The cowpea evidently afforded a rather firm lard, but 

 our tests do not show exactly how it compared with corn 

 in this respect. 



GRAZING SORGHUM AND COWPEAS. 



Septemiher 14th, 1900 twelve pigs recently weaned 

 (litters N and P.) were divided into four lots of three 

 pigs each. The different lots were quite evenly matched 

 in all essential respects and weighed respectively 175.5, 

 176.5, 170.5 and 193 pounds per lot. The experiment 

 lasted five weeksi in addition to the preliminai-y period. 



Lot A was confined bv means of movable hurdles on 

 drilled sorghum, in dough and ripening stages, and was 

 supplied with what was regarded as a, half ration of 

 a mixture of two-thirds corn meal and one-third cow- 

 pea, meal by weight. 



Lot B was penned on sorghum alongside of lot A; 

 no grain Avas furnished to this lot, but instead' ripe Span- 

 ish peanuts were pulled and thrown in the pen daily in 

 quantities estimated as furnishing about a half ration 

 of peanuts. 



Lot was hurdled on drilled ^A^hippoorwill cowpeas on 

 which the pods were ripe, and this lot received no other 

 grain. 



Lot D was confined in a small bare pen and furnished 

 with as much as the pigs would consume of the same 

 grain mixture as that supplied to lot A. 



Grain eaten, area of sorghum^ coicpeas, and pewnuts 

 grazed, and groicth made in five tceeks by three 



pigs in each lot.
