lizer was used, and the whole treatment at planting and afterwards as 
duplicate plats, cultivation having been practiced on May 21, June 6 
and 7, June 25, July 11 and August 1. Harvesting took place Septem-

The question under investigation was as to the adequacy of the plat 
system to offer decisive results. 
The land was in old sod in 1882, when possession was taken of the 
farm, and was first broken up in 1884, and from this date was subjected 
to various treatments and fertilizations. But three series have been 
exact duplicates from the commencement. These were: F 3 and F 4, 
corn, and 400 lbs. of fertilizer per acre in 1884; squashes, manured in 
the hill, in 1885; and potatoes, 400 lbs. of fertilizer per acre, in 1886.
