on the other hand too little, will cause incomplete slaking 

 of the lime. In this way the heat generated by the slaking 

 lime is taken advantage of, and by adding the sulfur first, 

 plenty of time is given for removing the lumps. 



By the time the lime is thoroughly slaked the fire should 

 continue the boiling, so that the time of boiling begins with 

 the addition of the lime. The salt and about one-fourth of 

 the water should now be added and the whole boiled from 

 one to two hours, keeping it frequently stirred in the mean- 

 time. At the end of this period screen into the spray tank, 

 add the necessary amount of liot water and apply to the 

 trees hot. 



The wash, when properly made, is a heavy reddish-brown 

 liquid, very caustic and having a strong sulfur odor. The 

 heavier materials settle upon standing, leaving a lighter 

 liquid both in color and weight. 



Application On account of the heavier ingredients of 

 the wash quickly settling to the bottom, means should be 

 provided for agitating the mixture in the spray tank. This 

 is best done, of course, by the power outfit. In the absence 

 of this a gearing may be attached to the wheel of the wag- 

 on and the mixture agitated while going from, one tree to 

 another. A still simpler way is to stir frequently by means 

 of a hoe or paddle. 



The nozzle should be of the stopcock type, which will 

 permit of ready cleaning. The type of spray should be a 

 rather coarse one which will thoroughly wet the insects.

Thoroughness in application cannot be too strongly 

 urged, and no part of the tree should escape treatment. 



Time of application. The Lime-Sulfur-Salt wash is for 

 winter use only. It must not be used when trees are grow- 

 ing for very grave injury will be the result if it is applied 

 at that time. When the trees are dormant it can be safely 

 used upon them. Such weather conditions in the winter as 

 will permit work in the orchard will be satisfactory for ap- 

 plying the Lime-Sulfur-Salt wash." 



The difficulty attendant upon the preparation of this 

 wash has led to a large amount of supplementation with
