Photograph of a row of 60-year old cottonwood trees planted by John Rhus. The present state of the trees without understory is causinga more detrimental wind action than if no trees were present by funneling of the wind along the ground surface. Underplanting is needed. John Logan, Farm Forester, is the man in the picture. OK-79, 489.

Photograph of a concentration of field and farmstead windbreaks in the northern portion of the Greer County Soil Conservation District, Oklahoma. This is an unusually good observational area as windbreaks of all types are present. Note the lack of continuity in the single row plantings--a constant characteristic of such belts in limited rainfall zones. OK-79, 501.

Photograph of the community patterns of windbreaks in the northeastern part of the Greer County Soil Conservation District, Oklahoma. Plantings date from 1935 and are being added to each year. This area was formerly treeless, and even along the stream courses, but now—from a distance—it has almost the aspect of a wooded country. Variations in continuity and vigor of the belts is chiefly due to differences in degree of care and protection afforded the plantings—the soils for the most part being well suited for the storage of moisture. OK-79, 497.

Photograph of windbreaks, showing a row of 60 year old cottonwood trees planted by John Rhus. The present state of the trees without understory is causing a more detrimental wind action than if no trees were present by funneling of the wind along the ground surfaces. Underplanting is needed [i.e., to fill around, under, or among, for example, trees, with lower-growing plants]. John Logan, Farm Forester is the man in the picture. OK-79, 489.

Photograph of of a row of 60-year old cottonwood trees planted by John Rhus. The present state of the trees without understory is causing a more detrimental wind action than if no trees were present through the funneling of the wind along the ground surface. OK-10, 276.

Photograph of windbreaks protecting valuable farm land east of the Lake Creek Store in the northeastern part of the Greer County Soil Conservation District. The heavily foliaged windbreak in the lower right-hand corner of the photograph is a partnership planting on the Craig and Wilde farm boundary It was planted in 1935 by the Forest Service. The dark-colored fields are alfalfa—a crop that responds particularly well in seed production when protected from the wind. OK-79, 499.

Photograph of the Dempsey Brothers Farm on extremely sandy soil in the southwestern corner of the Greer County Soil Conservation District, northeast of Blair, Oklahoma. The first plantings were made in 1935 and the pattern gradually enlarged during the ensuing years. Crop land, orchards, vineyards and the farm buildings all lie within the same protecting scheme. The Dempsey Brothers claim great benefits in soil stabilization and increased crop and orchard yields. Their fruit has been saved many times. OK-79, 500.
