The book gives a thorough and accurate
description of this wonderful system of
Jail building, and it is well wo:th perusal

~tiaries, either from an outside or inside
standpoint.
The contents of the work show the
early history Of prisons down to the
present day; the manner aud method
OF escapes, as p%rseticed by thieves; how
to construct an ~impregnable prison us-
der the Cook & Heath perfected system,
in which cast-iron is used; the Auto
matte prison alarm, which prevents a
prisoner from escaping from his cell,
although he may have the best and most
approved kit Of burglars tools, because,
under this system the walls are double
and between them is sand which runs
and fills up the cell whenever the wall is
bored or pierced through, and when the
sand runs out to a certain point an
alarm-goug is sounded.
The wonderful invention consists 10
making the lining Of strong cells entirely
Of csst-iron plates, which form the top,
bottom and sides Of each cell; in window
frames and sash constructed of cast
iron, made Of a single casting, with per
forations formed in the process of man
ufacture; in putting the iron work frs
in position and increased in wooder
bulkhesding, after which the brick o
other walls are built up against the bulk
heading-the compound walls Of th,
cells being thus built from within out
