In Prince Edward Island, as in other parts of North America, the rocks which form the basis of the country are covered with a deposit of sand clay and fragments of stone, indicating the action, at some former period, of powerful currents ofwater,and pro~ T bably of other agents. In the neighbourhood of‘ Charlottetown, this deposit consists of red coloured sand and clay, derived from the abrasion of the sub- jacent rocks, intermixed with fragments of red sand stone usually small. Westward of Charlottetown, it contains in some places great numbers of rounded and water-worn masses ofthis stone, and wherever I had an opportunity ofexamining it, also a few frag- ments of coarse grey sand stone, differing from any

which appeared in place.

Scattered over the surtace at long intervals, a few ofthese erratic blocks,-tho’ rare, appear to be rather uniformly dispersed, and some of them are oflarge dimensions. Their small number in the vicinity of Charlottetown, is rather remarkable, as l have been informed that they are very numerous in the north- ern parts of the Island, and on the opposite shore ofNova Scotia they are extremely abundant. As these blocks belong to formations much more ancient than those found in P. E. Island, and not occurring in places within great distance ot it, they afford a striking indication of the power and extent ofthe last great revolution to which the earth has been sub—

jected.
