From May 31, when we were in latitude 71° 36′, a point farthest south, to September 16, when we were in latitude 69° 51′ 16″, we steadily and persistently drifted northward. The movement has been extremely slow, and at times we have been stationary, but we have not gone south with northerly winds. This we explain by the fact that new ice forms rapidly in the leads which open behind us, thus closing all the spaces. In a similar manner, but with many more interruptions, and with a much more rapid pace, we have drifted eastward during this time from longitude 87° 33′ 30″ to 82° 22′ 45″. The longitudinal drift, however, has changed with every direction of the wind. From this time until November 19, we drifted southward again, while still continuing our easterly drift. October 15.--We are now able to read our thermometers and other instruments outside without artificial light from 2:30 A.M. to 9:30 P.M. The five hours of night are made so brilliant by the twilight during clear weather that we can read ordinary print all night. We no longer need lamps on board during the day, which is fortunate, for our stock of candles and petroleum is getting low. The snow in the night now assumes a noticeable brightness after a day of sharp sunshine. During the long night, and in the early days of spring when the sun was feeble, the snow was dull and black. The present change to a sort of phosphorescence I have ascribed to a kind of latent retention by the snow of the light of the sun. I have taken much interest in this phenomenon, and have recently made certain tests which seem to confirm my theory. For a number of days I have placed black cloths over certain smooth fields of snow. During the night I have removed these and invariably there has been a dark spot, corresponding to the size of the cloth, while the snow everywhere else was semi-luminous. This, in my estimation, proves that the snow absorbs and retains for a time certain rays of light.
