4.) VAN. have dosed himself with quinine, and given himself up to the fever of the Brazilian interior. As it was, grimly telling himself that he couldn't afford to be sick, he swallowed a mouthful or two of turtle meat crisped over the coals, washed it down with a draught of river water, and paddled out into the stream. Fortunately he had reached a comparatively easy stretch with a sluggish current, and weak as were the strokes of his paddles, Van was enabled to make con- siderable headway. Then, too, the sun was partly veiled in a soft misty haze not unlike that of a New England October, and a cooling breeze blew up the river, tempering the intense heat. At some little distance ahead Van saw in the very middle of the stream a tall basaltic rock or column, which at a nearer approach he discovered to be of a dull reddish color not unlike porphyry. Around its base the river ran with considerable force, yet so hard was the formation that there was not the least appearance of its having been worn by the action of the water. Comilcbooks:;com
