But few regions now remain unexplored. 'I'wo parts of our earth, however, in spite of numerous attempts, have not been explored. These two parts lic around the poles. As regards most unknown regions whieh have hitherto been explored there has been this peculiarity, or rather lack of pecu liarity, that there was nothing unusual about their geographic position, as other regions were already C) known which lay in the same latitude and had the <0 same physical conditions. One could thus, with some degree of certainty at least, form an idea of the eon ditions in these regions even before they were traversed. Nevm'theless no considerable area of the globe has been explor'.ld without rewarding us liberally in a scientific way. The polar regions, however, have this peculiarity, that we know no region of the globe whieh lies in a corresponding latitude or under the smue physical conditions. As investigation and science have advanced, scienti fic problems whose solution can be found only in the Arctic and Antarctic regions have arisen. We can study scarcely any branch of the physical sciences, whether meteorology, geology, or physical geography, without meeting great and important problems which await their solution up in the polar regions and con cerning which we now can offer only the vaguest hypotheses. 'l'hose regions which we have hitherto explored have, as a rule, been inhabited, and the foot of the explorer was not the first to tread on its soil. Often, through story and tradition, originating with people who lived in the country, we had arrived at some idea of its conditions and appearance. In the polar regions, on the cont rary, no human foot has set its mark on the white snow, and no human eye has penetrated the icy mists. Since so Itlany scientific problems await their solution in these northern regions, the question as to the value of polar exploration is synonymous with inquiring about the value of any scientific investiga tion. The two polar regions, the Arctic and the Antarctic, have both their peculiar interests. While it is the Arctic region that has most attracted the attention of men, this is due solely to its situation on our hemisyhere. As it is this region which sp("eially concerns us, shall limit myself to its consideration, and first mention the routes by which attempts have been made to reach the north pole. The most successful attempts have been by way of Smith's Sound. For a long time after the American explorers Kane, Hayes, and Hall had reached the highest latitude in this region it was thought that here was the way. Here it was thought they had seen the open polar sea stretching to the north. It was not long, however, before it was found that here also the TIC usual hindrance was encountered; the impenetrable zoI{)CEA ice, coming from the north, carried by a strong polar current.

By this route, Admiral Markham, who took part in the English polar expedition under Nares, reached the highest latitude then attained, proceeding by crevasses on the glacier. He was only twenty-five power, and, with a consumption of about 2% tons of means of sledges over the drift ice as far as 83" 20'.

He was soon the vessel from the neighborhood of the Liakov Is lands, past the north pole, and eventually launch it c------------- - on the waters of the Greenland Sea. Probably no vessel has ever been built for the purpose of Arctic ex ploration with greater foresight or care, or, indeed, of stonter or better materials. In form Dr. N ansen's ship resembles a Scotch buckie boat, only that it is carvel built 11nd rigged as a three-m11sted schooner. Both stem and stern are conlSiderably curved, as in the buckie boats, but by an ingeniouH arrangement the rudder will be entirely submerged, and both it I. and the screw may be raised when necessary and pro I tected from damage in a well. The stern is furnished with two perpendieular :;tern posts-one a propeller post, the other a rudder post. Outside these on both sides are bolted cur ved oak timbers, which give the I: vessel its whaleboat appearance. Between them is the well for both screw and rudder.
