The South Polar Times

At the Midwinter Feast, Capt. Scott was presented with a new edition of the South Polar Times, a magazine of anonymously contributed articles, poems, and miscellany which had been initiated on the Discovery Expedition (Scott's first) back in 1902 as a way to keep people occupied through the long dark Antarctic winter. The Terra Nova edition was edited and typed up by Cherry, illustrated by Bill, and bound in sealskin by Bernard Day. Scott wrote:

Except for editorial and meteorological notes the rest is conceived in the lighter vein. The verse is mediocre except perhaps for a quaint play of words in an amusing little skit on the sleeping-bag argument; but an article entitled ‘Valhalla’ appears to me to be altogether on a different level. It purports to describe the arrival of some of our party at the gates proverbially guarded by St. Peter; the humour is really delicious and nowhere at all forced.

... Yes, it appears they wrote their own fanfic.

To the best of my knowledge 'Valhalla' doesn't explain how 'some of our party' ended up arriving at the Pearly Gates, and I'd bet the author wouldn't have dreamed up something as dreadful as what was to play out within the year, but all the same ...

Anyway, I suspect the 'sleeping bag argument' refers to a poem attributed to the expedition's photographer, Herbert Ponting, outlining preferences on how to orient one's reindeer-skin sleeping bag:

On the outside grows the furside. On the inside grows the skinside.
So the furside is the outside and the skinside is the inside.
As the skinside is the inside (and the furside is the outside)
One ‘side’ likes the skinside inside and the furside on the outside.
Others like the skinside outside and the furside on the inside
As the skinside is the hard side and the furside is the soft side.
If you turn the skinside outside, thinking you will side with that ‘side’,
Then the soft side furside’s inside, which some argue is the wrong side.
If you turn the furside outside – as you say, it grows on that side,
Then your outside’s next the skinside, which for comfort’s not the right side.
For the skinside is the cold side and your outside’s not your warm side
And the two cold sides coming side-by-side are not the right sides one ‘side’ decides.
If you decide to side with that ‘side’, turn the outside furside inside
Then the hard side, cold side, skinside’s, beyond all question, inside outside.

Another entry was an account of the Exciting Adventure of the Return of the Depot Party, rendered in 'hieroglyphics', which is to say some narrative illustrations in quasi-Egyptian style with 'translations' in only-just-decipherable phoenetics. I like to think this was devised to get maximum amounts of timekilling out of the SPT, which not only provided occupation for the authors but would get passed around in the coming weeks as people read what everyone else wrote.
