injury to the trees, and was in some cases quite effective in 

 holding the pest in check. It remains to be determined whether 

 or not the continued use of these oils upon the same trees may 

 not result injuriously, even though a single application causes 

 no apparent injury. 



We are certain that the annual inspection of all nurseries in 

 the State will be a substantial check upon the further distribu- 

 tion of the pest upon nursery stock, though we cannot expect 

 that the danger from this source will be entirely eliminated by 

 anv system of inspection, however thorough, or any form of 

 legislation however stringent. Most nurserymen are now pro- 

 vided with facilities for fumigating their nursery stock, and we 

 strongly advise the members of this Society to demand that the 

 trees which they may purchase from any nursery be properly 

 fumigated before being shipped to them. 



Fall Web-Worm. The season has been remarkable for the 

 great abundance of the Fall Web-Worm (Hyphantria ciinea, 

 Drury.) during the summer and fall. Nearly all kinds of fruit 

 and forest trees were attacked and stripped of foliage, and the 

 injury extended all over this State and into other states. There 

 are two broods each year, the first usually doing little damage, 

 but the second brood of caterpillars begin their destructive work 

 in August, and frequently cause much damage. They form 

 little nests at the ends of the branches by drawing their silken 

 webs around a few leaves, and inside, the young caterpillars 

 feed, eating only the green portion of the leaf at first, but as 

 they become partially grown they are able to devour the whole 

 leaf except the mid-vein. The past season many large trees 

 were entirely defoliated, and the nests are now to be seen on 

 the trees of forest and roadside as we drive through the country 

 or ride over the railroads. In the orchard, of course, injury 

 will be prevented if the foliage is kept poisoned until late in the 

 season. It is very easy, however, to remove the nests when 

 first formed, as they are always at the ends of the branches, 

 and may be cut off with a tree pruner and destroyed. 



Hornets Injuring Fruit. During September, specimens of a 

 large reddish-colored hornet were received at the Station, with 

 the story that this species was responsible for considerable dam- 

 age to ripening fruit by rupturing the skin and eating the juice 

 and flesh. In the vicinity of New Haven, pears, especially, 

 were injured, and the insect had not been observed in previous
