The story of Timour the Tartar learning a lesson of perseverance under adversity from the spider is well known. Not less interesting is the anecdote of Audubon, the American ornithologist, as related by himself: “An accident,” he says, “which happened to two hundred of my original drawings, nearly put a stop to my researches in ornithology. I shall relate it, merely to show how far enthusiasm—for by no other name can I call my perseverance—may enable the preserver of nature to surmount the most disheartening difficulties. I left the village of Henderson, in Kentucky, situated on the banks of the Ohio, where I resided for several years, to proceed to Philadelphia on business. I looked to my drawings before my departure, placed them carefully in a wooden box, and gave them in charge of a relative, with injunctions to see that no injury should happen to them. My absence was of several months; and when I returned, after having enjoyed the pleasures of home for a few days, I inquired after my box, and what I was pleased to call my treasure. The box was produced and opened; but reader, feel for me—a pair of Norway rats had taken possession of the whole, and reared a young family among the gnawed bits of paper, which, but a month previous, represented nearly a thousand inhabitants of air! The burning beat which instantly rushed through my brain was too great to be endured without affecting my whole nervous system. I slept for several nights, and the days passed like days of oblivion—until the animal powers being recalled into action through the strength of my constitution, I took up my gun, my notebook, and my pencils, and went forth to the woods as gaily as if nothing had happened. I felt pleased that I might now make better drawings than before; and, ere a period not exceeding three years had elapsed, my portfolio was again filled.”
