We have before us No. 15 of the Census Forestry Bulletin with a map of the State of Maine, showing the distribution of the pine and spruce forests, by Prof. C. S. Sargent. Maine seems to be acting more judiciously than some other timber districts. Pine has been cut in every township, and the largest spruce has been removed except from inaccessible regions; but the second growth is carefully protected, which allows the forest to be again profitably worked every fifteen to twenty-five years.
