The butterfly, safe under leaf and flower, Has found a roof, knowing how true thou art; The bumble-bee, within the last half-hour, Has ceased to hug the honey to its heart; While in the barnyard, under shed and cart, Brood-hens have housed.—But I, who scorned thy power, Barometer of the birds,—like August there,— Beneath a beech, dripping from foot to hair, Like some drenched truant, cower. This, however, is airy imagination as compared with the naturalist fidelity of much of Mr. Cawein’s work in _Weeds by the Wall_, _A Voice on the Wind_, and in _Kentucky Poems_,—to which Mr. Edmund Gosse contributes a sympathetic introduction,—books chiefly upon nature, occasionally reverting to the mythological or more imaginative phase of the subject, but in the main set to reveal the fact, with its aura of beauty; for it is never the purely elemental side of a nature-manifestation that presents itself to Mr. Cawein, but always the fact haloed by its poetic penumbra. Indeed, the limitation of his earlier work lay in the excess of fancy over reflection and art; but his growth has been away from the romantic toward the realistic and individual, and upon this side its best assurance for the future is given. Mr. Cawein has yet far too facile a pen not to be betrayed by it into excesses both of production and fancy. He writes too much to keep to the standard set in his best work of the past two or three years, and lacks still to a great degree the self-scrutiny which would reject much that he includes; but granting all this, it must be apparent to any reader of his work that he is not a singer making verse for diversion, but one to whom poetry is the very breath of his spirit, one who lives by this air, and can by no other; and while it is one thing to be driven through vision-haunted days by beauty’s urgence and unrest, and another to body forth the vision in the calm; one thing to have had the mystery whispered by a thousand wordless voices, and another to communicate it in terms of revealing truth—it is notable in Mr. Cawein’s verse that he is teaching his hand to obey him more surely each year, and is producing work that quickens one’s perception of the world without, and adds to his sum of beauty. It is serious work, work with purpose, and while its fancy still runs at times to the fantastic, it shows so marked a growth in technique and spirit from year to year that one may well let to-morrow take care of to-morrow with a poet who brings to his art the ideal which inspires Mr. Cawein.
