To certain members of the fleet the awakening in the chilly morning air, with fog rising from the water and drifting through the slender spires of balsam and spruce, was the reverse of inspiriting, and the uncertainty as to the course of the river below did not tend to create an irresistible eagerness for farther rapids and farther wettings. The sun however, soon drove away the mist, dried the heavy dew from boats and equipments, and gradually, as the river dimpled in the sunlight and rushed brimming past in a swift deep current, it resumed its attractiveness and, as soon as clothing was dry enough to put on, every man was eager to begin the day's adventures, and get it comfortably wet again. Single file should be the order of procedure in a rapid river where there is any question as to the width of unobstructed channel. On sighting a rapid whose foot cannot be clearly seen from its head, some one should reconnoitre, and after noting the bearings of the current, should lead the way, the rest of the fleet following at safe intervals and taking prompt warning from his example in case he comes to grief. As a general rule the water is deepest near the _concave_ shore. The reason is obvious. Each general shore-line of a crooked stream is a series of points and bays modified by a hundred varying conditions. Every point tends to deflect the current toward the opposite shore, and where the strongest current is, there is ordinarily the deepest water. Where the stream breaks into rapids the same rule holds good, but is liable to endless modifications from boulders and rocks of all shapes and sizes. Nevertheless it may be assumed that it has been trying for untold ages to shape its channel according to nature's rule, and it will be found in most cases to have attained a reasonable success. At the head of a rapid the white broken water is almost invariably V shaped, the apex pointing down stream. Between the arms of the V the water is comparatively smooth, and dark. Along the arms and below the apex is white water, thrown up more or less into waves. It is generally the safest course, barring casual rocks which may put in an appearance anywhere, to head directly for the apex of the V, keeping in unbroken water as long as possible. Then trust to luck and a quick eye and hand to avoid the rocks which come too near the surface. Nothing but experience can teach one to recognize these, and even recognition does not always imply the ability to avoid disaster.
