This long, languorous anthology fails to sustain the tension generated by the title poem by D.H. Lawrence. Rather, Carl Sanburg's rumbling ""Buffalo Dusk,"" May Swenson's fermentative ""How Everything Happens"" and some soaring Galway Kinnell represent the outer limits of energy while William Stafford's low-key, conversational rhythms (thirteen poems in all) set a pace that is sustained by short Eskimo songs, and some familiar Robert Frost, Walt Whitman, and Theodore Roethke. Similarly the limpid nature photographs strive for a mood of quiet contemplation. Definitely not an, adventurer's anthology, this nevertheless would make a pleasant, responsive companion for long summer afternoons at a lakeside cabin. . .or on a backyard patio. And though disappoiningly safe (it's hard to imagine why a collection on this theme would ignore, say, Gary Snyder, while including Myra Cohn Livingston) it offers a generous selection within a limited range.
