The dams were built for the most part of sticks with a liberal application of mud and stones dumped in afterward. The beaver uses his front feet for conveying mud, like a Thromorrys, and does not carry it on his tail as has been supposed by some. Altho the beaver cuts considerable alder wood we did not find a single limb with the bark peeled off so that it is evident that they use this wood in their dam works and do not eat the bark as one might suppose at first sight. They seem to feed mainly on Spruce bark. They prefer willow but that only grows in a few favored localities. If no Spruce is to be had they eat crabapple and huckleberry. All of the specimens secured were fat and in good condition. The majority of the beavers lived in the banks while others were civilized (lived in houses). Most of the bank beavers were old bachelors so needed no house. We saw 3 or 4 beavers out in the bright sunlight
