AN ANTARCTIC MYSTERY

waves, but we got through the mystic-seeming tempest all safe and sound.

Nevertheless, space was thenceforth but imperfectly lighted. Frequent mists came up and bounded our outlook to a few cable-lengths. Extreme watchfulness and caution were necessary to avoid collision with the floating masses of ice, which were travelling more slowly than the Paracuta.

It is also to be noted that, on the southern side, the sky was frequently lighted up by the broad and brilliant rays of the polar aurora.

The temperature fell very perceptibly, and no longer rose above twenty-three degrees.

Forty-eight hours later Captain Len Guy and his brother succeeded with great difficulty in taking an approximate observation, with the following results of their calculations:

Latitude: 75° 17' south.
Latitude: 118° 3' east.

At this date, therefore (12th March), the Paracuta was distant from the waters of the Antarctic Circle only four hundred miles.

During the night a thick fog came on, with a subsidence of the breeze. This was to be regretted, for it increased the risk of collision with the floating ice. Of course fog could not be a surprise to us, being where we were, but what did surprise us was the gradually increasing speed of our boat, although the falling of the wind ought to have lessened it.

This increase of speed could not be due to the current for we were going more quickly than it.
