1911] It is good to have arrived at a point where one can run over facts and figures again and again without detecting a flaw or foreseeing a difficulty.

I do not count on the motors—that is a strong point in our case—but should they work well our earlier task of reaching the Glacier will be made quite easy. Apart from such help I am anxious that these machines should enjoy some measure of success and justify the time, money, and thought which have been given to their construction. I am still very confident of the possibility of motor traction, whilst realising that reliance cannot be placed on it in its present untried evolutionary state—it is satisfactory to add that my own view is the most cautious one held in our party. Day is quite convinced he will go a long way and is prepared to accept much heavier weights than I have given him. Lashly's opinion is perhaps more doubtful, but on the whole hopeful. Clissold is to make the fourth man of the motor party. I have already mentioned his mechanical capabilities. He has had a great deal of experience with motors, and Day is delighted to have his assistance.

We had two lectures last week—the first from Debenham dealing with General Geology and having special reference to the structures of our region. It cleared up a good many points in my mind concerning the gneissic base rocks, the Beacon sandstone, and the dolerite intrusions. I think we shall be in a position to make fairly good field observations when we reach the southern land.

The scientific people have taken keen interest in making their lectures interesting, and the custom has grown of
