Page 62 - Nor has history recorded any earthquake or volcano in other countries of sufficient efficacy to produce the phenomena of this place. The objects rent asunder are too great, the ruin is too vast and too complete, to have been accomplished by these agents. The change appears to have been effected when the surface of the earth extensively subsided; when countries and continents assumed a new face ; and a general commotion of the elements produced a disruption of some mountains, and merged others beneath...
Page 22 - The objects of the Association are, by periodical and migratory meetings, to promote intercourse between those who are cultivating science in different parts of America, to give a stronger and more general impulse and more systematic direction to scientific research, and to procure for the labors of scientific men increased facilities and a wider usefulness.
Page 66 - That the Indians customarily burned, every year, such parts of the forests, as were sufficiently dry to admit of conflagration: That these were the only grounds, which except in rare cases, could be successfully burned: That, wherever they have been for a considerable length of time free from fires, the young trees are now springing up in great numbers; and will soon change these open grounds into forests, if left to the course of nature.

Gentlemen, we have come to study our duty as scientific men, and especially as American scientific men. We are to learn the apparent, and not very pleasant paradox, that America cannot keep pace with Europe in Science except by going ahead of her.
Page 60 - One could continue at length with quotations that show the sensitiveness, the vast learning, the curiosity,' and the originality of this astonishing Virginia farmer. He had, as they say, pretty nearly everything. In the field of natural philosophy he had caution and daring, inquisitiveness and a willingness to change his mind in the light of new facts or as a result of further thought. What we would now call proper scientific methods and attitudes appeared to be instinctive with him.
Page 66 - The origin of the peculiar appearance of these grounds is probably this. The Indians annually, and sometimes oftener, burned such parts of the North .American forests, as they found sufficiently dry. In every such case the fuel consists chiefly of the fallen leaves ; which are rarely dry enough for an extensive combustion, except on uplands ; and on these only when covered with a dry soil. Of this nature, were always the oak, and yellow-pine grounds ; which were therefore usually subjected to an...

When we commenced our journey on this Island ; I proposed to my companions to examine with a continual, and minute attention, the stones, of every size, which should be visible to us throughout all the parts of our progress. This examination was made by us all with great care ; and was extended to the stones on the general surface ; to those, washed out in hollow roads ; to those uncovered on the summits, and sides, and at the bottom, of hills ; to those, found in the deepest vallies ; and to...
