seven o'clock
I waited for the owl call -- `` two times , then stop soft in middle . '' And now an electric torch flashed where the sentry on my right was posted , and I froze , wondering if it were directed at Smilax . But no challenge came . In a very short interval it flashed again , and the fellow called in military style : `` Post one , seven o'clock , and all 's well ! '' The voice at my left took it up : `` Post two , seven o'clock , and all 's well ! '' From somewhere beyond Sylvia 's island the third guard called post three , and silence followed . I was glad to find that they called their posts .
