in a slightly oblique direction, with two or three turns, to a 

 depth of aboui fourteen inches, where it ended in a pocket, with 

 a capacity of over a pint, half filled with water, in which the 

 animals were found. From the main shaft extended a number 

 of passages. One of these branched, one branch ending in a 

 low, closed chimney at the surface, while the other ended about 

 an inch below the surface. The remaining side tunnels, one of 

 which branched, ended in pockets, the capacity of one of which 

 exceeded a quart. The entrance and exit to the pockets was by 

 the same tunnel. That they were not the accidental result of a 

 deepening of the tunnel, on account of the lowering of tlie 

 water, but were constructed for some purpose, was shown by 

 their size and form, and by the fact that in many cases the en- 

 trance was from below, as would not be the case were they tlie 

 result of changes in the depth of the tunnel. At some places 

 in Fern Hollow the ground was honeycombed with burrows, 

 and it was sometimes possible to show that the tunnels of 

 several chimneys were connected. In habits the animals are 

 nocturnal, specimens being found in the traps set for small 

 mammals.
