Marestier shows the location of the stack as being abreast the buckets on the forward side of the paddle wheels, and it has been so placed in the reconstruction. The deckhouse shown in Marestier's sketch extends from a little forward of the mainmast to a little forward of the paddle wheel axle. Probably this house actually covered the main hatch and the crank-connecting-rod hatchway; therefore, Marestier shows it too short. In the reconstruction, the deckhouse works out as between 17 and 18 feet long. Its width can only be guessed at, but it probably would have been as wide as the opening cut in the upper deck for machinery--say 11 feet. Perhaps this house contained the engineer's stateroom and that of his assistant, as well as a ladderway to the engine room. Doors on the sides of the house gave access to these spaces and to the inboard shaft bearings. Bunker hatches were probably forward of the house and outboard; these are taken as being about 2 feet 6 inches wide and 3 feet 6 inches long--large enough to allow coal baskets to be lowered through them, as well as to allow cord wood to be passed below. A fidley hatch, in which the stack passed through the upper deck, would have been a square hatch forward of the deckhouse. This hatch, about 2-1/2 to 3 feet square, would have been fitted with an iron or iron-bound fidley grating, with solid cover over. The stack could have been swivelled, to bring the elbow to leeward. The upper portion of the stack probably overlapped the lower portion at least 3 to 4 feet above the fidley coaming, and the upper stack rested on a collar bearing at the bottom of the overlap. Perhaps straps were bolted to the side of the upper stack to take heaving bars athwartships, by which two men could rotate the upper stack to turn the elbow to leeward. The bearings of the paddle wheel axle were perhaps four in number. Two, one either side of the crank, may have been secured to the engine frame just inside the deckhouse walls. Two were certainly outboard, one on each side, fastened to the topsides, as shown in Marestier's sketch of the wheel construction. The axle, probably square in cross section, turned only at the bearings and wrist pin. It may have been cast in two parts, each with a crank arm, and then joined by the wrist pin, after the latter had been turned.
