have come from the nursery. Beyond three miles I could find noth- 

 ing, except in a newly started peach orchard six miles east of here, 

 where 1 found one small peach tree covered and this one without 

 doubt came from the nursery.'' 



The fact that these trees were of large size proves that they were 

 infested by the Scale that was carried to them, because they would 

 yet be comparatively small trees even if they were the very first in 

 fested with Scale that were brought into this State, as it has not 

 been with us more than about twelve years and is consequently 

 found only upon small trees, unless it be where it was carried from 

 younger trees to the older ones. As they stood at least ten rods 

 from the badly infested trees it shows conclusively that the Scale 

 was carried this distance, or nearly a third of a mile. This gives 

 full justification for establishing the half mile as a limit within 

 which the Scale must be held in complete check around nurseries 

 to avoid infestation of nursery stock, as is required by the State of 

 New York. 



"The name of the agent w r ho sold these trees and who has the 

 large part of the trade in this section is . Fol- 

 lowing this I went west and north and found that the Scale was 

 there also. I went north about three-fourths of a mile and found 

 it on trees fifty years of age with no signs of badly infested young 

 trees." 



No better proof is needed in finding the Scale on trees fifty years 

 of age, and no infested young trees nearer than three-fourth of a 

 mile, that the Scale was carried or spread over this entire distance. 



This valuable portion of the report shows that the Scale has 

 spread from the original center over a distance of at least three 

 miles, and it also emphasizes the importance of the work of inspec- 

 tion and demonstration which we are doing, and shows the ability 

 of the class of men whom we have engaged as demonstrators, not- 

 withstanding the fact that a self-appointed critic thought it wise to 

 refer to them as "experts of a month's training." While we do not 

 advocate destroying infested trees as in special cases, the destruction 

 of the isolated infested trees is important in such cases as the last 

 mentioned, in order to prevent the spread of the Scale from these 

 small centers of distribution. 



"Then I went one mile west of the town and found the Scale in the 

 peach orchard of J. P. G. This orchard is from three to four years 

 of age and after a thorough inspection T could detect not one badly 

 infested tree, but at short intervals I found branches with the Scale 

 thinly scattered over them showing beyond doubt that some foreign 

 body had carried it there. 



"These same conditions I found to prevail in two other orchards 

 near here. 



"In addition to this I made a trip to and found that these 



people were not behind the times and had already made the Scale a 

 common study in their town. Here I received an application for a 

 demonstration to be held next spring in the orchard of R. B. This 

 orchard contains about 3.000 trees and is a splendid place for a 

 demonstration. I send the application herewith. The people of 



are enthusiastic over the work and are spraying and 



ordering pumps." 



There is here such plain evidence that the Scale is carried by such
