stations by pipe lines, whether through

now being delivered in this way, though
A on no very extensive scale as yer, in three
or four of our cities.
Early in the twentieth centuty the house

much matter OF course to turn on the
cold in his house in summer as to turn
On the heat in winter, and, by the help

mental stage, city dwellings generally viii

is controlled during the cold season, so
!. the refrigeraGng apparatus will be regu-
4 lated in the dog days, and any undue ele-
vation rectifed by the mere turning of a
key between thumb and finger. Mean
while, the domestic "icebox," erstwhile
4 so termed, will do duty without a scrap

h agency with an automatically governed

shape OF ice. Consequently it cannot be
