New York, April 18 - The Dutch oil tank steamer La Flandre, which came in today from Antwerp, reported an interesting encounter with the ice filed on April 11 at 9 p.m. at night in latitude 42.02 and longitude 50.07. During the intermittent fog Captain Claude says that La Flandre steamed into a large ice field, which became so thickly packed that the steamer could not penetrate it. The water near the ice filed registered 30 degrees, 2 degrees below fresh water freezing. As far as could be seen from aloft the ice extended in all directions. La Flandre was compelled to put about and steamed for twenty miles to the southward in order to clear the ice field. The temperature of the water on entering the ice pack registered 30 degrees and after leaving the ice pack it arose to 54 degrees.
