igued to succeeding scores of visitors.

About this time, it was observed of Captain Tonkins that he began to
show signs of fatigue, rocking heavily in his seat with every
oscillation of the sleigh, and talking thick like a jaded man. These
phenomena seeming to require some explanation, the Captain stated that
he had been up late the past three nights, and could keep himself awake
only by taking occasional draughts of Quigg's brandy. The Captain then
proceeded to indulge in random recollections of his political career,
and withering denunciations of one Larry Mulcahy, his successful rival
for the office of School Inspector, whom the Captain did not hesitate to
brand as a jailbird.

When the party returned to the block where the Overtop theory was to be
tested, Mr. Quigg's services were found invaluable. He had not only been
the principal grocer in the vicinity for five years, but he had served
on Ward Committees for the relief of the poor at other people's expense,
and had participated largely in those admirable institutions for the
promotion of matrimony known as Sociables. Therefore, Quigg knew about
everybody on the block worth knowing. There were a few persons in that
old house near the corner, who sent in for herrings, cheap butter, and
pounds of flour, and whom, of course, he did not know. There was a queer
old Dutchman in that square, old-fashioned house in the middle of the
block, whom neither he nor anybody else knew.

They went through half of the south side of the block, and found only
plain and commonplace people. Overtop and Maltboy began to be weary. The
former was gradually discovering that his theory was a bore. The latter
wondered whether Quigg knew the tall girl, concerning the identity of
the front part of whose residence Maltboy was at fault, although he knew
every brick of the rear.

"In this 'ere house," said Quigg, "I shall be treated rudely, because
they owe me fifty dollars for groceries. It's a curious fact, but I have
noticed that debtors always act kind o' cold to creditors, as if it was
the creditors that owed the money."

Mr. Quigg spoke with an important air, as if he had made an original
discovery in human nature.

CHAPTER VI.

SOMETHING HIDDEN.

While this exploring party were going through the block, Mr. Marcus
Wilkeson dressed himself with more than usual care, preparatory to a
call upon the unknown old gentleman over the way, who that very morning
had appeared at his win
