nor can escape from them to other logs, or to wood, bark, or trees. Piling 
such logs with other logs, or placing them on the ground in the open, especially 
on or near barky waste, would not be considered good storage because of the 
common occurrence of insects in such places. 
TREATMENT BEFORE TRIMMING OR WASTE IS REMOVED 
If the Dutch elm disease fungus is present in imported logs it is likely to 
occur in the outer layers of the wood. Hence all untreated trimmings and 
waste would be as dangerous as the logs themselves. Every bit of the imported 
material should go through the treating process. 
TREATMENT 
Treatment is intended to destroy completely the fungus in these logs, as 
well as any insects which might be present. After such treatment the logs are 
no longer regarded as a source of danger and the Department will have no 
interest in their subsequent disposition. 
It is believed that the fungus can be killed rather readily by exposure to 
a temperature of 180° F. or over for at least 2 hours, so that any process which 
would guarantee this minimum for the interior parts of the log would be 
acceptable. Since it takes time for the heat to penetrate, the actual immersion 
period will have to allow for such penetration. Working formulas for treat- 
ment, adapted to fit in with veneer plant facilities and practices, will be 
worked out and approved as rapidly as possible. 
ENTRY UNDER BOND 
This procedure is the only simple plan available under the Plant Quarantine 
Act whereby these elm logs can be allowed entry and yet make it possible for 
the Department to meet its responsibility by keeping them under control and 
supervision at all times until they have undergone treatment. This procedure 
may be regarded as the only safe alternative to an embargo. 
It will be noted that the redelivery bond furnished by the importer to the 
collector of customs enables the importer to obtain custody of the logs for 
treatment at a plant where suitable facilities are available for such treatment. 
If the importer chooses to have the logs treated at a port of first arrival 
where either his own or other such facilities are available, the treatment can be 
given there. But if he elects to have the treatment given at his own or 
other approved plant which is in the jurisdiction of an interior customs port 
of entry, the shipment may be sent I.T. to be released at that port under 
bond for treatment. 
CERTIFICATION OF TREATMENT 
Whether the treatment is given a shipment at the port of first arrival or 
at an interior point, an inspector will be provided by the Bureau of Plant 
Quarantine to certify that the treatment as required by the regulations has 
been given. The inspector will so notify the collector of customs, whereupon the 
collector will cancel the bond and complete the release of the shipment. The 
regulations provide a 20-day period for treatment, but it is expected that 
arrangements will be made in all cases for as prompt treatment as possible 
after arrival. 
PERMIT AND NOTICE OF ARRIVAL 
Attention is called to the necessity of securing from the Bureau of Plant 
Quarantine, in advance, a permit for the importation of each shipment of elm 
logs from Europe, and of submitting a notice of arrival for each shipment at 
the time of entry. These documents constitute the legal means whereby under 
the Plant Quarantine Act the importation may be made under the supervision 
of the Department through the channels provided by the Bureau of Customs.

Acting Chief, Bureau of Plant Quarantine.
