He was in a circular box about ten feet in diameter, covered with a roof and with bulwarks rising breast-high all the way round. His duty was spotting for the secondary armament, and to assist him there were two other officers and eight men acting as range-takers, messengers, timekeepers, and in charge of deflection instruments. He gave the range for the guns to the transmitting station, watched the fall of the shot, estimated its distance over or short of the target, and supplied the necessary corrections. As it was useless to expect that firing the secondary guns would be of any value until the range came down to about 12,000 yards, or to repel destroyer or light cruiser attack, there would be a long interval of waiting before he would have anything to do. Meanwhile, he went round the instruments and saw that they were all in working order, tested the voice tubes, and gave hints and instructions to his subordinates. The sky was rapidly becoming more overcast and the clouds were lower, although the horizon was still plainly visible. A message came up the voice-tube from the conning-tower, warning him to keep a sharp look-out on the port bow as the enemy battle-cruisers should be shortly sighted proceeding in a northerly direction. Every sense was subordinated to that of sight, and in the tense stillness he strained his eyes until the sockets hurt. Looking down on the ship, which was spread like a map beneath his feet, no sign of life was visible, although behind armoured side and beneath thick steel hoods eager-eyed men were chafing at the delay. It was easy to see that the ships were travelling at full speed, and the smoke belching from the ships ahead blurred his view and damaged his eyes until he remembered the pair of motor goggles he had supplied himself with. Suddenly his attention was riveted by a small patch of the horizon where the haze seemed slightly thicker than elsewhere. To anyone who had not spent long weary hours watching for just such a haze it would have suggested nothing at all, even if it had been observed. He picked up his binoculars, which were hanging round his neck from a strap, and took a long, long look. The other two officers watched his face carefully. Suddenly he dropped the glasses from his eyes and turned to his companions. ‘Yes; that’s the enemy battle-cruisers all right. They are making a sixteen-point turn. I wonder what their game is. Are they running away as they did at the Dogger Bank, or are they falling back on the High Seas Fleet. Anyhow, there’s the _Engadine_ sending up a seaplane.’ He watched the movements of the seaplane ship for a few minutes, and then heaved a sigh of relief as a gigantic bird rose in flight from her side. ‘We haven’t sighted any of their Zeppelins yet and they would be useless in this atmosphere. If I know anything of the _Engadine’s_ people, we shall get all the information we need in a little.’
