Grasshopper Control 
T T 
very inexpensive and convenient hopper dozer (Plate I, Figs. 3 
and 4), which may be operated with one horse. The plan is such 
that any farmer should be able to construct it for himself. 
The pan was made by nailing a sheet of 24-gage galvanized 
roofing iron, 30x96 inches, to a frame, 24x96 inches, made of two- 
by-fours. Three inches were allowed to turn up on either side of 
the frame to make the pan more secure. A strip of candle wick- 
ing was nailed beneath the iron between two rows of nails, to pre¬ 
vent leakage. The ends of the pan were bolted to runners made 
of 2 inch x 10 inch strips, 4 feet long, and at either end of this 
runner was a small cast iron 10-inch wheel. The object of the* 
wheel was to steady the pan over rough places and to lighten the 
draft-of the dozer. The pan was supported on runners about four 
inches above the ground and the wheels supported the runners 
about half an inch. A light frame, 3 feet high, covered with oil¬ 
cloth, was fitted to the back of the dozer with the smooth side in 
front. The bottom of the cloth was tacked to the inside of the 
pan, and the framework was braced in front of the runner. 
The material and cost of building the dozer, according to Mr. 
Blinn, was as follows: 
vr 
One sheet of No. 24 galvanized iron. 23 lbs., 92.$2.07 
One piece of 2x4, 16 ft. 
One piece of 2x4, 8 ft. 
One piece of 2x10, 8 ft. 
One piece of 1x4, 16 ft. 
Total—32 ft. at 2y 2 c.95 
Three yards of table oilcloth at 18c.54 
Four cast wheels .50 
Bolts, nails and rope.40 
One ball of candle wucking.10 
Total cost.$4.56 
By hitching a horse in front to one runner, and having a rope 
from the other runner attached to the hame staple of the harness, 
the dozer, by the aid of the wheels, may be dragged at right angles 
and to one side of the horse, thus preventing the hoppers from 
being frightened away from the advancing pan. 
Balloon Catcher .—The “balloon” hopper catcher consists of 
a light frame of wood twelve feet long and two feet high, to which 
is attached a bag about eight feet long, the framework forming 
the mouth of the bag. The apex is open, but, when in use, tied 
with a string. The apparatus is drawn by a single rope which 
forks and re-forks, sending a branch to each corner. The draw 
rope is fastened to the single-tree of a light harness or to the 
pommel of a saddle. In dragging this sack over the infested areas
