20 REPORT OF THE 



taut work. I beg leave to submit the usual statistical returns, 

 together with the list of the names, occupation, and length of 

 service of all employes during the year; this list comprises 

 a large number of men temporarily employed during the emer- 

 gent seasons of work, and were required to supplement our 

 ordinary force. These were discharged, in all cases, as soon as 

 the necessity ceased. 



Respectfully submitted, 



JOHN Y. CULYER,
