In addition to this, the main object of the expedition is to make a complete map of the land lying to the north of Greenland, or, rather, the Archipelago, for it is believed that this region is occupied by an extensive group of islands. Unfortunately there is reason for thinking that the lofty ice-cap which will allow the explorers to reach the northernmost point of Greenland by sledging over the inland ice does not continue in the same way over the islands to the north of Greenland. Both Lieutenant Peary in his observations on the east, and Lieutenant Lockwood on the west, remarked that the land stretching away to the north was in many places bare of ice and snow, and rugged in its character. One reason for this absence of an inland ice-cap here is the fact that these islands to the north lie low in the ocean compared with mountainous Greenland. Hence, in the summer, which is the only season when an advance would be possible, the ice and snow melt to a great extent and leave the land bare. Now in case Lieutenant Peary finds that there is no continuous ice on this northern land, he will skirt around the shore on the ice of the open sea, for this is present winter and summer alike. It is likely that such an advance over the ice-pack will be attended by very serious difficulties, the ice being heaped up in broken and uneven surfaces, with mountains and chasms to baffle the party. There may also be spaces of open water where boats or rafts will have to be used instead of sledges. At any rate, the advance will be made as far as possible, and the land to the north of Greenland studied and mapped as far as may be. It is not the purpose of the expedition to seek the North Pole itself. They may and very probably will get nearer to the Pole than anyone has hitherto done. Lieutenant Peary is confident that he will make the farthest north, and General Greely is inclined to admit this, and told me some days ago in Washington that he should not be surprised if Lieutenant Peary reached 85 deg. north latitude. In any event, an approach to the North Pole will be an incident in the expedition, and not its main object.
