Some attempts at saving the run-off have proved partially successful, but they are rather expensive 74. Further studies in these directions are amply warranted, especially with respect to the treatment to which seeds of certain valuable forage plants should be subjected in order to secure sure and rapid germination and growth. Some results of experimentation.--Carefully conducted experiments on the Jornada Range Reserve in south central New Mexico, by the Forest Service, in cooperation with an experienced stockman, have yielded some very accurate figures that are practically conclusive proof of the advantages of an improved type of range management possible only on fenced land. This reserve contains approximately 200,000 acres of mountain and plain grass-land, mostly of forage type No. 2, the semi-desert grass land (see p. 14), and carries from 3,000 to 5,000 head of stock, depending upon the annual climatic variations.
