lY IMTRODUCTION. 



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

 appropriatioa for the purpose of ilkistrating tbis 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 sev- 

 eral months 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 to the interest and exertions of that well known 

 friend of popular education, the Hon. Elmer Baldwin, of LaSalle coun*ty. 



Respectfully submitted.
