the front will turn up fquare. The Aider is hopped into the
till by a couple of pins which run in grooves ; and when it is
pufhed home, before it can turn up, a hollow muft be worked
in the bottom of the till, to give room for the angle of the riling
part of the Aider to turn in. When the Aider is turned up, it is
kept in its place by a fpring-catch, which ftrikes into a plate
put on at the under fide of the top of the till. And obferve,
that when the front is up, it fliould be rather within the carcafs
of the till, both for the purpofe of letting the till go eafy down,
and to admit of a fiip of thin green cloth at each end, fo that
when the front is turned upon the top of the Pembroke table it
may not fcratch it.
Another method may, however, be propofed, and which
■will be attended with lefs trouble; only with this difadvantage,
that it takes off a little of the height of the drawers.
The Aider, being made in two parts, may be hinged in the
manner of a card-table top, which, when it is folded over, can
be pufhed to its place. But obferve, that the under top muft be

being flopped in after the manner of the other; fo that when it
is drawn out, the upper top will rife and clear the drawer
fronts. If the Aider be made in this manner, the drawers can
