Although the heating Of cars by hot
nva+or has been practiced for a LONG
time, we believe the application 10
florists wagons is somewhat or a nov
eIty in the development OF hot wa'er
heating. This warming apparatus
been designed In Brooklyn, \. I. Inc
firm conducts a store on Fulton street,
BROOKLYN, which is supplied by its ex-
tensive green houses at Bay Ridge, a
distance of some five miles from the
store, Not only in making this long

carried back from the header, drop

This. Of course in cold weather would
mean the freezing Of water in the pipes
and their consequent rupture. To pre-
vent this water is drawn off through
a plug cock which has a screw thread
on the outer end, enabling a hose to
be attached to 1t and the apparatus
filled with water. The specially de
signed boiler consists of two caSt-iron
boxes, both Open at one end. The
larger box Is about Is inches long IL
inches high and 8 inches in width. The
smaller casting is about 1 inch smaller
in each dimension and the space be-
tween the two shells contains the wa

a slight taper SO as to allow he pat

mold. To prevent radiation of heat
from the boiler the whole is covered
with / inch Of mineral wool incas9d In
a wood Jacket. A caSt-iron front bolted
on 10 the front end Of the boiler and
this Is pierced for three 1-inch tubes
and n fire door. The back Of the boiler
is turned toward the front Of the
wagon. and t. obtain a sufficient
draught a defector is provided so as to
cause a current Of air to flow through
the hampers under the fire. The lower
part Of the deflCctOr turns upon a hinge
so that it may be swung out Of the way
if desired. A charcoal fire Is made in
a basket Of wire netting and the has
ket is put in the boiler. TO insure a
more uniform distribution Of the air

basket to the fire pipes wera intro

front by lock nuts. They are Of such
length as to extend well back over the
fre so as TO prevent the air from
taking a short cut on entering the fur
mace and only going through that part
of the fire that is nearest the furnace
door. Ordinarily the charcoal fire viii

be ~replenished. Starting with cold wa

IRENE weather to heat the van up to
such temperature as will permit the
