part of a saddle as well as to any cart. Plate LVII, 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 attaching fiut; 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, 
aud are secured iu place 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 
are revolved, either by taking hold of the said crank, d' f directly, or by a short handle, 
E, pivoted to said crank. The shaft, D, revolves in eyes iu the upper ends of two bars, 
F, the upper parts of which are curved to give room for the crank, d' t to operate. The 
lower 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 <\he lower parts of the said bars, F, and through a slot in the said 
standard. G, so that by loosening the hand-nut, li', of the bolt, H, the cylinders, A, may 
be rais d aud lowered, as the height of the cottou-plants may require. 
"The bars, F, maybe kept from turning upon the bolt, H, by lugs formed upon the 
inner 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 Busting and Sprinkling Machine. — Another machine, in- 
vented by Mr. Thomas B. Taylor, of Mount Meigs, Ala. (patent Xo. 
U14205, April 8, 1879), is somewhat similar to the Robinson 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. G, is a vertical longitudinal section, aud represents the plow- 
stock with both the sprinkling and dusting arrangements attached to 
the same. 
"A represents the beam, B the handles, and C 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 may be 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 
(•enters of the long front aud rear bars of the rectangular frame, G, to the centers of 
the short side-bars, of which are pivoted ihe ends of the sheet-metal cylinder, II. 
This cylinder represents the sprinkler, and a more detailed description of it will ho 
given under the proper head. It can be detached, and the dusting arrangement, 
which, in the figure, is represented ;is 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
