GENEKAL ACCEiSSURIES B\)R WINTER SPRAYING.

being considered, is that the nozzle discharges the spray at an angle 

 of about 4:5^ with a line leading directly from the sprayer. I'his 

 gives the nozzle the advantages of both the lateral and direct dis- 

 charge. The work of either of these types (figs. 1, 2, and 3) may be 

 accomplished with this angular discharge. 



Makers of cyclone nozzles of all kinds are usually able to supply 

 the discharge plates of the nozzles separately, and this is convenient 

 for the grower, where the original discharge plates have been worn 

 out. The separate discharge plates usually sell at 25 cents each. 



HOSE AND EXTENSION PIPES.

Rubber hose of good ((uality is most satisfactory for ail kinds of 

 sprav work. The strongest and best hose will usually prove cheapest 

 if properly cared for. All hose should be 

 thorouffhlv washed, both inside 

 and outside, at the close of each 

 day's work, and it should be 

 well scrubbed, washed, and dried 

 when the spray work is com- 

 pleted, and stored in a uniformly 

 cool, dark, and medium dry place. 



Practice varies somewhat as to the internal diameter of 

 hose used. One-half inch is perhaps the most common size. 

 The external diameter of the hose should not be so small 

 nor its flexibility so great that it will easily kink and twist 

 upon itself. Hose which does this is a constant source of 

 annoyance, causing loss of time and often endangering itself. 

 Where possible, it is best to have all lines of discharge hose 

 leading from the pump pass from the back end of the wagon, 

 between two short stakes, one at each corner. With such 

 an arrangement there is little danger of its being caught in 

 the wheels or run over by them. Many lines of hose are 

 injured or destroyed in this way. The stakes at the back 

 corners of the wagon also serve as a means of winding up 

 the hose preparatory to going to or from the orchard. 



Couplings for connecting 1, 2, 3, or 4 lines of hose with 

 the pump may usually be obtained from responsible hard- 

 ware firms, or through them from the manufacturers of the 

 pumps used. The more common hose couplings are nearly 

 always in stock at such hardware houses. 



For most pumps it is well to supply wire-extended suc- 

 tion hose (fig. 4). Some styles have the spiral wire coil 

 within the interior; others have it embedded in the rubber. 

 When the metallic spiral is exposed to the spray in the interior of 

 the hose it should be of brass, if possible, to enable it to withstand 

 the corrosive action of the sprays.
