STRAINER BOX. 



The strainer box is one of the most important parts of the spray- 

 plant. The one used is modeled after that advised in Bulletin No. 115 

 of the Pennsylvania State College Experiment Station. Two-inch clear 

 redwood has been used for this box and all joints are mortised and set 

 in white lead. This makes a very substantial box; lighter material 

 might be used, but it is probable that, with the rough usage it gets in 

 being pulled out, with 200 pounds of solution in it, in order to clean it, 

 the seams would soon open and the whole box rack out of shape. At 

 the end of each day 's run the box should be drawn out on the platform, 

 the solution emptied into the tanks and whatever sediment has collected 

 should be taken out. 



In this strainer the liquid going in at (0) — end view Fig. Ill — 

 strains up through the strainer screen (F) and runs out through the 

 elbow (L) to the trough, which conducts it to the storage tanks. The 

 sediment is thus thrown to the bottom of the strainer box and the screen 

 is kept clean. A partition (D) is put through the box, extendingdown 

 to six or eight inches from the bottom. The screen — ordinary window 

 screen — is nailed on a frame (F) which rests on strips (c) nailed 

 around the inside of the box and partition, and is held down by four 

 pieces (A). The four pieces (A) are put on with one screw in each so 

 that they may be turned and the strainer easily removed. 



TOTAL BILL OF MATERIALS AND LABOR. 



A plant for the home manufacture of lime-sulphur solution, con- 

 structed along the above described lines and having a capacity of 

 twenty-five barrels a day, can be built for $186.58; in many cases the 

 cost can be greatly reduced by the use of second-hand materials. Our 

 own plant required an expenditure of less than $25, as we had prac- 

 tically everything already on the ranch ; but we have figured the invest- 

 ment as amounting to about $140. Of course retail prices vary in 

 different localities, but a close estimate can be made from the following 

 list of costs taken from the above itemized bills : 



Lumber $11 83 



Steam and water fittings 7 75 



One 5-horsepower boiler 100 00 



Three cooking barrels 4 50 



Two 700-gal. galvanized iron tanks 40 00 



Five extra barrels for field use 7 50 



Labor 15 00 



Total $186 58
