s is sandpapered down to allow for the skin and gouged out at
the bases of the fins and tail. The head too is not reproduced on the
cast.

When the skin is ready to apply, coat this plaster cast with some
nonporous modelling material. A mixture of thin liquid glue and whiting
is good for this. Some paper pulp is put inside the head and at the
junction of body and fins. Shape from the outside with the fingers.
A piece of wood should have been placed in the back of the plaster cast
when making same, in order to fasten to a panel by screws from the back.
Paint the wood with melted paraffin before putting in the wet plaster or
it may swell and subsequently shrink enough to crack the cast. By either
of the preceding methods the entire fish can be mounted if desired.
The opening cut should be made from head to tail along the lower edge of
the body in most scale fish and will require some neat modelling to hide
as both sides are to be on exhibition.
Entire fish are usually supported by metal standards rising from a
wooden base. Such standards are preferably of brass, threaded and fitted
with nuts and rosettes at both ends. Two nuts at the lower end clamp the
base and with the upper end inserted in the back board, the upper nut
will adjust the fish at the right heighth. The rosettes cover the nuts
and add a finished appearance.
Especially adapted to tarpon and other ponderous fish are medallions
mounted on paper. To do this a half mould is made as described, the skin
removed, cleaned, poisoned and replaced in the mould. Then it is backed
up with numerous layers of soft paper, well pasted and pressed in with
the hands. Let these layers of paper overlap the mould at least as much
as the margin of skin left on the back.
When a sufficient thickness is attained fill the hollow form loosely
with crumpled paper or excelsior and fit in place a back board of light
wood. Nail through the margin of skin and paper into the edges of this.
If a number of large holes were made in the back board it will expedite
the drying out.
When partly dry, remove from the mould, painting and finishing as before
when completely dry. By this means the contour of large fish is
absolutely reproduced and the finished work is extremely light and
durable.
Many of the smooth skinned fishes are impossible to mount
satisfactorily, a cast is the best we can do for them.
