GARDEN TILLAGE.

or three fine strong sprays at one time. The liquid in ihe barrel 

 is kept agitated by a small stream of water passing through a 

 one-fourth inch pipe, having a one-sixteenth inch wide opening 

 near the feed p^pe of the pump, in the bottom of the barrel. 

 On one end of the barrel is shown a cone shaped strainer which 

 is much the best form to use. There are many styles of spray 

 nozzles on the market. For general use the McGowen, Vermorel 

 or Bordeaux are best. 



The lower end of the feed pipe is covered with a fine 

 brass screen. In the center of the side of the barrel is an open- 

 ing eight inches in diameter with a tight fitting cover. This is so 

 large that the barrel may be easily cleaned. The whole expense 

 of making this machine was as follows: One linseed oil bar- 

 rel, $1; pump, $6.50; 50 feet of one-half inch hose, $3; strainer, 

 $1.50; two nozzles, $1.25; bolts, etc., 50 cents. Total cost, not 

 including labor, $13.75. 



In buying machinery it is well to regard with suspicion 

 those that are very complicated, as the simplest is generally the 

 most durable in the end.
