In the permanence, therefore, of a coat of vegetable mould on the surface of the earth, we have a demonstrative proof of the continual destruction of the rocks...

Página 256 - In the North-western provinces of Canada wheat often produces 40 and 50 bushels to the acre, while in South Minnesota 20 bushels is the average crop, in Wisconsin only 14, in Pennsylvania and Ohio 15. The fact established by climatologists that the cultivated plants yield the greatest products near the northernmost limit at which they grow, is fully illustrated in the productions of the Canadian territories...

The flints are met with on the surface at various points along that line. The ridge is bare and moorish, but covered with peat and heather, and this prevents the flints from being accurately traced.

But it may be argued, The greensand beds lay right in the way, and must have suffered also from the denuding power of the waves. If future examination shows that these beds are in...

The other runs north of Buchanness and may be said to terminate in the granitic escarpment of the Black Hills. All along the shore between these points, wherever the rocks admit 'of a beach, quantities of water-worn flints are found mingled with the other pebbles, evidently brought there by the...
