Photograph of a UNIDENTIFED neighbor using Mr. Heber V. Burns' irrigation sprinkler on field of oats. A few buildings and grain elevator are visible in the background of photograph. The back of the photograph proclaims, "A neighbor uses Mr. Burns' irrigation sprinkler on field of oats. Irrigation has made Mr. Burns' 7-acre field of rye and hairy vetch highly productive.

Photograph of the inside cab view of soil coring machine from drivers seat. Tube cleaner in foreground is near the operator where 99% of fastened cores in tip can be jared loose by hand simply by setting tube in the cleaner and pushing downward on soil coring tube. Lower limit switch can be used with power by swinging around drive head with soil coring tube being lowered. Cover for drive mechanism. Hole in floor board to dispose of soil from the coring tube (hinged to jeep cab) and held open by 1/4 inch stove bolt which hinges to the right or left in double nut welded to jeep cab. Heater located so that heat is thrown back into cab. The base of the soil coring machine shown here is 1/4 inch slab steel and is too light for this application, the steel springs downward when pulling soils from heavy clays.

Photograph of an UNIDENTIFED man kneeling and inspecting wheat stubble. The photographer on the back of the photograph proclaims, "Stubble of 1952 wheat crop has been properly managed to prevent wind erosion and protect new wheat crop. Wheat residue was one-wayed once and land was disked just prior to planting new crop. Residue was kept in surface to hold soil against wind and to make best use of moisture. Present wheat needs rain to maintain growth."

Photograph of O. W. Rutledge and A. T. Elder, SCS Technician, examining lovegrass in an arid field. People shown in photo go as followed from left to right: 1. O. W. Rutledge, 2. A. T. Elder, SCS Technician. The back of the photograph proclaims, "Though retarded by long, severe dry spell, sand lovegrass planted in this 140-acre field is doing well. Planted in the spring of 1951, grass was grazed by 30 cows for three months (April, May, June) in 1952. Rutledge (left) tells SCS Technician A. T. Elder about his conservation plan to tie blown land down. Alfalfa and grass, he says, will be his progress, turning to wheat only every few years if weather and market are favorable."

Photograph of Harold C. Gould, SCS Technician, standing in a badly blown field in which entire wheat crop has been lost. The back of the photograph proclaims, "SCS Technician Harold C. Gould stands lonely and desolate in badly blown field in which entire wheat crop has been lost. Emergency tillage has been of no help in face of continuing winds because of clean condition of the land. Immediately across road is field of alfalfa that has not only prevented erosion but has furnished good grazing. IV RR 7X and 12X."

Photograph of Harold C. Gould, SCS Technician, looking over the wheat crop remains in this fifty-acre field ruined by wind erosion. A few buildings and grain elevator are visible in the far left and right background of photograph. The back of the photograph proclaims, "SCS Technician Harold C. Gould looks over remains of wheat in this 50-acre field. Crop ruined by wind erosion, field lacking enough residue to protect soil. III and IV RR 7x and 12x."

Photograph of Harold C. Gould looking at a field that has not enough crop residues present, which on this 50-acre field of wheat, completely blown away, resulting in the loss of the crop. A few buildings and grain elevator are visible in the far left and right background of photograph.

Photograph of the right side view of the Willis Jeep. Jeep w/soil coring machine attached. The tubes one 52" long for making 4 ft. tests in alfalfa land for high water table-three short tubes, one for collecting profile of shallow soil under native vegetation, one for collecting a deep soil profile under virgin conditions (sample to be carried into the cultivated field for comparison and evaluate soil losses) and a third short tube to be used in process of surveying. Cab should have ample window space for light, the inside being painted with aluminum paint for better light reflection. Comfortable seats, both front and back should be installed. The front seat here is a recovered bucket seat from a '36 Plymouth Panel. Muffler is moved outward and attached to body.

Photograph of an UNIDENTIFED man kneeling and inspecting wheat stubble. This photograph has no information written on the back, but is a duplicate or similar to 2019. 061. B5. 10132, which proclaims, "Wheat stubble of 1952 crop has been chiseled and properly one-wayed to protect this field against wind erosion. New wheat crop is doing well, but at the time picture was taken needed rain to sustain growth. This land is conditioned to take in and fully use any rain that falls. III RR 7."

Photograph of an UNIDENTIFED SCS Technician kneeling in a wheat field. The back of the photograph proclaims, "Properly managed residue of biennial sweet clover has provided effective protection against wind erosion. Wheat here is slightly taller and of darker green color than most wheat in locality, but when picture was taken rain was badly needed to sustain growth. SCS Technician notes effectiveness of clover residue. III RR 7-0 and 12."
