"'Tis logical to contend," said he, "that the question of the girth of the tree will enter importantly into our devices. For example, if a tree be so huge that your hands may not meet on the far side of it, a successful ascension will be impossible. On the other hand, a very slim tree is like to bend beneath your weight, and even precipitate you heavily to the ground, which disaster might retard events for an indefinite period."
"Science your science, then," said I. "And tell me what manner of tree best suits the purpose of a true lover."
"A tree," said the Doctor, "is a large vegetable arising with one woody stem to a considerable height. As to the appearance and quality of a tree, there are many diversifications, and this fact in itself constitutes the chief reason for this vegetable being of such great use to the human family. Ships are made of nought but trees, and if it were not for ships we would know but little of the great world of which these English islands form less than a half. Asia itself is slightly larger than all Scotland, and if it were not for the ships we would be like to delude ourselves with the idea that we and our neighbours formed the major part of the world."
With such wise harangues the Doctor entertained my impatience until it was time for me to climb a tree. And when this time came I went at my work without discussion or delay.
"There," said I resolutely, "I will climb this one if it kills me."
I seized the tree; I climbed. I will not say there was no groaning and puffing, but any how I at last found myself astride of a branch and looking over the wall into the Earl of Westport's garden.
But I might have made myself less labour and care by having somebody paint me a large landscape of this garden and surveyed it at my leisure. There I was high in a tree, dangling my legs, and staring at smooth lawns, ornamental copses, and brilliant flower-beds without even so much as a dog to enliven the scene. "O'Ruddy," said I to myself after a long time, "you've hung yourself here in mid-air like a bacon to a rafter, and I'll not say much to you now. But if you ever reach the ground without breaking your neck, I'll have a word with you, for my feelings are sorely stirred."
I do not know how long I sat in the tree engaged in my bitter meditation. But finally I heard a great scudding of feet near the foot of the tree, and I then saw the little Doctor bolting down the road like a madman, his hat gone, his hair flying, while his two coat-tails stuck out behind him straight as boards.
My excitement and interest in my ally's flight was so great that I near fell from my perch. It was incomprehensible that my little friend could dust the road at such speed. He seemed only to touch the ground from time to time. In a moment or two he was literally gone, like an arrow shot from the bow.
But upon casting my bewildered glance downward I found myself staring squarely into the mouth of a blunderbuss. The mouth of this blunderbuss, I may say, was of about the width of a fair-sized water-pitcher; in colour it was bright and steely. Its appearance attracted me to such an extent that I lost all idea of the man behind the gun. But presently I heard a grim, slow voice say,—
