part of a saddle as well as to any cart. Plate LYII, Fig. 5, is a front 

 view of this contrivance, and Fig. 6, a side view of the same, partly in 

 section through one of the cylinders. 



"AA are two cylinders, formed by attacliing fiue wire-gauze or finely-perforated sheet 

 metal to circular ends or disks. To the inner surfaces of the cylinders A are attached 

 longitudinal strips, B, to one side of each of which is attached a strip, C, of tin or 

 other suitable sheet metal, which strips thus form flanges, which, as the cylinders re- 

 volve, raise the compound and allow it to fall back so as to keep it stirred up and 

 prevent the heavier ingredients from settling and thus escaping in too large a propor- 

 tion and unevenly. The cylinders, A, are placed upon the end parts of a shaft, D, 

 and are secured in jjlace adjustably by keys or nuts, so that they may be moved to- 

 ward or from each other to correspond with the distance apart of the rows of plants. 

 Upon the middle part of shaft, D, is formed a crank, d', by means of which the cylinders 

 «ire revolved, either by taking hold of the said crank, d', directly, or by a short handle, 

 I], pivoted to said crank. The shaft, D, revolves in eyes in the upper ends of two bars, 

 F, the upper parts of which are curved to give room for the crank, d' y to operate. The 

 Oower parts of the bars, F, are parallel with each other, and pass down upon the oppo- 

 site sides of the standard, G, to which they are secured by a bolt, H, which passes 

 through a hole in the lower parts of the said bars, F, and through a slot in the said 

 ■standard; G, so that by loosening the hand-nut, /i', of the bolt, H, the cylinders, A., may 

 he raisf d and lowered, as the height of the cotton-plants may require. 



"The bars, F, maybe kept from turning upon the bolt, H, by lugs formed upon the 

 anner sides of the bars, F, which enter the slot of the standard, G, or by a second bolt. 



" The lower end of the standard G is branched, and has screw-holes formed through 

 said branches to receive the screws or bolts by which the machine is secured to the 

 forward part of a saddle, or to the frame of a sulky. 



'• The Taylor Dusting and Sprinlding iliac/iiwe.— Another machine, in- 

 vented by Mr. Thomas B. Taylor, of Mount Meigs, Ala. (patent No. 

 214205, April 8, 1879), is somewhat similar to the Eobinson machine 

 ;already described in that it has arrangements for both sprinkling liquids 

 .and for dusting powders, and both can be used simultaneously or each 

 separately. The dusting apparatus does not differ materially from the 

 perforated revolving cylinders already described, but the machine is 

 interesting because it is to be attached to a common plow-stock, so as 

 to do the cultivating and the poisoning at one and the same time. Plate 

 LVIII, Fig. 6, is a vertical longitudinal section, and represents the plow- 

 ;stock with both the sprinkling and dusting arrangements attached to 

 ithe same. 



"A represents the beam, B the handles, and G the standard of an ordinary plow- 

 stock. To the forward and rear parts of the beam, A, are rigidly attached two stand- 

 ards, D, the rear one of which maybe the upward extension of the plow-standard, C. 

 The lower end of the forward standard, D, extends to or nearly to the ground, and 

 has a plow-plate, E, attached to it to assist the plow-plate, F, attached to the plow- 

 standard, C, in cultivating the ground, and to give steadiness to the machine, so that 

 it may be readily controlled. To the upper parts of the standards, D, are pivoted the 

 centers of the long front and rear bars of the rectangular frame, G, to the centers of 

 the short side-bars, of which are pivoted the ends of the sheet-metal cylinder, H. 

 This cylinder represents the sprinkler, and a more detailed description of it will be 

 given under the proper head. It can be detached, and the dusting arrangement, 

 which, in the figure, is represented as secured to the rear of the frame, G, can be put 

 in its place. This dusting arrangement consists of a frame, O, similar to G, and to it
