The financial statement for Lot II is as follows— based 

 on pork at 3 cents per pound and corn at 40 cents per bushel i 



By 122 lbs. of live pork at 3c. per lb 



To 263.8 lbs. of corn at 40c. per bu ; 



To balance: Value of 7,280 sq. ft. in covvpens,

This is at the rate of $10.65 per acre. This is certainly 

 not a large return for an acre, but to this value of pork pro- 

 duced by an acre of cowpeas should be added the fertilizer 

 value of the vines, which is considerable, as every farmer 

 knows. There is reason to believe that vines and excrement 

 on a field where pigs have grazed are worth practically as 

 much for fertilizing purposes as the vines on a similar area 

 not grazed. 



A return of 110,65 per acre, a figure which was obtained 

 from an acre capable of yielding 13.2 bushels of peas, is not 

 to be expected from land poorer than that used in this expe- 

 riment. 



It was planned to duplicate the experiment just detailed, 

 using two Essex sows and their litters, both of the same age 

 and breeding. A few days after farrowing, one sow and her 

 litter were placed in hurdles on the cowpea field referred to 

 above; as much shelled corn was fed as this lot would eat. 

 The other sow, with her litter, received only corn. The expe- 

 riment was brought to a premature close by the sudden death 

 (from hog cholera and swine plague) of the sow receiving 

 only corn. Daring three weeks, when both sows were in 

 health, the sow and six pigs on cowpea pasture and supplied 

 with corn made a total gain of 29.9 pounds. The other lot, a 

 sow and seven pigs, receiving only corn, lost during this 

 period 9 pounds. As usual just after farrowing, both sows 

 lost weight — the one on corn alone 42 pounds, the other 9.1
