My dear Daniels:
Last Monday afternoon I thought I would try out some of the depth charges that had been supplied in Boston, in the vicinity where I had last seen two submarines their position being too uncertain to risk the loss of one of our two big ones supplied in Queenstown, so I tossed a couple over but nothing happened. On examination it was found that the bouy part did not separate from the mine part readily and also it was found that the reel upon which the distance wire is rove worked stiffly and one of these two causes was probably the reason for their not having functioned. I suggest that everybody be advised as to this and at the next opportunity I am going to separate the bouy from the mine before heaving it overboard and try it that way.
The aforesaid subs were at least four miles off and had evidently been communicating with each other. The rascals ducked as soon as we commenced firing and although I dashed around for a couple of hours or so saw nothing more of them.
