159 In carrying out our purpose we secured two hogs of good average condition, and caused them to be slaughtered. The animals chosen for the experiment were of the Poland-China and Berkshire breeds respectively, and were both females. It was our desire to secure not only of the same breed and sex, but those of the same age similarly fed; but in this particular, as our figures show, we were disappointed. It seemed impossible to secure animals of exactly the same age, but both had been corn fed, and it is therefore to be presumed they had all they could eat and digest. One of the animals, the Poland-China, had been fasted previous to slaughtering, and the other lately fed, but it is believed this could affect only the entrails. They were slaughtered in the afternoon, and all the parts of offal collected as completely as possible. Each part was weighed and the weight recorded. The carcass was then divided into two parts, in the direction of its length, and allowed to cool over night. On the following morning one side was carefully skinned, the fat separated as completely as possible from the flesh, and both from the bones, and all weighed separately. Each part was then chopped into small pieces, and samples taken from each lot for analyses. The results of slaughtering are as follows: POLAND CHINA. BEBKSHIEE. A g e , 11 months. 340 l b s .

In the percentage figures we find some important differences for the same parts. Thus we find that the Poland-China has nearly one pe* cent, more of blood than the Berkshire, while as regards the internal organs, those of the Berkshire are 3 per cent, heavier than those of the Poland, when referred to total weight of carcass in each case respectively. In the latter, however, the percentage of flesh is lower and that of fat higher in every part. We have a loss in both cases that can not be accounted for, of 10.29 per cent, in one case, and 8.87 per cent, in the other. The differences here appear to be in favor of the Poland breed, and these conditions are further supported by the chemical analyses.
