Strana 136 - ... prove that they are of unwonted interest. Besides the peculiar interest which attaches to them as the earliest known traces of insect life on the globe, there is very much in themselves to attract and merit our closest attention. One of them is a gigantic representative of the family of...
Strana 16 - Its colours are white and gray, with dark graphitic laminae ; and it contains occasional bands of olive-coloured shale. It dips at a very high angle to the south-east. Three beds of impure graphite appear in its upper portion. The highest is about a foot in thickness, and rests on a sort of underclay. The middle bed is thinner and less perfectly exposed. The lower bed, in which a shaft has been sunk, seems to be three or four feet in thickness. It is very earthy and pyritous. The great bed of limestone...
Strana 16 - I shall state in some detail, as the precise age of the St. John series has not until now been determined. The oldest rocks seen in the vicinity of St. John are the socalled syenites and altered slates in the ridges between the city and the Kennebeckasis River. These rocks are in great part gneissose, and are no doubt altered sediments. They are usually of greenish colors ; and in places they contain bands of dark slate and reddish felsite, as well as of gray quartzite.
Strana 119 - Kobb, on the contrary, was of the opinion that no rocks of this age occur on the north side of the Bay of Fundy. There are, however, three very limited areas on the bay-shore, in the Distribution, counties of St. John and Albert, where deposits of this period do exist. The first is between Gardner's and Ten Mile Creek, one and a half miles long and half a mile wide. The second is at Quaco, where they may be seen in the depressions east, south and west of Quaco Head. They underlie the village, and...
Strana 136 - I have made as careful an examination as my present circumstances will permit of your most interesting collection of the fossil remains of insect-wings from Lancaster. There are ten specimens in all, eight of which are reverses of one another, thus reducing the number to six individuals; of these, one, a mere fragment, belongs, I think, to the same species as another of which the more important...
Strana 137 - ... questions; but these few remains, coupled with the pair of insects found in Illinois, induce us ardently to anticipate that the future study of fossil insects, drawn from such ancient strata as these, may lead to as brilliant and important results, in the elucidation of geological problems still open, in widening the range of our...
Strana 152 - ... the north-west side of this long granite belt, and is even longer. In Maine, in an essentially unaltered form, it extends to the Saco river; and in the province it extends quite to the Bay of Chaleur, a total distance of three hundred and seventy miles; its width varying from nine to forty miles. It would not be strange if the name Cambrian which was applied to both these belts of mica schist in New Brunswick many years ago, and is now generally discarded, should ultimately prove to be their...
Strana 28 - ... glistening surfaces owing to the abundance of minute spangles of mica. This rock frequently becomes very fine in lamination and texture, and dark in colour. Four thick bands of this kind occur, the uppermost of which has been denominated by Dr. Dawson papyraceous shale. They have as yet yielded no fossils.* The three bands of coarser shale which alternate with them include numerous layers of a fine compact grey sandstone, from a few inches to ten feet or more in thickness ; a few are so highly...
Strana 31 - The lower part of the St John group, at Coldbrook, has been divided by Mr Matthew, on lithological grounds, into three bands, viz. : — " No. 1. The lower or arenaceous band, with no determinable fossils, and constituting passage beds from the Coldbrook group. " No. 2. Argillaceous shales, rich in fossils, Paradoxides, Orthis, Conocephalites, Obolella.
Strana 135 - A single insect's wing was obtained from this bed by my father and myself. PLANT-BED No. 8 1 foot 10 inches. Fine-grained, tough, but fissile sandstones, rather coarse shales, often of a greenish cast, and at the top a thin layer of very black shale very rich in plants. The middle portion does not contain so many plant remains, but the lower is as well stocked as the leaves of a herbarium. The following are the fossils I have collected from it:— Cordaites Robbii, Daws. As usual in great profusion,...
