16 brilliant fixed cases reported.
4 double Saxons illuminated.
4 five-pointed stars.
This piece will be much better if it has a brilliant triangle, or double
triangle, wheel in its centre. If a double triangle be used, it will
begin first and last out through the performance of the piece. The
sketch given at fig. 102 will speak for itself as to design, shape,
outline, &c., &c. But I may as well suggest in this case, as I have in
the others, an order for its changes, or _mutations_, as the authorities
delight to call them.
I will suppose that you use a brilliant double triangle wheel in the
centre. This, of course, has six small cases upon it, and should have
also a colour in its centre. Fire this wheel first, and let two of its
cases be consumed. Then fire the four coloured lights which are to be
substituted for the five-pointed stars. Two of these coloured lights may
be _green_, and two _purple_. Then when two more of the cases on the
triangle are burnt out, strike in the double Saxons and the brilliant
fixed cases.
This piece will, of course, take you some time to make, and will require
some patience and a good deal of nicety and precision in its
arrangements. But it will fully repay you for all the pains that you
bestow upon its preparation. I think the colour on the double triangle
wheel had better be purple; those on the Saxons red; the other four
colours, as I have said, green and purple.
At fig. 103 I have drawn the wooden centre of a double Saxon to show you
an easier way of fastening on your colours. You have simply to bore a
hole with a small bradawl through the clay end of the coloured light
case, and pass through it a piece of small soft iron or copper wire. The
ends of the wire are then bent round the wooden centre, and twisted
together tightly at the back.
Fig. 104 represents a settle proper for the making of Saxons. It is to
be fixed or screwed into a block, such as I have drawn in the
illustrations for Roman candles.
