Rio, and El Paso, Tex., as well as on the boundary line at Nogales, 

 Ariz. During the period under review many interceptions were 

 made of contraband material, some of which was infested with 

 exotic insects injurious to cultivated fruits and crops. The value 

 of this phase of the border work is evidenced by the fact that 33,636 

 pieces of contraband plants and plant products were taken from 

 passengers and pedestrians entering the States. 



EUROPEAN CORN BORER. 



The domestic quarantine on account of the European corn borer 

 was amended four times during the year to include such extensions 

 of territory as were determined from time to time. (See record on 

 p._31.) These extensions have all been in connection with old dis- 

 tricts and represent the natural and, in large part, unpreventable 

 local spread of the pest. There have been no reports of new centers 

 of infestation remote from the old known centers. 



The corn borer quarantine and regulations have been modified as 

 to the New England district, so that more funds could be devoted and 

 more work could be done in western New York, northern Ohio, and 

 some areas in Michigan immediately adjacent to Detroit, where the 

 invasion of this pest comes closest to the great Corn Belt of the 

 Middle West. 



The inspection and certification which was formerly carried out at 

 the point of origin of the products and applied to all marketed prod- 

 ucts, is now limited to products which are to be shipped out of the 

 quarantined area, and this is done very largely in the Boston whole- 

 sale market. This change makes a saving of approximately two- 

 thirds in the cost of inspection in this district — a reduction from 

 approximately $75,000 to $25,000. It has been necessary, however, 

 to maintain some inspection and certification at outlying points for 

 the inspection of ornamentals and vegetables which are shipped inter- 

 state directly from the point of production — farm or nursery. 



The inspection for the eastern New York district is conducted in 

 the wholesale markets in Albany, N. Y., and is limited to the inspec- 

 tion and certification of sweet corn grown outside of the quarantined 

 area but which comes into Albany for shipment interstate or other- 

 wise to points beyond the quarantine line. The inspection in the 

 western New York area is limited largely to the required certifica- 

 tion of products as a condition of movement into Canada, inasmuch 

 as there is little other movement out of the district. For the Ohio 

 and Michigan areas inspection has been maintained in the Cleve- 

 land markets to safeguard the movement of corn beyond the quaran- 

 tined area chiefly into the southern markets of Ohio. Inspectors 

 are also stationed in Michigan at Detroit and other ports of entry 

 from Canada within the quarantined area to prevent the entry of 

 quarantined products from Canada which have not been certified 

 by Canadian officials. The main highways leading out of these west- 

 ern quarantined areas have been under supervision and inspection 

 to prevent sweet corn on the cob from being carried out of the quar- 

 antined area in motors or other vehicles. In addition to this work, 

 field inspections have been conducted around all the infested areas to 

 determine the spread of the insect for the purpose of rectifjdng the 

 quarantine lines.
