The terrific speed, and the skilful manipulation of the seaplanes that prevented the presentation at any time of a broadside target, soon safely carried the daring airmen far out to sea.

Reporting to the admiral of the fleet, Lieutenants Moppa and Atlass presented Billy Barry and Henri Trouville with such glowing words of commendation that the lads quit the quarterdeck with very red faces.

The supreme assemblage on the hill had its problems, but no more intense interest therein than these aerial experts manifested over the display of the greatest of all aeroplanes—the Russian “Sikorsky”—just received for particular use in the Black Sea fleet, the second of its kind constructed, and in which achievement of one of his subjects the Czar himself had been reported as taking personal pride and keen practical interest.
