 ovate, acuminate, pubescent above, somewhat shining 

 and villous below, one side smaller than the other, 3 in.

INSPECTION OF HORTICULTURAL MER- 

 CHANDISE. To guard against the introduction of 

 insect pests and plant diseases, governments have insti- 

 tuted inspection service at ports of entry and for inter- 

 state commerce. The regulations may be federal, or 

 state or provincial. 



The plant-quarantine act. 



A federal plant-quarantine act was enacted by Con- 

 gress August 20, 1912. This act authorizes the Secre- 

 tary of Agriculture to regulate the importation of 

 nursery stock and other plants and plant-products, and 

 to establish and maintain quarantine districts for plant- 

 diseases and insect pests within the United States, and 

 also to exclude by quarantine diseased plants or plant- 

 products from foreign countries or to provide such 

 regulations governing the entry of such materials as will 

 insure safety. 



The first general attempt to secure national legisla- 

 tion of this nature resulted from the introduction of the 

 San Jose' scale into the eastern United States and its 

 threatened general distribution on nursery stock. To 

 meet this emergency, a convention was called in Wash- 

 ington in 1897, composed of the delegates from horti- 

 cultural societies, nurserymen's associations, state 

 agricultural boards, agricultural colleges and experi- 

 ment stations a large and representative body of men. 

 After full discussion a bill was drafted, the primary 

 object of which was the control of domestic nursery 

 stock, but which provided also for the inspection of 

 foreign nursery stock. While this measure received 

 the endorsement of the convention, and was submitted 

 to Congress, the different interests were not fully 

 agreed as to the desirability of all its features, and it 

 was not heartily pushed and was ultimately dropped 

 with the idea of replacing it by a more suitable bill. 



During succeeding years, a number of bills covering 

 the same general subject were introduced at the differ- 

 ent sessions of Congress, and some of these were 

 reported favorably from the Committee on Agriculture, 

 but the opposition of Importing nurserymen prevented 

 any of these measures ever reaching a very advanced 

 stage. In the meantime, various conferences were held 

 between the entomologists of the different states and
