Notes.—VFirst killing frost 1890, September 13, a. m. 
The data for 1890 given in this table came to hand too late to allow of preparing the 
corresponding meteorological table-—C. A. June 30, 1891. 
MAIZE. 
INDIANA. 
From experiments in planting maize, made at the Indiana Agri- 
cultural Experiment Station (see Agr. Sci., Vol. III, p. 192), the 
following results were deduced : 
Planting on May 1 gave a loss at harvest of 5.47 bushels per acre; 
planting on May 21 gave a gain of 0.31 bushels per acre. 
Deep plowing in 1886 and 1888 gave an increase over shallow 
plowing of 2.4 bushels per acre, and 0.1 bushel in 1888. 
Deep culture with a cultivator of 3 to 4 inches gave better results 
than a shallow culture of from 2 to 3 inches. 
As to rate of planting or density of stand, two kernels every 
28 inches apart and three kernels every 36 inches apart seem to give 
the best results for hand planting. For machine planting, the best 
results were given with stalks 12 and 14 inches apart.
