Peary's concern as regards this big hole in the ice-pack is set forth further on page 265, as follows: "The entire region through which we had come during the last four marches was full of unpleasant possibilities for the future. Only too well we knew that violent winds, for only a few hours, would send the ice all abroad in every direction. Crossing such a zone on a journey north is only half the problem, for there is always the return to be figured on. Though the motto of the Arctic must be 'Sufficient unto the day is the evil thereof,' we ardently hoped there might not be violent winds until we were south of this zone again on the return."

From this it is apparent that Peary realized fully the permanent character of this Phlegethon over which he was traveling. With astonishing persistency, he refers again and again to this particular locality. Quoting from page 303, when on his return march, he says: "There was one region just above the 87th parallel, a region about fifty-seven miles wide, which gave me a great deal of concern until we had passed it. Twelve hours of strong wind blowing from any quarter excepting the north would have turned that region into an open sea. I breathed a sigh of relief when we left the 87th parallel behind."

And, as though the Phlegethon had not already been sufficiently described, on page 307 we find recorded: "Inspired by our good fortune we pressed on again completing two marches, and when we camped we were very near the 87th parallel. The entry that I made in my diary that night is perhaps worth quoting: 'Hope to reach the Marvin Igloo (86° 38ʹ) to-morrow. I shall be glad when we get there on to the big ice again. This region here was open water during February and the early part of March and is now covered with young ice which is thoroughly unreliable as a means of return. A few hours of a brisk wind east, west, or south, would make this entire region open water for some fifty to sixty miles north and south, and an unknown extent east and west. Only calm weather or a northerly wind keeps it practicable.'"

Absolute Proof of Cook's Claim

From the foregoing it is self-evident that Peary's observations by sextant could not be more corroborative of Cook's latitude than that the Phlegethon is proof of the existence of a glacial island between the same two parallels traversed by both explorers. Cook had discovered the cause, and Peary followed to discover the effect of that cause. To one familiar with the conditions of ice-floes in the vicinity of islands in the Arctic the reasons for this are as clear as it would be to the lay mind should it be suddenly announced that on a certain date an astronomer had discovered the head of a comet, which being doubted by rival investigators, might lead to the unhappy discrediting of the original discoverer; but should it be as suddenly announced that a rival astronomer had observed the tail of a comet in the same locality there would quite certainly follow a reversal of public sentiment.

Evidence of His Travels

Of first importance also in proving the existence of new lands discovered by Cook is the evidence derived from the existence of animal life, since Arctic game clings close to the shore line in its search for food. Birds must find their nesting places on lands. Foxes live upon birds and the refuse left in the trails of polar bears and seals. Seals feed upon shrimps and find the chief source of food in waters close to the land. Polar bears in turn feed upon seals, and necessarily are found more numerously about lands or islands.

For this reason we will examine Peary's official narrative of his journey north for evidence of Dr. Cook's discovery of land to within 2° of the North Pole. Having noted Dr. Cook's statement relative to the blow hole of a seal near Bradley Island, we will follow in Peary's trail for corroboration of Cook's journey eleven months previous, and a comparatively short distance westward of Peary's line of march. Referring to Peary's "North Pole" on page 249, while in latitude 85° 48ʹ he records:

"While we were engaged in this business we saw a seal disporting himself in the open water of the lead."

Still farther along, when in latitude 86° 13ʹ, Peary states, on page 252: "Along the course of one of those leads we saw the fresh tracks of a polar bear going west."
