jY IMTRODUCTION. 



I may here add that the lateness of the date at which the hill for the 

 appropriation for the purpose of illustrating- this report passed the 

 General Assembly, and the time required for preparing the engravings, 

 have necessarily caused a delay in the publication of this report of se^ 

 eral mouths beyond the usual time. 



I also deem it proper here to put on record, that the preparation of 

 the above mentioned bill, and its passage through the General Assem- 

 bly, were largely due fo the interest and exertions of that well known 

 frieud of popular education, the Hon. Elmer Baldwin, of LaSalle county.
