trees were brown as if scorched by fire, and not. only fruit 

 trees, but also woodland trees, were injured in this way. 



The eg'gs hatch in six or seven weeks after being- de- 

 posited, and the }oung cicadas drop to the ground and bur- 

 row in it to a depth of between twelve and eighteen inches, 

 where they live for seventeen years by sucking- the sap from 

 the small roots of various trees. They have appeared in 

 Connecticut regularly every seventeen years since 1724. 



The peach sawfly, Pamphilius persicum MacG., has in- 

 creased sufficiently since \^>07 to warrant the spraying in 

 1911 of 20,000 trees in the Barnes orchard at Durham, and 

 nearly 10,000 in the Martin orchard at Wallingford. For 

 this purpose lead arsenate was used, three pounds per barrel 

 at Durham and two pounds per barrel at Wallingford. Mr. 

 Martin also used commercial lime-sulphur for a fungicide, 

 with the lead arsenate, at the rate of 1-166 and 1-100, and 

 regards it as a good investment. He had no injury from the 

 spray, and the sawfly caused no damage except on a few 

 isolated trees, which were not sprayed. Some injury resulted 

 from the lead arsenate in Barnes Brothers' Durham orchard. 



Excellent progress has been made in controlling the 

 gypsy moth. No caterpillars were found at Stonington last 

 summer, and the scouts were unable to find any egg masses 

 there this winter, and it is believed that the colony has been 

 eradicated, x^t WalHngford about 1,550 caterpillars were 

 destroyed in 1911. and the infested region has just been ex- 

 amined for egg masses, and only five were found — showing 

 that the careful work done there by Mr. Caffrey and his men 

 is eft'ectivelv holding the pest in check. 



The brown-tail moth is present in the northeast corner 

 of the state, and is distributed over at least five towns, 

 namely, Thompson, Putnam, Woodstock, Pomfret and Kil- 

 lingly. Over 7,000 nests were destroyed there last winter, 

 and men are now going over the territorv to destroy the nests
