    The owl has been very active 
 today.
                    12th.

    Have been very busy today.

Letter from chum on little bits of paper. Exercised some. No time to study. Must work tonight. Whether I succeed in passing the ordnance Board or not I am determined to keep up the study of mathematics. It is the true kind of mental discipline that we get from such studies. A good mathematician ought not to have weak thoughts on any subject.

         Played two games of 

chess with Lieut. Col. Perkins tonight.
