The good ship Yucatan steadily ploughed her way along the rock-bound Alaskan coast until, at noon of the second day, she nosed her way into the entrance of that great indentation of the coast known as Resurrection Bay, and finally concluded her own northbound journey at the docks of the town of Seward, which lies at the head of that harbor. Here the voyagers were to change to a smaller vessel, the sturdy little craft called the Nora, which was to carry them still farther northward and westward. The young travellers, although before this they had known Alaska to be a great country, now began to think that they had not dreamed how large it really was, for Uncle Dick advised them that they would need to steam almost a week yet farther before they could arrive at Kadiak harbor.

Once out of Resurrection Bay on their journey to the farther north, they began to see sights strange even to them, long as they had been used to Alaska. Hundreds of sea-lions crowded some lofty rocks not far beyond the entrance to the bay, roaring and barking at the ship as she steamed close in to the rocks, and plunging off in scores as the whistles of the boat aroused and frightened them from their basking in the sun.

Rob’s eyes proved keener than those of his friend, and he was always looking out across the sea in search of some strange object.

“What’s that, Mr. Dick?” he exclaimed, after he had been gazing steadily at the far horizon for some moments.

Uncle Dick hastened to his state-room and returned with a pair of field-glasses.

“That,” said he, “is a whale—in fact, more than one; indeed, I think there is a big school of whales on ahead. We’ll run almost square into them at this rate.”

Sure enough, within the hour they came within plain sight of a number of great black objects which at first seemed like giant logs rolling on the water. All at once there appeared splashes of white water among the whales, and the latter seemed to be much agitated, hastening hither and thither as though in fear. Captain Zim Jones, of the Nora, leaned down from his place on the bridge.

“School of killers in there!” he sang out.

“That’s right,” exclaimed Uncle Dick, handing the glasses to Rob. “Watch close now! Don’t you see those smaller black things swimming along, with tall, upright fins? Those are killers, and they are fighting the whales right now!”

Eagerly the boys took turns with the glasses, watching the strange combat of the sea now going on. Evidently some of the whales were much distressed; one large one seemed to be the especial mark of the enemy, which pursued him in a body.

“Look, look!” cried John. “He jumped almost out of the water. He is as big as a house!”

“I didn’t know anything could hurt a whale, he’s so big!” commented Jesse. “How do they fight a whale?”

“Maybe they poke ’em with that big fin,” said Uncle Dick. “But they do the damage with their jaws. One of them will bite a chunk out of a whale, and as quick as he lets go another will take his place. They come pretty near to eating the whale alive sometimes, although I don’t know that they really kill them very often.”

“Well, I don’t know,” said Rob, who was looking steadily ahead. “There is one right ahead of us who just came up, and he’s acting mighty stupid. See, he’s coming right across the bows. If we don’t look out we’ll hit him. There!”

Even as he spoke there came a heavy jar which almost stopped the ocean vessel. Her steel-shod bow had struck the whale full in the middle of the body.

“Caught him square amidships,” sung out Captain Zim from his station. “I guess we finished what the killers began!”

The great creature lay for an instant stunned on the surface of the water, its vast body bent as though its back were broken. Then as the ship passed on it slowly sank from sight, even as the school of whales, diving and breaching, also fell astern, still pursued by their savage enemies.

“Well,” said Captain Zim, “I’ve sailed these waters thirty years, but that’s the first time I ever struck a whale.”

“I’ve promised these boys plenty of exciting things,” commented Uncle Dick. “But if you don’t mind, I’d rather you wouldn’t run over any more whales. You’ll be taking the keel out of this ship the first thing you know.”

“I see something else!” called Jesse, who was examining the rolling sea studiously with the field-glasses. “See it—right over there about two hundred yards! It looks like a man standing up in the water.”

“Oh, that,” said Uncle Dick, “it’s only a seal.”

“Couldn’t I shoot it?” asked Rob. “I’d like to get its fur.”

Uncle Dick laughed. “You wouldn’t find its hide worth more than a dollar or so, if you got it,” said he. “That’s only a little hair seal. You won’t find any fur seals until you get a good many hundred miles beyond Kadiak. And that’s a good many hundred miles yet from here. Let the little fellow go, and turn the glasses on that big bunch of whale-birds over there. See them flying—there’s a string nearly a mile long.”

“I see them! I see them!” called out Rob. “There are thousands and thousands of them. I’ve seen them before, and one of the sailors told me that there is always most of them where there are whales around. They seem to feed on the same sort of things in the water, someway.”

“There are plenty of things you see up in this country,” said Uncle Dick, as he turned away. “You may have thought Valdez was pretty much all of Alaska, but I’ll show you it is just the beginning.”

“Do they have shipwrecks up here, Uncle Dick?” asked John. “It looks to me pretty rocky along these shores.”

“Don’t talk about shipwrecks!” replied his uncle. “This coast is full of them. I can show you the skeletons of four ships within two hours’ sail of Kadiak, and how many small boats go ashore, never to be heard of, no man can tell. There are big ships lost, too, up and down this coast. Last year the natives below Kadiak brought in casks and boxes and all kinds of things bearing the name of the steamer Oregon. She was wrecked far to the south of Valdez, but the Japan Current carried her wreckage a thousand miles to the north and west, and threw it on the coast of Kadiak and the smaller islands west of there. It made the natives rich, they found so much in the way of supplies.”

“Are there any bears out there?” asked Jesse, wonderingly.

“Biggest in the world!” replied Uncle Dick. “You’d better keep away from them. We’re sailing now just south of the great Kenai Peninsula of Alaska. There’s bears over there, but mostly black ones. Plenty of moose and caribou in these mountains, and once in a while a grizzly, but the biggest grizzlies are the brown bears of Kadiak and the peninsula on beyond.”

Rob was silent for a time, but at last remarked: “From what I hear of this Kadiak country, I believe we’re going to like it. When’ll we get there?”

Uncle Dick smiled. “Oh, sometime within a week,” he answered. “Distances are long up here, and wind and tide have something to do with even a steamer’s speed.”
