yet reached our rice areas. It is well recognized that straw and hulls provide 
a dangerous channel of introduction for these rice pests. 
Without disturbing the restrictions already in existence under other quar- 
antines, this quarantine aims to secure additional protection against foreign 
pests by prohibiting or restricting the use of certain packing materials con- 
sidered on good grounds to involve danger of pest introduction when these 
materials are used as packing in connection with ordinary commercial 
shipments. 
In addition to the rice straw and rice hulls mentioned, leaves of plants, 
forest litter, and soil containing vegetable matter are potentially such danger- 
ous carriers of plant pests that their use for packing purposes is likewise 
prohibited. These materials, however, are so rarely used as packing, and safe 
substitutes are so universally available, that their exclusion is of entirely 
negligible importance from the commercial standpoint. 
The remaining items in the prohibited list (sugarcane, corn and related 
plants, cotton, and bamboo) are already covered by specific quarantines and 
are included here merely that all packing materials may be dealt with 
together. 
Concerning the restricted list it will be noted that the materials here 
included are required to be free from plant pests, and are made subject to 
inspection, the inspector being authorized to prescribe such treatment or 
disposition as may be necessary in the interests of safety. 
A considerable number of widely used packing materials, such as excelsior, 
paper, sawdust, ground cork, charcoal, and various other materials, which, 
because of their nature or process of manufacture are unlikely to transport 
plant parasites, are not covered by this quarantine. 
It is believed that under this quarantine the necessary protection has been 
provided with the least possible restraint or interference with commercial 
practices.

hearing required thereby having been duly held, notice is hereby given as 
follows :
