"They," he said. "They're on the boat. I had to watch them night and day. I didn't dast go to sleep. It got too much; I couldn't stand it. I had to get ashore. I'd been waiting for this channel because it was so narrow. I thought the current 'u'd help me get away. I'm a good swimmer."

"A better one never breasted a wave! Take him below. Give him dry clothes and some whiskey, and set a watch over him."

The poor wretch was led away; the crowd drifted after him. Pale and quiet, the captain went back to the chart-room and resumed his slow pacing forth and back.

"I wish tragedies of body and soul would not occur in such beautiful lengths of water," he said at last. "I can never sail through Grenville Channel again without seeing that poor fellow's haggard face and wild, appealing eyes. And after Gardner Canal, there is not another on the route more beautiful than this!"

Two inlets open into Grenville Channel on the starboard going north, Lowe and Klewnuggit,—both affording safe anchorage to vessels in trouble. Pitt Island forms almost the entire western shore—a beautifully wooded one—of the channel. There is a salmon cannery in Lowe Inlet, beside a clear stream which leaps down from a lake in the mountains. The waters and shores of Grenville have a clear, washed green, which is springlike. In many of the other narrow ways the waters are blue, or purple, or a pale blue-gray; but here they suddenly lead you along the palest of green, shimmering avenues, while mountains of many-shaded green rise steeply on both sides, glimmering away into drifts of snow, which drop threads of silver down the sheer heights.

This shaded green of the mountains is a feature of Alaskan landscapes. Great landslides and windfalls cleave their way from summit to sea, mowing down the forests in their path. In time the new growth springs up and streaks the mountain side with lighter green.

Probably one-half of the trees in southeastern Alaska are the Menzies spruce, or Sitka pine. Their needles are sharp and of a bluish green.

The Menzies spruce was named for the Scotch botanist who accompanied Vancouver.

The Alaska cedar is yellowish and lacy in appearance, with a graceful droop to the branches. It grows to an average height of one hundred and fifty feet. Its wood is very valuable.

Arbor-vitæ grows about the glaciers and in cool, dim fiords. Birch, alder, maple, cottonwood, broom, and hemlock-spruce are plentiful, but are of small value, save in the cause of beauty.
