RED SPIDER. 197 



out, however, spraying 1 with water should be reg- 

 ularly practiced, as before described, and for this 

 purpose it will be found desirable to devise some 

 means of getting on the minimum amount of water 

 with the maximum amount of force. It will re- 

 quire a pressure of at least twenty to twenty-five 

 pounds to prove effective against spider. To get 

 the water on, however, without drenching the beds 

 is often a rather difficult matter, and for this rea. 

 son we have devised a simple spraying tip, which 

 is found to answer the purpose admirably. This 

 spraying tip may be attached to the end of a three- 

 quarter inch hose, or where the beds are wide we 

 prefer to use a short lance made of light brass pipe. 

 This lance is one-quarter inch in diameter and 

 usually about two feet long. The spraying tip is 

 fastened to one end, while the other end is provided 

 with a connection to screw on to the three-quarter 

 inch hose. The tip itself consists merely of a 

 piece of brass flattened out at the end and provided 

 with a narrow slit, through which the water is 

 forced. This slit is so adjusted that the water 

 issues through it in much the shape of a gas flame, 

 but, of course, very much larger. At a distance 

 of twenty to twenty-five inches from the end of 

 the slit the water breaks up into innumerable fine 

 drops, which are thoroughly effective in washing 

 the spiders from the leaves and not injuring the 

 latter in the least. With a little practice the beds 

 can be gone over quickly with this device, and
