\Vc do not consider it safe to use the oil consecutively year 

 after year. When we have used the oil one year, we endeavor 

 to use the lime and sulphur the next. 



The lime and sulphur treatment we use more extensively 

 than either of the others. The formula we use is: 17 pounds 

 of lime, 17 pounds sulphur, to 50 gallons of spray. We cook 

 it in vats elevated high enough to drain into our spray tanks 

 and use large molasses faucets to draw off the prepared solu- 

 tion. xA.t one of our cooking stations we have a steam pump 

 connected with the boiler to elevate the water. At the other 

 two we use large threshing pumps. We usually prepare a 

 hundred gallons at a time, and at each station have two vats, 

 so that there is one ready all the time. A hundred gallons 

 is about all we can draw through our orchards at the time 

 of spraying. In preparing a hundred gallons we first pump 

 about thirty to forty gallons of water into our cooking vat, 

 and turn the steam into it, bringing it to a boiling point. 

 Then we put in our lime, which is good fresh lime, and it 

 soon commences to slake in the boiling water. When the 

 lime is pretty well slaked we put in our sulphur and stir and 

 cook for at least an hour. The results obtained with the lime 

 and sulphur depend entirely upon the thoroughness of the 

 application. There is no danger of getting on too much and 

 there is no reason why we can't control the scale on all our 

 orchards with it, except our apples, and I belie\e we can 

 hold it in check on them where they are not over large. In 

 applying it we always spray with the wind. We use two 

 leads of hose with each rig. In our smaller orchards we 

 spray one side of two rows at a time, the men who spray both 

 walking. While, in our apples, one man sprays from the tower 

 and the other with at least a ten-foot rod from the ground, 

 spraying one side of a row\ 



The crude oil emulsion we prepare 1>\- putting thirt\ or 

 forty gallons of water in spraying tank, then put in twelve 

 or fifteen pounds of whale oil or other soap, and boil until 

 soap is dissolved. Then jnunp fiftv gallons of oil into the 

 tank, keeping the steam turned on all the time and the agi-
