Baldwin, Thomas
Aeronautics -- Early works to 1900; Balloons -- Early works to 1800
87. The Balloon continuing its eccentric Movements from _Side to
Side_ across the Meadows; yet still gliding _down_ the River, in a
North-West by North Direction, almost at right Angles to that which
it _before_ had held; consequently _towards_ the Sea, and in a Line
which continued must pass throu’ the Center of the Channel: some Step
it was necessary to take, and +soon+. By throwing out Ballast, the
Balloon woud instantly rise: but it woud probably, as _before_, rise
into +a Calm+, and therefore _descend_ nearly in the same Line: which
woud merely _protract_ the Time till the Balloon had reached the Center
of the Channel: where, having no Resource, the Ballast being then
expended; there might be some Risque in waiting for a Vessel, tho’ the
Balloon woud not for +several Hours+, have lost its _levitating_ Power,
so as to have sunk with the Aironaut. To him however it immediately
occurred, that there might be an +under+ Current of Air, as usual in
the Middle of the Day, blowing from Sea to Land: and, that if the
Balloon was made to descend +quickly+ into the Sea-Breeze; it might, in
a few Minutes, be carried so _far_ within the Country, as to be _soon
beyond_ the Influence of the _Sea_ and _River_: and +then+, by throwing
out some Pounds of Ballast, woud return into the _upper_ Current, and
pursue a _safe_ Course towards Manchester; or even towards Prescot and
Liverpool, if an easterly Wind prevailed _above_.
88. In Consequence of these Expectations; he looked downwards _towards_
the Sea, _then_ wholly _invisible_; tho’ the Murmuring of its Waves was
_more_ plainly heard.
[Sidenote: Smoke blown to Land by a Sea-Breeze.]
+Thick Smokes+ were distinguished issuing from _different_ Places along
the Marsh near the Coast: and _apparently_ skirting the Ground, as if
impelled by a _brisk_ Wind from the Sea.
89. No Time was to be lost.
The Balloon having reached the Cascade; and continuing to move more
regularly along the Course of the River, past the _Bridge_, and
proceeded to _Rock-Savage_.
[Sidenote: The Balloon still going to Sea, the Mouth was opened.]
90. The Neck or _Mouth_ which remained shut, by its own Pressure
against the Outside of the upper Hoop, as _it_ lay over it; was
instantly brought within the Hoop, and set +wide open+ in a
perpendicular Situation.
Not more than a Couple of Minutes had elapsed before Sounds were more
audible and louder.
Cattle and Corn in the Fields became visible.
[Sidenote: Ballast in Hand ready to throw out.]
