The Military Academy, although in a i*espectable state last year, 
has since evidently improved in every respect. The regulations which 
had been under experiasent have been faii-ly tested as to their etli- 
ciency; and have, with some additions and modifications, been ap- 
proved and printed for tlie use of the it)stitution; so that each indivi- 
dual possessing a coi)y may conform with exactness and readiness to 
their injunctions. The number of Cadets at this time attached to the 
Academy amounts to two hundred and fifty-three, and the number 
which has been graduated and attached to the Army this year, 
amounts to thirty-six. 
Respectfully submitted.
