I T is only fair that the country should 
now turn the tables upon the city. 
Every bit of water equipment 
which for so long has been monopo¬ 
lized by those who have city water 
pressure is now within the reach of the 
country, making it, with its natural 
advantages, an ideal home not alone 
for children, but for everybody. 
A V-K Water Supply System will 
take care of any problem of water dis¬ 
tribution anywhere, furnishing a stand¬ 
ard water pressure of 50 pounds,— 
enough to throw a stream over the 
house.

Good Air in the Home 
(Continued from page S3) 
air agitators such as fans, etc. The 
theory is that, as the pores of our skin 
exude moisture, the body is comforted 
and cooled and the nervous system 
stimulated by its evaporation which is 
effected more readily by constantly 
moving air. Moving air, however, does 
not mean a draught. 
In the ideally “atmosphered” house, 
the doors and windows are ideally 
placed so that the warm air exits from 
the top of the room and the cold air 
comes in from the lower parts of the 
rooms (such as lower windows or well 
placed air intakes). Thus, the air is 
moving without the least draught. 
But why do humans need special air 
treatment? For the simple fact that 
human beings have different capacities 
for air consumption, or converting the 
air inhaled into carbon dioxide as it 
is exhaled. Scientists have found that 
a woman exhales 600 cubic feet of car¬ 
bon dioxide per hour; young men, 614; 
young women, 4S3 ; boys, 363 ; girls, 343. 
Consequently the air has to be con¬ 
stantly renewed. In the average room 
the average air change is one to two 
times per hour. In the well-built house 
it is two to three—due to fireplaces, 
windows, doors, etc. 
The requisites for good 
ventilation are: 
1. Equable tempera¬ 
ture from about 60° to 
65° Fahrenheit, and the 
moderate relative humid¬ 
ity or moisture of 45° to 
60°. In order to keep 
the room moist in winter 
it is well to keep a pan 
of water on the radiator. 
Regular humidifiers can 
be bought for this pur¬ 
pose. 
2. Clear air, free from 
impurities such as dust, 
insects, oily vapors, soot, 
etc. 
3. Odorless air, free 
from gases and vapors. 
4. Air in motion; but 
the motion must be ac¬ 
complished without those 
objectionable blasts of 
wind that so frequently 
startle you in some 
houses which are sup¬ 
posed to have the most 
up-to-date equipment. 
Air is no mysterious 
chemical combination. It 
is a mechanical mixture 
of 21 parts of nitrogen, 
79 parts of oxygen, from 
0 to 4% of moisture, and 
usually 4 parts of carbon 
dioxide gas per 10,000 
parts of air. So it need 
not distress anyone to 
effect a good clean sup¬ 
ply of air and equip the 
house with some of the steadily im¬ 
proving devices now on the market. 
The Places to Ventilate 
Any device to be useful to the home 
must, of course, be convenient, eco¬ 
nomical, safe to operate, and durable. 
Let us begin with the kitchen; for 
there ventilation is more necessary than 
any place else in the house. 
Not only is it difficult to keep the 
kitchen in equable temperature, but to 
have it cool often means a draft, and 
a draft means a cold for the cook, and 
a cold for the cook means danger to 
the whole household. 
Then there are odors from the 
kitchen. These are continually getting 
loose, unless the door of the kitchen 
is kept closed (which is trying) and 
infecting the house prematurely with 
the taste of dinner. All of which is 
uncomfortable and gives the home a 
commonplace tenementy atmosphere. 
Your home may be judged by its 
amount of laundry and cooking odors! 
The fewer, the better. Did you ever 
think of that? 
The cellar is another important room 
to keep well aired and should be pro¬ 
vided with windows and 
doors to formulate a cur¬ 
rent of air. Pantry and 
laundry, too, should be 
built with ventilation in 
view, in order that, as in 
the kitchen, these rooms 
can be kept sweet and 
savory at all times and 
under all ordinary con¬ 
ditions. 
Without extra ventila¬ 
tion apparatus, the ordi¬ 
nary air in a room cools, 
and as it cools, it falls, 
and as it falls it is heated 
and rises again—keeping 
up a rotary circulation. 
Remembering this fact, 
we can put into opera¬ 
tion in our homes these 
simple practices: 
1. Lower windows 
from top and bot¬ 
tom so that the 
warm air will go 
out at top and cold 
air come in at bot¬ 
tom, starting the 
circulation of air. 
If not too draughty, 
have a door open 
opposite the win¬ 
dows, or use a 
draught board 
which can be easily 
placed on window 
sill to curb the 
draught. 
3. Cool moist air can
