Beneath the main deck the internal
arrangements of tho Boston and At
lanta are very similar to those beneath
the gun dock of the Chicago. There
are eight complete transverse bulk
heads extending to the main deck, di-
viding the ship into nine compart-
mepts, one less than the Chicago, as the
Boston has single screw and the engines
occupy only one compartment.
The machinery spaces, extending over
a length Of 100 feet, are incloscd by
protective steel deck u in. thick. Special

1t seems advisable to draw attention to
fact that the Chicago, drawing 20 feet in,
extreme lraught, can with safety enter thi
two ports on the Atlantic coast; the Boz
and Atlanta, drawing Is feet 6 inches
can ontbr only six ports from which
Chicago Is debarred, namely, New Bedf

napolis, and Tampa. If the Chicagos drau
had been two feet greater she would be
