76 EEPORT OF OFFICE OF EXPERIMENT STATIONS. 



during the last ten years, together with an account of the collection of 

 the bacteria, methods of isolation and study, and the classification and 

 naming of the species; discussion of the terms digestibility, avail- 

 ability, and fuel value; a discussion based upon the results of nutrition 

 investigations carried on under the auspices of this Department of the 

 proportion of nutrients supplied by different groups of food materials 

 in the average diet, the availability of different classes of nutrients in 

 food of mixed diet, heats of combustion of nutrients, fuel value, and 

 related topics; tables showing the available nutrients in a large num- 

 ber of animal and vegetable foods; detailed reports of dietary studies 

 with college students, a chemist's family, and a chemist; full data con- 

 cerning the history of four tuberculous cows and of calves fed upon their 

 milk, with a general summary of the results and practical deductions; 

 results for three years of experiments on corn, cowpeas, and soy beans, 

 to determine the effects of nitrogen in different quantities and combina- 

 tions; results of a rotation soil test planned to study the deficiencies of 

 soils and the fertilizer requirements of different crops; a brief account 

 of experiments begun in 1899 to test the relative value of stable 

 manure, a complete chemical fertilizer, and green manures, alone and 

 in combination with mineral fertilizers, as means of improving worn- 

 out soils; tabulated analyses of fodders and feeding stuffs; and a 

 monthly summary of meteorological observations during 1899. 



GENERAL OUTLOOK. 



Among the more important needs of agriculture in the State is a 

 clearer knowledge of the principles of nutrition of both plants and 

 animals. Intensive cultivation of crops and expert management of 

 herds are more and more indispensable to successful farming. It is 

 the effort of the station, therefore, to furnish information concerning 

 these matters. The field experiments are made for the special purpose 

 of studying the particular needs of different soils and crops and the 

 best methods of supplying them with fertilizers. Experiments are 

 also being made to learn the best method of restoring fertility to soils 

 that have long been under cultivation and are lacking in some of the 

 ingredients of plant food. In two lines of investigation — the nutrition 

 of animals and man, and dairy bacteriology — the Storrs Station has 

 done a relatively large amount of high grade work, the results of 

 which are favorably regarded both in the United States and in Europe.
