REPORT UPON COTTON INSECTS. 



The object of making the spout inclined, as shown, is to enable it to discharge 

 either up or down, or on either side, as desired, without changiug the position of the 

 bellows D, the change being effected by merely turning the reservoir around on the 

 nozzle m of the bellows until the spout is pointed in the proper direction. 



The reservoir A is divided in the present instance by two longitudinal partitions, i 

 i, which break up the contents of the reservoir and prevent them from accumulating 

 in the lower portion of the same openings jj, liowever, allowing such communication 

 as will permit the entrance of sufficient material into the lower portion of the reser- 

 voir to supply the place of that expelled at each blast of the bellows, thus insuring an 

 even discharge of the whole contents of the reservoir. 



In order to cause the air to act only on the portion contained in this lower division, 

 the nozzle has an inclined face, 11, in which the perforations for the escape of the air 

 are formed, the air being thus directed against the bottom of the reservoir, and carry- 

 ing with it a small quantity of the contents, which are expelled through the spout a. 

 A perforated disk, x, is inserted into the entrance of this spout, to assist in distribut- 

 ing the contents evenly. 



This machine has been largely used for the potato-beetle and for 

 green-house work. It was invented when people were much afraid of 

 handling Paris green ; of late it has been used but little, as it is worth- 

 less for distributing bulky compounds like Hogal's patent and others 

 now used. It may be found that much less bulky compounds will an- 

 swer as well ; in which case there will be a demand for a machine of 

 this kind. 



Mr. W. T. Willis, of Brenham, Tex., has also invented a machine for 

 the purpose of distributing dry poison upon the plants. This machine 

 is adapted to be secured across the front part of a saddle and to be oper- 

 ated by the rider. 



Ko. 2 in the accompanying figure is a sectional view of the machine. 

 No'. 3 is a detail view. 



A A designate two boxes of any suitable capacity, which are constructed with two 

 fixed sieves, p p, and movable sieves p', arranged between the fixed sieves and sup- 



ported upon rods, so as to elide 

 freely when the boxes are vi- 

 brated, and aid in pulverizing the 

 material, and at the same time 

 scattering it uniformly. The 

 upper sieves p will support the 

 bulk of the material free from 

 the scattering-sieves p 1 . Each 

 box has secured to it a suspen- 

 sion-standard, B, having a num- 

 ber of holes, a, through it, ar- 

 ranged one above another, and 

 adapted to receive suspension- 



pins ft c, and allow the boxes to 

 be adjusted vertically for high or 

 low plants. C designates a bar, 

 from which rises a guide-rod, C'. This bar C is intended to be secured by the middle 

 of its length to a riddmg-saddle in front of the rider, and through its ends holes are 

 made, through which the standards B B are passed, and sustained by means of the 

 pins c c. Supplemental holes are made through the bar C, to allow the boxes A A 

 to be adjusted for rows of plants varying in -width. D designates a bar, the ends of 



No. 2.
