For full-time professional research workers, the continual study of the literature must be a way of life. Whatever problems they are working on are also being studied by many others. To fall out of current awareness can only lead to much waste of time and of research facilities. The following notes, however, are written not for the researcher but for those concerned with watershed management. Watershed managers certainly should keep abreast of progress elsewhere in forestry, soil conservation, hydrology, and the adaptations of technology illustrated in the previous chapter. The soil and water aspects of their problems are highly technical fields and do not yield readily to amateur solutions. Engineers, agronomists, foresters, and livestock and veterinary specialists need to be called on for advice and help. Having had that advice, those at the more remote stations will often enough have to put it into practice themselves.
