 but breeds before that time. According to Indian 

 report, it pairs in February, and after carrying its young

In an old work on America (p. 174), we find that, 

 speaking of New York, " The Beaver live in the Water 

 and on the Shore in great Companies together, in Nests 

 built of Wood, which deserve no small admiration, being 

 made after this manner : The Beaver first gather all
