il<> not appear to be more than signal poles and 



apparently were nol fitted with sails; however, s e 



European lateeners did have triangular topsails ovei a 

 lateen and it is possible the Battery may have carried 

 such sails. ( '.onsidcring the stability and displacement 

 nl the Battery, the rig is very small and not sufficiently 

 effective. Shrouds were not required; the masts were 

 supported by runners that were shifted when the 

 yards were reversed, and in tacking. Apparently the 

 jibstays also could be slacked off so that the lateen 

 yards would not have to be dipped under them. 



The inboard profile is on tracing papei and the 

 notes are in French. This drawing is of a simplified 

 hull form having Hat-bottom hulls with chines. It is 

 possible that this is a tracing of a preliminary drawing 

 obtained by Marestiei 01 Montgery, but no documen- 

 tation can be tumid. Its importance is thai is shows 

 in some detail the engine and boilers, as well as the 

 wheelbox, and another drawing of the paddle wheel, 

 more or less duplicating the w heel shown in the I ).mish 

 pl.m. No details of the deck arrangements are show n 

 in any of the plans, except for the dome skylight over 

 the fireroom in the boiler hull. 



Both the lines plan and the inboard drawing show 

 construction midsections and hull connections. I hese 

 plans show that the engine was not inclined, but rather 

 was vertical, contrary to Fulton's patent drawing. 

 I he piston rod and the crosshead obviously passed 



through its gun deck in a large hatch. Also U is plain 



that there must have been large hatches afore and 



abaft the wheelbox in make the stepped wheelbox 



construction desirable. There also must have been 



a hatch in the gun deck under the domed skylight. 



It is improbable thai the engine and skylighl hatches 



were used for ladderw.ns. passing scuttles, or aim- 

 panionway s. 



The boilers are shown in the inboard profile about 

 as described and drawn by Marestier but with two 

 Stacks on each boiler, one to each line; Marestiei \ 

 sketch in his report on American steamships shows the 

 Hues ,,1 ea< li boiler trunked into a single stack. The 

 battery had two boilers and the stacks are at the 



boilers' hrc-door end. The steam lines came off 

 the crown of the boilers and probably passed through 



the ends of the w heelbox to the engine; a trunk for the 

 steam lines would undoubtedly have been necessary. 

 The engine is shown to have had counterbalanced 

 side levers, one on each side, and a single flywheel on 

 the outboard side. The cylinder is o\ er the condenser 

 or "'cistern." connected by the steam line and valve 

 box on the side. The cylinder crosshead is shown in 

 the inboard profile to ha\ e reai hed the undei side ol 



the beams of the upper (leek. The crosshead wa^ 



connected by two connecting rods to the side levers. 

 These levers operated the paddle wheel by connecting 

 rods to cranks on the paddle-wheel shaft. There is
