Cer- tainly the red m...an had done less. Thousands of acres of fertile valley land now tilled by Amer- ican plowmen was ___^ levelled up behind beaver dams. These followed one another in close succession in the valley of many a woodland stream. The wash from the hills settled in their basins. As they were filled, dams were built higher, and thus the rich soil grew deeper. The beaver was a builder of ponds. His only method was by damming gentle streams. He cut down trees with his great chisel-like teeth, trees often six, eight, or ten inches in diameter.
