Among other names which were furnished us was that of one Chakravarty, whose address was 364 West 120th Street, New York. For more than a fortnight men of the Bomb Squad under Mr. (now Lieut.-Col.) Nicholas Biddle, as special aid to the commissioner, watched that house. They hired a room opposite, where through a slit in the window shade they could keep the doorway under observation. At the hours when working New York leaves its home to make money, and comes home at night having made it, the door was rarely used, but sometimes at mid-forenoon, sometimes in the small hours of the morning, the men on watch saw several dark-skinned individuals pass in and out of the house. The building itself gave no sign of suspicious activity. We were on the brink of war, and as was the case in most of the other houses in the block, an American flag hung draped in the front window. What went on behind the camouflage screen we did not know. Now and then our men, hiding in the shadow of the areaway, would go quietly up into the dark doorway and listen, but the house never gave out a sound. There was certainly no indication that these Hindus were conspiring with the Imperial German Government in dynamite plots. We knew certain East Indians who could be depended upon, and told them to call upon Chakravarty. This ruse failed because Chakravarty never presented to the callers anything but a guileless reception. So far as they could learn his occupation was that of manufacturer of pills; he and a certain Ernest Sekunna constituted the Omin Company, which company packed in aluminum boxes and sold to a limited clientele pills which like most patent remedies were recommended for any ailment from indigestion up or down--if the pill sold, then it was a success. This news did not quiet our impatience, and we decided on a raid.
