Page 118 - The objects of the Association are, by periodical and migratory meetings, to promote intercourse between those who are cultivating science in different parts of the United States ; to give a stronger and more general impulse, and a more systematic direction, to scientific research in our country ; and to procure for the labors of scientific men increased facilities and a wider usefulness.
Page 340 - The basins of Lakes Ontario and Huron are taken for consideration. The previous paper upon the course of the ancient St. Lawrence shows that the Huron and Ontario basins are sections of the former great St. Lawrence valley, which was bounded, especially upon the southern side, by high and precipitous escarpments, some of which are submerged.
Page 413 - During a visit this year to the south-eastern part of the island of Cuba, the speaker had made some examinations of the rocks which form the nucleus of the spurs of the Sierra Maestra, and there is strong reason to believe of the axial range of the entire island and of Jamaica, Santo Domingo, Puerto Rico, and the Windward Islands as well. From the field observations there made, and an examination of the specimens under the microscope, it seems highly probable that these rocks, instead of being igneous...
Page 341 - This is the first chapter in the history of the great lakes and is subsequent to the deposit of the upper boulder clay, and therefore the lakes are all very new In point of geological time. By the warping movements of the earth's crust, as shown in the beaches — after the deposit of the later boulder clay — the lake region was reduced to sea level and there were no Canadian highlands northward of the great lakes.
Page 340 - Oswego, but no further traceable, as the lake bottom rose to the northeast. Upon the southern side there was a series of escarpments (some now submerged) with vertical cliffs facing the old channel. By recent studies of the elevated beaches, It Is demonstrated that the disappearance of this valley is due to subsequent warpings of the earth's crust, and that the valley of the St. Lawrence was one with that of Lake Ontario. Recent discoveries of a deep channel, upon the northern side of Lake Ontario...
Page 204 - ... generations of American citizens, loaded with the heavy burden of unfavorable hereditary conditions, adds still further to the gravity of the problems involved. The question next arises as to how many of these children are dependent as the result of parental delinquency. I examined this subject with care in a paper which I had the honor to read before the First New York State Conference of Charities and Corrections, held in Albany during November, 1900, which paper appears in the report of the...
Page 213 - Emmons,12 and even though it were also true that "all his reasons for calling the Hudson tcrrane Taconic were based on errors of stratigraphy, and it was only a fortunate happening that any portion of the Upper Taconic rocks occur where he placed them in his stratigraphic scheme...
Page 327 - The laminations of this clay conform to the curvatures and irregularities of the roof and floor of the ancient cavern, and exhibit the appearance of having flowed in while in a semifluid condition, while the hydrostatic pressure of the mass above, acting through the deep funnel, had forced the soft mass againt the walls and roof of the cavity, causing it to assume in its lamination the same contour.
Page 111 - What more is universal culture ? What more is symmetrical culture ? Who can claim any discipline of intelligence as not reached by the influence of geological learning ? I shall not institute comparisons in detail. I leave it to my readers to seek out other lines of study capable of a wider or more profitable culture. Their efforts will but enforce the truth of my conclusion. I am not so unreasonable as to maintain that geology is the only science to be studied ; or that other sciences or literatures...
Page 370 - This removes one of the most perplexing questions which geologists have encountered, for nowhere else in the British Isles is there proof of any such submergence during or since the Glacial period, the maximum known being 510 feet, near Airdrie, in Lanarkshire, Scotland.
