In 1880, three half-acre plats were selected from this same tract of land—they having been in corn in the intervening years without manure. Corn was planted in rows so as to have four to each rod, and with design of having two stalks each two feet in the rows. The "stand" was not good. One half-acre plat received two twohorse loads of barn-yard manure, and gave 20 bu. 15 lbs. of corn; one plat received 100 lbs. superphosphate of lime and gave 17 bu. 45 lbs. corn; the third plat had no manure and gave 16 bu. 30 lbs. of corn. Superphosphate of lime was applied to the other plats of corn in 1880, with slight benefit in one case, and with no appreciable effect in another.

EXPERIMENTS IN MODES OF CULTURE.

In 1879 a set of experiments in corn culture were planned and carried out by E. F . Lawrence, head farmer, whose report of results is subjoined in full:
