the crowns, resulting in the formation of a collar of arsenic at the 

 ground line. Removal of the soil about the crowns after such heavy 

 spraying would probably eliminate all trouble. 



We must apply arsenical sprays for codling moth and other insects, 

 but proper discretion should be used in its application, and especially 

 should care be exercised to prevent the collection of quantities of the 

 liquid at the crown. It is often necessary to spray very heavily and 

 in such cases it -is almost impossible to keep the liquid from running 

 down the trunks, and the only remedy is its removal with the soil from 

 about the tree. 



THE FROST PROBLEM. 



By A. J. CooKj State Commissioner of Horticulture. 



Most of us pay extravagantly for fire and life insurance for the 

 security it gives and more for the comfort which attends this feeling 

 of security. 



The plum curculio is a serious insect pest. I heard Judge Ransdall, 

 a very successful plum grower of Michigan, say once that he thanked 

 the Lord for this insect. His philosophy was as follows: It is easy 

 to control this enemy, but most persons will not do so. This insures 

 my getting a fine crop of superior fruit, and I am always sure of a 

 great price and a ready market. He could quote Shakespeare with 

 joy : ' ' Sweet are the uses of adversity. ' ' 



Some of the citrus growers of the South may regard the frost calam- 

 ity of last January in the same happy frame of mind. One firm 

 expended some $28,000 in the first, and has already spent nearlv three 

 times as much to improve its equipment since the freeze, yet the 

 readiness of the firm for the fray saved its fruit and trees, and it is 

 ahead many thousands of dollars. 



Three localities in the southland were prepared for frost last year 

 to a greater or lesser degree: Pomona, Corona and the great Limoneira 

 lemon grove. In these localities the saving was immense. Does not 

 this all tend to prove that the citrus growers of the State face an 

 opportunity that may return a rich harvest of profit? 



We see "by the press that Pomona is pleased with her last year's 

 expenditure. She has paid out one half of a million dollars to increase 

 her equipment for frost protection. She will have 10,000 acres of 

 citrus groves with improved oil pots for heating. The example of 

 Colorado is being followed, as the chambers of commerce and business 

 associations are organizing to give aid in case the "Storm King" comes 

 and help is needed. The motorcycle brigade, organized last year, will 

 be continued and strengthened, and the superior telephone equipment 

 of the Pomona Valley wall be at the service of the citrus growers. 



News comes from Redlands that the growers there are also alive to 

 the necessity of quick and energetic action, and they are putting 

 thousands upon thousands of dollars in this effort to protect against 

 the possible freeze of the future. 



The North is fortunate in her early market, but that will not save 

 her trees. San Diego had never had a damaging freeze before last 

 winter, and no part of the South suffered more in January, 1913, than
