68 FUMIGATION INVESTIGATIONS IN CALIFORNIA. 



with such unanimous favor by a community of Cahforiiia citrus 

 growers demonstrates its value and economic importance. 



Since the first outfits were placed in operation at Whittle r, others 

 have adopted the improved system of dosage, and at the time of 

 writing this fully a dozen similar outfits in various parts of Los An- 

 geles and Orange counties, Cal., are using the new method in prefer- 

 ence to the old. That such a large number of practical citrus growers 

 in widely separated localities, who have been employing a system of 

 fumigation for many years, should accept an innovation within two 

 months, strongly indicates its superiority. 



FUMIGATION SIMPLIFIED. 



In the past many persons have been prone to look upon fumigation 

 as a process that is complex and more or less mysterious. In some 

 cases fumigators of years' experience have encouraged tliis widely 

 prevailing opinion, so that they might themselves be looked upon as 

 experts in a practice difficult to understand and only capable of 

 being successfully performed by men of long experience and special 

 quahfications. This is, of course, erroneous. The improved system 

 outlined in these pages shows how simple the practice of fumigation 

 may be made. Careful men who have never before heard of fumi- 

 gation can begin the practice of tliis system and are competent, after 

 instruction for a short time, to secure as good results as might be 

 expected from the most expert fumigator in California. This system 

 reduces fumigation to a matter of simple mechanical operation, 

 entirely intelligible to the average man, and one wherein the operator, 

 to obtain the best results, is required merely to proceed according to 

 the formulas and directions given. 



This system makes it possible for the crchardists to possess outfits 

 of their own — either individually or through joint ownership on the 

 part of neighboring fruit growers — and to do the work with their 

 own employees.
