materials that have possible value in soil and water conservation work. This work is done at 18 plant materials centers strategically located in the principal plant-growth regions of the United States. Some are operated by the Soil Conservation Service, others cooperatively with land grant colleges. Potentially useful plant materials are evaluated in the field to determine their soil and climatic adaptation, growth and seed habits, and their potential conservation values. Plant performance is evaluated jointly with state experiment station personnel, farmers, ranchers and state and federal agencies that are engaged in similar work. Supplies of certified materials are increased by members of crop- improvement associations, soil conservation dis- trict cooperators and commercial nurserymen. The plant Materials Center that the New Mexico State Experiment Station and SCS operate is at Los Lunas, New Mexico and it serves New Mexico and Colorado. The Center develops new and improved varieties of grasses, shrubs, and so on, for conservation purposes. This isn't only for farms. We have two agreements in New Mexico with the game and fish department there and the department of highways to develop im- proved species for specific uses for those departments. Most of these, however, are devel- oped for on farm or ranch use. Examples of newly developed grains include Vaughn side-oatsgrama, Grenville switch grass, Llano Indian grass, Amur Intermediate wheatgrass, Largo tall wheat, Lovington Blue grama, pastura Little bluestem, Elida Sand bluestem, Luna pubescent wheatgrass, and Jose' tall wheatgrass. Virtually all of the new grasses that have been developed in Colorado for Colorado in the last ten or fifteen years have come from this source. Something I know you gentlemen would be particularly interested in, the relation of water, our work in snow surveys and water supply forecasts. The SCS makes and coordinates snow surveys in the West and in Alaska, and prepares I I
