The discussion of the origin of our prairies, and of the distribution of our native forest trees, is as old as our knowledge of the central northwest. The earlier discussions were based on a knowledge of conditions as they existed when the white man first appeared in this section, and, though some of them are crude, and based upon insufficient observation, they fortunately give us at least a partial record of those conditions.
