“I don’t know,” said Rob, “but we’ll take the rope along and see how it works out.”

Not long after they were safely off in the big dory, which, under two pairs of oars and with the wind favorable, astern, made very good time down the long spit at the mouth of the creek. Beyond that point they were obliged to take to the open bay, quite out of touch of land, for a distance of a mile and a half. This brought them to the foot of a small, rocky island, out of which arose two or three sharp, column-like groups of rocks which, as Rob had said, were literally covered with nesting birds.

“We’ll have to get around behind,” said Rob; “nobody could climb up on this side, that’s sure.”

Scrambling over the loose rocks, left wet and slippery by the tide, they passed to the rear of these pillars, first having made fast the dory so that it could not be carried away. In the pools of sea-water they found many strange shells and several specimens of the squid, or cuttle-fish, upon which Skookie fell gleefully. He and his people are fond of this creature as an article of food; but its loathsome look turned the others against it, so that with reluctance he was forced to throw them away again.

At the back of the largest of these rock pinnacles they stood in hesitation for a moment, for the ascent seemed hard enough. At last, however, Rob found a sort of cleft or large crack, which seemed to lead up toward the top, and whose rough sides seemed to give foothold sufficient for a bold climber. “Here we go, fellows!” he said, and so started on up, hand over hand, the best he could. To their satisfaction, however, they found the going not so hard as it had looked from below. At the top, the sides of the cleft seemed to pinch together, so that in some places they were obliged to climb as a chimney-sweep does, their legs pressed across the open space; but as they were all out-of-door boys and well used to Alaska mountain work, they went ahead fearlessly and soon found themselves at the summit of the tower-like rock, whence they had a splendid view of the bay and the surrounding country. Startled by their presence, the sea-birds took wing in hundreds and thousands, soaring around them, flapping almost in their faces, and uttering wild, discordant cries. The boys fought these off as they began to explore the top of the rock.

“Mostly little gulls here,” said John, “and I never heard they were good to eat. I don’t like the look of these eggs, either. Looks as if we were too late for a real good egg season.”

“Well,” said Rob, “anyhow, we have had a good climb and a good look over the country. Now, what I propose to do is to see what there is lower down on the face of the cliff. I’m sure there’s a lot of sea-parrots there, because I can see them flying in and out down below.”

“Let me go down, Rob,” said John. “I’m lighter than you are.”

“No,” said Jesse, “I think I ought to go down, because I am even lighter than you, John, and Rob is stronger than either of us.”
