to our own needs. With the hope of developing discussions that may 

 prove profitable in this exchange of ideas or plans and experiences, 

 we take this subject, and open it for general discussion by stating, 

 first, some of the features of our own work, outside the actual inspec- 

 tion service, to prevent dissemination of pests. 



Of course, with the nursery inspection we make a special feature 

 of the San Jose scale and require all infested stock to be destroyed 

 or removed to another part of the nursery and treated thoroughly 

 with an approved insecticide, like strong lime-sulfur solution, and 

 absolutely cleaned up, before it can be sold or shipped. Also, we 

 follow the regulation method of requiring all nursery stock of kinds 

 liable to infestation by San Jose scale, grown in an infested nursery, 

 to be fumigated in the prescribed manner, and a certificate of fumi- 

 gation attached, before it can be sold or transported. We inspect all 

 nurseries during the summer, beginning August 1, and also during the 

 winter, when the deciduous trees are dormant, and pests are to be 

 more easily detected. 



All of the above is a regular part of the inspection work. In addi- 

 tion to this more has been found necessary. For example, we have 

 found it necessary to inspect not only the nursery stock, but all the 

 older fruit trees and other trees and shrubs liable to infestation by 

 scale growing in or near the nursery. We have found our nurserymen 

 quite anxious to grow clean stock, and to be spared the expense and. 

 trouble of destroying infested stock and fumigating that which they 

 sell and ship. 



The inspection of surrounding orchards and certain otl^er trees and 

 shrubs has aided greatly in eliminating the original source of the 

 scale, because this inspection, even though noi on the nursery property, 

 is followed by compulsory treatment. The infested premises near 

 nurseries are re-inspected, and the inspector makes certain that the 

 scale is cleaned up, before the next season for its spread. Where the 

 owner does not do this according to our directions, we proceed under 

 legal authority to do the work, and the charge becomes a lien upon 

 the property, the same as tax. 



In addition to seeing that the premises surrounding the nurseries 

 are kept clean of injurious insects and diseases that would attack the 

 nursery stock or be disseminated thereon, we impress upon the nur- 

 seryman the importance of selecting his cions from clean stock. 



We know of one instance of a large nursery free from scale, ex- 

 cepting on two varieties of apples. Upon inquir\' we found that 

 these were propagated by fruit grafts made from cuttings furnished' 

 by a fruit grower of New Jersey, who was anxious to have his own 

 bearing trees used for propagating stock for himself. It is the earnest
