beasts. Let it be said that a tiger or a lion is loose, and it causes greater fear, even, than when it is stated that an elephant is on a rampage. An elephant seems a big, but good-natured, creature; though often they turn ugly. But a lion or a tiger is always feared when loose.

But the chances are not one in a hundred that a circus lion or a tiger, getting out of its cage, would attack any one. The creature is so surprised at getting loose, and so frightened at the hue and cry at once raised, that all it wants to do is to slink off and hide, and the only harm it might do would be to some one who tried to stop it from running away.

Joe Strong, Jim Tracy, and the other circus executives and employees knew this as soon as they heard the cry: "A tiger is loose." Who raised the cry and which of the several tigers in the Sampson show was out of its cage, neither Joe nor any of those in the big tent near him knew. But they realized the emergency, and knew what to do.

"Keep your seats! Don't rush!" cried Joe, as he released Helen's hand and hurried to the front of the platform. "There is no danger! The animal men will catch the tiger, if one is really loose. Stay where you are! Keep your seats! Don't rush!"

It is the panic and rush that circus men are afraid of—the pushing and "milling" of the crowd and the trampling under foot of helpless women and children.

There was some commotion near the junction of the animal tent and that in which the main performance took place. What it was, Joe did not concern himself about just then. He felt it to be his task to prevent a panic. And to this he lent himself, aided by Helen, Jim Tracy, and others who realized the danger.

And while this is going on and while the expert animal men are preparing to get back into its cage the tiger which, it was learned afterward, had got out through an imperfectly fastened door, time will be taken to tell new readers something about Joe Strong and the series of books in which he is the central character.

Joe Strong seemed destined for a circus life and for entertaining audiences with sleight-of-hand and other mystery matters. His father, Alexander Strong, known professionally as Professor Morretti, was a stage magician of talents, and Joe's mother, who was born in England, had been a rider of trick horses.

His parents died when Joe was young. He did not have a very happy boyhood, and one day he ran away from the man with whom he was living and joined a traveling magician, who called himself Professor Rosello. With him Joe, who had a natural aptitude for the business, learned to become a sleight-of-hand performer.

In the first book of the series, entitled "Joe Strong, the Boy Wizard; Or, the Mysteries of Magic Exposed," is told how Joe got on in life after his first start. Joe was not only a stage magician, but he had inherited strength, skill and daring, and he liked nothing better than climbing to great heights or walking in lofty and dizzy places where the footing was perilous. So it was perhaps natural that he should join the Sampson Brothers' Show. And in the second book is related, under the title, "Joe Strong on the Trapeze; Or, the Daring Feats of a Young Circus Performer," what happened to our hero under canvas.

Joe loved the circus life, even though he made some enemies. But he had many friends. There was Helen Morton. Then there was Benny Turton, who did a "tank act," and was billed as a "human fish." Jim Tracy, the ringmaster, Bill Watson, the veteran clown, and his wife, the circus "mother," Tom Layton, the elephant man who taught the big creatures many tricks, were only a few of Joe's friends.

Among others might be mentioned Señor Bogardi, the lion tamer, Mrs. Talfo, the professional "fat lady," Señorita Tanzalo, the pretty snake charmer, and Tom Jefferson, the "strong man." Joe loved them all. The circus was like one big family, with, as might be expected, a "black sheep" here and there.

Joe became an expert on the trapeze, and, later, when Benny Turton was temporarily in a hospital, Joe "took on" the tank trick. In the third volume some of his under-water feats are related, while in the fourth book Joe's acts on a motor cycle on the high wire are dealt with.

With his "Wings of Steel," Joe caused a sensation, and after an absence from the circus for a time he joined it again, bringing this act to it.

Eventually Joe was made one of the circus owners, and now controlled a majority of the stock. He had also inherited considerable money from his mother's relatives in England, so that now the youth was financially well off for one who had started so humbly.

The book immediately preceding this one is called "Joe Strong and His Box of Mystery; Or, the Ten Thousand Dollar Prize Trick." In that volume is related how Joe constructed a trick box, out of which he made his way after it was locked and corded about with ropes. Helen Morton helped him in this trick, which was very successful.

The circus management offered a prize of ten thousand dollars to whomsoever could fathom how the trick was done. Bill Carfax, an enemy of Joe's and a former circus employee, tried to solve the problem but failed.

The box trick was a great attraction for the circus, and Joe was in higher favor than before.

He had been on the road with the show for some time when the events detailed in the first chapter of this book took place.

By dint of much shouting and urging the people to retain their seats and not rush into danger, Joe Strong and the others succeeded in calming the circus crowd. Meanwhile there was much suppressed excitement.

"Is the tiger caught? Is he back in his cage?" was asked on every side.

While Joe and his fellow showmen were calming the crowd, the animal men were having their own troubles. Burma, one of the largest of the tigers, had got loose, having taken advantage of the open door of his cage. He rushed out with a snarl of delight at his freedom. His jungle cry was echoed by the roar of a lion in the next cage, and this was followed by the cries and snarls of all the wild jungle beasts in the tent.

Fortunately the animal tent was deserted by all save the keepers, the audience having filed into the tent where the main show was going on.

"Head him off now! Head him off!" cried Tom Layton, the elephant man, as he saw the tiger dart out of its cage—a flash of yellow and black. "Head him off! Don't let him get in the main top!"

"That's right! Head him off!" cried Señor Bogardi, the lion tamer. "He won't hurt any one—he's too scared!"

This was true, but it was difficult to believe, and some of the people seated in the "main top," or big tent, who were nearest the animal tent, hearing the cries and learning what had occurred, spread the alarm.

Burma, the tiger, slunk around in behind the cages of the other animals. All about him were men with clubs and pointed goads, with whips and pistols. The circus men had had to cope with situations like this before. They surrounded the tiger, advancing on him in an ever-narrowing circle, and in a short time they drove him into an emergency cage which was pushed forward with the open door toward him. Burma had no choice but to enter, to get away from the cracking whips and the prodding goads. And, after all, he was glad to be barred in again.

So, without causing any harm except for badly frightening a number of people in the audience, the tiger was caged again, and the circus performance went on.

Joe Strong did his Box of Mystery trick. The usual announcement of a reward of ten thousand dollars to whomsoever could solve it was made, and there was great applause when Joe managed to get out of the big box without disturbing the six padlocks or the binding ropes.

"I'm glad Bill Carfax isn't here to make trouble, trying to show how much he knows about this trick," said Joe to the ringmaster, as he stepped off the stage at the conclusion of the trick.

"Yes, you put several spokes in Bill's wheels when you turned the laugh on him
