to actual flight; had it not been for the protection this afforded 

 eastern Louisiana there is little doubt that the most of Louisiana's 

 cotton-producing territory would now be infested, instead of the pest 

 being confined entirely to the western parishes." (Circular 9, La. 

 Crop Pest Commission.) 



This statement may possibly be somewhat overdrawn, but the 

 writer believes it is substantially correct. At any rate, with one 

 exception (due to intentional introduction) no isolated colonies far 

 beyond the territory reached by flight have ever been discovered. 

 How much of this is due to the legal restrictions that have been de- 

 scribed, and how much to accident, cannot be determined with cer- 

 tainty. It seems evident, however, that the possibilities for the spread 

 of the weevil in certain classes of farm products are great. It is, 

 therefore, altogether likely that many introductions have been pre- 

 vented, and the writer believes the value of the quarantines has far 

 overbalanced the temporary interferences with shipping that they 

 have caused. 



NOTES ON ENTOMOLOGICAL INSPECTION IN THE DISTRICT 



OF COLUMBIA 



By E. R. Sasscer 



Although there are no laws on the statute books of the District of 

 Columbia governing the inspection of incoming and outgoing plants, 

 every attempt has been made to examine such material. Until the 

 enactment of the Plant Quarantine Act on August 20, 1912, this work 

 was carried on by the Bureaus of Entomology and Plant Industry of 

 the Department of Agriculture, and, subsequent to that date, has been 

 conducted under the supervision of the Federal Horticultural Board. 

 All plants entering or leaving the District of Columbia are inspected 

 both from an entomological and a pathological standpoint. 



There are two classes of inspection in the District of Columbia, 

 namely, commercial and departmental. The former consists in the 

 inspection of all imports for florists, department stores, and private 

 individuals, and includes such plants as boxwood, azaleas, rhododen- 

 drons, roses, hydrangeas, orchids, etc. Since the first of the current 

 calendar year some 496 cases of plants have been examined. 



"Departmental inspection" includes the careful examination of all 

 plants and plant products introduced and distributed by the Office of 

 Foreign Seed and Plant Introduction as well as other offices of the 

 Bureau of Plant Industry. Some 2,000 packages containing various 

 plants and plant products have been examined during 1913. For the 

 accomplishment of this work there has been provided a special quar-
