In some of the quartzitc and granite districts of the Atlantic coast, the surface seems to be heaped with boulders with only a little soil in their interstices, and every little field, cleared with immense labour, is still half-tilled with huge white masses popu- larly known as " ; On the other hand, in the districts of soft sandstone and shale, one may ti'avel some distance without seeing a boulder of considerable size. Though I have called these fragments untravelled, it by no means follows that they are undisturbed. They iiave been lifted from tlieir original beds, heaped upon each other in every variety of position, and intermixed with sand and clay, in a manner which shows convincingly that the sorting action of running water had notliiiig to do with the matter; and this applies not only to stones of moderate size, but to masses of ten feet or more in diameter. It is as if a gigantic harrow had been dragged over the surface, tearing up the solid rocks, and mingling their fragments in a rude and nnsorted mass. l^eside the untravelled fragments, the drift always contains boulders derived from distant localities, to which in many cases we can trace them; and I shall mention a few instances of this to show how ex- tensive has been this transport of detritus. In the low country of Cumberland there are few boulders, but of the few that appear, some belong to the hai'd rocks of the Cobcquid
