Since this place, in which the wilt had operated, contained only 

 336 eggs with apparently living embryos on the average per cluster, the 

 size of these clusters was about one-fourth less than normal. The num- 

 ber of the fresh clusters, which were found to be 4, must thus be re- 

 duced to 3. The number of apparently living eggs of this locality 

 therefore was decreased, after Flacherie had worked, to about 7.5 per 

 cent.

 With the help of the assistant of the division agent two places were 

 selected for the experiments. The place which we will first consider 

 is situated near Hart Street, north of Greenwood Avenue, Beverly 

 Farms. It is an isolated wood of about 1 acre, mainly overgrown with 

 maple about fifty to sixty years of age, and yellow birch, and has dense 

 underbrush. The gypsy moth caterpillars were very numerous here 

 during the summer of 1909, but no disease was noticed among them. 

 A small percentage of egg clusters was killed with creosote during the
