over three cents per gallon. Even at this price many fruit 

 growers believe that they can spray their trees more econom- 

 ically with Scalecide than with lime and sulphur. The cause 

 for this belief may be partly attributed to the destructive char- 

 acter of the lime and sulphur on the spraying equipment, but 

 more particularly to the fact that, with its adaptability to the 

 use of a finer nozzle, the oil spray will go almost twice as 

 far as lime and sulphur. Admitting that there is good ground 

 for contention in regard to a preparation costing over three 

 cents per gallon, all doubt should be removed when we con- 

 sider a home-made preparation, costing about one cent per 

 gallon. Even when considered gallon for gallon, the home- 

 made soluble oil is cheaper than the lime-sulphur wash, which 

 including labor and fuel, cannot be made for less than one 

 and one-half cents per gallon. Oil emulsion may be made at 

 home at a cost not exceeding one and one- fourth cents per 

 gallon, and by securing the material in barrel lots, for less 

 than one cent per gallon. 



Coni'cnience. It is often difficult to secure a quality of 

 lime suited to the purpose of making the lime-sulphur wash, 

 and much of the failure to secure satisfactory results may be 

 attributed to a poor quality of lime. The preparation of the 

 wash requires care, time, fuel, unusual patience, and an elab- 

 orate outfit. It must be applied soon after being made, and 

 before it has become cold. On account of its corrosive efifect 

 on the hands and face of the operator, it is hard to secure men 

 to do the work. This is a serious objection when it is so 

 difficult to secure and retain good men for farm work. It 

 is true that there is some inconvenience in the preparation 

 of a home-made soluble oil. As mentioned in another place, 

 difficulty has been experienced in securing materials of the 

 proper grade. When the dealers come to know the require- 

 ments and to realize the demand for such materials this dif- 

 ficulty may be removed. With the proper materials, how- 

 ever, its preparation is extremely simple, requiring much less 

 care than an efficient lime and sulphur wash. It is less of- 

 fensive to handle, mav be made up during the slack season.
