He caught up a bundle of dried grass, and Jack took up several sticks, dry and tindery, ready to burst into flame as soon as a light was set to them. All three now crawled through the low, half-blocked doorway. As soon as they crept into the darkness, a strong, fetid, musty smell, mingled with a horrible scent of decay, made the air pungent and choking.

"Some beasts or other here," murmured Mr. Haydon calmly. "Let's see if they're dangerous."

He struck a match and applied it to the great bundle of dried grass which he had collected. The flame ran through it at once, and it flared up strongly. Jack thrust a stick into the blaze, and they now had ample light to see around them.

They found themselves in a large, low room, whose floor was littered with bones and the remains of animals dragged there for food. They darted glances on every side to discover what kind of beast it was whose lair they had entered. But for a moment they saw nothing. There was a movement in a bed of dried reeds in one corner, and presently they saw two pretty little creatures, having the appearance of big cats, bound out and begin to yowl plaintively. At sight of them the native woman gave a shrill scream of terror.

"Tiger cubs!" snapped Mr. Haydon.

He glanced quickly around the place, but there was no sign of any other living creature there save the two cubs, which now began to frisk about the light.

"Lucky for us Mrs. Stripes isn't at home," said Jack, "or it would have been a case of out of the frying-pan into the fire."

"It would," agreed his father. "But it isn't long since she was here," he added. "Here's a fresh kill."

He pointed to a small buck lying almost at their feet. The blood was still wet on the graceful creature's coat, and it was untorn save for the rents made by the huge claws which had brought it down and dragged it to the tiger's lair.

"If this is the only place available," said Mr. Haydon quietly, "we shall have to creep out again. It isn't healthy to ask a tigress to go halves in her den when she's rearing a family."
