There are two or three conjectures to account for the disappearance of this colony. One is that they were all murdered by the Skroeellings. But where are their bones? Besides, the colonists numbered from fifteen to twenty thousand, and were much superior to the natives in size, strength, intelligence and knowledge of war. Graah, a Danish navigator who came in search of them in 1828, believes that they were carried off bodily by the English after the ravages of the "black death" in England, to repair the waste of human life, citing a treaty of 1433 in which England was charged with abducting Danish subjects for that end. Another theory is that the Frisian king Zichmni carried them off captive. Pope Nicholas asserts this outrage as a fact in a bull in 1448. But Zichmni is as uncertain a personage in history as Demigorgon; and the good popes were not so infallible as to matters of general news before the establishment of telegraph and postal service as they are now. Mr. Dalton Dorr, who accompanied Hayes, tells me that among the Esquimaux there is a tradition that a colony of foreigners once owned the land, and about five centuries ago emigrated in a body northward, crossing the Mer de Glace--that they found an open sea, and somewhere within the eternal rampart of snow and ice now dwell securely by its shores. As early as 1500 the migratory Skroeellings told of this colony far to the north-east. These rumors possessed substance enough to warrant the expeditions from Denmark, which have all been directed to the eastern coast. Graah heard from his guides of a strange people with high features, hoarse voices and large stature living beyond the limits passed by Europeans. Here is a mystery surely worth finding out--a people exiled from their kind for centuries living at the Pole--something better worth search than even Franklin's bones. To give it reality, too, we must remember how many Arctic explorers have caught sight, as they thought, of an open sea near the Pole--a sea with strong, iceless swells, and on whose shores warm rains fell. Nobody need suggest that these people would probably, after our search, not be worth looking for. What shall we do with the North-west Passage when we have found it? R. H. D.
