COURSES FOR STUDENTS OF GRAZING 363 



Following the general course in chemistry, which should 

 include qualitative and quantitative analytical and organic work, 

 a special course should be given in the determination of the 

 chemical constituents of feeds and forage crops. While it should 

 not be the aim to make of the student a full-fledged chemist, a 

 course covering, let us say, one credit unit through a semester 

 would suffice to familiarize him with the methods employed in 

 making analyses of feeds and the preparation of forage samples 

 for analysis. 



The course in animal husbandry — genetics and veterinary 

 science — should aim to offer special work in the application of 

 principles to improve livestock production. In animal hus- 

 bandry, for instance, consideration should be given to the rela- 

 tive merits of the different breeds of livestock as related to cli- 

 mate, the temperament of different breeds of stock as affecting 

 their relative adaptability on the range, maintenance-ration re- 

 quirements of animals, and the suitability of different kinds of 

 concentrate feeds in the different localities, etc. The apphed 

 work in genetics should consider especially the question of 

 breeding as related to the creation of improved strains of Uve- 

 stock, such, for instance, as cross-breeding in the development 

 of the mutton type of sheep, the wool type, and the combined 

 mutton and wool type. Likewise the study of veterinary 

 science should include a consideration of the life history and con- 

 trol of diseases common to livestock on the range. 



Obviously a thoroughgoing course in civil engineering, includ- 

 ing mechanical drawing, is of paramount importance to the range 

 technician. 



The meteorological work should consider the vegetative types 

 and the chief crop-producing areas of the United States, followed 

 by a study of the normal temperatures and of the precipitation 

 of these areas, taking into account the barriers and the general 

 trend of the high and low pressure phenomena and their relation 

 to precipitation. Consideration should be given to the study 

 of weather forecasts and to climatic cycles, so far as they influ- 

 ence forage and livestock production, and to the recording and 

 assembhng of climatic data, especially with reference to deter-
