But he has also indisputable claims to a high rank as a man of letters. Some of his written pictures of birds, so graceful, clearly defined, and brilliantly colored, are scarcely inferior to the productions of his pencil. His powers of general description are not less remarkable. The waters seem to dance to his words as to music, and the lights and shades of his landscapes show the practised hand of a master. The evanescent shades of manners, also, upon the extreme frontiers, where the footprints of civilization have hardly crushed the green leaves, have been sketched with graphic fidelity in his journals. No author has more individuality. The enthusiastic, trustful and loving spirit which breathes through his works distinguished the man. From the beginning he surrendered himself entirely to his favorite pursuit, and was intent to learn every thing from the prime teacher, Nature. His style as well as his knowledge was a fruit of his experiences. He had never written for the press until after the age at which most authors have established their reputation; and when he did write, his page glowed like the rich wild landscape in the spring, when Nature, then most beautiful, "bathes herself in her own dewy waters." We seem to hear his expressions of wondering admiration, as unknown mountains, valleys and lakes burst upon his view, as the deer at his approach leaped from his ambush into the deeper solitudes, as the startled bird with rushing wings darted from his feet into the sky; or his pious thanksgiving, as at the end of a weary day the song of the sparrow or the robin relieved his mind from the heavy melancholy that bore it down. When the celebrated Buffon had completed the ornithological portion of his great work on natural history, he announced with unhesitating assurance that he had "finished the history of the birds of the world." Twenty centuries had served for the discovery of only eight hundred species, but this number seemed immense, and the short-sighted naturalist declared that the list would admit of "no material augmentation" which embraced hardly a sixteenth of those now known to exist. To this astonishing advance of the science of ornithology, no one has contributed more than Audubon, by his magnificent painting and fascinating history. Mr. Audubon left unpublished a voluminous autobiography, which we hope will be published with as little delay as possible. FOOTNOTES: [I] Wilson's Miscellanies, vol. ii. p. 118.
