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. In the "Nansen Cooker," which we used, a maximum result is secured from the heat of the primus. The hot gases from the combustion of the kerosene, before they escape into the outside air, have to circulate along a tortuous path, passing from the hot interior to the colder exterior compartments, losing heat all the time. Thus a hot hoosh is preparing in the central vessel side by side with the melting of snow for cocoa or tea in the annulus. By the combination of "Nansen Cooker" and primus stove one gallon of kerosene oil properly husbanded is made to last for twelve days in the preparation of the ordinary ration for three men. [TEXT ILLUSTRATION] Section through a Nansen Sledging Cooker mounted on the primus The subject of food is one which requires peculiar consideration and study. It is assumed that a polar expedition must carry all its food-stuffs in that variety and quantity which may approximately satisfy normal demands. Fortunately, the advance of science has been such that necessaries like vegetables, fruit, meats and milk are now preserved so that the chances of bacterial contamination are reduced to a minimum. A cold climate is an additional security towards the same end. Speaking generally, while living for months in an Antarctic hut, it is a splendid thing to have more than the mere necessaries of life. Since one is cut off from the ordinary amenities of social existence, it is particularly necessary that equipment and food should be of the very best; in some measure to replace a lack which sooner or later makes itself keenly felt. Explorers, after all, are only mortal.
