The relative value of the various fertilizers
of red in the market, is question Of ne little
interest to those who can not manufacture In
the barn-yard all the manure they need. The
trial detailed below, may be taken a. one of
the many experiments required to settle the
question fJr different Soils The land consists
Of between three and four acres; the frst
planting Of Msy 16, with the impros ed King
Philip Corn, was on sod land broken up two
weeks previously, and probably had never
been manured The second planting, Of May
23d, was on portion Of the same field, which
has been in potatoes for two years past. To
arising from variation in SOIL successive strips
Of three rows were taken for each fertilizer,
the same kind coming in moro than once The
ground was furrowed out with . small plow,
the ferdlisers scattered uniformly along the
burrows, and the corn dropped upon them, in
drills, and covered. We give the appearance
Of the corn from careful observations u sde

is usually recommended, because ws could nut

The Bone-dust was the fine crushed, but
coarser than the bone sawdust, which would
have been far preferable, If 1t could have been
obtained. 1t would average about the size of
peas. Cost about 81. so per barrel.
The Muck used was dug out last summer;
carted In during February, and mixed with
lime; and Faturatel with thin manure water

strong drainage u heap. The barn cellar
was about half full Of horse and COW manure,
litter and muck from the stalls, and the sink
slOps from the house. The breaking of an ad-
joining cistern filed up the cellar with water,
and this water after soaking the manure for
few days, was pumped out upon the muck. 1t
could hardly be called colored water, as at the
bottom pail was visible In Il at the depth of
seven inches. We state these particulars to
indicate the value of even dilute rain wash
ings from the manure heap, as shown on plot

The yard manure was q compost of horse
and COW manure, litter, muck, and cotton
seed.
