on, but he would answer no more questions.

About two weeks after that he set off fishing to the Horr Brook again,
and again returned with two big trout. Nobody else who fished there had
caught anything weighing more than half a pound; and in the lake, at
that time, there was nothing except pickerel. But all that Addison would
say was that he did not have any trouble in catching such trout.

The mystery of those trout puzzled us deeply. Not only Halstead and I,
but Thomas Edwards, Edgar Wilbur and the Murch boys all did our best to
find out where and how Addison fished, but quite without success.

Cold weather was now at hand and the fishing over; Addison astonished
us, however, by bringing home two noble trout for Thanksgiving day.

[Illustration: THOSE BIG TROUT.]

The next spring, about May 1st, he went off fishing, unobserved, and
brought home two more big trout. After that if he so much as took down
his fish-pole, the rumor of it went round, and more than one boy made
ready to follow him. For we were all persuaded that he had discovered
some wonderful new brook or trout preserve.

Not even the girls could endure the grin of superior skill which Addison
wore when he came home with those big trout. Theodora and Ellen also
began to watch him; and the two girls, with Catherine Edwards, hatched a
scheme for tracking him. Thomas had a little half-bred cocker spaniel
puppy, called Tyro, which had a great notion of running after members of
the family by scent. If Thomas had gone out, and Kate wished to discover
his whereabouts, she would show him one of Thomas's shoes and say, "Go
find him!" Tyro would go coursing around till he took Thomas's track,
then race away till he came upon him.

The girls saved up one of Addison's socks, and on a lowery day in June,
when they made pretty sure that he had stolen off fishing, Ellen ran
over for Kate and Tyro. Thomas was with them when they came back, and
Halstead and I joined in the hunt. The sock was brought out for Tyro to
scent; then away he ran till he struck Addison's trail, and dashed out
through the west field and down into the valley of the Horr Brook.

All six of us followed in great glee, but kept as quiet as possible. It
proved a long, hot chase; for when Tyro had gone along the brook as far
as the lake woods, he suddenly tacked and ran on an almost straight
course through the woods and across the bushy pasture-lands, stopping
only now and then for us to catch up.
