were slaughtered and the melting point of the fat determined, 
continuing in this manner until all tin- pigs were slaughtered, bo thai 
the last pi.u r s to !><• slaughtered had been on corn eight weeks. 
The pigs used in tin- 1899 experiment were natives, not over one- 
fourth of improved i>l<>od. They were from ten t<» twenty months old 
and a\ eraged about 1 15 pounds in weight. 
In L 900 the feeding was as follows: Lot I grazed on a field of alter- 
nate rov< a of peanuts and ohufas for seventy-five daj s, receii ing some 
corn in addition. Lot II grazed a field of alternate rows of peanuts 
and chufas for fifty days, and for twenty-five days received a quan- 
tity of com equivalent to that fed the above lot. Lot III grazed 
peanuts for seventy-five days and had corn as Lot I. Lot IN' grazed 
peanuts as above for fifty days and had corn for twenty-five days as 
the preceding lots. Lot V grazed on peanuts and had corn at the 
same time for seventy-five days. Tin- pigs of this lot were purebred 
Berkshire*, and were used to determine the effect of improved blood 
on the melt ing point of lard. 
The quality of these pigs was somewhat higher than in the experiment 
of i^:»".». The pigs of Lots I to IV were from eight to twelve months old 
at t he beginning; the purebred pigs were from six to eight months old. 
'The gains of the pigs, while incidental to the main purpose of the 
experiment, arc of much interest. Those for L899 are as follows:
