He determined to make an expedition up the chimney on that third evening, if circumstances proved favorable. After the evening meal of bread and water he got Ben to use his strength in bending down the bars. Then he crawled through and began to ascend. It was a tight fit. The chimney was narrow; but Jack, never stout, had grown thin on the prison fare, and he wormed his way up by the aid of projecting bricks left for the chimney-sweep; those were the days of chimney climbing. The flue was not very dirty; evidently no fires had been lighted below for a long time. He reached the top without mishap. There was no chimney-pot. Looking cautiously out, showing as little of his head as possible, he saw the sea rippling far below in the distance, shining ruddy in the glow of the setting sun. A strong easterly breeze was blowing. To the right lay the harbor and town. To the left were two sloops and three or four praams; alongside the nearest sloop a coasting brig; then two fishing smacks. A cable’s length from these lay the _Fury_, now apparently refitted with new main- and topmasts, and eastward of her, a little farther out, a lugger and another smack. Jack guessed that, besides the _Fury_, only the sloops and the praams were likely to be armed with cannon, though the lugger might carry a small gun. The immediate surroundings of the château were out of sight, except to his left, being screened by the parapet of the flat roof some feet away from the chimney. Except at one point, where the roof of an outbuilding rose nearly to the same elevation as the part where he was perched, there was a sheer drop of fifteen feet from the top of the chimney-stack. It was a sloping roof, and Jack made up his mind to crawl down it until he came to a chimney of the outbuilding, from which a thin spiral of smoke was rising. But he waited until the dusk had deepened before he thought it safe to emerge. Then he crept carefully down till he reached the smoking chimney. The roof there was not quite as high as the other; the drop was about five feet; and he guessed from the position that below the chimney were the servants’ quarters. Two other chimneys beyond were smoking; these, he thought, must belong to the rooms occupied by the guard. The other chimneys, from which no smoke was rising, could only be reached by dropping some twelve feet and climbing an equal distance; and to do that would involve the risk of being seen or heard.
