Soft soap . . . . . . 12 lb. 



Water 100 gallons. 



Preparation. — The soap is dissolved in boiling water, and when still 

 very hot, better still just boiling, the paraffin is added, and the whole 

 churned by means of a force pump into a creamy mass. About ten 

 gallons of water are sufficient to do this, and then the remaining water 

 is added gradually. 



The Solar Distillate Oil is undoubtedly the best to use, but excellent 

 results have been obtained with Tea Rose. 



Uses. — For the destruction of mussel scale eggs in the winter, oyster 

 shell bark louse, and brown currant scale.
