The wind is doubtless the most important cause of the drift, but a more complete examination of the observations than has hitherto been possible will almost certainly bring to light an outstanding effect due to current.

The wind is doubtless the most important cause of the drift, but a more complete examination of the observations than has hitherto been possible will almost certainly bring to light an outstanding effect due to current. The direction of the drift was always a little to the left of the direction of the wind. This is due to the rota- tion of the earth, and a similar deviation to the right of the wind direction was noticed by Nansen during the drift of the Fraiii across the North Polar Basin. The drifts of both the Endurance and the Deutschland in the Weddell Sea show strangely parallel courses up probably now filled up with shelf-ice similar to that of the great Ross Barrier. The various problems raised by the drift of the Endurance which have been touched on above have been considered very fully by Mr. J. M. Wordie, geologist to the expedition, to whose work reference should be made by those interested in the subject. REFERENCES FOR FURTHER READING South, by Sir Ernest Shackleton. (Heinemann.)
