Nursery Practice for Trees and Shrubs Suitable for Planting on the Prairie-plains
註釋This publication attempts to bring together the accumulated experience of the Forest Service in the field of nursery practice for deciduous trees and shrubs, especially for the prairie-plains region, including all phases of propagation, from the collection of the seed to the shipment of the trees out of the nursery. This information is hoped to be of wide-spread interest to nurserymen, foresters, and game conservationists.
