The dairy and bacteriological laboratory of Professor Fleischmaun, 

 whose name is identitied with the development of dair}' science in all 

 its phases from its beginning until the present time, consists of two 

 rooms, one about 24 by 40 feet and the other 24 by 14 feet, with 

 accommodations for less than half a dozen students. The agricultural 

 chemical laboratory (Professor Tollens) consists of two rooms, one for 

 qualitative and quantitative analysis, with accommodations for 36 stu- 

 dents, and one for advanced or thesis work, for 10 students. The gen- 

 eral auditorium or lecture room of the agricultural institute has a seat- 

 ing capacity of about 36, and is never crowded — less than ever later 

 in the semester, owing to 

 the German system of non- 

 compulsory attendance. 



For purposes of instruc- 

 tion and demonstration in 

 agronomv use is made of 

 the experimental grounds, 

 greenhouse, and other 

 equipment of the plant- 

 culture experiment sta- 

 tion. The experimental 

 grounds have a total arei^ 

 of about 15 acres, and ad- 

 join the agricultural insti- 

 tute on the north (PI. XVI, 

 figs. 1 and 2). Experi- 

 mental work on this land 

 was begun b}^ Professor 

 Drechsler in the beginning- 

 of the seventies, and has 

 included trials of systems 

 of rotations, variety tests 

 of farm crops, fertilizer experiments, and improvement of cereals and 

 other crops through continued selection. The diagram herewith given 

 shows the divisions of the experimental grounds (tig. 22). The crops 

 grown on these in l!>Ol were as follows: 



Field A. — Gottinger rye. 



Field B I. — Square-head wheat. 



Field B II. — Potatoes, 22 varieties. Potash fertilizer experiments.- 



Field C. — Red clover. 



Field D. — Peas, 2 varieties, and beans. Potash fertilizer experi- 

 ments. 



Field F. — Rye, flax, winter wheat, mang-el-wurzels, barley, beans, 

 potatoes, spring wheat, oats, sugar beets, and potatoes. Fertilizer 

 experiments.
