"And then, Professor," said Jack, "I would like to know what _parallax_ means."

"There," said Gus, "is another big word of Jack's--pallylacks, knickknacks, gimcracks, slapjacks!"

"Hush, you goose."

"I think," said the Professor, "I can answer May's and Jack's questions both at once, as they are very closely connected. Suppose that at night, when you look down the street, you see two gas lamps, one much farther off than the other. Then if you go across the street, the nearer lamp will seem to move in the opposite way from what you did. Thus, in the diagram, when you are at A, the nearer lamp is on the right of the other, and when you go over to B and look at it, it is on the left. This change in direction is called _parallax_. Now we can imagine the nearer one of the lights to be the moon, and that an observatory, or tower with a telescope in it, is located at A, from which the direction of the moon is carefully noted at six o'clock in the morning. Then by six in the evening the earth, spinning round on its axis, will have carried the observatory about 8000 miles away from A, and placed it at, say, B. If the moon's direction be again noted, it is very easy to calculate her distance by a branch of mathematics called trigonometry, which Jack, I have no doubt, has already studied."

A FOUR-FOOTED MESSENGER

Just after the raising of the siege of Fort Stanwix, in the Mohawk Valley, the neighborhood continued to be infested with prowling bands of Indians.

Captain Gregg and a companion were out shooting one day, and were just preparing to return to the fort, when two shots were fired in quick succession, and Gregg saw his comrade fall, while he himself felt a wound in his side which so weakened him that he speedily fell.

Two Indians at the same time sprang out of the bushes, and rushed toward him. Gregg saw that his only hope was to feign death, and succeeded in lying perfectly still while the Indians tore off his scalp.

As soon as they had gone, he endeavored to reach his companion, but had no sooner got to his feet than he fell again. A second effort succeeded no better, but the third time he managed to reach the spot where his comrade lay, only to find him lifeless. He rested his head upon the b.l.o.o.d.y body, and the position afforded him some relief.

But the comfort of this position was destroyed by a small dog, which had accompanied him on his expedition, manifesting his sympathy by whining, yelping, and leaping around his master. He endeavored to force him away, but his efforts were in vain until he exclaimed, "If you wish so much to help me, go and call some one to my relief."

To his surprise, the animal immediately bounded off at his utmost speed.

He made his way to where three men were fishing, a mile from the scene of the tragedy, and as he came up to them began to whine and cry, and endeavored, by bounding into the woods and returning again and again, to induce them to follow him.

These actions of the dog convinced the men that there was some unusual cause, and they resolved to follow him.

They proceeded for some distance, but finding nothing, and darkness setting in, they became alarmed, and started to return. The dog now became almost frantic, and catching hold of their coats with his teeth, strove to force them to follow him.

The men were astonished at this pertinacity, and finally concluded to go with him a little further, and presently came to where Gregg was lying, still alive. They buried his companion, and carried the captain to the fort. Strange as it may seem, the wounds of Gregg, severe as they were, healed in time, and he recovered his perfect health.

WILL'S BELGIAN NIGHT.

BY MATTHEW WHITE, JUN.

"Just like so many sheep!"

This was Will Brooks's exclamation, as he waited, with his elder brother Charlie, at the Northern Railroad station, in Paris. And truth to tell, the pa.s.sengers were driven about and distributed somewhat after the manner of flocks, for, having purchased their tickets, they were obliged to pa.s.s along a corridor, opening into which were medium-sized waiting-rooms, separated from one another only by low part.i.tions, and labelled, so to speak, as first, second, and third cla.s.s. Here they were compelled to wait until five or ten minutes before the train was to leave, during which interval everybody endeavored to obtain the place nearest the door, so as to be sure of a choice of seats in the cars.

Will and his brother had succeeded in getting pretty near the k.n.o.b, where they were nearly suffocated with bad air, and much bruised by the satchels and umbrellas of their fellow-travellers.

"Now, Will, be ready," said Charlie, as a man was seen to approach with a key in his hand.

"All right; America to the front!" returned his patriotic brother; and at the same moment the doors were flung open, and in his nasal French tones the guard sang out, "Pour Liege, Aix-la-Chapelle, et Cologne!"

With a rush as of the sudden breaking away of a long pent-up mountain stream, the crowds surged forth from their "pens," and ran frantically up and down the long platform in search of the carriages for which they were respectively booked. The first-cla.s.s compartment which Will and his brother had selected was speedily occupied by the six others required to fill it, their companions consisting of a gentleman and his wife, an old lady and a little boy, and two young men, evidently all French.

Everybody had got nicely settled, the luggage was arranged in the racks overhead, and the train was just about to start, when a lady mounted to the doorway, with a little girl in one hand, and a bag, basket, and umbrella in the other. With a great volume of French she endeavored to thrust the child into the compartment, but was forced to desist from the attempt in deference to the remonstrances of the majority of those who already occupied it.

"C'est complet! c'est complet!" was the cry, and in the midst of the confusion the guard approached to close the doors preparatory to starting. To him the distressed lady appealed in behalf of her offspring, for whom, she declared, there was no room in any of the carriages, and further stated that she herself was obliged to remain with her youngest, who was at present in charge of her next to the youngest in another car. The guard was finally obliged to settle matters by delaying the train, and adding thereto another carriage.

The conversation incidental to the foregoing episode had been interpreted to Will by his brother, whose French had been polished up considerably during his three weeks' stay in Paris. He and Will were over for an autumn tour in Europe, and having "done" the British Isles and the capital of France, they were now on their way to Germany.

Will had enjoyed his trip thus far immensely, even though he knew no modern language but his American English, and he now looked forward to seeing the wonders of the father-land with all the bright antic.i.p.ations of fourteen.

"What's that for, I wonder?" he suddenly exclaimed, catching sight of a small triangular piece of looking-gla.s.s set in the upholstery at the back of the front seat of the compartment. "Read what it says underneath, Charlie;" which the latter accordingly did, reporting that it was a device for calling the guard in cases of emergency, the way of doing so being to break the gla.s.s and pull a cord which would be discovered in the recess thus exposed, which cord communicated with the engine. But if the gla.s.s be broken, the notice went on to state, without sufficient cause, a heavy fine would be imposed on the offender.

"But suppose I couldn't read French, as indeed I can't," surmised Will, "and were in here alone--that is, alone in company with a crazy man who was about to murder me--how could I ever imagine that by smashing that bit of gla.s.s I might stop the train, and so be rescued? Besides--"

"Nonsense!" interrupted his brother. "Don't you see the directions are repeated both in English and German underneath?" and Will looked and saw, and immediately turned his attention out of the window, leaving Charlie to peruse his French newspaper in peace.

There was, however, not much of interest to observe in the somewhat barren-looking country through which the railroad ran; and voting France (Paris excepted) a very slow place indeed, Will buried himself for the rest of the afternoon in a boy's book of travels. Nevertheless, the journey proved a very tedious one, and after stopping for dinner at six, the two brothers endeavored to bridge over the remaining hours with sleep.

"Verviers!" shouted out by the guard, was the sound that caused them both to awake with a start. The train had stopped, and all the pa.s.sengers were preparing to "descend," as the French have it.

"Now, Will," said Charlie, sleepily, trying to read his guide-book by the light of the flickering lamp in the roof of the compartment, "this is the Belgian custom-house; but all trunks registered through to Cologne, as ours is, they allow to pa.s.s unopened; but it seems that everybody is required to get out and offer their satchels to the officers for examination; but, as we've only one between us, there's no use in our both rousing up, so you just take this, and follow the crowd."

"All right," responded Will, now thoroughly wide-awake; "then I can say I've been in Belgium;" and s.n.a.t.c.hing the small hand-bag from the rack, he hurried off, leaving his brother to continue his nap.

"Wonder which room it is?" surmised Will, for the platform was deserted, and there were four waiting-apartments opening out on it. It did not take him long, however, to discover the proper one for him to enter, and he was soon among the jostling crowd that surrounded the low counter, behind which were the customs officials, who sometimes opened a bag and glanced over the contents, and then hastily marked on it with a piece of chalk, but oftener simply chalked it without examining anything whatever, which latter harmless operation was all to which Will's effects were subjected.

Rejoiced at getting through so easily, he turned to hasten out to the cars again, but the door by which he had entered was now closed, and guarded by a gendarme. From the gestures the latter made when he attempted to pa.s.s him, Will understood that he was to go out by another exit into an adjoining waiting-room, where he found most of the other pa.s.sengers a.s.sembled in the true flock-of-sheep style; but while he was wondering where he might be driven to next, he saw through the window the train, containing his brother, his ticket, and his power of speech, whirl suddenly away into the darkness, and disappear.

"Hallo here! let me out!" cried Will, rushing up to the officer stationed at the door. "I'm going to Cologne on those cars, don't you understand?"

But the man evidently did not understand, for he shook his head in a most stupid fashion, at the same time feeling for his sword, as though afraid "le jeune Americain" were going to brush past him with the energy characteristic of the nation.

Seeing that it was now too late for him to catch the already vanished train, even if he should succeed in gaining the tracks, Will gave up the attempt, and resigned himself to his fate.

"But why are not the other pa.s.sengers in as great a state of anxiety as I am?" he thought, as he looked around at his sleepy fellow-travellers, who had disposed themselves about the room in various att.i.tudes of weariness and patience. "Perhaps, though, they're not going to Cologne; very likely they're all bound for some place in Belgium here, on another road. And now what's to become of me, a green American, with no French at my tongue's end but 'oui' and 'parlez-vous,' not a sign of a ticket, and with but six francs in my purse? Oh, Charlie, why did you send me out with this bag?" and Will paced nervously up and down the waiting-room, trying to think of a way out of his predicament. Suddenly a happy idea struck him.
