wardly from the frame F. The flies E E consist of wire frames G G, covered with can- 

 vas H, and are secured to the front uprights of the frame F, which is also of wire. 

 Draw-flies 1 1 are hinged to the front standards of the frame F, and are connected wiih 

 the frames G G by spiral springs J J, which hold them open. 



The frame F has its top ends and rear side covered with wire-gauze. A tongue, K, 

 leads from the rear of the frame A, is supported at its rear end upon a caster- wheel, jL, 

 the shank of which i^enetrates the tongue K, and is provided with a foot-lever, M. A 

 driver's seat, N, resting upon a spring, O, is secured to the tongue at its rear end, in a 

 position to permit the driver to operate the f ^ot-lever M. A cord, P, connects the draw- 

 flies I I, and a cord, Q, attached to the cord P at its center, leads to a slot, R, in the 

 tongue K, where it connects with two cords, S S'. The cords S S' are secured, one to 

 each side of the frame T, in which the caster-wheel L has its bearings. Pins U U' are 

 fixed in opposite sides of the wheel L near its periphery. Metallic slats V are pivoted 

 longitudinally on the frame A, and are connected at one end by the rod W. A single- 

 tree, X, is secured to the tongue K, slightly ia front of th'j foot-lever M. The horses 

 are harnessed to the machine with their heads facing the frame A.

The operation of the invention is as follows : 



The slats V are left partially open, and the machine driven over the infested field. 

 The grasshoppers rise from the ground, and are drawn or driven into the frame F by 

 the draw-flies I I, which are closed every revolution of the wheel L by the pins U or 

 U' engaging with the cords S or S', as the case may be, both pins engaging when the 

 wheel L is straight, but only one when it is turned to either eide to guide the machine. 



The pins U and U' are beveled on their rear sides, and the cords S and S' slip from 

 said pins, when the pins are at the rear of the wheels and in line with the bearings of 

 the same, and permit the draw-flies to open by the spiral springs J J. 



The pins U U' and cords S S' may be dispensed with, if desired, and the cord Q may 

 be extended to the driver's seat and there operated by hand. 



When the space beneath the metal slats V in the frame A has been filledwith the in- 

 sects, the slats V should be closed, and the drawer D, previously supplied with sulphur, 

 opened, the sulphur ignited, and the drawer closed. The fumes of the sulphur will 

 destroy the grasshoppers, after which the machine may be cleaned and the operation 

 repeated. 



The Sylvester Locust-catcheu. 



Another contrivaDce was invented by Mr. Benjamin Sylvester, of 

 Saint Peter, Minn, (patent No. 188,7G0, dated March 27, 1877), of which
