De Ong (E. R.)- Soaps and Miscible Oils.— MtJdy. Bull. Cat State 

 Commiss. Hortic, Sacratnento, v, no. 5, May 1916, pp. 172-176. 



Fish-oil soap is prepared according to the following formula :• — 

 3 gals, fish-oil, 4 lb. caustic potash, 8 U.S gals, water. Against Aphids 

 the soap should be used at the rate of 1 lb. to 8 gals, water. Cresol soap 

 used in the preparation of miscible oils consists of 1 gal. fish-oil soap. 

 1*5 gals, cresylic acid and 0"5 lb. caustic soda. The soda and oil 

 are heated together until the former is dissolved, then the cresyhc 

 acid is added and the mixture raised to a temperature of from 290° to 

 300° F. This soap will keep for any length of time. If required for 

 the manufacture of an oil emulsion, 3 gals, kerosene should be added to 

 the warm liquid and then 2 gals, water. When used in combination 

 with distillate or crude oil, the soap should be mixed when cold with 

 from 5 to 10 times its volume of oil. The necessary dilution may be 

 calculated from the volume of oil used ; if the soap dissolves six times 

 its volume of oil, the resulting mixture contains 93 '4 per cent, of oil, 

 and to obtain a 7 per cent, emulsion, 7*5 gals, of the stock emulsion 

 are added to 92*5 gals, water. 



G. P. W. Alfalfa Weevil Quarantine Conlevente. —Mthly. Bull. Cal. 

 State Coynmus. Hortic, Sacramento, v. no. 5, May 1916, 

 pp. 186-187. 



A conference was held at Salt Lake City during April to discuss the 

 alfalfa weevil [Hypera variabilis] and to consider quarantine regulations 

 which should aim at preventing the passage of goods liable to convey 

 this weevil from infested to non-infested States. In the opinion 

 of those present, a restrictive quarantine should be placed on potatoes 

 coming from Utah. With the exception of the representatives of 

 that State, there was a general agreement in favour of an absolute 

 quarantine on hay and cereal straw. A quarantine on lucerne seed 

 and bees was not regarded as essential. 



E. J. V. Alfalfa Weevil Inspection. — Mthly. Bull. Cal. Slate Commiss. 

 Hortic, SacrameiUo, v, no. 5, May 1916, p. 188. 



The annual inspection of the lucerne-growing districts in San 

 Bernardino county along the Salt Lake route failed to show the 

 presence of the weevil [Hypera variabilis]. This route crosses infested 

 areas in Utah and may become a factor in the distribution of the 

 insect.
