Forest Service and published by the respective states, give the amount of each kind of wood used by manufacturers (i. e., that which passes beyond the stage of rough lumber, even if it is merely planed) in each state in a year, and distinguishes between lumber cut within the state and that

brought in from other states. From these we learn that the manufacturers of Michigan use in a year about 10 million feet of home-grown red pine, those of Wisconsin something over 6 million, and in Minnesota 167 million. (The corresponding figures for white pine are 70, 72 and 455; and both added together are less than half the total lumber production of the two species for these states as reported by the Tenth Census.)

The Hemlock (Tsuga Canadensis) has a distribution very similar to that of the white pine, except that it is a little more southerly. It grows in several counties of Alabama, in which state the white pine is unknown. It commonly grows mixed with various hardwood trees and sometimes with white pine besides. It prefers moderately dry soils with considerable humus, perhaps more than any other eastern conifer. (The
