A truly modern bathroom 
is a perpetual delight. 
Silent Si'wel-clo Closets 
are rapidly displacing the 
obsolete loud-flushing closets in pres¬ 
ent-day buildings—not alone because 
of the quiet operating feature but be¬ 
cause of mechanical and sanitary ex¬ 
cellence. The Si-wel-clo is but one

“Tepeco” plumbing is beautiful, prac¬ 
tical and permanent. How perma¬ 
nent can be realized only after ex¬ 
perience with other kinds. 
“Tepeco” plumbing is china or por¬ 
celain, solid and substantial. Dirt 
does not readily cling to its glistening 
white surface, nor will that surface 
be worn away by scouring. With 
time, inferior materials will lose their 
sanitary value, dirt will adhere, the 
appearance become uninviting—the 
piece lose its usefulness. 
Insist that all your plumbing fixtures 
be of “Tepeco” ware. A wise invest¬ 
ment—a beautiful one. 
If you intend to build or renovate your 
bathroom be sure to write for our in¬ 
structive book, “Bathrooms of Character."

The Ventilation of the House 
(Continued from page 33) 
cate joints of the ‘‘ventilation system.” 
Also, even when working to the best 
possible advantage, the vent system 
would not succeed in drawing air from 
rooms at any too remote a distance 
from the stack, requiring long horizontal 
pipe runs in which the friction would 
be sure to counteract the suction, and 
so prevent the air being properly moved 
out. 
How Air Moves 
Besides, foul air can not be moved 
out of the house unless adequate pro¬ 
vision is made for allowing cold fresh 
air to come in to take its place—a fact 
we often forget! Generally, our fire¬ 
places and windows provide unintended 
—but equally efficacious—opportunity 
for the replacement to take place. The 
ordinary double-hung window can gen¬ 
erally be depended upon to provide from 
three to six square inches of opening 
in the joints around the sash, which is 
a great modern aid to ventilation,— 
that is, unless the occupant of the house 
has been so careless as to spend more 
good money in counteracting this dis¬ 
pensation of Providence by putting on 
metal weather strips to save heat and 
fuel—when he may pass easily and pain¬ 
lessly “West” on any day or night 
when the gas cock falls out of the old 
fixture by the head of the bed! 
The English “casement"—opening out, 
if you please—is a great aid to ven¬ 
tilation, especially on a hot night, be¬ 
cause, if properly installed, it is always 
possible to throw out one or another 
sash so as to intercept, catch and lure 
into the room any wandering or va¬ 
grant breeze that may be at large,—a 
beneficent office that can hardly be ex¬ 
pected from any ordinary “double-hung” 
window, with its already stingy open¬ 
ing partially still further obscured by 
curtains, shades, draperies and screens. 
Only the young, agile and slender mos¬ 
quito may then pass through! 
Most old ventilation systems were 
also laid out on what has since been 
demonstrated to be false premises. They 
formerly invariably planned to take the 
air from the top of the room (to which 
the heated air within the enclosed space 
would naturally rise) without recogniz¬ 
ing that the foul air most to be avoided 
was actually at the bottom instead of 
the top of the room! Therefore, the 
most effective larger systems have de¬ 
pended on providing ducts of sufficient 
size, opening near the floor of the room, 
to permit the air at the floor to sink 
by its own weight, or gravity, to a 
central point in the lower portion of 
the house, where it can be properly 
heated and so moved on and out of the 
building, thus strengthening and con¬ 
tinuing the movement of air which is 
most normal and natural under the ex¬ 
isting circumstances. 
Yet even the most perfect systems 
of this type are so variable and unstable 
that they are affected, or altogether dis¬ 
arranged, by unimportant and generally 
unnoted incidents. The opening of a 
window or door admitting a current of 
fresh cold air, a change of wind, a sud¬ 
den drop or rise in temperature; and, 
unless immediately corrected, the re¬ 
sult of such an interruption of normal 
processes is generally to reverse the 
air current and redistribute the foul air 
that has been so collected either all over 
the house, or to concentrate and deliver 
it in one particular room or section of 
the dwelling! 
In even the modern schoolhouse, 
where ventilation systems are supposed 
to have reached their highest perfection, 
and where they are continually checked 
and controlled by delicate thermostats 
and a trained engineer is kept in con¬ 
stant attendance, the results have been 
so often unsatisfactory and disappoint¬ 
ing that there is at the present time 
serious discussion proposing discontinu¬ 
ing the use of these elaborate systems 
altogether because of the poor and un¬ 
certain returns provided for the money 
required by their installation and opera¬ 
tion. 
Heating and Ventilation 
Therefore is there all the more reason 
for avoiding such artificial and mechani¬ 
cal systems in house building; instead, 
it is safer to depend upon a properly 
arranged and balanced heating system, 
of whatever type is best adapted to the 
design and arrangement of the indi¬ 
vidual plan. To provide ample window 
surface—incidentally, the absolute ad¬ 
vantages of the English casement win¬ 
dow for results in this direction are 
not to be despised!—and, with a prop¬ 
erly arranged plan, with properly dis¬ 
posed doors, windows, fireplaces, there 
is little likelihood of a normal Ameri¬ 
can family suffering from any lack of 
proper and adequate ventilation in their 
home! 
Windows were intended to admit air, 
as well as sun—no artificial or mechani¬ 
cal means can be as certain or effective 
in the home. The heating system—with 
fireplaces, and hot air or steam—will 
also accomplish results. It remains mere¬ 
ly to give the sun a chance—by having 
plenty of windows (not only on one, 
but on three sides of all the rooms!) 
and keeping the interior decoration light 
and cheerful,—and, on occasions, over 
the gas stove, under the kitchen hood, 
or in the cellar or attic, to locate an 
electric fan near the inlet into the 
vent flue, of ample size, direct flow and 
.proper arrangement, to solve the whole 
problem of home ventilation, as we 
know it today! 
A Super-Dog With a Primitive Streak 
(Continued from page 51) 
and trained to guard sheep and run 
down criminals—both occupations call¬ 
ing for strength and aggressiveness. To 
be satisfactory in either his “profes¬ 
sional” role or that of general purpose 
companion such an animal must be un¬ 
der control at all times, otherwise his 
instincts may get himself and others 
into trouble. 
The most satisfactory police dog, 
then, is the one which has been thor¬ 
oughly trained in at least the rudi¬ 
ments of police work. Such training 
enables him to distinguish between 
friend and foe, develops his intelligence, 
makes him amenable to control, and 
gives him a purpose in life. It does not 
follow that after the training period 
actual criminal work is necessary for 
the dog to remain at his best; the mere 
experience gained under his trainer will 
give him balance and discrimination, 
like a man who has been through busi¬ 
ness life and learned hard lessons. 
There are several ways in which such 
a trained dog can be secured. You may 
buy a mature one which has already 
had his schooling; you may get a puppy, 
bring him up in the ordinary way until 
he is seven or eight months old, and 
then put him into the hands of a com¬ 
petent professional trainer; or, finally, 
you may train him yourself—if you 
are an experienced dog handler and 
have the time to devote to him. 
A properly bred, educated and kept 
police dog is one of the best guardians 
and companions a dog lover could de¬ 
sire. He is a sort of super-dog, a power-
