The breach pre- viously made had destroyed it for beaver POND Ground Plan of second Boaver Burrow nt Qrass Lake. i III About twenty feet above the great dam, and upon the south side of the pond, is the burrow represented in the above figure (Fig. 17). It ascends with the bank, which it enters under the roots of a tree, is ten feet long, and has a chamber twenty inches in width and a foot high. It terminates under the roots of a pine-tree, where its roof comes within four inches of the surface of the ground. It is a good specimen of the ordinary burrow. North of the Cleveland Mine there is a natural pond, shown on the map, which will be more particularly de- scribed hereafter. The canals which enter it have a number of burrows upon their upper portions, one of which is represented in the figure (Fig. 18). This bur- row is shown in Plate XVIII., and is the one nearest to the pond. It was found open at the centre and also at the extreme end. The length of the passage-way from the canal was eleven feet, and this communicated with a chamber three feet two inches by two feet and a half.
