The poetry of August Derleth, a versatile and voluminous poet from Sac Prairie, often reminds of improvisation upon the piano…. ["Rind of Earth"] is thoroughly American in grain. The poem about the young men in "Yesterday, Tomorrow, Always," the train in "Transcontinental," "River Going By," the American myths in "Raftsman, Lumberjack," the poem about the radio, such things as these not only have flowing theme-molded rhythm, but close observation and the pulse of life. Sometimes I think Mr. Derleth may be too musical for his own good, but, in a day when so few poets seem to give the actual movement of a poem any attention, he restores an element that was badly needed.
