Another machine that may be mentioned in this connection is that 
invented by Mr. Charles Hoop, of Arago, Nebraska (patent No. 187,155, 
dated February 27, 1877). In the accompanying illustrations, PI. n, 
Fig. 4, represents a top view of the machine; PI. n, Fig. 5, is a vertical 
section of the same taken through the line x x ; and PI. in, Fig. 1, is a 
side view. 
I witnessed the working of a machine invented by Mr. T. K. Hans- 
berry, of Padonia, Kansas (patent No. 188,359, dated March 13, 1877), 
intended to crush the insects by means of movable wooden bars. It 
does not prove very successful, however, except on the very smoothest 
ground. PI. in, Fig. 2, is a top view, when mounted on wheels or run- 
ners ; PI. in, Fig. 4, represents the front. PI. ill, Fig. 3, is a sectional 
view of the machine when on runners, with knives or bars attached ; 
and PL in, Fig. 5, shows the slide attached, close to the axle, to close 
the angle formed at the side by the ground and the knives or bars when 
the machine is mounted on wheels. 
Mr. Elisha Ken worthy, of Walnut, Iowa, has invented a machine 
(patent No. 186,970, dated December 5, 1876) which can be placed un- 
der this class of machines. PL in, Fig. 7, presents a vertical section 
of the invention, and PL in, Fig. 6, a plan view of the same. 
Numerous communications upon this subject have been received, 
some of which, if not all, are or may have been successful on a small 
scale. Others, if carried out, and the contrivances built and given a 
fair trial, mieht be of especial benefit. 
Mr. J. 0. Melcher, of O'Qumn, Tex., constructed one which he de- 
scribes as follows : 
It is constructed on the Laud lawn-mower style, mounted on light wheels, a disturb- 
ing rim, 8 or 10 feet long, passing low over the ground to stir the 'hoppers up. Just 
behind the disturber are two sheet-metal rollers, one of which drives an endless band. 
As soon as the 'hoppers jump over the disturber, the band catches them and crushes 
them between the rollers. The rollers, being of sheet-iron, are elastic enough to press 
uniformly at any given point. A rack of wire web or cloth ascends over the top of 
the machine to prevent the 'hoppers from escaping. It is operated by two men push- 
ing the machine before them. 
Mr. John Wise, of Nebo, Platte County, Nebraska, says (in a letter 
dated May 26, 1877) " a good machine can readily be made by having two 
revolving rollers mounted on wheels, the rollers to be 4 or 6 inches above 
ground, so arranged, if need be, to be adjusted either higher or lower, 
the upper to revolve on the top of the lower," etc. To a contrivance 
of this sort handles could be attached for pushing, and, with the addi- 
tion of a frame covered with cloth or muslin, projecting forward and 
outward. 
In addition to the preceding contrivances for crushing locusts is one 
invented by Mr. F. Peteler, of Minneapolis, Minnesota. 
PL iv represents a front view, and PL v, Fig. 1, a side view, of the 
same machine. 
In a communication from the inventor, dated June 8, 1877, the follow-
