at the end to let out the insects collected. A boy 10 years old can draw one end of 
this net, and by the use of it, Major Thompson saved one piece of wheat. 
Mr. J. 0. Elliot, of Sheldon, Iowa, thus describes a rnachiue of his own 
devising that was much liked in his section: 
Take a strip of pine lumber 1 inch thick, 2 inches wide, and 10 or 12 feet long; 
about 18 inches from each end mortise in a strip about 2 feet long of the same mate- 
rial as your main piece ; run a strong wire from one end of the main piece over the 
ends of the two upright pieces and fasten to the opposite ends of the main strip, form- 
ing the framework to the mouth of your dozer. The wire should be permanently 
fastened to the top ends of the upright pieces to form a brace to keep them always in 
place. Place the long strip of lumber on the ground so that the standards stand per- 
pendicular; take two widths of strong cotton cloth the length of your main strip 
sew them together so you will have double width, tack one side of the cloth to the 
long wood strip ; this forms the bottom. Take of mosquito-bar enough to form a top 
to the net, fastening one side to the wire running over the top of the standards ; put 
in such gores of cotton cloth at the ends as you may need to form a complete sack of 
the cotton cloth and mosquito-bar. A good plan to facilitate taking out the 'hoppers 
when caught is to let the back part of the net run to a point in the center, and leave 
a small opening, which can be fastened with a string while at work, and unloosened 
to empty out the 'hoppers. The object of the mosquito-bar is to allow the wind to 
pass through and keep the 'hoppers in the net. 
A very successful method of catching pupae was used by Mr. Lowe 
and Mr. Hall, farmers, in McLeocl County, Minnesota. It is simply 
equivalent to a wagon-body with one side removed, to be drawn over 
the grain after dark. The locusts roosting on the grain fall into it, 
simply lie there and become entangled in a mass, and may be easily 
shoveled into a hole. Mr. Hall thinks he caught 800 bushels in the 
latter part of June ; Mr. Lowe, 400. 
While in Iowa we inspected one of the following machines, which 
was not in working order, however, at the time, nor was it much used, 
even in the locality where invented. It is patented by Mr. George S. 
Wilson, of Malvern, and Mr. John Ehode, of Tabor, Iowa (patent Kb. 
192,553, dated June 26, 1877), and is described below. (PI. XI, Fig. 1.) 
a a represents two driving-wheels, upon which the machine is propelled about bya 
person or persons pushing from behind on the handle e. The frame consists, prefera- 
bly, at each end of the two curved timbers fZ, as shown, between which is clamped a 
curved sheet-metal plate, e, which forms the floor of the machine. Secured to the 
inside edge of the top timber, at each end, is a curved plate, g, which forms a flange 
along each end of the machine, in order to prevent the insects from being swejDt or 
jumping from the floor. 
To the rear edge of the floor is secured a box or receptacle, i, as long as the floor is 
wide; into which the insects are swept whole by the reel h. The cover of this box 
does not quite reach to the forward edge, thus leaving the space 1, through which 
the insects fall into the box. The upper end of the lid is turned backward a consid- 
erable distance, so as to form the flange 2, thereby preventing the insects from being 
swept back past the floor and opening 1 upon the ground behind. 
Extending across the front edge of the machine is a board or bar, n, sharp at its 
front edge, and the ends of which project beyond each side of the frame, and serve as 
a support for one of the three braces or standards 3, upon the tops of which the reel 
isjournaled, and operated by the belt or chain 8 over the pulleys 9. The axles 5, 
upon which the wheels a are placed, have their inner ends made U sna P e d, so as to
