A man-of- war has Its vitality enor:.
mously diminished If certain portions
of it become too cold. in much the
same way as its human tenants, Ac:
cordingly its boiler and steam pipes
are clothed with Jackets" In some,
cases the jackets are made of ordinary
blanketing, others of ibrous clay-like
composition or even Of close grained
wood. In general the material used
for a ships underclothing Of this de
scription consists of mineral wool. Il
However. the great ship Is more like
ly to suffer from the effects of heat
than from those Of cold, There is al.
ways the danger owing to the newer
type Of machinery employed that the
powder magazines may get too hot! II:
In the latest; men of-war: the stores
are surrounded BY a thick coating Of
mineral wool Mineral wool. BY the
way. has nothing whatever to do with
wool. as it consists Of mass of snowy

Enormous quantities Of this strange
variety Of wool are used on board for
the purposes of undertaking the bulk:
heads and the more delicate portions
Of the ships body. This invaluable
substance acts equally well as pro
tector from heat and from cold. It is
such "a remarkable uonconductor $of
beat that it Is used for covering the
i refrigerators and the, cold storage
chambers and therefore the explosive
i stores !,ssis y; !. Il
