To these masts we attached a sail made of our shirts-doing this with some difficulty, as here we could get no assistance from our prisoner whatever, although he had been willing enough to labor in all the other operations. The sight of the linen seemed to affect him in a very singular manner. He could not be prevailed upon to touch it or go near it, shuddering when we attempted to force him, and shrieking out, _“Tekeli-li!”_ Having completed our arrangements in regard to the security of the canoe, we now set sail to the south-southeast for the present, with the view of weathering the most southerly of the group in sight. This being done, we turned the bow full to the southward. The weather could by no means be considered disagreeable. We had a prevailing and very gentle wind from the northward, a smooth sea, and continual daylight. No ice whatever was to be seen; _nor did I ever see one particle of this after leaving the parallel of Bennet’s Islet._Indeed, the temperature of the water was here far too warm for its existence in any quantity. Having killed the largest of our tortoises, and obtained from him not only food but a copious supply of water, we continued on our course, without any incident of moment, for perhaps seven or eight days, during which period we must have proceeded a vast distance to the southward, as the wind blew constantly with us, and a very strong current set continually in the direction we were pursuing. _March 1st_. {*7}-Many unusual phenomena now—indicated that we were entering upon a region of novelty and wonder. A high range of light gray vapor appeared constantly in the southern horizon, flaring up occasionally in lofty streaks, now darting from east to west, now from west to east, and again presenting a level and uniform summit—in short, having all the wild variations of the Aurora Borealis. The average height of this vapor, as apparent from our station, was about twenty-five degrees. The temperature of the sea seemed to be increasing momentarily, and there was a very perceptible alteration in its color.
