From the above trials it was found that the first prize large-class
engine weighed 6504 lbs., and delivered in one hour 11,366 gallons,
being at the rate of 196 gallons for each hundred-weight of the
engine; while the first prize small-class engine delivered in the same
time 8142 gallons, or 276 for each hundred-weight of the engine,
showing that the latter engine delivered nearly one-half more water in
proportion to its weight, than was delivered by the large one, the
conditions of the two trials being the same.
