AlleFs Notes on the Characeae. While much attention has been given by Geologists to the deposits of the early and middle part of the Quaternary period in North- Eastern America, there is a part of this great cycle of time about which we have yet a great deal to learn, and which is of especial interest as forming the connecting link between Quaternary and Recent Time. The interest fell in this part of the geological record is enhanced by the fact that the deposits yield the earliest traces of man — for it is probably to this period that the gravels of Trenton, New Jersey, containing the rude stone implements of a primitive race belong. The Boulder clay and Leda clay which were formed in Quaternary times have been closely investigated, and much is known of the animals which inhabited the seas and shores of North-Eastern America in the Leda clay or C-hamplain epoch. Even the vegetation of the land can be described in a general way with con- siderable accuracy, but of the succeeding Terrace epoch the biological history is very imperfectly known. The deposits of the Torryburn Valley, five miles N. E. of Saint John, supply an important link in this part of the geological chain ; and the period in the Terrace epoch 4 Bulletin of the Natural History Society. when this valley was elevated above the sea and occupied by fresh- water lakes, can be indicated with considerable exactness. The time when the Torryburn deposits began may be arrived at from the following considerations : The raised beaches and sand flats of the Terrace period in this region, which are of Quaternary age and form the connecting link with the Torryburn deposits, contain but few mementoes of the Life of those times. The “ Saxicava sands” of the St. Lawrence Valley which were formed in the Terrace epoch, and were once sand flats along the sides of that valley, are characterized by the remains of the sea shells, Saxicava rugosa ( arctica ), and Tellina ( Macoma J yroenlandica; but in the corresponding deposit near Saint John the former of these shells is to a great extent replaced by the Common clam ( Mya a,renaria)^ so that it becomes a “ Mya” or “ Macoma” rather than a “ Saxicava sand.” Such deposits of the Terrace period can be traced down to the present sea level, and there are indications that they extend many fathoms below that line. From this we infer that the sea at the close of the Terrace period had withdrawn far from the present shore line and that the latest Terrace deposits are now con- cealed from our view, by tlie return of the sea to its present level along the coast. During the time when these changes of land and sea were going on, the fresh-water deposit of the Torryburn Valley was accumulating. It may be said, therefore, that the Champlain epoch had passed away and the Terrace period was considerably advanced when the first fresh-water beds were formed in the Torry- burn lakes. In this part of Canada the Champlain or Leda clay was deposited in ai sea which stood about 200 feet above the present sea level ; and in that part of the succeeding Terrace period when the divide of the Torryburn Valley was exposed by the rising of the land, the sea had shoaled so far as to bring the land up to within 65 feet of its present level. Two important shore lines marked by terraces, had already been raised above the water when the Torry- burn lakes first appeared, and two others of equal importance mark the slopes along the sea-shore, below the level of the summit of Torryburn Valley; the 65 feet level may therefore be considered as liolding a middle place in the Terrace epoch, if we suppose that epoch to begin when the higher part of the Leda clay was a-wash at the sea-level. But if the beginning of the Terrace period be Lacustrine Formation of Torryburn Valley. 5 reckoned from the time when the latest of the Sax icava or Macoma sands* began to be deposited on the Leda clay at the present sea level, then the first of the Torryburn fresh-water deposits must be relegated to the latter part of the Champlain epoch. It seems, however, more correct to regard the Terrace period as overlapping the Champlain, and therefore to consider the local deposits of Torryburn Valley as beginning in the middle of the Terrace period. In the Torryburn Valley there are three depressions which were once occupied by ponds of water. Of these hollows, the southern one was shallow and was soon silted up; another, the eastern, was through the greater part of the Recent period occupied by a shallow lakelet, but finally became dry. The third or central depression of the valley was much deeper than the others ; it still holds the reduced waters of a lake, which once rose to its rocky brim, and is known as Lawlor’s Lake. The geology and physical history of these basins is of much interest in connection with the fresh-water deposits, and will be described in a future article, but the following observations are confined to a description of the fresh-water deposits only. In the process of building the E. & N. A. (now the Intercolonial) Railway, a heavy rock-cutting was made at the Western end of Lawlor’s Lake, and about 13 feet in depth of its waters were drawn off. By this means the beds of shell-marl which underlie the waters of the lake were exposed to view, and attracted the attention of certain members of this society. Samples of the marl containing fresh- water shells were sent to the museum of Comparative Zoology at Cambridge, and the peculiar varieties of a species of Valvata occurring in them, attracted the attention of Prof. Alpheus Hyatt of Bos- ton, who visited the Lake in 1877 for the purpose of examining the marl. At his request I undertook to study the geology of the deposit, in connection with his proposed work on the biology of the mollusca which inhabit its waters and are found in the marl beds. To investigate certain doubtful points which had come up, I found it necessary to make more careful examinations than I at first contemplated, and in the summer of 1880 and 1881, made collec- * Macoma groenlandica is a small, lenticular, bivalve mollusc about the size of the human thumb-nail, a variety of which, Macoma fusca, is now quite plentiful along the sandy beaches of the Bay of Fundy. 2 6 Dtilletin of the Natural History Society. tions of material from the base to the summit of the lacustrine deposit. These collections which exhibit the whole series of layers in the deposit, from the Saxicava or Macoma sand upward, have since been examined in a general way, and a synopsis of the results obtained, in so far as they relate to the Land vegetation, and the fresh-water plants of the order Characeae^ are given in the following pages, together with valuable notes on the Characese from the pen of Dr. T. F. Allen of New York, a celebrated writer on these low forms of vegetable life. As the investigation of the deposit of the lake is not yet com- pleted, I shall only give at present a brief outline of the physical aspect of the formation, chiefly to elucidate Dr. Allen’s notes on the Characere. Before my examination of the lake deposit it was not suspected that any lacustrine beds other than the marls existed there, the underlying clays being supposed to be marine ; but it was found that the pure shell-marl formed relatively less than a half of the whole lacustrine deposit, where it is accessible along the present margin of the lake. Several pits were sunk through the fresh-water deposit, and the most complete series of beds observed is that given in the following section. The numbers indicate groups of beds which have a common physical aspect, and the letters a thickness in each case, with a few exceptions, of about 3 inches of the deposit.

Hameri and Mytilus edidis, common in the Upper Leda-clay but which are also found in tlie marine beds immediately beneath the lacustrine clay of Lawlor’s Lake. The passage from the marine to the fresh-water part of the clays, though not obvious to the eye, can be detected by a change in the s})ecific gravity of the clay, and this will be found to be a useful method of separating the different parts of a continuous deposit, partly of salt-water and partly of fresh- water origin. At 16 the clay is about 1-10 lighter* than the marine clay beneath, and in the next inch No, 2a is reduced so as to be only two thirds of the weight of la. This change of density in the clay is due to the introduction of organic matter, chiefly low forms of vegetation which must have grown abundantly in the lake after the exclusion of the sea. The vegetable matter is mostly cellular tissue and not readily noticed except for the changed color of the clay ; but its effect upon the weight of the clay can be at once seen by comparing the speciflc gravities, of Nos. 3 and 4, which are reddish clays like No. 16, with that of the marine bed No. la which is only about a flfth heavier than these (Nos. 3 and 4.) The large addition of vegetable matter in No. 5, by which the color of the clay has been changed to olive grey, has a decided effect on the specific gravity ; in the lower part of this division the weight is one quarter less than the standard of the marine clays, and in the upper part is not more than half. These weights do not express the full difference in the actual weight (less the water) of these different parts of the deposit when fresh ; for in drying No. 5 lost nearly one quarter of its bulk, and No. 2 also lost in volume considerably. The shrinkage is no doubt due to the large quantity of cellular algae which these deposits contain. Such a marked difference between the weight of marine and lacustrine clays in the successive, or alternating beds of a deposit, is not to be looked for in larger basins, but I have no doubt the rule will be found to hold good to an appreciable degree in almost any fresh-water deposit formed in a basin of moderate dimensions. Div. 5 marks an important epoch in the history of the lake, for at this period the influx of clay carried down by streams into the lake was arrested, and the molluscan fresh-water fauna., of which ♦The weights given are those of air-dried samples of the deposit coarsely pulverized. 8 Bulletin of the Natural History Society. only the faintest traces can be found in the clay beds, immediately spread and occupied the waters of the lake. It is an interesting subject of inquiry as to what caused this sudden and important change in the condition of the lake and of the surrounding slopes. The period during which the lacustrine clays were deposited was one of rapid and momentous change in the fauna and flora of the lake, being marked by the arrival and increase, and on the other hand by the curtailment in numbers and probably the extinction of species in quick succession. The part of the deposit above the peat, in the accumulation of which a much longer period of time was taken than was required for the clays, marks on the contrary a quiescent period and was characterized by a slow and gradual change in the fauna and flora. One cause which may have had an important influence upon the deposits made during the period of the Lacustrine clay, was the condition of the surface of the land when Torryburn Yalley emerged from the sea. The formation of terraces at various levels along the sea-coast in this region during the Saxicava period shews that the rise of the land from beneath the ocean at this time was not slow and gradual, but was effected by spasmodic movements which at once, or in a very short space of time, carried large areas of surface above the sea. Such a movement between the time of the forma- tion of the 100 and of the 50 feet terrace would have exposed the steep hill-sides around Lawlor’s Lake, at that time covered with marine clay, to the action of atmospheric agents ; there was no mat of vegetation, nor covering of trees to absorb and retain moisture, and the effect of rains and spring floods in sweeping a turbid deposit into the lake can be readily understood. But the sudden cessation of this mechanical deposit at No. 5 and its subsequent entire exclusion from the lake is not so easily explained. Possibly an improvement in the climate may have been influential in promoting a more rapid growth of vegetation and in moderating the spring floods — possibly artificial dams made on the stream which enters the lake may have arrested the muddy waters in their course, and prevented them from entering the lake until deprived of the clay which they carried in suspension. It would appear that the growth of the fresh-water plants was subject to much vicissitude during the time when clayey sediment was Lacustrine Formation of Tomyburn V alley. 9 pouring into the lake ; but as soon as this ceased, these plants immediately took full possession of the lake in advance of the arrival of the molluscan fauna, and even after this addition to the living forms which peopled the lake, the lacustrine vegetation formed a predominating element in the deposit made at its bottom. After the arrival of the mollusca, however, the species of plants were not all the same as those which lived in the lake before that time, but included forms better suited to the clear, calcareous waters in which the water-snails delighted. Such plants, too, as were now in the lake had a better hold of their habitat, flourished in great numbers, and the species were not replaced with the same rapidity as their predecessors had been. OBSERVATIONS ON THE CHARACE^. The Charm participated in the conditions eftecting other portions of the lacustrine vegetation, and their appearance in the lake at a very early period is noticable and somewhat remarkable. These plants are of a comparatively low order, and entirely aquatic in habit. They live submerged in the water, their seeds are not adapted for being wafted by the wind, and the disagreeable odour, which characterizes the living plant, would repel many animals, which are active in pro- pagating other plants, by transporting their seeds from place to place ; yet a species of this genus was one of the earliest migrants into the lake. The permanency of Chara when it has once taken possession of a sheet of water may be inferred from the fact that difierent species flourish in lakes in the same neighborhood without intermixture for (historically) long periods of time — a lake having one or more species or varieties peculiar to itself. The early advent of Chara at Lawlor’s Lake is therefore somewhat remarkable. It is true that some species of this genus inhabit brackish water ; but the relations of Lawlor’s Lake to the surrounding land show that at its emergence from the sea, the transition from salt to fresh water conditions must have been rapid, if not instantaneous. Though the stems and leaves of Chara are perishable, the small nucleus or spores, which are about the size of a minute pin-head, are hard and durable ; and owing to the spiral strim or keels (due to the impression of the spiral tubes of the sporangia or seed vessel) with I o Bulletin of the Natural History Society. which they are ornamented, are very striking objects under the microscope. In the fossil condition these seeds are generally black, with a smooth shining surface, and the keels are usually coated with shining white crystals of calcareous salts. In the washings of the marl and clay beds these minute seeds float to the sides of the vessel and may be removed in great numbers. The seeds or spores though comparatively scarce in the low*er divisions of the deposit, become very numerous in Div. No. 6, and in Nos. 7, 8 and 9 they are found in enormous numbers. They appear to be most numerous in the middle portion of Nos. 7 and 8, respectively, and in the upper part of No. 9. The species are distinguished by the form and size of the spores, the number and distinctness of the stride or keels, &c. Dr. Allen finds the spores of one species, which he identifies with Chara coronata^ Ziz., as low down as the lower half of No. \h — the very beginning of the fresh-water clay. This species I found to increase in number in the upper part of No. 1, and the lower part of No. 2, but in the upper 'two thirds of No. 2, and in the lower half of No. 3, it appears to be scarce, as none were observed. It reappears in considerable numbers in No. 4 and the lower third of No. 5. This is the limit of the clayey sediment in the deposit, and I did not detect it higher up. Dr. Allen, however, found examples of what he considers the same species, “ though sparingly,” in the higher numbers, 6, 7, 8 and 9. The species has left its remains most abundantly in the lacustrine clay, and they are especially numerous in those parts of the clay beds which are most heavily charged with mineral matter of sedimentary origin. Its abundance in these beds would seem to indicate that the species is partial to waters contain- ing an abundance of argillaceous sediment. In the accompanying wood cuts the first four figures, copied from drawings by Dr. Allen? represent examples of this form of nucleus, arranged from left to right as they are found at successively higher levels in the deposit : the two last figures of the second row represent irregular forms, or varieties of the same species. Another species which Dr. Allen detected in samples from the lower part of the lacustrine deposit is of small size, nearly globular, and has from 6 to 7 keels. This nucleus was found in the lower part of 26 and of 36 ; also in 4a and in 66, &c. Its range was therefore much the same as that of the last named species.

Lacustrine Formation of Torryburn Valley. i 3 Allen says that this seed may belong to a Nitella^ perhaps N. megacarpa Allen, as he knows of no Chara with similar nuclei. The third row of figures, and the first two figures of the fourth row, represent this species as drawn by Dr. Allen, and the forms are arranged in ascending geological order from left to right, the oldest being to the left in the third row. The great bulk of the seeds of Chara found in the deposit belong to a species which exhibits considerable diversity in the form and markings of the nucleus. I did not find any form of this type lower down than the top of No. 25 ; but Dr. Allen has detected it in the upper part of 2a and the middle of 25. It would, therefore, appear to be limited in the lacustrine clay, to that part which is least charged with mineral matter, and even there it is very scarce. It seems to have found difliculty in maintaining itself in a habitat where C. coronata flourished ; but later in the history of the lake, when the clayey sediment disappeared, it became immensely abun- dant. The partiality of this species for clear water is very evident in its increase and prevalence in the higher part of the lake deposit. When G . coronata disappeared from the lower layers of the Lake Peat, No. 5, this species immediately took its place, and at the top layers of the peat its seeds had become numerous. In No. 6 the seeds are quite common, and its prevalence in the lake seems to have been accelerated rather than retarded by the spread of the Molluscan fauna. This form of nucleus was long-elliptical-oblong i with sharp keels or striae, generally about 12 in number, but varying j from 10 to 13 in those preserved in the deposit above the Peat ^ (No. 5), though perhaps with more numerous ribs on the spores I from the Lacustrine clay (No. 2, &c.). This nucleus, according to Dr. Allen, has the character of C. fragilis Desv. Nos. 12 to 16 and No. 17 (end view) are the principal varieties of this form, and are arranged in ascending order from left to right; Nos. 18 and 19 ! are somewhat irregular forms of the same species. Dr. Allen recognizes two other types of spores, one of which is broadly oval and with ribs less prominent than those of the C. fragilis form ; this occurs in No. 7c, &c., and has the characters ; oiC. intermedia A. Br., a species now living in the lake. This form is figured in the last row on the wood cut. The other type of spore referred to above is figured beside it, and is smooth, long-oval and 14 . j i Bulletin of the Natural History Society. has faint, spiral striae or ribs. This Dr. Allen has not deter- mined, but thinks it may be a variety of the last named species. ! DR. T. F. ALLEN’s NOTES ON THE CHARACE.F OF LAWLOR’S LAKE. “In Xo. 16 are found the seeds of a Chara which with variations occur in most of the numbers, though sparingly in the higher numbers (7, 8 and 9). This form has seven prominent angles, varying to 6 and 8. Its length varies from 48026 to 63426, and its breadth from 408 to 48826. The accompanying drawings magnified 50 diameters represent this form, (Figures Xo. 1 to 6.) In Xos. 26l, 361, 4a and 66 and c. is a small globular form, quite distinct ; angles usually six varying to 5 and 7, prominent ; length 340 to 36526 breadth 315 to 34026 * slightly longer than broad (Figures Xo. 7 to 11.) From 2(T6 up through all the numbers is found a large, variable, but definite form. The striae are numerous, from 11 to 14 in num- ber, the angles prominent, sharp. Length 536 to 55026, breadth 390 to 512i6. Quite variable in form and size, but we have found it impossible to distinguish definite characters, owing to the innu- merable intermediate forms. The most pronounced forms are given in Figures 12 to 20. There is a form found now and then, especially in Xo. 6, with very faint striae, but in other respects similar to the preceeding. This form is given in Figures 21 and 22. The recent Chara from the adjacent pond (Lawlor’s Lake) belongs to the species Chara intermedia, A. Br., probably to variety Ameri- cana, A. Br., but as it is immature (in the sample sent) the seeds cannot be inspected. • Note 1. — The first mentioned species belongs, doubtless, to a form or forms of Chara coronata Ziz. This species is exceedingly varia- ble in size and general appearance ; the seeds found in these deposits approach closely to our common form, known as variety Schweinitzia, but the angles are much more prominent and sharp, and its outline and general appearance differ considerably. (Figs. 1 — 6). Note 2. — The small globular seeds may belong to a Nitella; we know of no Chara with similar nuclei. The species cannot be determined, though from the character of the nuclei we might infer Lacustrine Formation of Torryburn V alley. 1 5 their belonging to a species not unconmioii in that region (North- Eastern North America), N. megacarjya, Allen, (Eigs. 7 — 11). Xote 3. — The lai'ge black seeds may be classed in three groups, the long and rather narrow, with sharp angles, (Figs. 12 — 18), the broadly oval (Figs 19 and 20), and the oblong with very faint striae (Figs. 21 and 22). The first group has the characters of C.fragilis’ Desv. ; the second of C. intermedia^ A. Br. (now living in the lake), and the third cannot be determined accurately ; possibly it may be a form of the latter class. Note 4. — We do not discover any progressive change of form in the nuclei from diflferent numbers (or divisions of the lacustrine deposit), nor any characters which would lead us to suppose any of the nuclei to belong to extinct species. The first form {C. coronata. probably) has no exact counterpart among our existing species, but they are not well known.” NOTES ON THE LAND FLORA AND FAUNA. Scattered through the various members of the lake deposit, but more particularly abundant in the Clay, are fragments of wood, bark, cones of evergreen trees, bud-scales and leaves, and fruits of several species of Land plants. Among the earliest determinable objects of this kind are the leaves of the American Fir [Abies hal- samea): these leaves were not found plentifully, and are smaller than the average of leaves of the firs now living in the neighborhood. This species was not found so low down in the deposits of Lawlor’s Lake as in those of the Eastern Basin. The seeds of the European Cranberry (the small marsh cranberry) {Vaccinium oxycoccus), has a wide range through the deposits of Lawlor’s Lake, but is less plentiful in those of the Eastern Basin. It was very plentiful throughout the layers of Div. 2, having first appeared in Division No, 1. Throughout Nos. 3, 4 and 5, it is also found, but above this becomes scarce. The appearance of this species among the first in the lake deposit is quite in accordance with Nature’s provisions for its propagation, — namely : the tough, impervious skin of the fruit, the floating air-cells of the pulp, the hard nut-like covering of the embryo, tkc. In the Eastern Basin the remains of the Black Spruce {Abies nigra.) were found at a lower level than in the deposits of Lawlor’s I 1 6 Bidletin of the Natural History Society. Lake, having been observed in Div. 2, but the numerous twigs and branches of soft-wood trees buried in the Lacustrine clay at this horizon are probably in part of this species. The leaves were smaller than the average of those of living trees. The Larch {Larix Americana) was also first detected in the Eastern Basin, but occurs at a higher level in the Lake deposit. In their slenderness, and the close approximation of the nodes to which the leaves were attached, the twigs resemble those of trees that grow in bogs, or wet land with a cold northern aspect. The Sweet Gale [Myrica Gale), a bush with leaves that yield a balsamic odor when crushed, was plentiful around the borders of the Eastern Basin when the beds of No. 5 were deposited in the Lake. In the Eastern Basin at the horizon of No. 6 of Lawlor’s Lake deposits, cones of the White Cedar [Thuja occidentalis) were first observed — and the same basin at No. 7, contained remains of the Yellow Bii'ch [Betula lutea), — a species of Willow and a number of species of deciduous shrubs and trees, including Birch, Alder and other kinds, still undetermined, grew around the Eastern Basin, or at Lawlor’s Lake. Among species that grew in a pond in the former was the Water Lily (Nuphar advenaf) and both sheets of water were plentifully supplied with several species of Pond Weed [Potamogeton). The scarcity of the seeds of the Bog Cranberry in the bed above the Lake peat. No. 5, appears to be connected with the appearance in the Lake Basin of a grass, the seeds of which first appear in the upper part of No. 5
