Scattering. 
The acres covered per day increases with the width of cast but not 
in proportion to it, those sowing the narrowest strips covering almost 
2 acres per day per foot of width, while the largest ones cover only a 
little over 1J acres per day per foot of width. For the seeders in 
most common use, those sowing strips from 30 to 35 feet wide, ap- 
proximately 50 acres is an average day's work. However, there is a 
considerable variation in the area covered by seeders with the same 
width of cast. 
GRAIN DRILL. 
The drills reported vary in size from the small 5-tube machines" 
drawn by one horse, used in drilling winter wheat between the rows 
of standing corn, to wide implements having 20 to 24 tubes. The dis- 
tance between tubes varies from 4 to 8 inches, but on nearly one-half 
of the machines they were 6 inches apart, and the 6 and 7 inch drills 
include three-fourths of the total number reported. Over 90 per 
cent of all the drills reported are disk drills. The average perform- 
ance of disk drills with 16 tubes 6 inches apart, drawn by four horses, 
is given in Table XX. There were not a sufficient number of reports 
on any other unit to give a reliable average.

The figures show that one man and two horses, with an end-gate 
seeder seeding a strip 35 feet wide, cover nearly three and one-half 
times as much ground per day as do one man and four horses with a 
16-tube disk drill. However, the broadcasted grain must be covered, 
and to complete the operation the ground must be gone over with 
either a spike-tooth or disk harrow in addition to the end-gate seeder.
