Jepson Field Book volume 26 page 142
Yuma, Ariz. ---------- so much interest in plants, I say: There is no limit to them. There is no limit to their production and productive powers, no limit to size or variety, that has yet been reached. There is no limit to what we can learn about them". - Visited the Datefarm Exp. Sta. of Univ. Ariz. 2 miles east of Yuma. They have trees producing dates which we sampled. The production per acre of crops under special care on the farm is hardly credible. Tepary Bean (Phaseolus acutifolius var. latifolius) is very productive. See Univ. Ariz. Agr. Exp. Stat. Timely Hints no. 92. The Indians prefer this native bean to all others. ::::::::: 7 Nov. 1912 ---------- - Visited the Federal Exp. Farm at Bard. They have dates, cotton, milo maize, roselle, figs (which froze down to the ground last winter) etc. The figs resprouted & one sprout is making into a new tree by pruning. They hope by mild winters to get them established so frost will not matter. Subsoil water is the great problem here now. Met O.F. Cook who is here. He called my attention to the small leaf form of Populus fremontii as exhibited by a tree on the farm, the leaves small and almost rhomboidal. A little of this I had noted up the river and the form shows in one of my spms. ---------- - Arroweed. Indian house near Ft. Yuma, Cal, studding & beams & rafters = Populus fremontii; lathing = Salix nigra; wattling = Pluchea sericea. No adobe used. See photo.
