Before entering the race of waters, we were requested not to speak, as our talking might diminish the virtue of the medicine; and no one with such boiling eddying rapids before his eyes, would think of disobeying the orders of a "canoe-smasher." It soon became evident that there was sound sense in this request of Tuba's, although the reason assigned was not unlike that of the canoe-man from Sesheke, who begged one of our party not to whistle, because whistling made the wind come. It was the duty of the man at the bow to look out ahead for the proper course, and when he saw a rock or snag, to call out to the steersman. Tuba doubtless thought that talking on board might divert the attention of his steersman, at a time when the neglect of an order, or a slight mistake, would be sure to spill us all into the chafing river. There were places where the utmost exertions of both men had to be put forth in order to force the canoe to the only safe part of the rapid, and to prevent it from sweeping down broadside on, where in a twinkling we should have found ourselves floundering among the plotuses and cormorants, which were engaged in diving for their breakfast of small fish. At times it seemed as if nothing could save us from dashing in our headlong race against the rocks which, now that the river was low, jutted out of the water; but just at the very nick of time, Tuba passed the word to the steersman, and then with ready pole turned the canoe a little aside, and we glided swiftly past the threatened danger. Never was canoe more admirably managed: once only did the medicine seem to have lost something of its efficacy. We were driving swiftly down, a black rock over which the white foam flew, lay directly in our path, the pole was planted against it as readily as ever, but it slipped, just as Tuba put forth his strength to turn the bow off. We struck hard, and were half-full of water in a moment; Tuba recovered himself as speedily, shoved off the bow, and shot the canoe into a still shallow place, to bale out the water. Here we were given to understand that it was not the medicine which was at fault; that had lost none of its virtue; the accident was owing entirely to Tuba having started without his breakfast. Need it be said we never let Tuba go without that meal again? We landed at the head of Garden Island, which is situated near the middle of the river and on the lip of the Falls. On reaching that lip, and peering over the giddy height, the wondrous and unique character of the magnificent cascade at once burst upon us.
