272 REPORT 



exteusion bearing a nozzle, to be held in one band. This nozzle is 

 described on page 209, (see Plate XIX, Figs. 6 and 7!) As a cheap pump 

 extensively advertised it has had a good sale and given considerable 

 satisfaction. The " Combination Pump " made in brass, retails at 85.50. 

 A hook is provided for attaching the base of the pump, but, as in other 

 pumps of this class, generally there is wanting some better means of 

 support to sustain the cylinder in an upright position and so leave the 

 left hand free to hold and direct the nozzle, while the other handworks 

 the piston. 



The sketch in Plate XLI, Fig. 2, represents a pump-support, pat- 

 ented in Xo. 124593, March 12, 1872, by Mr. C. G. Korth, of Carlstadt, 

 N. J., and shows an attempt to supply in pumps of this class something 

 to make their use more convenient. It consists of a crutch attached to 

 the pump and serving as a fulcrum for its lever. The top is held firmly 

 in the arm-pit while the sharp pointed base of the pump presses against 

 the bottom of the bucket, barrel, or other receptacle for the liq uid. This 

 leaves one hand, free to hold the nozzle. The other features of this 

 pump appear in no way novel or superior, but the inventor controls the 

 use of his support in pumps of all kinds. 



The folloicing buclcet-jmmps and Tcnap sack-pumps^ ichich are occasionally 

 offered hy the trade, seem not the most desirable for poisoning the crop, 

 though some on the list are well suited for other purposes and some ex- 

 hibit features which may be hereafter combined in the pumps which 

 are best adapted for our xmrpose. 



In patent Xo. 212067, February 4, 1879, Mr. A. Stoner, of Stony Point 

 P. O., East Baton Eouge, La., claims some details in a simple pump of 

 this type which seems to have no very special advantage for our present 

 I>urposes. 



Mr. TT. TT. Mallory, of Holland Patent, Oneida County, Xew York, 

 obtained in a pump similar to the above, and in patent Xo. 237193, 

 February 1, 1881, a pump-cover, consisting of a tube which bends hori- 

 zontally and then downwards as a handle, overflow spout, and guide to 

 the piston-rod, which works through a hole in its top. 



Patent Xo. 92194, July 6, 1869, secured to H. and A. Kaiser, of Co- 

 lumbus, Ohio, a pump of this kind but permanently attached inside of a 

 common watering-pot, its basal branch-spout with excurrent valve, co- 

 incides with that of the pot and bears a rose or substitutive solid-jet 

 nozzle as desired. 



A pump granted in patent Xo. 86287, January 26, 1869, to Mr. A. M. 

 Dix, of Shelton, England, has the cylinder-cap clamped to cross-bars 

 inserted in the upper part of a suitable receptacle. There is a stuffing- 

 box above for packing, and below this an outlet from the upper part of 

 the cylinder is extended downward by a drip-tube upon the side. A 

 diaphragm-strainer is inserted in the chamber of the discharge- valve. 



A pump having similar construction to those just noticed, but with 

 the valves reversed, giving suction through the basal branch-spout and
