[No. 25. mesquite, though barely reaching the dignity of a tree and often dwarfed to a mere shrub, is the only available timber over thousands of square miles. The wood is heavy, strong, and durable. The feathery foliage, while so thin that grass grows under the trees, affords a welcome shade to man and beast. The fragrant, honey- laden, catkinlike flowers blossom quickly, and in warm weather after a good rain a crop of long bean pods will mature and ripen with.

Often two crops a year mature if rains come at proper intervals. The sugary pods serve to fatten cattle, horses, mules, burros, sheep, and goats. The small, hard beans pass through animals and seed new ground, so that the spread and increase of the mesquite has been a notable result of stock raising. The use of the sweet, nutritious pods as food by both Indians and early settlers seems to have been mainly given up, but the actual food value of the pods needs no better demonstration than is afforded b}^ the condition of animals feeding on Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Bailey, Vernon, 1864-1942; Merriam, C.
