You may be sure I utilized Whinney's scientific ingenuity and it is to him I owe two innovations which contributed greatly to our success. One of these was the magnetic bowsprit, highly sensitized by induction-coils run from the exhaust of our 20 h.p. Tutbury engine; the other was the thermal water-line, the temperature of which could be raised to 180 degrees by turning a switch which connected with our storage batteries. Both of these inventions worked perfectly. Thanks to the bowsprit the problem of steering our svelte craft, about which Triplett had expressed some doubts, became a simple matter. Left to herself she invariably came up into the north and as that was the direction we wished to go all was well. The thermal water-line made passage through all but the thickest ice comfortable and easy. For many years the Kawa had had no water-line whatever so that we were uncertain how she would behave. The new one consisted of a thin layer of copper fastened to the elm siding, underneath the seal skin. I like to think that the little Kawa behaved so nobly because she knew her water-line was not visible. Thus we arrived at a type of construction which gave us the strength and elasticity of a water-tight basket. What we had lost in rigidity we gained in feather-like lightness. Before her engines were installed the Kawa floated on the surface like a toy balloon. When loaded, as she usually was, she drew two-feet-six. The installation of the engine and stowing of stores also had a tendency to stabilize the hull and keep her masts pointing upward which was a distinct advantage. In addition to these marine features it was necessary to consider the eventuality of encountering solid, impenetrable ice in the region of the pole, ice through which even the thermal water-line would not make it possible for us to melt our way. Authorities agree that such ice may be expected north of eighty-six, even though we planned to time our arrival in that vicinity for mid-summer when, as is well known, the weather is extremely hot. This is the fascination of Arctic travel; one never knows what to expect. Our problem, then, was to make the Kawa equally at home on the floe or in the open leads, a glorified sea-sled. My previous experience with the various types of sledges convinced me that for my purpose they were useless. My object was to take the Kawa to the Pole. Then why not make the Kawa herself a sled? I recognized instantly the feasibility of my scheme, which consisted of folding guide-runners framed of carefully selected greenheart. When not in use these runners extended horizontally along the counter, giving my little craft a singularly bird-like appearance. Incidentally they formed convenient luggage carriers similar to those attached to the running boards of automobiles and, in fair weather, could be used as piazzas or sleeping porches covered with a high pile of bear-skins to make occupancy easy.
