Some one had just called Dick's attention to the fact that Mlle. F——, the Landgrave's Parisian mistress, was standing within a few feet of the Landgrave's wife, when suddenly a terrible roar came from the menagerie, followed a moment later by a great four-footed, striped figure, which bounded into sight, then crouched and looked around with ferocious curiosity.

"The tiger has broken out!" an officer exclaimed, while everybody gazed at the animal as if struck dumb with sudden amazement and alarm.

A man rushed wildly out from the menagerie after the tiger,—he was the keeper, through whose carelessness the beast had escaped. At this sight the women began to scream and to run back to the carriages. In a moment or two, the Landgravine was left alone. She stood looking at the animal as if fascinated, or as if paralyzed with terror.

The keeper threw himself before the tiger. It felled him with a blow, drew the blood from his face with its claws, and began to tear his flesh with its teeth. The women shrieked with horror. The animal looked up, glided across the body of the man, and made swiftly towards the Landgravine.

A kind of shuddering moan went up from the whole field. Some officers dashed forward on their horses, as if to intervene between the Landgravine and the beast, though the great distance made the attempt a hopeless one.

As the tiger made its spring, a shot rang out. The beast gave a howl of pain, dropped sidewise, and lay still, at the Landgravine's feet, pierced through the brain.

The officers looked around amazed, and saw Dick Wetheral, afoot, lowering a smoking gun. He had slid from his horse at the tiger's first appearance, run to the nearest marksman, seized the loaded weapon, and fired as he had fired at many a running bear in Pennsylvania.

"Who fired?" cried the Landgrave, too deeply moved to say more,—for a prince does not wish his wife to die a violent death in his presence and the court's, however estranged he may be from her.

"I took the liberty, your highness," said Dick, handing back the gun to the guardsman, and approaching the Landgrave.

"You have saved the Landgravine's life," said his highness. "I lack words in which to express my gratitude. You shall hear from me."
