If neither equipment has been purchased nor repairs made to a vessel while at a foreign port, an affidavit to that effect is required. If sufficient evidence is produced to show that due to stress of weather or other casualty encountered in the regular course of the voyage the vessel was compelled to put into a foreign port for repairs or equipment or secure such repairs or equipment at the foreign port of destination in order to enable it to return in safety to its American port of desti- nation, duties may be remitted or refunded upon application to the Secretary of the Treasury.

The establishment of foreign trade zones was found to be desirable in Sweden, where the customs duties are on about the same level as in Norway, Finland, Germany, and France, considerably lower than those in Spain and the United States, but higher than those in Denmark, the Netherlands, Switzerland. and Great Britain.

The formalities with their attendant delay to the importer of merchandise would be eliminated within the free zone, and the importer would be able to secure possession of his goods upon proper proof of ownership. Assuming the establishment of free ports in the United States and the same freedom which attends the movement and handling of cargo in free ports abroad, practically all of the formalities mentioned above under the head of “Procedure with respect to imports and re-
