–from Frank Hurley’s account “Shackleton’s Argonauts”–
“The erection of ‘dogloos’ gave us considerable amusement. At first they were strictly utilitarian, but later, when we were able to secure flat slabs of newly-formed ice from a neighbouring lead, the teamsters were as keen to outdo each other in the building of dog-kennels as in the improvement and training of the tenants. The slabs of thin ice could be readily chipped into any desired shape, and cemented together by pouring sea-water over the joinings. Snow, mixed into a mush with sea-water, also made an effective cement, and, in order to secure the dog-chains, it was only necessary to cut a shallow hole in the ice, insert the end of the chain, and pour in a little water. . .
“Crystal villages quickly sprang up around the ship, and the facilities afforded by the endless supply of building material, and the ease with which it could be assembled, afforded much diversion. Architectural design was limited only by the imagination of the builders. The crystal homes were provided with wooden floors and door-frames, windows being unnecessary because a faint, blue light filtered through the walls.”
