Astern of us, a medley of sound and steering-signals marks the gateway of the harbour where our followers are striving to drop their pilots and join in convoy; one loud trumpeter is drawing up at speed and showing, by the frequency of her whistle-blasts, anxiety to sight our wake. The lighthouse syren roars a warning of shoal-water out on the landward beam, a raucous discord of two weird notes. These, with the rare mournful wail of our leader, are our guiding sounds, but we have sight now and then of the destroyer escort passing and turning mistily on the rim of our narrowed vision, like swift sheep-dogs folding the stragglers of a scattered flock. The fog, that settled dense and deep as we got under way, shows a little sign and promise of thinning, a small portent that draws our eyes to the lift above the funnel. There is no wind, but our smoke-wrack, after curving with our speed to masthead height, seems turned by light upper draughts to the eastward. The sun has risen and peers mistily over the top of the grey curtain that surrounds us. The day is warming up. Pray fortune, a stout west wind may come out of it all, to clear the muck and give us one good honest look at one another, when we are due for that 'six-point' turn to the south'ard! To keep in station on our pacemaker, we call for constant alterations in the speed--a range of revolutions that rattles up scale and down, like first lessons on the piano, and sets the engineers below to a plaintive verge of tears. The junior officer at the voice-pipe looks reflective, after each order he passes, as though comparing the quality of the reply with the last sulphurous rejoinder. The fog has added to our starting vagaries and postponed a happy understanding, but we shall do better later on when we have gauged and discovered--and pitied--the tiresome vacillations of the _other_ ships! Meantime, as best we can, we chase the sheering hydroplane ahead that seems endowed with every chameleon gift of the classic gods. It vanishes, invisible, in a drift of fog, and though we con a course as steady as a cat on eggs, a clearing comes to show us its white feather broad on the bows and edging off at an angle to dip under the thick of the mist! It drops down to us; we sheer aside and slow a pace, and it lingers and dallies sportively abeam. It slips suddenly ahead, with a rush and a rip, as though, like a child among the daisies, it recalls a parent in advance.
