Nothing was heard from this for about three weeks, but about that time I was informed that one of the vessels of the blockading fleet off the mouth of the James River had discovered the float, and putting out her drag-rope, had caught the air-tubes and thus effectually disabled the vessel from doing any harm, and no doubt drowning all who were on board of her.

This incident, and the peculiarity of the machine, was duly discussed in the newspapers at that time, who stated that "by a mere accident the Federal fleet off James River had been saved from destruction"—but I knew much better, and that the real credit of the discovery was due to a lady of my own force. The efficient manner in which this work was performed was of great service to the nation, and sustained the reputation of the Secret Service Department, as being an important adjunct in aiding the government in its efforts to suppress the rebellion.

I noticed on joining the little crowd that had gathered around him, that the fellow stuttered amazingly, which fact, together with his imperturbable gravity, seemed to be the secret of his always having a good audience about him to listen to his stories and to enjoy his droll humor. I was struck with the man's appearance at first sight and at once concluded that, unless I was much deceived in him, he was a man whom I could use to good advantage, and I determined to ascertain who he was and where he belonged.

Turning to a soldier at my side, I inquired the man's name. Looking at me as though surprised at my ignorance, he answered:
