yields from sowings made during the following month were 

 slightly less. Sonora sown as late as March 10 gave a low yield. 

 The indications are that the earlier grain is sown after the first of 

 November, the heavier the yield will be. 



Sonora was sown to be irrigated by three different methods; 

 by flooding, in drills to be irrigated in furrows, and broadcast to 

 be irrigated by furrows. The last method gave the highest yield. 

 The wheat was sown broadcast, and furrowed and covered by one 

 operation with a machine devised for the purpose. A man and 

 four horses could put in five to ten acres per day by this method. 



HAY FROM GRAINS. 



As the only members of the grass family used for hay in this 

 region are wheat and barley, experiments with each were made. 

 Sonora wheat sown November 10 gave a yield of 3.5 tons of hay 

 per acre on adobe soil. Upon account of the scanty foliage of this 

 variety, the hay from it is not as desirable as that from a more 

 leafy variety. Feld-spar proved to be more leafy, and thus pro- 

 duced a better hay, the yield being equal to that of Sonora. 



Three varieties of barley were tested: hull ess, Fowler beard- 

 less, and bearded. The yields of hay per acre were as follows in 

 adobe soil, from sowings made November 7: Hulless, 4.1 tons; 

 Fowler beardless, 4.6 tons; bearded, 4.9 tons. The excess of yield 

 of the bearded over the beardless was probably due largely to the 

 presence of the beards on the former. The hulless and beardless 

 varieties make more rapid growth during thecool weather of win- 

 ter, and were ready to cut ten days earlier than the common 

 bearded variety. Since they yield almost equally well, and are 

 free from the objectionable beards, they are much preferable for 

 hay. 



FORAGE CROPS. 



During 1899 four varieties of sorghum, six varieties of Indian 

 corn, two varieties of Kaffir corn, Egyptian corn, teosinte, two 

 varieties of millet, and three varieties of cowpeas were grown as 

 forage crops. The club-head sorghum commonly grown in the
