On the morning of January 9, 1918, one Dr. W—— voluntarily appeared at the office of the American Protective League, 615 Lyon Building, stating that he was a German and had done considerable intricate work in the Government and that he was anxious to serve our organization. W—— was immediately placed under investigation, and it developed that he was a German alien enemy, and was in the habit of violating his alien enemy permit. It was also discovered that he owned and occupied a houseboat on the East Waterway in the ship-building district, in the prohibited zone on the water front. This place was visited and examined. Our operatives found documents proving that W—— was an alien enemy and a Reserve Officer in the German Army. He had on board the houseboat an extensive chemical laboratory and a complete chemical library in the German language; also technical books on wireless and other matters of military importance. The chemicals were seized, sent to the Immigration Department and examined by a chemist. W—— was placed under arrest, given a hearing, and ordered interned for the duration of the war. It developed that W—— had communicated with S—— and warned him of his approaching arrest, and that S—— had departed north in his boat. The League officers immediately got in touch with their organization in Skagit County, and operatives were detailed to watch for S——. When he came into the Flats, they apprehended and placed him under arrest and seized his boat. On board was found quite an arsenal of assorted makes of guns. The examination took place at the time an opportunity was being given alien enemies to register as such, and this opportunity was given S—— at the Immigration Station. S——, however, maintained that he was an American citizen; he could not produce papers but his explanation was as follows: That he had filed his declaration to become an American citizen and that, by reason of his activities against the law, he had been arrested and sentenced to serve six years in the penitentiary at Walla Walla; that while he was serving out his sentence, the date for him to appear for examination and acquire his second papers had expired, and that on account of his inability to appear, this automatically made him an American citizen. Therefore, he refused to register as an alien enemy. At the conclusion of the hearing, S—— was ordered interned and sent to Utah. S—— had, for the previous six weeks, been hovering around the depot tanks of the Standard Oil Company. From the association of W—— and S—— and the facts that were disclosed in the investigation, there is no question in the minds of the officers of the organization but that they were about to cause an explosion at this plant as well as at one of the shipyards.
