Acting Master Thomas L. Dornin and Midshipman Alexander M. Mason, having volunteered to accompany me, the evening was passed in preparing the magazine and in explaining in detail to the officers the manner of handling and working them. In filling the tanks I found that I would have 392 pounds to operate with, instead of 400, which I had calculated upon; and to insure them from sinking I had some cork attached to the buoys, which subsequently proved of great advantage.
