found. This could hardly be explained in any other way than 

 that the birds were quite active agents in the spreading of these 

 pests. From evidence obtained it seems as if this was the case. 

 Another cause may have been that of the remains of the two 

 found on the bottom of the old sleigh at the Welch place. 

 These eggs were evidently scattered all over town and it would 

 have been an easy matter for these to have hatched, although they 

 might have been subjected to the freezing and thawing process 

 above mentioned. Birds could readily scatter them by carrying 

 the young larvae on their feet and legs ; this fact was established 

 without a doubt during the "Old Commission in Massachusetts." 



Plate XIII. This cut shows the manner of burlapping 

 explained on page 303. 



A bale of burlap will handle, on the average, about nine hun- 

 dred trees. Judging from the present outlook at least 30,000 

 trees will have to be treated during the season of 1908. At least 

 90% of the infestations burlapped during the past season are 

 free from the pest ; in other words the work done was so thor- 

 oughly done that not an egg-cluster showed up this fall, with 

 but few exceptions, and even then there was a sufficient reason 

 for it. 



Only one egg-cluster was taken in Eliot this fall from the 

 infestation of last summer and that one was back in an orchard 

 away from the trees burlapped. 



In Wells, Kennebunk and Kennebunkport nothing showed up 

 near the burlaps. 



YORK. 



On November 30th a scout was made of the property owned 

 by the following parties: — Malcom Paine, G. F. Austin and 

 George Ra}Ties on Raynes' Neck, and the summer place of 

 Prof. Ames of Harvard situated by the Godfrey Cave road 

 directly back and adjoining the estates of the above named par- 

 ties. These places were found to be badly infested. They 

 are situated directly across the river from the Thaxter infesta- 

 tion in Kittery, and the caterpillars were probably carried across 

 by the tide on drift wood as the wind and currents here favor 

 that theory. 



Plate XIV shows a part of the woodlot of Malcom Paine 

 where one hundred and fifty- four egg-clusters were taken ; the 

 most of them were found on the dead limbs, twigs and leaves
