generally the best pigs were in the outside Lota. YeA the meal required

Lots and ill for those in the pens on grain and green feed. At the 
close of the experimenl the pigs were sold, and the packer's report 
showed nothing unfavorable to the method of feeding. The bacon 
produced was firm and of good quality in other ways. The pigs that 
were soiled required twice as much time for attention and feeding as 
those outside.

sows confined in small pens and fed for twenty-one days a mixture of 
equal parts shorts and hominy meal with all the purslane they would 
eat. Purslane was not eaten with the relish that was expected, but 
the pigs made fairly good gains at a COSt of 2.2 cents per pound. 
Grazing chufas. — Duggar* hurdled 9 Berkshire pigs from November 
in to I December 17 on chufas, with some grain, and a mix! ore of corn 
meal and eowpea meal in addition. They gained i_l pounds, grazed 
7,986 square feet of chufas, and ate 262 pounds of grain, thus requir- 
Lng only 234 pounds of grain for LOO pounds gain. With the usual 
allowances for the gain due to the grain fed, the return per acre for 
the chufas, estimating pork at :>.l cents per pound, was $13.09. 
Grazing peanuts, chufas, and soy beans. — At the Arkansas station, 
Bennett fed four lots of half-bred Berkshire pigs to compare the 
grazing values of i hese I hree crops with pen feeding on corn. The soil 
on which the crops were grown was a sandy loam with an estimated 
capacity of 30 bushels of corn per acre. The crops named were planted 
in rows :\ feet apart — the peanuts 14 Inches apart in the rows, the 
chufas'' \- inches apart in the rows, and the soy beans drilled. The 
stand was estimated at 87 per cent for the peanuts, 75 per cent for the 
chufas, and only good for the soybeans. The corn was fed dry on 
the ear, and the grazing was done by using hurdles. The feeding

''Chufas are coarse plant- belonging to the Bedge family. Two species are used

These plants form small tubers which enable them to spread rapidly and form 
a thick, matted growth, each tuber being capable of producing B plant. The 
tuhers are relished by hogB, hut the plants are of questionable value, as it is almost 
impossible to eradicate them when once established, especially in Bandy soils.
