74 JOURNAL OF ECONOMIC ENTOMOLOGY [Vol. 3 



a carload of Crataegus was shipped late in the fall of 1908 from an 

 eastern state. All the trees were heeled in over winter. In the spring 

 the trees were planted in groups of 12 to 15 trees in an area of about 

 11/2 acres. Later, about the time brown-tails pass to the pupae, 17 

 caterpillars were found. It was then too late to spray with arsenical 

 poisons, as feeding had ceased. We had no knowledge as to how many 

 insects were present, but our only course to pursue was to destroy 

 the pupa? wherever they might be and at the same time save the valu- 

 able thorns and the large shade trees nearby. 



Following thorough inspection, all trees were sprayed two or tkree 

 times with oil emulsions. The cultivated land and the heavy sod land 

 (after the grass was cut, oiled and burned) was burned over with 

 cyclone spray. Sixty or seventy barrels of crude oil were forced 

 through suitable nozzles and the oil ignited at the end of the nozzle. 

 The sod was burned black and the cultivated part was rolled and 

 reburned. Some portions had three burnings. Entire success seems to 

 have rewarded us. as acetylene gas trap lanterns kept going for ten 

 nights at the right time for moths to fly caught no brown -tails, and 

 subsequent inspection revealed no moths or nests to date. 



The state Legislature in April saw fit to amend our horticultural 

 inspection law when their attention was called to the possibility of 

 brown-tail and gypsy moths becoming established in the state. Suffi- 

 cient appropriations were provided, and the Commissioner of Agri- 

 culture was authorized to issue such orders as in his judgment were 

 necessary to control in any emergency. 



No box or package of nursery stock brought into the state can be 

 opened without first obtaining consent of the Commissioner. Custom 

 House brokers and importers are required to register their names and 

 addresses in the Department office. They and transportation com- 

 panies give such information as the Commissioner shall from time to 

 time require. 



Last spring custom house brokers were courteous and gave us lists 

 of nearly all of their importations for this and other states, but now 

 with a law to require information they hold, and justly so, that we 

 are entitled to information only relative to stock for New York State. 



The following is a summary of the work performed on imported 

 nursery stock :
