But those letters were H.T.
and there was therefore no connection between these three sets of letters.
Tom knew well enough the habit of the Temple Camp scouts of carving their initials everywhere.

The rough bench where they waited for the mail wagon to come along was covered with initials.

And among them Tom recalled a certain sprightly tenderfoot, Theodore Howell by name, who had been at camp early that same season.

Doubtless this artistic triumph on the bulging back of Llewellyn was the handiwork of that same tenderfoot.
And likely enough, too, those letters up in the woods were the initials of Harry Thorne, still at camp.

Tom would ask Harry about that.
