Professor Bull Frog discovered a strange tree, and called his comrades.

They inspected it with profound interest.

It was very tall and straight, and wholly devoid of bark, limbs, or foliage.
By triangulation Lord Longlegs determined its altitude; Herr Spider measured its circumference at the base and computed the circumference at its top by a mathematical demonstration based upon the warrant furnished by the uniform degree of its taper upward.

It was considered a very extraordinary find; and since it was a tree of a hitherto unknown species, Professor Woodlouse gave it a name of a learned sound, being none other than that of Professor Bull Frog translated into the ancient Mastodon language, for it had always been the custom with discoverers to perpetuate their names and honor themselves by this sort of connection with their discoveries.
Now Professor Field-Mouse having placed his sensitive ear to the tree, detected a rich, harmonious sound issuing from it.

This surprising thing was tested and enjoyed by each scholar in turn, and great was the gladness and astonishment of all.
