Soon he ordered the vessel started again, this time on a northeasterly course, and the next morning we were close to land.

Dr. Gresham, who at last had begun to throw off his taciturn mood, told me this was the coast of the almost unsettled province of Cassiar, in British Columbia. Later, as we began to pass behind some rugged islands, he said we were entering Fitz Hugh Sound, a part of the “inland passage” to Alaska. We were now approximately 300 miles northwest of the city of Vancouver.

“Somewhere, not far to the north of here,” added the doctor, “is ‘The Country of the Great Han,’ where Chinese navigators, directed by Huei-Sen, a Buddhist priest, landed and founded colonies in the year 499 A. D. You will find it all recorded in ‘The Book of Changes,’ which was written in the reign of Tai-ming, in the dynasty of Yung: how, between the years 499 and 556, Chinese adventurers made many trips across the Pacific to these colonies, bringing to the wild inhabitants the laws of Buddha, his sacred books and images; building stone temples; and causing at last the rudeness of the natives’ customs to disappear.”

With this my friend left me, upon some summons from the ship’s commander, and I could learn no more.

The region into which we were now penetrating was one of the wildest and loneliest on the North American continent. The whole coastline was fringed by a chain of islands—the tops of a submerged mountain range. Between these islands and the continent extended a maze of deep, narrow channels, some of which connected in a continuous inland waterway. The mainland was a wilderness of lofty peaks, penetrated at intervals by tortuous fiords, which, according to the charts, sometimes extended erratically inland for a hundred miles or more. Back from the coast a few miles, we could see the elevated gorges of the main range filled with glaciers, and occasionally one of these gigantic rivers of ice pushed out to the Sound, where its face broke away in an endless flotilla of icebergs.

The only dwellers in this region were the few inhabitants of the tiny Indian fishing villages, scattered many miles apart; and even of these we saw not a sign throughout the day.

Toward nightfall the doctor had the Albatross drop anchor in a quiet lagoon, and the hydroplane that had been assembled on deck was lowered to the water.

It now lacked two nights of the period of full moon, and the nearly round satellite hung well overhead as darkness fell, furnishing, in that clear atmosphere, a beautiful illumination in which every detail of the surrounding mountains stood forth.

As soon as the last trace of daylight had vanished, Dr. Gresham, equipped with a pair of powerful binoculars, appeared on deck, accompanied by an aviator. He said nothing about where he was going; and, knowing his moods so intimately, I realized it was useless to seek information until he volunteered it. But he handed me a large sealed envelope, remarking:

“I am going for a trip that may take all night. In case I should not return by sun-up you will know something has happened to me, and you are to open this envelope and have Commander Mitchell act upon the instructions it contains.”
