Meanwhile, we continued to potter along at ten knots, as though we had seen nothing and had not so much as the ghost of a suspicion that submarines were in our neighbourhood. There was but one, so far as I could see; and indeed until that moment we never suspected the Russians of having any in those seas, although vague rumours--which we had never been able to substantiate--had reached us of submarines having been brought overland to Port Arthur from Petersburg in sections. With my eyes glued to my binoculars, and my binoculars focused steadily upon that small pole-like object protruding a bare two feet above that shimmering, silvery sheen of water, I directed the signalman near me to ring down the order to the engine-room to "Stand by"; and then to fetch our wireless operator to me. In a few words I explained the situation to this youngster, when he came, and gave him his orders, while the sounds of Hiraoka's preparations came to my ears. Suddenly, as I watched the periscope every moment becoming more distinct, I noticed that the ripple of foam about it was steadily lessening, and presently it disappeared altogether. The submarine had evidently stopped her engines, and was lying in wait, either to torpedo us as we passed, or to permit us to pass on unsuspecting, and then get in her work upon the transports. It was a bit of luck which I had not dared to hope for, and I instantly made my plans. Steadily the _Kasanumi_ held on, as though utterly unsuspecting, steering a course which, if continued, would take us athwart the submarine's hawse at a distance of about three hundred yards, or less than half the effective range of her torpedo. Was she stealthily altering her position under water, turning her bows toward us, so as to torpedo us the moment we should arrive within range, or was she trusting that her presence was undetected, and waiting patiently for the moment when we should cross her bows as she lay? The latter, I believed, for she could not cant toward us without going either ahead or astern, and she could not do either without her periscope raising a ripple; and I was certain that nothing of that sort had happened. I determined to risk something, after all, to put that submarine out of action, and so held steadily on. At length we arrived so close that I could see the periscope almost as distinctly without the glasses as with them, and still intently watching it, I laid my hand on the engine-room telegraph, carefully estimating the steadily decreasing distance which separated us from moment to moment.
