What to read after The Valley of Silent Men?

Before the railroad's thin lines of steel bit their way up through the wilderness, Athabasca Landing was the picturesque threshold over which one must step who would enter into the mystery and adventure of the great white North. It is still Iskwatam-the "door" which opens to the lower reaches of the Athabasca, the Slave, and the Mackenzie. It is somewhat diffi- cult to find on the map, yet it is there, because its history is written in more than a hundred and forty years of romance and tragedy and adventure in the lives of men, and is not easily for- gotten. Over the old trail it was about a hundred and fifty miles north of Edmonton. The railroad has brought it nearer to that base of civilization, but beyond it the wilderness still howls as it has howled for a thousand years, and the waters of a contin- ent flow north and into the Arctic Ocean.
