Rae was now almost directly to the east of the magnetic north pole, the north-seeking end of his compass pointing eight degrees to the south of due west. Breaking camp, he turned toward the magnetic pole. Having a heavy load, he decided to cache his surplus supplies until his return, but did not dare to do so near the Eskimos. The cache was made on a rocky hill several miles inland, and it took some time to make it secure from animals and free from observation by travellers. The cache made, Rae was astonished and angry to find that the Eskimo interpreter, Ouglibuck, was gone. Rae never thought of desertion, but keen-eyed Mistegan caught sight of the Inuit fleeing to the eastward toward the camp of his native cousins. As the speediest of the party, the doctor and the Cree started after him, taking that slow dog-trot with which the Indian runners cover so much ground untiringly. It was a sharp run of five miles before the deserter was overtaken.

Rae says: "Ouglibuck was in a great fright when we came up with him, and was crying like a child, but expressed his readiness to return, and pleaded sickness as an excuse."

The doctor thought it best to diplomatically accept the statement that the deserter was sick, but none the less he deemed it wise to decrease the load hauled by the Eskimo, doing so at the expense of the half-breeds. But it was quite clear that Ouglibuck was more than willing to exchange his conditions of hard field work with scant food for the abundant seal meat and the social company of his own people, which had proved so enjoyable during his brief visit to their igloos.

This prompt action of Rae's tided over the critical phase of the expedition, and the temporary delay indirectly brought about the meeting with other natives, from whom came the first news of the missing explorers. Immediately after renewing his western journey, Rae met a native who had killed a musk-ox and was returning home with his dog-sledge laden with meat. Ouglibuck made his best efforts to reinstate himself in the good graces of Rae by persuading the Inuit stranger to make a journey of two days to the westward, thus lightening the loads of the other sledges. Another Eskimo then joined Rae, anxious to see the white men of whom he had heard from the visitors of the day previous.

The doctor asked his usual question, as a matter of form, as to the Eskimo having seen before any white men or any ships, to which he answered in the negative. On further questioning he said that he had heard of a party of kabloonans (white men), who had died of starvation a long distance to the west.

Realizing the full importance of this startling and unexpected information, Dr. Rae followed up this clew with the utmost energy, both through visits to and by questionings of all Eskimos he could find. He also extended his field efforts, during which cairns were searched and the adjoining region travelled over as far as Beecher River, about 69° N. 92° W. His original work of surveying was now made incidental to a search for Franklin!

Nor must it be thought that these journeys were made without considerable danger and much physical suffering. A half-breed, through neglect of Rae's orders regarding changes of damp foot-gear at night, froze two toes. With a courage almost heroic, this Indian labored to redeem himself by travelling along and by doing all his work for several weeks until he could scarcely stand. Imbued with the importance of his new mission, Rae allowed nothing to stand in his way of adding to his precious knowledge and to the possible chance of tracing the wanderings of the lost explorers. He left the lame man with another half-breed to care for him and to cook the food spared for them. The shiftless character of Rae's men was shown by the fact that the well man not only did not shoot anything but did not even gather saxifrage for fuel, but used scarce and precious grease food for cooking.

Yet the fortitude and pride of the cripple was displayed in the return journey, with the outer joint of his great toe sloughed off, thus making it most painful to walk; as Rae remarks, "He had too much spirit to allow himself to be hauled."

Rae's collected information was as follows:

In 1850 Eskimo families killing seals near King William Land saw about forty white men travelling southward along the west shore, dragging a boat and sledges. By signs the natives learned that their ships had been crushed and that they were going to find deer to shoot. All were hauling on the sledge except one officer. They looked thin and bought a seal from the natives. Late that year the natives found the corpses of about thirty-five men near Montreal Island and Point Ogle, part in tents and others under a boat. None of the Eskimos questioned by Rae had seen the explorers either living or dead. They learned of these matters from other natives, from whom they had obtained by barter many relics of various kinds.
