註釋The successful artificial seeding of deteriorated range lands offers much promise for improving the economic security of western range states. It has been demonstrated that artificial seeding is the most rapid means of increasing the quantity and improving the quality of forage for livestock as well as for stabilizing the soils against erosion hence, it contributes directly to the stability of the agricultural industry and to the general welfare of the states involved. Agricultural pursuits have always been, and appear destined to be, the fundamental basis for a permanent society in the West. The present study was undertaken to learn more fully the influence of some environmental factors upon the survival of grass seedlings, and the characteristics of these seedlings in resisting the vicissitudes of weather. Such knowledge is necessary in order to help protect plants against adverse conditions by planting at such a time and in such a way as to enable the young plants to escape some of the extremes.
