Fourth annual report of the superintendent for suppressing the gipsy and 

 brown-tail moths, L. H. Worthley (Ann. Rpt. Supt. Suppressing Gipsy and 

 Brown-tail Moths [Mass.], 4 (1908), pp. 75, pis. 12).— During 1908 the fight 

 against the gipsy and brown-tail rn,oths was carried on along practically the 

 same lines as in the 3 preceding years (E. S. R., 22, p. 55). The climatic con- 

 ditions were favorable to the caterpillars but decidedly adverse to the increase 

 of certain fungus and bacterial diseases which have in recent years been of 

 great assistance as checks, so that the pests developed very rapidly. The prin- 

 cipal devastation was confined to woodlands of low valuation. 



The experience of the year showed the importance of equipping each city 

 and town with adequate spraymg outfits. Scouting during the early part of 

 the year by about 100 trained men resulted in the discovery of a number of 

 small colonies of the gipsy moth in several towns along the border of the 

 district previously known to be infested. 



The brown-tail moth was found to extend over an area comprising more than 

 \5,000 square miles. A list of 192 towns known to be infested by the gipsy 

 moth, and maps showing the area infested by the 2 pests on .January 1, 1909, 

 are given. 



Experiments conducted have shown that young gipsy moth caterpillars can 

 not live on white pine foliage in their early stages, and seem to give final and 

 conclusive proof that where the hardwood growth is thoroughly destroyed in
