“That is funny, though I never thought of it before,” said Tom. “Don’t you suppose it’s currents or something?”

“Nope,” declared the second officer, “just chuck a couple of matches into a basin of water an’ leave ’em be, an’ you’ll see they’re boun’ to git side of each other.”

“Say, I have noticed that!” exclaimed Jim. “What’s the reason?”

“Give her up,” replied Mr. Kemp. “Mystery to me, but then there’s a heap of mysteries at sea.”

The boys had been greatly surprised too to find that they could see throughout the night, that there was no darkness, and that the sun set like a dull yellow ball, hung at the rim of the sea for a space, and almost before it disappeared, popped up again.

“Gosh, I never realized we were where the sun never sets,” cried Tom the first time he noticed this. “Somehow I can’t believe we’re way up here in the Arctic.”

The boys were vastly interested and fascinated in the Northern Lights, although compared with the midnight sun, they were faint and pale. Captain Edwards told them they would see the sight of their lives when winter came, and the Aurora blazed in all its glory.

But all these things grew tedious, and the boys longed for a whale to be seen, or for some exciting thing to happen. Then one day the shout so long expected rang from the masthead, and at the cry, “She blows!” all was excitement. Leaping into the shrouds, the two boys ran up the rigging. As Captain Edwards’ shout of, “Where away?” was answered by, “Three points off the lee bow!” the boys stared in that direction to see two little fountains of spray rise above the waves, and two immense rounded black objects break the water.

“Hurrah! there’re two of them,” cried Tom. “Oh, Captain Edwards, can’t we go after them?”
