The arrangements in regard to admittance, fees, diplomas, holidays, 

 &c., and in regard to hospitanten are similar to those in the Agri- 

 cultural and Forest College at Hohenheim, though varying in 

 several particulars. 



In illustration of the advantages of combining a School of Forestry 

 with other educational arrangements, I may state that tliere are 

 only two professors of Forest Science in the Polythechnicum at Carls- 

 ruhe. Most of the classes not taught by them attended by students 

 of forestry are classes taught in some of the other schools or faculties 

 of the institution. The exceptions are that the Professor of Economics 

 has a special meeting with the students of forestry one a hour week 

 during the summer session, and the Professor of Kural Economy in the 

 University of Heidelberg has a meeting with them for two hours once 

 a week both summer and winter. 



A similar advantage is gained at Giesen by connecting the School 

 of Forestry with the University. Where it is desirable to minimize 

 as much as possible the staff of teachers, much may be effected by 

 substituting for several separate professorships one of Economic 

 Botany and Forest Economy. 



In connection with economic botany might be communicated 

 information in regard to the differences subsisting between vegetables 

 and animals and minerals ; the structure and physiology of plants ; 

 the structural development of thallogens, acrogens, endogens, and 

 exogens ; the morphology and classifications of plants, with an expo- 

 sition of the doctrine of evolution ; the chemistry of vegetation and 

 the relation to this of soils, manures, heat, and moisture, with the 

 climatal effects of vegetation on the heat, humidity, and chemical 

 constituents of the atmosphere ; the chemical constitution of vege- 

 table products, and the preparation of these for use in the arts and 

 manufactures and as luxuries, medicines, or food ; the natural dis- 

 tribution of plants and the means of acclimatization, of culture, and 

 of stimulating the production of economic products in roots, stems, 

 bark, leaves, flowers, fruits, or seeds. 



In connection with forest economy, instruction might be given as 

 I have suggested in another case in the structure and physiology of 

 trees and shrubs ; in the geographical distribution of forests ; in
