It was Herbert Spencer who made
this definition of evolution: "Evolution
is change from an indefinite, incoher-
ent homogenity to definite, coherent
beterogenity, through continuous differ
entiations and integrations." 1t was
the mathematician Kirkman who trans
lated the definition into plain English:
"Eyolution is a change from a nohow-
ish. untalkaboutable, all-alikeness to a
somebowish and n-general-talk
able Observation-Disclosures bv continu-
GUS neutrality-suspicious. and stick
togetherations."
A new thing in fire apparatus is the
electric hose. A wire runs along in the
cotton or rubber part of the hose, con-
tinuing the connection as each section
is attached, and over this passes elec-
tricity generated by one of the engines
fiy-wheels. Connected with the nozzle
is little contrivance by which the en-
gineer can be told, although squares
| distant from the man who is PLAYING
water on fire, to turn it on, cut it of,
stop. or 90 ahead, or ANYTHING else that
can be agreed upon, by a signal which
is struck on a gong placed upon the en-
zine. III
