If motors break down temporarily you will have time for repairs.

If motors break down irretrievably, take 5 weeks’ provision and 3 gallons extra summit oil on 10 foot sledge and continue South easy marches.  Arrange as best you can for ponies to overtake you three or four marches due South One Ton Camp.  Advance as much weight (man food) as you can conveniently carry from One Ton Camp, but I do not wish you to tire any of party.  The object is to relieve the ponies as much as possible on leaving One Ton Camp, but you must not risk chance of your tracks being obliterated and pony party missing you.

On October 23 I wrote my final letters to my wife and friends lest I should get back to Cape Evans after the departure of the “Terra Nova”:  we had by now decided that another winter was imperious, and as far as possible those who were likely to remain a second winter wrote to this effect, and left their letters in Simpson’s charge.  Before my departure with the motors I also spent some time with my leader, and he gave me all his instructions to the various parties to read.

They are so explicit and comprehensive that I may well append certain of them here, for they clearly show how Scott’s organisation covered the work of the ship, the base, the western party, the dog teams, and even the arrangements for Campbell’s party.

I.—­INSTRUCTIONS FOR COMMANDING OFFICER, “Terra Nova.”

October, 1911.

The expedition suffered a considerable loss of ponies in March, but enough remain to carry out the Southern Plan, under favourable circumstances.

This loss and experience with the remaining animals have decided me to start the Southern journey at a later date than originally intended.

As at present arranged the Southern Party leaves at the end of this month (October), and it is estimated that if all goes well the earliest date at which the most advanced party can return to McMurdo Sound is March 15.

As it is probable the ship will be obliged to leave the Sound before this party has returned, arrangements have been made to pass a second winter at Cape Evans, and as is clearly desirable, the Scientific Staff will remain to continue their work.

If fresh transport is brought by the ship, other members of the Expedition will remain to work it, and it is probable that an attempt will be made to cross the Barrier in a S.S.E.ly direction in 1912-13.

The ship must be prepared to return to the Sound in 1912-13 to relieve those that remain for the second winter.

Details concerning past events can be learned from the bearers of these instructions.

In all that follows I want you to understand clearly that you should proceed in accordance with your judgment rather than the letter of these instructions, where the further information you possess may cause it to appear more expedient.
