dricsd, in which condition it is unpalatable. Compared with our 

 Six-"feeks gramas this is superior both as forage and as a ground 

 cover. It remains green much longer but furnishes forage in the 

 winter instead of late summer* 



Mr. Gambee of Phoenix, Arixona has devised a small machine 

 which he pushes by hand like a lawn mower on which he has mounted 

 a snail gasoline engine to run the stripping devise, he lias used 

 this machine quite successfully in collecting Schismus seed, 



Sclerop ogon brevif oliur, Burro Grass, is relished by ani- 

 mals other than burros. It is one of the things that is so very 

 common that it is poorly appreciated. It occupies large areas 

 often of very dry flat land but not infrequently it extends up the 

 more gentle slopes. It's a heavenly gift to fools who insist on 

 grazing the last spear of grass fro?-: the range. Vvhile it is flower- 

 ing and fruiting the long awns are forbidding to stock but after 

 the seed are mature and fall the grass forms a good winter pas- 

 turage and the long rhizomes are very effective in binding the soil. 

 Its normal range is western Texas, southern Hew Mexico, southern 

 Arizona and Mexico. It occurs also in Argentine, South America. 



Setar ia macro st achya . The Bristle grasses are among our 

 most drought resistant grasses in the extreme southwest, growing 

 in many places where the rainfall is less than five inches. They 

 are also among our keenest disappointments. The seed is very 

 poor, most of it empty, Vvhile the germination is fair the trans- 

 planting which is very necessary is all but impossible. We may be 

 able eventually to sow the seed directly in the field which may 

 give us desired results. The heavy roots with numerous rootlets 

 suggest that plants could be transferred from the field to the nur- 

 sery and thus valuable strains secured. Almost invariably such 

 transplanting results in killing the plants. 



South of Carlsbad wo secured a strain of this which has 

 largo rhizomes. In case our transplants all prove failures we may 

 succeed in getting seed later in the season. YJhon we learn how to 

 handle these plants we will add a very desirable grass to our 

 r e ve g e t a t i o n program. 



The Setarias grown from seed at Tucson in 1937 gave remark- 

 able results, '-has we have called S.. macr o st achya from different 

 localities proves to be practically as many well defined strains 

 as we have localities represented, Ae may have more than one 

 species. S_j_ mac rp stachya t for example, from the Baboquivari Moun- 

 tains is two feet or more tall and has coarse stalks and wide leaves.
