It will be seen that, as is almost invariablj the case in fatten- 

 ing pig's, the highest return in flesh lor the food consumed was 

 obtained within the first month of the fattening process ; the 

 second period gives a much smaller return for each one of the 

 pigs. In the case of Pigs Nos. 3 and 4, the return is still smaller 

 in the third and fourth periods, so that thej became less and 

 less profitable as the experiment advanced : on the other hand, 

 the thoroughly healthy pigs, Nos. 1 and 2, were more profitable 

 in the third and fourth than they were in the second period. 



From the last line in the table we see that less food was 

 required to produce 100 lbs. increase in live weight at the 

 beginning than at the end of the process of fattening. 



The average for the whole period of 94 days shows that 

 561 lbs. of dry organic matter was needed to produce each 

 100 lbs. of increase. In the experiments at Rothamsted a 

 similar increase was obtained from the consumption of smaller 

 quantities of food. Mr. Lawes used various combinations of 

 meal, from barley, beans, lentils, and Indian corn, with some- 

 bran. Taking the average of twelve pens of three pigs each,, 

 we find 100 lbs. of increase was obtained at Rothamsted from
