Their ever-readiness for a rough-and-tumble, the fact that neither had ever been known to dodge trouble—although neither had ever sought it, and that where one was involved in danger there was sure to be found the other also—had gained for them among the rough men of the lumber camp the nickname of "The Boy Allies," a name which had followed them to their city home.

It was by this name that the boys were most endearingly known to their companions; and there was more than one small boy who owed his escape from older tormentors to the "Boy Allies'" idea of what was right and wrong, and to the power of their arms.

Both lads were keenly interested in history, so, in spite of the manner in which they tried to reassure Mrs. Paine and set her mind at rest, there is no cause for wonder in the fact that both were more concerned in the movement of troops and warships than in the efforts the other powers were making to prevent a general European war.

Staunch admirers of Napoleon and the French people, and, with a long line of descendants among the English, the sympathies of both were naturally with the Allies. As Chester had said to Hal, when first rumors of the impending conflagration were heard:

"It's too bad we cannot take a hand in the fighting. The war will be the greatest of all time, and both sides will need every man they can get capable of bearing arms."

"You bet it's too bad," Hal had replied; "but we're still in Europe, and you never can tell what will happen. We may have to play a part in the affair whether we want to or not," and here the conversation had ended, although such thoughts were still in the minds of both boys when they accompanied Mrs. Paine to their apartment to pack up, preparatory to their departure in the morning.

The packing completed, the lads announced their intention of walking out and learning the latest war news.

"We won't be gone long, mother," said Hal.

"Very well, son," Mrs. Paine replied; "but, whatever you do, don't get into any trouble. However, I do not suppose there is any danger to be feared—yet."

For more than an hour the lads wandered about the streets, reading the war bulletins in front of the various newspaper offices, and listening to crowds of men discussing the latest reports, which became more grave every minute.

As the boys started on their return to their hotel, they heard a shout down a side street, followed immediately by more yells and cries; and then a voice rang out in English:

"Help! Police!"

Breaking into a quick run, Hal and Chester soon were upon the scene of confusion.

With their backs to a wall, two young men were attempting to beat back with their fists a crowd of a dozen assailants, who beset them from three directions.

As the two boys rounded the corner, the cry for help again went up.

"Come on, Chester!" shouted Hal. "We can't let that gang of hoodlums beat up anyone who speaks the English language."

"Lead on!" cried Chester. "I am right with you!"

They were upon the crowd as he spoke, and Hal's right fist shot out with stinging force, and the nearest assailant, struck on the side of the neck, fell to the ground with a groan.

"Good work, Hal!" shouted Chester, at the same time wading into the crowd of young ruffians, for such the attackers proved to be, and striking out right and left.

Howls of anger and imprecations greeted the attack from this unexpected source, and for a moment the ruffians fell back. In the time that it took the crowd to return to the struggle, the boys forced their way to the side of the victims of the attack, and the four, with their backs to the wall, took a breathing spell.

"You didn't arrive a moment too soon," said one of the young men, with a smile. "I had begun to think we were due for a trimming."

"There are four of us here," returned Hal, "and we ought to be good for that crowd; but, instead of standing here, when they attack again, let's make a break and fight our way through. There will be more of them along in a minute, and it will be that much harder for us."

"Good!" returned the second stranger in French. "Here they come!"

"Are you ready?" asked Hal.

"All ready," came the reply from the other three.

"All right, then. Now!"

At the word the four rushed desperately into the throng, which was pressing in on them from three sides. Taken by surprise, the enemy gave way for a moment; then closed in again.

Blows fell thick and fast for the space of a couple of minutes. Then, suddenly, Chester fell to the ground.

Turning, Hal fought his way to the other side of Chester's prostrate body. Then, bending down, he lifted his chum to his feet.

"Hurt much?" he asked.

"No," replied Chester, shaking his head like an enraged bull. "Let me get at them again!"

He rushed in among his assailants with even greater desperation than before, and two young hoodlums fell before his blows.

In the meantime the strangers were giving a good account of themselves, and the enemy were falling before their smashing fists.

Hal ducked a blow from the closest of his assailants, and, stepping in close, struck him with all his power under the chin. The youth fell to the ground.

As he did so the ruffian nearest him, with a hiss of rage, drew a knife, with which he made a wicked slash at Hal. Hal did not see the movement, being closely pressed elsewhere, but Chester, with a sudden cry, leaped forward and seized the hand holding the knife, just as the weapon would have been buried in Hal's back.

"You would, would you, you coward!" he cried, and struck the young German in the face with all the strength of his right arm. The latter toppled over like a log.

All this time the crowd of assailants continued to grow. Attracted by the sounds of the scuffle, reinforcements arrived from all directions, and it is hard to tell what would have happened had not the sudden blast of a whistle interrupted the proceedings.

"The police!" yelled someone in the crowd. "Run!"

In less time than it takes to tell it, Hal, Chester, and the two other young men were alone, while racing toward them, down the street, were several figures in uniform.

"Run!" cried the young Frenchman. "If they catch us we will all go to jail, and there is no telling when we'll get out. Run!"

The four took to their heels, and, dodging around corner after corner, were soon safe from pursuit.

"Well, I guess we are safe now," said the Englishman, when they stopped at last. Then, turning to Hal:

"I don't know how to thank you and your friend. If you had not arrived when you did, I fear it would have fared badly with us."

"No thanks are due," replied Hal. "It's a poor American who would refuse to help anyone in trouble. Shake hands and call it square!"

The Englishman smiled.

"As modest as you are bold, eh? Well, all right," and he extended his hand, which Hal and Chester grasped in turn.

But the Frenchman was not to be put off so easily. He insisted on embracing both of the boys, much to their embarrassment.

"I'm Lieutenant Harry Anderson, of the Tenth Dragoons, His Majesty's service," explained the Englishman, and then, turning to his friend: "This is Captain Raoul Derevaux, Tenth Regiment, French Rifle Corps. We were strolling along the street when attacked by the
