I have never been able to decide which I love best, birds or trees, but as these are really comrades it does not matter, for they can take first place together. But when it comes to second place in my affection for wild things, this, I am sure, is filled by the beaver. The beaver has so many interesting ways, and is altogether so useful, so thrifty, so busy, so skillful, and so picturesque, that I believe his life and his deeds deserve a larger place in literature and a better place in our hearts. His engineering works are of great value to man. They not only help to distribute the waters and beneficially control the flow of the streams, but they also catch and save from loss enormous quantities of the earth's best plant-food.
In helping to do these two things, -- governing the rivers and fixing the soil, -- he plays an important part, and if he and the forest had their way with the water-supply, floods would be prevented, streams would never run dry, and a comparatively even flow of water would be maintained in the rivers every day of the year.
