Photograph of the seeding of a mixture of native grass (100 acres) with one of the special drills constructed under the specifications of Soil Conservation District supervisors of the Central Washita River Valley of Oklahoma to plant small seeds of native and adapted grasses. A local iron works made the drills from second-hand grain drill frames, automobile transmissions, cotton planter boxes, discs and press wheels obtained by supervisors of the Grady Co., Stephens Co., South Caddo Co., and the Canadian-Walnut Soil and Conservation Districts [the last in McClain Co.]. drills were patterned after one constructed by the Woodward, Oklahoma Nursery. The cost of $300 each was shared by the districts. In 1945, 6 SCDs in the Central Washita River Valley seeded 5,161 acres with the aid of 2 small drills, lent by the Soil Conservation Service, compared with 11,000 acres seeded in all previous years. The districts are tackling the job of seeding 500,000 acres with the seven special drills. OK-9141.
