DESCRIPTION OF DRILL HARROW, 
For planting Seeds, and applying Manures, such as Poudrette. Bone-dust, Ashes, Plaster, Marl, fyc., at 
the same time. 
A. Main Wheel, to propel the machinery and roll in 
the seed; made concave in order to press the earth to 
the sides of the seeds as well as upon the top of them. 
It leaves a slight convex ridge upon, and a little furrow 
on each side of the seed, so that rain may settle at the 
sides rather than immediately upon the seeds. 
B. Regulating Wheel, to keep the Coulter at an 
uniform depth—made fluted to help pulverize the earth. 
C. Harrow, to throw aside small obstructions, as 
also to fine the ground. 
D. Seed Box, which may be drawn out for the pur¬ 
pose of emptying it. 
E. Tightening Pulley, to accommodate the band to 
such groove on the gearing wheel F, and on the head 
of the elevator, as may be necessary to give the re¬ 
quisite speed to the elevator or dropper, secured by a 
thumb screw underneath. This screw must be loosened 
to shift the elevators. 
F. Gearing Wheel, with grooves of different diame¬ 
ters, by which greater or less speed is given to the 
dropper -, of course, putting in the seeds at greater or 
less distances apart. 
G. H. I. Elevators or Droppers, of different sized 
holes, for corn, beets and turneps. 
J. Clearer, of whalebone, secured by a wedge in the 
frame of the elevator, just so as to spring into each 
hole as it passes the guide tube U. 
K. Leader, by which the seed box may be supplied 
without stopping the machine. 
L. Manure Box, or Hopper. 
M. Rack Wheel, connected by a band with gearing 
wheel F, and giving motion to shoe O, by connecting 
rod P ; this may be raised or lowered by slides and 
thumb screws under it, on the hopper. 
N. Slide Guage, to regulate the quantity of manure 
to be delivered. 
O. Shoe to hopper. 
P. Connecting Rod, conveying motion to shoe 0, 
from rack wheel M. 
Q. Gearing Rod, which upon being drawn, by 
pressure of the left hand upon chain Y, throws the 
gearing free from main wheel A. 
R. Pall, to prevent a reverse motion to the machine¬ 
ry j also serves to clean the surface of main wheel. 
S. Clevis. 
T. Coulter, which by nuts may be set deeper or 
more shallow, according to the desired depth for plant¬ 
ing different seeds. 
U. Guide Tube, conveying seeds to the furrows. 
Y. Chain for covering seeds, attached to knobs 
on the outside frame, so as to draw in a curved fofm 
after the coulter, and before the main wheel. 
W. Chain covering the manure upon the same prin¬ 
ciple as Y. 
X. Spring, acting upon the gearing wheel to keep 
it in its place when liberated. 
Y. Hand Chain, by which to move gearing wheel. 
Z. Hook, to retain hand chain, and keep the machi¬ 
nery out of gear. 
a. Leather Strap, to confine guide tube, 
b. Band to elevator or dropper. 
d. Band to manure dropper. 
e. Legs, resting on hooks when the Barrow is mov¬ 
ing, and extended when standing still, to keep it from 
falling on its side. 
The prevailing practice in that part of New-dersey 
to which I removed in 1833, was, to plant corn in hills 
about six feet apart each way, manuring only in tb$
