They were both instructors of youth, but under circumstances widely different. The one was a preceptor of youth in the sequestered nooks of Pennsylvania; the other became the dignified lecturer from beneath a canopy spread over him by regal munificence. The one taught the elements of Education--the other enlarged on the lore of Science. As an instructor, Linnæus was the more successful. He resembled in some measure the Greek philosophers who taught in the suburbs of Athens, and he made Hammarby a kind of Swedish Lyceum. He possessed a remarkable talent for waking into action the latent enthusiasm of his pupils. What custom could have been more inspiring than the one he introduced at Upsal, of dividing his pupils into bands, and enjoining it on the leader of each to sound a horn when a plant should be discovered, never before seen by the fervid eye of science. This enthusiasm accounts for the fact, that his pupils subsequently explored so many countries, and investigated their floral kingdoms, whilst one of them accompanied Sir Joseph Banks round the world, and sounded his bugle among the islands of the Pacific. {76} They both enlarged the limits of Science. Before the time of the Swedish philosopher, Botanists had arisen in different countries; and from the earliest periods, studies based on the objects of nature must have drawn attention both for ornament and use. Lord Bacon, from the elevation which he occupied above the rest of his species, looked far into the wonders of Natural History; but Linnæus took entire possession of the green and flowery land, and led in the tribes of men to enjoy its fragrance and pluck its fruit. The poetical affections have from the infancy of time been associated with vernal buds and flowers. Poetry, when it assumes the form of language, is the melody which the mind makes when the imagination is excited by objects in the frame-work of nature, or by events susceptible of picturesque representation. In the floral games men were acting from ideal impulses, and they were doing the same through the ages of chivalry. They thus furnished materials out of which Tasso reared his immortal work. But it is one thing to look at objects as they sparkle through the medium of the imagination, and another to open on the same objects the eye of science. Many have celebrated the loves of the Shells who have not understood Conchology, and Darwin understood Plants scientifically without comprehending them poetically. But Linnæus possessed astonishing invention, and he easily detected the errors of ancient systems, and convinced mankind of the superiority of that system which bore the seal of his own imperishable mind. In like manner the Ornithologist did not strike out into ways entirely novel, but he extended paths on which men had hitherto gone for the acquisition of knowledge. He has greatly enlarged our views of the history and habits of the feathered race. From the mountain's height,
