Samuel M. Vauclain, president of the Eddystone Ammunition Corporation, and Alba B. Johnson, president of the Caldwell L.ocomotive Works, which owns the buildings occupied by the Eddystone concern, both expressed today their conviction that the catastrophe was the work of "enemy aliens in carrying out a fiendish scheme."

Mrs. Anne Keating, of Trenton, V., today told Federal officials there that on March 11 she had found in a railroad station in Philadelphia a letter addressed to "V. K. In which the writer paid "All ready to blow up Eddystone. Send us help."

In a sheet of white paper, she said, there was a rough sketch of the Philadelphia Navy Yard and the Delaware River and a plan of Chester, Pa. The note contains the signatures of two foreigners. Mrs. Keating asserted.

One official participating in the investigation tonight made this statement: "We are making a thorough investigation, and I do not wish to discuss the results at this time. When the company is satisfied that the facts have been fully determined in arriving at a conclusion as to the cause of the tragedy, a complete statement will be forthcoming. Suffice it to say for the present that there are some suspicious circumstances."  Two hundred of the 110 victims of the pin - | inn have been identified. It is so badly mutilated and charred that identification is difficult. After a fairly complete canvass of the plant's employees, it was unofficially announced today that there were thirty-six unaccounted for. Of the hundred or more men, women, and girls injured, scores are expected to die.
