"The pigs that ate the most gained the most, but . . . the extra 23 Ihs. live weight 

 cost $1.93 more, or 8.4 cts. per pound, whereas it only brought 7 cts. This is a 

 reversal of the results found with 8 pigs last year [E. S. R., 5, p. 318], but, as before 

 stated, pig 3 [in lot 2] did so ]ioorly that he lowered the average and the results are 

 less satisfactory than might be wished."
