It was one o'clock when the explorer called a halt. On every hand was the field of ice and snow. But far ahead could be seen something which looked like a big iceberg. The sun was still under a cloud.

"I think we have gone far enough," said Barwell Dawson. "We'll camp here, and wait until we can take an observation."

No time was lost in gathering cakes of ice and building a fair-sized _igloo_. The boys worked with renewed interest. Had they really and truly reached the North Pole at last?

"At the most we cannot be over a mile or two away from it," said the explorer.

All were glad to rest, yet sleep was almost out of the question. The one thought of each member of the party was, "Are we at the Pole, or how much further have we to go?"

Early in the morning it was cloudy, but about ten o'clock the sun came out faintly.

"Unless it comes out full, I cannot take an accurate observation," said the professor.

All waited impatiently and watched the sky. When it was a quarter to twelve the clouds rolled away to the eastward, and the sun burst forth with dazzling brightness.

"Now is our chance!" cried Chet.

All a.s.sisted the professor in his preparations to take the all-important observation. The old scientist's chronometer was compared with that of Barwell Dawson.

"A difference of but three seconds," said the former. "We will split the difference when I take the observation," and this was done.

The s.e.xtant was raised, and the old scientist looked through it with great care. His artificial horizon had been arranged but a short distance away.

"Time!" roared Barwell Dawson, and the professor set the thumbscrew of his instrument. Then, through the magnifying gla.s.s, he read the figures and set to work with pen and pencil, making his computations, with his Nautical Almanac before him. All awaited breathlessly what he might have to say. Suddenly the aged man threw down the paper and pencil and threw his arms into the air.

"We are at the 90th degree of north lat.i.tude!" he cried. "We have reached the North Pole!"

"Hurrah!" yelled Andy and Chet, simultaneously, and Barwell Dawson joined in the cheer.

"You are certain of that?" asked the explorer. "We must make no mistake."

"Read the observation for yourself," answered the old scientist.

"It is true," said Barwell Dawson, when he had verified the figures. "We are really and truly at the North Pole. Now, then, to raise the flag!"

The others understood. All through the bitter journey they had carried an American flag and a fair-sized flagpole. Once the flag had become torn but they had mended it with care.

In a twinkling the pole was brought forth, and planted in the ice and snow. Then the flag was raised, and it floated proudly in the breeze.

"Three cheers for Old Glory!" cried Barwell Dawson, and the cheers were given with a will.

"Three cheers for Barwell Dawson!" cried Andy, and he and Chet and the old scientist gave them, roundly. Then there followed a cheer for Professor Jeffer.

"And now a cheer for the first boys at the North Pole!" cried Barwell Dawson, and he and Professor Jeffer raised their voices as loudly as they could. The boys could scarcely contain themselves, and both danced a jig, and then Andy turned half a dozen handsprings, just by way of working off his superfluous spirits.

It was wonderful what a difference reaching the Pole made in them. All the hardships of the past weeks were forgotten, and even the men acted like schoolboys out for a holiday. They walked around the vicinity of the _igloo_, and sang and whistled, and for once completely forgot their hunger. Then, during the course of the afternoon, Professor Jeffer took more observations and a number of photographs.

The next day the sun continued to shine brightly, and promptly at noon another observation was made. This gave the same result as before, so all were a.s.sured that they were really at the 90th degree of north lat.i.tude.

"We must be at the North Pole," said Andy. "For see, while we call one part of the twenty-four hours day and the other night, the sun goes right around us and never seems to rise or sink."

"Yes, that is something of a test," answered Professor Jeffer. "But it is not as infallible as that made by the s.e.xtant. The earth is more or less flat here, and that makes a difference."

To make "dead certain" that they had covered the North Pole, the entire party journeyed five miles further ahead, and also an equal distance to the right and left. At one point they saw traces of another exploring party, but the snow and ice had covered up the records left behind.

"And now to get back," said Barwell Dawson, at the close of the third day spent at and around the Pole. "We have no time to spare, if we want to get out of this land of desolation before winter sets in again."

"I am ready," answered Professor Jeffer. "I have taken all the observations and photographs I wish, and have collected a valuable amount of data."

"You can't get back any too quick for me," said Chet, dryly.

"There is no use in disguising the fact that our provisions are very low," continued Barwell Dawson, gravely. "We have very little left for the dogs."

"What will you do with them?" asked Chet.

"One is a little lame. If the worst comes to the worst, we'll kill him and feed him to the others."

They left the _igloo_ standing, and on the top placed a metallic box containing a brief record of their trip. Then they took down the flag and placed it on the sledge.

They started on the return at seven in the morning. The weather was not so cold as it had been, and going seemed to be better, so they covered the twenty-two miles to their old camp without much difficulty. Here they had to repair the sledge again, and also had to kill off the lame dog. This made a feast for the others, and gave them some food that was much needed.

"I could almost eat dog meat myself," said Chet.

"It may come to that," answered Andy. "I guess it is a heap better than nothing, when a chap is starving."

They found the new ice on the lead much thicker than it had been, and so crossed with ease. But now came on a heavy fall of snow, and all traces of their former trail were wiped out.

"We'll have to steer by eyesight and the compa.s.s," announced Barwell Dawson.

The boys were so hungry that they kept an eye open continually for game.

But not so much as a bird showed itself. It was truly the land of ice and snow, and nothing else.

On the fifth day, the case containing alcohol sprung a leak, and all of the precious stuff was lost in the snow.

"We'll have to eat our meals cold after this," said Barwell Dawson. "Too bad, but it can't be helped."

"I don't care how cold they are, if only we could get enough," grumbled Chet. An almost empty stomach did not tend to put him in good humor.

Another day pa.s.sed, and again it snowed. The flakes were so thick they could not see around them, and so had to halt and go into camp. Their provisions were now so low that only half rations were dealt out.

"We can't stand this," cried Chet. "I've got to have something to eat."

"Oh, Chet, don't grumble," answered Andy. "We are as bad off as you are."

"To-morrow, if we find it necessary, we'll kill off one of the dogs for food," said Barwell Dawson. "That will leave us a team of four, and we ought to be able to get back to where we left the others with those. The sledge has next to nothing on it now."

The morning dawned, dull and cheerless. They had a few mouthfuls of food, and then hitched up the dogs once more. n.o.body felt like talking, and they started on their long journey in silence.

Painfully they covered fifteen miles. Each was footsore and weary to the last degree, and not able to go another step. They sat down on a ridge of ice, and looked at each other.
