to throw the locust into the interior of the cylinder, where they would 
become entangled in the tar and be poisoned by it. The machine runs 
on wheels whose axle is the axis of the cylinder. 
A correspondent of The Kansas Farmer, in the issue of June 6, 1877, 
describes the following contrivance: 
I yesterday put together a. machine which I do not propose to patent. It is con- 
structed as follows: I had riveted together two sheets of stove-pipe iron, each 2 by 7 
feet, making a surface of 4 by 7 feet. I rolled up the back side about 18 inches 
high, and held it to its place by nailing to it rounded inch boards. I turned up the 
front a trifle, and nailed to it a narrow strip of siding to stiffen the machine under the 
bottom, well back, so that it would balance. I fixed a three-eighths round iron for an 
axle, and fastened it by driving a staple over it near the ends and into the board end 
pieces. The wheels should be 16 inches in diameter, made of inchboards, three thick- 
nesses nailed together, so that the grain of the wood will cross. I push my machine 
with a handle made of half-inch iron, a piece 12 feet long, the ends flattened, and 
fastened to the end board with screws, the rod bent up and made the proper shape, 
so as to come about to the bottom of a man's vest when operating the " dozer." I 
cover the surface with tar (common), which will burn and is poison to the 'hopper. 
The machine tilts over the axle and can be made to scrape the ground or raised to 
pass over grain or obstructions. The " dozer" is a perfect success, gathers the 'hop- 
pers almost as clean as a reaper will cut grain; none get away. One week's work 
and 4 gallons of pitch tar will clean the worst 'hoppered 160-acre farm in Minnesota. 
At one priming with tar yesterday my man caught in about an hour a half bushel, 
estimated to make 10 bushels when grown. 
(4) Catching or Bagging. — "There are innumerable mechanical 
contrivances for this purpose, The cheapest and most satisfactory are 
those intended to bag the insects. A frame 2 feet high and of varying 
length, according as it is to be drawn by men or horses, with a bag of 
sheeting tapering behind and ending in a small bag or tube, say 1 foot 
in diameter and 2 or 3 feet long, with a fine wire door at the end to ad- 
mit the light and permit the dumping of the insects, will do admirable 
work. The insects gravitate toward the wire screen, and when the 
secondary bag is full they may be emptied into a pit dug for the pur- 
pose. Those bagging- machines will prove most serviceable when grain 
is too high for the kerosene pans, just described, and they will be ren- 
dered more effectual by having runners at distances of about every 2 
feet, extending a foot or so in front of the mouth, so as to more thor- 
oughly disturb the insects aud prevent them from getting underneath; 
also by haviug wings of vertical teeth, so as to increase the scope with 
as little resistance to the wind as possible." 
Two important facts should always be borne in mind in using these 
bagging-machines: First, that they should always be drawn, as far as 
possible, against the wind, if this be stirring ; second, that in proportion 
as the insects and the grain are advanced in growth, and the former be- 
come predisposed to roost, in that proportion the machines will prove 
more serviceable at night. 
We constructed a machine embodying the features already mentioned, 
and it answered the purpose very well indeed. The following account 
is from the Scientific American:
