the Columbia River. It is almost beyond question a member of the old arctic flora which colonised the islands of the Post-pliocene sea, and has descended from them on all sides as the land became elevated. This plant also climbs Mount Wash- ington to a height of 5000 feet, and presents precisely the same characters on the top as at the bottom, only losing a little in the length of its stem. Specimens bearing blossoms and quite in the same stage of growth, may be collected at the same time on the highest shoulders of Mount Washington, and on the flats at Gor- of the WJiite Mountains. 97 ham. The Linncea in this is true to its designation. For as if it belonged to it to support the reputation of the great systematist after whom it is named, it preserves its specific characters with scarcely a tittle of change throughout all its great range. One cannot see this hardy little survivor of the glacial period, so un- changing yet so gentle, so modest yet so adventurous, so wide in its migrations yet so choice in the selection of the mossy nooks which it adorns with its pendant bells, and renders fragrant with its delicious perfume, without praying that we might in these days of petty distinctions and narrow views, be favoured with more such minds as that of the great Swede, to combine the little de- tails of the knowledge of natural history into grand views of the unity of nature. Another plant which, being less dependent on shade and shel- ter than the Linncea^ mounts still higher, is the cowberry or fox- berry ( Vaccinium vitis-Idma). This also is both European and American, and is probably a survivor of the Post-pliocene period. It still occurs in at least one locality in the low country of Massa- chusetts, and on the coast of Maine. It is found along the gran- itic coast of Nova Scotia, and extends thence northward to the arctic circle, being found at Great Bear Lake and at Unalaska. This too is a most unchanging species, and the same statement may be made respecting Ruhus Chamcemorus, the cloud-berry, Empetrum nigrum^ the black crowberry. Ledum lati/olium, the Labrador tree, Potentilla tridentata^ the three toothed cinque-foil, which grows on ihe coast of Nova Scotia, and is found in the nodules of the Ottawa clay, the same in every detail as on Mount Washington, Vaccinium uUginosum, the bog bill berry, and V. coespitosum, the dwarf billberry. Several of these too it will be observed, are berry-bearing plants, whose seeds must be deposited in all kinds of localities by birds. Yet they never occur in the warm plains, nor do they show much tendency to vary in the dis- tant and somewhat dissimilar places in which they occur. In the case of most of these species, the most careful, comparison of spe- cimens from Mount Washinijton with those from Labrador, shows no tittle of difference. When we consider the vast length of time during which such species have existed, and the multiplied vicis- situdes through which they have passed, one is tempted to believe that it is the tendency of the " struggle for existence" to confirm and render permanent the characters of species rather than to modify them. Can. Nat. T Vol. YII. 98 Dr* Dawson on the Flora Of the more specially arctic plants which have held their ground unchanged on Mount Washington, the following are some of the principal. Diapensia Lapponica in beautiful deep green tufts ascends quite to the summit. It occurs also in the Adir- ondack Mountains, and on Mount Katahdin in Maine. It is found in Labrador, and according to Hooker, extends north to Whale Island in the Arctic seas ; but it is not found west of the Great Fish River. It occurs also on the mountains of Lapland, and is described as the hardiest plant of that bleak region. Arenaria {Alsine) Groenlandica, the Greenland sandwort, adorns with its clusters of white flowers every sandy crevice in the rocks of the very summit of Mount Washington, and is trodden under foot like grass by the hundreds of careless sight-seers that haunt the peak in summer ; though I should add that not a few of them carry off little tufts as a memento of the mountains, along with the fragments of mica which appear to form the ordinary keepsakes of unscientific visitors. It is a most frail and delicate plant, seemingly altogether unsuited to the dangerous pre-emi- nence which it seeks, yet it loves the bare unsheltered mountain peaks, and when it occurs in the more sheltered ravines, has only its stems a little longer and more slender. It occurs on the Adirondack Mountains and on Katahdin, where — if I may judge from specimens kindly sent to me by Mr. Goodale — it attains to smaller dimensions than on Mount Washington, on the Katskills, and at one place on the sea coast of Maine. I have not seen it in Nova Scotia, but it ranges north to Greenland. Another of the truly arctic plants is the alpine azalea (Loi- seleuria procumhens), a densely tufted mountain shrub, with hard glossy leaves, that look as if constructed to brave extremest hard- ships. It is found on the mountains of Norway, at the height of 3550 feet on the Scottish Hills according to Watson, and ac- cording to Fuchs at the height of 7000 feet in the milder climate of the Venetian Alps. In America it is found in Newfoundland, in Labrador, and in the barren grounds from lat. 65^ to the ex- treme arctic islands. Gray does not mention its occurrence else- where in the United States than the summits of the White Moun- tains. A member of the same family of the heaths, the yew- leaved phyllodoce {P. taxifoUa)^ presents a still more singular dis- tribution. It is found on all the higher mountains of New England and New York, and occurs also on the mountains of Scotland and Scandinavia, but its only known station in northern ^ of the White Mouviains, 9D America is, according to Hooker, in Labrador. As many as nine or ten of the alpine plants of the White Mountains belong to the order Ericaceoe. Another example from this order is Rhododen- dron Lapponicum, a northern European species, as its name in- dicates, and scattered over all the high mountains of New Engr- land and New York, occurring also in Labrador, on the arctic sea coasts, and the northern part of the Rocky Mountains. It would be tedious to refer in detail to more of these plants, but I must notice two herbaceous species belonging to diflferent families, but resembling each other in size and ha\)it — the alpine epilobiura [E. alpinum or alsine/oUum), and the alpine speed- well ( Veronica alpina). Both are in the United States confined to the highest mountain tops. Both occur as alpine northern plants in Europe, being found on the Alps, on the Scottish High- lands, and in Scandinavia. Both are found in Labrador, and on the Rocky Mountains, and the Veronica extends as far as Green- land. The alpine epilobium is one of the few White Mountain plants that have attained the bad eminence of being regarded as doubtful species. Gray notes as the typical form, that with ob- tuse and nearly entire leaves, and as a variety, that with acute and slightly toothed leaves, which some other botanists seem to regard as distinct specifically. Thus we find that this little plant has been induced to assume a suspicious degree of variability ; yet it is strange that both species or varieties are found growing together, as if the little peculiarities in the form of the leaves were matters of indifference, and not induced by any dire necessities in the struggle for life. Facts of this kind are curious, and not easily explained under the supposition either of specific unity or diversity. For why should this plant vary without necessity, and why should two species so much alike be created for the same locality. Perhaps these two species or varieties, wandering from far distant points of origin, have met here fortuitously, while the lines of migration have been cut off by geological changes, and yet the points of difference are too constant to be removed even after the reason for them has disappeared. If this could be proved, it would afford a strong reason for believing the existence of a real specific diversity in these plants. I have said nothing of the grasses and sedges of these moun- tains ; but one of them deserves a special notice. It is the alpine herd's grass (^Phleum alpinum), a humble relation of our common herd's grass. This plant not only occurs on the White Moun- 100 Dr, Dawson on the Flora tains, in arctic America, and on the hills of Scotland and Scan- dinavia, but has been fotind on the Mexican Cordillera, and at the Straits of Magellan. The seeds of this grass may perhaps be specially suited for transportation by water as well as by land. It is observed in Nova Scotia that when the wide flats of mud deposited by the tides of the Bay of Fundy, are dyked in from the sea, they soon become covered with grasses and carices, the seeds of which are supposed to be washed down by streams and mingled with the marine silt ; and fragments of grasses abound in the post- tertiary clays of the Ottawa. It seems almost ridiculous thus to connect the persistence of the form of a little plant with the subsidence and elevation of whole continents, and the lapse of enormous periods of time. Yet the power which preserves unchanged from generation to generation the humblest animal or plant, is the same with that which causes the permanence of the great laws of physical nature, and the continued revolutions of the earth and all its companion spheres. A little leaf entombed ages on ages ago in the Post-pliocene clays of Canada, preserves in all its minutest features the precise type of that of the same species as it now lives, after all the ■prodigious geological changes that have intervened. An arctic and alpine plant that has survived all these changes, maintains in its now isolated and far removed stations, all its specific characters unchanged. The flora of a mountain top is precisely what it must have been when it was an island in the glacial seas. These facts relate not to hard crystalline rocks that remain unaltered from age to age, but to little delicate organisms that have many thousands of times died and been renewed in the lapse of time. They show us that what we call a species represents a decision of the unchanging creative will, and that the group of qualities which constitutes our idea of the species, goes on from generation to generation animating new organisms constructed out of different particles of matter. The individual dies but the species lives, and will live until the Power that has decreed its creation shall have decreed its extinction ; or until in the slow process of physical change depending on another section of His laws, it shall have been excluded from the possibility of existence anywhere on the surface of the earth. While the huge ribs of mother earth that project into moun- tain summits, and the grand and majestic movement of the crea- tive processes by which they have been formed, speak to us of of the White Mountains. 101 the majesty of Him to whom the sea belongs, and whose hand formed the dry land, the continuance of these little plants preaches the same lessons of humble faith in the divine promises and laws, which our Lord drew from the lihes of the field. It is suggestive in connection with the antiquity and migra- tions of these plants, to consider the differences in this respect of some closely allied species of the same genera. Of the blueberries that grow on the White Mountains, one species, Vacdnium ulig- inosurifij is found at Behring's Straits and in northern Europe. F. ccespitosum has a wide northern range in America, but is not European. V. Pennsylvanicam and V. Canadense from their geographical distribution do not seem to belong to the arctic flora at all, but to be of more southern origin. The two bear- berries {Arctostaioliylos uva-ursi and alpina), occur together on the White Hills, and on the Scottish and Scandinavian moun- tains, but the former is a plant of much wider and more southern distribution in America than the latter. Two of the dwarf wil- lows of the White Mountains i^Salix repens and S. herhacea), are European as well as American, but aS^. uva-ursi seems to be con- fined to America. Ruhus trijiorus, the dwarf raspberry, and E. Chamoemorus, the cloud-berry, climb about equally high on Mount Washington, but the former is exclusively American and ranges pretty far southward, while the latter extends no farther south than the northern coast of Maine, and is distributed all around the arctic regions of the Old and New Worlds. It is to be ob- served, however, that the former can thrive on rich and calca- reous soils, while the latter loves those that are barren and grani- tic ; but it is nevetheless probable that R. trifloms belongs to a later and more local flora. Similar reasons would induce the be- lief that the American dwarf cornel or pigeon-berry, (^Cornus Canadensis)^ whose distribution is solely American and not pro- perly arctic, is of later origin than the C. Suecica, which occurs in northern America locally, and is extensively distributed in northern Europe. I can but glance at such points as these ; but they raise great questions which are to be worked out, not merely by the patient collection of facts, but by a style of scientific thought very much above those which on the one hand escape such problems by the supposition of multiplied centres of creation, or on the other, render their solution worthless by confounding races due to ex- ternal disturbing causes with species originally distinct. Diffi- 102 Archhold on the failure of the Apple Tree culties of various kinds are easily evaded by either of these ex- treme vifews; but with the fact before him of specific diversity and its manifestly long continuance on the one hand, and the remark- able migrations of some species on the other, the true naturalist must be content to work out the problems presented to him with the data afforded by the actual observation of nature, following carefully the threads of guidance thus indicated, not rudely breaking them by too hasty generalisations. ARTICLE VIT. — On the failure of the Apple Tree in the neigh- bourhood of Montreal. — A communication to the Committee of the Natural History Society of Montreal. By Joun Archbold. The failure of the apple trees in the neighbourhood of Montreal, and I believe in all the Island, is a sad calamity as regards do- mestic luxury, as well as in a commercial point of view. I have seen Montreal, in its palmy days of apple-growing, export its thousands of barrels of Pomraes Crises, Bourassas, and Fameuses. These were the principal sorts sent to Europe, the refuse of which, as well as the great quantities of wild apples, that is apples from seedlings, always found a ready market at Quebec and the ports below it, at remunerative prices. With these facts clearly before us, it is not to be wondered at that strict enquiry should be made by all who feel the least interest in the culture of the apple, as to the cause of its decay. I have been a resident in Montreal since 1832, and for the last twenty -five years have lived on the south-eastern slope of the Mountain, on the Cote St. Antoine road, and have acted in the capacity of gardener at Mount Pleasant, the then residence of the late Joseph Savage, Esq.; also at Rosemount, the residence of the Hon. John Young, and subsequently at Forden, the residence of Capt. R. T. Raynes, and of the late Charles Bowman, Esq. ; one of the most zealous friends and supporters of Horticulture, in his day, that Montreal could boast of. All these places were noted for the production of fine varieties of the apple, the pear, and the plum. The latter place, Forden, in particular, used to yield about fifteen years ago, from 1000 to 1500 lbs. of fruit, but the last three years have made sad havoc with the trees, and unless some reaction in the growth takes place, there will not be one of the old trees living three years hence. I noticed the decline of some sorts of the apple in the neighbourhood of Montreal. 103 twenty years ago. I had a talk with the late Henry Corse, Esq., about that time, on the failure of the Early Harvest apple, and he was under the impression that it was then extinct about Montreal, but I convinced him that it was not, for in each of the above mentioned places, I had seen trees of the Early Harvest which gave from three to four barrels of good apples, but these few trees are, I have every reason to believe, now gone. There were also the Ribston Pippin, (much on the decline these last ten years,) the Keswick Codlin, Hawthornden, Grant's Major, John Richardson ; but these and some others, I always looked upon as being tender, from the softness of their wood, which is not nearly 8o hard as that of the Bourassa, Pomme Grise, and Faraeuse, and therefore do not wonder at their destruction. These latter sorts have, however, for the last ten years, been declining in the vigour of their growth, and the size of their fruit. I was for some time under the impression from what I could learn from some garden- ers, and other cultivators of fruit, that the above named three sorts of apples, would not bear fruit in any other locality than in the Island of Montreal, but that impression was completely re- moved, by visiting the Provincial Exhibition held at Brantford, C. W., some years ago. I saw there as fine specimens of the Bourassa, as Montreal could produce in its best days. At Ham- ilton I also visited some of the gardens, and there to my surprise, I found the Pomme Grise, Fameuse, and Ribston Pippin, growing side by side, and loaded with fine fruit, with not the slightest appearance of decay. These remarks, however, are by the way ; the point of discussion, at present, is the cause of the decay in the apple trees in the vicinity of Montreal. There will no doubt be a great many opinions put forth on the subject, and some light will I hope be thus thrown on both the cause and the cure. Were the decay confined to one place, one kind of soil, or one mode of pruning or culture, there would be less difficulty in discovering both the cause and cure ; but when we find the decay, in one fell swoop, taking off the whole of the young orchards that have been planted within these fifteen or twenty years past, and that even the old savage^ as the Canadians call it, that has stood the severity of the winters for the last fifty years, is suffering the same fate, the difficulty of giving an opinion is ail the greater. When also it is observed that apple trees both in the most shel- tered nooks and on the bleakest exposures, on the best alluvial soil, and on the gravelly and limestone rock, all alike share the 104 ArchhoJd on the failure of the Apple Tree same fate, the necessity of careful consideration is much increased. I noticed in several of the apple trees, after the severity of the winter three years ago, that many of the large limbs became disordered by their cellular tissues not admitting that uniform and free flow of sap to the outer extremities of the branches, which was necessary for healthy growth. The consequence was, that there remained in the trunk an overflow of sap, and some very severe freezing nights coming at the time, the sap froze, and caused the outer bark to burst ; the trunk soon after presenting a black and decaying appearance. This is one of the causes to which I attribute the decay. I have also observed in gardens and orchards, at a season when the trees are in full vigour of flower and foliage, that they have been completely denuded of their leaves by the ravages of the caterpillar. Thus being left bare to the influence of a June sun, their health and vigour were seriously impaired. I have observed that trees which suff"ered so, for two years in succession, hardly ever recovered from the eftects of it ; this is one other cause to which I attribute the decay of the apple. To avoid injury to the trees, care should be taken as to the time ot pruning. When this is done in the beginning of March, or, as is sometimes the case, before that time, and wounds are left bare, without any cover or protection, the influence of a hot sun by day, and hard frost by night, is such, that these wounds emit a portion of the sap, and cause the parts atlected to become black, a sure forerunner of decay. In my humble opinion, that work should be deferred till later in the season. My reason for forming this opinion is, that I have observed in my practice of budding, which com- mences about the middle of July for stone fruits, and continues all through August for the pear and the apple ; that having to cut and prune the stocks to a considerable extent, I always found the wounds, at that season, to heal up very quickly, and leave no trace of black, such as might be seen in early spring pruning. Another cause of decay, seems to me to be some kind of atmospheric agency, for I have frequently noticed a portion of the branches of apple trees becoming black in parts where there were no wounds. Sometimes at the junction of the lateral branches with the main branch, and sometimes near the outer extremity of the branch. Some persons attribute the appearance to lightning, but that appears to me rather doubtful, for although thunder and lightning are common in the summer months, in Canada, I never in the neighbourhood of Montreal, 105 noticed any parts of apple trees to be blackened to the extent tbey now are, until these last four years past. There might, indeed, occasionally have been symptoms of decay in some trees, and in certain localities, but the cause in such cases was easily ac- counted for. This commonly occurred when trees were planted in hard blue sub-soil, saturated with water at all seasons of the year, without the least attention being paid to drainage. On consulting any of the British authors who have written on the culture of the apple, they will all be found to agree that the soil should undergo a thorough preparation, previous to planting, and that it should be trenched at least to the depth of two feet. If such preparation is an essential in such a mild climate as Great Britain, it is much more so in Canada, where we have frequently such a long continuance of drought in the summer, and severe frost in the winter. I have often been struck with the short life of the apple trees about Montreal. There was an impression made on my mind, in early life, that the apple was a long lived tree. I have known apple trees in the west of Ireland, in the neighborhood of the town of Sligo, to attain the age of 150 years, and then to be bearing good crops of apples. I also find that A. J. Downing, one of the most reliable and best American au- thors, in writing on the age of the apple, says he saw in* Rhode Island, two trees 130 years old. He however reckons our fine garden sorts to live only from 50 to 80 years. Now, I ques- tion if we could find about Montreal, any of our fine garden sorts half that age, that is 40 years old. He also strongly recommends trenching the soil, and says it adds greatly to the long life of the trees. I must confess that I have not seen that proper attention paid to fruit trees in the neighborhood of Montreal which they re- quire. I have seen, in many cases, trees planted on the green sward, without any other preparation than simply making a hole and putting in the tree ; leaving it afterwards to take care of it- self. In such cases the result may be easily conjectured. In taking up numbers of both pear and apple trees, the heads of which were dead, I have found that their roots were generally perfectly sound, not showing the least symptom of decay below the surface. The cause of decay does not therefore lie with the root. The question often occurs to me, shall we ever see Montreal producing the fine fruits that it did twenty-five years ago ? The markets were then filled to overflowing with the finest varieties of the plum and the pear, and a pretty good quantity of the peach 106 Dr. Dawson on an Erect Sigillaria and apricot, of open wall culture. Now there is no such thing to be found as a good Bon-chretien pear, or an Autumn Bergamot, or a Burmese Spruce, or yet a luscious Bolman's Washington plum, or a Greengage, or even a coarse Magnum Bonum ; and but sel- dom will you find a good basket of the common wild red plum of the country. I have also noticed a de(4ine in the vigour and growth of several other plants, these last few years past, in com- parison with what might have been seen twenty years ago. Then I saw the gardens about Montreal produce enormous crops of melons, with very little care or attention ; now it is uncertain if you get a good crop with all the care you can give them. I have also Seen good crops of grapes raised in the gardens, and have myself raised at Mount Pleasant, good crops of the Sweet Water and Black Cluster in good condition, in the open ground. Then there was no such thing as the mildew, or the nip, as it is now ; nor was that troublesome pest, the curculio, known about Montreal. Yet with all these facts before us, it will not do to be idle lookers on ; better to be up and doing. I would suggest that any man possessed of land, whether little or much, should plant trees ac- cording to his means, and let what is planted, be planted in the best possible way, and under the best conditions of soil and cul- ture. He may then hope for good results in time to come. These few remarks, hastily penned, are respectfully submitted to the Montreal Natural History Society. Forden, 6th January, 1862. ARTICLE VHL — On an Erect Sigillaria and a CarpoUte from Nova Scotia, By J. W. Dawson, LL.D., F.G.S. (jPVotA the Journal o/ the Geological Society of London.') 'I'he erect trees so frequent in the Joggins coast-section, though often distinctly ribbed, rarely show the minute markings of the leaf-scars in a sufficiently perfect state to enable them to be compared with those of the flattened trunks seen in the shales and ironstones. This, no doubt, arises in part from the circum- stance that the bases of the trunks of Sigillarice did not always retain their characteristic markings, and in part from the unfavour- able influence of an erect position in coarse and often laminated sediment. The specimen, to which this note relates, and which I obtained in 1859 from a sandstone in Group XIV. of my sec- tion of the South Joggins*, affords an exception to the generally ♦ Quart. Journ. Geol. Soc. vol. x. r. 6. and a CarpolUefrom Nova Scotia, 107 imperfect condition of these trunks sujQSciently remarkable to merit a short notice. The specimen measures 3 feet in height, and is 10:J- inches in diameter at the base, 9 inches in the middle, and 7^ inches at the top, where it was abruptly broken oflf. (Fig. 1.) At the base it shows the usual tendency to divide into four main roots ; but these hare been nipped off or flattened by pressure, not having been filled with sediment. The trunk retains its form on one side, but on the other the bark has been rent from top to bottom, and in part folded inward. This seems to have been caused by the pressure Fig. 1. Fig. 2. of the surrounding sediment, and has probably somewhat dimin- ished the diameter of the stem. The interior of the trunk is filled with grey sandstone, similar to that of the enclosing bed. The outer bark, less than a line in thickness, is in the state of bituminous coal ; and an internal cast with a thin coaly envelope represents the pith. This internal cast extends through the great- er part of the length, but has fallen to one side. It is only half an inch in diameter. The coaly matter remaining on its surface shows, when prepared with nitric acid, cellular structure ; and traces of transverse Sternbergian markings remain in parts of it, so that it must not be regarded as the woody aziSy which has di^ appeared, but merely as the pith-cylinder. The leaf-scars and other surface markings are preserved throogh- outthe specimen, but only in a few places in suflScient perfection to show the more minute features of the former. At the upper 108 Dr, Dawson on an Erect Sigillaria part the ribs are very prominent, and there are twenty-six in the whole circumference, the breadth of each rib being about nine- tenths of an inch. On the outer or cortical surface each rib is flattened, or even concave, along the middle, and strongly round- ed at the sides, descending into deep intercostal furrows ; the flat mesial portion being smooth, the lateral portions marked with sharp vertical ridges, and in places with very delicate longitudinal and transverse striae. The leaf-scars extend across the smooth middle portion of the rib, and are distant from each other one inch vertically. In form they resemble those of Sigillaria trans- versalis, S. Defrancii," and S. Brochantii, Brongt., being trans- versely lanceolate, emarginate above, with acute lateral edges. Those best diplayed show two vascular punctures, with a third mark or prominence between and rather below them. On the so-called ligneous surface, or that of the inner bark, the ribs are slightly furrowed or striated lengthwise ; and the leaf-scars are re- presented by two deep punctures of the vascular scars. (Fig. 2.) In tracing the ribs downward, some of them wedge out and dis- appear : so that at the middle of the length of the trunk there may be about 22 ; each with a breadth increased to one inch and four-tenths, and flatter than those at the top, with the intercostal furrow shallower. The leaf-scars are now widened transversely, aud have lost their minute markings on the cortical surface ; while on the ligneous surface the vascular punctures are twice as far apart as at the top. About the middle the vertical distance of the scars diminishes somewhat suddenly to seven-tenths of an inch. In the lower third of the stem the ribs are quite obliterated, and the whole surface is wrinkled with coarse waving striae or small furrows, due apparently to the expansion of the outer bark. The leaf-scars still remain in regular vertical rows ; but these are reduced to about twelve, and apparently at the base to as few as nine. The vertical distance of the scars is still about 0*7 inch ; but the transverse distance between the centres of the rows is in- creased to 2-8 inches or more. In form the leaf-scars are now transverse furrows, an inch or more in length, and the vascular punctures are half an inch or more apart in each scar. A single row of these wider scars is shown in (Fig. 3.) Of the roots I could obtain no specimens ; but the markings on the bark at the base of the trunk are precisely similar to those on many Stigmarian roots found attached to less perfectly preserved and a Carpolite from Nova Scotia, 109 stems, and a few stigmaroid areoles are perceptible on the lower sur- face of the stump. The woody axis has entirely disappeard, nor does any mineral charcoal appear in the base of the cast. It has either been en- Fig. 3. tirely removed by decay, or has been washed out by the waves before the hollow bark was filled up. As this trunk appears to belong to a species not previously de- scribed, and we have a better knowledge of its parts and mode of growth than of those of most of the named species, I may pro- pose for it a specific appellation, and would call it Sigillaria Browniiy in commemoration of the many interesting discoveries in relation to these plants made by my friend Richard Brown, Esq., of Sydney, Cape Breton. The following are the most important points relating to Sigillanoe in general, illustrated by the specimen above-de- scribed :— 1. The evidence of the exogenous growth of Sigillaria. The growth of the trunk took place, as I have elsewhere main- tained,* by the introduction of new woody wedges in the axis and' by additions to the surface of the axis and to the inner bark, after the manner of exogenous stems. When the present trunk had nine rows of scars it was only three inches in diameter, perhaps much less, and as it grew in height the base expanded in such a man- ner as to increase the distances between the scars and the distances between the vascular punctures in the scars, while new rows of leaves were added above until the number amounted to about 2G. The same appearances in a species quite distinct from the present • Quart. Journ. Geol. Soc. vol. x. p. 32. 110 Dr. Dawson on an Erect Sigillaria are illustrated in my paper on the South Joggins section. Speci- mens which I have observed, however, as well as facts stated by Mr. Brown and by Brongniart, induce me to believe that in some species this mode of growth was so far modified that new ribs were introduced to the very base of the trunk. The expansion of the trunk was accompanied by the flattening out of the ribs, and also by the giving way of the thin outer bark, the inner or middle bark evidently remaining in a growing state lo the base of the stem. 2. The decadence of the leaves from the lower part of the trunk in the living state, is proved by the condition of the scars. We may also note the shorter vertical distance of the scars on the lower part of the trunk, showing that, when young, the leaves were much more crowded than subsequently : and the absence of bands of deformed and crowded scars sometimes seen on Sigillarice^j probably connected with periods of fructifi- cation, and possibly occurring on the upper part of the trunk only. 3. The difficulty of comparing the characters of erect with those of prostrate Sigillarioe; the former usually showing only the base of the stem, the latter often only the upper part, and these differing so materially that they may be mistaken for distinct species. 4. The mode of growth illustrated by the specimen may apply only to a portion of the plants usually included in the genus. The spe- cies of Sigillaria found at the Joggins may amount to about twenty ; and with reference merely to the habit of growth, with- out regard to the resemblances or differences in the leaf-scars, these may be arranged in three groups. The first will include the present species with S. reniformis^ S. alternans, S. organumj and another [S. ovalis, mihi) with oval scars like those of S' ca- tenulata but an inch apart vertically. These have broad and well- marked ribs, attain to a large size, and often occur erect. Other species with narrow and less distinct ribs and more or less crowd- ed scars, as S. elegans, JS, Knorrii, S. scutellata, S. Saullii, (fee, do not appear to have attained to so great diameter, and are more rarely seen erect. In some of these species the markings and leaf-scars seem to be more perfectly preserved to the very base of the trunk than in the species before mentioned. A third group consists of species like S. De/ranciij S. Menardiij &c., which are destitute of ribs and have the scars arranged spirally. Some of these were of considerable diameter, others quite small ; but they are rare, and I have not recognized them in the erect position, * Ibid. vol. xv. p. 640. and a Caryolke from Nova Scotia, 111 5. In connection with the absence of the usual remains of wood as mineral charcoal from this trunk, it may be stated that the bast-like tissue of the inner bark of SigUlarice is abundant in some of the coal of the Joggins ; whilst the discigerous tissue* is prevalent in the great Pictou coal-seam. In the former case the decomposition of the vegetable matter was probably sub- aerial, or like that of a forest-soil ; whilst the conditions of the latter were those of peaty bogs. Carpolite from the Coal-Formation of Cape Breton. All the best authorities on coal-plants are disposed to refer the seeds or fruits known by the generic names Trigonocarpum and Rhabdocarpus to phaenogams, and probably to gymnosperms. In this case they may have belonged to Coniferce or Sigillarioe, or to both. That they belonged in great part to the latter is, I think, rendered probable by their occurrence very abundantly in the mid- dle part of the coal-measures where SigUlarice abound, by their various forms corresponding rather to the many species of /S^i^iZfoWoE than to thefew of Conifers, and by their abundant occurrence in the interior of hollow stumps of Sigillarios and in the surrounding beds. Still these fruits or seeds may have belonged to very dif ferent plants ; and as an example of the type of structure most frequently associated with SigUlarice^ I have prepared a short notice of a species of which very well-preserved specimens exist in my collection, and to which I have assigned the name of Trigonocarpum Hookeri. Numerous specimens of this species occur in a thin calcareous layer in the coal-measures near Port Hood, Cape Breton. They are not compressed, and are fossilized by calc-spar and iron- pyrites. Their form is ovate, — the length being 0-3 inch, and the breadth 0*2 inch. The external surface is rough and destitute of distinct markings. Internally they present the following struc- tures : — 1. An outer coat (^to), which is thick, carbonaceous, and apparently of a dense cellular structure. This corresponds to the outer supposed " fleshy coat" of Lindley and Ilooker ; but in this species I think it must have been firm and hard, like the outer coat of the seeds of pines, which it much resembles in ap- pearance and structure. 2. An inner coat (tegmen or emhryo-sac) * Ibid. vol. xii. p. 631. 112 Dr, Dawson on an Erect Sigillaria which is thin and marked on its outer surface with interrupted ridges, almost precisely in the manner of the corresponding coat in the seed of Pinus pinea.

When the seed is sliced longitu- dinally, the nucleus is seen to present an outer thick layer of calc- spar, stained by vegetable matter, and an inner mass which is colourless. In the smaller end, toward the micropyle, the remains of the embryo and its suspensor are seen replaced by iron-pyrites, in the manner represented in fig. 3. In some specimens the outer coat appears as if divided into two layers, and the nucleus has shrunk inwards from the inner coat, presenting two additional surfaces, which may represent original lines of structure, but are perhaps, results of decay. A very similar species, which occurs in vast abundance in the interior of an erect Sigillaria at the Joggins, has the outer coating v^ry dense and coaly, and with a transverse fibrous structure. In some specimens it shows a projecting ridge on each side, and longitudinal striae, which might entitle it to be placed in the genus Rhabdocarpus ; but no coal-fossils are more deceptive than these carpolites, which, when flattened or deprived of their outer coats, present appearances very dissimilar from those of the perfect condition. I am by no means certain that this note adds much to the know- ledge already possessed of the structure of Trigonocarpum ; but it aff'ords an additional example, and this of a species similar to those most frequently associated with remains of Sigillarice, ARTICLE IX. — On the Primitive Formations in Norway and in Canada, and their Mineral Wealth. By Thomas Macfarlane. {Continued from page 20.) II. The Primitive Slate Formation. A : The Quartzose Group, The district in which the above-named group of rocks is prin- cipally developed is that of Tellemarken, in the south of Norway, celebrated by tourists as containing perhaps the most wild and •picturesque scenery in the north of Europe. There exist also northward from Trondhjem, some districts, where the same group seems to prevail, but these cannot be compared with that of Tellemarken, either in extent or economic importance ; nor have Can. Nat. 8 Vol. VII 114 Macfarlanc on the Primitive Formations they been studied or described so minutely * Naumann entitled this district, the Nummedal and Tellemarken Quartz Formation ; Keilhau described it as the Goustafjeld Region, from the mountain which is its most distinguished topographical feature ; while Dahll somewhat indefinitely calls it the Tellemarken Slate Formation. The rocks which constitute this group are the following : 1. Quartzite or quartz slate. This, the most widely distributed rock of the group, occurs in the most multifarious varieties. Pure quartz, with a granular structure and glassy lustre, of con- siderable transparency, and of a white or greyish-white colour, is to be found in beds of great thickness. Fine-grained quartz, with a fatty lustre, and rose-red or flesh-red in color, is also observed in equally powerful beds. The most common varieties are however the splintery, grey, and slightly micaceous quartzites, which are known as quartz slates. Amongst the more impure varieties, talcose, feldspathic, and hornblendic quartzites are to be distin- guished. 2. 3Eca schist, differing considerably in general character from that which occurs in the Primitive Gneiss Formation. The broad- leaved very micaceous variety, with garnets, which is common in that formation, has not been observed at all in this quartzose series. In the constitution of the mica schist belonging to the latter, quartz greatly preponderates, and the rock differs from quartz slate, only in containing a somewhat larger quantity of sil- ver-white or brownish-black mica. 3. Gneiss may be also said to occur in this group, but of a -character widely different from what is usually understood by this term. It is finer grained and less slaty than the characteris- tic primitive gneiss, while the feldspar and quartz, and especially the latter, greatly preponderate in quantity over the mica. This latter mineral, which plays such an important part in the compo- sition of ordinary gneiss, is very little developed, and hornblende is never found replacing it ; so that nothing resembling hornblendic gne^'ss is found in this group. 4. Hornstone and hornstone porphyry , passing into jasper, often occur, and seem to consist of the same minerals, and in the same proportions, as the two last named rocks, but so fine grained that the species are no longer recognizable. The mica schist is seen • According to Keilhau, the district in West Finmark and Quaenanger, in which the Alten Copper Mines occur, belongs to this group. It ia probable also, that another district to the east of the North Cape is of the same formation. in Norway and in Canada. IIS in some places to pass into a grey, coarse, splintery, quartzose hornstone ; while the gneiss gives a red or brown hornstone, with fine splintery, and nearly smooth fractures. 5. Hornblende slate. 6. Talc slate. I. Chlorite slate. 8. Clay slate. 9. Limestone has only been remarked at one place in the whole group, where a thin bed of granular yellowish-white limestone, occurs in the quartzose gneiss. 10. Greenstone and diorite, composed principally of albite and hornblende, occur in large and important masses. II. Granite does not seem to occur interstratified with the members of this group, but frequently intersects them in the form of veins, and also forms irregular masses. 12. Conglomerates and breccias occur in such quantity, and of such peculiar characters, as to constitute a distinguishing feature of the formation. The whole of the rocks already named as forming part of this group, but especially the quartzites, often contain beds or irregular masses, having the aspect of conglo- merates ; which are made up of fragments of the respectively en- closing rocks, cemented together either by a micaceous or talcose substance. The fragments are more or less rounded, and often of oblong forms ; they generally lie parallel with each other, but very often bear little resemblance to boulders. The rocks just enumerated, form layers, often of enormous thickness,which alternate with each other, forming parallel groups, in which one or the other of them (generally the quartz), predo- minates. The fine and coarse grained greenstones or diorites of the formation, are most generally in layers running parallel with the other rocks. They sometimes however occur as veins cutting these, and more frequently as irregular masses. The greenstone beds are often of great extent, and pass through gradual transitions into the neighboring rocks. A layer of diorite occurs in the parish of Skafse, having a thickness of 1000 feet. In the middle it is granular, but towards each side, it gradually assumes a slaty texture. It has also been remarked of other greenstone layers in the group, that they assume a slaty structure, as they approach the rocks above or below them. Keilhau has the following re- marks with regard to the extent which these greenstone or diorite rocks occupy in the series before us. '* We may obtain a good HB Macfarlane on the Primitive Formations idea of the extent to which this member of the group is de- veloped, fi'om the district west of Bandag Lake. On the road to Mo church, we are surrounded by rugged mountains about 2500 feet high, and these from the bottom of the valley to their sum- mits, consist of the same mass of diorite, which has here a breadth of about two geographical miles." The conglomerates, of which mention has already been made, have such an important bearing on the question of the origin of the primitive slate formation, that I may be excused for inserting here, at length, a translation of Keilhau's description of them. These conglomerates have been observed : 1. above Hjserdal church ; 2. on the road from Fladdal to Manddal ; and, 3. on the road from Guldnaes to Berge, in Morgedal. " The first loca- lity in which the conglomerate quartzites occur in repeated alter- nations with hornblende rock (diorite), has been described by Naumann (Beitrage I, 79). The quartz layers there consist of what often appears to be a very fine-grained micaceous sandstone ; in which harder round or oval concretions, sometimes feldspathic, sometimes quartzose, and sometimes of still more varied natures, are imbedded. The softer cementing matter is frequently worn away, so that the harder masses stand out from the rock, like hemispheres. The smaller and more varied in their nature these concretions (which appear formed exactly like boulders) are, the more talcose the enclosing mass becomes ; whereby the slaty texture of the quarzite becomes undulating and confused." The second of the above mentioned localities is on the Mandcela, a short distance before it falls into the Sillegjord. The bluish- grey, very pure and crystalline quartzite which here occurs, is for a considerable distance around, apparently unstratified, and cannot strictly be defined as quartz-slate. It forms powerful masses, in the midst of which large and indistinctly limited por- tions, are more or less thickly impregnated with small rounded portions of quartz of the most difierent shades of color, from white to red and dark-grey. Some of these are quartz, others jasper, while others resemble hornstone; but all of them, even those which most closely resemble their quartzose matrix, are sharply de- fined, and appear like pebbles cemented into it. The fact that these portions are not arranged as separate layers, but spread out as irregular areas, in the massive and crystalline quartz, is to be regarded as unfavorable to the opinion of the me- chanical origin of these conglomerates." " At the third of the in Norway arid in Canada, 117 above mentioned localities, the conglomerate is also enveloped in a large group of quartzite, which contains besides, only a few isolated masses of greenstone. The perfectly boulder-like con- cretions of the conglomerate bed, which range from the size of a hazelnut, to that of the human head, are here of the same sort of greyish-white splintery quartz, which forms the strata of the whole surrounding group. A few of them only are reddish, and remind one of the jasper-like masses which appear to be gene- rally associated with these conglomerate quartzites. At the Hjaerdal locality, already described, Naumann found whole layers of jasper, close to the conglomerate. The cementing material of the con- glomerate betwixt Guldnaes and Berge is argillaceous, and small in amount ; and is certainly to be regarded as analogous to the small beds of clay slate, which occur as regular layers between the thick quartz strata, at other points in this neighborhood. Al- though the foliation of the pure quartzite is retained in the con- glomerate, which is many fathoms thick, this nevertheless, like that below Manddal, does not appear to occupy any well-defined horizon in the stratification. In place of forming a continuous zone along the strike, it appears rather to be a comparatively short and irregular mass. Occurrences of this sort, which may be regarded as belonging at once to the quartz and to the mica schist, are found to a con- siderable extent on the northwest of Sillegjord Lake. Here, on the boundary of the primitive gneiss formation, at several points where the quartzite begins to replace the mica-schist, we find layers in which the quartz occurs in the shape of long cylinders as thick as the finger, and rounded oflf at both ends, as elongated almond-shaped masses ; or in the form of boulders, im- bedded in a cement of mica schist. Some time since, Naumann directed attention to the fact that the amount of talc contained in the cement is greater, the more the conglomerate is varied in its composition. I have often confirmed this, and have moreover remarked that the talc seems to stand in some intimate connection with these problematical rocks. This may be the reason why they have nowhere been found more fre- quently than on the road between Berge in Brunkeberg, and Qvale in Hoidalsmo ; where the quartz beds are associated with other rocks, and especially with those of a talcose nature. The most re- markable conglomerate of this district, as well on account of its composition, as its thickness, is splendidly exposed in a narrow 118 Macfarlane on the Primitive Formations ravine called Ormebraekjuvet, which cuts across the conglom- erate, inclined at an angle of 70°. A road and a rivulet here pass through the ravine, and the rocks are seen in profile on both sides. In a coarse mass of quartzose talc-slate, sometimes more or less micaceous or argillaceous, different varieties of quartz are im- bedded ; which have the form of small boulders, or are elongated in the direction of the stratification. Besides these, there may be remarked in the slate, a multitude of red and very fine-grained feldspathic concretions, which betray here and there a gneissoid nature, caused by dark mica-like streaks. These feldspathic con- cretions are the more remarkable, since hitherto, no rock far or near,has been discovered bearing the slightest resemblance to them, although their oval form, in some parts, and the fact that they are sometimes bent in the direction of the undulations of the sur- rounding mass of slate, would favor the view that they are pebbles from an older rock. They become still more remarkable when we observe them repeated at very distant points. Exactly similar gneissoid concretions with those of Tellemarken, of which we here speak, have been remarked in the conglomerate rocks of North Trondhjems Amt. The boulder-like fragments in the rock of Ormebraekjuvet, attain the size of a closed fist, and lie usually so near to each other, that they constitute the greater part of the whole rock. Eastward from Holvig, towards Vase, down in Vest- ^orddalen, conglomerate talcose rocks also are found. Here, in a talcose slate, a layer was observed including larger and smaller kernels of quartz, sometimes almond-shaped, at other times more irregular ; and one part, apparently segregations from the slate it- self. The foliated portions of the rock are bent and rolled around these masses. On the weathered surfaces of the rock, these ir- regular, and, as it were, imbedded portions, have a lighter color than the surrounding mass. There is probably some feldspar present in these, as well as in the gneissoid concretions already mentioned, and their lighter colour may be due to kaolin from its decomposition. Southward from Holvig, a layer of similar rock occurs, which belongs to the clay slate." " Conglomerates which belong to the chloritic rocks in this district, are found at various places in the upper part of Vest- ijorddalen, in the neighborhood of the cataract Rjukanfbss. From Vaa3, over and beyond Maristigen, a hard chloritic slate predominates ; which appears often as if it had been torn in pieces, and then joined together again, and which contains other very in Norway and in Canada* 119 curious aggregations. There may be observed masses like s^r-- pentine, portions of greenstone, &c., combined in the most varied manner with the slate ; while many phenomena render this place suitable for a more minute study of these conglomerates." " Farther on, at several points in the neighbourhood of Aamdal, it may be observed that the mica schist contains concretions having the appearance of imbedded fragments, and with an aspect, from which one must believe that it has once been broken up, and its pieces afterwards irregularly joined together. For ex- ample, there is exposed between Aamdal Copper-work and Skafse church, a large area of this character. The rock is a fine slaty quartzose mica schist, which, as if by an internal breaking-up^ has acquired a well marked brecciated structure. Only a few of the recemented pieces have rounded angles, the most of them being sharp-cornered. The whole rock, but especially the frag- ments, contain some feldspar. I will mention one other instance, from which it appears that hornblende schist may also some- times contain fragments of foreign masses. This is the case on Skafseberg, over which the road leads from Mo to Skafse church. Here the concretions are again feldspathic, and even gneissoid, but most of them resemble rather the rudiments of small bent layers or beds, than fragments cemented into the horn- blende schist."* As before remarked, the quartzites or rocks allied to them, such as the quartzose mica schists and gneiss, constitute by far the greatest portion of the group. Next in frequency and extent, the greenstones or diorites may^be placed ; after these the horn- blende, talc, and chlorite schists, and the clay -slates ; and lastly, the conglomerates. Foldings of the strata in the quartzose group, have been ob- served in various places, but they do not approach, in intricacy, to the contortions of the gneiss formation. The strata are seldom found horizontal, and generally have a dip of more than 45° ; although they do not seem, generally, to be so near to the vertical as those of the gneiss formation. The direction of the strike varies much more than in the latter, but parallel groups have been traced upwards of eight geographical miles, on the strike. In some places, an approach to a regular succession of the rocks has been observed, but the particulars related are by no means conclusive. As before mentioned, the scenery of this district is of the most * Geae Norvegica, I. 430. 120 Macfarlane on the Primitive Formations wild and rugged nature. The Fjelds, consisting of quartz rock, sometimes present massive peaks, rising in the shape of terraces one above the other ; which latter form is caused by the outcrops of the highly inclined quartz beds. Goustaijeld itself, is a huge peak, rising to the height of 7000 feet, and presenting from a distance, a peculiar furrowed appearance, the cause of which is thus explained by Keilhau : — "The upper part of Goustafjeld is formed of two varieties of quartzite, one of which is the prepon- derating, and the other the subordinate constituent. The former belongs to the purer varieties of the quartzite, and resists de- composition. In the latter, which easily disintegrates to a coarse sand, particles of feldspar are more or less abundantly disseminated. From that part of the mountain where these rocks are found in situ, which is about 300 feet perpendicularly beneath the sharp ridge forming the summit, going upwards,there is observ- able only a succession of very regular beds, having a dip of from 20° to 30°. The mountain is here so sharply peaked, that the beds crop out, as well on the side of the direction of the dip, as on the opposite side. If now the relations of the rocks were as usual, the feldspathic quartzite would be found to form more or less isolated layers, between the strata of the preponderating rock ; but in place of this, the feldspathic quartzite extends in an entirely opposite direction through the mass of the prevailing rock. It goes right across the strata, and that without in the least (like veins) interrupting the continuity of the several beds, because these otherwise diflferent rocks, at their junction, run into each other, the pure quartz gradually becoming feldspathic. The con- sequence of this remarkable relation is very striking. On account of the feldspathic quartzite being so easily disintegrated, and the pure variety, on the other hand, resisting so well, there are produced, where the former crops out, cuts on the ridge, and fur- rows on the sides of the mountain. On account of the height of the mountain (7000 feet), these furrows remain filled with snow throughout the whole year, and are recognisable from a great dis- tance. Thus GoustaiJ^ld preserves the marked features which distinguish this surprisingly furrowed peak, for those who view it from the heights of Hallingdal or Hadeland." " It is a characteristic trait of this group, as well as of the other sections of the country, analogous with it in geological character, and worthy a mention at the outset, that it is especially well sup- plied with copper ores."* This great prevalence of cop- * Gese Norvegica I, 441 . in Norway and in Canada, 121 per ores has given rise, since the beginning of the 16th cen- tury, to the establishment of six different copper works or mining establishments ; all of which however, with but one exception, that of Aamdal, are abandoned. In describing the various mineral deposits, I shall only refer to those of most importance, neglecting alt ^g etlier the innumerable localities of less value. The mines about to be described are those belonging to the copper works of Guldn^es, Aamdal, flvideseid, Sauiand and Hovindbygden. The deposit on which the Giiklnaes mines occur, is probably the most important of the whole district. It is situated on the southwest side of Sundsbarm Lake, in the parish of Sillegjord, at least 1500 feet above the sea, and inaccessible, unless to the foot traveller. It has the form of a layer, and lies between a bed of quartzite, and one of clay slate. It has a length of about 100 fathoms, and a breadth of about 100 feet, and is composed of a flesh-red and sometimes greenish-white aggregation of quartz, feldspar and talc ; in which purple copper and copper pyrites are more or less abundantly disseminated. The ore is found in irregular nests and veins, quartz accompanying it in the latter. These irregular bunches of ore are frequently found in such quantity, as to render the whole mass of the layer worthy of excavation. There is not much of the rock with finely dis- seminated mineral, and the ore is much more suited for be- ing dressed by means of crushing and jigging, than by stamping and washing. The latter processes were nevertheless those em- ployed when the mines were being worked, and this may partially account for the unsuccessful result. The copper ores occurring here are argentiferous ; the metallic copper resulting from their treatment, containing one per cent, of silver. The mines belonging to the Aamdal copper works are very nu- merous ; the most important of them being HofFnung mine, Naes- mark mine and Mosnap mine. The works themselves, are situated 1 300 feet above the sea,on the river called Vierkselven, in the parish of Skafse ; which is subordinate to that of Mo. Hoflfnung mine lies about 160 feel higher, near the junction of a gneissoid gran- ite, of eruptive origin, with the primitive slates. The two lodes containing the ore, occur on both sides of a layer of hornblende schist ; which varies from two to six feet in thickness, and has a fall of from 50° to 60^ to the W.N.W. They run parallel with the strata, and the lode underlying the hornblende schist is the most 122 Macfarlane on the Primitive Formations important. It has a thickness of from four to thirty inches ; the vein-stone is quartz, and is well filled with copper pyrites, generally massive, seldom finely disseminated. In the deeper workings, the lode almost contains as much purple copper as copper pyrites, with no admixture of iron pyrites, or other mineral, except a little feld spar. The ore, on being excavated, was crushed by flat-faced hand hammers, brought up, by jigging, to 30 per cent., and then smelted or sold. Nsesmark mine is like HofTnung, situated in the immediate neighborhood of the work, on a granite vein, two fathoms thick, which intersects primitive slates. In this vein, (from which also side veins shoot out into the adjoining slates,) there occur, running in a direction at right angles with its line of strike, numerous lodes of from two to six inches thick, filled with quartz and copper glance; the latter containing six oz. of sil- ver per cwt. The granite in the neighborhood of these quartz veins is also impregnated with copper glance , to such an extent, as to make it amply worth stamping and washing. This mine is a most promising one ; is altogether new, and the granitic vein has been discovered at a distance of three miles from it, at Bergland mine ; where it bears copper glance in exactly the same manner as at Nsesmark. The ore from the quartz lodes of this mine was brought up by hand-jigging to 70 per cent., and then either smelted or sold. The finely divided ore was worked by stamping and washing. Mosnap mine is about 10 miles distant from the work, and probably lies 2000 feet above the sea. The rocks in the neighborhood are the gneiss, mica schist, and hornblende schist, peculiar to the quartzose group. The mine itself is situ- ated on a granitic vein,which contains irregular quartz layers. Cop- per pyrites, purple copper, and molybdenite are disseminated through it, bat are more especially associated with the quartz. The vein itself has a thickness of several feet, and were it more conveniently situated, would doubtless be considered a very valu- able deposit. It is only very lately that the ores from these mines began to be treated by crushing and jigging, and then sent to market. They were previously stamped and washed, at least the poorer sorts, and the products were smelted at the works, along with the richer ores. The smelting, however, even after the discovery of a vein of fluor spar, which was used as flux, was carried on but with indiff'erent success, on account of the highly quartzose natures of the ores. After the introduction of jigging, the ores were treated as follows, at the smelting works : — The copper glance from Najsmark was calcined in a reverberatory in Norway and in Canada, 123 furnace, and tlie silver extracted according to Ziervogel's method ; by treating it with water, and afterwards precipitating the dis- solved silver by metallic copper. The lixiviated residue from this process, was then smelted together with the rich copper py- rites and schlichs from the Hoflfnung mine, (previously calcined in a reverberatory furnace), in a small shaft furnace. From this operation, there resulted a slag, very rich in ferrous oxide, which was rejected ; a regulus with 55 per cent, of copper, and a small quantity of coarse copper. The regulus was roasted and again smelted ; coarse copper, and a small quantity of thin regulus being produced. The coarse copper was then refined on the small German gahr hearth. The two most important mines belonging to Hvideseid copper- works, occur in the parish of Hvides, and are as follows : Haukum mine, situated beneath BrokeQeld, in the neighborhood of a powerful granite vein, wherein orthoclase and oligoclase are observable. This vein intersects primitive slates, and is accom- panied by several irregular granitic masse?, on the largest of which the mine occurs. The granite mass is more or less impreg- nated with purple copper, and this is occasionally accompanied by metallic silver in fine threads ; which occur in small cavities, with crystals of laumontite and stilblte. The crystals of laumon- tite form fan-like groups, which are coloured green by the oxyd of copper A very small scale of gold has been found in this mine. The following minerals are also met with : mag- netic iron ore, molybdenite, garnet, epidote, and traces of cop- per pyrites.* Bandag mine is situated on the precipitous south side of Bandag Lake. The surrounding rock bears a strong resemblance to granitic gneiss, but nevertheless diff'ers from it in having a larger quantity of quartz, and, as a consequence, a lighter colour. The ore deposit lies parallel with the stra- tification of this rock, and consists of a granular mixture of quartz, mica, copper pyrites, purple copper, highly argentiferous galena, zinc blende, and a little feldspar. Metallic silver in threads, has also been remarked in this mine. The ores from these, and other mines, were for a considerable time smelted at the Hvideseid works, and although the smelting was ultimately aban- doned, the operation was more successful here than anywhere else in the district, being carried on for a longer time. The Sauland smelting works were built for the copper ores occurring at Guli, in the parish of Sauland, which is subordi- • Dahll, Om Telemarken's Geologic, p. 27. 134 Macfarlane on the Primitive Formations nate to Hjaerdal. The lode, which occurs in a coarse grained diorite, is sometimes of considerable thickness, and consists of quartz well charged with purple copper. Here, too, the smelting was unsuccessful, even more so than elsewhere in the district. The ore deposits near Horindbygden in the parish of Tin, are described by Keilhau,* and are the following: I. Thatof Rodsoe consists of a layer of quartz, containing partly massive and partly disseminated copper glance. The thickness is about three feet, the strike north and south, and the dip vertical. It is traceable over a length of 200 feet. II. That of Daarudberge contains also some copper glance in a quartz bed, two feet thick, but appears less rich than that of Rodsoe. III. That of Vashoed is a quartz layer of six inches thick, with a strike north and south, and con- tains some purple copper. The adjacent rock is full of magnetic iron ore, disseminated, and crystallized in very small octohedrons. A deposit of iron ore has been described by Dahll,f as occur- ring in Nissedal, between the farms Aarhuus and Sofdestad. It appears to be a vein, and runs from north to south over the hill called Grubeaasen. It dips 30° to 50° towards east, and has a thickness of nine feet on an average. It is exposed for a distance of 210 fathoms, between two small valleys. In the deepest por- tion, it consists of magnetic iron ore, but on ascending the hill from both sides, the magnetic ore becomes mixed with iron glance, (specular iron ore); the quantity of which gradually in- creases, .until, at the highest part, iron glance alone is present. The surrounding slates are mica schist, containing a little hornblende, hornblende schist and feldspar, and containing portions having a granular structure. The vein is more distinctly separated from the side rock, where it consists of magnetic ore, than when the iron glance is present. The latter penetrates into the side rock, where it replaces the feldspar. It is thus possible to find hand spe- cimens consisting only of iron glance and hornblende. Quartz and desraine are present in the vein. It is impossible to deter- mine v/ith certainty the age of this deposit, but it is intersected by granite veins. In concluding this description of the quartzose division of the primitive slate formation, and of its economic minerals, as deve- loped in Norway, I think that the following features may be mentioned as characteristic of the group. I. The preponderauce of quartzose rocks ; II. The presence of conglomerates of a pecu- * Geae Norvegica, p. 442. fOm Telemarken's Geologie, p. 31. m Nortvay and in Canada, 12§ liar character ; III. The prevalence of copper ores, of a high per- centage, unmixed with iron pyrites ; the veinstone accompanying them being quartzose, and therefore diflScultly fusible ; IV. The presence of iron glance in the few deposits of iron ore occurring in the group. The equivalent of these rocks in Canada appears to be the Huronian formation. In support of this view I shall avail myself of the minute descriptions of the latter to be found in the Reports of the Geological Survey, and particularly in Sir W. E. Logan's Report on the north shore of Lake Huron. The rocks of the Huronian formation are, by these authorities, described as fol- lows: " The quartzites have sometimes the aspect of sandstones, but at other times lose their granular texture, and become a vit- reous quartz. Not unfrequently the quartzite is thin bedded, and even schistose in its structure, and it sometimes holds a Uttle mica, passing into a variety of mica schist; ** These quartzites often become conglomerate, enclosing pebbles of quartz and various coloured jaspers. These pebbles are some- times arranged in thin layers among fine grained beds. At other times, the conglomerates form thicker beds, which swell into moun- tain masses; including great portions which contain blood-red jaspers in a white matrix, constituting a very beautiful rock. " In addition to these, there are conglomerates of a distinctly diflferent character, belonging to this formation. They are somposed chiefly of syenitic pebbles, held in a grey argillo-arenaceous ce- ment,which is more frequently of a greenish color, from the presence of chlorite. The pebbles, which are of reddish and grey colors, vary greatly in size, being sometimes no larger than swan shot, and at others, boulders rather than pebbles, measuring upwards of a foot in diameter. " The quantities in which they are aggregated vary much. They sometimes constitute nearly the whole mass of the rock, leaving but few interstices for a matrix, and sometimes on the contrary, they are so sparingly disseminated through con- siderable portions, as to leave spaces of several feet between neighboring pebbles ; which are still, in such cases, often several inches in diameter. With the syenitic pebbles, are occasionally associated some of diflferent colored jaspers. The matrix ap- pears often to pass on the one hand, into the grey quartz rock, by an increased proportion of the arenaceous particles ; and on the other, into a thin bedded greenish fine grained slate, which is 126 Macfarlane on the Primitive Formations sometimes very chloritic. In a third form, the matrix is scarcely distinguishable from a fine grained greenstone In the slate, the stratification is often marked by slight differences of color, in the direction of which, it is occasionally clcavable. The bands in other instances, are firmly soldered together, but in both cases, joints usually prevail, dividing the rock into rhomboidal forms, which are sometimes very regular." These slates sometimes approach to argillites, but often, through the chloritic varieties, appear to pass into greenstone or diorite, which, in its typical form, consists of a greenish white feldspar, with dark green or black hornblende. The feldspar is sometimes however, more or less tinged with red, and the rock then occa- sionally appears to pass into a kind of syenite, by the addition of a very sparing amount of quartz. These two forms of the rock are generally highly crystalline, and not very fine grained. The greenstone, however, sometimes displays a fine texture ; and in such cases it frequently holds much disseminated chlorite, giving it a very decided green colour. Portions are found, containing so great a proportion of the mineral, as to yield with facility to the knife. Associated with these, are three bands of impure limestone, often silicious and sometimes dolomitic, the uppermost one of which, is interstratified with a large amount of hornstone, in very regular beds. The total thickness of the formation on Lake Huron, is estimated about 18,000 feet; of which more than 10,000 feet are quartzites, including the jasper conglomerates. 900 feet of the remainder are hmestone and hornstone bands, and the remainder the slate conglomerates, with chloritic and epidotic slates the whole being interstratified with diorites. While the great mass of these greenstones or diorites, are sup- posed to be altered sedimentary beds,there are other greenstones, which, as well as certain granites in the formation, are evidently intrusive. The most important mineral deposits of the Huronian series are the copper lodes at the Bruce, Wellington, and Huron Bay mines. The ores are here yellow and purple sulphuret, in veins, of quartz, which cut the diorites of the region. According to Sir W. E. Logan's careful examination of the Bruce Mines, made in 1848, about 3000 square fathoms of the lodes were computed to contain, on an average, 6^ per cent, of copper. Since then, about 9000 tons of 18 per cent, ore have been raised from the mine, which has been opened to a depth of 50 fathoms. Attempts i7i Norway and in Canada, 127 were made to smelt the ores, in a furnace erected on tlie spot, but they are now shipped to Great Britain or to the United States. The adjacent mines appears to be yielding even larger quantities of ore than the Bruce. Copper mining has been attempted also at Root River, at Echo Lake, and in many other localities in this formation ; which, like its Norwegian equivalent, appears to be eminently cupriferous. At the Wallace mine on Lake Huron, copper pyrites occurs, with an arsenical snlphuret of nickel, but the deposit has not been much examined. In the same vicinity, Mr. Murray has described a bed of specular iron or red hematitic ore, and he has shown that the immense deposits of this ore now so extensively wrought at Marquette, in Northern Michigan, be- long to the Huronian formation. From this sketch of the Huronian formation I think it will appear evident that the same particulars characterize it as the cor- responding group in Norway, viz: L The preponderance of quartzose rocks. H. The presence of conglomerates of peculiar character. HI. The occurrence of great masses of interstratified diorites or greenstones. IV. The beds of hornstone or chert. V. The presence of copper ores of a high percentage, unmixed with iron pyrites ; the veinstone accompanying them being of quartzose. VI. The presence of iron glance (specular iron ore) in the few deposits of iron ore occurring in the group. In the absence of organic remains, it seems to me that the only means left of identifying the same group in remote localities, is to compare minutely their petrographical and other physical characters. If this view be correct, there can be little doubt but that the quartzose division of the primitive slate formation in Norway, and the Huronian formation of Canada, are identical. In conclusion, I have to remark with regard to the development of the mineral resources of both formations, that more appears to have been accomplished in this respect in Canada, than in Norway; seeing that the copper mines on the north shore of Lake Huron have had more permanency than those of Tellemarken. Greater progress is probably attributable only to the greater amount of capital which has been invested in the former mines. The ob- tacles met with have been substantially the same in both coun- tries : the remoteness and inaccessibility of the region from the ordinary markets, and the difficulties in the treatment of the ores. These however have been overcome in this country, and the prin- cipal mines on Lake Huron are now well established, and pro- fitably wrought. 128 New Spectrum ditcovmes.

XII. — An account of the Botanical and Mineral pro- ducts^ useful to the Ckipewyan tribes of Indians, inhabiting the McKenzie River District. By Bernard R. Ross, H.B.CS. (^Read before the Natural History Society of Montreal.') A nation of hunters, paying no attention whatsoever to agri" culture, can enjoy but few of the numerous benefits aflforded by the vegetable kingdom to the human race in general. Such is the condition of the Chipewyan tribes of Indians. Though the benefits derived from the inighty forests which fill the Mackenzie valley, are but few to their denizens, they may be considered not- withstanding their fewness, to be of essential, indeed of vital im- portance to the existence of the aboriginal dwellers in these wilds ; since without fuel to warm them, and without canoes to migrate, they would soon cease to exist. From the vegetable kingdom are derived fuel, canoes, sleds, paddles, snow-shoes, baskets, dyes and food, besides other articles which will be noticed hereafter. Two trees, the canoe birch (^Betula papyracea) and the white spruce (^Abies alba) stand out, ^rom their importance, in bold relief; but the larch and willow are used also, as well as several kinds of plants,which furnish medicines, dyes, and edible berries that are useful in periods of scarcity. Indeed in summer, a considerable portion of the ordinary food, as well as the luxuries of the natives, is drawn from this source. According to the method adopted in my former paper on the zoological products, I shall pass the various uses of each species briefly in review : — The Canoe or Paper Birch (Betula papyracea). — The benefits which this valuable tree confers on the inhabitants of the McKenzie River District, are many and important. Its baik is used in the construction of canoes, and in the manufacture of various utensils for domestic use, such as drinking cups, dishes, and baskets. It also yields spunk or touchwood of the best quality. Of its woodi platters, axe-helves, paddles, snow-shoe-frames, dog-sleds and other articles are made, and as it is a strong and durable material, of close grain, and susceptible of receiving a tolerable polish, the white residents avail themselves of it for the construction of furni- ture. In spring, the sap forms a pleasant drink, from which a syrup can be manufactured by boiling, and which may be further transformed, by fermentation, into an agreeably flavoured wine of considerable potency. Beyond the arctic circle, the birch is rare ^♦« > i ^m Useful to the Chipewyan Tribes of Indians, 135 Mineral Products. The mineral kingdom affords but few and unimportant articles for the necessities of the Indians. Sulphur is found in considerable quantities at the Sulphur Cove on Great Slave Lake. Here sulphur springs occupy a space of several hundred yards in length along the beach. They are very clear, and flow in small rivulets, whose banks are encrusted with a deposit of sulphur which becomes serviceable when thoroughly dried, and is used by the Chipewyan Indians who come to Fort Resolution, in the fabrication of matches. Common Salt is procured from the salt plains lying about 20 miles up the Salt Elver, a tributary of the Slave. The springs is- sue from the base of a long ridge, some hundreds of feet in height, and spreading their waters over a clayey plain, deposit the salt by evaporation in cubical crystals of various degrees of fineness. The mother liquor flows into Salt River, giving a name as well as a most abominable taste to that stream, which is still sensibly brackish at its junction with the Slave. At present, the main supply of salt is confined to one large jet d^eau from which a strong brine, mingled with completely formed crystals, is perpetually thrown. Around this spring, evaporation has formed a hillock of dry salt many feet high ; and a pole forty feet long was shoved into the spring without finding boltom. Sir John Richardson considers that these fountains belong to the Onondaga Salt group of the Upper Silurian Series of New York. Numerous bands of buffalo, elk, and reindeer frequent these plains to lick the mineral, of which they are extremely fond* The salt is of excellent quality, strong and well-flavoured. It preserves meat, meal, and butter, fully as well as that imported from England, being far superior to the description manufactured in the plain country of the Swan River District. As the Salt River is very crooked, with generally too litt.le water to float any craft larger than a small canoe, the transport of the salt from the springs to its mouth is by horses. Ochres, red and blue, are procured at several points in the Dis- trict, and are ueed for painting snow-shoes and sleds, by the na- tives. The Loucheux of the Youcon River paint their faces with these colors in the same way as the tribes of the Plain. White earth or Pipeclay is found associated with the coal beds at the mouth of Bear River. When newly dug, it is plastic, but 136 Ross on the Botanical and Mineral Products soon dries. It is eaten in times of scarcity by the natives, and is also used as a soap for washing their clothes, and by the whites for white-washing their houses. At the request of Sir John Richardson it was analyzed by Drs. Davy and Prout, but was not found to contain any nutritious matter. Mineral Tar is procured at several spots along the Arthabaska or Clear Water River ; it is also found on Great Slave Lake, at a short distance N. E. of Big Island, and also near to Fort Good Hope. It is little used by the natives, except to mix with and to soften gum f « r paying canoes with. It becomes, after being boiled and purified, an excellent tar for boat-building purposes, for which it is used. Iron Pyrites is found in the Mountain Ranges. The Gens- des-Bois, a tribe living on the banks of the Pelly River, use it instead of flint to strike fire with. Pieces of Agate are used occasionally as flints, and native cop- per has been made into knives, spear and arrow heads. Lignite exists in large quantities near the mouth of Bear River where it is seen in a state of combustion. It is of little value as fuel, and quite unserviceable for forge use. The legend told by the Slave and Dog Rib Indians, of the origin of the fire in these lignite beds is rather curious. The story relates that in the days of old, before Indians roamed the forest, or glided over the waters in their birchen canoes, a giant, tall as a pine tree, dwelt at the east- ern end of Slave Lake, then a much larger sheet of water. The giant hungered and he went to hunt. His spear was a tall fir-tree, hardened in the fire, and tipped with native copper. The skins of gigantic elks served him for clothing. Travelling on, he found a beaver-house ; the beavers in those days were of extraordinary size, and their houses of corresponding proportions. With great exertion and toil, the house was broken open : it contained two animals, a female and her young. The latter was killed, but the dam escaped, pursued by the giant, who bore the dead cub over his shoulder on the point of his spear. On they sped, until the western end of the lake was reached, where a rocky barrier then stretched across. Through this, the beaver pushed her way, giv- ing vent to the waters of the lake, and thus forming the Tess- chi or McKenzie's River, the flood of which swept her down- wards, far out of the pursuer's reach. The giant still continued the chase, until hungry and exhausted, he reached the mouth of Bear River, where he stopped to cook the cub, which was the Useful to the Chipeivyan Tribes of Indians. 337 size of a moose- deer ; and thus lit the fire which continues burning to the present day. With these I think I have completed this series of notes, in which I believe that nothing of importance to the comfort or wel- fare of the natives omittt^d. Among the Eskimos, the arts and manufactures of savage life are in a much more advanced state than among the Indian tribes, and I trust that I shall, at some future period, have the gratifica- tion of laying an account of them before the Natural History So- ciety of Montreal.

In the numbtf of this Journal for December last, there is a votice of one sheet of Prof. HalFs recent Report on the Geology of Wisoonsui. On the 12th of March, 1862, two copies of ihe same rqwrt were received at the office of the Geological Survey of Canada, by maiL Both of these are dated January 1, 1891. On one of the copies there are indoised with pen and ink the On date of Report on Geology of Wisconsin, 157 words, "Published Nov., 1861." I do not recognize the hand- writing, but it is evident that one of the dates must be incorrect, and I believe both are. I have some evidence that the report was not published until about the middle of December, 1861, eleven months after the date printed on the cover, and I am obliged to call attention to it for the following reasons : On the 21st of November last, I pubhshed a paper containing descriptions of a number of new species of fossils, principally from the Potsdam sandstone and other associated formations. On the 22nd I sent a copy to I'rof. Hall by mail. In the January No. of SilHman's Journal, he alludes to it in his letter on the Pots- dam sandstone, and Hudson River rocks of Vermont. As a gen- eral rule, articles intended for that Journal must be in the hands of the pubHshers about one month previously to the date of pub- lication. It seems quite certain, therefore, that my paper was in Prof. Hall's possession in the latter part of November, most pro- bably about the 24th of the month. In my paper I described a new genus of fossil Brachiopoda under the name of Obolella, One of the species to which I referred as exhibiting the characters of the genus, occurs in the Potsdam sandstone of Wisconsin, Prof. Hall has described this species on p. 24 of his report, under the name of Lingula polita, and has also pointed out that its characters are not the same as those of either Obelus or Lin- gula. His remarks are in substance the same as mine except that he notices an " obtuse dental process on each side of the rostral cavity," which is not visible in any of our specimens. On comparing the two papers any person would be justified in sup- posing that I had taken the idea of the genus Obolella from Prof. Hall. Thus by antedating his report eleven months, he lays me open to the charge of plagiarism, which is certainly very unfair. I never saw his report, nor had any knowledge of its con- tents, nor of its existence, until I saw the notice of it in this Journal in the beginning of February, 1862, at which time the December number was issued, — more than two months after my paper was distributed, and fourteen months after the time he has given the public to understand that his was published. I am com- pelled, therefore, in self-defence, to correct his erroneous date. Some of my scientific friends have advised me to take no notice of this and similar matters. They, however, are engaged in dif- ferent fields of research from that occupied by Prof. Hall and myself, and as they cannot come into collision with him, thev can 158 Reviews and Notices oj Booh, look upon these affairs with the most stoical composure. Were they in my position, they would soon feel their magnanimity very sensibly diminished, and rapidly oozing away from them. For the last four years I have been subjected to great annoyance in consequence of Prof. Hall's extraordinary practice of antedating his publications, and I have a perfect right, and shall not hesitate on every occasion, to resist in the most public manner.

London, 1861. Longman & Co. 12 mo, pp. 271. *"The author of this work is already favourably known by his " Manual of Protozoa," with a general introduction on the Prin- ciples of Zoology — which is an excellent text-book for students. The present volume is an abiidgraent of a larger work, which the author hopes ere long to publish. The Ccelenterata include such animals as the Hydra, Sertularia, Medusa, Actinia, and Zoophyte. They are all furnished with an alimentary canal, freely communi- catino- with the general or somatic cavity. The substance of the body consists essentially of two separate layers; an outer, or ec- toderm, and an inner, or endoderm. These two membranes, but especially the former, are in general provided with ciliae. In the integument of those organisms we constantly meet with peculiar thread-cells, which, when they come into contact with the human skin, frequently produce disagreeable stinging sensations. The sub-kingdom is divided into two orders : — 1. Hydrozoa^ixi which the wall of the digestive sac is not separated from that of the so- matic cavity, and the reproductive organs are external ; 2. Acti- nozoa, in which the wall of the digestive sac is separated from that of the somatic cavity by an intervening space, subdivided in- to chambers by a series of vertical partitions, iu the faces of which the reproductive organs are developed. The author gives the morphology, physiology, classification, and distribution as regards space and time, of the animals included in these two orders. The facts are stated in a clear and interesting manner, and are Reviews and Notices of Booh. 159 illustrated by numerous excellent woodcuts. The author has given the most recent observations in regard to the anatomy and physiology of the animals, and has produced a manual of great value to the student of zoology, to whom these lower types of animals must ever present attractive subjects for observation. Physiology is indebted in no small degree for its progress to the labours of naturalists who have made researches into the functions of these animals, and we do not know any department of natural history more deserving of attention. Much has been done of late years in the illustration of the various divisions of the Ccelenterata by Forbes, Allman, Huxley, Hincks, Busk, Strethill, Wright, Gosse, Agassiz, Sars, Siebold, Steenstrup, Miiller, Milne-Edwards, Gegenbaur, Leuckart, and others. We have much pleasure in recommending Mr. Greene's work as an excellent epitome of all that has been done by these authors. There is a valuable biblio- graphy appended, along with a series of questions which are well calculated to test the student in regard to his knowledge of the subject." — Edinburgh New Philosophical Journal. Scripture and Science not at variance; with RemarTcs on the Historical Character^ Plenary Inspiration, and Siirpassing Importance of the Earlier Chapters of Genesis. By John H. Pratt, M.A., Archdeacon of Calcutta. 4th Edition London: Thomas Uatchard. 1861. 8vo, pp. 158. " It has often been said that the discoveries of science are at variance with the statements of Scripture, and it is sometimes diffi- cult for those who believe in the inspiration of the sacred volume to repel the charge made against it by sceptical men of science. The object of Archdeacon Pratt's work is to present such persons with a reply in a concise and portable form. It points out the difficulties to be met with and the objections to be removed, and tends to strengthen the faith of those who believe the Word of God. The author gives instances in which Scripture and science were supposed to be antagonistic, but which were cleared up by subsequent discoveries. He then enters on an examination of the earlier part of the Book of Genesis, and concludes that no new discoveries, however startling they may appear at first, need dis- turb our belief in the plenary inspiration of the sacred volume, or damp our ardour in the pursuit of science. The vexed questions in regard to the six days of creation, the origin of man and of 160 Reviews and Notices of Booh. species, of death before Adam, the nature of the Deluge, the ori- gin of languages, are ably handled. Many apparent discrepan- cies are explained, and several false theories are exposed. The author writes as a man of science, and at the same time a believer in the Bible ; and he supports his views by able and judicious arguments. " The hasti/ and immature deductions of science may sometimes stand in opposition to Scripture ; but their settled results, in which the body of philosophers agree, often confirm and illustrate the statements of the inspired Volume. Let us then hold firm oui' grasp upon this truth, that the Scriptures are the infallible Word of God, true in every statement they contain, although the interpretation sometimes demands more knowledge than we at present possess ; but let us at the same time remem- ber, that there is no ground whatever for ceasing to pursue science, in all its branches, with an ardent and fearless mind. God's Word and Works never have contradicted each other, and never can do so. The progress of science in inevitable, and it is the glory of man's intellectual endowments. It is the setting forth of the greatness and wisdom of the Creator in His works. Let us therefore push on investigations to the utmost with untir- ing energy. We have nothing to fear. The greatest perplexities may at any time surround us ; but both reason and experience have armed us with arguments which assure us that all will be right. Whatever happens, let our persuasion always be avowed, that Scripture cannot err. Let us be content rather to remain puzzled, than to abandon, or even question, a truth which stands upon so immovable a basis." — Edinburgh New PhilosopJiical Journal, Erratum. — On Page 8*7 last line, for " Plectrophanes nivalis' read *^ Fringilla nivalis^ Wilson," MONTHLY METEOROLOGICAL REGISTER, ST.

ARTICLE XVI. — On the Primitive Formations in Norway and in Canada^ and their Mineral Wealth. By Thomas Macfarlane. ( Continued from page 1 2 7. — Conclusion.) II. The Primitive Slate Formation. B : The Schistose Group. The second or schistose division of the Primitive Slate Forma- tion in Norway, may be said to exist, with certainty, in two dis- tinct areas, the one to the northeast and southeast of VestQord, in the Nordlands, and the other to the northeast, west, southeast, and south of Trondhjem. Keilhau describes the former of these re- gions as " The Mica Schist districts of Tromsen and Senjen." The latter region he includes in what he entitles " The Norwegian portion of the central transition territory of the Scandinavian Peninsula," because it appears, through transitions, to stand in intimate connection with the fossiliferous Silurian strata, which are developed around the northern end of Mjosen Lake. Be- lieving however, with Naumann, that although the division line between the two formations, may sometimes become very indis- tinct, nevertheless, "on careful examination its existence will be found in most cases, capable of demonstration," I have assumed, with him, that the strata of the last mentioned region belongs to the Schistose Group of the Primitive Slate Formation. The rocks of which they are composed are given in the fol- lowing list, in the order of the frequency of their occurrence. Can. Nat. 11 Vol. VII 162 Macfarlane on the Primitive Formations 1. Mica schist, " a slaty crystalline mixture of mica and quartz,"* occurring most frequently and characteristic in the dis- tricts of Tromsen and Senjen. It is, however, often found of a more equivocal character, and is then called micaceous schist. It presents numerous transitions into the other schistose rocks of the group. Thus, gradually becoming fine-grained, it passes into clay slate, micaceous clay slate, or argillaceous mica schist, and by the disappearance of the mica, through quartzose mica schist, into quartz slate. Similarly, when chlorite and talc occur in it, it often becomes a chloritic or talcose mica schist; the former of these being the most frequent. 2. Clay slate, " an impalpable (indistinctly mixed,) distinctly fo- liated, soft rock ; generally of a greyish, greenish, or bluish col- or,"! appears to be, next to mica schist, the most frequently occur- ring rock. It is however, more developed in the districts around Trondhjem, and is of a more variable character than even the mica schist. Besides the many varieties that may be included under the general term of argillaceous slate, which is frequently applied to these rocks, there occurs a clay slate, described as be- ing both micaceous and chloritic, (Chloritischer Thonglimmer- schiefer) ; from which it appears that, even mechanically, the same substances are distinguishable in some clay slates, which Sauvage found by chemical analysis to be present in the slates of the Ar- dennes ; viz., a chloritic mineral which was decomposed by hy- drochloric acid, with a micaceous mineral decomposable by sulphuric acid, and quartz.]; 8. Chlorite schist, " a soft schistose, mostly greenish colored rock, consisting principally of chlorite. Quartz or feldspar, or both together, are however frequently mixed with the chlorite."|| It is often found in its characteristic form, but is also frequently described merely as chloritic schist, and occurs principally in the districts around Trondhjem. 4. Limestone comes next in frequency. It is developed especially in the districts of Tromsen and Senjen, where its texture varies from granular to impalpable, and its colour from white to dark grey. The limestone of the districts around Trondhjem, is mostly yellowish-white, and of an impalpable, sometimes slaty structure. ♦ Lehrbuch der Geogaosie II, 281. t Gotta : Gesteinslehre, p. 140. j Idem, p. 147. i Ann : des Mines VII, 441. II Gotta : Gesteinlehre, p. 145. in Norway and in Canada, 163 5. Quartz slate and Quartzite, appear as transitions from mica schist, in the manner above referred to. 6. Gneiss, more or less characteristic, occurs in the group, es- pecially towards the junction with the Primitive Gneiss Forma- tion. 7. Hornblende schist, occurs in the Trondhjem region, and also in more northern districts. In both, it is connected with, and forms transitions into diorite. 8. Diorite and other Greenstones. Diorite is " a crystalline, granular mixture of hornblende and albite, sometimes also slaty or porphyritic."* Most of the greenstones in this group seem to be diorites. They are, however, often of very variable characters, and by the substitution of diallage for hornblende, graduate into a species of diabase. 9. Granite and Syenite, are also eruptive rocks occurring in the group, sometimes intimately associated with the diorites. Hornhlendic granite, a connecting link between granite and syen- ite, and granulite are also mentioned. 10. Serpentine sometimes occurs in considerable masses. It is confined to the schistose districts south of Trondhjem, and con- sists of the common dark-coloured variety, differing altogether from the light coloured serpentines of the Primitive Gneiss For- mation. Chromic iron ore invariably accompanies it. 11. Euphotide; a rock thus named is described by Keilhau, as containing large grained diallage or hypersthene. This is however a feldspathic rock, and by reference in a note in a for- mer portion of this paper, p. 17, it will be seen that it is to be regarded as a kind of diabase, and distinct from the true eupho- tides of the Alps. 12. Talc schist. 13. Steatite or Soapstone. This, together with the rocks yet to be enumerated, is of comparatively rare occurrence. 14. Dolomite. 15. Conglomerates and breccias, somewhat resembling in char- acter those already described in the quarztose division of the schistose formation. The rocks above enumerated form, as already mentioned, two distinct geographical regions, which differ also in petrographical characters. The first is the one already mentioned, of Tromsen * Cotta : Gesteinlehre, p. 57. 164 Macfarlane on the Primitive Formations and Senjen, where the preponderating rock is mica schist ; with which limestone, more or less granular, is very generally inter- stratified. Besides these, more or less characteristic gneiss, horn- blende, chlorite, and talc schist occur as subordinate constituents. Well-defined clay slate is of comparatively rare occurrence, aj- though the mica schist often assumes an argillaceous character. The second region is that spread out to a considerable distance, in the directions before mentioned, around Trondhjem. In this also the mica schist may be termed the preponderating rock, but the jnterstratified limestone is less frequent. Moreover clay slate and chloritic schist are of far greater frequency than in the first named district, as is also serpentine ; which latter rock may be said to be characteristic of the second district, especially of that part of it which constitutes the Dovrefjeld Mountains. The serpentine masses seem to be irregularly in terst ratified with the slates, and sometimes to graduate into them. The greenstones and granites, besides occurring in distinct beds, often form irregular masses and regular veins, intersecting the schistose members of the group. Here, as in the two groups of rocks already described in this paper, these crystalline rocks, as they approach their limits, gra- dually assume a schistose structure. Not only does " the green- stone, in this way, change into hornblende slate or greenstone slate, and the granite become gneissoid, but the greenstone is found even to graduate into mica schist and clay slate. The more purely granular the greenstones are, the more does the form of the deposit deviate from that of a layer or bed. Various subdivisions or zones have been distinguished in this group, which greatly difi"er in their general strike. The principal zone of the Dovre^eld Mountains, seems to run E.N.E., which is also about the direction of the Dovre^eld range. The dip varies much, but seems to be, on an average, about 45'^. To judge from the direction of the dips given on the geological map, vari- ous folds occur in the strata, from their junction with the primi- tive gneiss, to where they graduate into fossiliferous beds. In the country south of Trondhjem, the mountain masses of Dovrefjeld and Fillefjeld, consist principally of the micaceous, ar- gillaceous, and chloritic schists, already referred to. They con- stitute ns it were, the pedestal for the higher peaks of these ranges, such as the Jotunfjeld. These peaks are generally of igneous rocks. The Faastenen are, however, composed of serpen- tine, and Snehsetten, of a peculiar sort of gneiss. in Norway and in Canada, 165 The most important mines of the district south of Trondhjem, are the copper mines of Roraas and its neighborhood, the chrome mines on the Dovrefjeld, and the nickel mines of Espedal. The rocks around Roraas consist of micaceous slates, partly chloritic, and partly argillaceous. They graduate into glossy clay slates, and are sometimes described simply as green slates. These frequently assume the character of fahlbands, being impregnated with pyritous minerals, and weathering red. The deposits of Roraas, which have been worked since 1744, seem to partake of this nature. They form layers in the slates, varying from one to fourteen feet in thickness ; the whole of which, however, by no means consists of cupreous minerals, but usually of many small pyritous beds, lying side by side ; these being again divided into smaller ones, separated from each other by scales of chlorite schist. The preponderating ores are copper pyrites, and iron pyrites, which are sometimes mixed with magnetic pyrites and zinc blende ; while chlorite, brown mica, quartz, garnet, actino- lite, and asbestos, also accompany the metallic sulphurets. The ores, as they are delivered to the smelting houses at Roraas and Foldal, average only five per cent., and frequently are as low as three per cent. They are roasted in heaps, and then smelted to reg- ulus in shaft furnaces ; little or no flux being required. The result- ing regulus is roasted repeatedly upon hearths, (stadeln) and again smelted, when black copper is obtained, which is refined on the small gahr hearth. The copper is principally sold for home con- sumption, but part is also sent to the Hamburg market, where it is known as " Drontheimer" copper. The chromic iron mines of Roraas in Sundal, and in Lessoe, have been, and still are wrought with very considerable success. They all occur in serpentine, and in one year as many as 100 have been worked. Some of these are large and regular deposits, and others are of less extent. The most important of them are situ- ated in the districts to the east of Roraas, Rohararaerne, and Fer- agsfjeldene, and are owned and worked by the proprietors of the chromate of potash manufactory at Leren. Three different sorts of ore are produced at the mine, : No. 1, the best, which is exported to England, although its content in chromic oxide is much beneath what is usually contained in the Baltimore ore; No. 2, an inferior sort, which is worked up into bichromate of potash at Leren ; No. 3 is a still poorer quality, which is stamped and washed, the products being also used in the manufacture of 166 Macfarlane c the Primitive Formations bichromate. At the macractory, the ore in fine powder is simply ignited in a reverberatorfarnace, with about 30 per cent, of cal- cined potash, and little o no saltpetre. The resulting mixture yields, on lixiviation witlwater, a solution of neutral chromate of potash, which separates t^a granular salt on evaporation. It is redissolved, and the soluon is treated with a certain quantity of sulphuric acid, when (ystalli zed bichromate of potash is ob- tained. The sulphuric aci is manufactured in the same establish- iwent. One hundred pariof ore yield about thirty-seven of bi- chromate, so that the oraised must contain only about twenty per cent, of chromic oxk. The nickel mines of E«dal, which are now abandoned, fur- nished an ore much of theame character as those of Ertelien in Ringerike, described in th4irst part of this paper. The mode of treatment was also similar The rocks of the two a«as just described, offer, as we have seen, very considerable ihological differences. Those of the northern region do not spear to present any striking resem- blances with the Canadianocks, but the region about Trondhjem strongly resembles that of le Eastern Townships of Canada, and garees with it in the very pnts in which it differs from the mica schist region of Tromsen ai Senjen. Among these are the pre- dominance of clay slates, it presence of serpentines, with chro- mic iron, and the occurrem of ores of copper disseminated in the schists. These rocks i Eastern Canada have been traced from the line of the state o Vermont, for 140 miles north-east- ward to the Chaudiere Rivf, and thence, at intervals, as far as Gaspe. As described in tL Reports of the Geological Survey, they consist in great part oniica schists, passing into a gneiss, sometimes granitoid, on the ne hand, and into clay slates on the other. Roofing slates are amdant in this series, and beds of steatite and chlorite slate ai not uncommon. Quartzites, some- times conglomerate, are me'>vith, and hmestones, which are very often magnesian, and weatsr of a reddish or brownish color from the presence of iron orianganese. They are sometimes re- placed by carbonate of nifioesia. Beds of serpentine are art important feature in this sera ; they are often mingled with lime- stone, dolomite or magnese, and always impregnated with chrome and nickel. These irpentines are sometimes associated with diallage and with feldsp.hic rocks, which constitute varieties of diorite and diabase. Thei same rocks are traced southwards .ix, m Hg^ in Norway and in Canada. L67 in the Green Mountains, through a large part of the United States^ All of them find representatives in the Norwegian group around Trondhjem, and in the Dovre^eld, This resemblance is still further traced in the metalliferous deposits of the two regions. In the Eastern Townships of Can- ada, copper sometimes occurs in the native state, in clay slate, but much more frequently in the form of yellow and variegated sul- phurets, or of copper glance, disseminated in micaceous or chloritic slates, or in limestone. These deposits are of the nature of fahl- bands. Those of Sutton and Ascott, especially the latter, have a. strong resemblance to that of Roraas. The copper ores of this re- gion are generally subordinate to the stratification. The short, and irregular veins of quartz and bitter-spar, which traverse these copper-bearing strata, sometimes however carry rich ores of cop- per, occasionally with gold. Iron schists, which consist of scaly peroxyd of iron, intermin- gled with various proportions of quartz and chlorite, constitute important beds of iron ore in some parts of this series, as in the townships of Brome and Sutton, where they were formerly wrought to a small extent. These schists resemble the itabirite of Brazil. Chromic iron accompanies the serpentine in Canada, as in Nor- way. The deposits of this ore occurring in the townships of South Ham, Bolton, and Melbourne, greatly exceed those of Nor- way in richness and extent. The deposit in the first named township has been worked, producing an ore containing forty- three per cent of chromic oxide. As far as regards the developement of the mineral resources of the group, Norway is in advance of Canada. Not only has the mining of copper and chrome ores been long established, but the manufacture of the valuable products obtainable from these, has been long and profitably pursued. The mines of Roraas are be- ginning to sufi"er from the scarcity of fuel at the great height, (2080 feet above the sea,) and the chrome mining and manufacturing has had to contend with expensive cartage, and often with high prices for potash, which is to a great extent imported from Russia. In Canada, around the mines of the Eastern Townships, the settler destroys acres of timber, the softer sorts of which he might burn to charcoal ; and manufactures tons of potash, which the chrome miner might buy, and use to manufacture his ore into chromate of potash, at a rate alike profitable to producer and con- sumer. I am not aware of any district where greater advantages 168 Macfarlane on the Primitive Formations exist. May they soon be appreciated, and taken advantage of, as they deserve. These crystalline rocks in the Eastern Townships are re- garded by the Geological Survey of Canada, as a meta- morphosed portion of the Quebec group, which belongs to the inferior part of the Lower Silurian series. This view of their age coincides somewhat with that of Keilhau, relative to the similar formation around Trondhjem, which according to him " appears, through transitions, to stand in intimate connection with the fossiliferous Silurian strata." In the foregoing, I have endeavoured to compare in their pe- trographical and economic relations, the three groups of rocks mentioned at the commencement of this paper. It was not originally my intention to pursue the subject farther than this ; but seeing that the comparison which I have endeavoured to in- stitute would be incomplete without some reference to the mutual geological relations of these groups in Norway, I oflfer the follow- ing remarks before concluding. The oldest of these groups is the Primitive Gneiss formation. This at least was the opinion of the older geologists, such as Nau- mann, Keilhau and others, who specially studied the saviour Scandinavian formations, but Kjerulf and Dahll, to whose re- searches I have yet to refer, have lately declared themselves op- posed to this view. According to Keilhau, the gneiss formation of Kongsberg and of Flesberg, is, to the east of these districts, con- formably overlaid by the Tellemarken quartzose group, into the rocks of which the gneiss forms a gradual transition. The same relations are described by Keilhau, as occurring at other points of junction, and he concludes that the Tellemarken quartzose group is to be regarded as filling up a very broad depres- sion in the underlying gneiss formation. The quartzose group is not found in contact with any of the schistose series described, but the analogous quartzose group of Alten and Quaenanger is overlaid conformably by the mica schist rocks of Trorasen and Senjen. The relations of the latter to the DovreQeld slates are unknown, for wherever the last mentioned come in contact with strata belonging to the primitive gneiss formation, both the quartzose and mica schist groups are absent, and the slates of Dovrejeld rest conformably on the gneissoid strata. On the other hand, these Dovrejeld slates form a continuous transi- tion, through less and less crystalline slates, grey wa eke slates, and in Norway and in Canada, 169 sandstones, into the fossiliferous Silurian strata of the district north of Mjosen Lake. It seems therefore that the succession of these groups, in the order of their antiquity, is as follows : — 1. Primitive Gneiss formation^ 2. Quartzose ffroup. ") ^ . . . ^ Z' ( Primitive Slate 5. Micaceous group. > 4. Argillaceous and chloritic group. ) 5. Greywacke slates, sandstones, and limestones. 6. Fossiliferous Silurian strata. It is to be remarked, that besides these stratified groups, various ■eruptive formations occur, whose age or place in the above list it is difficult to determine. Among these, the gneiss-granite of Vest- flord, and the granite and gneiss-granite in the southern parts of Bratsbergs Amt are the most important. The relations of the latter to the Tellemarken quartzose group, have been minutely investigated by Dahll, and described in his paper " Om Tellemark- ens Geologie." He there unequivocally establishes the following succession, commencing with the more modern formations. 1. Syenite with associated granite, rhomboidal porphyry and augite porphyry. 2. The Devonian formation. 3. The Silurian formation. 4. Gneiss-granite and granite. 6. The slate formations of Tellemarken. The relations of the latter formation to the primitive gneiss are not touched upon in Dahll's paper ; but in another ^' Om Kongs- bergs Erts District," by Kjerulf and Dahll, it is asserted that the gneiss and mica schist of Kongsberg, or as they are called, the Kongsberg slates, " are exactly the same as those which in a more unchanged condition, are spread over large areas in Tellemarken," but separated from these by a band of eruptive gneiss-granite. The primitive gneiss formation is declared to have no existence, but to be resolvable into gneiss-granite, which is eruptive, and into slates, whose two principal types are quartz slate and hornblende slate. It is even said that gneiss " as a petrographical term, in its older and more extended meaning, is no longer advantageous to science, but the opposite." The order of succession in these older group?, according to Kjerulf and Dahll, is as follows, com- mencing wilh the oldest: 1. Tellemarken slates. 2. Granite and gneiss-granite. (Eruptive.) 170 Macfarlane on the Primitive Formations 3. (Esterdal slates (which are the same as the DovreQeld slates.) 4. Silurian formation. 5. Devonian formation. 6. Younger granite, syenite, &c. (Eruptive.) That the extreme opinions entertained by Kjernlf and Dahll as to the gneiss formation, are capable of being substantiated, is much to be doubted. At least it seems to me that in their work above cited, nothing very conclusive is brought forward in support of their views, and moreover, no reference is made to the many well substantiated facts, upon which the older view, as to the age of the Tellemarken quartzose rocks, is founded. This total oblitera- tion of the gneiss formation, is perhaps the most extreme point to which the supporters of ultra metamorphism have yet at- tained. The views of the Canadian geologists as to the Laurentian and Huronian series are the same as those of the older geologists of Norway, where, as has been shown, these rocks are represented by the Primitive Gneiss, and by the quartzose division of the Pri- mitive Slate formation. The DovreQeld slates, with their serpen- tines, are regarded as more recent, and as closely related to the adjacent Silurian strata. This is precisely the view of the Canadian geologists, with regard to the Quebec group, except that they include this, with its slates and serpentines, in the Silu- rian series, regarding it as a peculiar development of the lower part of this, and younger than the Primordial Zone. According to Sir W. E. Logan, this Quebec group was connected with a deep sea, and with movements of elevation and subsidence, the result of which is, that along the outcrop, or the shore line of the original basin, these peculiar strata are wanting. Mr. Sterry Hunt has called attention in a recent paper in this Journal, to the fact that a similar condition of things to that of Canada, seems traceable across the ocean, into Scotland, and probably as far as Scandinavia. In the Scottish Highlands, we find a schistose series, having the lithological characters of the Quebec group and the Dovrefjeld slates. This series has been the subject of much controversy. As in Norway, some have maintained that these strata are older than the lowest Silurian rocks, but Sir Roderick Murchison, with Ramsay and Harkness, seems to have shown that they are really younger than the oldest fossiliferous rocks of Scotland, and that the condi- tion of things described by the Canadian geologists in Eastern Canada, extends across the Atlantic. Can. Nat. Vol. VI, 93. in Norway and in Canada, 171 Thus is it not only in Canada, that the position of the rocks of the schistose group is equivocal. Different views prevail as to their age in different countries. In Cornwall, they are considered Devonian, in Scotland, Lower Silurian, and in Bohemia, as in Nor- way, Pre-Silurian. In Belgium, Rhenish Prussia, Westphalia and Nassau, they are by some geologists regarded as Devonian, and by others as belonging to an older formation. In East Russia, on the western slope of the Ural Mountains, they are supposed to represent metamorphic Lower Silurian strata. A dissimilarity of views will probably continue to prevail as to the position of these rocks, until the question is decided, as to what value, in the absence of fossil remains, the petrographical characters of a group, taken in connection with its stratigraphical position, should have in determining its age. Perhaps there prevails at present, too much of a tendency to attribute extraordinary influences to metamorphic agencies. So soon as the true limits and effects of metamorphism are recognized, it will probably be acknowledged that, whatever view may be entertained as to their origin, the schistose rocks above referred to, underlie the Silurian, and all unaltered or metamorphosed fossiliferous strata. Follow- ing close upon more moderate views as to metamorphism, will probably come the recognition of Werner's old rule, as to the suc- cession of these older rocks ; namely that the gneiss groups gene- rally underlie those in which mica schist preponderates, and that the latter are overlaid by argillaceous and cbloritic groups. Thus the ground will be cleared for an impartial investigation into the origin ot the primitive formations. Acton Vale, Canada East, 8th April, 1862.

Dorsal aspect. Dull olive green, darker on the head ; prima- ries and secondaries brown, the latter edged with brownish-white; orbit surrounded by a ring of the same colour. Tail square, of same colour as the wings, with a minute edging of white on the outer vane of the lateral feathers. Ventral aspect. Pale yellowish-white verging to an olive brown on the sides of the breast ; inner wing and tail coverts pale yel- low. 3rd primary longest ; 2nd subequal to 4th ; and 1st to the 6th.

Bill depressed, with nuchal bristles ; both man- dibles of equal length and acute, upper one scarcely notched, scarcely bent at tip, and scarcely inflected on the lower ; 2nd and 3rd primaries subequal ; tail long and subcuneiform. The birds of this genus are included under the sub gen. Saxicola of Genus Motacilla of Cuvier. They appear, however, to deserve a separate generic position by themselves, being intermediate between the Muscipetal and Sylvian tribes, possessing the depressed inflected bill of the fc^mer, and the long tail and tarsi of the latter, being . more musical than the former, in fact emulating the latter in point of vocal capacity. S. ruticilla. American Redstart. Muscicapa ruticilla^ of Linngeus and Wilson !! Ruticilla minor Americana of Edwards ! Setophagus ruticilla. Baird ! v.s.p. Bill, tarsi, claws and irides black ; eggs 3 to 4, cream white mottled with yellowish-brown. Dorsal aspect. Crown of head, nape of neck, dorsal region, rump and scapulars deep black; tail of 12 feathers, long, round, four centre ones black, the others orange, with thin distal halves black; primaries and secondaries, except the outer web of the 1st, and the three or four last secondaries orange at their insertion, and the remainder black, the orange gradually increasing in breadth and depth of tint as far as the secondaries.

Length about 5 inches ; alar breadth about Y inches. The female has the tints paler, and the orange changes to a yellow. The young birds thus far resemble the female, but in exception they are deficient in the orange tint of the wings, and are paler in other respects. S. Buonapartii. Buonaparte's Gnat-catcher. v.s.p. Upper mandible blackish-brown; lower one pale at base edged with blackish brown; tarsi, toes and nails pale; eggs unknown. Dorsal aspect. Greyish-ash except the crown, the feathers of which are black minutely tipped with grey, and the interscapular space which is faintly olive green. A yellow streak from the nostrils invests the eye, and a black streak from the angle of the mouth proceeds below the eye to the shoulders, where it appears to commence the zone of black spots which cross the chest like a necklace ; auriculars grey ; primaries and secondaries with the tail pale brown. The two former paler on the inner vanes and edged with white towards the quills. Ventral aspect. Bright gamboge yellow, only interrupted by a zone of black spots across the chest. These spots are caused by the feathers in that place being tipped with black. Tail and wing coverts whitish. 3rd primary longest ; 2nd and 4th subequal ; 1st shorter than the 4tb, but longer than 5th. Length 4| inches ; alar expanse 8 inches. This bird is rarely met with. The specimen from which the foregoing description is taken, was killed at St. Kemi in the spring of 1858. Is their sufficient difference between this bird and the Sylvia pardalina, to constitute two species of different genera ? Genus Vireo. Gen. char. Bill short, moderately compressed, curved at the base, with nuchal bristles ; upper mandible curved at the extrem- ity, slightly notched, resembling in this respect the Muscipeta, but differing from the latter in being more compressed, and not at all depressed, in consequence of which it is deeper than broad ; lower mandible a little shorter than the upper, and recurved slightly at of the District of MontreaL 177 the tip ; tongue cartilaginous and bifid ; 2nd and 3rd piimaries longest ; outer toes connected at the base.

On the Island of Montreal it is not plentiful, but is found much more numerous- ly in the groves of St. Remi on the south side of the river. S. virens. Black-throated Green Warbler. Dendroica virens.

Nat. 13 Vol. VII 194 Macfarlane on the Extraction of Cobalt Oxide ARTICLE XVIIL— O/z the Extraction of Cobalt Oxide from the Iron Pyrites occurring near Brockville, C. W, By Thomas Macfarlane. About two miles to the north-west of Brockville, in the town- ship of Elizabethtown, C. W., there exists a deposit of iron pyrites ofvery considerable extent and importance. It belongs to the Lau- rentian system, but it is not known what rocks immediately ad- join it, as they do not come to the surface. Although an exca- vation of fifty feet long, and thirty broad, has been made in the deposit, the limit of the minerals in either direction, has not been reached. Two varieties of the pyrites are found here, the one somewhat porous and dull, and the other compact, of a yellow- ish-white colour, and a very bright lustre. Iron pyrites, as is well known, contains one equivalent of iron and two of sulphur ; or 45. YY per cent, of the former, and 54.23 per cent, of the lat- ter element. It is a most important source of sulphur for the manufacture of sulphuric acid. The iron pyrites of the above mentioned locality contains the usual constituents, but in the com- pact variety especially, a portion of the iron is replaced by a small per centage of cobalt, equal, according to Dr. Hunt's anal- ysis, to 0.52 per cent, of cobalt oxide, and according to my own to 0.50 per cent. The occurrence of cobalt in many pyrites of the Laurentian formation, has been repeatedly remarked by Dr. Hunt, and I have detected its presence in many specimens of pyrites occurring in the Primitive Gneiss formation in Norway. While at the Modum Smalt works, and the Skuterud cobalt mines in that country, I had opportunities of experimenting on these pyrites, and of devising a process for economically extract- ing the cobalt which they contain. The principal object of the present paper is to describe the manner in which this process might be advantageously applied in treating the Brockville py- rites. When the compact variety of the cobaltiferous iron pyrites of the above deposit, in fine powder, is mixed with one-tenth of its weight of common salt, also finely divided, and calcined at a low red heat, with free access of air, the following chemical changes take place : — First, the greater part of the sulphur of the pyrites is oxidized, and disengaged as sulphurous acid, the iron also combining with oxygen and forming peroxide of iron. At the same time the small proportion of cobalt present is con- from the Iron Pyrites occurring near BrocJcville. 195 verted into cobalt oxide. At a later stage of the operation, part of the sulphurous acid formed comes in contact with the peroxide of iron, and is, through its agency, further oxidized into sulphuric acid, which combines with the iron oxide, forming finally a com- paratively small quantity of sulphate of peroxide of iron. The cobalt oxide also combines with sulphuric acid, forming sulphate of protoxide of cobalt. These sulphates react on the common salt, producing sulphate of soda, with perchloride of iron and protochloride of cobalt. Air having still access, the perchloride of iron is resolved into peroxide of iron and chlorine gas, which es- capes and may be recognized by its odour, so soon as the evolu- tion of sulphurous acid has ceased. Protochloride of cobalt is also decomposable by heating in a current of air, the products being chlorine and cobalt oxide ; but this change does not take place until the perchloride of iron has been wholly decomposed. It is at this point that the calcination must be interrupted; that is, as soon as the perchloride of iron is decomposed, but before the decomposition of the protochloride of cobalt commences. When the operation is stopped exactly at this point, the calcined resi- due yields with water a solution containing no iron oxide, or but a trace, and the whole of the cobalt in the state of protochloride. I have made many trials of the above process with the Brock" ville pyrites, all yielding results confirmatory of the above reac- tions. Tho following are among the most conclusive of them : 1000 grains of the ore were calcined as above described, with 100 grains of common salt in a common muffle furnace. The mate- rials were withdrawn from the muflfle, as soon as strong and pure chlorine commenced to be evolved, and the evolution of chlorine continued until the materials were cooled to a certain point. The calcined residue weighed 780 grains, and contained in 100 parts, Peroxide of iron 85.300. Sulphate of soda 5.700 = 1.28 sulphur. Protochloride of cobalt, . . 1.343 = 0.775 cobalt oxide. Protochloride of copper.. 0.327 = 0.193 cupric oxide. Perchloride of iron 0.059 = 0.029 ferric oxide. Chloride of sodium 7,271 by difference. 100.000 The five last mentioned constituents were of course soluble in water. According to these results, the 780 grains of residue must have contained six grains of cobalt oxide ; consequently 0.60 per cent, of this substance had been extracted from the pyrites. The 196 Macfarlane on the Extraction of Cobalt Oxide 1000 grains of pyrites contained 542.3 grains of sulphur, and the 780 grains of the residue, only 9.98 grains Consequently 98.16 per cent, of the sulphur had escaped as sulphurous acid, and only 1.84 per cent, had been converted into sulphuric acid and combined with soda. That the iron oxide, as stated above, has considerable influence in converting the sulphurous acid into sulphuric acid, will appear from the following experiment: 59 grains of iron pyrites, 58^ grains of common salt, and 234 grains peroxide of iron, (free from sulphuric acid) were mixed and calcined in a mufl3e, at a low red heat, until sulphurous acid and chlorine ceased to be evolved. The materials weighed after calcination 336 grains, and contained in 100 parts : Peroxide of iron 19.5 Sulphate of soda 19.2 = 4.31 sulphur. Chloride of sodium. ... 1.3 by difference. 100.0 The original 59 grains of iron pyrites used, contained 32, and the resulting 336 grains, 14.48 grains of sulphur. Conse- quently 55 per cent, of the sulphur had escaped as sulphurous acid,* and 45 per cent, were converted into sulphuric acid, instead of 1.84 per cent, as in the experiment above described. That the larger quantity of salt used did not materially contribute to this result, I have proved by a series of experiments, which resulted as follows : — 1. When iron pyrites, mixed with 5 per cent, of its weight of common salt, is calcined as in the last described experiment, 1.24 per cent, of the sulphur contained in it, is converted into sulphuric acid, and combined with the soda. 2. When 10 per cent, of salt is used, 1.84 per cent, of the sul- phur is, as we have seen, converted into sulphuric acid. 3. With 50 per cent, of salt, 2.86 per cent, of the sulphur is re- tained as sulphuric acid. 4. With 100 per cent, of salt, 7.46 of the sulphur is thus re- tained. In this last, thry furnace, heated to low redness, raked about, and tested from time to time. So soon as pure chlorine is evolved, and the mass ceases to glow in the furnace, and gives with water a solution containing little or no iron, the mixture is withdrawn from the furnace. When cool, it is brought into a large tub, where it is stirred up with hot water. If the calcination has been properly performed, a solution is obtained having a beautiful rose colour. This is drawn off, or if necessary filtered from the insoluble residue of peroxide of iron which is washed with fresh quantities of water until it no longer yields a solution containing cobalt The more dilute solutions thus obtained, are used for treating fresh quantities of the cal- oined material. The rose-coloured solution contains besides the oobalt, a small quantity of copper, and a trace of iron, together with whatever sulphate of soda has been formed, and the com- mon salt which may have been left undecomj^osed. The copper and iron may be separated from the solution by adding a slight quantity of a dilute solution of carbonate cf soda. They are pre- cipitated as carbonates, before the cobalt, and are separated from the solution by filtration. The filtrate is then treated with a further quantity of a solution of carbonate of soda, more con- • Fabriques de produits chimiques.

Carbonate of oxide of cobalt falls as a peach-blossom colored precipitate. This is washed by subsidence and decantation, collected on a linen filter, dried and ignited in close vessels. The result is pure cobalt oxide, such as is used for imparting a blue colour to porcelain and stone-ware. Its price in the English market, about a year ago, was thirteen shillings sterling the pound, and probably its present value may with safety be assumed to be eleven shillings sterling. The cost of the process above described, depends of course,, much on the locality where it is carried into operation. But even supposing this to be some distance from the mine, I believe the manufacture would be found to be remunerative. The cost of both mining and manufacturing might be estimated as follows : — Excavation, per ton $3 .00 Roasting " 0.25 Freight to factory, say 2.50 Stamping 0.50 Calcining 6.00 Lixiviatiou, precipitation, &c 1.25 Freight to market, agency, &c 0.50 $14.00 From one ton of ore there might be produced, making some allowance for occasional failures, at least eight pounds of cobalt oxide, worth eleven shillings sterling the pound, equal to £4 8 0 Or $21.12. I think therefore that the treatment of the Brockville pyrites for cobalt might reasonably be expected to yield a profit of, say $7 per ton. Of course, many disadvantages and failures are apt to attend the commencement of any new manufacture, but in the above estimate I have made some allow- ance for such. In this calculation, I have reckoned nothing for the sulphur which the pyrites contains. Were the manufacture of sulphuric acid combined with that of the cobalt oxide, there is no doubt but that a very remunerative business might be established. Canada is certainly not a manufacturing country. It is therefore improbable that much sulphuric acid would be used here for manufacturing soda, or in bleaching or dyeing. But Canada contains inexhaustible sources of rock oil or petroleum. Ow- ing to the ofi"ensive odour of this substance in its crude state, it is diflScult to prooure freight for it to Great Britain. This neces- from the Iron Pyrites occurring near BrocJcville, 199 sitates its purification in Canada, and as is well known, sulphuric acid is the most efi'ective deodorizer that can be employed in re- fining it. In proportion then as refineries for petroleum are es- tablished, the demand for sulphuric acid will increase, and no doubt a manufactory of this acid would be able to dispose of an immense quantity. There are very few chemical manufactures which may be said to be indigenous to Canada, but this one, of the products to be obtained from these pyrites, in conjunction with that of refined oils from crude petroleum, possessing a natural and sound foundation in the province, would flourish rapidly, and doubtless be permanently successful.

The following list of those engaged in the study of Entomology in Canada has been prepared chiefly with the object of making collectors known to each other. It is almost unnecessary to state that the idea was suggested by the lists in Stainton's Entomologists' Annuals. It was at first considered that the great and primary ad- vantage to be derived from it was that collectors in one part of the country would be enabled by its means to find out who are addicted to their favourite pursuit in other places, and thus obtain specimens of those local species in which their own collections are deficient Since, however, the number of those engaged in this study has proved to be so much larger than was at first anticipa- ted, several of my correspondents have agreed with me in the opin- ion that it would tend very much to the advancement of Entomo- logy in this country, were a club to be formed, and meetings to be held once or twice a year at some central place, to be decided upon hereafter. We have come to the conclusion that, if this project meets with sufficient encouragement from Entomologists, no better time or place could be selected for the first meeting than that appointed for the next exhibition of the Provincial Agricultu- ral Association, which is to be held at Toronto, during the week commencing September 22nd, 1862. If such a meeting can be held, it is much to be desired that Entomologists should bring to it all their undetermined specimens, as well as any duplicates they may have of rare species; by so doing favours could be mutually conferred, and much information difl'used with regard to the dis- tribution of species, etc. The Meeting would, doubtless, prove ad- ^0 Rev. Chas. J. S. Bethune vantageous in many other respects ; and, in addition, such a reu- nion of kindred spirits could not fail to prove exceedingly agree- able. I trust, therefore, that this project may not fall to the ground, but that before long, Canadian Entoniologists may have the pleasure of making each other's acquaintance. In the following list is enumerated every Entomologist in Ca- nada whose name and address I could learn, and who was willing to permit his name to appear ; there may be a few others, — if so I trust they will speedily make themselves known either to Mr. Saunders (who has kindly shared with me the trouble of prepar- ing this list) or to myself. 1.

ARTICLE XXn.— ^ Lecture on Force, delivered before the Royal Institution of Great Britain on the 'fith of June, 1862, hy Prof. John Tyndal, F.R.S.* The existence of the International Exhibition suggested to our Honorary Secretary the idea of demoting the Friday evenings after Easter of the present year to discourses on the various agen- cies on which the material strength of England is based. He wished to make iron, coal, cotton, and kindred matters, the sub- jects of these discourses ; opening the series by a discourse on the Great Exhibition itself ; and he wished me to finish the series by a discourse on Force in general. For some months I thought over the subject at intervals, and had devised a plan of dealing with it ; but three weeks ago I was induced to swerve from this plan for reasons which shall be made known towards the conclu- sion of the discourse. We all have ideas more or less distinct regarding force ; we know in a general way what muscular force means, and each of us would less willingly accept a blow from a pugilist than have his ears boxed by a lady. But these general ideas are not now sufficient for us ; we must learn how to express numerically the exact mechanical value of the two blows ; this is the first point to be cleared up. * From the L. E. and D. Philosophical Magazine for July, 1862. Can. Nat. 16 Vol. 711 242 Professor TyndaVs Lecture on Force, [A sphere of lead weighing one pound was suspended at a height 16 feet above the theatre floor. It was liberated, and fell by- gravity. The weight required exactly a second to fall to the earth from that elevation ; and the instant before it touched the earth, it had a velocity of 32 feet a second. That is to say, if at that instant the earth were annihilated, and its attraction an- nulled, the weight would proceed through space at the uniform velocity of 32 feet a second.] Suppose that instead of being pulled down by gravity, the weight is cast upward in opposition to the force of gravity, with what velocity must it start from the earth's surface in order to reach a height of 16 feet ? "With a velocity of 32 feet a second. This velocity imparted to the weight by the human arm, or by any other mechanical means, would carry the weight up to the precise height from which it had fallen. Now, the lifting of the weight may be regarded as so much mechanical wort. I might place a ladder against a wall, and carry the weight up a height of 16 feet; or I might draw it up to this height by means of a string and pulley, or I might sud- denly jerk it up to a height of 16 feet. The amount of work done in all these cases, as far as the raising of the weight is con- cerned, would be absolutely the same. The absolute amount of work done depends solely upon two things : first of all, on the quantity of matter that is lifted ; and secondly, on the height to which it is lifted. If you call the quantity or mass of matter m, and the height through which it is lifted A, then the product of m into ^, or mh, expresses the amount of work done. Supposing, now, that instead of imparting a velocity of 32 feet a second to the weight, we impart twice this speed, or 64 feet a second. To what height will the weight rise ! You might be- disposed to answer, "To twice the height:" but this would be quite incorrect. Both theory and experiment inform us that the weight would rise to four times the height ; instead of twice 16^ or 32 feet, it would reach four times 16, or 64 feet. So also, if we treble the starting velocity, the weight would reach nine times the height; if we quadruple the speed at starting, we attain six- teen times the height. Thus, with a velocity of 128 feet a second at starting, the weight would attain an elevation of 256 feet. Supposing we augment the velocity of starting seven times, we should raise the weight to 49 times the height, or to an elevation of 784 feet. Professor TyndaVs Lecture on Force. 243 Now the work done — or, as it is sometimes called the mechan- ical effect — as before explained, is proportional to the height, and as a double velocity gives four times the height, a treble velocity nine times the height, and so on, it is perfectly plain that the mechanical eflfect increases as the square of the velocity. If the mass of the body be represented by the letter m, and its velocity by V, then the mechanical eflfect would be represented by wv^. In the case considered, I have supposed the weight to be cast upward, being opposed in its upward flight by the resistance of gravity ; but the same holds true if I send the projectile into water, mud, earth, timber, or other resisting material. If, for example, you double the velocity of a cannon-ball, you quadruple its mechanical eflfect. Hence the importance of augmentine the velocity of a projectile, and hence the philosophy of Sir William Armstrong in using a 50 pound charge of powder in his recent striking experiments. The measure then of mechanical eflfect is the mass of the body multiplied by the square of its velocity. Now, in firing a ball against a target, the projectile, after col- lision, is often found hissing hot. Mr. Fairbairn informs me that in the experiments at Shoeburyness it is a common thino- to see a flash of light, even in broad day, when the ball strikes the tar- get. And if I examine my lead weight after it has fallen from a height, I also find it heated. Now, here experiment and reason- ing lead us to the remarkable law that the amount of heat gen- erated, like the mechanical eflfect, is proportional to the product of the mass into the square of the velocity. Double your mass, other things being equal, and you double your amount of heat ; double your velocity, other things remaining equal, and you qua- druple your amount of heat. Here then we have common me- chanical motion destroyed and heat produced. I take this Wolin bow and draw it across this string. You hear the sound. That sound is due to motion imparted to the air, and to produce that motion a certain portion of the muscular force of my arm must be expended. ^Ye may here correctly say, that the mechanical force of my arm is converted into music. And in a similar way we say that the impeded motion of our descending weight, or of the arrested cannon-ball is converted into heat. The mode of motion changes, but it still continues motion ; the motion of the mass is converted into a motion of the atoms of the mass ; and these small motions communicated to the nerves, produce the 244 Professor TyndaVs Lecture on Force, sensation which we call heat. We, moreover, know the amount of heat which a given amount of mechanical force can develope. Our lead ball, for example, in falling to the earth generated a quantity of heat sufficient to raise the temperature of its own mass three-fifths of a Fahrenheit degree. It reached the earth with a velocity of thirty-two feet a second, and forty times this velocity would be a small one for a rifle bullet. Multiplying three-fifths by the square of forty we find that the amount of heat developed by collision with the target would, if wholly concentrated in the lead, raise its temperature 960 degrees. This would be more than suf- ficient to fuse the lead. In reality, however, the heat developed is divided between the lead and the body against which it strikes ; nevertheless, it would be worth while to pay attention to this .point, and to ascertain whether rifle bullets do not, under some circumstances, show signs of fusion. From the motion of sensible masses, by gravity and other means, the speaker passed to the motion of atoms towards each other by chemical affinity. A collodion balloon, filled with a mixture of chlorine and hydrogen, was hung in the focus of a parabolic mirror, and in the focus of a second mirror, twenty feet distant, ^ strong electric light was suddenly generated. The instant the light fell upon the balloon the atoms within it fell together with explosion, and hydrochloric acid was the result. The burning of charcoal in oxygen is an old experiment, but it has now a significance beyond what it used to have ; we now regard the act of combination on the part of the atoms of oxygen and coal, ex- actly as we regard the clashing of a falling weight against the earth. And the heat produced in both cases is referable to a common cause. This glowing diamond, which burns in oxygen as a star of white light, glows and burns in consequence of the fallincr of the atoms of oxygen against it. And could we mea- sure the velocity of the atoms when they clash, and could we find their number and weight, multiplying the mass of each atom by the square of its velocity, and adding all together, we should get a number representing the exact amount of heat developed by the union of the oxygen and carbon. Thus far we have regarded the heat developed by the clashing ^f sensible masses and of atoms. Work is expended in giving motion to these atoms or masses, and heat is developed. But we reverse this process daily, and by the expenditure of heat execute work. We can raise a weight by heat ; and in this agent we Professor TyndaPs Lecture on Force. 245- possess an enormous store of mechanical power. This pound of coal, which I hold in my hand, produces by its combination with oxygen an amount of heat, which, if mechanically applied, would suflBce to raise a weight of one hundred lbs. to a height of twenty miles above the earth's surface. Conversely, one hundred pounds falling from a height of twenty miles, and striking against the earth, would generate an amount of heat equal to that developed by the combustion of a pound of coal. Wherever work is done by heat, heat disappears. A gun which fires a ball is less heated than one which fires blank cartridge. The quantity of heat com- municated to th^ boiler of a working steam-engine is greater than which could be obtained from the re-condensation of the steam after it had done its work ; and the amount of work performed is the exact equivalent of the amount of heat lost. Mr. Smyth informed us in his interesting discourse, that we dig annually 84 millions of tons of coal from our pits. The amount of mechanical force represented by this quantity of coal seems perfectly fabu- lous. The combustion of a single pound of coal, supposing it to take place in a minute, would be equivalent to the work of 300 horses; and if we suppose 108 millions of horses working day" and night, with unimpaired strength, for a year, their united energies would enable them to perform an amount of work just equivalent to that which the annual produce of our coal-fields would be able to accomplish. Comparing with ordinary gravity the energy of the force with which oxygen and carbon unite together, the chemical aflBnity^ seems almost infinite. But let us give gravity fair play : let us permit it to act throughout its entire range. Place a body at such a distance from the earth that the attraction of the earth is barely sensible, and let it fall to the earth from this distance. It would reach the earth with a final velocity of 36,747 feet in a second ; and on collision with the earth the body would gener- ate about twice the amount of heat generated by the combustion of an equal weight of coal. We have stated that by falling through a space of sixteen feet, our lead bullet would be heated three-fifths of a degree ; but a body falling from an infinite dis- tance has already used up 1,299,999 parts out of 1,300,000 of the earth's pulling power, when it has arrived within IG feet of the surface; in this space only Taooooo^^'s of the whole force is exerted. Let us now turn our thoughts for a moment from the earth to- 246 Professor TyndaVs Lecture on Force. wards the sun. The researches of Sir John Herschel and Mr Pouillet have informed us of the annual expenditure of the sun as regards heat ; and by an easy calculation we ascertain the precise amount of the expenditure which falls to the share of our planet. Out of 2300 million parts of light and heat the earth receives one. The whole heat emitted by the sun in a minute would be competent to boil 12,000 millions of cubic miles of ice- cold water. How is this enormous loss made good ? Whence is the sun's heat derived, and by what means is it maintained ? No combustion, no chemical affinity with which we are acquainted would be competent to produce the temperature of the sun's sur- face. Besides, were the sun a burning body merely, its light and heat would assuredly speedily come to an end. Supposing it to be a solid globe of coal, its combustion would only cover 4600 years of expenditure. In this short time it would burn it- self out. What agency can then produce the temperature and maintain the outlay ? We have already regarded the case of a body falling from a great distance towards the earth, and found that the heat generated by its collision would be twice that pro- duced by the combustion of an equal weight of coal. How much greater must be the heat developed by a body falling towards the sun ! The maximum velocity with which a body can strike the earth is about seven miles in a second ; the maximum velocity with which it can strike the sun is 390 miles in a second. And as the heat developed by the collision is proportional to the square of the velocity destroyed, an asteroid falling into the sun with the above velocity, would generate about 10,000 times the quantity of heat generated by the combustion of an asteroid of coal of the same weight. Have we any reason to believe that such bodies exist in space, and that they may be raining down upon the sun ? The meteorites flashing through the air are small planetary bodies, drawn by the earth's attraction, and entering our atmosphere with planetary velocity. By friction against the air they are raised to incandescence, and caused to emit light and heat. At certain seasons of the year they shower down upon us in great numbers. In Boston 240,000 of them were observed in nine hours. There is no reason to suppose that the planetary system is limited to " vast masses of enormous weight ;" there is every reason to believe that space is stocked with smaller masses, which obey the same laws as the large ones. That lenticular en- velope which surrounds the sun, and which is known to astron- Professor TyndaVs Lecture on Force. 247 omers as the zodiacal light, is probably a cloud of meteors ; and moving, as they do, in a resisting medium they must continually approach the sun. Falling into it, they would be competent to produce the heat observed, and this would constitute a source from which the annual loss of heat would be made good. The sun, according to this hypothesis, would be continually growing larger ; but how much larger ? Were our moon to fall into the sun it would deveiope an amount of heat sufficient to cover one or two years' loss ; and were our earth to fall into the sun a cen- tury's loss would be made good. Still, our moon and our earth, if distributed over the surface of the sun, would utterly vanish from perception. Indeed, the quantity of matter competent to produce the necessary effect would, during the rang« of history, produce no appreciable augmentation in the sun's magnitude. The augmentation of the sun's attractive force would be more appreciable. However this hypothesis may fare as a represen- tant of what is going on in nature, it certainly shows how a sun might be formed and maintained by the application of known thermo-dynamic principles. Our earth moves in its orbit with a velocity of 68,040 miles an hour. Were this motion stopped, an amount of heat would be developed sufficient to raise the temperature of a globe of lead of the same size as the earth, 384,000*^ of the centigrade ther- mometer. It has been prophesied that " the elements shall melt with fervent heat." The earth's own motion embraces the con- ditions of fulfilment ; stop that motion, and the greater part, if not the whole of her mass, would be reduced to vapour. If the earth fell into the sun, the amount of heat developed by the shock would be equal to that developed by the combustion of 6435 earths of solid coal. There is one other consideration connected with the perma- nence of our present terrestrial conditions, which is well worthy of our attention. Standing upon one of the London bridges, we observe the current of the Thames reversed, and the water poured upward twice a-day. The water thus moved, rubs against the river's bed and sides, and heat is the consequence of this friction. The heat thus generated is in part radiated into space, and then lost, as far as the earth is concerned. What is it that supplies this incessant loss ? The earth's rotation. Let us look a little more closely at the matter. Imagine the moon fixed, and the earth turning like a wheel from west to east in its diurnal rota- 248 Professor TyndaVs Lecture on Force. tion. Suppose a higli mountain on the earth's surface ; on ap- proaching the moon's meridian, that mountain is, as it were, laid hold of by the moon, and forms a kind of handle by which the earth is pulled more quickly round. But when the meridian is passed, the pull of the moon on the mountain would be in the opposite direction, it now tends to diminish the velocity of rota- tion as much as it previously augmented it ; and thus the action of all fixed bodies on the earth's surface is neutralized. But sup- pose the mountain to lie always to the east of the moon's meridian, the pull then would be always exerted against the earth's rota- tion, the velocity of which would be diminished in a degree cor- responding to the strength of the pull. The tidal wave occupies this position — it lies always to the east of the moon's meridian, and thus the waters of the ocean are in part dragged as a brake along the surface of the earth ; and as a brake they must dimin- ish the velocity of the earth's rotation. The diminution, though inevitable, is, however, too small to make itself felt within the period over which observations on the subject extend. Supposing, then, that we turn a mill by the action of the tide, and produce heat by the friction of the millstones ; that heat has an origin totally diflferent from the heat produced by another mill which is turned by a mountain stream. The former is produced at the expense of the earth's rotation ; the latter at the expense of the sun's radiation. The sun, by the act of vaporisation, lifts mechanically all the moisture of our air. It condenses and falls in the form of rain, — it freezes and falls as snow. In this solid form it is piled upon the Alpine heights, and furnishes materials for the glaciers of the Alps, But the sun again interposes, liberates the solidified liquid, and permits it to roll by gravity to the sea. The mechanical force of every river in the world, as it rolls towards the ocean, is drawn from the heat of the sun. No streamlet glides to a lower level without having been first lifted to the elevation from which it springs, by the mighty power of the sun. The energy of winds is also due entirely to the sun ; but there is still another work which he performs, and his connection with which is not so ob- vious. Trees and vegetables grow upon the earth, and when burned they give rise to heat, and hence to mechanical energy. Whence is this power derived ? You see this oxyd of iron, pro- duced by the falling together of the atoms of iron and oxygen;, here also is a transparent gas which you cannot now see — car- Professor TyndaVs Lecture on Force. 249- bonic acid gas — which is formed by the falling together of carbon and oxygen. These atoms thus in close union resemble our lead weight while resting on the earth ; but I can wind up the weight and prepare it for another fall, and so these atoms can be wound up, separated from each other, and thus enabled to repeat the process of combination. In the building of plants carbonic acid is the material from which the carbon of the plant is derived; and the solar beam is the agent which tears the atoms asunder, setting the oxygen free, and allowing the carbon to aggregate in woody fibre. Let the solar rays fall upon a surface of sand ; the sand is heated, and finally radiates away as much heat as it receives ; let the same beams fall upon a forest, the quantity of heat given back is less than the forest receives, for the energy of a portion of the sunbeams is invested in building up the trees, in the man- ner indicated. "Without the sun the reduction of the carbonic acid cannot be eff'ected, and an amount of sunlight is consumed exactly equivalent to the molecular work done. Thus trees are formed; thus the cotton, on which Mr. Bazley discoursed last Friday, is formed. I ignite this cotton, and it flames ; the oxygen again unites with its beloved carbon; but an amount of heat equal to that which you see produced by its combustion was sa- crificed by the sun to form that bit of cotton. But we cannot stop at vegetable hfe, for this is the source, mediate or immediate, of all animal life. The sun severs the carbon from its oxygen ; the animal consumes the vegetable thus formed, and in its arteries a reunion of the severed elements takes place, and produces animal heat. Thus, strictly speaking, the process of building a vegetable is one of winding up ; the pro^ cess of building an animal is one of running down. The warmth of our bodies, and every mechanical energy which we exert, trace their lineage directly to the sun. The fight of a pair of pugilists, the motion of an army, or the lifting of his own body up moun- tain slopes by an Alpine climber, are all cases of mechanical en- ergy drawn from the sun. Not, therefore, in a poetical, but in a purely mechanical sense, are we children of the sun. Without food we should soon oxidise our own bodies. A man weighing 150 lbs. has sixty-four lbs. of muscle; but these, when dried, reduce themselves to fifteen lbs. During an ordinary day's work, for eighty days, this mass of muscle would be wholly oxidised. Special organs which do more work would be more quickly oxi- dised : the heart, for example, if entirely unsustained, would be 250 Professor Ty^idaVs Lecture on Force. oxidised in about a week. Take the amount of beat due to the direct oxidation of a given amount of food ; a less amount of heat is developed by this food in the working animal frame, and the missing quantity is the exact equivalent of the mechanical work which the body accomplishes. I might extend these considerations ; the work, indeed, is done to my hand — but I am warned that I have kept you already too long. To whom, then, are we indebted for the striking general- isations of this evening's discourse ? All that I have laid before you is the work of a man of whom you have scarcely ever heard. All that I have brought before you has been taken from the la- bors of a German physician, named Mayer. Without external stimulus, and pursuing his profession as town physician in Heil- bronn, this man was the first to raise the conception of the in- teraction of natural forces to clearness in his own mind. And yet he is scarcely ever heard of in scientific lectures, and even to scientific men his merits are but partially known. Led by his own beautiful researches, and quite independent of Mayer, Mr. Joule published his first paper on the "Mechanical Value of Heat," in 1843 ; but in 1842 Mayer had actually calculated the mechanical equivalent of heat from data which a man of rare originality alone could turn to account. From the velocity of sound in air Mayer determined the mechanical equivalent of heat. In 1845 he published his Memoir on " Organic Motion," and ap- plied the mechanical theory of heat in the most fearless and pre- cise manner to vital processes. He also embraced the other natural agents in his chain of conservation. In 1853 Mr. Wa- terston proposed, independently, the meteoric theory of the sun's heat, and in 1854, Professor William Thomson applied his ad- mirable mathematical powers to the development of the theory ; but six years previously, the subject had been handled in a mas- terly manner by Mayer, and all that I have said on this subject has been derived from him. When we consider the circum- stances of Mayer's life, and the period at which he wrote, we cannot fail to be struck with astonishment at what he has accom- plished. Here was a man of genius working in silence, animated solely by a love of his subject, and arriving at the most impor- tant results, some time in advance of those whose lives were en- tirely devoted to Natural Philosophy. It was the accident of bleeding a feverish patient at Java in 1840, that led Mayer to speculate on these subjects. He noticed that the venous blood Professor TyndaVs Lectiire oji Force. 2-51 in the tropics was of a much brighter red than in colder latitudes, and his reasoning on this fact led him into the laboratory of natu- ral forces, -where he has worked with such signal ability and suc- cess. Well, you will desire to know what has become of this man. His mind gave way ; he became insane, and he was sent to a lunatic asylum. In a biographical dictionary of his country it is stated that he died there ; but this is incorrect. He recovered ; and, I believe, is at this moment a cultivator of vineyards in Heilbronn. While preparing for publication my last course of lectures on Heat, I wished to make myself acquainted with all that Mayer had done in connection with this subject. I accordingly wrote to two gentlemen who above all others seemed likely to give me the information which I needed. Both of them are Germans, and both particularly distinguished in connection with the Dynamical Theory of Heat. Each of them kindly furnished me with the list of Mayer's publications, and one of them was so friendly as to order them from a bookseller, and to send them to me. This friend, in his reply to my first letter regarding Mayer, stated his belief that I should not find anything very important in Mayer's writings; but before forwarding the memoirs to me he read them himself. His letter accompanying the first of these papers, contains the following words : — " I must here retract the statement in my last letter, that you would not find much matter of importance in Mayer's wiitings : I am astonished at the mul- titude of beautiful and correct thoughts which they contain ;" and he goes on to point out various important subjects, in the treatment of which Mayer had anticipated other eminent writers. My second friend, in whose own publications the name of Mayer repeatedly occurs, and whose papers containing these references were translated some years ago by myself, was, on the 10th of last month, unacquainted with the thoughtful and beautiful essay of Mayer's, entitled *' Beitrage zur Dynaraik des Himmels ;" and in 1854, when Professor William Thomson developed in so striking a manner the meteoric theory of the sun's heat, he was certainly not aware of the existence of that essay, though from a recent number in Mo.cmillan^s Magazine I infer that he is now aware of it. Mayer's physiological writings have been referred to by physiologists — by Dr. Carpenter, for example — in terms of honourable recognition. We have hitherto, indeed, obtained fragmentary glimpses of the man, partly from physicists and partly 252 Utilisation of the Power involved from physiologists ; but his total merit has never yet been recog- nised as it assuredly would have been had he chosen a happier mode of publication. I do not think a greater disservice could be done to a man of science, than to overstate his claims ; such overstatement is sure to recoil to the disadvantage of him in whose interest it is made. But when Mayer's opportunities,, achievements, and fate are taken into account, I do not think that I shall be deeply blamed for attempting to place him in that honourable position which I believe to be his due. Here, however, are the titles of Mayer's papers, the perusal of which will correct any error of judgment into which I may have fallen regarding their author.

ARTICLE XXIII. — On the Utilisation of the Power involved in the Pise and Pall of the tides.* The tendency of modern scientific discovery has been to show that all the various forms of force with which we are acquainted are mutually convertible into one another. Thus, of the six forces known to us in connection with the universe — gravitation, motion, light, heat, electricity, and chemical afiinity— it is well known that any one of the five latter is capable, by appropriate means, of generating the other four, the force of gravitation being ca- pable, through the medium of motion, of giving rise to the other five forces, whilst it cannot itself be generated. Gravitation may therefore be assumed to be the elemental force, since it is the only one of the six which will generate all the others. So accurately have these correlations been studied, that the quantitative value of gravitation has even been ascertained, it having been found that the mechanical force required to lift 772 pounds to the height of one foot, is capable, when converted into the force of heat, of raising the temperature of one pound of water 1°F. In other words, this amount of heat may be generated by an appropriate utilisation of the gravitating pull, exerted by a weight of 772 pounds during its downward movement through the space of one *From the " Chemical News," 12th July, 1862. {?i the Rise and Fall of the tides. 253 foot. Supposing, therefore, we were in possession of an unlimited number of 7 7 2 -pound weights, and were to employ in the most judicious manner the force thus evolved in their downward pro- gress, we should have an unlimited reservoir of power which could be converted at will into light, heat, electricity, or chemi- cal affinity, and could be made to toil for human benefit without any corresponding expenditure of human labour so long as the weights continued their downward progress unarrested. If, how- ever, any good were to be gained by such a machine, it must be managed so that the motive force — gravitation — should always remain on the pull, and this is, and always will be, the obstacle to the attainment of perpetual motion ; the act of overcoming the force of gravity to re-raise the weights, requiring the expenditure of exactly the same amount of power as has been generated dur- ing their downward fall ; and so, before we can seriously discuss the feasibility of such a machine, we must find a perpetual flow of gravitating force always at hand, craving to be satisfied, and yet inexhaustible. In other words, we must construct a clock which will wind itself up when the weight has run down, without any expenditure of human power. Sitting by the sea-shore a few days since, we could not help noticing the large reservoir of mechanical power existing in the ocean. We do not refer to the noisy dash of the waves as they break upon the beach, but to the infinitely mightier, although silent and progressive, energy exerted in the gradual rise and fall of the tides. Compared with the stupendous power capable of being utilised for man's benefit, and present in the rise or fall of millions upon millions of tons of water through a space of ten or twenty feet four times a-day, all the steam, water, or wind power in the world, together with the united muscular force of every living being, human and animal, sink into utter insignifi- cance. We will try to form some idea of this power. Let us suppose that by the action of the tides the difi"erence of level of the surface of the ocean at a certain spot, is 21 feet between high and low water ; omitting for the present all consideration of the power of the subjacent liquid, what is the mechanical value of a space of 100 yards square of this water ? 100 yards square by 21 feet deep equals 70,000 cubic yards of water, which are lifted to a height of 21 feet, or to 1,470,000 cubic yards Hfted to a height of 1 foot. Now, since one cubic yard of water weighs about 1683 pounds, 1,470,000 cubic yards weighs 2,474,010,000 254 Naumann on Primitive Formations, pounds, which is lifted in six hours. This is equivalent to lifting- a weight of 412,335,000 foot-pounds in one hour 5 and since one horse-power is considered equivalent to raising 1,800,000 foot- pounds per hour, we have locked up in every 100 yards square of sea surface, a power equal to a 236 horse-power steam-engine,, acting, be it remembered, day and night to the end of time, re- quiring no supervision, and costing nothing, after the first outlay, but the wear and tear of machinery. By means of appropriate machinery connected with this tidal movement, any kind of work could be readily performed. Water could be hoisted, or air compressed to any desired extent, so as to accumulate power for future use, or for transport to distant stations. Light of surpassing splendor could be generated by means of magneto-electric machines : and with a very little exer- cise of ingenuity, every lighthouse on the coast could be illumin- ated with sun-like brilliancy, and with absolutely no expenditure of fuel ; the very same mechanical power of the ocean, which in; its brute force would dash the helpless vessel to pieces against the rocks, being bound and coerced like the genii in Eastern tales, and transformed by man's intellect into a luminous beacon to warn the mariner against the approach of danger. ARTICLE XXIV. — On the various theoretical views regarding the origin of the Primitive Formations. Translated from the German of Carl Freidrich Naumann, {Lehrbuch der Geog- nosie II. 160), by Thomas Macfarlane. The parallel structure, and the stratification of gneiss, mica- schist, etc., have, from the earliest dates of geological history, given rise to the opinion that water must, in some way or other, have had a part in the formation of these rocks. Werner and other geologists believed it to be even possible that they had been deposited from the waters of the ancient ocean, as crystal- line sediments. But seeing that the mineralogical composition of the gneiss does not appear to be compatible with this view, geolo- gists sought to explain the sedimentary origin of these rocks in a somewhat different manner. Thus, Von Beroldingen declared gneiss to be but a regenerated granite, that is to say, a rock result- ing from granitic sand, washed together, in which the mica lami- nae came to be deposited parallel with each other, among the grains of feldspar and quartz. The same view was later enunciated by Bou^ (Essai g^ologique sur I'Ecosse, p. 445), but afterwards Naumann on Primitive Formations, 25 & again abandoned by him. Saussure, also, expressed himself in most decided opposition to Von Beroldingen's views. While narrating that Monte Rosa, from base to summit, consists of gneiss and rocks related to it, he says : " On ne dira done plus, que les granites veines, le gneiss et les autres roches de ce genre, ne sont que les debris des granits, rassembles et agglutines au pied de& baut^s montagnes."* Moreover, (in a note to § 2143 of the work just quoted), Saussure, otherwise mild and delicate in judging and confuting the opinions of others, deals very severely with Von Beroldingen's gneiss theory. f Somewhat related to this old view is the supposition expressed more recently by Dana, that gneiss and mica-schist bear a rela- tion to granite, similar to that in which basaltic tufa stands to basalt, or volcanic tufa to lava ; the materials of these rocks (the gneiss and mica-schist) having been thrown up to the surface before and during the eruptions of the granite, in the form of sand-like ejections, and transformed into gneiss and mica-schist by the action of glowing hot water. The perfect and thoroughly crystalline character of the gneiss, the enormous extent which the primitive formations occupy in so many districts, the archi- tecture of these great gneiss districts, and their occurrence totally independent of larger granitic masses, are all incompatible with this idea. In certain respects the Huttonian theory, which afterwards be- came so influential, may be compared with that of Von Beroldin- gen's, since this celebrated Scottish geologist, in his Theory of the Earth in 1795, attempted, with much minuteness, to prove that the whole of the so-called primitive rocks had been formed of the debris of older preexisting rocks, deposited on the bed of the ocean; the strata, consisting originally of loose materials, hav- ing been, under the pressure of the ocean, exposed to a high tem- perature for a long time, in which manner their consolidation was effected. I * Voyage dans les Alpes, § 2139. t Especially on account of Beroldingen asserting that the opponents of his theory were destitute of all geological knowledge, and saying that the circulation of their writings ought to be prohibited. Beroldin- gen's writings, Saussure thought it was altogether unnecessary to pro- hibit ; " I'extreme d^sordro, I'intol^rable diflfusion, et les perpetuelles contradictions qui y regnent en d^gouteraient assez le plus grand nom- bre des lecteurs." t Compare Explication de Playfair sur la theorie de la tcrrc, par Button, traduit par Basset. 256 Naumann on Primitive Formations. At present there are especially two hypotheses maintained by different parties, regarding the origin of gneiss, and of the rocks associated with it. The first of these theories is founded on the •notion of the metamorphisni of rocks, and the second, on the theory of the originally fused condition of our planet. • The great majority of the geologists of the present day in- cline to the opinion that these oldest cryptogenous rocks, as wel as the recent formations resembling them, have been produced hj a peculiar metamorphosis of preexisting sedimentary strata » consisting essentially in a recrystallisation of the materials of these strata, and caused either by a high temperature, or by mole- cular movements excited in some other way. The supporters of this theory found it especially upon the parallel structure and stratification of these rocks, upon the indis- putable fact that clay-slate in the neighborhood of large granite masses is frequently changed into mica-schist and rocks of a gneissoid character, and upon the scarcely doubtful fact that in many countries, gradual transitions may be followed, from gneiss, through mica-schist and clay-slate, into grey wacke slate. By these transitions, gneiss is brought into such close connection with grey wacke slate, that these appear only as the extreme members of ^ single series ; for the whole of which one and the same original mode of formation must be assumed. Now since greywacke slate is undoubtedly a sedimentary rock, the clay-slate, mica-schist and gneiss lying under it, must have been something similar. But because the mineralogical composition and the crystalline nature of these deeper rocks appear the more opposed to this inference the deeper they lie, the disciples of the metamorphic theory were obliged to suppose the action of a metamorphism working from beneath, which has reacted upon, and so altered these oldest sedi- mentary strata, that they now appear as gneiss and mica-schist. This theory, which at the first glance appears so satisfactory, was first enunciated by Boue in 1822, was afterwards adopted by many other geologists, and found in the year 1833 more decided expression through Lyell,who gave the strata thus altered the name of hypogenous metamorphic rocks ; a title which is intended to indicate a metamorphosis which took place in the depths of the earth's crust, and proceeded from beneath upwards. Properly speaking, these views were very similar to those which Hutton attempted to establish in the years 1V88 and 1Y95,* and bis * His Theory of the Earth appeared for the first time in the Edinburgh Philosophical Transactions for 1788. Naumann on Primitive Formations, ^hl <5omraentator Playfair, in 1802 ; so that it is ia reality possible to maintain that the present theory of the metaraorphic origin of the primitive formations is only a farther development of the Hutton- ian theory, Bou^ however first understood how to bring this theory into more decided harmony with the details of geological phenomena, and besides making use of internal heat, brought emanations of gases and vapors out of the interior of the earth, to his assistance, in order to explain the alteration of sedimentary- slates into gneiss and mica-schist. " La chaleur ign^e," says he, *' et les emanations gazeuses de Tint^rieur de la terre auraient donne aux schistes, peu a peu, et sous une plus ou moins forte compression, une espece de liquefaction ignee, assez serablable a celle dont M, de Dree a fait mention dans ses belles experiences.* Les elemens des schistes auraient perdu de leur force de cohesion, leurs parties constituantes auraient ete ecart^es les unes des autres, at ies emanations gazeuses auraient pu s'insinuer dans les vides ainsi laiss^s. De cette maniere les aflSnites chimiques au- raient pu s'exercer dans certaines limites, posees par les forces adverses de la cohesion, et les parties constituantes des roches auraient pu prendre, pendant la liquefaction et le refroidissement lent, un arrangement plus ou moins crystallin, suivant les circons- tances, et sans deranger ou detruire notableraent la structure feuilletee primitive. De plus, le jeu des aflBnites chimiques, aidee par les substances dtrangeres, inlroduites, pour ainsi dire, par sublimation, dans ces roches, aurait donne naissance a cette foule d'especes minerales crystallines, qui sont diss^minees dans nids, en amas, et en petits filons au milieu des schistes crystallins. Cette theorie hardie pr6sente du moins incontestablement I'avan- tage d^expliquer tous les faits geologique d'une manidre satisfai- sante."t Very many geologists agree with this theory in its principal features. Others, among whom may be especially mentioned Keilhau, Studer and Escher, think it doubtful that the metamor- phosis has been accomplished by high temperature, and by va- pors, and believe rather, that inward transforming processes may have come into operation at ordinary temperatures, whose * De Dr6e described these experiments in the Journal des Mines, No. 139. The principal point to which Boue refers is that the melted or half- melted rocks preserved their texture, and the distribution of their con- stituent particles unchanged, as has also later been shown by Gerhard to be the case with granulite. t Annates des Sciences Naturelles, 1824, Aout, p. 417. Can. Nat. 17 Vol. VII 258 Naumann on Primitive Formations, inferior energy may have been compensated for by their long duration. But while these philosophers do not express a decided opinion regarding the real character of these transforming pro- cesses, G. Bischof and Haidinger are inclined to suppose that a long continued percolation of water through the rocks* has pro- duced a substantial alteration and recrystallization, in the same way as must have taken place in the production of certain altera- tion pseudomorphs.f Many believe it possible to indicate more nearly the sedimentary rocks from which these cryptogenous rocks have been produced. Thus, in 1833, Hitchcock was of opinion that the gneiss had probably been previously a coarse micaceous sandstone, a view which Durocher also adopted, while Forch- hammer believed it possible to prove that the gneiss of Egeberg, near Christiana, was produced from the alum-schist, which occurs there. I We have already remarked however that parallel structure and stratification, cannot in every case, be considered as decisive proofs of sedimentary origin. Even MaccuUoch, in other respects a zealous supporter of the metamorphic theory, admits this. He says expressly that he is obliged to explain the parallelism of the laminae of mica, so often adduced, as a proof of the sedimentary deposition of gneiss, in quite another manner, because even hy- persthenite sometimes shows a parallel deposition of its crystals of hypersthene, and at Kerrera a trap which occurs in veins is, like mica slate, filled with scales of mica, all lying parallel with the aides of the vein. We have also already mentioned the doubts brought forward by Hofi'man and Riviere against the view that widely extended gneiss areas are to be considered as altered sedimentary masses. De * So early as the year 1785, Von Trebra enunciated the view that the alteration of whole mountain masses, for example, of granite into gneiss, and of greywacke into clay slate, had been caused by a very long con- tinued process of alteration, which he characterised as a sort of fermen- tation, and which was produced essentially by the circulation of water, and by the action of heat. Since these causes, which although unper- ceived, are nevertheless thoroughly active, and still at work, and will continue, so as long as circulation goes on in the immeasurable round of nature, he is convinced that the alterations, decompositions and re- compositions which they produce everywhere in the interior of the rocks will continue as long as the world itself.— (Erfahrungen von Innern der Gebirge, p. 48.) t Lehrbuch der Phys. und Chem. Geologic, II. 247. t Journal fiir Praktische Chemie. Bd. 36, 1845, S. 404. Naumann on Primitive Formations, 259 la BecTie expressed himself, even earlier, in the same manner as Riviere, and doubted whether the metamorphic theory (the sweep- ing hypothesis, as he called it) was admissible in such cases, al- though he quite acknowledges it within its proper limits (Report on the Geology of Cornwall, p. 34). With this, A. Erdmann, a high authority with regard to the Swedish primitive rocks, and Von Blode, who has explored Finland in various directions, per- fectly agree. Von BloJe says : that the raetamorphism is un- deniably present where it can be recognised by observation, and explained generally by physical science. Still the class of rocks with which this is the case, is only limited, and not at all favor, able to the baseless hypothesis which is now being carried to ex- tremes. (Neues Jahrbuch fiir Mineralogie, 1844, s. 53.) Von Leonhard, Petzholdt and others, have also repeatedly declared against the too wide extension of the metamorphic theory, and we are obliged, from complete conviction, to rank ourselves with thera^ The transitions from gneiss, through mica-schist, into crystalline clay-slate are not to be denied, but whether the transitions from crystalline clay-slate into real greywacke slate may pass, in every case, for fully proved, may still be doubted. Griiuer re- marks distinctly that the clay-slate which is associated with gneiss- and mica-schist is always diflferent from the clay-slate of the greywacke; for which reason he declares himself unable to assert that these older rocks, as they appear in the departments of the Rhone and Loire, are metamorphosed greywacke slates. (Ann, des Mines, 3ieme serie, t. 19, 1841, p. 70). In our opinion the principal difficulty, and one scarcely to be overcome, lies in the fact that there are far younger gneisses mica-schists, etc., which overlie sedimentary rocks, without the slightest transition into these underlying rocks being observable. In such cases every idea must disappear relative to a hypogenous or anogenous metamorphosis ; for how could the overlying rock have been metamorphosed by some agency from beneath, while the strata beneath remain unaffected by any influence. Just as little can a catogenous metamorphosis be thought of, for what- ever cause one may suppose as the real agency, it is impossible that it can have found in descending, such a sudden and entire check, along one and the same plane of deposition, that the com- pletely re-crystallised rock, should be, by this plane of deposition separated from the perfectly unchanged rock. In such cases there is nothing left for us but the supposition that these strati- 260 Naumann on Primitive Formations, fied, crystalline, silicated rocks, have been originally formed, and deposited, in the state in which they now appear to us. If we are not able to comprehend the modality of their process of for- mation, we can comfort ourselves with the adherents of ultra-meta- morphism, who are quite as much at a loss. After all, it is per- haps immaterial whether we assume a problematical process of alteration, or a problematical process of formation ; but if we were, once for all, to choose between one of the two enigmas, we would probably rather prefer the latter, which at least is in unison with the state of the facts. A second objection against the too wide application of the metamorphic theory, arises out of the fact that many gneissoid rocks shew undoubted evidences of an eruptive origin, and that granulite also, which is so nearly related to gneiss, sometimes occurs under such circum- stances as appear to demand for it an eruptive mode of formation. If this is really the case, it is a proof that certain cryptogenous rocks are decidedly not of metamorphic origin. The great resemblance which gneiss and the most of the rocks accompanying it, bear to granite and other eruptive rocks ; the probability that the most of these eruptive rocks have been solid- ified from a state of igneous fluidity ; the almost unavoidable as- sumption that our planet was originally in the same state, and was only later covered with a solidified crust; finally the fact that in the primitive gneiss formation, granite and gneiss are found regularly interstratified with each other, have called forth the second of the hypotheses prevailing at present; namely, that the primitive formations form the first solidified crust of our planet. This hypothesis has not indeed found so many supporters* as that of the metamorphic origin of the primitive rocks, neverthe- less the objections against it are probably neither greater nor more numerous than against the latter. It leads necessarily to * The following geologists support this theory : Fleurian de Bellevue, (Journal de Physique, an XIII) ; Breislak, (Lehrbuchder Geol., I, 372) ; Cordier, in the third part of his celebrated treatise on the temperature of the interior of the earth, (Ann. des Mines 2, s^rie II, p. 120) ; Marcel de Serres ; Kapp, (Neues Jahrbuch fur Min. 1834, 255, and 1843, 326) ; Von Blode, Neues Jahrbuch fiir Min. 1837, 176; De la Beche, Report on the Geology of Cornwall, &c., 1839, p. 31 ; Petzholdt, Geologic, 1840, p. 24, and 1845, p. 35 ; de Roys, Bull, de la Soc.

Naumann on Primitive Formations, 261 the inference that the succession of the primitive rocks in a down- ward direction, corresponds to their age from oldest to youngest, because it was, of course, through a solidification from the outside inwardly, that the strata in question were formed, (Lehrbuch I, 489). The only way of explaining the origin of the newer cryp- togenous rocks, left to the supporters of this hypothesisi, is to suppose that their material has been protruded from the interior through the earth's crust in an eruptive form. The most considerable difficulties which this hypothesis has to contend with, arise from the relations of the structure of the prim- itive formations, and from the mineralogical character of certain of the rocks belonging to it. Whether these difficulties can be explained away by the supposition of a hydro-pyrogenous devel- opment of the outside'part of the primitive solidified crust, as in- dicated by Angelot, Rozet, Fournet, Scheerer and others, we must leave undecided in the meantime. Scheerer attempted, in a pe- culiar manner, to overcome the difficulties which the structure and architecture of the gneiss present. He regards them as an original phenomenon, produced during the solidification itself, by the action of electro-magnetic currents ; and comes to the final conclusion, " that the primitive formations, with all the di- versity of their rocks, are only to be regarded as the first hardened crust of the solidifying earth." If the vertical position of the primitive gneiss strata, as displayed in their parallel-zoned, fan-shaped and gable-formed architecture, is really to be looked upon as their original position, then the verdict which Kittel thus expressed, must be pronounced correct : " so long as a hy- pothesis is unable thoroughly to explain the almost vertical posi- tion of the primitive strata, it cannot be regarded as even approx- imately near the truth." (Skizze der geogn. Verhaltnisse von Aschafi'enburg, p. 40). Scheerer concludes from the contortions and undulations of the gneiss layers, that the primitive rocks must have originally been in a soft, plastic state, and MaccuUoch, even earlier, ar- rived at the same conclusion, from the surprising contortions of the mica-schist, which he compared with similar windings in the structure of certain basalts. There is probably nothing to be said against the correctness of this deduction, which receives complete confirmation from the so frequently occurring elongation of the constituent of gneiss and other primitive rocks. But whether this plastic condition has been occasioned by high temperature alone, 262 Naumann on Primitive Formations, or by the simultaneous action of heat and water, or only by the latter element, are questions whose solution we must still expect from the future. In the meantime the real mode in which the primitive rocks have been formed, is still involved in such obscurity, that they may, with complete justice, be termed cryptogenous rocks* Note to the preceding paper ; hy T. Sterry Hunt, M.A., F.R.S. The foregoing sketch of the progress of theoretical views as to the origin of the crystalline rocks, gives an excellent statement of the question up to 1857; since which time more definite notions as to the nature of the metamorphic process, as understood by Hntton and Boue, have begun to be entertained. The problem of rock metamorphism is the conversion of mechanical or chem- ical sediments into definite mineral species, by molecular changes; that is to say, by crystallization, and a re-arrangement of their particles; or by chemical reactions between the elements of the sediments. Pseudomorphism, which is the change of one mineral species into another, by the introduction, or the elimination of some element, presupposes metamorphism ; since only the defi- nite mineral species of metamorphic or plutonic rocks can be the subjects of this process. To confound metamorphism with pseu- domorphism, as Bischoff", and others after him have done, is there- fore an error. It may be further remarked, that, although certain pseudomorphic changes may take place in some mineral species, in veins, and near to the surface ; the alteration of great masses of silicated rocks by such a process, is as yet an unproved hy- pothesis. The study of the local metamorphism of sediments in the vicinity of intrusive rocks, goes far to show, in opposition to the opinions of some authors quoted above, that heat has been one of the necessary conditions of metamorphism. In 1857, I showed by experiments, that besides heat and moisture, certain chemical reagents might be requisite, and that water impregnated with alkaline carbonates or silicates, would at a temperature not above that of boiling water, produce chemical reactions among the elements of many sedimentary rocks; dissolving silica and generating various silicates. Some months subsequently, Dau- bree found that in the presence of solution of alkaline silicates, at temperatures above 700° F,, various silicious minerals, such as quartz, feldspar and pyroxene, could be made to assume a crys- talline form ; and that alkaline silicates, under these conditions, Naumann on Primitive Formations, 263 might combine with argillaceous matters to produce feldspar and mica. These observations were the complement of ray own, and both together showed the agency of heated alkaline waters to be sufficient to effect the metamorphism of sediments, by the two modes just mentioned ; namely, by molecular changes, and by chemical reactions. Following upon this, Daubr^e observed that the thermal spring at Plombieres, at a temperature of 160° F., had, in the course of centuries, given rise to the formation of zeolites, and of various other crystalline silicated minerals, among the bricks and cement of the old Roman baths. From this, he was led to suppose that the metamorphism of great regions might have been effected by hot springs; which rising along certain lines of dislocation, and thence spreading laterally, might produce alteration in strata near to the surface; while those beneath would, in some cases, escape alteration. In this way, would be resolved the great difficulty urged by Naumann against the theory of metamorphism by heat from below; namely, that in descending, a certain plane, some- times limits the metamorphism, and separates the altered strata above from the unaltered ones beneath, without any apparent transition between the two. Daubree's ingenious hypotheses of metamorphism by hot springs, in some instances meets this difficulty ; but while undoubt- edly true in certain cases of local alteration, it seems utterly inadequate to explain the complete and universal metamorphism of areas of sedimentary rocks, embracing many hundred thousands of square miles. On the other hand, the study of the origin and distribution of mineral springs, shows that the alkaline waters, whose action in metamorphism I first pointed out, and whose efficient agency Daubree has so beautifully shown, are confined to certain sedimentary deposits, and to certain stratigraphical horizons; above and below which, waters totally unlike in charac- ter, are found impregnating the strata. This fact seems to offer a simple solution of the difficulty advanced by Naumann, and a complete explanation of the theory of metamorphism of deeply buried strata, by the agency of ascending heat; which is operative in producing chemical changes only in those strata in which soluble alkaline salts are present See farther on this subject, the Canadian Naturalist^ vol. iv. page 414 ; the Quarterly Journal of the Geological Society of London^ for 1859, page 488 ; and the Report of the Geological Survey of Canada for 1853-66, page 477. 264 Lawson on Aphis Avence, ARTICLE XXV. — On Aphis Avence^ By George Lawsow, Ph., D., LL.D. (^For the Canadian Naturalist). In my Report an the Insects affecting the Field Crops, &c., in Canada, during the season of 1861, notice was taken of the sud- den appearance of the Wheat or Grain Aphis (not found to b© identical with the Aphis Avenoe of Europe,) in alarming numbers on Wheat, Oats, Rye, &c. During the present season (1862) the insect has played over again the part which it took in 1861^ and which created so much alarm among our farmers. They are better acquainted with the stranger now, knowing that he comes merely to suck the green juicy grain without the means of doing much mischief; but, having obviously become a permanent co- lonist, it is desirable that a few facts connected with his first ap- pearance and settlement in our country should be placed on re- cord in the Canadian Naturalist. In the beginning of August, 1861, ears of wheat infested with this insect were transmitted to me by several farmers and others in the neighbourhood of Kingston, all of whom regarded the in- sect as a new pest to the country. The earliest examples were received from Professor Williamson, Portsmouth, John Duff, Esq., Princess Street, A. Drummond, Esq., Manager of the Mon- treal Bank, Messrs. Piatt, Napanee, and from farmers in the neigh- bourhood of Odessa, and in Pittsburg. A few days afterwards reports were found in the newspapers of its appearance in various parts of Upper and Lower Canada, and over a considerable por- tion of the Northern States ; all reports spoke of the insect as new and unknown to the farmers. More special enquiry among entomological friends and reference to published works, only ser- ved to confirm the surmise that there existed no record or tradi- tion of its previous occurrence in our fields. Prof. Williamson, who had for many years observed with care the insects affecting the crops in this locality, had not previously seen this species of Aphis on any of the grains ; numerous farmers of whom enquiries were made in different parts of the country knew nothing of the insect in former years. And, lastly. Dr. Asa Fitch, the able en- tomologist to the State of New York, whose keen eye has added so much to our knowledge of economic entomology, recognised in the Aphis a new vagabond whose photograph and antecedents required to be reported to the State authorities. The insect is individually minute, like all the Aphides, but pre- Lawson on Aphis Avence, 265 sents a formidable appearance on account of the vastness of its numbers. In some fields, a few days after its first appearance, the ears of grain became covered with it; in fact the wheat was commonly spoken of as " dark with it." The fly presented itself chiefly in the wingless form, the individuals clustering in great numbers in the upper parts of the culms and panicles of wheat, rye, oats and barley, and this season they have been observed on Indian corn and various other grasses. Most of them are station- ary, but some are usually moving about with a rather awkward motion resembling that of mites under a magnifying glass. On each panicle or head of grain they are found to be of various sizes, according to age, some scarcely large enough to be visible to the naked eye, others as large as the capital letters on this printed page. They vary in colour ; some are pale apple-green, some of a brownish yellow colour, and many, especially the older and larger ones, are of a rather deep brick-red colour, when they be- come very conspicuous. In some cases where the whole ears were covered with the insects, the total destruction of the crops seemed to some of the farmers to be inevitable. They looked upon the ** new bug plague " (for everything that looks like an insect is called a bug) as the greatest calamity that had ever be- fallen our fields. It was deemed advisable therefore to publish in the Kingston newspapers an account of the habits of the insect* with the view of allaying unnecessary fears. Attention was drawn to the following among other facts : — The aphides do not gnaw the plant's stem and leaves like caterpillars, nor like the wheat midge, injuriously afi'ect the young grain, but simply suck the juices of the exposed parts of the plant. The plant necessarily 8uff"ers from this injury, its energies are weakened, the leaves and other parts shrivel and blister, and an inroad is formed for other diseases ; but, while aphides are highly injurious to thin and succulent leaved plants, the compact tissue of wheat and other grains, hardened too by silica, is not so liable to suflfer and become deformed, and a vigorous healthy crop of grain will hard- ly be injured. No doubt the yield is lessened by the presence of the insect in vast numbers, and the quality of the grain perhaps slightly deteriorated, but the injurious efi'ects are by no means so extensive as the formidable appearance of the insects would in- dicate. In Britain the bean crop is annually liable to the attacks of an allied black species (Aphis JRumicis) which appears in such nam- 266 Lawson on Aphis Avence, bers that in autumn when many of the individuals have acquired wings and left the bean fields, they spread over the country, dark- ening the atmosphere with living clouds, — yet the farmers do not find their bean crops very light, even during the worst seasons of this so called " cholera fly." Items of information and assurances such as the above served to allay the fears of the farmers, and to prevent unnecessary expenditure of time and money and probable injury to the crops in experimenting with the various remedial applications recommended in the public prints to stay the *' insect plague," such as smearing the standing grain with gum arabic, pulverised hellebore, scotch snufF, flowers of sulphur, aloes and other substances, which, however obnoxious, they might have been to the aphis, would not have improved, by any means, the flavour of the grain and flour. As the season advanced, the aphides increased in numbers, and were no longer confined to wheat, but became abundant and con- spicuous on oats and rye. Daily parcels of grain ears were being received from various ports of the country from farmers who feared that, while entomologists were ferreting out the history of the insect, their crops would in the meantime be eaten up. In the counties of Frontenac, Lennox and Addington, the insect was universal. Wheat proved to be generally light; but the real damage seems to have been done by a less conspicuous but more destructive insect, — the wheat midge, — which was at work early in the season, and, being a sly rogue in grain, was probably not observed by many of the farmers, although quite common in the Kingston district. As the season advanced, the insects preying upon the aphis seemed to increase ; but the most marked eff'ect was observed to result from the heavy rains of the night of Wednesday, 21st, and Thursday, 22d August, which very sensibly reduced the numbers of the aphis. Gardeners say that watering plants overhead rather encourages the production of aphides than otherwise. No doubt aphides like moisture, and especially a moist atmosphere. But it was long ago observed by ray correspondent, Mr. Hardy, of Pen- manshiel, who has devoted special attention to these insects, that heavy rains served to dispel them. During the present season (1862) the aphis has again made its appearance, and in as great numbers as before. It has naturally attracted less notice, but appears to be widely difi'used in all the cultivated parts of central Canada. In August, 1862, 1 traced it Lawson on Aphis AveruB, 267 from Kingston, on the scattered farms along the Addington Road^ back to the township of Olden, a distance of about fit'ty miles. When we consider that many of the farms referred to are mere isolated patches of clearing in the woods, -widely separated from each other, in some cases by miles of interminable forest and swamp, we see that the diflfusion of this insect is totally indepen- dent of its own limited locomotive powers. In its winged state it is no doubt carried in clouds by the winds, like the seeds of thistles and other winged plants. In looking over a general collection of insects, one is struck with the large numbers of species peculiar to certain countries or districts, and which, in spite of their locomotive powers and other means of diffusion, seem to persist in adherence to circumscribed localities. The aphides are of a different character ; those of them which infest cultivated plants may probably, with most truth, be regarded as cosmopolitan, having no special regulating influ- ences that we know of beyond the supply of their food and extremes of climate. They are like the corn weeds that spring up wherever the cereal grains are cultivated, and whose original nativity has been lost. The careful observation of animals and plants of this character, in a new country where settlement is still progressing, is calculated to afford valuable information to the zoological and botanical geographer. The wingless aphides found in such numbers during the sum- mer are all females, but some of the females are winged. Re- markable as it may appear, it is nevertheless true, that the females have the power of bringing forth living young, without any inter- course of the sexes. This may be readily observed by enclosing one under a glass, and observing the production of new individuals, which is regarded by naturalists rather as the result of a process of budding than a true reproductive process. Late in the season, when cold weather comes on, males are produced, all being winged ; they are known from the winged females by the absence of the tail-like process at the apex of the abdomen. The sexes pair, the females lay eggs, these may remain dormant and be hatched during the following spring, and the young issuing from them are females, capable of giving birth, as before mentioned, to successive broods of young, in a viviparous manner, in the absence of males. The reproduction of aphides thus presents some of the most remarkable phenomena with which naturalists are acquainted, 268 Lawson on Aphis Avencd. but which are now explained by corresponding peculiarities in some other groups. A full history of the enquiries of Bonnet and others was given by Mr. Hardy, in a series of papers published some years ago in the Scottish Gardener. Prof. Huxley's important papers " On the Agamic Reproduc- tion and Morphology of Aphis '* will be found in the third part of the 22d volume of the Transactions of the Linnean Society(1858). The following is a detailed description of the wheat or grain aphis : Aphis Aven^. — Plump, pale reddish to brown or apple-green (usually pale-red but very various as regards colour), with black- ish legs and feelers, appears late in summer in colonies, on flow- ering panicles of grasses and cereal grains, becoming winged and leaving the ears, as the season advances and the grain ripens. Viviparous Wingless Female. — Body, medium sized, j^^h. to Y^L^th of an inch in length, oval-oblong, convex with a rim on each side, more or less glossy, especially when mature, varying in colour from pale apple-yellow to deep reddish yellow or reddish brown when young, becoming darker when old ; often of a deep brick-red or chestnut brown, especially on the dorsal surface of the abdomen and other exposed parts, rarely the whole body is of a dull glaucous green, sparsely covered with scattered hairs. The feelers are black, rather more than half the length of the body, rough throughout with bristly hairs, the two basal joints short and thick, especially the first, the terminal one remarkably long and slender, transversely notched throughout its whole length, the intermediate ones four or five times as long as broad (only six joints are developed). The eyes are dark, the rostrum quarter the length of the body, of a yellowish or tawny hue, the terminal joint black, the nectaries almost black. The legs are tawny, the knees, the feet, and the tips of the shanks black, all rather closely covered with bristly hair. Viviparous Winged Female. — Dark brown, sometimes almost black, feelers longer than the body, hairy, dorsal processes of the abdomen (" nectaries") about a fifth the length of the body ; legs dark, the knees, feet, s, you find running actively about in the vial, some lit- tle black flies like small ants. These you see have come out from the dead lice through a circular opening which has been cut in their backs. Drive one or two of these flies into another vial, and intro- duce to them a wheat having some fresh lice. See how the fly runs about among them examining them with its antennsB. Having found one adapted to its wants, watch how dexterously it curves its body forward under its breast, bringing the tip before its face, as if to take aim with its sting. There, the aphis gives a shrug, the fly has pricked it with its sting, an egg has been lodged under its skin, from which will grow^ a maggot like that first seen inside of the dead swollen aphis. And thus the little fly runs busily around among the lice on the wheat heads, stinging one after another, till it exhausts its stock of eggs, a hundred probably or more, thus insuring the death of that number of lice. And of its progeny, fifty we may suppose to be females, by which five thou- sand more will be destroyed. We thus see what effectual agents these parasites are in subduing the insects on which they prey. I find three different species of them now at work in our fields destroying this grain aphis. I have not space here to describe Lawson on Aphis Avence. 271 them. A particular account of them will be given in my Report in the forthcoming volume of Transactions of our State Agricultu- ral Society. And aiding these parasites in the work which they have been created to perform, are several other insects, to which I can only briefly allude. A lady bug or Coccinella (C 9-notata, Herbst) a pretty little beetle, nearly the size and shape of a half pea, of a bright yellow or red color, with nine small black spots, has all season been common in our grain field, it and its larvae feeding on this aphis. Another insect of the same kind, but much smaller and black, with ten yellow dots on its wing covers, (J5ra- chyacantha 10-pustulata, Melsheimer,) is little less common. The Chrosopa, or Goldeneye flies, are also there, placing their white eggs at the summit of slender threads, that their young may feed on these lice. The larvae of diflferent Syrphus flies, small worms shaped like leeches, may also be seen on the grain heads, reaching about as an elephant does with his trunk, till an aphis is found, which is thereupon immediately seized and pulled from its foothold and devoured. " In Britain, the aphides are fed upon by earwigs. We have in Canada a large number of aphides, two of which were very destructive last year. One of them, Aphis Brassicce^ attacks cauliflowers, Brussels sprouts, cabbages, (fee, and another Aphis Cerasi, is very injurious to the cherry tree, especially in orchard houses and sheltered situations. These two species have been fully described in the Proceedings of the Botanical Society of Canada.

With regard to this bird, " the song sparrow," whose nests are built in the immediate contiguity of dwellings, and near every thoroughfare, the following anecdote was told me by Mr. Hunter, the taxidermist to the Natural History Society : On one of his walks to the mountain, close to the footpath of the road leading in that direction, he discovered the nest of one of these birds, covered at the time with a dry leaf. Buildings were being erected in the neighbourhood. Next day on returning to the spot, he found that shavings occupied the place previously used by the leaf, which most carefully concealed the young ones. The colour of the shaving or chip was about that of the young birds at that period of their growth. On visiting next day the nest, the young birds escaped from it. In this instance the instinct of the bird exhibited itself in the employment of a material for the concealment of its nest, the least likely to attract observation from the fact of the erection of a building in the neighbourhood.

SiK, — As I was sitting this morning on the lower step of my veranda, my gaze fixed listlessly, during the noontide heat, upon the gravel- walk before me ; " thinking," I verily believe, ** of nothing," or at most, entertaining a dreamy impression that I was becoming a focus for the concentration of the sun's rays — my eyes were suddenly attracted to an insect whose motions very soon riveted my attention. I at once perceived that it belonged to the order Hymenoptera, but even now that I have the specimen in question before me, I am afraid to name its genus : it is, however, similar to the Tenthredo scropkzdaria, if it is not actually that insect. The accompa- nying sketch may enable you to arrive at a decision on this point : it is the natural size, the length being exactly five lines. The little creature, when I first caught sight of it, had already commenced, within four feet of the spot on which I was seated, its work of excavation ; for as I looked it disappeared, and short- ly afterward returned to the surface of the ground tail first ; and running backward over a tiny mound it had previously made, de- posited a grain of gravel fully as large as its own head outside the mound, with the evident intention that it should not roll back again into the cave it was in process of forming. This operation was continued with great rapidity ; and ever as it re-entered the orifice I saw minute particles of sand fly upward, impelled pur- posely by its descending feet. The care with which the insect distinguished between the larger and the smaller grains was wonderful ; those only whose gravity might have caused them to roll down again, had they been placed below the apex of the mound on the side on which the work was carrying on, were conveyed beyond the mound ; the smaller grains were added to the mound itself without much apparent discrimin- ation. After a time the work was evidently completed to the satisfac- tion of the laborer, for it flew away to the grass-edging of a flow- er-border distant about six feet from the cave, and immediately emerged from thence, dragging after it, for it was running back- 318 Correspondence, ward, the body of a large spider not long dead, — a spider whose bulk was at least three times as great as that of its intending sexton. On arriving within twelve inches of the sepulchre the insect left the corpse, and hastened thither to ascertain, as I can- not doubt, whether or not the orifice was large enough for its admission : it was not so, and the grave-digger resumed his work enlarging, though but very slightly, showing thus how true his eye was, the opening he had made. Returning to the spider he dragged it onward, and, still running backward, pulled it after him within the hole ; and I noticed that so nice had been the calculation, there was exactly sufficient space for the passage of the body — sufficient, but not a hair's-breadth to spare. The insect soon once more emerged, and immediately com- menced filling in the grave, a work he speedily though carefully accomplished. And when that work was completed, he ran round and round with great celerity upon the surface, scattering the gravel in all directions with his feet, with the undoubted object of obliterating every, the faintest mark by which his cache might be discovered : and so efi'ectually was this portion of his operation executed, that half an hour subsequently I was unable, though I searched diligently and anxiously, assisted too by eyes far keener than my own, eyes that had also watched the whole transaction, to find it out myself. Meantime, having sent for ray net, I, not without some feelings of compunction, captured the little workman, and putting him to death by the shortest possible method, made a sketch of him for future reference. Now, what was the object of the little creature in conveying beyond the ken of other insects the booty it had discovered ? My first impression was that it was an Ichneumon, and that it was about to deposit its eggs within the body of the spider ; but Ich- neumons, I believe, invariably make use of living caterpillars for that purpose ; and after having efi'ected my capture, I could dis- cover no trace of an ovijjositor. I imagine, therefore, that it must have intended to make a meal, or many meals oflf the car- case : but why it should have expended so large an amount of time, and given itself so much trouble on that account, I confess I am unable to determine. A reflection, and I conclude. How slender is the line of de- marcation separating instinct from reason ! and how marvellous the Creative Power that could have imparted to an insect so in- Miscellaneous. 319 significant, faculties such as I have attempted, however feebly, to describe ! I have the honour to be, Sir, Your most obedient servant, Vincent Clembnti, B. A., Cantab. Peterboro', C. W., 26th July, 1862. NoT&. — The insect referred to by our correspondent was pro- bably one of the fossorial wasps or Sand-wasps, some species of which have precisely the habit described. Their object is to pro- vide foot for their young ; their eggs being deposited with the spiders or caterpillars which they bury, and the larvae subsisting on the provision thus made for them. Were the specimen sent to us, no doubt the species might be determined. Eds. MISCELLANEOUS. Occurrence of the Blue Grosbeak (Guiraca ccerulea^ Swainson) at Mille Vaches, Lower St. Laiorence. Canadian Ornithologists will be gratified to learn that the beautiful Blue Grosbeak is now for the first time added to the list of birds visiting Canada : — On the Vth of May both sexes of the species were noticed by Mr. Beverley, sen., of Mille Vaches • they were accompanied on the same tree by the little Indigo bird. Mr. Beverley is continually residing in the vicinity of the primitive forests, where he has good opportunities of observing our feathery visitors, and the unusual occurrence of a bird having such brilliant blue colour at once attracted his attention ; he therefore lost no time in securing the male which is stuflfed and in his possession. The habitat of the Blue Grosbeak is the " more Southern States from the Atlantic to Pacific, south to Mexico." Judging from the season, together with the fact of the female having been noticed, there is good evidence that they intended to build in this country. Occurrence of the Stone Chat [Saxicola cenanthe. Bechst.) at Beauport, near Quebec. A single specimen of this pretty bird was procured and stuffed by me ; it is now in the Museum of the Smithsonian Institution, Washington. It also forms an addition to Canadian Ornithology. 320 Miscellaneous. Occurrence of the Yellow Rail {Porzana novehoracensis) in the vicinity of Quebec. Although this handsome little bird is mentionned by Swainson in the " Fauna Boreali Americana " on the authority of Mr. Hut- chins who resided on the coast of Hudson's Bay, near the eflflux of Severn River, I am not aware that it has appeared in any of the published lists of Canadian birds. It is extremely rare in this latitude, only two specimens have been procured during two years 5 both were shot by Mr. G. Campbell of the Quebec Customs ; one is in his possession, and the other he presented to me, which I atuflfed, and is now in the collection of S. Derbishire, Esq. Wm. Coupbr, Quebec. (From proceedings of the Geological Society of London.) On the Geology of the Gold-fields of Nova Scotia. By the Rev. David Honeyman. (Communicated by the President.) The author, at the request of the Provincial Government Com- mission for the International Exhibition, made some observations on the auriferous rocks at Allen's and Laidlow's farms, near the junction of the Halifax and Windsor and the Halifax and Truro railways. He found chloritic schist, with vertical auriferous quartz-veins, and a gold-bearing horizontal quartz- vein (the "bar- rels" of the miners) lying on the schist and overlaid by quartzite and gravel. By the neighbouring railway sections the chlorite- schist is seen to alternate in broad bands with quartzite, and to be associated with granite. The author thinks there is reason to believe that the quartzite may be of Lower Silurian age.

One of the Devonian fossils is apparently allied to the Stomapods, and is named Amphiioeltis paradoxus by Mr. Salter ; it was ob- tained by Mr. Hartt and Dr. Dawson near St. John's, where it occurred with plant-remains ; another Crustacean fossil from the same locality collected by Mr. Payne, is a new Eurypterus^ E. pulicaris. Other remains of Eury2)teri have been sent also by Dr. Dawson, from the coal-measares of Port Hood and the Jog- gins ; and with these a new Amphipod, DiplostT/lus, having some characters of alliance with Typhis and Brachyocelus, MONTIILV METEOROLOGICAL REGISTER, ST.

A Letter addressed to Principal Dawson J dated Albany , October ^ 1862. Having furnished you with a cousiderable number of specimens of DevoDiaa fossil plants, from the State collections, and from my own cabinet, for study and desciiption, I have felt not only great interest in the matter, but much solicitude in regard to the geological position of some of them ; and this feeling has been increased by studying your list of specimens with reference to the geological formations, for it seemed to me that there were some results not quite in accordance with palaeontological laws, and that there was reason to question the geological order assigned to the specimens. • A considerable number* of these had been collected by myself or under my immediate direction many years since, and of these I feel secure ; but there were others which, though obtained from authenticated localities of the Cattskill group^ had not been col- lected by myself ; and in regard to some of these and some of the others not of my own collecting, I believe I expressed doubts, though the greater proportion were reliable. Late investigations, combined with those heretofore made, have forced upon me the conviction that the greater part of the area colored on the geological map of New York as CattsJcill group^'is in fact occupied by the Portage and Chemung groups. Several years since, in making sections across the country from north to south, and through the counties of Albany and Schoharie, I ascertained that the Hamilton group, as indicated by its well marked and characteristic fossils, extends to the southern limit of the coloring indicating Chemung group, on the geological map, I am now prepared to show that the Hamilton group in the counties of Albany, Greene, Schoharie, Otsego, and a part of Chenango, with the exception of some outliers on the higher hills, occupies nearly the entire belt colored as Chemung, the southern line cor- responding very nearly with the limit assigned to that formation ; thus leaving the Chemung group with its southern limits still un- The Investigation of the extent and limitation of this group has been beset with difEcuUies, both towards the west and east of the typical region in southern central New York. In tracing ta^l the eastward the strata of the Chemung group, we find them gra- 378 Pi'of' James Hall on the dually assuming a coarser character, attended by a diminution of the number of fossils, both of individuals and of species. With the accession of coarse materials comes diagonal lamination, and abrupt changes in the nature of the sediment, with other attend- ant features indicating a deposit of littoral character. Until within a few years the State collection had been nearly destitute of fossils from the rocks of Delaware county, which ac- cording to the map is occupied by the Cattskill group. Some time since Prof. Orton, late of the Normal School in Albany, sent to the State Cabinet numerous specimens from the so-called Catts- kill group of that region, and they were thus arranged ; but I readily recognised nearly all of these as characteristic Chemung fossils. Although obtained within the area colored as Cattskill group, it was still possible to suppose that they might have been derived from transported masses, and no investigation having been made to decide this question, the matter rested. More recently, Mr. J. M. Way, of Franklin, Delaware County, has directed his attention to the fossils of his neighbourhood, par- ticularly to the fish remains, which he has found in considerable abundance. From loose and scattered masses he has been able to trace the specimens to their position in the hill slopes, and has ascertained the existence of no less than three distinct beds con- taining these ichthyic remains. Associated with the latter, he has found numerous shells which are typical species of the Chemung group ; and these he has traced to near the tops of the highest hills in Franklin, and occupying large areas of what have been regarded as the unequivocal Cattskill group. Mr. Way has sent collections of these fossil remains to several geologists in the coun- try, with a view of obtaining information to aid him in his re- searches. Having since personally examined the region in question, I do not hesitate to say that we have in the fossil remains taken to- gether the most unequivocal evidence of the occurrence of the Chemung group in these localities. A section from the north side of the Susquehanna river to the high hills in the south part of Franklin gives the following beds, the characters of which I have not yet studied in detail, and the thickness given may be regarded as approximate : — 1. — Greenish-gray sandstones and shaly sandstones ; 100-150 feet to top of hills. CattsUll Group of New York. 379 2. — Fossiliferous band with Scales, bones, and teeth of fishes; Aviculo pectm ? and a few Brachiopoda. (Remains of plants occur a little above the animal remains.) 3. — Greenish and gray sandstones, shaly sandstones and shales; about 150 feet. 4. — Fossiliferous band, containing bones and teeth of fishes ; Brachiopoda and Lamellibranchiata, among which the Spirifer mesostrialis, Hall, is abundant, and Cypricardites chemungensis of Vanuxem is common. 5. — Sandstones and shaly sandstones, similar to those above, but less greenish, and sometimes more heavily bedded ; between 100 and 150 feet. 6. — A fossiliferous band, similar to the one above, with the same species of fossils, and conspicuously marked by a compact argillo-calcareous band with carbonate of iron, and consisting largely of crinoidal remains in small fragments. Crinoidal bands of precisely similar character occur in the Chemung group in the central and western part of the State. Y. — Non-fossi lifer ous shale and shaly sandstone, embracing flag- stones aud sandstones ; about 100 feet. 8. — Red shale and shaly sandstone, with numerous fucoidal remains; 400 to 500 feet. 9. — Greenish and gray shales and shaly sandstones, with darker shales to the top of the Hamilton group ; the thickness not well ascertained. 10. — Hamilton group. Associated with these fossiliferous beds, and more conspicuously with the upper ones, we have bands of a peculiar greenish shaly conglomerate or cornstone, which likewise contain fish remains. These cornstones, with their fossil remains, were noticed by Mr. Vanuxem in his report upon the adjacent country. There is a thickness of between 1,000 and 1,200 feet above the Hamilton group, the lower half of which is not yet known to be fossiliferous beyond the fucoids in the red shaly sandstone. This red shaly sandstone and the dark and green shales below, together with the non-fossiliferous beds of No. Y of the section, represent the Portage group; while the upper members are always marked by characteristic fossils of the Chemung group. I have carried forward observations across the country from the Susquehanna to the Delaware river, and up to the " head of the Delaware " at Stamford ; and I am satisfied that in the region §80 Trof. James Hall on the to the north and west of the we^ branch of the Delaware, and to a great extent (if not entirely) the east and west branches of the Delaware, there are no beds of rock of more recent age than the Chemung ; and, from what I have seen elsewhere, I am in- clined to believe that until we ascend the slopes of the CattskiU mountains, and rise to an elevation of at least 2,000 feet above tide-water, we find no rocks of newer age than the Chemung group. The CattskiU group has been compared with strata newer than the Chemung group, and consisting mainly of red and greenish shales and shaly sandstones. I am now satisfied that the red shaly sandstone near the base of the section, as here presented, has misr led most of those who have heretofore investigated these rocks ; while at the same time the harder and more arenaceous character of the Hamilton rocks in their eastern extension (in which cha- racter they simulate the Chemung rocks,) has caused them to be identified with the latter. I am satisfied, moreover, that through this means Mr. Vanuxem was misled ; and though I have not re- examined the section at Mount Upton, the locality of the charac- teristic bivalve shells, I am not willing to believe it will prove to be newer than Chemung, even if it be much above the top of the Hamilton. You will perceive, therefore, that all the specimens of plants sent you as coming from the CattskiU group are really from beds of the Chemung group proper ; and, so far as possible in this hastily written note, I have given you my reasons for adopting this belief. In looking back to the history of the adoption of the term CattskiU group, it would appear that there was not entire unani- mity as to its signification in some points, among the geologists of the 1st, 3rd, and 4th districts. Prof. Mather, in adopting the term, says it includes Nos. 9, 10, 11, and 12 of the Pennsylvania Survey ; whUe Mr. Vanuxem restricts it to No. 9. As both these gentlemen placed it above the Chemung group as defined in central and western New York, I regarded it (without having made personal examination) as iden- tical with a red shaly sandstone and conglomerate which clearly comes in above the Chemung in the adjacent counties of Penn- sylvania bordering the 4th district. Having considered the Che- mung group as No. 9 of the Pennsylvania Survey, I regarded the red rock with Holoptychus as No. 11 ; the conglomerate. No. 10, CattsJcill Group of New York, S?-t had not been recognised in my district, or adjacent to its southerns limits. I consider that at this time there can be no doubt that the Chemung group is identical with No. 9 in the original nomencla- ture of the Pennsylvania Survey ; and the term Chemung group having been adopted, and well understood in its relations and sig- nification, and well marked by its fossils, we cannot with any propriety continue to extend the term Cattskill group over a large area occupied by the older rocks, and well characterised by their contained fossils. Mr. Mather, in his descriptions of the rocks, has recognized the Chemung group as lying below the Cattskill group, but, as I have shown, the area colored by him as Chemung, is really Hamilton group ; and it now becomes necessary to restrict the term Catts- kill group to the beds above, or to those formerly known as X and XI of the Pennsylvania Survey. Adopting this view, which is imperatively required of us, some modification is necessary in the reference of certain fossils ; but I am satisfied that it will remove one great cause of misunderstand- ing relative to the groups of strata on the confines of the coal measures ; and we shall avoid the complication which must ensue from referring the same species of fossils to two distinct groups of strata, according to the present application of our nomenclature. On reference to the Geological Reports of New York, you will observe that the fossils of the Cattskill group, given in the 1st and 4th Districts, are of plants, with two species of shells. The red shaly sandstone, (called old red sandstone or Catskill group,) rest- ing in outliers on some of the higher hills in the 4th district and occuring in continuous strata in Pennsylvania near the south- ern limit of New York, did not afi*ord specimens of these plants or shells ; while the scales and other remains of Holoptychius are the characteristic fossils of the rocks in these western localities. But so far as I am aware, no scales of Holoptychius have been found in the area colored as Cattskill group in Delaware and the adjacent counties on its west. In tracing the Chemung group westward, there are many indi- cations that it may yet require to be restricted in its desio-nation The Waverly sandstone group of the Ohio Reports, at one timi regarded as entirely equivalent to the Portage and Chemuni groups, may in its upper members constitute a distinct group though we do not yet know any line of demarcation betweei them. 382 Robb on Superficial Deposits of Canada, ARTICLE. XXXV. — Some observations relating to the physical condition of the superficial deposits in Canada, By Charles Robb, Esq. C. E. Montreal. (Read before the Natural History Society^ Nov. 1862.) I. The structure of the fundamental rocks of Western Canada and their geographical boundaries, have been thoroughly ascer- tained and defined by the Provincial geologists ; and from the simplicity of that structure, the regularity of their sequence, and the slight alteration both in position and mineral character, which they have undergone since their original deposition, this part of their task would have been comparatively easy, were it not for the thick masses of clay^ sand and gravel which for the most part envelop and conceal them. Athough the I>rift, as these superfi- cial deposits are called, is one of the most recent of all the geolo- gical formations, its date being immediately before the creation of the existing species of organized beings, it seems remarkable that its precise nature and origin should be less clearly under- stood than those of the more ancient rocks on which it reposes. Apart from the interest attaching to the subject in a purely scien- tific point of view, its investigation is of the utmost practical im- portance in an agricultural country like this ; as such knowledge is calculated to render material aid in understanding the nature and durability of our soils, and in determining the best methods of de- veloping their resources and preventing their deterioration. To these investigations, in so far as they refer to Lower Canada, Dr. Dawson has devoted much attention and made many valuable contributions, and in the Upper Province the researches of Pro- fessor Chapman of Toronto, and of Mr. Robert Bell, under the di- rection of Sir Wm. Logan, have thrown much light on the subject ; and we may shortly expect to be put in possession of the result of their combined labours in a lucid and condensed form by the publication of Sir Wm. Logan's elaborate General Report on the Geology of the Province. The three accomplished observers whom I have named agree, upon independent grounds, in dividing the superficial deposits of Canada into a lower and upper member ; the former consisting chiefly of dark blue and greyish clays, the debris of the under- lying limestone, and nearly destitute of boulders ; and the latter of sand and gravel of granitic and gneissoid origin, with numerous Robh on Superficial Deposits of Canada, 383 boulders. Throughout Lower Canada, and as far west as King- ston, the relative age of these deposits has been determined by appropriate fossils of recent or existing species ; and although these are wanting in the Upper Province, the analogy is presumed to be established by other characteristic features. The fact to which I would desire to call your attention, and which I am not aware of having been previously observed, is that the older forma- tion prevails almost exclusively in Western Canada on the elevat- ed platform bounded on the east and north by the Niagara es- carpment, which sweeps in a bold and abrupt manner from the Niagara river round the head of lake Ontario, and northwards to Cabot's head on Lake Huron, forming a very marked feature in the physical geography of the Province. The whole of the coun- try, for a great distance to the east of this line, and especially to- wards the base of the escarpment, is thickly strewn with sand, gravel and boulders of Laurentian origin ; while to the west these are of very rare occurrence, and are replaced by materials evident- ly derived from the disintegration of the underlying limestone rocks. From the Niagara escarpment westward to the height of land near Woodstock, this difference is less marked than from that point still farther west to the shores of Lake Huron. The influence which I would draw from these facts is one which cor- roborates the view which has been entertained by Sir Charles Lyell and others, who have examined the physical geography of Canada ; namely that the contour of the fundamental rocks of the country has been impressed upon it at an epoch long anterior to glacial or drift period ; and that the elevated platform of the west- ern peninsula, if not actually above the level of the sea at that period, was sufficiently high to resist the intrusion of the ice is- lands charged with the debris of the Laurentian and other more ancient northern rocks, which would be drifted by the glacial cur- rents from the north-east. The chemical composition of the drift clays of the more west- erly parts of the province, as compared with those of the east offers a remarkable corroboration of this view. By the analysis of Mr. Hunt, a specimen of the sub-soil clay from a district west of London, and which may be taken as an exponent of the consti- tuent elements of the clays of the whole western district, yielded not less than 29.40 per cent of carbonate of lime ; while a similar specimen from the Niagara district gave only 15.30 per cent. In fact, in some of the few places in the west where the rocks and S84 Rohh on Superficial Deposits in Canada. calcareous shales are exposed they may be seen decomposing into clay ; while the fossils and fragments of sione found in the clay are sharp and angular, indicating that they have not travelled far from their native beds. Probably this fact of the great excess of calcareous matter in the western soils may account for the supe- rior nature of the timber which grows there, as well as for the su* perior fertility and early period of their vegetation and harvests. ii. Many of the facts connected with the physical condition of the superficial deposits in Canada, and especially of the vast ochre- beds and deposits of marl, bog iron-ore, &c., are attribniable to the existence of powevail chemical actions wliich have been for indefinite periods, and still are in action at no great distance from the surface. I beg to call attention to certain phenomena illus- trative of this subject, which have partly come under my own observation, and partly been related to me by trust-worthy wit- nesses. No doubi similar facts might be discovered in many other parts of the Province, should they happen to come under the notice of competent observers. In the month of October, 1859, 1 visited the farm of a friend who resides on the 1st lot of the broken front range on the road pass- ing through Arkona village, in the township of Bosanquet. This point is, according to the determination of our Provincial Geolo- gists, immediately on the line of j miction of the Corniferous lime- stone and Hamilton shales of the Devonian formation; and as it has been observed that metallic deposits occur most frequently in the neighborhood of such junctions, which may possibly affect their formation, it may reasonably be inferred that some connec- tion exists between the phenomenon I am about to relate and the existenc.e of such deposits. I am not prepared to give an exact explanation of the causes of the proximate chemical reactions which are found in operation at the locahty in question ; still less do I feel competent to offer any solution of the vexed question of the origin and mode of formation of mineral lodes ; I shall simply relate the facts as a slight contribution to our knowledge of the chemical geology of some of the superficial deposits, and possibly also of the formation of metallic veins. The river Sable flows through the lot in question at its north- ern extremity, and at the distance of about 200 yards to the south their occurs upon this lot a tract of low-lying ground Bjobh on Superficial Deposits in Canada. 385 running parallel with it, the intervening space being for the most pa»-t a marl-bed. In this dell or ravine numerous springs exist, which constantly pour forth large quantities of water strongly impregnated with iron; the water on coming to the surface is clear, transparent and colorless, but with a strong ferru- ginous taste ; and very shortly after exposure to the air it yields an oleaginous-looking scum of a highly iridescent appearance, which floats on the surface of the ditches, but quickly dissipates and subsides to the bottom, forming a deposit of hydrated peroxide of iron or ochre, which is found here and in some of the neighboring lots in beds varying from one to three feet in thickness, and of an extent and quality which seems to be economically available, although much mixed with vegetable remains. The springs impregnated with this ferruginous matter penetrate a bed of clay about ten feet in thickness, and where they are strongest appear to have excavated holes in the clay-bed, forming natural wells ; but it is a remarkable fact that they appear to run in veins in a south-easterly direction, as there occurs between two of the strongest springs at a short distance apart another very powerful and deep spring, which is compara- tively free from ferruginous matter. This latter spring which has entirely cut away the clay to a diameter of about six feet, form ing a well as regular as if artificially excavated, apparently yields re- markably pure and clear water, and is intermittent in its action? occasionally throwing up the water with great violence to the heio-ht of about eighteen inches above the surface, as if from the eflfects of gaseous pressure applied under the source of the water. I should here state that the rocks of the country abound in iron pvrites, and loose masses of this substance are found abundantly strewed all around. In this natural well, my friend who resides on the lot found, on probing the quick-sand at the bottom, with a pole to a consider- able depth, a long straight wooden twig about an inch in di ameter, with a little bag of deer-skin tied to one end with a thong of the same material, and coated all over with a bright metallic substance resembling tin, and which on submitting a portion of the stick to my friend Dr. Hunt, he pronounced to be of the fol- lowing nature and origin : " The specimen of wood is very inter- esting, in as much as thehard metallic coating is /row /)yn7e5, formed by the decomposing action of the organic matter of the wood upon the sulphates in the water, in presence of a solution of Can. Nat. 25 Vol. VII. 386 Rohh on Superficial Dejyosits in Canada, iron. The same reaction takes place when oxide of iron is put into a close vessel with any vegetable matter, sulphate of lime being present ; and such, or a similar process, I conceive to have intervened in every case where metallic sulphurets are found in nature." For what purpose the twig with the leather bag had been used and how long it had been immersed in the water, I am unable to stale nor have I had any opportunity of ascertaining the chem- ical composition or temperature of the water yielded by the springs referred to. At one place I observed that the water was very sour to the taste, and probably contained a small proportion of free sulphuric acid. I was informed that occasionally the air in this ravine was oppressively hot and sulphurous, and that when a slio-ht fall of snow would lie in other parts of the lot, it would rapidly melt here. A salt well occurs at no great distance from this place. Towards the southeast of the spot more immediately referred to and at a distance of about half a mile from it, there occurs a series of remarkable pits or depressions in the earth, some long and irregular, but mostly conical or funnel shaped, and ranging in a line with each other and with the hollow where the springs are situated, but at a considerably higher elevation. The conical pits are remarkably regularin shape, and judging by the eye, may be about 50 feet in diameter by about half that in depth. That they are of very recent origin is proved by the fact that in more than one instance I found trees of no very great age growing perpendic- ularly to their sloping sides. I have now to direct attention to a very singular and interesting occurrence at the locality in question, which, taken in connection with the details I have already given may throw some light on the subject of earthquakes and their associated phenomena. The facts I have now to state are given on the authority of my friend who resides on the lot, and whom I know to be a very intelligent and trustworthy observer ; and as it is best that facts of this nature should be given circumstantially, and in the language employed by the observer at the time of their occurrence, I shall quote from his own letter written within two days after the event ; premising that the frame house in which he dwells is situated on a rising ground immediately above, and in full view of the hollow in which the remarkable springs occur. Robb on Superficial Deposits in Canada, 387 BosANQUET, 8th January, 1861. • "One singular occurrence which happened on the 6th inst., I will state as fully as my time will permit. Having retired to bed for the night about 9 o'clock, p. ra., we had scarcely lain down when my wife became alarmed, by the appearance of flashes of light entering our bedroom windows ; and supposing the house on fire, to satisfy her I got up, looked out and around, and found 2lll right. I noticed the flashes of light before my wife did, but supposing she might be alarmed needlessly said nothing. After laying down, it appeared two or three times again, the light continuing for about two seconds or so each time, accompanied at this time by a dull rumbling noise of about six or seven distinct pulsations. The light appeared to shine and the noise to come from a point about four or five chains up the hollow above the large spring north of the house, and within two or three chains of the house. The sky was somewhat clouded at the time ; the sounds were very distinct and abrupt ; and the reflection of the light appeared a mixture of pale red and intensely bright but miH light. " Next morning a neighbour met me on the road, and asked me what I thought of the curious ' phenomenon,' as he called it, we had lately. On asking him what he referred to, he stated that his son-in-law, who has lately built a house on the corner of the clear- ing next to us, and in the line of, and between two of those pits or depressions the range of which I pointed out to you the day you left us — the two pits and house range S. E. with the hollow below our house, where the deep spring is, and about 25 or 30 chains S. E. from the spring — his son-in-law told him that he heard curious noises the previous evening, that the log-house shook, and some tin dishes were thrown from the shelves to the ground and that next morning he observed a line of vapor along the line of the depressions, which vapor seemed to be ejected upwards in several places with considerable force ; it was about daylitrht the next morning that the vapor was seen. I noticed it too when I went out early in the morning, at which time there was a rapid thaw. I went to the great spring to see the eflfect of the thaw on the ditches. I did not then notice any difference, except a depres- sion in a part of the hollow below the spring, as if of late occur- rence, and a large increase in the limbs, twigs, etc., which still continue to be thrown up. For the last two weeks the spring has 388 Rohb on Superficial Deposits in Canada. been precipitating in the channel flowing from it, a very large in- crease of coloring matter, and of a deep clear red color." The inference which I would draw from all the circumstances I have so miuutely detailed is, that powerful chemical reactions are at the place referred to, in constant operation at the surface or in fissures of the rocks underlying the superficial deposits, decom- posing the pyrites and converting it into the sulphate of protoxide of iron, which is soluble in water and is brought to the surface by the springs, and then receiving oxygen from the atmosphere, and being afi'ected by the alkaline solutions also contained in the water, is again changed with the insoluble peroxide and precipitated on the surface of the ground, forming an ochre bed. The abstraction of the material thus displaced will, in the long process of these operations, leave cavities under the surface which must be filled by the subsidence of the superincumbent earth in the same man- ner as is often observed in places where coal beds have been entirely excavated and abandoned. I have little doubt that the remarkable dell or ravine which I have described is of this nature and origin ; and that the series of isolated pits or depressions ranging in the same line with it is only a continuation of it, but at a less advanced stage of formation. To account for the oxidation of the pyrites, which I have sup- posed to be the primary cause of all these phenomena, is not such an easy matter, unless we can conceive it to exist in the bowels of the earth in a minutely subdivided state. " It is well known," says Sir Charles Lyell, " that mixtures of sulphur and iron sunk in the ground and exposed to moisture give out sufficient heat to pass gradually into a state of combustion, and to set fire to any bodies that are near. If a large quantity of clean iron filings be mixed with a still larger proportion of sul- phur, and as much water as is necessary to make them into a firm paste, let the mixture be then buried in the earth and the soil pressed firmly down upon it. In a few hours it will grow warm, and swell so as to raise the ground. Sulphurous vapors will make their way through the crevices and sometimes flames appear. There is rarely an explosion, but when this happens the fire is vivid and if the quantity of materials is considerable, the heat and fire both continue for a long time." The spontaneous combustion of beds of bituminous shale and of the refuse coal thrown out of mines is also generally due to the decomposition of pyrites — and it is the contact of water, E. Billings on Prof. Heirs recent publication, 389 not of air, which brings about the change. A smouldering heat results from the various new combinations, which immediately take place when the sulphur and other substances are set free. Similar effects are often produced in mines where no coaly matter is pre- sent, when substances capable of being decomposed by water are heaped together. This explanation may suffice to explain in a general way not only the production of the ochre beds from the decomposition of pyrites, but also the flames, vapors, and pulsations and subsidence of the ground. The deoxidation of the protoxide of iron dissolved in the water, and its reconversion with the sulphuret through the agency of the organic matter of the wood, is a highly interesting and instructive fact, and throws much light on the origin not only of bog iron ores but on the formation of mineral deposits in general. It affords a striking illustration and coroboration of the theory now generally received among chemical geelogists, that the origin of the metallic sulphurets found so copiously in nature is due to a similar reac- tion through the agency of organic matter on the soluble sulphates contained in the primeval waters ; but on this point we cannot at present enter. ART. XXXVl.—Eemarks upon Prof. HalVs recent publication, entitled : " Contributions to Falceontolo^y." By E. Billings. I have this day (4th November, 1862) received by mail a pub- lication by Professor James Hall of Albany, purporting to be a continuation of Appendix C, of the Fifteenth Annual Report of the Regents of the University of New York. On page 169 there is the following notice : " Twelfth Annual Report of the Regents on the State Cabinet. Tete first seventeen pages of the palajontological part of this Report were printed and stereotyped in January and the early part of February, 1859 ; and nearly one hundred copies were distributed immediately thereafter. The entire report was printed and published previous to the 20th September, 1859 ; and any person, procuring proof sheets from the printer " in the beginning of the month of Jlugust," must have obtained the sheets at least as far as page 56, which had been printed in the early part of July. The proof sheets of the Tenth Report were in like manner procured from the printer , as fast as issued. Similar practices have been resorted to by interested parties, with respect to other reports ; proof- 390 E. Billings on Prof. HalVs recent publication. sheets having been obtained from the printing-office, many months in ad- vance of publication : and I wish simply to record the fact in this place. I had supposed that authors considered such proceedings disreputable, and I scarcely believe that there can be a difference of opinion among gen- tlemen in regard to acts of this kind. [See Canadian Journal of Indus- try and Science, N. S. No. 34, p. 355 ; and Canadian Naturalist and Geologist, Vol vi. No. 4, p. 317.] The two articles, in the "Canadian Naturalist" and "Canadian Journal," referred to at the end of the above quotation were written by me and published under my name ; and it would appear therefore that Professor Hall is desirous of having it understood that I procured the proof sheets of some of his works before publication. In answer to this charge, so unfairly made, I shall only say that I never procured either directly or in- directly a vestige of the proof sheets of any of his works either before or after publication, with one exception, and this by no fault of mine. The circumstances are as follows, and they are well known to him. In Silliman's Journal for July, 1859, p. 149, 1 saw a notice of a pamphlet of 18 pages, published by Prof. Hall. This was the portion of the Twelfth Annual Report referred to by him in the above quotation and which he says was printed in January and February, and published " immediately thereafter." As the criticism in that Journal pointed out that Prof. Hall had described one of my genera under a new name, I na- turally felt desirous of seeing the work. No copy had been sent to our survey, although according to his own showing it had been published five months. I wrote to a friend in Albany to procure one for me. I did not ask for the proof sheets but for the work itself. My friend could not get a copy but sent me several loose leaves, some of which were evidently proof sheets, as they were printed only on one side and had some corrections in the margin. There were 25 pages and 17 of these bad been published as above stated some months previously. The other 8 pages con- tain the genera iVwc^eospVa, dated by him 185Y ; Trematospiray ISSY ; Rhynchospira^ 185*7, Tropidoleptus^ 1856, and part of Leptocoelia 1856.* Now, when an author places dates after the * It is of great importance that the dates of genera and species should be correctly given at first. Many of Prof. Hall's are either er- roneous or ambiguous, I do not admit that those here cited are the true dates. E. Billings on Prof, HaWs recent puhlicofion. 391 names of his genera, he gives the public to nndersland ihrtt he has described the genera in question in some other work, publish- ed at the time indicated by those dates. On Prof. Hall's own showing therefore, the first 17 or 18 pages of the sheets in my possession had been published about five months, and the sub- stance of the other 8 pages two or three years before I procured them. He says that there must have been 56 pages, but this as- sertion is totally untrue; I received only 25.* An intimate friend of his saw them in my room, and informed him that I had some of his proof sheets. This same friend afterwards called and said he had been instructed by Prof. Hall to inquire into the matter. Fearing they might get some innocent person into trouble (although I could not see how), I refused to give him any further information than he possessed ; and, besides, removed the sheets from my office, and never saw them again until this day. The above are all the facts relating to these proof sheets, and the reader can see that it was not intended to take any advantage of Prof. Hall ; and, further, that the work came into my hands in the form of sheets quite accidentally, and with no desire on my part to procure it in that form. Prof. Hall is well aware of all the circumstances, and why cannot he give a true and fair ac- count of them. By blending a mere particle of truth with a great deal that is not true, he has magnified 25 pages obtained uninten- tionally after publication, into whole volumes of proof sheets pro- cured designedly before. This is only a continuation of the un- fair treatment I have received from him during the last four years. It may be that the proof sheets of the tenth and other reports mentioned by him were obtained by parties interested in their contents, but they never were by me ; and yet by a special reference to two articles well known to have been written by me, he makes it appear that I procured them. I would recommend all persons * la one of ray papers I have said 18 pages, but I had not the work before me, and supposed I had only the number mentioned in Silliman. I have, in order to make certain, looked them up and find that there are 1*7 leaves, the first nine of which were printed on both sides, and the other 8 on one side only. There were thus, just 25 printed pages be- sides the title page. The fact of the last 8 leaves being printed ou one side only, convinces me that the work had only proceeded as far as page 25 when these sheets were procured. I shall always believe there- fore that the description of Triplesia on page 44 (of the 12 Rep.) was drawn up after Prof. Hall had seen m^ description of Camerella. 392 E. Billings on Prof, HalVs recent publication, who may have occasion to read Prof. Hall's papers to examine them closely, as it is not unusual for him — especially in questions of priority — to arrive at decidedly erroneous conclusions. I shall now proceed to point out a few palseontological errors in his new work. 1. The genus Cryptonella, illustrated on PI. 3, p. 133, is pre- cisely identical with CharioneUa^ described by me in the Cana- dian Journal of March, 1861, p. 148 and illustrated in the May num- ber, p. 2*73, 274. It includes the species described by Prof. Hall in the Thirteenth Report under the names of Meristella Haskinsi^ M. Barrisi, M. Doris, Terehratula Linckheni. T. rectirostra T, lens, and T.planostria. Besides these the Atrypa scitula oi the N. Y. Reports, C. Circe, and apparently a number of Euro- pean species belong to it. Crijptonella was first published in July or August, 1861, three or four months after the learned author became acquainted with its characters through the study of my papers. 2. Centronetla impressa, PI. 3, figs. 1-5, is C, Hecate published by me in the Canadian Journal, May 1861, p. 272. The date of Prof. Hall's description is July or August of the same year. 3. Euomphalus {StraparoUus) (jlymenioides, PI. 6, fig. 3, is Straparollus Canadensis described by me in the begining of July 1 86 1, in the Canadian Journal Prof. Hall's species was published in October 1861. 4. At page 166 we have the plate with the suppressed figure of Conrad's genus Cypricardites, well copied in full- Palaeontology is indebted to me for the publication of this important plate. Had I not described the genus Cyrtodonta, I fear it would have remained for ever in the dark. The reason given by Prof. Hall for publishing it now is simply that I charged him, in a respectable journal, with holding it in his hands for eighteen years without publication. I here reiterate that charge. There was no mention made of this figure in any of Prof. Hall's publications from the time it was drawn in 1840^ or thereabouts, until the yea 1859. His ideas with regard to the laws of scientific nomenclature are not correct. The rule ap- plicable in this case is, that if a name imply that the genus belongs to a family, order, or class different from that to which it does actually belong, then it should be changed. For example, if the Trilobite Bathynotus were to be called Bathyocrinus or Bathy- E, Billings on Prof, HalVs recent puhlication, 393 osaurus, it could not be retained, no matter how long in use, because it would be absurd to give a Trilobite a name which would imply that it is a Crinoid or a Saurian. So with Cyprkardites, The name implies a close aflSnity with Cypricardia, sl genus of the family OrpRiNiDiE, while the fossils to which Prof. Hall would apply it belong to a different family, Arcade, or rather to a group which appears to form a passage between that family and AvicuLiD^. The name Athyris, quoted by Prof. Hall as afford- ing an analogous case, is quite a different instance. It does not refer the genus to any family, and is only objectionable when used for species with a perforated beak. And for this reason, some of the best palaeontologists reject it altogether. Even Mr. Davidson who still uses it, says that he would have adopted D'Orbigny's generic name Spirigera^ had he not been influenced by other au- thors (British Carboniferous Brachiopoda, p. 79). The greatest authority on the Brachiopoda thus retains Athyris for shells with perforated beaks, simply in deference to the views of others and contrary to his own convictions. 5. The genus Zygospira^ p. 126, is not separable from Atrypa, The connection of the two spires is not of generic importance. The same structure occurs in Spirifera^ some species of which have the spires connected and others not. Atrypa modesta is scarcely distinguishable from A. erratica [Orthis erratica of the Pal. N. Y., Vol. 1), and this latter again passes into A. Headi, In these two species the shell structure is precisely that of A, reticularis. I have referred them to Athyris^ at the same time stating that it would become necesssary to place them in the genus Atrypa^ should the position of the spires be found similar to those of that genus. (See New Species of Lower Silurian Fossils, June 1862, p. 146.) 6. Orthis emacerata^ PI. 2, figs. 1, 2, 3, is not separable from 0. testudinaria. Y. The mistakes with respect to Barrandia and Clioderma were first pointed out by me, and so were the affinities between Rhodocrinus and Thysanocrinus. The corrections are published in this book as if they were original. 8.

My dear Sir, — You have rightly conjectured that I am still interested in Entozoa, and I thank you ranch for your thoughtful consideration in troubling yourself to send me some Cestode pa- rasites. You may be sure Pouchet and Verrier's observations have not escaped me, and I flatter myself very few other authors who write on Entozoology are unknown to me by name or other- wise. The tape-worms you have so kindly sent are very interesting specimens.* I make no doubt that they are referable to the T^NIA PECTINATA, GoCZC.

Nine out of every ten zoologists would have described your worm as a new species, but I protest against the system which some here adopt of never looking up the older writers. Hitherto this worm has only been noticed in the hare {Lepus timidus), rabbit (L. cuniculus), and marmot {Arctomys Mannota), and therefore its occurrence in Hystrix dorsata is a novel fact of very considerable interest. This Cestode is very like (at first sight) a new tape-worm just discovered by Leuckhart, as infesting the human body and dogs in North Greenland (^Bothryocephalus cordatus of Leuckhart) ; but its essential characters are very different. In B. cordatus the * The specimens were obtained from the intestines of the Canada por- cupine {Hystrix dorsata), male and female individuals of which were shot by Mr. Fox and Mr. Moore during one of Prof. Lawson's expeditions to the Rideau and Gananoque Lakes.

Agreable to your directions, I went to Delaware county, to col- lect fossils from the Catskill group, or Old Red Sandstone. At Franklin I found Mr. J. M.

The base is a brick red shale, with occasional red argillaceous sandstone, about 400 feet. On this is about fifty feet of greenish shale ; on which lies a stratum of gray sandstone, with teeth and plates of fishes, and fossils of the Chemung group. Seventy feet of green shale lies on this fossiliferous stratum ; when another thin band of fossils, with gravel and the same formation, continues with alternate shale and gray sandstone and fossils to the top of the hill, where the Chemung fossils are more numerous.

Mr. Way has examined the rock as far as Deposite (twenty- five miles southwest), with great care, and finds the same forma- tion. He has also collected the same fossils at Delhi, seventeen miles southwest. From my investigation, I believe there is no Old Red Sandstone in this State. I found no forms among the fish remains like those of the Old Red Sandstone ot Great Britain, but we have plates far larger than those found there. The Teeth closely resemble those described by Dr. Newberrt, from the Corniferous rocks of Ohio and New York. Respectfully your obedient servant, E. Jewett." MEETING OP ENTOMOLOGISTS. In accordance with the suggestion made in the June number of the Naturalist^ that a meeting of those interested in the study of Entomology, should be held in Toronto, during the Provincial Exhibition, a number of ardent votaries of this branch of science assembled at the residence of Professor Croft, on Friday evening, September 26th. The following gentlemen were present : — Rev. Prof. Hincks, F.L.S., and Prof. Wilson, LL.D., of University College ; Thomas Cottle, Esq., Woodstock ; Thomas Cowdry, Esq.; M.D.,York Mills ; W.L. Lawrason, Esq., London, C. W.; Beverley R. Morris, Esq., M.D., Toronto ; E. Baynes Reed, Esq., and William Saunders, Esq., London, C. W. ; and Rev. C. J. S. Bethune, B.A., Cobourg : — a very fair representation, on the whole, of the En- tomologists in the western portion of the Province. Several Miscellaneoits. 397 gentlemen signified their regret at being unable to attend, in con- sequence of other engagements, while they expressed at the same time their hearty approval of the objects of the meeting. Its first and great object was, naturally, the formation of an Entomological Club, or Society. After some discussion upon the subject, it was decided that, in consequence of the smallness of the number present, no definite org-aoizatioQ should be formed as yet ; but that another meeting should be held during the ensuing spring, due notice of the time and place being previously given to all interested. It was further agreed upon, that the objects of the contemplated society should be, — first, theformation of as com- plete a collection as possible of Canadian Insects, to be kept in some central place for general information and reference ; secondly, the charge of a depository of duplicate specimens contributed by Entomologists for distribution among its members ; and thirdly, the holding of meetings from time to time for mutual information, and the advancement of the science throughout the country at large. The greater portion of the evening was most pleasantly spent in examining and admiring the very extensive and beautiful col- lections of Prof. Croft, as well as those of others kindly contri buted for the occasion. A brief enumeration of their several points of interest will not, it is hoped, be out of place here. First and foremost, must be mentioned the large and varied collections of both native and foreign Insects displayed by Prof. Croft, — among the former, his Longicorns and several other families of Coleoptera, attracted general observation, both from the rarity of many of the specimens, and the completeness of the series; and among the latter, his huge Chinese beetles — including the Di/- nastes Herculi, — and magnificent moths, were veiy much admired. Too much indeed, cannot be said of his various collections, the inspec- tion of which so greatly enhanced the enjoyment of the evening. Dr. Morris exhibited a number of rare specimens of Lepi- doptera, among which may be mentioned Polyommatus epix- anthe, a new addition to our Canadian butterflies ; Darapsa myron, S'phinx Kalmice and other Sphinges ; that pretty Litho- sian Gnophria vittata, etc. He also brought a number of Cole- optera, as well as several interesting specimens of both orders col- lected by him in the neighbourhood of Portland, Me., — of these last, his specimens of Satyrus alope, Strangalia fugax^ Chryso- chus auratuSf and Meloe ? — were particularly fine. Miscellaneous. Mr. Saunders (who took the first prize for his collection of In* Beets at the recent Provincial Exhibition) brought a number of the rarer specimens to the meeting. The most remarkable among them were : — that magnificent butterfly Papilio thoas, not itself a native specimen, but yet highly interesting as being a represen* tative of a species occasionally found in Canada ; Terias liza, Me- litoea 2^limton^ M. ismeria, Thecla acadicay (a new species dis- covered by Mr. S.,) T. niphon, Lyccena Scudderii, (with specimens of which he will be happy to supply any Entomologist,) Foly- ommatus doixas, P. ComyniaSy and other rare butterflies. His undetermined specimens of Hesperidae, and Sphingidse also attracted notice. This gentleman with characteristic liberality, brought also a large case of duplicate specimens for distribution among all who wished for them. Mr. Reed, who had just returned from a visit to the old country, exhibited a complete collection of English butterflies, the speci- mens of which were very perfect, and also some ingenious appa- ratus for collecting purposes, including a pocket butterfly net, lan- tern for attracting Noctuadge, etc. Mr. Lawrason brought a very remarkable specimen of the group Sphingina, captured in the vicinity of London, C. W. It has been submitted to the inspection of several eminent Lepidopterists, and is considered by them as quite sui generis, difi'ering from anything they had ever seen before. Dr. Cowdry exhibited a number of English specimens of Lepi- doptera and Coleoptera, chiefly conspicuous among which were the moths Anthrocera jilipenduloej Callimorpha Jacohoece, seve- ral Cmxulionidce, etc. Rev. Mr. Bethune contributed specimens of several rare insects, including the butterfly Melitoea mylitta ; a very beautiful sphinx, Thyreus nessus ; a new species of Cicindela, some foreign Cetonias, etc. Mr. B. Billings, of Prescott, though unable to attend himself, kindly sent up several cases of interesting specimens, among which were a number of rare and beautiful Longicorns, several £tlaters, some very fine Noctuadoe, and a butterfly new to Canada Polyommatus cratoegi. His brother, Mr E. Billings, of the Geological Survey, Montreal, also contributed a few handsome Chinese specimens, and several rare and interesting native Coleoptera. Miscellaneous, 399 On the whole, it may be safely affirmed that never before in Canada had such large and varied collections of insects been brought together ; the only cause of regret was that there were not more Entomologists to inspect them. The few that were pre- sent, however, enjoyed the occasion to the utmost, only separating at a late hour, with grateful thanks to Prof. Croft for his kind hos- pitality, and unanimous expressions of delight at the pleasant evening they had spent. Thus passed the first meeting of Entomologists ever held in Canada, the inauguration, it is trusted, of better days and brighter prospects for this, hitherto, much-neglected branch of natural science. May the recollection of it serve as a stimulus to incite those who were present to increase their exertions in this delight- ful pursuit, and induce others also to look into the world of in- sects,— an investigation which cannot fail to be replete with unal- loyed pleasure ! c.

(Nuttall), — I have never met with the old bird, but a young bird beside me has the following distinc- tive characters : of the District of Montreal, 403 Bill white, livid on the ridge ; irides red. Dorsal aspect. Crown of head, occipital crest, nuchal region, lower half of the neck on tiie sides, interscapulary region, rump, scapulars and wing coverts, including the primaries, cinereouss brown ; secondaries white, as well as a space between the nostrils and orbit; chin, upper half of the throat, front of the remaining half, and remainder of ventral aspect, including the shoulders white ; silvery on the belly and breast ; the white is tinged on the flanks with cinereous ; the ruff is wanting, but the occipital crest is present. 1st and 2nd primaries subequal and longest; long scapulars equal to the primaries ; length 22 inches ; alar expanse 28 inches ; length of bill from the angle of the mouth 2^ inches. P. minor. Little Grebe. V. s. p. Bill short, strong, compressed, black, with the base of the lower one, white in the adult ; ridge brown, sides and lower one yellowish in the young bird ; legs and feet greenish brown externally, flesh colour internally ; irides reddish brown, dark brown in the young ; eggs 5 to 6 dirty white. Dorsal aspect of a young bird after its first month as it lies be- fore me : Crest wanting ; crown of head brown, varied with yel- lowish brown ; nape of neck and dorsal region including the pri- maries and rump blackish brown with olivaceous reflections, which are wanting in the primaries ; secondaries white on the inner vanes and at the base. Ventral aspect. Chin and middle of the breast and bellv white ; cheeks and sides of throat white tinged with rufous, and with ir- regular streaks and bands of the latter colour ; upper part of the breast and sides banded with rufous brown and black, in which faint white streaks may be discerned ; sides of belly and flanks blackish ash. 2nd primary longest ; 1st and 4th subequal ; long scapulars long- er than the longest primary ; length 11^ inches; alar expanse 16 inches ; length of the bill from the angle of the mouth 1 inch and 2 lines. P. ruhricollis. Red necked Grebe. Colymbiis ruhricollis et subcristatus of Graelin ! Podiceps grisedgena. Baird ! D. c. Bill as long as the head, black, yellow at the base, from 404 Dr, A. Hall o?i the Mammals and Birds the front to the tips 1^ inches; irides reddish brown ; legs and feet black, internally yellowish green ; eggs 3 to 4 whitish green? soiled with yellowish brown. Adult with the cheeks and throat ash colour, neck and breast rufous ; crown and nape with a narrow black space, a short occi- pital black crest, but no ruff; front black; secondaries white ; young duller coloured and spotted ; no occipital crest ; cheeks and throat white, the former striped with black. This bird will likely be found in this district, but I have not hitherto met with it. P. Carolinensis. Red bill Dobchick or Grebe. Colymhus podiceps of Gmelin ! Colymbus Ludovicianus of Catesby ! V. 9. p. Bill pale with a black band across the centre including the nostrils ; legs and feet blackish brown ; irides hazel ; eggs un- known. Dorsal aspect. Crown of head and nape of neck blackish ash colour mixed with cinereous ; dorsal region, rump, and scapular olive brown ; great and small wing coverts, primaries and outer vanes of secondaries brown; inner vanes of secondaries white; cheeks and sides of the neck ashy. Ventral aspect. Chin and orbicular space down the throat jet black ; the remainder of the throat, its sides, and the cheeks as far as the nuchal region cinereous mixed with white ; breast and its sides blackish brown, the feathers broadly tipped with soiled yellow ; belly and sides glossy white, internally cinereous ; the latter colour visible through the white vent and flanks, glossy blackish brown. 2nd primary longest ; 1st shorter than the 3rd but longer than the 4th ; length 13^ inches ; alar expanse 16^ inches ; length of bill from the angle of the mouth 1 J inch. In the young bird the transversal band of the bill is obsolete or at most very faintly de- lineated ; the chin is white, the breast and flanks light chesnut brown, and the belly silvery white tinged with brown. The inner and middle toes of the bird are connected beyond the first articu- lation, and the outer and middle toes are subequal in length. Subgenus Colymhus. Sub gen. char. Bill longer than the head, stout, straight, sub- cylindrical, compressed, with a subulate tip ; nostrils basal, lateral, oblong, semiclosed by a membrane ; feet placed far back ; tarsus of the District of Montreal. 405 compressed ; anterior toes wholly palmated ; hind toe small, bare- ly touching the ground ; wings moderate, small and acuminate : 1st and 2nd primaries longest; tail short, composed of 12 or 10 feathers. This genus appears to be the last of a connecting link between the true palmipedes and those whose toes are free. Their acuminate bill approximates them to the latter, while their really webbed feet induces us to classify them among the former. In general systematic works they have obtained a station after the I>uck tribe ; unjustly so; Cuvier's arrangement is decidedly the best, ranking them in their present position, which I have adopted. C. Septemtrionalis. Red throated Diver. C. striatus ) C. stellatus > Young bird in its different states. C. Itorealis ) C. Septemtrionalis. Baird ! v.s.p. Bill black ; tip brown colour ; legs and feet blackish green ; irides red ; eggs 2, of a pale oil green colour. Dorsal aspect. Crown of head, cheeks and sides of neck lead colour, approaching to black in the centre of the crown ; a stripe along the back of the neck, branching off" to the sides of the neck, black streaked with white ; interscapulary region and scapulars black, with a couple of faint white spots on the tip of each feather ; rump and tail black ; great and small wing coverts brownish black ; primaries and secondaries black, tipped with green brown and white on the inner borders at the base. Ventral aspect. Chin lead colour ; throat with a mesial line of deep purplish red ; breast, belly, vent and tail coverts white ; sides of flanks streaked with black ; inner wing linings white. 1st primary longest ; scapulars short; length 31 inches; alar expanse 37 inches ; length of bill from the rictus 3 inches 1 line ; the lower mandible is navicular ; the upper one is about a line longer than the lower ; the ridge of the upper mandible is inclined to yellowish brown in the specimen before me, and an irregular streak of white runs along the side of the lower one. A female shot in the Lachine rapids in the spring of 1837 and in my possession has the following distinctive characters : Dorsal aspect. Crown, nape of neck cinereous ; dorsal region including the scapulars dark ash colour with a couple of white streaks on the tip of each feather, giving this region a crossed or zigzag appearance ; rump and tail blackish ash ; primaries black, as 406 Dr. A. Hall on the Mammals and Birds well as the secondaries, white on the inner vanes towards the base. Ventral aspect white ; sides of flanks streaked with black. In another female, probably a younger bird, the anterior part of the throat and cheeks is mixed cinereous and white, imparting a gYQ.j or hoary appearance to these regions. The length of the latter specimen is 2*7 inches, that of the former 28 inches. Nut- tal gives as the length of the male bird 29 inches. The stuffed specimen of the male, the description of which is given above, measured as stated 31 inches, probably owing to an irregularity in the manner in which the specimen has been set up. The bird is a rare one in our markets. The male specimens are even rarer than the female. C. glacialis. Loon or Great Northern X>iver. C immer of Gmelin ! Young bird. Colymhus torquatus. Baird ! v.s.p. Bill, legs and feet black ; irides red ; eggs 3 to 4 smoky olive, blotched with umber brown. Dorsal aspect. Crown, cheeks, chin and whole neck jet black, deep black on the head, glossy at the lower part of the neck, with a purple reflection ; on the front of the neck, a narrow band, scarce- ly reaching the sides, and about two inches below it, a collar com- mencing broadly behind and narrowing to the front, white, with broad longitudinal black lines, the black streaks occupying the centre of the feathers ; interscapulary region, scapulars, great and small wing coverts; rump and tail coverts, black, verging to brown on the coverts, with rows of white spots ; these spots being square and in pairs on the scapulars ; suborbicular and in pairs on the dorsal region, and single and round on the coverts and rump ; primaries, secondaries and tail blackish brown, white on the inner vanes of the two former near the base. Ventral aspect. Shoulders white, streaked with black, like the collar ; wing and tail coverts, and breast and belly white ; sides and flanks black, streaked and spotted with white. 1st primary longest; length 34 inches; alar expanse 51 in- ches ; length of the bill from the rictus 4f inches. The female is in every respect analogous to the female of the C. Septemti'io- nalis, but on a larger scale ; the feathers of the head and neck of this bird are uncommonly velvety in feel, and from its approxima- tion to the characters of fur and from its durability is often used for the same purpose by our Aborigines. The C. Arcticus, the of the District of Montreal. 407 only other species of this orenus met with on this continent does not visit us. It is a peculiarly northern sea bird, never met with beyond the sea coasts. Fam. II. Longipennes. Genus Sterna. Gen. char. Bill as long or as longer than the head, compres- sed, slender, more or lest acuminate with sharp edges ; upper mandible, curved at the tip, never hooked, and equal in lencrth to the lower ; nostrils in the middle of the bill, longitudinally cleft and pervious ; legs and feet slender and small, with a naked space above tlie knee ; tarsus shorter than the middle toe ; the 3 front toes webbed ; hind toe very short barely touching the ground ; wings long, acuminate; 1st primary longest; tail of 12 feathers long and forked. ^S'. Hiinindo ? The Great or Common Tern. v.s.p. Bill fine orange, faintly delineated with black, near the tip, which is pale lake ; irides deep hazel ; legs and feet black. Dorsal aspect. Crown, occiput, including the eye, black, des- cending for a short distance down the nuchal region, the remain- der of which, with the rump and tail, is white ; mantle pearl co- lour ; the three first primaries greyish black, the others hoary pearl colour, all of them with a faint streak of white, running longitudinally along the inner vanes ; shafts white ; lower eyelid white. Ventral aspect white. 1st primary longest, the others graduated ; the tail moderate furcate; length from the lateral tail feather to the tip of the bill 20 inches; alar expanse 4G inches; the specimen a female, length of bill from the rictus 3j inches; length of the tarsus If inch. This bird diflers in several particulars from the S. Rirundo of Nuttall, so much so that I feel almost inclined to rank it a se- parate species, were it not for the risk of multiplying species. The points in which they difl'er are the following : S. Hirundo. S. Hirundo ? Crown and occiput wholly black, Crown and occiput wholly black including the eyes. including the e3"e, lower eye- lid white. Mouth bluish white or pale lead Mouth pearl colour. colour. Tail greatly forked. Tail moderately forked.. 408 Dr, A, Hall on the Mammals and Birds Bill reddish yellow or crimson Bill orange, with a faint streak of tipped with black. black on both mandibles near the tip, which is pale. Tarsus red, 1 inch long. Tarsus and web black, the for- mer 1§ inch long. Length 15 inches ; alar expanse Length 20 inches ; alar expanse 30 inches. 46 inches. From this comparative view of these two birds, there can be little doubt but that they are distinct. Under present circum- stances, however, I do not wish to establish a new species, for they are sufficiently numerous ; I much rather prefer ranking it under the head of S. Hirundo with a point of interrogation after it, thus implying my doubt as to its being' in reality the bird men- tioned by authors under that name. The specimen from which my description is taken is in the Museum of the Natural History Society of Montreal. This bird differs also very materially from the Sterna Boysii, S. arctica. Arctic Tern. S. argentea of Brehm ! S' macroura of Newman. Sterna macroura. . Baird ! v.s.p.

Ventral aspect. Cheeks, throat, vent, tail coverts, and wings linings pure white ; all other parts pearl colour. 1st primary longest ; wings extending long over the tail ; length 14 inches ; alar expanse 30 inches ; length of the bill from the rictus 1 inch 9 lines ; tarsus and toes small ; middle toe, without the nail, equal to the tarsus. Li two other specimens before me, the new lateral tail feathers only have their external vanes pearl grev, and not black at all, and all the other tail feathers white. This Tern is the most common one in this district. of the District of Montreal. 409 S. nigra. Black Tern. S.fissipes of Gmelin ! ;S'. ohscura of Latham ! S. plumhea of Wilson ! v.s.p.

The adult plumage in nuptial dress : coverts of wholly blackish ash ; the winter dress of adult birds is lead colour, with the head and neck deep black, and the front, throat and vent white. This bird is not often met with in this district. Genus Larus. Gen. char. Bill moderate, rather stout, straight, compressed, naked at the base, with sharp incurved edges ; upper mandible rounded above with the apex curved ; lower one shorter, gibbous and angular beneath the point which is blunt ; nostrils medial, lateral, longitudinal and open ; tail slender ; thumb small, not touching the ground ; hind nail occasionally wanting ; wings long and acute ; 1st and 2nd primaries subequal and longest ; tail, more or less square, of 12 feathers.

A. Hall 071 the Mammals and Birds with white, the secondaries broadly so ; the closed wings extend- ing two inches beyond the tail. In winter, the hood is wanting, and the young birds have a subterminal band of black on the tail, while their dorsal and ventral aspects are brownish, tipped with rusty white. Length of an adult 17 inches; alar expanse 36 inches. A specimen of this bird is in the Museum of the Nat- ural History Society ; it is a rare one in this vicinity. L. tridactylus. Kittiwake Gull.

Old bird summer plumage. Mantle bluish grey ; 5 exterior quills and outer web of 1st black ; 4th and 5th tipped with white ; all the other parts white. In winter plumage, the occiput and neck are French grey, and the rictu-orbital space streaked with black. A young bird before me presents the following cha- racters : Crown of head, occiput, and scapulars grey skirted with brown- ish white ; rump and wing coverts, except the upper row of the small wing coverts which is brownish black, bluish ash colour ; tail wdiite with a subterminal band of black, and tipped with white ; all the primaries black towards the extremities, the black running down the outer and inner margins in a narrow streak ; the whole outer vanes of the 1st primary black ; all the primaries except the 1st tipped with white ; auriculars brown. Ventral aspect white. 1st primary longest ; length 14 inches ; alar expanse 30 inches ; the tarsus and web have dried pure white, so that I doubt very much whether a black colour, as given by Nuttall, could even characterize this part in the young bird. I have never met with an old specimen. L. canus. Common Gull or Mew. V.S.P.

Billinos, F.G.S. {Read before the Natural History Society of Montreal, 24th Nov., 1862.) The number of insects inflicting injuries upon forest trees by feeding upon the roots, bark, wood, or leaves, is much greater than is generally supposed. Entomologists have ascertained that nearly two hundred species prey upon the English oak alone. In Canada, where there are such vast forests of so many different kinds of trees, there must be quite a multitude of the wood-des- troying tribes to occupy the attention of the naturalist. To work out the history of these, is, to us Canadians, a labor of something more than mere scientific importance ; for there are few countries Billings on the Pine-horing Beetles. 431 whose commercial prosperity depends so largely upon the growth of native woods. Full one fourth of the total value of our export trade is derived from the forests, and there is usually abouk one tenth of the whole province under license from the government to the lumberers for the purpose of making timber * Besides this there are great tracts of land covered with wood of commercial value, in which, the sound of the lumberer's axe has never yet been heard. How long this great source of national wealth is to remain unexhausted, and what are the causes which may some day put an end to so important a branch of our commerce, ate subjects well worthy of serious consideration. It belongs to Canadian En- tomologists to give an answer to one of the several questions that must be discussed during the investigation. I do not profess to know enough of the science to class myself in that body of obser- vers ; but having lived many years in the valley of the Ottawa where there are extensive forests of pine, I have paid some atten- tion to the habits of several of the most prominent of the wood- destroying beetles. I shall this evening give a short account of some of the species, although I do not feel quite sure that Ento moligists will think my remarks of much value. It appears that in Canada we have four species of beetles belong- ing to the longicorn genus Monohamraus. The largest, and apparently the most abundant of these is Monohammus confusor, a magnificent insect, and very destructive to the several kinds of pine timber of this country. The length, exclusive of the antennae, varies from three fourths of an inch to one inch and a half, the majority of the individuals being about thirteen lines. The antennae of the males vary in length from one and a half to three inches ; the female is about the same length as the male, but her antennae are a! ways shorter and her body broader. When very perfect, these insects are of a light ash-grey color, with a few dark brown spots. The grey colour is due to a coat of very *By a reference to the trade returns for the year 1861, it will be seen that our total exports during that year, amounted to $36,614,195, and of this sum the products of the forest made up $9572,645, or somewhat more than one fourth of the whole. Mr. Langton, (Auditor General) says that in 1860 the quantity of land licensed by the government to lum- berers, was" 2 7,413 square miles, or 17,544,320 acres.'!

When these are rubbed off, the head and thorax are seen to be nearly black and smooth and shining, the thoraK being scarcely at all punctured. The elytra, when depriv- ed of the hairs becomes of a horn colour, darkest near the thorax, and covered with small punctures. Some specimens are almost entirely destitute of the dark brown spots, and in general the nnm- !| ber and size of these marks vary a good deal. On each side of the thorax there is a short broad-based spine. The antennae con- sist of eleven joints, the second of which is very short, and the first much thicker than any of the others. This species is found in all parts of Canada where there are pine trees, and Dr. LeConte says it is abundant at Saratoga in New York.^ A specimen has lately been caught flying in the streets of Philadelphia.f •Lk Conte, Jour. Acad. Nat. Sci, Philadelphia, 2d Sec. Vol. 2, p. 148. t Trans. Entomlogical Society of Philadelphia, Vol. 1, p. 98. Billings on the Pine-boring Beetles, 45^- Next in order is Monohammus scutellatus (Say), which is about one fourth smaller than M. confusor, and can always be readily recognized by its dark, nearly black, shining bronze colour ; some of the individuals having a i^ev^ irregular spots of yellowish white scattered over the surface. The thorax and elytra are rugose, with large transverse punctures, or rather short confluent wrinkles dis- tinctly visible to the naked eye. The scutellum is white, the thorax armed with a short spine on each side. The length of this species is usually eight or ten lines, but individuals of from five to eight lines are occasionally met with. The antennae are from' three fourths of an inch to two inches in length. This species, although not so abundant as M. conftcsor, appears to have a more extensive geographical distribution. It occurs in all- parts of Canada, and it is found also in Nova Scotia, and in the Hud- son Bay territories, northward to the Arctic regions. Mr. Couper says it was taken by Sir John Richardson at Fort Simpson on the Mackenzie River, in lat. 62^ N*. Mr. D'Urban says it was pro- cured by Mr. Barnston, from Great Slave Lake, in lat. 54 N.f The third species is Monohammus marmoratus, (Randall). It is described by Le Conte as being very much like M. confusor ; the pincipal difi'erence consisting in the markings of the thorax, which is closely covered with large rugose punctures, while in M. con- fusor this part is not punctured. The antennae are black, and in the female annulated with ash-grey. The elytra are quite sca_ brous at the base from elevated points." Le Conte now unites with it M. maculosus, (Haldimand) and his own two species, M. mutator, and M. fatuor ; the first of the latter two described in Agassiz's Lake Superior, and the last in the Jour. Acad. Nat. Sci. Phi.2d Ser. Vol. 2, p. 148. It is abundant at Lake Superior. I have never seen it ; and if it occurs in the valley of the Ottawa, it must be very rare. The fourth species is J/bttoAa?wmws titillator^\ (Fabricius), Mr. Couper cites it as occuring at Toronto, (Canadian Journal, 1st Ser. Vol. 3. p. 212.)

Nat. 28 Vol. VII. 434 Billings on the Fine-boring Beetles, cimen on which the specios M. titillator was founded is an in- sect from the Southern States, it may be that they have applied the name to our most common and largest species. This question however, remains to be decided by further observations. There are in the collection of McGill College three specimens from Toronto, of the size of the smaller individuals of M. confusor^ which have a light reddish tinge diflferent from the usual colour of that species. I have also seen several specimens from Lake Sim- coe, in the collection of Capt. Rooke of the Scots Fusilier Guards, which seem to be of the same colour as those of McGill College. I have never seen this variety in the valley of the Ottawa, and it may be peculiar to the western part of the province. Whether or not it will constitute a distinct species, remains for our entomo- logists to determine. The first two of these species, M. confusor, and M, scutellatus, attack and destroy great quantities of pine timber. No doubt the other two species do also prey upon the pines, but I have never yet observed them ; and, in fact, they appear to be either rare or of a limited geographical distribution. The trees attacked by them are the white or Weymouth pine, {Pinus strohus) and the red pine, IP, resinosa) the two most valuable timber trees of Canada. The female Monohammus during the summer and autumn lays her eggs in crevices in the bark both of the standing trees, and of those which are dead and lying on the ground. The larva, after being hatched, soon acquires strength of mouth sufficient to enable it to work its way deeply into the wood. There it remains about a year, boring a long winding gallery nearly half an inch in di- ameter sometimes into the very heart of the tree. As the time approaches for its final transformation, it turns, and works out- wards towards the surface ; just before reaching which it enters the chrysalis state. When the perfect beetle is developed, it soon, with its powerful mandibles, gnaws a passage for itself to the open air. I am of opinion that the insect does not come out as soon as the opening is made, for I have often seen them lying quite motionless in iheir burrows, with the head just peeping through. In this position the antennae are not visible, as they are laid back on the sides of the body. On the 20th of July, 1860, while cross- ing Mount Royal, I noticed in a fallen pine tree, on the top of the mountain, several burrows in the bark, which had been lately opened, and were empty. On examining further, I found three others, with the head of a M* confusor filling each j on being Billings on the Pine-boring Beetles, 435 touched they withdrew a short distance, but not out of sight. With the poiT\t of my geological hammer I sooq stripped off the bark, and extracted all three. It seems improbable (although it is possible) that they all arrived at the surface at the same time. It is more probable that after the opening is made, the insect remains for a while, perhaps for a couple of days, iu its burrow, until its elytra become consolidated. Although I have often found large white or yellowish larva, deep in the body of pine trees, I have never been able to ascertain to what species they belonged. This and many other questions relating to the natural history of these insects, remain to be decided by the researches of our entomologists. These insects attack dead timber, and also trees which have received some injury, and are in an unhealthy condition. I have never seen the female laying her eggs on a perfectly healthy and sound pine tree. Timber newly fallen is always attacked by them. The first dwellings constructed in the new settlements are generally made of logs with either the whole or a portion of the bark remain- ing on them. The inside is not plastered, except in the crevices between the logs; if these latter happen to be pine, the Monoham- mus lays her eggs in the bark, on the outside of the house, and for months afterwards the larva may be heard in the stillness of night, making a noise like the boring of a small augur. The per- fect insect sometimes comes out on the inside of the wall, and suddenly drops down upon the floor, the table, or the bed, to the great consternation of the inmates, who imagine that an insect with such great horns must bite or sting with proportionate severity. For the manufacture of boards or planks, the pine trees are cut up into lengths of from 12 to 18 feet, and are either drawn or floated to the mill. The logs are got out during the winter, and if they remain in the mill-yard one season, they are invariably found to be bored through in all directions by larva of these beetles, and the boards greatly deteriorated in value. Where extensive operations are carried on, a single lumberman will some- times have a license giving hini possession of over a hundred square miles of pine forest. In the months of May and June it often happens that great fires sweep through the woods, burning up all the fallen trees and dry branches strewn over the ground, and so scorching the living pines that most of them wither at the top and die during the season. Trees thus injured are soon after 436 Billinprs on the Pine-horing Beetles. attacked by both .Tf. confusor and M. scutellatus, and within one year are so greatly bored that they are unfit for the manufacture of timber. Those experienced in the business, however, well un- derstand the habits of the insect in this respect, and hasten to make the timber before it is destroyed. Pines scorched by the spring fires must be cut down and made into timber the next autumn. After one of these fires it generally happens there is a regular race between the lumberers and the beetles, the prize being a grove of white or red pine. I was told that Messrs. Egan & Co. lost £40,000 worth of timber by some unavoidable delay of a few months. Pine trees, when scorched, would be sound enough for timber five years afterwards, if it were not for the attacks of these formidable destroyers. Where there are only a few pines, as in the neighborhood of this city, it is rare to meet with more than one or two of these beetles together. But in the great forests of the Ottawa it is not unusual to find 15 or 20 on a single tree. On one occasion I saw an extraordinary number, and entered an account of the circum- stances in my note book on the spot. It was on the llth day of September, 1857. I was at that time making some geological observations in the neighbourhood of Lake Clear, in the county of Renfrew. Following an old lumber road through the woods, I came to a place which bad been burned over some time during the preceding spring. There was one large white pine standing on the sunny side of a small gently sloping hill. The height of this tree was about 120 feet, and its diameter nearly 3 feet. About 30 feet at the base was scorched. It was 60 feet to the lowest branch, and as nearly as I could judge, the foliage for 20 feet at the very top, had turned yellow. The remainder was green and apparently healthy. This tree was swarming with M. con/usovy and many of the females were occupied in laying their eggs. I think there were at least 300 of both sexes, and I saw several fly- ing from other trees 30 or 40 yards distant. In flying, the body is not horizontal, butinchned at an angle of only 15° or 20° from the perpendicular. The insects were on all parts of the tree, and they did not appear to take a firm hold of the bark, for a heavy blow with the hammer, at the base, would bring down a dozen at a time, some of them falling from near the top. While falling, they did not attempt to fly. I had 50 or 60 crawling around me at once, and had a fine opportunity to observe the very consider- able variations in the size of the individuals, and length of the . Billings on the Pine-boring Beetles, 43''' antennaB. When two of them going in opposite directions, met face to face, a clumsy kind of afighttook place, in which they reared up and pushed against each other, until one or the other fell over backwards. They bit each other with their mandibles, but with no eflfect that I could perceive. The females fought with each other, or with the males, indifferently. There can be little doubt but that this tree was, during the next twelve months, totally des- troyed. If there were 150 females, and if each laid 200 eggs, and half of these produced a healthy larva, then in one year this tree must have been perforated by 15,000 galleries. I examined other trees in the neighbourhood, and on a few only did I see any of the beetles, usually from one to four or five on each. I can only ac- count for the preference given to this particular tree, by supposing that it was in a better condition for the nourishment of the larva than the others, and that the instinct of the females directed them to it. It is probable that nearly all the females for a considerable distance around were thus brought together on one tree, and were followed by the males. I cannot say whether or not these insects ever attack a perfect- ly healthy and sound tree. I think they do not ; and yet their ravages are certainly highly injurious to the commerce of this country, as they destroy a vast deal of the fallen or scorched tim- ber, which otherwise might be brought to market at any time dur- ing several years after the trees have received their death-blow by fire or storm. I think also that thousands of the trees, only suiB- ciently injured by fire to throw them for a while into a weakly or unhealthy condition, would recover were it not for the attacks of these formidable creatures. The beetles of the genus Monohammus are, as is well known to entomologists, assisted by many species of other genera in the work of destroying pine trees. Canadian naturalists who have selected the wonders of the insect world for their study, have 1>efore them a vast and little- wrought field. In an interesting paper on the trees of Canada, by our colleague, Mr. Robb, it is said that Canada produces "about seventy kinds of timber trees, of which, at present, we make profitable use of not more than eight or ten, the rest being left to absolute decay. Her forests extend over about 360,000 square miles ; and are unrivalled throughout the world for the variety of species, and more partic- cularly for the size of the timber of full growth. Of sixty-four samples sent to the Paris Exhibition of 1855, by Mr. Andrew 438 Zoological Classification, Dickson, of Kingston, one half were collected from an area of one hundred acres. The trees which we find most generally in our woods are the oak, beech, maple, iron-wood, elm, birch, ash, pine, hemlock, tamarack, cedar, poplar, and bass-wood. All these trees attain to a considerable size, and grow to a greater or less extent, in all parts of Canada, except on the coast of Labra- dor, where the only trees that thrive are the white birch, the fir, spruce, beech, and one of the varieties of pine. The trees of smaller growth common to all the country are the hickory, wil- low, alder, wild-cherry, dog-wood, sassafras, and a few others. The black-walnut, tulip-tree, and chesnut are confined exclusively to the western peninsula. Oak and elm are more abundant and of better quality in Canada West than in the eastern part of the province ; but all the other woods attain greater perfection in Canada East." * Now all these trees have their own species of insect persecutors. How many species prey upon each tree ? When does each species deposit its eggs, and in what part of the tree? when is the larva produced, what is its form, and upon what part of the tree does it feed ? how long does it remain in the larval state ? what is the form of the chrysalis,and when does the imago ap- pear ? and lastly ,is there any method of protecting the tree? When all these questions shall have been answered, our entomologists, of which we have now a few good men and true, will have performed a great work. It seems almost impossible to protect a forest against an insect foe, but who knows what may be achieved by patient study ? By accumulating facts, sooner or later, a means of protection may be discovered. At all events, when our interests are threatened by an enemy, it is well to know all about him, his numerical strength and the plan of his operations ; without knowing these we can never hope to discover his weak points.

We are not specially zoologists, but have devoted some atten- tion to the subject in its relations to geology, and as interesting in itself, as well as in connection with the teaching of its? elements to students. We speak, therefore, as addressing zoological spe- cialists from without their own circle, and desire to do so with all the humility becoming this exoteric position. A number of zoologists have lately added to the Cuvierian fourfold division of the animal kingdom, two new types of Pro- tozoa and Coelenterata, the former being probably more widely accepted than the latter, though it also is supported by some high names. We have not been able to convince ourselves of the necessity of either of these groups, in the rank assigned to them; and, on the contrary, fear that their establishment will tend to confuse our conceptions of the natural subdivisions of animals. The group of Protozoa is confessedly distinguished from the others merely by negative characters, — ^by deficiency of impor- tant systems of organs, as of nervous system and organs of sense. It cannot, therefore, be regarded as embodying a type of structure distinct from those of the Radiates, Mollusks, and Articulates^ but rather as embracing all the creatures which are so simple that we cannot recognise in them any distinct type. It is obvious that such a group, however convenient, cannot be recognised as co- ordinate with the others above named, and that it must be merely provisional, containing animals whose afiinities have not yet been ascertained, and which may be humbler members of one or all of the other recognised types. The real question as to the position of these creatures is this. — Can we ascertain their aflBnities? If we can, let us place them in their true relations. If not, let us admit that they do not consitute a veritable sub-kingdom, but merely a residuum which we are unable to classify. Regarding, with Carpenter, the Protozoa as consisting of Phi- zopoda, Porifera, Infusoria, and Grec/arinida,^ it is at once ap- parent : (1.) That all these creatures, in point of simplicity of structure, are as low as, or lower than the humblest members of the other invertebrate kingdoms. (2.) That they do not present, in any distinct form, the types of structure characteristic of these sub-kingdoms. (3.) That many of them strongly resemble the * These latter may possibly be humble Entozoa. 440 Zoological Classification, embryonic or immature stages of certain Radiates^ Mollusks, and Articulates. These statements being admitted, it remains to en- quire whether the balance of affinities inclines to one rather than to the others of these provinces or sub-kingdoms. The great difficulty here is to find any distinct type of structure in these humble creatures, and some of the naturalists best ac- quainted with them hold that no such affinities are to be dis- covered, while others appear to think that their affinities would place them at the base of more than one province. In these cir- cumstances, we are more likely to be guided aright by a conside- ration of the general principles of classification, than by that minute search for distinctions with which zoologists are mor^ familiar. To any philosophical student of animals, it must be apparent that our primary divisions or types are based on considerations of general form, and of the arrangements of the nervous system, and organs of support. On the first of these grounds alone, we must of necessity divide animals into but two groups of Radiata and Bilaterata; on the second, it is equally apparent that we must have two groups of Vertebrata and Invertebrata. There has been of late a tendency among many naturalists to de- ny or overlook the fact that many of the lower animals present, in the words of Agassiz, " a vertical axis, around which the primary elements of their structure are symmetrically arranged," while the main axis of the body cannot, as in the other animals, be regard- ed as a horizontal one, with corresponding parts on its two sides. But nothing can be more illogical than to overlook this general radiated arrangement, because some subordinate parts present traces of bilateral symmetry. It is a mere forcing of nature within the bonds of an arbitrary system. It would be quite as reasonable to deny the prevalence of radiation from an axis or centre in plants, because a is bilateral ; or to maintain that a cuttlefish has no bilateral symmetry because its arms spread from a centre ; or that a man is a radiated animal, because the iris of hiseye is radiated. The Radiata constitute a division of animals asnatural on one ground, as the Vertebrata do on another. Vertebrates^ again, differ from Invertebrates y in the grand dis- tinguishing point of the separation of the principal masses of the nervous system from the general viscera, in a distinct chamber above the centres of the system of support. Zoological Classification. .443. If we separate the Vertebrates on the one hand, and the Radi- ates on the other, there remain the Mollusks and Articulates, groups as markedly distinct from each other, as from the other provinces. We may thus obtain by a somewhat different process from that usually employed, the fourfold Cuvierian classification into sub-kingdoms, and this without leaving any distinct place for the Protozoa as a group of this rank. Let us next inquire if the Protozoa may rank as a class. Agassiz has well shown that our classes, orders, &c., in zoology are not arbitrary or accidental, but based on the relations of our own minds to the actual order of nature. Classes, he maintains, are formed on the manner in which the plan or type embodied in the province is carried out, so far as ways and means are concerned ; and we may add, of course, with a reference to uses or objects. It seems to have occurred to him that this implies a certain and de* finite number of classes to each province, for he has but three in each of his invertebrate provinces; though he subdivides more minutely in the vertebrates, deviating in this, as it appears to us, from the large general view which he has himself expressed. In the Vertebrates four classes have commended themselves to the comnaon sense of mankind, — the mammals, birds, reptiles, and fishes ; and while it is easy, for example, to subdivide the reptiles into two groups, or the fishes into several, these have obviously respectively a less value than the mammals and birds, and conse- quently cannot be classes. What, then, are the ways^ means^ and ends involved in the vertebrate sub-classes ? They are as follows: 1st. The mammal 'implies reproduction without metamorphosis, and the highest development of the sensorium and of intelligence. 2ndly. The bird implies the highest development of the locomo- tive apparatus, and parts subsidiary to this. 3rdly. The reptiles imply development of the merely vegetative hfe. 4thly. Fishes embody the lowest condition of the external members and respi* ratory process, and of the nervous system. A little thought may satisfy us that we cannot suppose a fifth class co-ordinate with these four, however much we may subdivide any one of them. The question remains, do the other provinces admit of more divisions, or of fewer ? K truly co-ordinate with the first, they should admit of the same number, because each type is placed in the same circumstances, in respect to ways, means, and ends. 442 Zoological Classification, In the Articulates we can readily distinguish four classes, cor- responding to those of the Vertebrates : 1st. The arachnidans, with high sensorium and intelligence, and no metamorphosis, and representing the mammalia ; 2nd. The insects, corresponding to the birds ; 3rd. The crustaceans, corresponding to the reptiles ; ith. The worms, corresponding to the fishes. In the MolluskSy we have : 1st. Cephaiopods, corresponding to arachnidans and mammals ; 2nd. Pteropods and gasteropods, cor- responding to birds and insects ; 3rd. Lamellibranchiates, corres- ponding to reptiles and crustaceans; and lastly, the tunicates, brachiopods, and bryozoa present an enlarged representation of the fishes. If the Radiates really constitute a natural group, they should conform to this general plan. Here we have : 1st. Echinoderms, which constitute a class, and the highest of the province ; 2nd. Acalephs,the specially locomotive class; 3rd. Anthozoa, or acti- nozoa, or polyps, the vegetative class ; and lastly, protozoa, with the lowest endowments in respect to internal parts and sensorium. Our Protozoa are thus required in order to bring the Radiates into harmony with the other provinces ; and it seems plain that the group is much nearer its true place as a class, than as a pro- vince. The question still remains, whether some of the Protozoa might not be more naturally placed at the base of other sub-king- doms than those of the Radiates ^ as, for instance, the Vorticellce, with the Bryozoa; Gregarinida and some Infusoria with the worms. It seems likely that this may eventually be done ; and that just as the Bryozoa^ Entozoa^ and Rotifers are now gene- rally separated from Radiates, a more nice analysis of the cha- racters of the more aberrant Protozoa, may enable some of them to be separated from that group. As an additional evidence of the correctness of the view above stated, I may remark that the divisions of Protozoa proposed by Carpenter have much more of the character of orders than of classes, in this respect that they imply rather gradations of rank than different ways and means of execution. Another proof is offered by the strong resemblance of many Protozoa to the embry- onic states of true members of the province Radiata. With respect to the Coelenterata, the case is still more clear. The structural and embryonic evidence given by Agassiz, in his last and the preceding volume, amply prove the aflinity of these Trof, Hall on a New Crustacean* 443 creatures to JEJchinoderms, their radiated structure, and their place in the system as two of the classes of the Radiata. It may be objected that these views savour of the arbitrary methods proposed by MacLeay and Swaiuson. If, however, there is system in nature, it must admit of some general statement ; and the time must come when naturalists will be obliged, by the necessities of the case, to search for and apply such general views. Specialists will object that they must have more subdivisions of animals than those above admitted ; but they have full scope for this in the formation of families, orders, and genera, without at- tempting to disintegrate our higher groups. The family, in par- ticular, as distinct from the order, is a group of great value, and to the cultivation of which their attention might be very properly directed, more especially since the genus is fast losing its impor- tance, from the tendency to erect every little group of species, distinguished by some minute structural peculiarity, into a new genus. Since, however, the greater part of these are clearly nothing but sub-genera, it might be well to have some arrange- ment which might enable them to be recognized for purposes of determination, while the grand generic unity should be maintained by retaining the name of the genus proper, in the nomenclature, with a mark or number to indicate the sub-genus. The views thus slightly outlined are not of yesterday ; but have resulted from much thought on the subject. They are, however, thrown out merely as suggestions for the consideration and criti- cism of naturalists, and in the hope that they may, at least in part, be found to harmonize with the true order of animal nature in its lower forms, as the progress of discovery brings this more distinctly into view. J. W. D. ARTICLE XLll.— On a new Crustacean from the Potsdam sandstone. By Trof. James Hall. A Letter addressed to Principal Dawson, dated Albany, Zlst October, 1862. I have been much interested in reading your observations upon the tracks of Limulus in sand, and comparisons with the tracks in the Potsdam sandstone ;* more especially as these observations connect themselves in a remarkable manner with a recent discov- ery of my own ; and a question may arise as to whether you have * Canadian Naturalist for August, 1862. 444 ^rofs Hall on a New Crustaeean. described an animal which I have found, or I have found the ani- mal corresponding to your description. I will leave you and the scientific world to judge of the facts. However, after what you have written, I cannot now publish what I communicated to the Albany Institute last winter, without referring to your paper, and in the mean time you may lay this note before the Montreal Na- tural History Society, and publish it, or such parts of it, as you please. In February last, I communicated to the Albany Institute a notice of a new crustacean from the Potsdam sandstone of Wisconsin, and subsequently I sent a drawing of the same to M. Barrande. In 1855, I obtained from the Potsdam sandstone of the upper Mississippi River, a fragment of what appeared to be a spine of a crustacean, of very remarkable and peculiar structure, reminding one of that of bone ; and which might at one time, before we had accustomed ourselves to limit the geological range of fishes, have been taken for an ichthyic remain. This fragment remained in my collection a subject of much in- terest, for I was aware from its structure that it could belong to no genus of Trilobites, but at the same time I did not think it worth while to publish any notice of it from its incompleteness. In 1851, Mr. Daniels, of the Geological Survey of Wisconsin, discovered in the Potsdam sandstone of Black River, in that State, tracks similar to those described by Sir W. E. Logan, in the sand- stone of Canada. This added a new interest to the unknown crus- tacean fragment; and in 1860 I visited the Black River region, to procure if possible some of these impressions. I failed how- ever in finding the precise locality ; and in 1862 sent my assis- tant in the Wisconsin survey, Mr. Hale, to make farther explora- tions, but he did not succeed in finding anything of interest. At another locality however, he obtained some fragments of the crus- tacean before mentioned, among which are two cephalic shields suflSciently perfect to be characterized. I inclose you a drawing of one of these. The relations to Limulus are at once suggested by the form and expression of these carapaces, while the large prominent eye- tubercles hold relatively the same position as the small approxi- mate oculiform tubercles or spots on the anterior part of the shield in Limulus, (and also in Eurypterus), The carapace is proportionally flatter than in Limulus ; and has, like that, a strong Trof, Hall on a New Crustacean, 445 thickened border ; the posterior angles rounded. The margin is impressed or sinuate in front, and there are slight indications of longitudinal grooves on each side of the central, leaving a median lobe proportionally wider than in Limulus. The eyes, though imperfect, remind one somewhat of the eyes of Trilobites, and are remarkably prominent. Carapace of jlglaspis from Wisconsin. There is a single fragment of what appears to have been an ar- ticulation of the thorax, or a portion of some appendage analogous to the branchial feet of Limulus ; it has a flattened, curving, point- ed extremity. Another fragment I infer may have been the cau- dal extremity ; it is comparatively thick and strong ; but the spe- cimen is too imperfect to be determined. The first specimen I obtained is a straight spine-like body, and I infer that the animal may have been provided with a caudal spine, as in Limulus. Such, in general, are the characters of this crustacean. Whether this may have been the animal which made the peculiar tracks in the sandstone, I cannot say, but I have so inferred. The first speci- men was found at a distance of thirty miles or more in a north- westerly direction from the locality of the tracks of Black River, and in higher beds of the sandstone. The last found specimens are from a more distant locality, in a southeasterly direction, and also from beds above those of the tracks. All this, however, can- not furnish matter for argument against the origin of the tracks, in the present state of our knowledge of a country which has been comparatively but little exj)lored. Whatever may be proved hereafter in this respect, it does not diminish the great interest attaching to so new and remarkable a form of crustacean from the unequivocal primordial zone of the northwest. Macfarlane on the Acton Copper Mine. 447 ARTICLE XLIII. — Contributions to the History of the Acton Copper Mine. By Thomas Macfarlane. (Read before the Natural History Society of Montreal.) Three years have elapsed since the openiDg of the Acton Cop- per Mine, and probably few mines have in such a short time gained a greater or more merited celebrity. It has been my good fortune to be connected with it since September, 1861, in such a capacity as enabled me to gain much experience as to the na- ture and value of the deposits of copper ore, which are here the objects of mining enterprise. Had it not been for this circum- stance I should not have ventured upon another description of the Acton Mine, seeing that so many valuable papers on the sub- ject are already in our possession. As it is, the few observations which I have made, and which I now proceed to record, are only to be regarded as supplementary to former descriptions, especially to those of Sir W. E. Logan, and the Rev. A. F. Kemp ; and as embracino- a sketch of the progress of the mine from September, 1861, when Messrs. Davies and Dunkin, the proprietors, received the mine back from the lessees who had previously worked it, until the first of October, 1862, when the mine was purchased by the Southeastern Mining Company of Canada. In the month of September, 1861, mining operations were being carried on in the following workings : Flowers's pit, Williams's pit, Harvey's pit, and No. 2 shaft. It is to be observed with regard to these names, that the word pit is applied to an open work- ing of irregular and very considerable dimensions, while the name of shaft is given only to regular sinkings of the usual and smaller dimensions. The position of the above named workings, and the character of the rocks in which they occur, and by which they are bounded, will be seen from the accompanying map. The whole of the open workings occur upon a bed of what has been called in former descriptions " copper limestone," the general strike of which is N.E. and S. W., with a dip more or less inclined to the N. W. Immediately underlying this cupriferous limestone, which is dolomitic, there occur from twenty to eighty feet of dark colored shales, in which, especially near the cupriferous limestone, copper pyrites is frequently found disseminated in thin strings and layers. Beneath this occurs another bed of limestone, of very considerable thickness, the outcrop of which forms the hill run- ning along the south-east side of the mine. Between the cupri- ferous Umestone and the underlying shale, there is often intruded 448 Macfarlane on the Acton Copper Mine. a fine-grained greenstone, which sometimes forms very con- siderable and irregular masses, sometimes intersects the limestone strata, and often presents a peculiar banded structure, resembling more that produced by igneous flow, than that due to deposi- tion from water. This greenstone, although intruded most fre- quently between the underlying shale and the cupriferous lime- stone, is sometimes observed occurring between the latter and the hanging shale. This hanging shale, of a black color, which overlies the cupriferous limestone, is also often impregnated with copper pyrites, and has a very considerable thickness. It has not yet been ascertained what rock overlies the hanging shale in the immediate neighborhood of the mine, but from observa- tions elsewhere, it appears to be followed by lighter colored shales, containing small interstratified quartz veins. Upon these shales is superposed a finely and evenly foliated clay-slate, with transversal cleavage. At greater distances from the mine there is found a considerable development of clay-slates and sandstones ; some of the latter posses-^^ing the characters of the greywacke sandstone of German geologists. The whole of these rocks are apparently destitute of organic remains. According to Sir William E. Logan, they constitute a part of the Quebec group, of the Lower Silurian series Referred to the systems of continental geologists, they ■^ould appear to occupy a place between the primitive slate forma- tion and the Silurian, in a forraation corresponding to Barrande'a Azoic formation in Bohemia, or to the Cambrian system, as this is understood to be constituted by Cotta ; viz., of less crystal- line clay-slates and silicious slate, of non-fossiliferous greywacke sandstone and conglomerate.* Having thus referred to the geological character and age of the rocks in the neighborhood of the mine, I proceed to describe the various workings above named. Flowers's pit, the most north-east- erly of the open workings, has a triangular shape, an average width of forty-five feet, and had in September, 1861, a depth of twenty feet. The bottom of the excavation consisted, on the south-easterly side, of shale, while the outcrop of the cupriferous limestone, hav- ing a thickness of four feet, ran along the north-west side. The original thickness of forty-five feet of limestone, had thus, on account of a fold in the underlying shale, decreased to four feet, as shown in the following section at No. 4 shaft. 'The excavation of the limestone at a was continued, (the point j_*Cotta: Die Flo tz Form^tionen^p. 204. Macfarlane on the Acton Copper Mine, 449 of sliale b having been previously taken down) in the south- westerly half of the opening, along a distance of about sixty feet and to an additional depth of seven feet.* The limestone was more, or less charged with ore along the whole of this distance; but hav- ing in view the disadvantages which attend such large excavations in depth, it was resolved to sink a shaft, in order to examine the Section along the line a — h of the general plan.

Accordingly shaft No. 4 was commenced in the south-west end of the working, and sunk, at intervals, to a depth of seventy-five feet on the inclination of the bed. The first twenty-five feet sunk below the open working was in rock con- taining very good ore, of which rock eighteen and a half cubic fathoms were excavated, and yielded — If 3 5 2 t^°s of first quality ore of 24.0 per cent of copper. 133|i " crush " 2.0 " « These quantities correspond, after deducting the loss in dress- ing the crush ore (one-third of the copper contents), to 18.6 tons of 12 per cent ore, or about one ton per cubic fathom. The co.st of sinking these twenty-five feet, and bringing the rock to the surface, amounted to 8482.94 ; or to 826.10 per cubic fathom of rock, and 825.96 per ton of 12 per cent ore. Below the twenty- five feet the ground was poor ; and in June, 1862, the sinking was discontinued, in order to the stoping of the ore ground on each side of the shaft. Up to the end of July, 45.62 cubic fathoms • It is to be remarked with regard to this and other sections in this paper, that unless when otherwise mentioned, they are not drawn to a scale, and are merely intended to give an idea of the succession of the rarious rocks, without reference to their thickness.

The average thickness of the bed was here 19^ feet, = 3i fathoms. Consequently one square fathom of the bed yielded 8.51 tons of 12 per cent ore, at an expense of $40.92. During the following months of August and September the stoping was continued, accompanied by drifting under the old road lead- ino- into Flowers's pit (see map). Here were excavated 63.37 cubic fathoms of ground, which yielded — 49147 lbs. first quality ore of 21.2 per cent. 23850 u u u u 19.8 u 7114 " second a (( 13.5 il 17600 u .t u u 11.5 (I 40320 " crush (( 5.2 a 134400 (( (( (( 4.1 u 22400 " smalls (( 3.5 11 128427 a a u 2.6 it These quantities, after deducting one-fourth of the copper contents of the crush ore, correspond to 95|||y tons of 12 per cent ore, or 1.5 tons per cubic fathom. The total expense of mining and raising this quantity was $873 ; equal to $13.77 per cuHc fathom, or to $9.19 per ton of ore. The average thickness of the bed was at this place 2^ fathoms. Consequently a square fathom of the bed yielded 3.75 tons of 12 per cent ore, at an expense of $34.32. As regards the north-east extremity of Flowers's pit, a shaft had been sunk in the limestone there previous to September, 1861, to a depth of twenty feet on the incline, below the bottom of the open working, and forty-four feet below the floor, on the present collar of the shaft, now called No. 5. At the bottom, a considerable quantity of copper pyrites was observable, partly in veins permeating the limestone, and partly impregnating the same. In order to the examination of the ground here it was resolved Macfarlane on the Acton Copper Mine. 451 to sink this shaft. The ground gradually improved, and at a depth of fifty-four feet presented an appearance exactly similar to the rich deposits previously excavated on the surface. This ap- pearance has been most suitably and accurately described by Sir W. E. Logan as " a breccia or conglomerate, with a paste com- " posed of variegated and vitreous sulphurets of copper, mingled " with fine grained silicious matter, enclosing fragments of lime- " stone, some angular and some rounded, some of them almost " wholly calcareous and others largely silicious."* The avera^-e thickness of the bed in the ten feet thus sunk, was nine feet, the length of the shaft on the strike of the limestone, twelve feet. From the five cubic fathoms thus excavated, there were produced ^23 1 2 ^^^^ fi^s* quality ore of 22.0 per cent. SSfj " crush " 4.5 " These quantities, after allowing for the loss, correspond to 23.1 tons of 12 per cent ore, or 4.6 tons to the cubic fathom. The costs of raining the above five cubic fathoms, and bringing them to the surface, amounted to $133.33, which is equal to $26.66 per cubic fathom, and to 86.03 per ton of 12 per cent ore. Calculated at the above mentioned thickness of Ij- fathoms, a square fathom of the bed yielded 6.9 tons of 12 per cent ore, and cost 840. The sinking of No. 5 shaft was discontinued during the winter, but re- sumed during the summer, and at the end of July attained a depth of seventy-six feet on the incline. From it, at a depth of sixty feet a gallery was carried towards the west, 30f feet; at which distance from the shaft the limestone was cut off by the hanging wall, every indication seeming to point out the presence here of a left-hand throw. This fault had a direction of N. 10° W. Some stoping was done both above and below this gallery. Up to the end of July there were excavated in shaft, drift and stopes, 65j- cubic fathoms of ground.

The thickness of the bed at this point was 16 J feet, = 2| fathoras. Consequently a square fathom of the bed contained 6.54 tons of 12 per cent ore, and cost $26.73. The limestone in No. 5 shaft gene- rally maintained a dip of from 70° to 80°, and the character of the ore was principally that described by Sir W. E. Logan, as above quoted. The richest specimen assayed from this shaft contained 41.2 per cent copper, and 19.2 per cent of silicious matter. It was not altogether free from limestone. The strike of the bed of limestone from shaft No. 4. to No. 5. is N. 34°. E. Friction grooves have been observed at the junction of both the foot and the hanging shale with the limestone. These generally dip to the west at an angle of about 50°. In August and September, No. 5 shaft was further sunk fifeeen feet, thus reaching a depth of ninety-one feet. The ground between the shaft and the fault above noticed was also stoped out. It was poorer than that previously excavated, but the thickness of the bed increased to twenty-four feet. Immediately to the west of Flowers's pit, there appears to exist one or more powerful faults, which have thrown the cupriferous limestone 140 feet to the right hand. These are indicated on the map, from which it will be seen that the principal one has a di- rection of about east and west, and comes in at the east end of Harvey's pit, where the evidences of the existence of this right hand throw are very striking. It is worthy of remark, that a great accumulation of rich ore was excavated from Flowers's pit, at the point where this fault intersected the one described as oc- curring in the drift to the west of No. 5 ; traces of this are also be found on the surface. These faults, the existence of which was, I believe, first pointed out by Principal Davvsou, will doubt- less be found to influence considerably the ore-bearing qualities of the limestone bed. Harvey's pit is the next open working to the west of Flowers's pit. On the surface it has a length of one hundred, and a breath of eighty feet. A section of the working, at right angles to the direction of the strike, is given on the next page ; from which it will be seen that the same relations exist here as in Flowers's pit, so far as the architecture of the limestone and the underlying shale is con- cerned. The same contraction in the thickness of the limestone is Macfarlane on the Acton Cojrper Mine* 453 visible here, as at Flowers's pit. This rock, before its excavation, bent over the point a, and constituted the arch of limestone men- tioned in a former descriptioo of the mine, by the Rev. A. F. Kemp.* It was on this arch that the first excavation was made in opening the mine. Harvey's pit was last worked in September, 1861. The previous mining had been done very irregularly, and the cupriferous limestone had not been wholly removed; but a con- siderable part of it was left against the hanging wall, as shewn in the following sketch. This Hmestone had, moreover, been sup- Section along the line c — d of the general plan, N. W. S. E. A, hill limestone ; B, underlying shale ; C, cupriferous limestone ; D, hanging shale ; E, greenstone. ported by heavy timbering, which again had been loaded with waste rock. To have taken down the whole of this limestone would have been expensive, and to have cut through it to the hanging wall beneath the timbering would have left the pit in a very unsafe condition. To have sunk a shaft at one end of the pit would probably have been the best plan, had it not been thought preferable to sink or drive from No. 1 shaft, 140 feet northwest of Harvey's pit. These considerations prevented any excavation from being made in this opening ; and, since September, 1861, it has been used as a reservoir for water employed in dress- ing the ore. There is still ore visible in Harvey's pit, nearly in the middle at the deepest point, and on the stope at the west end. The next open working of importance, to the west of Harvey's pit, is Williams's pit. In September, 1861, it was separated from Pike's pit by a piece of ground, since removed, under which a very large drift had been excavated. The east side of Williams's ♦ See Canadian Naturalist, Vol. V. page 360. 454 Macfarlane on the Acton Copper Mine. pit, was worked in September, 1861, and 161^ cubic fathoms of rock excavated. These yielded : 16^i|^ tons, first quality ore of 24.0 per cent. 21111 " crush " 4.5 " which, after deducting loss in dressing, correspond to 85 tons of 12 per cent ore. The eastern stope, consequently, contained 0.52 tons of 12 per cent ore per cubic fathom. The total expense of excavation was $1292.00; or $8 per cubic fathom, and $15.1'7 per ton of 12 per cent. The distance from the underlying to the hanging wall, on the east slope of Williams's pit, is 135 feet ; which extraordinary width is wholly filled up by limestone of slightly different varieties. Next to the foot wall may be observed a fine grained, light grey limestone, with which thin leaves of slate are intercalated, the slate being the more cupriferous. Further to the north-west, there follows a limestone of a coarser grain and slightly darker color, in which the richest copper deposits seem to occur. Por- tions of this are also slaty, but less regularly so than the variety just mentioned! Still further to the northwest, the first mentioned Section from g to h on the general plan, N. W. S. E.

The extraor- dinary thickness which the limestone attains in Williams's pit, seems to be attributable to foldings in its strata. The stratification of the limestone is very obscure, and is rendered more so by innum- Macfarlane on the Acton Coj^per Mine. 455 erable joints, and veins of calcspar, which ramify through the limestone in all directions. Judging however from the position which a certain narrow band of schistose limestone occupies, it appears as if the limestone of the east slope of Williams's pit was stratified as sketched in the preceding section. Between Williams's pit and Pike's pit there existed, as already- mentioned, previous to January, 1862, an arch of limestone; which was perhaps the most picturesque feature of the mine. During the winter, a large quantity of water having accumulated in Wil- liams's pit, and become frozen over, it was judged advantageous to take down the arch, while the access to it by means of the ice was convenient. The piece of ground on the south side of the arch abutting against a huge mass of greenstone, together with the rock above the arch, contained 770 cubic yards = 96 cubic fathoms nearly. These produced : tons first quality ore of 23.0 percent. « crush " 4.7 " {( u u 2.7 " which quantities correspond to 69 J tons of 12 per cent ore. Consequently, a cubic fathom of this rock gave 0.72 tons of 12 per cent ore. The cost of mining and hauling was 8o39, or $5.61 per cubic fathom, and 87.75 per ton of 12 per cent ore. The following is a section of the limestone and the adjoining rocks, at this point, as seen from the north-east side, previous to the ex- cavation : 4 Mil 67 A 54 ^4 Section along the line e—f of the general plan. S.E. N.W. The letters denote the same rocks as in former sketches. The dotted lines show the piece of ground mentioned above. It will be observed that here also there exist evidences of foldings in the 456 Macfarlane on the Acton Copper Mine. limestone strata, and that towards the west end of the mine, the greenstone becomes extensively developed. After blasting down the arch, Williams's pit was not worked un- til May, 1862. By that time, however, it was completely filled with water ; and the quantity contained in it could not, consider- ing the immense area of the excavation, have been much under a million of gallons. Previous to working the pit, it was emptied to within a few feet of the bottom, by means of a syphon made of a two-inch malleable iron pipe, 350 feet in length, leading into No. 1 shaft ; from which the water was raised by the pump attached to the stationary engine there. Blasting was then commenced, and up to the end of July there were excavated 1104 cubic yards = 138 cubic fathoms of limestone, which yielded : 6 If f f tons first quahty ore of 20.0 per cent. 56 IHf " « " 18.4 " 2'7'7 2VV0 " crush « 5.2 « These quantities correspond to 1Y5 -^f^^ ^^^^ of 12 per cent, ore or 1.27 tons per cubic fathom. The total expense of emptying the pit, excavating the rock, and bringing it to the surface, amounted to $1092.29, or $7.91 per cubic fathom, and to $6.24 per ton of 12 per cent ore. Mining was continued in Williams's pit during the months of August and September, and a consider- able part of what constituted the floor of Pike's pit was removed. During these two months there were excavated in all 1468 cubic yards = 183 J cubic fathoms of rock; of which about one-third was in the rich ore-ground on the south-east side of Pike's pit, and the other two-thirds in the much poorer rock situated between the old face of the western stope of Williams's pit and No. 3 shaft. The following lots of ore were produced from the above quantity of rock : 236215 lbs. first quality ore of 19.3 per cent. 169200 U « (( a 19.8 28456 *' second « (( 13.5 120000 a (( u (( 11.5 454720 " crush (( 5.0 680960 U (( (( 3.5 143360 " smalls u 2.8 327040 U (( u 3.5 These, after deducting one-fourth of the copper contents of the crush ore, are equal to 507 ^f || tons of 12 per cent ore. Con- Macfarlane on the Acton Copper Mine, 457 sequently, a cubic fathom of this rock yielded 2.Y6 tons of 12 per cent ore. The total expense of niining and hauling to surface was 8l'777.12, or $9.68 per cubic fathom, and 83.50 per ton of 12 per cent ore. The width of the limestone horizontally across "Williams's pit, at this point, is 150 feet; the width of the stope nine fathoms. If we assume the thickness of the limestone, at right angles to the underlying shale, to be twelve fathoms, which is evidently a moderate estimate, then a square fathom, along the plane of the bed at this point, contains 33.12 tons of 12 per cent ore. In the upper part of Williams's pit, the conglomerate charac- ter of the cupriferous limestone, referred to in describing No. 5 shaft, is beautifully developed. Masses of this character have fre- quently been blasted out, measuring at least eight cubic yards. A large mass of nearly the same dimensions was found loose on the surface of this deposit. On drilling a hole into it, preparatory to blasting it, the borings obtained were carefully collected and examined. They contained : Silica, 36.98 Carbonate of lime, 4.64 Alumina, 0.84 Iron, 7.01 Copper, 34.20 by assay. Sulphur, 16.33 by difference. 100.00 The three last ingredients calculated to 100 parts give Iron, 12.18 Copper, 59.44 Sulphur, 28.38 100.00 which figures approximate pretty closely to some analyses of pur- ple copper. In the bottom of Williams's pit, about forty feet below where this mass was found, the ore is more solid, not so much diffused through the limestone, but concentrated in veins, which are pretty distinctly separated from the side rock. In one of these, of considerable thickness, I found the purest purple copper which I have yet observed on the mine. It contained neither lime nor silica, and assayed 61.9 per cent of copper. At no great ^ 458 Macfarlane on the Acton Copper Mine, distance from this vein, the limestone was destitute of copper, and had the following composition : Silica, 1.50 Alumina and peroxide of iron, 2.85 Carbonate of lime, 'Zl.lO Carbonate of magnesia, 24.12 99.57 Previous to September, 1861, No. 2 shaft had been sunk through shale, and into the limestone to a depth of seventy-eight feet ; and a drift carried from it, at this depth, both towards the hanging wall, and towards the foot wall. The direction of this drift was N. 10° E. ; consequently not at all at right angles to the direction of the strike, (which in this part of the mine appears to be N. 20^ E.) ; but rather parallel with it. The length of the drift from the shaft to the hanging wall was forty-two feet, to the foot wall sixty feet. This latter, which was partially cut through, was found to be of greenstone, or rather a shaly greenstone, composed of alternate layers of that rock, and of shale with copper pyrites. This con- stituted at least the lower part of the face of the drift. The upper part was of limestone. In view of these circumstances, and although a gallery had been driven twenty-seven feet along this foot wall to the west, it was deemed proper to continue the main drift. This was done for a distance of sixty feet in the same direction of N. 10° E., always in limestone ; the bottom of the drift consisting almost the whole distance of the same shaly greenstone. Some good patches of purple copper were met with, and also some veins of calcspar with purple copper and copper pyrites, dropping down from above ; these veins led to the belief that the drift was being carried along underneath the ore. At the distance of 1 20 feet from the shaft, the direction of the drift was altered to N. 63° W. (iu order to meet No. 3 shaft) ; the drift was then carried sixty-three feet further, al- ways on the foot wall, which gradually rose, until the driving was dis- continued ; when it was found to have an inclination to the N. W, of 40°. In driving this sixty-three feet, some little copper was discov- ered, principally in veins of calcspar from one to three inches thick. Shortly after the driving here was discontinued, No. 3 shaft, which was meanwhile being sunk, was carried down to the drift, and made to communicate with it. No. 3 shaft had, previous to Sep- tember, 1861, a depth under the floor of Pike's pit, of twenty- Macfarlane on the Acton Copper Mine, 459 six and a half feet. In March and April it was further sunk twenty-seven and a half feet, and at the depth of fifty-four feet it broke through into No. 2 drift. The last six feet sunk was in poor rock, but, previous to this, twelve feet had been sunk through cupriferous limestone, permeated by veins of calcspar and quartz, containing purple copper. One of these veins seemed, in the southeast corner of the shaft, to have a dip of about 45° to the N. W., but on the opposite side it became very much flatter This circumstance seemed to confirm the opinion that No. 2. drift had been carried along underneath the copper, so that it was determined to stope back from No. 3 shaft, overhead in the drift. In a short time the few feet of poor rock constituting the roof of the drift were removed, and a bed of limestone exposed, con- taining numerous veins consisting of purple copper and silicious matter, and presenting an appearance similar to that described as occurring in the bottom of Williams's pit. The following sketch is a section along a line running from No. 2 shaft to No. 3, and thence across Williams's pit : Section from i to ^, and thence to I, on the general plan. S.E. N.w. A, hill limestone; B, underlying shale; C, cupriferous limestone; D, hanging shale ; E, greenstone ; C2, dark coloured silicious lime- stone, distinctly stratified, with impregnating copper pyrites. It will be observed that a jog or bend of the footwall occurs in No. 2 drift, similar to those occurring at the surface in Harvey's pit and Flowers's pit ; and that it was in the basin thus formed, and a little from the bottom of the same, that the rich ore at a was discovered. The excavation of ore at this point, by widening the drift and stoping overhead, commenced on the 1st of June. From that date until the 8th of August, 573 cubic yards = 71.6 cubio fathoms were excavated. These produced : 460 Macfarlane on the Acton Copper Mine. ^zHs ^^"s first quality ore of 22.0 per cent. l^s-VsV " " " " 18.4 " HMi " " " " 24.0 " 2///^ " second " " 9.0 " 269 " crush " 4.2 " corresponding to lOl/j"/^ tons of 12 per cent ore, or 1.41 tons per cubic fathom. The total expense of mining and bringing to surface was $1288, or $18 per cubic fathom, and $12.71 per ton of 12 per cent ore. Mining was continued here after the above date, but up to the end of September no further measurement had taken place. Probably nowhere else on the mine are such beautiful and distinct specimens of the copper conglomerate, or rather breccia, observable, as in the excavation above No. 2 drift. In many cases the line of division between the cupreous matrix and calcareous fragments is sharp and distinct ; and it not unfrequently happens that there may be found in close proximity to each other, pieces of matrix almost free from lime, and fragments of limestone containing not a trace of copper. To judge from the appearances in No. 2 drift, the cupriferous limestone there does not contain a definite bed of conglomerate running irregularly through, and subordinate to it. It seems rather that the limestone has been cracked in all directions, and is now filled with a network of veins from an inch to two and a half feet thick, and containing purple copper, copper pyrites, silicious matter, and fragments of limestone. The matter of these veins has so often a brecciated character, from the presence of angular fragments of the adjoining limestone, as frequently to entitle it to the old German name of" Gang brockengestein," a term sometimes used for characterising this brecciated structure in veins. The accompanying sketch shews a section of one of these veins cut through in stoping upwards from No. 2 drift. The following analysis was made of a piece of veinstone, from the same vein which enclosed a well defined angular fragment of limestone : Silica 38.65 Carbonate of lime, 0.95 Iron.... 7.31 Copper 37.20 Sulphur, 15.89 by diflference. 100.00 I I 462 Macfarlane on the Acton Copper Mi me.

I have thus described the progress of the mine, and the results obtained in the various productive workings during the thirteen months ending 30th September, 1862. If we take the average of these results, we find that the average produce per cubic fathom has been 1.6 tons of 12 per cent ore ; the average cost of mining and bringing to surface, $11.28 per cubic fathom, and $7.03 per ton of 12 per cent ore. These, it will be observed, are the results of minino- in the produclive part of the cupriferous bed, exclusive al- together of the cost of explorative work, of which latter it was only in No. 2 drift that any considerable amount was done. Pro- bably the cost of prospective work did not exceed $1.50 on each ton of ore produced; so that we may assume that the cost of searching for ore, mining and bringing it to the surface, was $8.50 per ton of 12 per cent. Before leaving this part of the subject, I may be per.nitted to make some remarks as to the nature of the deposit and the source of the ore. It will probably be admitted on all hands, that the bed of limestone in which the ore occurs, is of sedimentary origin, and originally possessed a horizontal position. Nor will it pro- bably be denied, that a part at least of the copper ; viz., that part which occurs in the form of copper pyrites, finely disseminated through some parts of the rock, was deposited, in some state or other, simultaneously with the limestone. That the limestone and the rocks adjoining it have, by certain powerful agencies, been raised from their horizontal position, and in this process been Macjarlane on the Acton Copper Mine, 463 rent, broken, bent and twisted in the most violent manner, is evi- dent from the various phenomena presented in every part of the mine. Whether this upheaval was caused by the greenstones being thrown up from beneath, seems to be uncertain, but it is probably not unreasonable to suppose that this protrusion of the greenstone occurred simultaneously with the upheaval of the strata ; and that both may have been caused by certain more gen- eral and wide spread movements of the earth's crust. Whatever may have caused the upheaval, it seems sufficiently evident that the upheaval caused the rending of the limestone, the formation of the fissures and crevices, in which the copper ore was subsequently deposited, and the partial filling up of these by detached fragments of limestone of all possible dimensions. With regard to the fill- ing up of the fissures by the copper ores, we may conceive three different modes in which this may have been eff'ected : 1. The ores may have been injected into these fissures in a fused state* 2. They may have been removed from the impregnated side rock by certain solvents, and re-deposited in the fissures. 3. They may have been brought up from beneath by springs. With re- gard to the first of these theories, it must be remarked that the general appearance of the veins, coupled with the presence of green- stone in the neighborhood, would seem to be in its favor. But when it is considered that the ore is intimately associated with quartz, or rather with chert, this view of the origin of the ore does not appear admissible. It is difficult to conceive of a fused material so homogeneous as the substance which forms the matrix of the brec- cia, consisting exclusively of metallic sulphurets and silica. And even although it were possible to imagine a fused mass of this composition, the degree of heat required for its fusion would have been such as to exert an action on the adjoining limestone, simi- lar to that produced by certain igneous rocks, viz., a conversion of the greyish colored limestone into white crystalline marble. With regard to the second theory, the presence of sillica does not present any difficulty, because it is a well-known fact that that substance is deposited in large quantities from hot springs. It is not unreasonable to suppose that the water percolating through the rocks possessed a high temperature, because it is not unlikely that a higher temperature than the present prevailed after the Lower Silurian strata had been deposited. With regard to the manner in which the copper may have been dissolved, and held 464 Macfarlane on the Acton Copper Mine. in solution by tlie water, it seems evident that it could not have existed in the water in the state of sulphate of copper, from the oxydation of impregnated copper pyrites; because such a solution on coming in contact with limestone would have formed with it sulphate of lime and carbonate of copper. Nor is it possible to ignore the physical properties of copper pyrites, and suppose it to have been, to however slight an extent, soluble in water. The only solvents known for heavy metallic sulphurets, are the alka- line sulphurets. Many heavy metallic sulphurets when fused with sulphuret of potassium or sodium, yield when treated with water, solutions containing considerable quantities of the heavy metals ; and I have found that on fusing a regulus containing iron, copper, cobalt and nickel, with sulphate of soda and charcoal, and treat- ing the result with water, a dark green solution was obtained, containing, after careful filtration, all four of these metals. This solution, on exposure to the air, gradually oxydized, became color- less, and deposited the metallic sulphurets as a black powder. I am not quite prepared to assert that the copper in the veins above referred to was deposited in this manner ; but I am of opinion that if we are to adopt the theory of secretion from the side rock, this is the only explanation which is admissible. The third theory of the source of the copper is probably the correct one, and it is the one which is most in accordance with generally received opinions* Colta, for instance, regards it as certain that mineral veins proper have been filled up by infiltration, and that the material thus de- posited came from beneath.* If we however attempt to go a step beyond this general explanation, we must enquire as to the nature of the solvent, and in doing so can scarcely arrive at other results than those mentioned in connection with the second the- ory. We must regard the alkaline sulphurets as the most probable solvents under the circumstances ; and when we reflect that the sulphurets of platinum, gold, mercury, tin, tellurium, antimony, arsenic, vanadium, molybdenum, tungsten, nickel and iron, are all soluble in alkaline sulphurets, it will appear that the latter may have played a more important part in the formation of ore veins than has been hitherto supposed. When moreover it is remem- bered, how numerous and diverse the double sulphur salts are, and how many of these, especially arsenic and antimonious sulphurets • Cotta; Erzlagerstatten, p. 127. Macfarlane on the Acton Copper Mine, 465 occur in ore veins, the importance of the agency of tlie alkaline sulphurets in the filling up of such can scarcely be over-rated.* This sketch of the recent results of mining at Acton, would scarcely be complete without a description of the processes em- ployed for concentrating the ore, and a reference to certain experi- ments instituted for the purpose of ascertaining the amount of copper lost in the processes of crushing and jigging. As soon as the ore has been brought to the surface it undergoes the process of coarse spalling ; that is, it is separated from the waste rock, and broken into pieces having a diameter of from four to six inches. These pieces are sorted, according to the quantity of copper they contain, into first quality ore, second quality ore, crush ore and fourths. The first three sorts then undergo the pro- cess of fine spalling. The first quality ore is broken into pieces of the size of an egg^ and any poor rock which these may con- tain is picked out. It thus yields marketable first quality ore, containing from eighteen to twenty-four per cent. The second quality pieces, treated in the same way, yield marketable second quality ore, containing from ten to thirteen per cent. The Editofs note, by T. Sterrt Hunt, f, r. s. De Senarmont, in his researches on the artificial formation of the min- erals of metalliferous veins by the moist way, has shown that by the aid of heated solutions of alkaline sulphurets and bicarbonates, at tempera- tures of 200O and 300^ Centigrade, it is possible to obtain in a crys- talline form many of the native metals metallic sulphurets, and sulpharseniates, besides quartz, fluor spar and sulphate of barytes. These observations, and those of Daubree are cited by me in a paper in the Naturalist for December 1859, p. 500, with the remark that, in them, " we have, beyond a doubt, a key to the true theory of metalliferous veins.' ' Heated alkaline solutions (sulphurets and carbonates,) which are at the same time the agents of metamorphism, dissolve from the sediments the metallic elements which these contain disseminated, and subsequently deposit them, with quartz and the various spars, in the fissures of the rock." Mr. Macfarlane's view seems to be in perfect accordance with the theory which I have advanced. The notion that the contents of the rein have been deposited from springs coming from below, is in no way inconsistent with that of their secretion from the wall-rock, inas- much as we conceive that metalliferous and other mineral waters, in all cases, derive their soluble matters from certain permeable strata, and may afterwards either deposit these dissolved matters in the same strata, or more frequently rise to higher formations, where a lower temperature if more favorable to the precipitation of the dissolved elements. Oah. Nat. 30 Vol. VII. 466 Macfarlane on the Acton Copyer Mine, crush ore, after having been spalled down, and separated from the waste rock, assays from three to five per cent. It is further ti-eated by crushing and jigging. The so-called fourths consist of limestone containing copper pyrites in coarse grains, small strings and finely disseminated particles. This quality is not worked up at present. It is piled in separate heaps, in order to be treated by stamping and washing, so soon as the appa- ratus for that purpose is procured. Besides the coarser rock, there is produced, in the various workings, smalls, which consist of pieces of ore and rock whose diameter does not exceed three or four inches, and which are usually so coated with mud as not to be easily separable from each other. These smalls are first thrown upon a screen, the bars of which are one and a quarter inches apart; the larger pieces which remain upon it are sorted and spalled in the same way as the coarser rock ; while the smaller pieces, which pass through, and assay from two to three per cent, are at once sub- jected to crushing and jigging. The crush ore, and the finer part of the smalls, are reduced, by passing between cast iron rollers, to such a size as to pass through a sieve of twelve holes to a square inch. The crushed product is then brought into a jigging sieve, having sixty-four holes to a square inch. This sieve is wholly immersed in water, where it receives a succession of jerks, each of which causes it to descend, and suspends its contents in the water. These then arrange themselves according to their relative specific gravities ; the richest and largest particles at the bottom of the sieve, the poorest and smallest at the top. After the sieve has received a sufiicient number of jerks, it is raised out of the water, and the upper layer, or skimmings, scraped off". These contain from one and a-half to two per cent copper, and are thrown aside. That part which collects at the bottom of the sieve, and contains twelve to fourteen per cent of copper, is called ragging, and is a marketable product. There is sometimes produced au intermediate sort called seconds, occupying a position on the sieve between the skimmino-s and the ragging. This is laid apart, and afterwards re- jigged, the same products being produced as those above mentioned. In this process of jigging a considerable portion, the finest part of the crush work, falls through the sieve into the box below, which contains the water, and is called hutch-work. This, on being washed in a streak from the slime which it contains, assays from Macfarlane on the Acton Copper Mine, 467 eight to eleven per cent, and is then in a marketable state. The costs of these various dressing operations were as follows : — Coarse spalling costs from fifteen to twenty-five cents per cubic yard of rock, according as the same contains less or more ore ; fine spalling from fifty to eighty cents per ton of the resulting ore, according to the quality of the rock operated on. The processes of crushing and jigging cost during January, February and March, 1682, $5.60 per ton of products, and 81.15 per ton of crush ore. The total expense of coarse and fine spalling, and crushing and jigging, per ton, of all the products is at present $5.25. The crushing and jigging processes are ulmost the same as those adopted in Cornwall for the dressing of crush ore, ;^et they are attended with the loss of much of the copper contained in the original crush ore. Having for a long time estimated the quantities, and assayed the samples of the crush ore put through the rollers; and ascertained the weight and contents of the resul- ting products, I have found that the loss of copper is much more than might at first sight be imagined. I subjoin a few of the results obtained: From the I'Zth of November to the 12th of December, 1861, there were crushed 956,760 lbs. of ore, contain- ing 4.6 per cent, or 44,010 lbs. copper. From this there were produced 283,451 lbs. of products, averaging 10.95 per cent, and containing 31,052 lbs. copper. There were consequently lost 673,309 lbs. of skimmings and slimes of 1.92 per cent, con- taining 12,958 lbs. copper. Thus 29.5 per cent of the copper contained in the crush ore was lost in the skimminofs and slimes. Further, during January, February and March, 1862, there were crushed 2,881,100 lbs. of ore averaging 3.4 per cent, and containing 100,303 lbs. of copper; from which there were roduced 615,520 lbs. of products averaging 9.5 per cent, and containing 58,711 lbs. of copper. There were con- sequently 2,265,580 lbs. of skimmings and slimes of 1.83 per cent* containing 41,592 lbs. of copper. Thus 41.5 per cent, of the copper contained in the crush ore was lost. It is to be remarked? however, with regard to the foregoing results, that much of the copper contained in these skimmings and slimes is with proper appliances recoverable. Subsequent to the first of July, 1862, ar- rangements were made for dressing the ore by contract, and for working up a part of the slimes as these were being produced. Under this system the following result was obtained : — During 468 Macfarlane on the Acton Coj^fper Mine. the months of July, August and September, 1862, there were crushed 3,348,887 lbs. of crush ore and smalls, of from 2.0 to 5.9 per cent, averaging 4.1, and containing in all 13*7,969 lbs. of cop- per. From this there were produced 1,073,644 lbs. of products of from 8.0 to 12.6 per cent., averaging 9.9 per cent, and con- taining 106,625 lbs. of copper. There were consequently cast aside 2,275,243 lbs. of skimmings and slimes, averaging 1.38 per cent, and containing 31,344 lbs. of copper; which is equal to 22.7 per cent of the copper contained in the original ore. From the results here narrated, it would appear that at least one-fourth of the copper contained in the crush ore is lost in the process of dressing it. The actual value thus wasted goes far to counterbalance the saving of freight which results from concen- trating the ore. It would not certainly be attended with greater advantage to send the crush ore of four or five per cent to market instead of dressing it ; but it admits of plain proof, that it would be better at once to sell an ore of seven per cent, and pay freight on it to Boston or New York, rather than to submit it to further concentration by crushing and jigging, and sustain the great loss of copper which occurs in these operations. The following calcu- lations will be found to confirm this statement : 100 tons of 7.0 per cent ore would bring in Boston $4.00 per unit ; which for 6.5 per cent, (^ per cent being deducted for the difference between dry and humid assay) is equal to $26.00 per ton, $2600.00 From this deduct freight, barrels, &c., at $9.00 per ton, $900.00 There remains, $1700.00 On the other hand, 100 tons of 7.0 per cent ore would yield, by crushing and jigging, about 43f tons of 12.0 per cent products ; which would bring, say at $4.30 per unit, for 11.5 per cent, $49.50 per ton,. . . $2163.43 From this deduct : Cost of crushing, &c., at $5.50 per ton, $240.70 Freight and barrels, at $9.00 " 393.75 634.45 There remains, $1528.98 or $1.71 per ton less than when at otice sent to market. It is thus evident that an advantageous concentration of a seven per cent ore by means of crushing and jigging, is not possible. The Macfarlane on the Acton Copper Mine. 469 question next arises, as to whether such an ore could not be smelted at the mines, and a large part of the cost for freight and barrels saved : — 100 tons of this ore might, by smelting, be made to yield 16f tons of regulus of 36.0 per cent (even sup- posing that one-seventh of the copper were lost in the operation). This would be worth, at 84.50 per unit, or $162 per ton, 82700.00 From which deduct : Cost of smelting, at 85.00 per ton, ..... 8500.00 Barrels and freight, 89.00 " 150.00 650.00 There remains, 82050.00 The 100 tons of 7.0 per cent ore sent to market, would have yielded, according to the previous calculation,. . 1700.00 Consequent profit by smelting 8350.00 or 83.50 per ton of seven per cent ore. It would thus appear that the best mode of treating the crush ore would be to separate from it as much seven per cent ore as possible, and to treat the refuse from this, which might assay two per cent, by stamping and washing. Of this two per cent ore, the fourths (now set aside) would, on being worked up, yield a large quantity ; and although they might be unable to bear much of the mining expenses, would considerably more than pay the cost of their own concentration. In order to ascertain the fitness of some of the products for metallurgical treatment, the following examinations were made towards the close of last year. A sample of first quality ore from No. 4 shaft gave, Silica 25.12 Carbonate of lime 33.10 Iron 5.81 Copper 24.75 Sulphur, 11.22 by diflerence. 100.00 470 Macfarlane on the Aeton Copper Mine, A sample of ragging gave : — Silicious matter 16.92 Carbonate of lime 53. 0*7 Carbonate of magnesia ..•••• . . trace Iron 4.06 Copper 13.07 Sulphur 11.62 by difference* 100.00. A sample of butch-work gave : — Silicious matter 24.32 Carbonate of lime 53.10 Carbonate of magnesia 2.10 Iron. 3.36 Copper 9.95 Sulphur 7.17 by difference. 100.00 From these results, and from others previously given, it will ap- pear that silica and lime are almost the only slag-producing ma- terials contamed in these ores. Iron is present in small quantity, but without previous calcining, which in this case is inadmissible, it would go to the formation of the regulus. The compounds of silica with lime are all but infusible ; but these substances form with iron oxide, easily fusible slags, which are frequently produced iu copper-smelting works. In smelting the Acton ores, therefore, a flux containing iron oxide, such as puddling slag, or roasted iron pyrites, is indispensable. The cost of these would not add very materially to the expense of smelting ; but it would of course be better, if such could be had in the neighborhood, to use in place of these fluxes, poor pyritous copper ores, previously calcined. The total product of the Acton Mine during the period to which this paper has reference, viz., from September 1st, 1861, to September 30th, 1862, was 2336 tons of 2,352 lbs. ; or 2,747 tons of 2,000 lbs, the average copper contents of which amounted to 12.0 per cent. This is equal to an average monthly production of 179 tons of ore of 2,352 lbs., or 211 tons of 2,000 lbs. In reality, however, the production was much greater in the summer than the Macfarlane on the Acton Cojyper Mine, 471 winter months. For instance, the total produce during July, August and September last, was, — 366if|i tons first quality ore. mm " second " " 150^¥ft " ragging 312|Ht " hutch- work sVsVj " buddle-work 994|f If tons in all, or 331 tons monthly. With regard to the future of the mine, I see no reason to doubt that it will be as successful as its past; provided always that a due amount of prospective work is done, and that arrange- meuts are made for saving freight, and increasmg the value of the poorer ores, by smelting the products of the mine on the spot. To this must of course be added prudent and economical manage- ment, without which even the richest mines yield little profit. In conclusion, I have to remark, that it may seem to some, that in the foregoing, I have been unnecessarily minute. I have, how- ever, thought myself justified ingoing into detail, by the altogether exceptional character of the deposit. As far as I am aware, there is no instance known of a mineral deposit bearing even a moderate resemblance, in its various relations and characters, to that of the Acton Mine ; and, consequently, it is impossible to draw on any stock of experience gained elsewhere, for guidance in exploring it. That the future of the mine may be successful, and its permanency established, no fact, however seemingly trivial, observed in its ear- lier working ought to be regarded as unimportant. That other deposits of a similar nature may yet be discovered in the district is not impossible ; and in the working of such, the experience gained at Acton may not be altogether valueless. For these reasons I have, in the foregoing paper, mentioned details and minutite, which few may find useful ; but at the same time I trust there will be found in it matter of more general interest. Actonvale, Canada East, 28th October, 1862. 472 Miscellaneous, MISCELLANEOUS. ON THE AGE OF THE PYRAMIDS OF EGYPT. Mahmoud Bey, astronomer to the Vice-roy of Egypt, has just published the results of his investigations of the pyramids, under- taken at the request of the Vice-roy. The measures of the great pyramid he finds to be 231 meters for the sides of the square base, and 146.5 meters for the height; so that the faces form an angle of 54° 45' with the horizon. This agrees with the known inclinations of the six other pyramids of Memphis ; which vary be- tween 51° and 53°, and average 52° 30'. This common inclina- tion ; and the fact that the pyramids, and the other funereal monu- ments which surround them, are, as Mahmoud has satisfied him- self, always placed exactly facing the four cardinal points, suggests that these pyramids had some relation to a celestial phenomenon, and to the divinity which presided over that in the Egyptian my- thology. Now he has found that Sirius, when it passes the me- ridian of Gizeh, shines vertically upon the southern face of the pyramids ; and in calculating the change in the position of this star for a series of centuries, shows that 3,300 years before the Christian era, the rays of this star, at its culmination, must have been directly perpendicular to the southern face of the pyramids, inclined at an angle of 52° 45' with the northern horizon. Ac- cording to the principles of astrology the influences of a star are greatest when its rays fall perpendicularly upon an object. If now we suppose that these pyramids were constructed a little more than 5,000 years ago, it would appear evident that their faces received the angle of 52 degrees, in order to be perpendicu- lar to the rays of Sirius, the brightest star of our northern heaven ; which was consecrated to the god Sothis, the celestial dog, and the judge of the dead, and was also said to be the soul of this deity. This opinion is confirmed in an unexpected manner by the fol- lowing considerations. The pyramids, being tombs or funereal monuments, would naturally be under the patronage of that divin- ity who presides more particularly over the" dead, that is to say with Sothis, who is no other than the thrice-great Hermes, Cyno- cephalus, Thoth or Anubis. Now the hieroglyphic designation of Sothis is a pyramid by the side of a star and a crescent. Nothing is therefore more natural than this relation thus discovered by Mahmoud Bey between Sirius and the pyramids. The date of Miscellaneous. 473 3,300 B. C, thus assigned to these structures, accords with Bun" sen's determination, according to which king Cheops reigned in the thirty-fourth century before our era. It also agrees with the tradition of the Arabs, according to which they were constructed three or four centuries before the deluge ; which they assign to the year 3,716 before the Hegira. — {Le Cosmos, JVov.21st, 1862.)

Father Secchi, the learned director of the Roman As- tronomical Observatory, has just published an essay, in which he discusses from an advanced point ' >f view the theory of attraction After having shown, in accordance with the views so ably ex- pounded by Mr. Tyndal in his paper on Force, published in the Naturalist, (p. 241,) that all the physical forces or movements of which we are cognizant come to us from the solar centre, the learned Jesuit inquires, " But how does this movement or se- ries of movements return to the sun ? Who knows but what that part of the heat thus emanating from the sun, which is not lost by radiation into space, is converted into an impulsion of the mass of the earth towards the sun ? I do not pretend to give a theory, but only to propose a conjecture, which it will be suffi- cient for me to show not to be absurd." " We see that the intensity of heat, like that of gravity, dimi- nishes inversely as the square of the distance. We know also that a prodigious quantity of molecular movements come from the sun by luminous and calorific radiation, and under the form of vibratory disturbances, remain, apparently destroyed, at the earth's surface, instead of being lost by radiation towards the planetary spaces. In fact, heat coming from sources of a very high temperature (that is to say, heat of short undulations,) when brought to a lower temperature, (or to long undulations,) can no longer traverse the terrestrial atmosphere and radiate into space. A certain quantity of motion coming from the sun must thus rest imprisoned in terrestrial bodies, by the chemical force to which it gives rise. So that in reality the vis viva, and the quantity of move- ment in the terrestrial globe, and its surrounding mass of ether, must increase indefinitely, if there were not some way of escape or discharge. Why may not this discharge be the incessant fall of the earth towards the sun, a fall expressed by the linear dis- 474 Review, tance which the earth deviates from the tangent of its orbit ; which tangent the earth would follow, in virtue of its inertia, did not some cause draw it towards the solar centre ?" Of this brilliant and novel conjecture, the learned editor of Le Cosmos, from whom we extract the above, remarks, that it seems to be one of those happy inspirations which belong to truth alone ; and he adds, " there is great merit in having originated an idea which has never before presented itself to the human intelligence and which, in time to come, may bring forth fruitful results." — Le Cosmos, Nov. 21, 1862. t. s. h. REVIEW. DANA'S MANUAL OF GEOLOGY.* In no part of the world has the science of geology been more successfully cultivated than in North America. But the results that have been arrived at, are scattered through a multitude of reports of the different surveys, and papers of greater or less length in the scientific journals. Up to the present time he who has endeavored to get a clear idea of the geology of the whole North American continent has found it necessary to devote more time and means to the object, than most students can well afford. In the important work, just issued by Professor Dana, this great difficulty is removed. We have now in one compact and beauti- fully illustrated book, not only a comprehensive and well-balanced account of the elementary principles of the science, but also the general results of what has been ascertained of the geology of this continent, down to the present moment. We have not, just now, leisure to give a full review of this excellent publication, and must therefore content ourselves with a mere glance at its contents. Prof. Dana has divided his subject into four parts, as follows. — 1. Physiographic Geology. — In this part of the work, are described the forms of the earth's surface, as exhibited in the * Manual of Geology : treating of the principles of the science with special reference to American Geological History, for the use of Col- leges, Academies, and Schools of Science. By James D. Dana, M. A., LL. D., Silliman Professor of Geology and Natural History in Yale College, &c., &c. Hlustratedby a chart of the world, and over one thousand figures, mostly from American sources. Philadelphia: pub- lished by Theodore Bliss & Co. London: Triibner & Co. 1863. Small 8vo, pp. 812. Review. 475 distribution of the land and water ; the directions of certain physiographic lines, in conformity with which the boundaries of the continents, the ranges of islands and chains of mountains are arranoed ; the system in the rehefs or surface-forms of the con- tinental lands ; the system of oceanic and atmospheric currents' and the general laws of the distribution of forests, prairies and deserts. All these phenomena are within the domain of physical geography, but they can never be well understood unless investi- gated through geology, as their origin dates far back in time. 2. LitholoctICal Geology. — Relating to the composition and different kinds of rocks. 3. Historical Geology. — Under this title is discussed the main portion of the subject; the description in their order, of all the formations from the most ancient up to the most recent. Here we have, for the first time, the science of geology elucidated by spe- cial reference to the series of American rocks ; thus removing the great diificulty we have pointed out in the first lines of this notice. Full details of all the deposits, their lithological composition, their characteristic organic remains and geographical distribution are given. There appear to be about YOO figures of fossils, nearly all of which were drawn on wood by Mr. F. B. Meek, an accom- plished artist, and one of the best palaeontologists of the continent. Most of the species figured are American, and several of them are from the Decades of the Canadian Survey, representing peculiar forms only possessed by the Provincial Collection of Canada. It is not uncommon to find works on general geology illustrated bv figures, which, for all natural-history purposes, are perfectly worth- less. This must happen when neither the artist nor the author is a naturalist. In the book before us, the illustrations are first-class for the reason that all the parties engaged in their production, per- fectly understood how to prepare them. 4. Dynamical Geology. — This division treats of the causes of even sin the earth's geological progress. " These events include the formation of all rocks, stratified and unstratified, with what- ever they contain, from the earhest Azoic to the modern beds of gravel, sand, clays, and lavas; the oscillations o' the earth's crust ; the increase of dry land, elevation of mountains, and elimi- nation of the surface features of the globe ; the changes of climate • the changes of life." The work concludes with an appendix and a copious index. Geology is a science of such vast extent, and so largely com 476 Retici posed of all others, that few m^ the almost universal knowledge required to produce a .laal of its elementary principles. The author of this wui oeing a profound geoloo^ist mineralogist, zoologist, and physicisU one of the best qualified for the tasL Ills book is a great en, and its publication will mark the commencement of a new ;a in the progress of the science. In conclusion we would st nglj recommend it to the Canadian student. With the Gener. lie port on the Geology of Canada, soon to be published by Sir \ E. Logan, the Decades o^ the Survey, and Dana's Manual, be ci enter the field unimpeded by the crowd of diflBculties to whicl observers in this province, have heretofore found themselves op)Hed at the very outset E.
