Yorkshire being the only breed iliai shows mnch variation from the 
general average. The variation in. weights of Livers and Inngs i*> 
quite erratic. Poland Chinas Lead in relative weight of Livers, with 
L.66 per cent, the other breeds following thus: Berkshire, Chester 
While, Duroc Jersey, Yorkshire, and Tamworth, the least amount 
being L.28 per cent of the Live weight. The Tamworths Lead in rela- 
tive weight of lungs, w it li 1 . (| 1 per cent, the other breeds following in 
this order: Yorkshire, Berkshire, Duroc Jersey, Chester White, and 
Poland China, the Lowest weight being 0.69 percent of the live weight. 
We find some appearance of uniformity in the weights of stomach 
and intestines. The heading '"Total weight of guts" includes, among 
others, the three items that follow it. Tin- Berkshires lead in this 
respect, with LI. 19 per cent, the breeds following thus : Duroc Jersey, 
Chester White, Tamworth, Yorkshire and Poland china, the Lowest 
weight being 9.3 percent of the Live weight. The Duroc Jerseys lead 
Ln net weight of bung guts, with 0. 1 per cent, the breeds following in 
this order: Tamworth, Berkshire, Poland China, Yorkshire, and 
Chester White, the lowest weight being 0.26 per cent of the live 
weight. The Tamworths Lead in net weight of small guts, the weight 
being 1.37 per cent; the other breeds stand thus: Duroc Jersey, Berk- 
shire, Chester White, Poland China, and Yorkshire, the Lowest weight 
being 0.9] percent. In net weight of stomachs the Tamworths lead, 
the breeds following in this order: Duroc Jersey, Berkshire, Chestei 
White, Yorkshire, and Poland China, the weights ranging from 0.74 
per cent to 0.61 per cent of the Live weight. The record of the Berk- 
shires and Duroc Jerseys is seen to be fairly uniform. Definite con- 
elusions can not bedrawn from these figures and it may be questioned 
whether, in the Light of the fads concerning the feeding possibilities of 
the differenl breeds on similar rations, the improved breeds will show- 
any marked and uniform differences in the relative weights of the 
internal organs when U-<\ on the same feed. 
Lard yii Id ofdifft n ntbn < ds. — By common consent, the name " lard 
hog "has beeii applied by many people to that type of animal the 
development of which lias very Largely been brought about on Amer- 
can soil, in cont radisl inct ion from the "bacon " type of hog winch has 
been brought to us from Great Britain and Canada. 
The writer is under obligation to Swift & Co., Chicago, who killed 
the hogs used in the Iowa experiments, for the following information 
regarding the lard yield of the different breeds in the test of L898, 
Concerning their figures, they say: 
We did not, on any of the testa made, tank the fata of each Lot separately, the 
amonnta being too small. However, we know approximately what theai 
should yield in rendered lard, and we have attached herewith a statement show- 
ing the different test lota slaughtered by us during November, i s '. ,s . and what we 
estimate the fata, etc., shonld yield in lard. 
Pot your information we beg to say thai the ham facings, heads, cheek-meat 
tat . u'ull.t fat, gat fat . can] and raffle fat, bonea, tails, feet, and fat trimmings are,
