As a whole, the grasses analyzed contained a somewhat smaller pro- 

 portion of water and somewhat larger proportions of nutritive mate- 

 rial than the nonsaccharine and saccharine sorghums. As was the 

 case with the sorghums, carbohydrates constituted the chief nutritive 

 material. 



LEGUMINOUS FORAGE CROPS. 



Leguminous forage crops are, generally speaking, of special value 

 on account of their fairly high protein content, as compared with 

 grasses, and several sorts of leguminous crops were analyzed which 

 were considered of especial interest in the feeding of animals in 

 Hawaii. 



Where irrigation is practicable in the vicinity of Honolulu, alfalfa 

 is being very successfully grown. When once a good stand is obtained, 

 it is possible to make from twelve to fifteen cuttings a 3^ear, and while 

 data as to the weight obtained per cutting per acre are not available, 

 it is certain that the yield is high. Of the samples analyzed, No. 1 of 

 the table was Turkestan alfalfa from Waialae, cut young; No. 2, ordi- 

 nary alfalfa from Waialae; and No. 3, from Kapahula. 



The sample of the wild cowpea ( Vigna sandwich en s is) was grown at 

 Wahiawa; Spanish clover (Desmodium uncinatum) and Desmodium 

 triflorum were grown on the station grounds.

The leguminous forage crops analyzed showed a variable but gener- 

 ally high water content. They contain fairly high proportions of 

 carbohydrates in proportion to their total nutritive material and on 

 an average considerably more protein than the nonleguminous crops, 

 the high protein content being a well-known characteristic of this 

 class of plants.
