upwards, I found that, about one hundred and 

 forty feet distant from the uppermost pond, it 

 connected with the waters of the brook on which 

 the old colony formerly had a place. This tunnel 

 over most of its course was about two feet be- 

 neath the surface, was fourteen inches in dia- 

 meter, and ran beneath the roots of spruce trees. 

 The water which the tunnel led from the brook 

 plainly was being used to increase the supply 

 needed in the canals, ponds, and pools of the 

 Spruce Tree Colony. The intake of this was in 

 a tiny pond which the beaver had formed by a 

 damlet across the brook. That this increased sup- 

 ply of water was of great advantage to the busy 

 and populous Spruce Tree Colony, there can be 

 no doubt. Was this tunnel planned and made for 

 this especial purpose, or was the increased water- 

 supply of the colony the result of accident by the 

 brook's breaking into this subway tunnel ? 



The canals which beaver dig, the slides which 

 they use, the trails which they clear and establish, 

 conclusively show that these animals appreciate 

 the importance of good waterways and good roads, 

 in other words, good transportation facilities.
