This bulletin gives the results of the investigations conducted in 1923 at the Northern Great Plains Field Station near Mandan, North Dakota in the semiarid Great Plains area. The work at this station includes experimental field testsin the growth of trees, shrubs, fruits, vegetables and field crops; cooperative shelter-belt investigations with farmers on the northern Great Plains; and a series of pasture experiments to study the management of native and cultivated grassland for grazing beef cattle.

The purpose of this report is to discuss briefly the experiments conducted at the Northern Great Plains Field Station, located in Morton County, North Dakota, two miles south of Mandan. No attempt is made to describe the experiments in detail, but rather to present the lines and scope of the work at the station and give a summary of results obtained from the various experiments. The projects are grouped and divided into three departments: arboriculture, horticulture, and agronomy. The cooperative grazing experiment is a coordinate part of the agronomic work. The work and results are reported separately by the men in charge of the respective departments.

This glossary, issued in 1924, and revised, provides terms used in fire control.
