smoke began to fill the passage. This change in the color of the smoke
warned the brave young boy that the flames were approaching. At this
moment, too, he heard a crash, a fall, and a sudden roaring up of the
fire, somewhere near at hand. Again in frantic agony he renewed his
assault upon the door. This time it was suddenly torn open by the boys
within.

And horrors of horrors! what a scene met his appalled gaze! One portion
of the floor of the room had fallen in, and the flames were rushing up
through the aperture from the gulf of fire beneath. The two boys,
standing at the open door, were spell-bound in a sort of panic.

"What is it?" asked one of them, as if uncertain whether this were
reality or nightmare.

"It is fire! Don't you see! Quick! Seize each of you a blanket! Wrap
yourselves up and follow me! Stoop near the floor when you want to

then!"

It is marvelous how quickly we can understand and execute when we are in

in his wet woollen clothes, and the boys in their blankets, dashed for
the last flight of stairs--keeping their eyes shut to save their sight,
and their lips closed to save their lungs--and so reached the ground
floor.

Here a wall of flame barred their exit through the front door; but they
turned and made their escape through the back one.

They were in the open air! Scorched, singed, blackened, choked,
breathless, but safe!

Here they paused a moment to recover breath, and then Ishmael said:

"We must run around to the front and let them know that we are out!" The
two boys that he had saved obeyed him as though he had been t
