and the evident sympathy they have shown at all times with my work 
I 'am' also under obligations to the Illinois Central and Chicago 
Northwestern railroads for passes when on duty as entomologist, and 
especially to J. F. Tucker, Esq., manager of the former, who has 
always been ready to aid me in my work whenever he could do so, 
by granting facilities for visiting different sections of the state. 
I remain yours, very respectfully, 
CYRUS THOMAS.
