vided with distributing faucets arranged upon both ends of the frame, 
the one balancing the other, and one or both at the same time may be 
operated by the rider. 
''In Plate LVT, Fig. 1, iii tlie cut is an end view of the machine ; Fig. 2 ia a piano 
yiew, and Fig. :> is a side view of the same. 
"A A' designate, respe cti vely, the front and roar bars of the frame, connected to- 
gether on each side by means of a platform, C, upon which are to he placed oil-cans, B, 
or other convenient vessels for the reception of the destroying compounds. These ves- 
sels art' removably secured t hereto in any suitable manner, and their outer lateral 
edges are each provided tritna distributing stop-cock, I), having a on acei)t-sBaped per- 
forated nozzle-pieee, (J. by means of which the liquid poison will be shed over a wide 
•pace. The front bar, A. has an angular notch, E. cut into its lower edge, near the apex 
SS* which, ami one eaeh side thereof, perforations, e, are made by means of w ich it is 
secured to the pommel of the saddle. It is also provided with perforations, <•', upon 
its lower edge, by means of which it is laterally stayed Wy a rope passing tlienee to 
the girth-rings on each side of the saddle. The rear bar, A', is in like manner Botched 
as shown in Fig. 2, ami is provided with a slot./, at ihe apex of its notch, by means 
of which it is strapped to the cantle of a saddle, and with perforations, f } along its 
lower edge, serving as a means of attachment for a rope, passing thence to the girth- 
ling! on each side. 
" It will be seen from the above descript ion that the frame is firmly attached both to 
the pommel and cantle of the saddle, and that it is btnoed and steadied to resist dis- 
placement by ropes or straps lending from the perforations, 4 and / ', upon the front 
and rear ban of the frame, respectively, to the girth-rings on each side of the saddle, 
eonstitnting a simple, convenient, and effectual attachment for the purpose of pre- 
venting any displacement. The notches of the front and rear bars, A A', are intended 
to be Straddled OVei that portion of the ped-franM of S saddle which projects in front 
of the pommel thereof, and extends in rear of the cantle, the rider being seated be- 
tween the two, with a poison-receptacle on each side, with their stop-coeks within 
easy reach of his hand. lie can thus accurately regulate the flow of poison accord- 
ing to the amount required to effect the purpose, the movement of the horse serving 
materially to assist the distribution. 
"The Ramsey Sprinkler. — Mr. Oroghan A. Ramsey, of Schalenbnrg, 
Tex., has obtained a patent (No, 163528, May 18,1875) for the very 
simple contrivance which is illustrated in Plate LVf , Fig. 5. It con- 
sists of a box or vessel, A, large enongh to hold about Ave gallons. Tt 
is provided at its top with a receiving funnel, a, lor the liquid. At the 
bottom or on the front side near the bottom, and near each end, are two 
flexible tubes or rubber hose, B, provided with nozzles, b. This device 
is intended to be strapped upon a horse's back, to the cantle of a saddle, 
with the tubes in front. The front of the vessel, A, is inclined backward, 
so as not to interfere with the movements of the rider ; and a pad, ( !, may 
be placed under it, so as to cause it to rest easy upon the horse. The 
nozzles, when not in use, are held above the top of the box by means of 
hooks, c, which seize over rings, upon the top corners of the box, so 
as to prevent the liquid from flowing out. When in use the rider takes 
a tube iii each hand and proceeds to sprinkle the rows on each side. 
Knapsack Automatic Sprinklers. — A number of these have 
been in use, and the following examples from the first edition of this 
work illustrates these devices sufficiently :
