E. SINCLAIR Jr. & CO’S PATENT CORN MILL—(Fig. 2.) 
The machine represented by the above cut, is admira¬ 
bly adapted to plantation use. It makes coarse or fine 
meal with equal facility, at the rate of two and a half to 
three bushels per hour. When the screen is attached, 
(as shown in the centre of the cut,) 
and fine meal is required to be ground, 
it will be necessary to drive the mill 
by horse power, say two horses. 
Coarse meal for horses, may be 
ground by two men with good suc¬ 
cess. The grinding plates are made 
of the hardest composition metal, and 
will last about two years. A feeder 
Fig. 4. is attached to the axle, which is in¬ 
tended to pass the grain into the plates at regular inter- 
a vals. This feeder is important, and obviates the 
objection to cast iron mills generally. The 
feeder and grinding plate are represented se¬ 
parately from the mill, in figs. 3 and 4. Price 
of the mill with a set of extra plates, $40. Ma- j

EXPERIMENTS IN THE CULTURE OF INDIAN CORN. 
We are indebted to our friend Geo. Geddes, Esq., of 
Onondaga county, for the following detailed account of 
several experiments made by him, with great care, the 
past season, in the culture of Indian Corn. They will be 
read with interest, and our readers will be glad to learn 
that these experiments will be continued with the same 
exactness the ensuing season. Mr. Geddes says: 
The Soil is a deposit of gravel mixed with sand and 
clay, resting upon a gypseous shale. The previous 
course of cultivation has been as follows, viz:—In 1837, 
a crop of corn was raised on a heavy sod turned under 
that spring, and slightly manured with barn-yard manure. 
The yield was estimated at 65 bushels to the acre. In 
1838, corn was again raised, and without any manure; 
estimated to yield 50 bushels to the acre. In 1839, it was 
sown with oats, and yielded a very heavy crop. Grass 
seed was sown with the oats, which succeeded well. The 
next four years it was pastured. Plaster was put on both 
corn crops, and on the oats, and once or twice on the 
pasture. 
The ground was plowed about the first day of May, 
six inches deep, and planted on the third and fourth days 
of that month. 
The variety of corn was the improved Dutton; that is, 
Dutton that had been selected from the earliest ears for a 
series of years. 
Experiment No. I. 
One acre was planted in hills three feet apart each 
way, six kernels in the hill. Fifty loads of half rotted 
manure, was put on this acre, after it was plowed, and 
harrowed in as well as it could be done; it being so 
coarse that it piled up a great deal before the harrow. 
The hills had a hoe full of tl best of the manure drawn 
in by the planter, and the coon dropped into it. It was 
hoed twice, and a cultivator was run once along each row 
both ways , at each hoeing. The account of the cost of cul¬ 
tivation, is as follows, viz: 
To plowing and harrowing one acre,.$1-50 
50 loads of manure, drawing and spreading,. 1:2*50 
2 days work of one mar- planting, • • .. 1*60

The product was 70^ bushels—at 4s=$35.25—20.88 
=$14.37, for the use of the land; or the corn cost, be 
sides the use of the land, $0.29,6 per bushel. 
Experiment No. II. 
The other acre was cultivated as follows—One-tenth 
was planted in hills three feet by two feet apart, six leer 
nels in a hill, and without any manure. The account of 
the cost of cultivation is as follows, reduced to acres. 
To plowing and harrowing one acre,.$1*50

$9*12 
The product was sixty and one-quarter bushels to the 
acre, at 4s=$30.12—9.12=$2l.00 for the use of the 
land; or the corn cost, besides the use of the land, $0.15,1 
per bushel. 
Experiment No. III. 
Another tenth was planted the same distance apart, and 
the same number of kernels in the hill as the last—and 
was manured, by filling each furrow, as it was plowed, 
full of barn-yard manure, unfermented —the amount used 
being at the rate of 150 loads to the acre. The cost of 
production was as follows, reduced to acres: 
To plowing and harrowing one acre,.$1*50 
2 men to fill the furrows with manure,. 1*50 
2 days work planting,. 1*50

$29*37 
The product was seventy bushels to the acre, at 
4s=$35.00—29.37=$5.63 for the use of the land; or 
the corn cost, besides the use of the land, $0.42 per 
bushel. 
Experiment No. IV. 
Another tenth was the same distance apart, and the 
same number of kernels in the hill as the last, and manu¬ 
red with coarse manure in the same way, and had beside, 
a top dressing of half rotted manure, at the rate of twen¬ 
ty-five loads to the acre. The cost of production was as 
follows, reduced to acres: 
To plowing and harrowing one acre,.$1*50 
150 loads of coarse manure,. 18*75

The product was eighty bushels to the acre, at 4s— 
$40.00—36.37=$3.63 for the use of the land; or the 
corn cost $0.45,5 per bushel, besides the use of the land. 
Experiment No. V. 
Another tenth was planted in drills, three feet apart, 
the corn four inches apart in the drills. It was manured 
with 25 loads of half rotted manure, to the acre, put on 
after the plowing. The cost of production was as fol 
lows, reduced to acres: 
10 plowing and harrowing one acre,.$1*50
