Aside from the certificates required for shipping forest products 

 outside the infested territory, a large number of permits, aggregating 

 2,624 to January 1, 1910, have been issued allowing the transporta- 

 tion of these products inside the infested district." 



This inspection feature of the work is of great importance and 

 must be well organized and thoroughly enforced if the gipsy moth is 

 to be prevented from becoming established at distant points. This 

 is especially true, since at the present time large forest areas are 

 heavily infested, and in order to harvest the marketable lumber 

 many owners are cutting and shipping. Where large cutting opera- 

 tions are carried on it is customary to use portable sawmills, and 

 the rough lumber is often piled in the woodland where it may remain 

 one or two seasons. This may result in the lumber becoming badly 

 infested with egg clusters. (See PL VIII.) A number of cases have 

 been found which indicate that the moth has been spread by the 

 removal of these portable sawmills from one infested area to another 

 where no infestation existed. 



The report has recently been received that gipsy moth egg clusters 

 were found in Providence, R. I., on boxes which had been used 

 by market gardeners in shipping their produce. This feature con- 

 cerning the spread of the moth is very difficult to regulate, and about 

 the only measure seems to be the requiring of shippers of such prod- 

 uce to keep their grounds and premises free from the pest. The 

 thorough inspection and cleaning up of such premises will undoubt- 

 edly result in checking the spread of the insect in this way. 



DANGER OF INTRODUCING THE GIPSY MOTH AND BROWN-TAIL 

 MOTH FROM FOREIGN COUNTRIES. 



The suppression and inspection work which is being carried on 

 in New England of course can not prevent the introduction of these 



a From January 1, 1910, to May 25, 1910, 227 certificates and 102 permits were 

 issued. Several infested shipments were found, which were carefully treated before 

 being released. In addition to the New England States these shipments were sent 

 to New York, Pennsylvania, Delaware, Virginia, and Ohio.
