An examination of the books recommended for children's study and delight will reveal a large number of the most graceful, inspiriting products of human thought, which are nature poems, nature hymns, odes to skylark, the dandelion, the mountain daisy, communings with the myriad moods and forms of the natural world. Such books as "Nature Pictures by American Poets," "Golden Treasury of Songs and Lyrics," "Poetry of the Seasons," the "Open Sesame" books, and others, show an infinite variety of poetic inspiration from nature. Adding to these Burroughs's "Birds and Bees," "Wake Robin," "Squirrels and other Fur-bearers"; Thoreau's "Succession of Forest Trees"; Higginson's "Outdoor Papers"; Keyser's "News from the Birds," "In Bird Land," and "Birddom"; Torrey's "Footpath Way," and "Birds in the Bush"; Long's "Wilderness Ways," and "Ways of Wood Folk"; the "Plant World" of Vincent, the "Natural History" of Selborne, and others of like quality,--and we have an abundance of the most friendly and enticing invitations to nature study. These materials are suited, by proper arrangement, to all the grades from the fourth up. Under good teachers such books can do no other than awaken and encourage the happiest kind of observation and sympathy for nature. It is the kind of appreciation of birds and trees, insects and clouds, which at once trains to close and discriminating perception, and to the cultivation of æsthetic sense in color, form, and sound. The love of nature cannot be better instilled than by following these poets. While the study of literature as it images nature cannot take the place of pure science, it is the most powerful ally that the scientist can call in. The poets can do as much to idealize science study, to wake the dull eye, and quicken the languid interest in nature, as scientists themselves. Away, then, with this presumed antagonism between literature and science! Neither is complete without the other. Neither can stand on its own feet. But together, in mutual support, they cannot be tripped up. The facts, the laws, the utilities, adaptations, and wonders in nature are not so marvellous but the poet's eye will pierce beneath and above them, will give them a deeper interpretation, and clothe them in a garment of beauty and praise. There is nothing beautiful or grand or praiseworthy that the poet's eye will not detect it, and the poet's art reveal it in living and lasting forms. Let the scientist delve and the poet sing. The messages between them should be only those of cheer. It is in this myriad-voiced world of fields and brooks, of mountain, lake, and river, of storm and cloud and of the changing seasons, that poets find the images, suggestions, and analogies which interpret and illustrate the spiritual life of man. The more rigid study of science in laboratory and class-room is necessary to the student, but it would be a narrow and pedantic teacher who would not welcome the poetic temper and enthusiasm in nature study.
