the Secretary of Agriculture shall determine that it is necessary to 
fortiid the import? tion into the United States of any class of nursery 
stock or of any other class of plants, fruits, vei^etaliles, roots, "bulbs, 
seeds, or other plant products from a country or locality where such 
disease or insect infestation exists, he shall promuli^ate such determination, 
specifying the country and locality and the class of nursery stock or 
other class of plants, fruits, vegetables, roots, "bulbs, seeds, or othi^r 
plant products which, in his opinion, should be excluded. Following the 
promulgation of such determination by the Secretary of Af^riculture, and 
until th.~ withdrawal of the sr.id promul(R:ation by him, the importation of 
the class of nurs-^ry stock or of other class of plants, fruits, vegetables, 
roots, bulbs, seeds, or other plant products specified in the said 
promul/ration from th.-^ coiintry and locality th-^r^in named, regardless of 
th*^ use for which thr> same is intended, is hereby prohibited," 
There are two fef^tur-^^s of this section to b-^ especially noted: 
First, it does not covf^r all injurious pests but only those new to or 
not th^retoforp widely prevalent or distributed within end tliroughoixt 
the United States. Second, it is not th^ Secretary's dpt-rmination th^t 
excludes the articles specified; he is authorized merely to determine 
that their exclusion is necessary and to promulgate that determination 
and then th'^ Act of Congress excludes them. None of the products so 
specified is eligible for importation, even under restriction. 
It will be noted in all these Plant Quarantine Act sections that 
jurisdiction of the Secretary extends only to nurs-->i'y stock as defined 
except where other plants and plant products not defined as nursery 
stock may be considered dangerous, such plants end plent products may 
by promulgation of the Secretary be brought under his jurisdiction as 
nursery stock rs contemplated in the Plant Qaarantinp Act. However, 
in no case does the jurisdiction extend beyond nursery stock. 
We are informed by legal authorities that Section 1 means that 
from countries where official inspection exists a p'^rmit must be issued 
by the Secretary for nursery stock when requested. The Secretary can 
prescribe conditions and regulations providing that the nursery sto»k 
must be free of insect pests and plant diseases ?uid subject to departmental 
inspection to determine whether or not they are so free, but the permit 
must be issued. 
Section 7 means that when the S*^cr^tary has promulgated his 
determination thereunder to the effect that the nursery stock or other 
plant products are likely to introdua^ into the United States any tree, 
plant, or fruit disease or any injurious insect new to or not theretofore 
widely prevalent and distributed within and throughout the United States
