From the entrance hall a broad flight of stairs leads up to the 
second floor, which, so far as arrangement goes, is a counterpart of 
the one below and above it. This floor contains the forestry and 
chase museum, geodesy and physical collections, meteorological 
workroom, conference and reading-room for the professors, and 
lecture-rooms for forest science and physics and mathematics. The 
top floor holds the botanical and zoological museums, lecture-rooms 
and workrooms for the same department, drawing-room for plan 
drawing. The lecture-rooms are fairly large, well-lighted rooms, 
with desk accommodation for about one hundred students; the 
lecturer’s desk being placed at the end, at the back of which 
hangs a black board. In each lecture-room is a plan of the 
seats, which are ali numbered, and each student must write 
his name on the space representing the seat he wishes to occupy 
during the session, the senior students having the right of pre- 
ference in regard to their choice and retention of formerly occupied 
seats. 
The museums are of great interest and value for purposes of 
instruction, and are very complete. The forestry, botanical, and 
zoological collections are available for inspection by the students at 
all times ; the others require special permission from the respective 
professors. The forestry museum occupies the whole width of the 
building, two rooms and a portion of the end of the passage which 
runs through the floor being fully occupied. It is divided into 
nine divisions for the sake of convenience, viz., forest construction 
tools ; appliance and contrivances for forest protection ; manipula- 
tion of wood and bark in the forest ; wood transport ; raw products 
of the forest; wood manufactured articles; utilisation of forest 
bye-products ; forest mensuration; and the chase department. 
Under the first heading are arranged all the numerous tools and 
machines for planting and sowing, as well as for the preparation of 
the ground, These consist of many tools and implements that 
would be well worth describing if space permitted, as they are 
probably rarely seen outside the district in which they are used. 
Planting spades, rakes, ground preparers and breakers, models of 
ploughs and harrows specially invented for breaking up forest land, 
sowing machines, pruning tools, ete., are all represented, while the
