long as the last cake is in the upper cham¬ 
ber the room below is kept cool. 
The cold storage chamber is practically 
underground, and it is entered by stairs 
from the outside. These stairs may be 
placed so that they begin at the back 
porch. This will make it no more diffi¬ 
cult than to enter the cellar of the house. 
The underground storage room should 
be excavated to the required depth, and 
about twelve feet square. An ice house 
of this size will store about twenty loads 
of ice, which should be sufficient for the 
ordinary family. The lower part of the 
building is used for a cold storage room, 
and the upper part is made for holding 
the ice. The division between the two 
rooms must be perfectly air tight, and a 
moderately good conductor of heat. 
The walls of the building should be 
built up in the usual way of stones, bricks 
or concrete blocks laid up in cement mor¬ 
tar. The tighter the wall the better it will 
be. The floor of the storage room should 
be made of concrete laid over a surface 
of six inches of loose stones. There must 
be a space for sawdust or layer of still 
air between the wall and the inside of the 
room, and this can be made by inclosing 
the room with matched lumber, leaving a 
space of at least ten inches. This space 
is carried up clear to the roof, as will be 
seen by the illustration. 
The beams or girders for carrying the 
load of ice in the upper chamber must be 
unusually stiff and strong. They must 
be heavy enough to carry twenty or more 
loads of ice. In the center of the storage 
room a strong pillar or post or a series of 
two or three should rest on a stone foun¬ 
dation to help carry the upper floor. The 
beams should rest their ends on the stone 
wall where they can be embedded and 
closed up with concrete. 
The floor of the ice room must be made 
of zinc sheets so that any water dripping 
from the ice above will not leak through 
to the storage room. To make the floor 
waterproof strips of rubber sheeting are 
first placed on the floor, and the zinc 
sheets nailed firmly to it. This makes the 
joints waterproof and airproof. The zinc 
flooring has a slope to one side and a 
drain pipe connected to it to carry the 
water away outside. 
It will be noticed that the blocks of ice 
do not rest on this zinc floor, but on a 
platform built up above it a few inches. 
This is to prevent the ice from tearing 
and breaking the zinc when being put in. 
It also provides an air space underneath 
the ice which helps to preserve it. Per¬ 
fectly dead, inert air keeps ice. It is cir¬ 
culating air which melts it. 
If the foundation of stones is carried 
up to the top of the cold storage room, 
the upper part of the building can be fin¬ 
ished off in bricks, concrete blocks or 
with lumber. A space of at least ten 
inches should be left between the wall 
and the ice chamber for sawdust. This 
space incloses the ice on every side, and 
on top a layer of sawdust is also pro¬ 
vided. 
Trees require occasional expert attention to keep them in 
healthy condition. Often times trees that appear sound are slowly 
dying. They may topple over any time, causing property loss, if not 
loss of life. Protect yourself by having your trees examined at once.

this work, when requested, without cost. The charge of afterwards treating 
diseased trees in many cases is no more than the cost of carting dead trees 
away. Don’t let any man touch your trees unless he shows you credentials 
proving him qualified to perform the work. All graduates of the Davey Insti¬ 
tute of Tree Surgery carry such testimony, and are employed by the Davey 
Tree Expert Co. WE NEVER LET GOOD MEN GO. If you are the owner 
of trees they are worth saving. Write to-day and arrange for a free examination.
