nd it was growing very
dark. But the boy again repeated his request, and Malcolm gave his
consent.

Halbert had been accustomed to the mountains from his earliest boyhood,
and Shag set out with his young master, not seeming to care for wind,
snow, or storm.

They reached the village safely. Halbert saw the doctor, received some
medicine for his mother, and then started on his return home with a
cheerful heart.

Shag trotted along before him to see that all was right. Suddenly,
however, in one of the most dangerous parts of the rocky path, he
stopped and began snuffing and smelling about.

"Go on, Shag," said Halbert.

Shag would not stir.

"Shag, go on, sir," repeated the boy. "We are nearly at the top of the
glen. Look through the dark, and you can see the candle shining through
our window."

Shag disobeyed for the first time in his life, and Halbert advanced

He had proceeded but a few steps when he fell over a precipice, the

But alas! Halbert was not there. Shag was alone. The old dog entered
the door, and began to whine in a piteous manner.

"O Malcolm, Malcolm, my brave son has perished in the snow!" exclaimed
the mother.

Malcolm stood wondering. His heart beat rapidly. A fear that the worst
had happened almost overcame him. At that moment he saw a small package
around the dog's neck.

Seizing it in his hands, he exclaimed, "No, wife; look! Our boy lives!
Here is the medicine, tied with his handkerchief; he has fallen into one
of the deep ravines, but he is safe.

"I will go out, and Shag shall go with me. He will conduct me safely to
the rescue of my child."

In an instant Shag was again on hi
