These figures with potatoes certainly offer no encouragement in 
favor of the plat system, and suggest what other considerations make 
probable, that the physical relations of our soil have a greater influence 
on crop than do the chemical relations. 
We may perhaps be excused if we add, in the form of a postscript, 
fuller details concerning the two plats of largest and smallest yield. 
Feb. 8. Yield 542.7 lbs. merchantable and 28.2 lbs. unmerchantable crop 
Feb. 21. Yield 241.2 lbs. merchantable and 27.0 lbs. unmerchantable crop. 
Difference 321.5 lbs. 1.2 lbs.

F 8 in 1884 was planted with melons, with manure in the hills; in 
1885 was planted to tomatoes, without manurial application; in 1886 
was cropped with potatoes, 400 pounds of acid phosphate per acre 
being used. The yield was 129.2 pounds of merchantable, and 26.5 
unmerchantable, or 43 bushels of merchantable potatoes per acre. 
F 21 in 1884 was in pole beans, 400 pounds of fertilizer per acre 
having been used; in 1885, planted with squashes, no fertilizer being- 
used; in 1886, planted with corn, 400 pounds fertilizer per acre. The 
yield was 152.2 pounds merchantable corn, and 14.4 pounds unmer- 
chantable corn, or 38 bushels of merchantable per acre.
