He appeared to have reached his conclusion. Closing and locking the outer door, he walked over to the boathouse, at the pier of which the Magnolia had been secured by the boatmen as soon as the work of the night was completed. Here again he stopped and made a survey of the neighboring swamp, which separated the lawn from the bank of the Green. Then he went over to the bank of the river, and followed it down stream. At this point a bend of the river above forced the water of the stream over near the opposite shore, while half-way across from the bank on which he stood, the waters from the river and the creek had washed in the mud so that it formed a bar on a bed of rocks, and the descent here produced the rapids. The water for half a mile was considerably troubled when the streams were full, while it was deep enough on the other side to permit the passage of the steamboats that plied on the river. Levi continued his walk in the road, with Green River on one side and on the other the swamp which bordered the creek to a point near its source. The swamp was impassable on foot or by boat. It was better than a wall in the rear of the mansion, and the marauders of Titus Lyon could not approach from that direction. Farther along was a broad lagoon or pond, connected by a wide and sluggish inlet with Bar Creek. This could be crossed with a boat; but the approach to it from the spring road over the low ground was difficult and dangerous. The overseer knew the whole region very well; but when he had viewed it again in the light of impending contingencies, he seemed to be entirely satisfied with the situation, for his chronic smile was on his round face, though no one was there to see it. He went to the shop, which formed part of the carriage-house, and began a survey of the lumber on hand there. A couple of three-inch oak planks were pulled out from the pile. He measured and marked them with a piece of chalk, and then left the shop. Among the plantation hands were carpenters, masons, painters, and other mechanics, more or less skilful, though none of them had regularly learned a trade. Some of them had become quite expert in the use of tools, and could do a very respectable job, especially the carpenters. Levi was himself a "jack-of-all-trades," and he had trained some of them to the best of his ability. When he came out of the shop he sent Frank the coachman to call the three carpenters, who worked in the field most of the time. The colonel had given these men names to suit himself, and they were proud of their cognomens. "Shavings" was the most skilful of them, and was the "boss" at any job to be done. "Gouge" and "Bitts" were only fair workmen, but they did very well under the direction of their foreman.
