made to cover, and those of the Biological Station, with some 
incidental general work naturally growing out of the operations 
of these two establishments. I see no reason why the State of 
[llinois should not provide in a suitable manner for the ener- 
getic prosecution of this Survey work which it long ago author- 
ized, and I propose, consequently, to ask of the next legislature 
a suitable sum for this purpose and a separate sum for the 
economic investigations for which the State Entomologist is 
responsible. I think, also, that the legislature might well be 
asked to enlarge the field of the State Laboratory of Natural 
History to include an economic geological survey, with such 
topographical work as this might require, and a biological sur- 
vey of the water supplies of the State, conducted with special 
reference to sanitary interests, a subject which is certainly not 
less important in some of its aspects than that of their chemistry. 
For details respecting the various departments of the work 
of the Biological Station you are respectfully referred to the 
appended reports of the Station Superintendent, Dr. C. A. 
Kofoid, of Prof. A. W. Palmer, Director of the Chemical Survey, 
of Mr. Chas. A. Hart, Entomologist of the Station, and of Prof. 
Frank Smith, who served for a time as its Assistant Zodlogist 
and as principal instructor in the Summer School. 
Respectfully submitted. 
S. A. Forsss, Director.
