Several things go to prove that our ration was not enough.  In the first case we were probably not as fit as we seemed after long sledge journeys.  There is no doubt that when sledging men developed an automaticity of certain muscles at the expense of other muscles:  for instance, a sledge could be hauled all day at the expense of the arms, and we had little power to lift weights at the end of several months of sledging.  In relation to this I would add that, when the relief ship arrived in February 1912, four of us were at Cape Evans, but just arrived from three months of the Polar Journey.  The land party, we four among them, were turned on to sledge stores ashore.  This in practice meant twenty miles every day dragging a sledge; a good deal of ‘humping’ heavy cases, from five o’clock in the morning to very late at night; with uncertain meals and no rests.  I can remember now how hard that work was to myself and, I expect, to those others who had been away sledging.  The ship’s party sledged only every other day “because they were not used to it.”  This was extremely bad organization, and in view of the possibility that some of the men might be required for further sledging in the autumn, just silly.

Again, there is the experience of the man-hauling parties of the Polar Journey.  There was, you may remember, a man-hauling party on the way to the Beardmore Glacier.  They travelled with a light sledge but they lost weight on the Barrier ration.  It is significant that they picked up condition when they started the Summit ration, especially Lashly.

The Polar Party and the two returning parties, who were on the Summit ration from the foot of the Beardmore until the end of their journeys, weakened, in Atkinson’s opinion, more than they should have done had their ration been sufficient.  The First Return Party covered approximately 1100 statute miles.  At the end of their journey their pulling muscles were all right, but Atkinson, who led the party, considers that they were at least 70 per cent weaker in other muscles.  They all lost a great deal of weight, though they had the best conditions of the three returning parties, and the temperatures met by them averaged well over zero.

The Second Return Party faced much worse conditions.  They were only three men, and one of the three was so sick that for 120 miles he could not pull and for 90 miles he had to be dragged on the sledge.  The average temperature approximated zero.  They were extremely exhausted.

Scott makes constant reference to the increasing hunger of the Polar Party:  it is clear that the food did not compensate for the conditions which were met in increasing severity.  Yet they were eating rather more than their full ration a considerable part of the time.  It has to be considered that the temperatures met by them averaged far below -10 deg.:  that they did not absorb all their food:  that increased heat was wanted not only for energy to do extra work caused by bad surfaces and contrary winds, but also to heat their bodies, and to thaw out their clothing and sleeping-bags.
