They went up to the house along the bank of the clear stream. On the side porch, vine-covered to the eaves, sat an old woman rocking in a low chair and another figure in what seemed at a distance, to be a child's wagon of wickerwork, but with no tongue and a high back to it.
“Here's Gran'pop!” cried a shrill voice and the little wagon moved swiftly to the edge of the steps. Nan almost screamed in fear as it pitched downward. But the wheels did not bump over the four steps leading to the ground, for a wide plank had been laid slantingly at that side, and over this the wheels ran smoothly, if rapidly.
“You have a care there, Corson!” shrilled the old lady after the cripple. “Some day you'll break your blessed neck.”
Nan thought he was a little boy, until they met. Then she was surprised to see a young man's head set upon a shriveled child's body! Corson Vanderwiller had a broad brow, a head of beautiful, brown, wavy hair, and a fine mustache. He was probably all of twenty-five years old.
But Nan soon learned that the poor cripple was not grown in mind, more than in body, to that age. His voice was childish, and his speech and manner, too. He was bashful with Nan at first; then chattered like a six-year-old child to her when she had once gained his confidence.
He wheeled himself about in the little express wagon very well indeed, old Toby having rigged brakes with which he moved the wagon and steered it. His arms and hands were quite strong, and when he wished to get back on to the piazza, he seized a rope his grandfather had hung there, and dragged himself, wagon and all, up the inclined plane, or gangplank, as it might be called.
He showed Nan all his treasures, and they included some very childish toys, a number of them showing the mechanical skill of his grandfather's blunt fingers. But among them, too, were treasures from the swamp and woods that were both very wonderful and very beautiful.
Old Toby had made Corson a neatly fitted cabinet in which were specimens of preserved butterflies and moths, most of them of the gay and common varieties; but some, Nan was almost sure, were rare and valuable. There was one moth in particular, with spread wings, on the upper side of the thorax of which was traced in white the semblance of a human skull. Nan was almost sure that this must be the famous death's-head moth she had read about in school; but she was not confident enough to say anything to old Toby Vanderwiller. A few specimens of this rare insect have been found in the swamps of America, although it was originally supposed to be an Old World moth.
Nan did say, however, to Toby that perhaps some of these specimens might be bought by collectors. The pressed flowers were pretty but not particularly valuable. In the museum at the Tillbury High School there was a much finer collection from the Indiana swamps.
“Sho!” said Toby, slowly; “I wouldn't wanter sell the boy's pretties. I brung most on 'em home to him; but he mounted 'em himself.”
