advantage. A vessel OF 1000 tons. with
spacious accommodations for 600 pas
sengers and with machinery developing
$1,000 horsepower would have speed
OF about 30 knots. as compared with
the 10 TO % knots, ns the present vessels
OF like size and accommodation. a
special unarmored cruiser, with scanty
crew accommodations, but an arrna-
ment OF guns and torpedoer. would
have interesting speed possibilities.
With dimensions double those OF the
30-knot destroyers, and plates OF double
thickness. specially strengthened. there
would be two tiers OF wntcr-tube boil
ers. and eight propeilers OF nine feet
diameter. revolving at about 400 revo-
iutions per minute. and the speed would
be nearly ~ knota. For this speed the
coal supply would last eight hours but
for 10 to II knots the economy would
exceed ordinary vessels.
The manufacture OF mineral waters
is criticized by "a French chemist, T..
Carries, who finds TINT very often too
little care In exercised. The great es-
Hcntials are the Judicioua choice OF
soft water. the use OF perfectly pure
carbonic acid. and the exclusion OF
valves made partially Of lead. In dimes
OF epidemics special attention should
be given to the meteorological purity
OF water, and II should be remembered
that microbca-as those OF typhoid
live longer In seltzer water than In
ordinary water.
