remnants on these elm burl logs, even where bark removal evidently had been 
attempted before shipment. Under these circumstances it seems hopeless to 
export a bark removal complete enough to eliminate these carrier insects from 
the deep crevices of gnarled and twisted burls, and since the presence of such 
insects in any stage, in any number, at any port, is regarded as involving a 
definite danger of further introduction of the Dutch elm disease, this quarantine 
has been revised to exclude all elm veneer logs from European sources.

NOTICE OF QUARANTINE NO. 70 ON ACCOUNT OF THE DUTCH ELM DISEASE 
(REVISED) 
(Approved Dec. 20, 1934 ; effective Jan. 1, 1935) 
Having found that an injurious plant disease, known as the Dutch elm 
disease, due to the fungus Graphium ulmi Schwarz, not heretofore widely preva- 
lent or distributed within and throughout the United States, exists in various 
countries of the continent of Europe, I, Henry A. Wallace, Secretary of Agri- 
culture, pursuant to the provisions of the Plant Quarantine Act of August 20, 
3912 (37 Stat. 315), as amended, have determined that it is necessary to pro- 
hibit or restrict the importation into the United States from the continent of 
Europe of certain plants and plant products hereinafter specified, in order to 
prevent the introduction into the United States of said disease. 
Now, therefore, by virtue of the said Plant Quarantine Act, the public hear- 
ing required thereby having been duly held, notice is hereby given as follows: 
The importation into the United States from the continent of Europe of the 
following articles is prohibited: (a) Seeds, leaves, plants, cuttings, and scions 
of elm and related plants; (b) logs of elm and related plants; (c) lumber, 
timber, or veneer of such plants if bark is present on them; (d) crates, boxes, 
barrels, packing cases and other containers, and other articles manufactured in 
whole or in part of the wood of elm or related plants, if the elm wood or wood 
of related plants is not free from bark. 
Exceptions to the above prohibitions may be authorized for entry under 
permit under such conditions and regulations as the Secretary of Agriculture 
may prescribe, or when the particular article or material has been or is to be 
so treated, prepared, or processed that, in the judgment of the Secretary of 
Agriculture, its unrestricted entry involves no risk of pest introduction. 
The expression " elm or related plants ", as used herein, means plants of all 
species and genera of the family Ulmaceae, including the genera Ulnius, Celt is, 
Zelkova, Ampelocera, Aphananthe, Barbeya, Chaetachne, Chaetoptelea, Giron- 
niera, Holoptelea, Lozanella, Parasponia, Phyllostylon, Planera, Pteroceltis, 
Trema, and all species thereof. 
This notice of quarantine revises and supersedes Notice of Quarantine No. 
70, effective October 21, 1933, and shall be effective on and after January 1, 
1935. 
Done at the city of Washington this 20th day of December 1934.
