The military finish I noticed in the cadet school the day before impressed me favorably. H. and I went to the aviation field in Sofia; most of the machines were Ottos.
In the afternoon, I went to the flying school with H. Our guide, Captain P., showed us as special attraction a Blériot, which he had. The school is still in the first stages of development. From there we went to the resort called Banje, which is nicely located.
In the evening, I was at supper with a military attaché, and met Prince Kyrill. He interested me very much, and talked quite intelligently about a number of things.

Early in the morning, I reported to the Bulgarian Secretary of War, who conversed with me for a long while. He is small in stature and talks German fluently. Then I visited a cavalry barracks, where I also saw the new machine-gun companies. Toward evening I took a stroll in the Boris Gardens, and admired the beauty of Sofia.
