eat, with a little corn meal stirred into it," diirin<!; 63 days. The tabu- 

 lated results show that the food consumed per 100 pouuds of gain was, 

 in the case of the mature hogs, 1,430 pounds skim milk and 301 pounds 

 corn meal, and in that of the growing hogs, 1,024 pounds skim-milk 

 and 174 ijouuds corn meal. 



Experiments icith pigs before and after iceaning (pj). 24-31). — As 

 experiments on this subject were continued in 1890, the two years' work 

 is treated together, j). 438. 



Length of intestines of hogs (pp. 31-33). — According to tbe tabulated 

 results of measurements of thirty-nine hogs the total length of the large 

 and small intestines ranged from 18 to nearly 25 times the length of 

 the body. 



Darwin puts it** as 13.5 to 1, so that uow we may say that the intestines of the 

 modern, improved hog are nearly two and one half times as long as those of the wild 

 hog, and nearly one and one half times as long as those of the common animals from 

 which the data used by Darwin were obtained. * * * It may not be that the 

 modern hog can digest his food any more thoroughly than his ancestors, though I 

 suspect he can, but it is altogether probable that he is enabled to eat larger quanti- 

 ties of food in a given time, and therefore gives better returns for what is fed him. 



Relation between weight of hogs, gain made, and food required for 100 

 pounds of gain (pp. 33-35). — A table is given showing the relation 

 between weight of hog and food eaten, gain made, and food required for 

 100 pounds of gain, condensed from " the results of over one hundred 

 feeding trials with over three hundred hogs, ranging in weight from 

 under 50 to over 300 pounds," with a discussion of the same. 



Fraetical conclusions (pp. 36-41). — A popular discussion of the sub- 

 ject of pig feeding. 



tSummary of pig-feeding trials (ap[)endix, pp. 233-243). — " All the 

 more important data relative to the various feeding trials at this sta- 

 tion" are summarized in tables, and general averages are deduoed for 

 pigs of different weights. 



Variations in the yield and quality of milk, S. M. Babcock, 

 Pil. D. (pp. 42-62). — Observations during the month of April of the 

 milk of four cows taken at random from the station herd showed an 

 average daily variation of from 1.18 to 1.8 pounds of milk; and tests 

 made of the amount of fat in the milk of five cows for one week in 

 April showed "an average daily variation of about 8 percent in the 

 yield of fat." 



MiUcing one teat at a time (pp. 44-47). — At the evening milkings in 

 several cases the milk of each teat was kept by itself, to be weighed 

 and tested for fat content. "At each milking the teats were milked 

 in a different order than at the preceding milking, so that after four 

 milkings each teat had been milked first, second, third and last." The 

 results are piesentod in tables. At any single milking there was " a 

 decided difference in the (piality of milk from the dilferciit teats," that
