OF PENNSYLVANIA. 55 



The character of the full Course of Studies is sufficiently 

 indicated by what has just been given in relation to them. 

 They are arranged to combine the study of Scientific prin- 

 ciples with their practical application. 



The Student studies each of the several sciences purely 

 as a scientific study, and then his attention is devoted to 

 their practical application to agriculture and the industrial 

 arts. For example, he studies the science of Chemistry 

 in the class-room and laboratory, until he is able to analyze 

 all the substances that will be presented to him, as ores, 

 rocks and minerals for the miner; slags, fuel, metals and 

 alloys for the furnace operator; residual products for the 

 manufacturing chemist ; poisonous substances and abnormal 

 secretions for the physician; adulterated articles for the 

 consumer; and soils, marls, limestones, phosphates, guanoes, 

 ashes, and all other articles used or consumed in agricul- 

 ture for the farmer. 



His attention is then devoted to the agricultural bear- 

 ings of the science. The manures found in the market 

 are put in his hands. He learns by analyzing them, to 

 distinguish between the good and bad, and his labors are 

 so superintended that his results* will be valuable to the 

 farmers of the country when published. A large number 

 of the analyses of manures found in the market, have 

 already been published. A course of experiments upon 

 the farm, with different kinds of manures for different 

 plants, is also being carried out, from year to year, upon a 

 large scale; while smaller plots, with suitable manures, are 

 allotted to students, that they may repeat for themselves 

 the experiments of the larger plot on a small scale, and 

 thus familiarize themselves with the experimental pro- 

 cesses by which, with the use of a few simple manures, 

 they may ascertain what soils need to bring them to the 

 highest degree of perfection a desideratum once sought 

 by soil analyses, but never attained by them.
