and the receptacle,/, will run ou the ground between the rows#» As the apparatus is 

 drawn forward the plants pass beneath the bar, h, one row at each side of the bar, h, 

 and pan, /, and the rows will be gathered together and bent down beneath the wings. 

 The flap]3ers will shake the plant and the larvae will be rubbed and shaken off into 

 the receptacle. 



The Iske Siveeper and Stifler. — '' This was patented by Mr. Anthony Iske, 

 of Lancaster, Pa. (No. 173728), in 1876. 



"It consists of an upright frame, open beneath, with two wheels in 

 front, and is drawn over one row of plants at a time. A row of brushes, 

 made of broom-corn or of anj other suitable material, is fastened to a 

 longitudinal beam, which is adjustable to the height of the plants and 

 agitated by a contrivance similar to that in Mr. Ewing's machine. The 

 worms dislodged by the action of these brushes fall in two canoe-shaped 

 trays, which are supported by swinging arms, and slide aloDg one on 

 each side of the row of plants close to their base. On the outer side of 

 each, these trays are provided with a smooth inclining shelf, which dips 

 into the tray, and with a vertical backboard in order to prevent any 

 worms from being beaten beyond these trays. In using this machine it 

 is necessary to smear the trays with tar or coal-oil." 



Other Catching-trays,—''' Finally, having proved that the least touch of 

 kerosene is as fatal to the cotton worm as it is to so many other insects, 

 I have no hesitation in recommending as a cheap substitute for these 

 brushing-machines, where youthful labor is abundant, the use of sheet- 

 iron pans, over the bottom of which kerosene or coal-tar is spread. They 

 proved very successful in 1877, when the Western farmers were con- 

 tending with young locusts ; and, drawn between the rows of cotton, 

 while the worms are being brushed off in the manner recommended by 

 Mr. Hoyt, they would prove equally satisfactory when the weather is 

 not sufficiently hot and dry to insure the death of the worms otherwise. 

 Or a still simpler arrangement might be adopted, viz : a cloth stretched 

 on a frame that will draw between the rows and kept saturated with 

 kerosene." 



TRAPS POR THE MOTHS. 



While the foregoing devices aim at destroying the pest in its earlier 

 stages, these are specially for capturing the parent forms — the moths. 



The moths are attracted in three ways: I. By lights which have on 

 -them an alluring effect ; 2. By odors associated with the sweets of 

 which the.v are fond, and 3. By both of these attractions combined. The 

 causes of this attraction and other points connected with it have already 

 been discussed in chai^ter XII, so we shall pass to the discussion of the 

 various traps invented. 



Light traps. — ^^The following enumeration of lamps for attracting 

 and killing the moth is by no means a complete one. Some of the inven- 

 tions are no longer used, and descriptions or samples of them unattain- 

 able ; others are mere copies of such as ai e here described, and are
