teach school."

Farnam laughed. "On the whole, it might be better to leave the
cartridges out. If somebody did break in, all you need do would be to
pretend you were asleep. Everybody in the neighborhood knows where my
office is and an intelligent burglar begins at the safe. There's no
money in mine now."

After a little good-humored banter, Agatha took the pistol and Farnam
went to his office at the other end of the house. Next day he started
for Montreal, and at night Mrs. Farnam made Agatha come with her while
she examined the fastenings of the doors and windows. The house was low
and the roof of the veranda in front reached nearly to the second
floor. Nothing disturbing happened, and on the next night Agatha sat up
after Mrs. Farnam had gone to bed, reading the letters Strange had
written her from the North.

There were not many, and some were marked by a careless style that
obscured the meaning. This puzzled Agatha, who remembered that her
father had generally talked with lucid clearness. Still they helped her
to picture the life he had led in the wilds, and she read them often,
trying to follow on a map his wanderings in search of the lode. They
told her more about the country than the books she read, and she had

learn would be of use when she came to carry out her plans.

When she tied up the letters and looked at the clock it was later than

few moments, musing. The house was quiet and she imagined Mrs. Farnam
was asleep; but it was snowing, for she heard the flakes beat upon the
window. Looking round the comfortable room, she thought of the men who
braved the rigors of winter in the frozen wilds. Thirlwell, for example,
was bearing such cold as was never felt in South Ontario.

She started, for there was a noise overhead, as if a door had been
gently opened, but next moment pulled herself together. Mabel had not
gone to sleep as she had thought, and picking up an electric torch, she
put out the lamp. When she was half way up the stairs she heard somebody
moving about, but it was not like Mabel's step. The movements seemed
cautious, and there was something awkward about them. Agatha, who wore
felt-soled slippers, stopped and listened, while her heart beat fast.
She heard nothing now, but felt alarmed, and wondered what she ought to
do. A call would probably bring an answe
