1.19 to 1.20 pounds; Poland Chinas and Tani worths are 

 even, 1.38 pounds; in the second experiment, Small York- 

 shires 1.01 to Berkshires .9 pounds ; Poland Chinas 1.01 

 pounds; in the third experiment. Small Yorkshires 1.15, 

 Berkshires 1.35, Poland Chinas 1.38 and Tamworths 1.42 

 pounds. The Berkshires lead the Small Yorkshires in two 

 out of three experiments, while the Poland Chinas and 

 Tamworths show practically no difference in that respect. 



3. The cost of feed 2^er pound of dressed pork produced 

 varies in case of different breeds in the successive experi- 

 ments as follows : First experiment, Small Yorkshires and 

 Berkshires, from 4.79 to 4.80 cents, and Tamworths and 

 Poland Chinas 4.52 to 4.57 cents; second experiment, 

 Berkshires and Small Yorkshires 4.80 to 5.19 cents, Poland 

 Chinas 4.98 cents; third experiment, Berkshires and Small 

 Yorkshires from 5.32 to 5.61 cents, and Poland Chinas and 

 Tamworths from 5.09 to 5.52 cents. The Berkshires lead 

 the Small Yorkshires in two out of three trials, and the 

 Poland Chinas and Tamworths compare well with each other 

 in two trials. The cost of feed in the previous statement is 

 l)ased on the contemporary market price of the different 

 grain feeds, which during the third experiment were excep- 

 tionally high, as may be seen from previous reports. 



4. The average net cost of the feed consumed per pound 

 of dressed pork produced, allowing a loss of 30 per cent, 

 of the essential manurial constituents of the feed consumed, 

 compares as follows : First experiment. Small Yorkshires, 

 3.14 cents; Berkshires, 3.13 cents; Poland Chinas, 2 98 

 cents; Tamworths, 2.92 cents. Second experiment. Small 

 Yorkshires, 4.14 cents; Berkshires, 4.70 cents; Poland 

 Chinas, 4.00 cents. Third experiment. Small Yorkshires, 

 4.86 cents; Berkshires, 4.59 cents; Poland Chinas, 4.40 

 cents ; and Tamworths, 4.78 cents. The value of the obtain- 

 able manure averages in the first experiment, per pound of 

 dressed pork sold, 1.61 cents; second experiment, 1.50 

 cents; and in the third experiment, 1.48 cents, — which is 

 equal to from one-quarter to one-third of the total cost of 

 the feed consumed. The commercial value of the manurial 

 constituents of the feed consumed during our three feeding 

 experiments amounts to $12.39, of which from eight to nine 

 dollars' worth may be saved.
