the foul current, stopping often to rest, talking affectionately to
Jasper, and trying, in a childish way, to console him.

At last his work was nearly completed, but the gruff sounds of
distress from the frightened mule had ceased. Ralph held his lamp up
out of the current, so that the light would fall through the little
opening, and looked in.

Jasper lay there on his side, his head resting on the coal bottom, a
long, convulsive respiration at intervals the only movement of his
body. He was unconscious, and dying. The boy drew back with tears in
his eyes and with sorrow at his heart. The beast had been his friend
and companion, not only in his daily toil, but here also, in the
loneliness and peril of the poisoned mine. For the time being, he
forgot his own misfortunes in his sympathy for Jasper. He put his face
once more to the opening.

"Good-by, Jasper!" he said, "good-by, old fellow! I couldn't help it,
you know, an'--an' it won't hurt you any more--good-by!"

He drew back his head, put the few remaining stones in place, chinked
the crevices with dirt and culm, and then, trembling and faint,
he fell to the floor of the old mine, and lay there, panting and

But it was not of himself he was thinking; it was of poor old Jasper,
dying on the other side of the black wall, deserted, barred out,

Finally it occurred to him that he should go to some other place in
the mine. The poisonous gases must still be entering through the
crevices of his imperfectly built and rudely plastered wall, and it
would be wise for him to get farther away. His oil had nearly burned
out again, and he refilled his lamp from the can. Then he arose and
went down the chamber.

It was a very long chamber. When he reached the foot of it he found
the entrances into the heading walled up, and he turned and went along
the air-way for a little distance, and then sat down to rest.

For the first time he noticed that he had cut his hands badly, on the
sharp pieces of coal he had been handling, and he felt that there was
a bruise on his side, doubtless made when he fell through the opening.

Hitherto he had not had a clear idea as to the course he should pursue
when he should have obtained entrance into the old mine. His principal
object had been to get into pure air.

Now, however, he began to consider the matter of his escape. It was
obvious that two methods were open to him. He could eith
