It also differs from the preceding resin washes in the manner 

 of preparation, and in being ready for application when mixed ac- 

 cording to the above formula, instead of forming a soap to be dis- 

 solved again in water. It is prepared as follows: 



Place all the ingredients in a large boiler with enough cold 

 water to cover them. Boil until dissolved, occasionally 'stirring, 

 and continue boiling for about an hour after the materials are dis- 

 solved, employing sufficient heat to keep the mixture in a constant 

 state of ebullition, and adding hot water when it is in danger of boil- 

 ing over. When sufficiently boiled it will assimilate perfectly 

 with water, which should then be added hot up to 50 gallons, slowly at 

 first and stirring occasionally, and then cold water until a sufficient 

 amount is added to make 100 gallons of the mixture. Before the 

 water is added the preparation is of a pale yellow color, but after 

 a adding it becomes dark brown. It must be strained through a 

 fine wire seive, or a piece of Swiss muslin, before applying to the 

 trees. 



Virtually the same remedy as the above, only in a little 

 greater strength and with the addition of a little kerosene, is re- 

 commended by the Calif oraia State Board of Horticulture for the red 

 scale on orange, and other scales on evergreen trees ; while the same 

 thing, only a little stronger and without the kerosene, is recom- 

 mended for Icc-r'ijfi on the orange. 



The following is the Riley-Hubbard formula for the kerosene 

 emulsion, which at proper strength will be found a very efficient 

 remedy for scales:

Prepare by boiling the water and soap together until dissolved, 

 and then pouring it, while boiling hot, into the kerosene. The
