It was learned that the reports accompanying the set of photographs and "fragments of metal" were not the original reports on the Nebraskan case, made by Lieutenants Towers and McBride, which were received by the State Department last week, but were in the nature of a second set of supplementary reports, based on actual examination of the battered bow of the Nebraskan and the technical examination of the interior of her forward compartment. This examination was made by Lieutenants Towers and McBride, while the Nebraskan was in a drydock at Liverpool. Photographs of the interior and exterior of the steamer's hull were taken by the naval experts.
The "fragments" in question will be analyzed metallurgically for the purpose of ascertaining precisely what metal they contain. Generally speaking, torpedoes are made of a higher grade of metal, within and without, than that used in the construction of mines. The exterior metal of torpedoes consists of nickel steel and copper, and the interior mechanism includes the same kinds of metal and brass. The exterior shell of a mine is generally made of less expensive material, such as galvanized iron, but the interior mechanism and clock-work are of finer metal.
In the examination being conducted by the Navy Department the metallurgical nature of the fragments will be ascertained after their size, shape, contour and character have been very carefully studied by a large number of naval experts who will endeavor to ascertain not only the character of the naval engine of destruction these fragments once fitted, but also the particular portion of torpedo or mine the fragments constituted. These studies and tests are to be conducted partly in the Navy Department, partly at the Washington Navy Yard, partly at the naval proving grounds at Indian Head, Md., and partly at the experimental station at the Naval Academy at Annapolis.
All the naval experts in Washington qualified to have a hand in the tests will be utilized. There are some naval experts outside of Washington, within a few days' reach of the city, who will be summoned here to participate in the examination. It is understood the examination will continue about ten days before any report can be formulated for submission to the State Department.
While this unusual care is being exercised in the tests of the fragments, it is understood that there is nothing in the conclusions thus far drawn in the reports to indicate that the fragments were once part of a mine, and that the reports as they stand indicate that the Nebraskan was hit by a torpedo. This is the conclusion the Administration is expected to draw from the evidence unless the technical examination of the fragments nullifies this evidence.
Dr. Meyer-Gerhard’s Mission
In a cable dispatch from Berlin, via London, dated June 2, 1915, the following complaint of lack of official news from Washington and of means for obtaining it was made known by the German Government:
The German Foreign Office is unable to communicate with Count von Bernstorff, the Ambassador at Washington, except by wireless in plain language, and even this mode of communication is uncertain during periods when the static conditions of the atmosphere are unfavorable.
Reports which reach the newspapers are regarded with suspicion, not only because they come exclusively through British channels, but on account of their contradictory character.
