204 Twexty-Seco^d Annual Report of the 



to advise relative to tlie treatment of old orchards, and to give 

 opinions relative to sites for new plantings ; thus, in many ways, 

 the care of orchard trees comes under the supervision of our 

 inspectors. 



Considerable attention was given to the peach yellows and little 

 peach diseases during the summer. 



Since our so-called orchard inspection is but incidental to our 

 other work, statistical records of what we have done do not show 

 the very considerable usefulness that the inspectors of this Bureau 

 are to the growers of fruit. Our inspectors live in strictly orchard 

 counties, and their suggestions are drawn upon by owners of or- 

 chard trees who desire help. 



The following is a statement of orchard work reported in 1915 : . 



Number of orchards carefully inspected, 1,139. 



Vineyards, 520 acres. 



Currant plantations, 120 acres. 



Berry plantations, 69 acres. 



Number of trees in orchards, 1,175,000. 



Number of trees diseased with yellows, 2,100. 



Number of trees diseased with little peach, 760. 



Number of trees infested by San Jose scale, blight, etc., 7,208. 



N umber of plants infested by scale, 1,125. 



POTATO QUARANTINE 



The work done in Franklin and Clinton counties during the 

 past year was a continuation of the labor necessary under the 

 Federal and State quarantine for these counties, for the control 

 of powdery scab. The Federal Government gradually withdrew 

 from the inspection and the potato quarantine was removed ; first, 

 by the Federal Government, and then by the State. 



Much interest in this work was developed among the growers 

 of potatoes in the northern part of the State, as there was a demand 

 for potatoes for seeding purposes that were known to be free from 

 disease. This subject is more fully set forth by the report of Mr. 

 H. C. Sands, who had charge of the enforcement of the quarantine. 

 Later during the year Mr. Sands had opportunity to visit several 

 portions of the State to accumulate information relative to the dis- 

 eases of this important crop. It is believed that the accompanying
