On (he Rotations oj Crops on Heavy Lands. 
Third year — Clover, to be cut for hay, on one half, and trefoil 
and rye-grass mixed on the other half, to be fed off by sheep in 
the Spring, and followed by Spring tares, also to be fed off by 
sheep. 
P'ourth year — Wheat. 
Fifth year — Winter-beans. 
This ends the course, excepting that in the next course the 
clover takes the place of the trefoil and rye-grass in the former 
course, and the trefoil and rye-grass that of the clover, by which 
arrangement the land bears clover only once in ten years. 
By this system every hundred acres of arable land would pro- 
duce annually forty acres of wheat, twenty acres of beans, thirty 
acres of tares, twenty acres of turnips, ten acres of clover, to be 
mown twice, and ten acres of trefoil and rye-grass, to be fed a 
few weeks in the spring. 
In order to point out the fitness of the above rotation for the 
object intended, it will be necessary to enter into some particulars 
respecting the cultivation best suited for some of the crops. 
Preparation for the winter tare-crop should connuence before 
the beans are carried from the field. My practice is to cut them 
and bind them in sheaves at the end of July (for icinter beans 
will ripen thus early) ; I then clear a space wide enough for the 
ploughs to begin, and place the beans on the ploughed land as 
the ploughs proceed, and then, by arranging them in straight 
rows across the field, the land may be harrowed and rolled before 
the beans are ready to be carried, and another ploughing may be 
given immediately after, followed by the necessary harrowings 
and rollings. The field should then be manured with rough un- 
fermented dung : the less the manure is decomposed when ap- 
plied for this crop, the lighter and drier will the land be in the 
spring, after the tares are fed off, and the greater will be its effect 
on the following turnip crop. The tares should be sown for 
successional crops from the first week in September to the end 
of October ; a small portion of those sown first should have a 
little rye mixed with the tares — about one bushel of rye and two 
bushels of tares per acre would be sufficient : this would be ready 
for the sheep to begin early in the spring, and should be followed 
by wheat and tares, in the same proportions. A larger quantity 
of this may be sown than of the rye and tares, as the wheat con- 
tinues longer in perfection, as food for sheep, when mixed with 
tares than with rye ; and I have found it prove a very wholesome 
and abundant crop — one acre frequently producing sufficient food 
for two hundred sheep for a week, in the month of May. The 
winter tares should then be sown in the following order : — 
In the first week of September a small portion should be sown 
with rye and tares, and a larger portion with wheat and tares.
