trees are now in full vigor and, from a distance give few 

 signs of the severe heading back of several years ago. Last 

 fall they were heavily laden with excellent fruit and were 

 practically free from scale, except individuals here and 

 there which could not be thoroughly sprayed owing to one 

 cause or another. It must be admitted that these desirable 

 results were obtained only after years of patient trial, and 

 even then might have failed had the execution of the task 

 been in the hands of a less determined or less conservative- 

 man. 



This large fruit grower has taken a practical experi- 

 mental course with mechanical mixtures of crude oil, the 

 home-made lime-sulfur wash, the Cordley lime-sulfur wash 

 and the commercial lime-sulfur wash. It has been found 

 that the applications of oil while beneficial, were not so 

 uniformly successful as the lime-sulfur preparations. Ex- 

 perience soon showed that the keynote of success lay in the 

 thoroughness of application and that the latter could be 

 secured only under certain favorable conditions. It has 

 been Mr. Hart's invariable practice for some years, to 

 spray the trees with winds from opjDOsite directions, and 

 whenever this has been possible the results have been most 

 satisfactory. Occasionally adverse winds have hindered 

 the work, and invariably the partly sprayed trees became 

 badly infested and, in some instances, rather seriously in- 

 jured before the close of the season. These results were ob- 

 taind not only upon the somewhat resistant Baldwins, but 

 also with the Ben Da,vis, a variety very subject to scale in- 

 jury. Mr. Hart is convinced that under his conditions at 

 least, it is almost imperative to have some material whichr 

 can be applied the moment weather conditions are favor- 

 able, and thus avoid the initial delay incident to a some- 

 what prolonged boiling of the home-made material. Last 

 spring he tested the Cordley formula making it up in ad- 

 vance, and also used one of the commercial lime-sulfur 

 washes. Both were so successful that they will be tried 

 out on a larger scale another season. 



There is no longer any question as to the practicability 

 of controlling San Jose scale provided the work is thorough- 

 ly done and satisfactory materials employed. There is some 

 difference of opinion as to the relative value of the various 

 preparations now used for this purpose. Those not meet- 

 ing the demands of fruit growers have been ruthlessly dis-
