The financial statement is based on corn at 40 cts. and cowpeas at 

 50 cts. per bushel, and wheat bran at $15 per ton. The results of the 

 second period are briefly shown in the following table:

The pigs were slaughtered and sold for 3 cts. per pound. At this 

 price the corn fed is valued at 62 cts., the cowpeas at 62 cts., the corn 

 and cowpeas at 69 cts., and the corn and wheat bran at 58 cts. per 

 bushel. The financial returns for the different rations fed are discussed 

 at some length. In the author's opinion such returns would only be 

 profitable in a year of low prices for feeding stuffs, unless certain indi- 

 rect benefits from feeding cowpeas are taken into consideration (green 

 manuring, etc.). 



The proportion of fat to lean in the different carcasses is discussed. 

 On an exclusive corn ration the proportion of fat was greatest, aver- 

 aging 2.3 per cent of the live weight; and on the cowpea ration least, 

 averaging i.l per cent. 



The urine and feces from the different lots of pigs were collected for 

 2 days and samples analyzed. The fertilizing constituents excreted 

 in 24 hours by the 4 lots are shown in the following table:

The smallest quantity of manure was produced by the pigs fed corn 

 alone. In the author's opiuiou this was due to the fact that they con- 

 sumed less water. " The total value of the manure produced is consid- 

 erably greater when the ration consists of cowpeas or of part cowpeas 

 or wheat bran than when corn only is fed." 



Molasses feed for pigs, G. Faye and E. Frederiksen ( UgesTcr. 

 Landman, 42 {1897), pp. 15-17). — In continuation of previous work (E. 

 S. R., 8, p. 519) the authors report experiments on the value of molasses 

 feed for young pigs. Twenty pigs, weighing on an average 25.5 lbs., 

 were divided into 4 lots. All the pigs were giveu a basal ration of
