d seldom extends beyond June 1st. If
prolonged unduly and dry weather follows, the growth of the plants will
not be enough to produce average crops of seed. Quite frequently on
upland soils, the grazing should cease before the end of May.

Either cattle or sheep, or both, may be used in the grazing. Cattle do
not graze quite so closely as sheep, which is so far favorable to
subsequent growth. But sheep will glean weeds to a much greater extent
than cattle. When the field is made to carry so much stock that the
grazing is quickly and thoroughly done, the results are usually more
satisfactory than when the opposite method is practiced.

It is important that weeds shall be prevented from maturing seeds in the
clover. To prevent this, it may be necessary to run the mower over the
whole field at the close of the grazing season. In crops that are not
grazed, it may be necessary to use the scythe in clipping back weeds and
in cutting off any stray heads of timothy that may be pushing up toward
maturity. In some instances it may even be found profitable to use the
spud in destroying weeds of more dwarfish growth than those which can be
clipped with the scythe. It is more important, relatively, that weeds
shall be thus dealt with in growing alsike clover than in growing clover
of the larger varieties, since, owing to the small size of the seeds of
alsike, it is more difficult to remove foul seeds with the winnowing
mill. No kind of seed, probably, is more difficult to separate from
alsike seed than timothy; hence, when the former is grown for market,
these plants should not be grown together. If, perchance, they should be
so grown and the crop cut for seed, it would be well not to try to
separate the seeds, but to sow them thus, as even when thus mixed the
seed has a considerable market value.

The crop is ready for being harvested when nearly all the heads are
fully matured. The bloom will then have left them and they will be
characterized by a reddish cast. The earlier heads will have turned a
dark color, almost black. Some bloom may yet linger on the later and
smaller heads, but harvesting should not be delayed until these mature.

The seed crop can best be cut with the self-rake reaper, which throws
off the sheaves unbound. If cut with the grain binder, the sheaves
should not be bound. A sort of box attachment may be fastened to the
cutter-bar of the mower, which will enable the workmen to leave the hay
in sheaves, but to
