ant on the survey proper, the work which at first was embraced 
in the professorship held by the state geologist, has been fur¬ 
ther divided so that two professors and one instructor are occu¬ 
pied the greater part of the time on the work that the state 
geologist was relieved of. This expansion has been accom¬ 
panied by a corresponding extension of all the usual and neces¬ 
sary appliances that are needed for the equipment of scientific 
departments. Latterly, however, the lack of room and proper 
facilities in the main University building where these depart¬ 
ments have been accommodated became so pressing that a gen¬ 
eral demand was made on the Regents, and by the Regents on 
the Legislature for a special building adapted to the accommo¬ 
dation of all the museum and survey collections aud the labori- 
tories and lecture rooms of natural science. This building has 
been erected at a cost, at present, of about $100,000. It will 
require still about $100,000 to finish and furnish it. It prob¬ 
ably will be occupied in about six months. 
The new Science Hall. The aceompauing plate represents 
the front of this building. It is constructed of two sorts and 
colors of sandstone native to the state. The darker one is used 
where in the figure the shaded portions appear. It is the brown 
Lake Superior sandstone. The lighter one was obtained from 
the gorge of the Kettle river a short distance north and east of 
Hinckley. It was examined carefully by the writer and reported 
under the name Hinckley sandstone, as a building stone of very 
high grade, in the chapter devoted to the building stones of the 
state, in Yol. 1 of the final report of the survey in 1882. It 
was this first examination of this rock that proved its excellence 
and called attention to it. Since then it has been introduced 
extensively into the markets of Minneapolis and St. Paul, and 
perhaps supplies more material for construction than comes 
from any other single point in the state. This result may be 
cited as one of the immediate benefits of the survey. Being in 
an inhospitable and then inaccessible region it probably would 
have remained to this day unnoticed. 
The building is 214-J feet long and 77 feet wide, and of fine 
architectural appearance. The left end, the more distant from 
the reader, is intended for use as a museum with library and 
reading room for the use of the professors on the basement 
floor. The central portion is divided among the instructional
