To Represent A Storm At Sea
Provide two strips of glass, whose frames are thin enough to admit
both strips freely into the groove of the lantern. On one of these
glasses paint the appearance of the sea from a smooth calm to a
violent storm. Let these representations run gradually into each
other, as in Fig. 9, and you will of course observe, that the more
natural and picturesque the painting is, the more natural and pleasing
will be the reflectio
On the other glass, Fig. 10, paint various vessels on the ocean,
observing to let that end where the storm is, appear in a state of
violent commotion, and the vessels as if raised on the waves in an
unsettled position, with heavy clouds about them.
You then pass the glasses slowly through the groove, and when you come
to that part where the storm is supposed to begin, move them gently up
and down, which will give the appearance of the sea and vessels being
agitated; increase the motion till they come to the height of the
storm. You will thus have a very natural representation of the sea and
ships in a calm and storm; and as you gradually draw the glasses back,
the tempest will subside, the sky appear clear, and the vessels glide
gently over the waves.
By the means of two or three glasses, you may also represent a battle
on land, or a naval engagement, with a variety of other pleasing
experiments.
