A good deal of woodwork had been cut away and thrown overboard, though far too much of it still remained, and on several ships there was a dangerous quantity of carved ornamental wood on the upper works, much of it all the more inflammable because it was gilded and lacquered in bright colours which it was the practice to clean with oiled rags. The thin steel roofs of barbettes, and the shields of many of the guns, had been removed, as the "Tsi-yuen's" experiences in the fight with the "Naniwa Kan" had shown that such light steel did not keep out the shells of the Japanese quick-firers, but served only to ensure their bursting with deadly effect. Sometimes a gun-shield had burst a shell, which if there had been no such attempt at protection would perhaps have passed harmlessly over the heads of the gunners. Round the barbettes of the ships sacks of coal were stacked as an emergency method of strengthening these defences. Of coal the fleet had an abundance, but it was woefully short of ammunition, and much of what was on board was old and defective. If Ting had had more professional knowledge and training, he would have been more anxious as to the probable result of a battle. Where were Admiral Ito and the Japanese fleet? Early in August he had crossed the Yellow Sea with his cruiser squadron, and shown himself before Port Arthur and Wei-hai-Wei. He drew the fire of the seaward forts at long range, and replied with a few shots, but he made no attack. He was engaged only in a reconnaissance, and was quite satisfied when he ascertained that the Chinese ships were remaining in harbour. He then returned to the Korean side of the Yellow Sea, and till nearly the middle of September was employed in escorting the convoys of transports from Japan, and protecting the disembarkation of the reinforcements they were bringing to Korea.
