ou the truth, I think I was just a little
bit ashamed about the thing, because I had to pull it off. I didn't like
the looks of it after I got it on."

Two small tanks, each with a capacity of approximately two gallons, were
mounted over the engine in the positions they still occupy, the one on
the left for gasoline,[23] the other for water. The small fitting under
the gasoline tank has a thumbscrew shutoff and a glass-sight feed tube,
leading to the carburetor. The water tank, an inch longer than the
gasoline tank, communicates with the water jacket of the engine through
two pieces of half-inch pipe, entering the jacket from above and below.
The overflow tank, holding just over a gallon, is suspended between the
rear axle and the flywheel.

A number of mufflers were constructed for the engine.[24] The first
experimental one was built of wood, being a box 6 x 6 x 15 inches with a
hole for the exhaust pipe in one end and a series of small holes in the
opposite end. Inside, Frank arranged metal plates which were somewhat
shorter than the depth of the box. Every other one was attached to the
bottom of the box; the intermediate plates were fastened to the top.
This contrivance muffled the sound considerably, but, as might be
expected, soon began to smoke. There can be little doubt that it was
replaced before any of the outdoor trials began. Another type consisted
of a cylindrical metal shell, perhaps six inches in diameter and ten or
twelve inches long. Here a series of perforated baffle plates were
inserted, with alternating solid plates having parts of their external
edges cut away. Two bolts running the length of the muffler held on the
cast-iron heads in a manner quite similar to the Model-T Ford mufflers
of later years. Though partially satisfactory, Frank, in a November 6,
1957, interview, complained that it made a metallic sound. Perhaps this
was the muffler he used from September to November 1893.

On August 28 Frank wrote to Charles saying the carriage was almost ready
for the road and that he hoped to take it out for a test on the coming
Saturday, "off somewhere so no one will see us...."[25] There is no
evidence showing whether the amount of remaining work permitted the
proposed trial on September 2. The body was finally replaced on the
running gear, at which time it was fo
