620 ANNUAL REPORTS OF DEPARTIVIENT OF AGRICULTURE. 



The inspection and quarantine -work in both the eastern and 

 western areas has been on a cooperative basis with the States con- 

 cerned. 



RESTRICTIONS ON ENTRY OF BROOMCORN. 



For several years the entry of foreign broomcorn has been safe- 

 guarded by requiring the steam disinfection of all such corn at ports 

 of entry, this treatment being necessitated by the fact that in spite 

 of such efforts as have been made on the part of foreign shippers 

 to select and export sound material, all broomcorn coming to the 

 United States has been more or less infested with the larvae of the 

 European or other corn borers. Practically all such imports have 

 been from Europe, but broomcorn from other parts of the world 

 has indicated a similar danger of carrying stalk borers new to the 

 United States. 



Early in February, 1923, in view of the unusually large imports 

 of broomcorn in prospect, it seemed desirable to limit entry to the 

 period between November 1 and March 31 of each year so that any 

 risk from delay in fumigation would be further safeguarded by the 

 fact that the insect would still be in a dormant winter condition. 



Due to the shortage of production in the United States, the entry 

 of broomcorn exceeded all previous records and the supply awaiting 

 fumigation and in transit as March 31 approached was such as to 

 make it apparent that it could not be disinfected and disposed of by 

 that period. It became necessary, therefore, to order the removal or 

 transfer of some of this corn from the port of New York by lighter- 

 age to Boston, where further delay in its disinfection would involve 

 no new risk to the United States. 



In view of the generally unsatisfactory situation which developed 

 in March and April at the port of New York on account of the 

 great quantities of broomcorn entered and the delays in its disin- 

 fection, the provision for the entry of this product was again 

 changed, limiting entry at New York, San Francisco, and any other 

 port where sterilization is possible, to the period between November 

 1 and February 28 of each year, but permitting entry throughout 

 the year at Boston. Any broomcorn arriving at New York or other 

 port except Boston subsequent to February 28 and prior to November 

 1 will be required to be immediately transferred to Boston by lighter- 

 age or other means and without being unloaded on the New York 



docks. 



JAPANESE BEETLE QUARANTINE. 



The quarantine on account of the Japanese beetle was entirely 

 revised, effective April 15. This revision was based on a conference 

 held by the Federal Horticultural Board and Bureau of Entomology 

 October 12, 1922, participated in by the official representatives of 

 New Jersey and Pennsylvania. A new policy in control methods 

 was agreed upon at this conference, involving what is termed the 

 "zoning system." Under this system the city of Philadelphia and 

 its suburbs are now included within the controlled area so as to 

 allow free movement of locally produced farm products within the 

 more important distribution radius from Philadelphia. In point of 

 fact, the Japanese beetle has already extended its range to include
