THE LAND ROLLER. 
The land roller (Table VII) is an implement of relatively light 
draft, and two horses operate a wide range of width. Its limit in 
width is determined by the awkwardness of the larger sizes rather 
than by their draft. The table shows an increasing acreage with 
increasing width, although the increase in results is not in propor- 
tion to the increase in width.

GRAIN CROP OPERATIONS. 
From Table VIII it is seen that nearly all farmers in western New 
York use a grain drill sowing 11 rows, or a strip from 6 to 6 \ feet 
wide. With this size drill the grain and grass can be sown regu- 
larly, and in addition corn can be drilled two rows at a time, 42 
inches apart, or three rows at a trip, 35 inches apart. Beans can 
also be drilled 28 inches apart, sowing three rows at each trip. The 
daily acreage planted for drills having 9, 10, and 11 tubes is shown 
in the table.

Table IX gives the duty of the grain binder in western New York. 
Four-horse teams are seldom used in this section, and the smaller 
widths are often drawn by two horses. The 6-foot binder and three 
horses are most commonly used. The 7-foot binder is too heavy for 
three horses.

and 3 -horse teams.
