seen that the lot under consideration (which we take as a spec¬ 
imen for the whole farm), has now reached the fifth year in its 
course of rotation, having been the first and second years in 
clover, or clover and other grasses mixed; the third year in 
pasture; the fourth in corn and hoed crops, and the fifth in 
wheat. With land of ordinary quality, treated in this manner, 
the yield of wheat will usually average about 25 bushels per 
acre. There remains one more season to complete the course. 
For this, we plow the wheat stubble under as soon as practica¬ 
ble. If there is manure to spare after putting enough on the 
pasture lot, we spread it on that which is to be sown with the 
light grains, oats, barley, etc., and seed down. We prefer to 
sow grass seed before the last dragging of the field; never hav¬ 
ing met with a failure when sown in this way. Seeding im¬ 
mediately after the last dragging, is also a good method, pro¬ 
viding no heavy rain intervenes to pack the ground before it is 
done. Grass seed cannot be buried as deep as other grains; as 
a general rule, the larger the seed, the deeper covering it re¬ 
quires ; for this reason we do not approve of mixing grass seed 
with the grain in the drilling machine or the broad-cast sower, 
as much of it must be covered up so deep as to never come up. 
Where the ground is freshly worked, a good rain is sufficient 
to cover it, but when the rain precedes the seeding, the seed is 
liable to remain exposed on the surface, and to dry up and 
perish. 
For the next three years this lot is to remain in grass, being 
cut for hay the first two years and returning to pasture the 
third, or even the second year, according to the fancy or neces¬ 
sities of the farmer, and being broken up at the end of that 
period, is to go again and again through the course we have 
been describing. In this manner there will be constantly upon 
the farm, one lot in corn, potatoes, etc.; one in wheat; one in 
oats, barley and light grains, and three lots, or one-half of the 
farm, in grass. 
The manure we prefer to plow under with the breaking up 
of the pasture and with the plowing of the wheat stubble. 
Many persons spread their barn-yard manure on the surface of
