(d) An opinion as to the effect on the transport of goods destined for the enemy which would result from blocking the Corinth Canal with particular reference to the question whether the blocking of the Canal would merely result in prolonging the transit of goods destined for the mg or would effectively prevent the arrival of such goods. 9. It has been pointed out above that the amount of traffic destined for the enemy at present passing through the Canal is negligible. It must, however, be borne in mind that the amount of this traffic may very well increase in the winter months, more particularly if the arrangements which the Italians are making to import oil overland by rail from the Danube break down under the stress of winter weather.
