Professor Hilgard, of the State University of California, 

 obtained satisfactory results from a tea, or decoction made by 

 pouring boiling water upon the Iniliach flowers (not ground), 

 and covering as in making tea, it being found that Ijoiling is 

 injurious to the strength of the liquid. For plant-lice, etc., 

 use one pound of the tea to twenty-four gallons of water. For 

 beetles, one pound to every ten gallons. Apply with spray 

 nozzle. The powdered buhach can be used in this manner. 

 Strain if necessary. See No. 83.

Dig a trench or ditch about twelve inches wide and twelve 

 to fifteen inches deep between the invading army of worms 

 and the fields to be protected, the side of the ditch next to the 

 fields to be perpendicular, or dug under, if possible, to prevent 

 the worms from creeping up. Every fifteen or twent}' feet a 

 deep hole should be dug in the bottom of the ditch, Avhere the 

 worms can collect. In these holes they can easil}^ be destroyed 

 by pouring coal oil on them, or dusting them with buhach, or 

 placing straw in the ditch and setting fire to it. A little coal 

 oil sprinkled on the straw will make it burn more readily. 

 This plan proved effectual in this vicinity (Sacramento) in 

 1879. Effectual results were derived from plowing a fur- 

 row eight inches deep, and kept soft by dragging brush in it. 

 But two or three furroAVS, some two or three feet apart, would 

 be better, and the vegetation on the space between them dusted 

 with Paris green or London purple, one pound of either (the 

 former is preferable) mixed in twenty pounds of coarse flour 

 and dusted on the vegetation, or one tablespoonful of either
