But then in walking you are bounded by every sea and river, and in a common sailing-boat you are bounded by every shallow and shore; whereas, I was in a canoe, which could be paddled or sailed, hauled, or carried over land or water to Rome, if I liked, or to Hong-Kong. The wind was fair again, and up went my sail. The reaches got wider and the water more salt, but I knew every part of the course, for I had once spent a fortnight about the mouth of the Thames in my pretty little sailing-boat, the Kent, alone, with only a dog, a chart, a compass, and a bachelor's kettle. The new steamer Alexandra, which plies from London daily, passed me here, its high-terraced American decks covered with people, and the crowd gave a fine loud cheer to the Rob Roy, for the newspapers had mentioned its departure. Presently the land seemed to fade away at each side in pale distance, and the water was more sea than river, till near the Nore we entered a great shoal of porpoises. Often as I have seen these harmless and agile playfellows I had never been so close to them before, and in a boat so small as to be almost disregarded by them, wily though they be. I allowed the canoe to rock on the waves, and the porpoises frequently came near enough to be struck by my paddle, but I did not wage war, for a flap of a tail would have soon turned me upside down. After a pleasant sail to Southend and along the beach, the wind changed, and a storm of heavy rain had to be met in its teeth by taking to the paddle, until near Shoeburyness, where I meant to stop a day or two in the camp of the National Artillery Association, which was assembled here for its first Prize shooting. The Royal Artillery received us Volunteers on this occasion with the greatest kindness, and as they had appropriated quarters of officers absent on leave for the use of members of the Council of the Association, I was soon comfortably ensconced. The camp, however, in a wet field was moist enough; but the fine tall fellows who had come from Yorkshire, Somerset, or Aberdeen to handle the 68-pounders, trudged about in the mud with good humour and thick boots, and sang round the camp-fire in a drizzle of rain, and then pounded away at the targets next day, for these were volunteers of the right sort. As the wind had then risen to a gale it seemed a good opportunity for a thorough trial of the canoe in rough water, so I paddled her to a corner where she would be least injured by being thrown ashore after an upset, and where she would be safe while I might run to change clothes after a swim. The buoyancy of the boat astonished me, and her stability was in every way satisfactory. In the midst of the waves I even managed to rig up the mast and sail, and as I had no baggage on board and so did not mind being perfectly wet through in the experiments, there was nothing left untried, and the confidence then gained for after times was invaluable.
