ng him to follow.

The stairs were uncarpeted, and had little feet-worn hollows in the
middle of them. The banisters were rickety, and had been notched by the
knives of reckless tenants. The first and second floors were occupied by
different families (so Marcus inferred from the distinct set of baby
cries issuing from each), and the halls were dirty, and flavored with a
decided odor of washing day. But on the third story he saw a clean,
white floor, and drew breaths of pure air from an open rear window, and
heard no noise save the dull sound of filing.

The little girl paused a second at a door bearing the inscription,
"Private," asked the visitor to please wait, and opened the door just
wide enough to admit her body, and entered, nearly closing it behind
her. In the one glance which Marcus then obtained of the interior of the
room, he saw the pale mechanic hastily rise from a jumble of cog wheels
before him, and put up a screen to shelter his work from observation,
after which he stepped forward, or rather sprang, to meet his child.

Mr. Wilkeson heard a few words of hurried conversation between the
father and daughter, and then the door was thrown wide open, and the

"and I thank you for saving me from the annoying visits of that
impertinent fellow. I beg, sir, that you will give me your address, and
assure you that the sum shall positively be repaid to you next week."

"Never mind the repayment," said Marcus, kindly. "The sum was a trifle
for me."

The mechanic's eyes flashed with new fire, and his lower lip curved
with pride, as he answered:

"But I shall insist on returning it, sir. We are temporarily poor, sir;
but we are not beggars yet, I trust that, some day, we shall be in a
position to confer benefits, instead of receiving them."

Marcus knew that the man was turning over in his mind the troublesome
question of "MOTIVE," with which so many people like to make themselves
unhappy; and he therefore said:

"I took the liberty of assisting you, si
