As in every part of the equipment, modifications had to be made in the circular Willesden-drill tents. To facilitate their erection in the perpetual winds they were sewn permanently on to the five bamboo poles, instead of being thrown over the latter previously set in position. Thus the tents opened like large conical umbrellas. A rawhide loop was fixed to the middle one of the three windward legs and, when raising a tent during a high wind, it was the usual thing for a man to be inside gripping the loop to pin down the windward legs and at the same time, kicking out the two leeward legs. On hard surfaces, holes were dug to receive the ends of the poles; at other times they were pressed home into the snow by the man inside the tent.
When pitched, the tent was held down by blocks of snow or ice, helped by spare food-bags, which were all piled round on a broad flounce. Ventilators, originally supplied with the tents, had to be dispensed with on account of the incessant drift. The door of the tent was an oval funnel of burberry material just large enough to admit a man and secured by a draw-string.
Strips of calico and webbing were sewn over the insides of the light tents to strengthen them for sledging in the summer. For heavy weather we also had japara sail-cloth tents with Willesden canvas flounces. These gave one a feeling of greater security and were much more wind-proof, but unfortunately twice as heavy as the first-mentioned.
A floor-cloth of light Willesden canvas covered the surface of snow or ice in the interior of the tent; performing when sledging the alternative office of a sail.
In order to cut snow, neve or ice to pile on the flounce, a pick and spade had to be included in the sledging equip meet. As a rule, a strong, pointed shovel weighing about six pounds answers very well; but in Adelie Land, the surface was so often wind-swept ice, polished porcelain-snow, or hard neve that a pick was necessary to make any impression upon it. It was found that a four-pound spade, carefully handled, and a four-pound miner's pick provided against all emergencies.
Our sledges were similar to those of other British Antarctic expeditions; of eleven- and twelve-foot lengths. The best were Norwegian, made of ash and hickory. Others built in Sydney, of Australian woods, were admirably suited for special work. Those made of mountain-ash had the advantage of being extremely light, but the runners wore out quickly on ice and hard neve. Sledges of powellized spotted gum were very strong and stood plenty of rough usage, but were heavier than those procured in Norway. A decking of bamboo slats secured by copper-wire to the crossbars was usually employed.
A light bamboo mast and spar were fitted to each sledge. Immediately in front of the mast came the "cooker-box," containing in respective compartments the primus and a bottle of spirit for lighting it, as well as spare prickers, openers and fillers for the kerosene tins, repair outfits and other odd articles. The cooker-boxes were of Venesta board, with hinged lids secured by chocks and overlapped by japara cloth to exclude as much drift-snow as possible. An instrument-box was secured to the sledge near the rear and just forward of a Venesta or aluminium tray on which the kerosene contained in one-gallon tins was carried. In several cases the tray was widened to receive as well a case containing a dip-circle. Rearmost of all was a wooden crosspiece to which the shaft of the sledge-meter was attached through a universal joint. On the middle section of the sledge between the cooker-box and instrument-box, sleeping-bags, food-bags, clothes-bags, tent, alpine rope, theodolite legs, and other articles, were arranged, packed and immovably stiffened by buckled straps passing from side to side.
Sledging harness for both men and dogs was constructed of canvas. In the former case, a wide belt of triple thickness encircled the body at the hips, sewn to braces of narrower strips passing over the shoulders, while hauling-rope was attached to the belt behind. The strength of the whole depended on the care bestowed in sewing the parts together, and, since his life might depend upon it, no one made anything else but a thorough job of his harness.
Ninnis and Mertz ran a tailoring business for the dogs, who were brought one by one into the outer Hut to be measured for harness. After many lengths had been cut with scissors the canvas bands were put through and sewn together on the large sewing-machine and then each dog was fitted and the final alterations were made. The huskies looked quite smart in their "suits".
Upon the primus heater, alone, did we rely for cooking the meals on sledging journeys. First used for purposes of sledging by Dr. Nansen in his journey across Greenland, the primus is only economically managed after some practice. To light a primus in a draughty tent at a low temperature calls for some forbearance before one is a thorough master of the art. A sledging cook will often make a disagreeable faux pas by extinguishing the primus in the preparation of hoosh. This is most readily done by lowering too quickly the outside cover over the rest of the cooker. Fumes of vaporizing kerosene soon fill the tent and when matches are found, the cooker pulled to pieces, the primus relighted and the choking vapours have cleared, one is apt to think that all is well. The hoosh is quite as successful as usual, but the cocoa, made from water in the annulus, has a tincture of kerosene which cannot be concealed.
