THE ROOSEVELT'S NARROW ESCAPE It is perfectly true that the building business is not extensive in the arctic regions, but it is also a fact that if you expect to travel extensively there you must know how to build your own dwellings.

If you neglect to instruct yourself in this direction the chances are that some time or other you will regret it.
Toward the end of the autumn field work, the use of the canvas tents had been discontinued, and snow igloos had been constructed along the line of march.

These were permanent, and were used by the various parties, one after the other.

The new members of the expedition were instructed in the art of igloo building by Marvin, Henson, and the Eskimos.

No man should go into the field in the North in winter unless he knows how to build a shelter for himself against the cold and the storm.
The size of the igloo depends usually upon the number of men in the party.
