The Rhine suddenly narrows soon after leaving the Boden See, or Lake Constance as we call it, but the banks again open out till it is a mile or two in breadth. Here and there are grassy islands, and you may notice, by long stakes stuck on the shallows, which tremble as the water presses them, that the channel for steamers is very roundabout, though the canoe will skim over any part of it comfortably. Behind each islet of tall reeds there is a fishing-boat held fast by two poles stuck in the bottom of the river; or it is noiselessly moving to a more lucky pool, sculled by the boatman, with his oar at only one side,--rather a novel plan,--while he pays out the net with his other hand. Rudely-made barges are afloat, and seem to turn round helplessly in the current of the deeper parts, or hoist their great square sails in the dead calm--perhaps for the appearance of the thing--a very picturesque appearance, as the sail has two broad bands of dark blue cloth for its centre stripes. But the pointed lateen sail of Geneva is certainly a more graceful rig than the lug, especially when there are two masts, and the white sails swell towards you, goosewinged, before a flowing breeze. The river has probably a very uneven bottom in this part, for the water sometimes rushes round in great whirlpools, and strange overturnings of itself, as if it were boiling from below in exuberant volume with a gushing upwards; and then again, it wheels about in a circle with a sweep far around, before it settles to go onward.[XVI.] [XVI.] These maelstroms seem at first to demand extra caution as you approach, but they are harmless enough, for the water is deep, and it only twists the boat round; and you need not mind this except when the sail is up, but have a care _then_ that you are not taken aback. In crossing one of these whirlpools at full speed it will be found needless to try to counteract the sudden action on your bow by paddling against it, for it is better to hold on as if there were no interference, and presently the action in the reverse direction puts all quite straight. On the borders of Switzerland the German and French tongues are both generally known at the hotels, and by the people accustomed to do business with foreigners travelling among them. But in your course along a river these convenient waiters and polyglot commissionaires are not found exactly in attendance at every village, and it is, therefore, to the bystanders or casual loungers your observations must be addressed. Frequent intercourse with natives of strange countries, where there is no common language between them and the tourist, will gradually teach him a "sign language" which suits all people alike. Thus, in any place, no matter what was their dialect, it was always easy to induce one or two men to aid in carrying the canoe. The _formula_ for this was something in the following style.
