which would be in meadow, one in oats, and one in corn 
each year. Thefollowing year the corn or potatoes would be 
upon the fall plowed meadow which had Jain two years, the 
oats on the corn ground of the previous year, and the oat 
field which was seeded down would bein meadow. And so 
on until the fifth year would see the crops on the same fields 
as at first. This general principle can be modified in count- 
less ways to meet different conditions. One way is to have 
two sets of fields on which 1 otations of different lengths are 
practiced. apa 
To illustrate this principle of perfect rotations, a set of 
eight plots was laid out in 1900 on good soil, and two 
rotations were started, a three year and a five year. In this 
case it took but one year to bring the proper crop upon the 
proper fields so that in the second year of the rotation, each 
crop was where it belonged. The five year rotation was 
cornfodder, for which the land was manured, then wheat 
seeded down, meadow two years, then oats followed the 
sixth year by cornfodder, thus beginning the rotation again. 
The three year course was oats seeded down, clover with the 
second crop plowed under, and potatoes the third year on 
TABLE CXII.—Showing the order of Cropping Eight Plots brought under a Five 
Course and Three Course Rotation.
