The descriptions which have recently been published* of different
parts of the Labrador Peninsula not visited by me, favour the sup-

of the Moisie River.
§ 2. The Forced Arrangement of Blocks of Limestone, .$fc, in Boulder-
Clay.

arrangement of blocks of limestone and gneissoid rocks in the clay
on the south branch of the Saskatchewan observed in 1858.
I concluded the description of this remarkable arrangement with
the following hint at their origin
