The Scottish Geographical Journal gives 

 some details in regard to Captain Scott's pro- 

 posed Antarctic expedition. The main object 

 would be to attempt to reach the jmle, and 

 with this object two bases would be established, 

 one at McMurdo Sound, and one if possible in 

 King Edward VII. Land. The attack on the 

 pole would be made from one or other of these 

 bases according to circumstances. Three sepa- 

 rate means of traction would be employed — 

 ponies, dogs and motor-sledges. The experi- 

 ence gained by Mr. Shackleton's party would 

 be utilized as far as possible in determining 

 the special circumstances in which each would 

 be employed. Thus, ponies proved suitable for 

 traction over the surface of the barrier, but 

 not for glacial work, for which dogs would be 

 used. Although Mr. Shackleton's motor-car 

 did not prove a success on the soft snow of the 

 barrier, much is hoped of a new type of motor- 

 sledge with which experiments have been re- 

 cently made. Food would therefore be trans- 

 ported to the foot of the glacier either by 

 ponies or by motor-sledges, while the final 

 dash to the pole, once the plateau had been 

 reached, would be made with the help of dogs.
