Taking a
certain amount of gas out of the balloon is equivalent to taking on
more ballast, while by condensing this gas into a large reservoir, it
is not allowed to escape, and when necessary can be sent back into the
balloon and thus prevent the throwing off of ballast. Coal gas, under
a certain pressure, becomes heavier than air (or at least equally
heavy), and thus the gas pumped out of the balloon will of itself
serve as ballast. This invention will enable the balloonist to keep
himself at a uniform distance above the earth, will prevent the
carrying of so much ballast and the expensive waste of gas, and will
enable him to keep afloat at least ten times as long as by the old
method. I have made a model and tested the above theory.

Little Sutton was an old house, parts of which were in existence
before the time of Cromwell. It is situated in a picturesque old
garden, surrounded by ivy-clad walls and fine trees, one of the cedars
being extraordinarily large and perfect, its huge branches covering a
space of over 90 ft.
