The steamship companies put on special details of guards to watch the vessels from the moment they entered port until they sailed again. We resumed patrolling the river in various disguises. Fay’s swift motorboat had disappeared, but there were plenty of others, and the men of the Bomb Squad suffered real hardship in all sorts of inclement weather. It seemed as though every item of cargo was watched as it passed into the hold, and every stranger about the piers carefully followed, but there was absolutely nothing to excite suspicion. So we returned to our sugar theory and the Chenangoes. I mentioned the fact that they were a floating tribe in more senses than one, and that the same man rarely came back twice for employment. A few familiar faces, however, could occasionally be spotted in the crowd at work loading the lighters. We made it our business to study these steady workers and found them for the most part a harmless lot of Scandinavians. Those who came, worked once, and vanished, were of all nationalities, with a considerable German representation. Some of them used to come from Hoboken, and by a process of elimination we found that certain of the Hoboken delegation were sailors from the idle North German Lloyd and Hamburg-American ships. We followed them and asked enough questions about them to learn the entire history of any civilized people, but nothing in the form of legal evidence resulted. A friend who knew the methods taught in the Wilhelmstrasse for destroying property said it would be futile for us to follow those men anyway, for the destroying agent himself rarely knows the men higher up, the real conspirators. So it began to look as if even the arrest of a guilty Chenango would not supply the background necessary to picture the bomb system in its entirety.
