770 CONNECTICUT EXPERIMENT STATION REPORT, I907-I908. 



the trunks of trees, having been killed by a fungus, the prevalence 

 of which has undoubtedly been an important check to these 

 insects and will render them less common next season. 



Plant lice were abundant and checked the growth of young 

 apple trees in orchards and nurseries. 



Mites (probably Tetranychus bicolor Banks) were abundant 

 everywhere on chestnut, and the same or an allied species was 

 also on oak, causing the leaves to turn brown late in the summer. 

 The pear leaf mite, Eriophyes pyri Nal., was prevalent, and speci- 

 mens were received from several localities, where it formed red- 

 dish galls upon the leaves. 



Nursery Inspection. 



The annual inspection of nurseries, as provided for by the 

 General Statutes (Sections 4388-4389), was begun this year on 

 August 27th, or about a week earlier than usual. Fair weather 

 prevailed and enabled us to nearly complete the work by the 

 middle of October, though not wholly finished until November. 



The condition of the nurseries of the state was on the whole 

 found to be somewhat better than last year, but there is no 

 decided change. Individual nurseries presented differences, some 

 being better and some worse. In a region thoroughly infested 

 with San Jose scale, where nurserymen have carefully sprayed 

 their growing stock with soluble or miscible oil, one part in not 

 'more than fifteen parts of water, the plantations have been much 

 improved, some being comparatively free from scale. On the 

 other hand, where this treatment was done indifferently or care- 

 lessly, or neglected altogether, the stock was in bad condition and 

 much of it was destroyed. 



The inspections were made by Messrs. Britton, Walden, G. H. 

 HoUister and S. P. Hollister, the first three being employed 

 throughout the work and the last helping only about ten days in 

 the large nurseries. 



Two nurseries were inspected during the spring and forty in 

 the fall, making forty-two inspections. Forty-two certificates 

 were granted. The death of one nurseryman and the appearance 

 of five new firms changes slightly the list, which follows :
