"Don't have to keep count," he replied. "See that indicator?" he continued, pointing to a dial in the ceiling which had not been noticed before. "That reads May 3, 1898, now, don't it? Well, it's fixed to keep always tellin' the right date. It counts the whirls we make an' keeps tabs on every day we go backward. Any time all ye hev to do is to read that thing an' it'll tell ye jest what day 'tis."

"Then what do you want to calculate how often to whirl round?" asked Phoebe, in disgusted tones.

"Well, ye see I want to plan out how long it'll take," Droop replied. "I want to go slow so as to avoid side weight--but I don't want to go too slow."

"I see," said Phoebe. "Well, then, how many times a minute did the future man take you when you whirled back five weeks?"

"'Bout two times a minute."

"That's one hundred and twenty times every hour. Did you feel much side weight then?"

"Scarcely any."

"Well, let's see. Divide eight thousand and thirty-five whirls by one hundred and twenty, an' you get sixty-seven hours. So that, ef we go at that rate it'll be two days and nineteen hours 'fore we get back to 1876."

"Don't talk about days," Droop objected. "It's sixty-seven hours by the clock--but it's twenty-two years less than no time in days, ye know."

"Sixty-seven hours," said Phoebe. "Well, that ain't so bad, is it? Why not go round twice a minute?"

"We can't air our beds fer three days, Phoebe," said Rebecca.

"But if we go much faster, we'll all be sick with this side weight trouble that Mr. Droop tells about."

"I vote fer twice a minute," said Droop. And so twice a minute was adopted.

"Air ye goin' to start to-night, Mr. Droop?" asked Rebecca.

"Well, no," he replied. "I think it's best to wait till to-morrow. Ye see, the power that runs the Panchronicon is got out o' the sunlight that falls on it. Of course, we're not all run out o' power by a good lot, but we've used considerable, an' I think it's a little mite safer to lie still fer a few hours here an' take in power from the sun. Ye see, it'll shine steady on us all night, an' we'll store up enough power to be sure o' reachin' 1876 in one clip."

"Well," said Rebecca, "ef thet's the plan, I'm goin' to bed right now.

It's after eight o'clock, an' I didn't get to sleep las' night till goodness knows when. Good-night! Hedn't you better go, too, Phoebe?"

"I guess I will," said Phoebe, turning to Copernicus. "Good-night, Mr.

Droop."

"Good-night, Cousin Phoebe--good-night, Cousin Rebecca. I'll go to bed myself, I b'lieve."

The two doors were closed and Droop proceeded to draw the steel shutters in order to produce artificially the gloom not vouchsafed by a too-persistent sun.

In half an hour all were asleep within the now motionless conveyance.

CHAPTER V

DROOP'S THEORY IN PRACTICE

All were up betimes when the faithful clock announced that it ought to be morning. As for the sun, as though resenting the liberties about to be taken by these adventurers with its normal functions, it refused to set, and was found by the three travellers at the same alt.i.tude as the night before.

Promptly after breakfast Droop proceeded to don a suit of furs which he drew from a cupboard within the engine-room.

"Ye'd better hev suthin' hot ready when I come in again," he said. "I 'xpect I'll be nigh froze to death."

He drew on a huge cap of bear's fur which extended from his crown to his shoulders. There was a small hole in front which exposed only his nose and eyes.

"My, but you do look just like a pictur of Kris Kringle!" laughed Phoebe. "Don't he, Rebecca?"

Rebecca came to the kitchen door wiping a dish with slow circular movements of her towel.

"I don't guess you'll freeze very much with all that on," she remarked.

"Thet shows you don't know what seventy or eighty below zero means,"

said a m.u.f.fled voice from within the fur cap. "You'll hev suthin' hot, won't ye?" Droop continued, looking appealingly at Phoebe.

"The'll be a pot o' good hot tea," she said. "That'll warm you all right."

Droop thought of something more stimulating and fragrant, but said nothing as he returned to the cupboard. Here he drew forth an apparently endless piece of stout rope. This he wound in a thick coil and hung over his head.

"Now, then," he said, "when I get down you shet the door at the top of the stairs tight, coz jest's soon's I open the outside door, thet hall's goin' to freeze up solid."

"All right!" said Phoebe. "I'll see to it."

Droop descended the stairs with a heavy tread, and as he reached the foot Phoebe closed the upper door, which she now noticed was provided with weather-strips.

Then the two women stood at the windows on the right-hand side of the vessel and watched Droop as he walked toward the pole. He raised the huge iron ring, snapping over it a special coupling hook fixed to the end of the rope.

Then he backed toward the vessel, unrolling the coil of rope as he moved away from the pole. Evidently they were within the forty-foot limit from the pole, for Droop had some rope to spare when he at length reached under the machine to attach the end to a ring which the sisters could not see.

He emerged from beneath the bulging side of the vessel swinging his arms and blowing a mighty volume of steam, which turned to snow as it left him. As he made directly for the entrance again, Phoebe ran to the kitchen.

"Poor man, he'll be perished!" she exclaimed.

As Droop entered the room, bringing with him a bitter atmosphere, Phoebe appeared with a large cup of hot tea.

"Here, Mr. Droop," she said, "drink this quick!"

Copernicus pulled off his cap and sat down to drink his tea without a word. When he had finished it, he pulled back his chair with a sigh.

"Whillikins! But 'twas cold!" he exclaimed. "Seems mos' like heaven to get into a nice warm room like this!"

"An' did ye get every thin' done right?" Rebecca asked.

"I guess I did," he said, emphatically. "I don't want to take no two bites out o' that kind o' cherry."

He rose and proceeded to remove his fur coverings.

"Goin' to start right now?" said Phoebe.
