simply turn the faucet any time and steaming water instantly 
flows. Close the faucet and the gas is automatically turned 
off. The complete story of Hoffman convenience, comfort 
and economy is told in this gift book which you may have if 
you send the coupon. Hundreds of men and women are read¬ 
ing it —to their profit. In justice to your own home, send for a

which cuts the water into drops like rain. 
The machine rotates in a circle, the dis¬ 
tance covered being regulated by the 
pressure. Another rotary with two 
nozzles delivers fan-shaped sprays which 
evenly and properly cover a 75' circle, 
besides being capable of several special 
adjustments. 
While devices of this kind cannot be 
substituted for the more permanent sys¬ 
tems for use in the vegetable garden 
and large flower gardens, they are espe¬ 
cially valuable for lawns and for use on 
small garden plots, where larger systems 
are not needed. 
All these systems are so simple that 
no special directions are required for 
their use. Yet it is well to remember 
that the best time to apply water is late 
in the afternoon or on dull days, as 
there is much more evaporation when 
the sun is shining brightly. Likewise, 
it is just as important to cultivate the 
ground after an artificial rain as when 
the water actually descends from the 
skies, for moisture escapes from the 
soil very rapidly unless the crust is 
broken up and a dust mulch created. 
TINTED LIGHT 
T HE human race evolved through 
thousands of years of adaptation 
to natural daylight. This white 
light is suitable for the utilitarian re¬ 
quirements of plant and animal life but 
it is not generally satisfactory from an 
esthetic viewpoint in interiors. Let us 
speculate for a moment upon the rea¬ 
son for this. 
Many thousand years ago, when 
primitive beings made the wondrous 
discovery of fire, the corner-stone of 
civilization was laid. The application 
of fire and artificial light by those early 
primitives has given the greatest impetus 
to civilized progress. They warmed 
themselves, cooked their food, and de¬ 
veloped simple industrial processes. 
They carried fire to their caves, and 
chill and darkness fled. Their clammy 
dens were converted into homes by the 
introduction of comfort, cheerfulness, 
and protection which fire and arti¬ 
ficial light provided. This happened 
many centuries ago, but from the view¬ 
point of evolution of the human being, 
it was only yesterday. In other words, 
the human race has just come indoors. 
Throughout the centuries which have 
intervened mankind continued to burn 
material in the production of artificial 
light. Wood, fat, oil, and gas were 
consumed by fire to provide light. 
These flames were an unsaturated yel¬ 
low in tint. They radiated warmth 
and cheerfulness, and through untold 
centuries of association with the home 
their characteristics have become deeply 
rooted into the psychological status of 
the human race. 
A century ago organized science at¬ 
tacked the problem of light-production. 
Increasing the efficiency of light-sources 
was its slogan and as a consequence 
real advancement began. The gas-man¬ 
tle, the arc-lamp, and the incandes¬ 
cent filament lamps appeared. These 
have been great boons to human prog¬ 
ress and they have represented in gen¬ 
eral great strides from the tint of the 
flame of burning material, toward the 
whiteness of sunlight. They supply the 
HERBACEOUS 
utilitarian needs of the human race 
much more effectively than the more 
primitive flames, but these develop¬ 
ments appeared so suddenly and so 
recently as to leave mankind still ad¬ 
miring and desiring the cheerfulness 
and warmth of tint of the flame as a 
light-source for the home. 
The relatively high efficiency and 
great convenience of modern light- 
sources which serve so well in com¬ 
merce and industry can be taken ad¬ 
vantage of by the lighting artist. He 
can tint these sources to suit the 
esthetic requirements of the home. 
Thus an electric incandescent lamp 
may be tinted so that its resultant 
light matches that of the candle-flame 
or of burning fuel. This has been done 
on a large scale in the case of the so- 
called “flame-tinted” lamps. But the 
lighting artist may be guided by the 
scientist who has determined that light 
to live with must not depart widely in 
color from the natural scale of hot 
bodies. Lights of various tints have 
many applications in the vast field of 
artificial lighting, but these applica¬ 
tions are relatively few in comparison 
with those of the unsaturated yellow 
lights of the natural-temperature scale. 
The flame-tint is of the latter class. 
Thus, in this brief analysis we have 
attempted to present a glimpse of the 
evolution of artificial light in relation 
to civilized man. The flames which 
have been the torches of progress 
throughout untold centuries were aban¬ 
doned yesterday for the modern light- 
sources which work wonders in utilitarian 
fields. Today we have altered these 
highly efficient sources by the applica¬ 
tion of scientifically correct coloring 
media so that the resultant tone 
matches the color of the light of com¬ 
mon flames. Thus, today, science has 
given back to mankind in much im¬ 
proved form that which it took away 
yesterday, and we again have flame- 
tinted light which is so effective in 
making a house homelike.

W ITHIN recent years there 
has been a great awakening 
of interest in the plants which 
our grandmothers used to cultivate in 
their old-fashioned gardens. These 
plants, commonly called herbaceous 
perennials, include such familiar flowers 
as the peony, phlox, iris, larkspur, 
Michaelmas daisy, day lily, columbine, 
rocket, anemone and spirea. With a 
little care these will live from year to 
year, although the tops die back to 
the ground each year. 
Perennials are valuable because: 
1. They vary greatly in habit and 
growth and in shape, size and color of 
the flowers. 
2. Some can be found suited to any 
condition, whether it be wet, dry, 
sunny or shady. 
3. By careful selection, continuous 
bloom may be had from early spring 
until late fall. 
4. In general, they are comparatively 
cheap, propogate easily, increase rapidly 
and are permanent. 
5. Nearly all are good for cut 
flowers. 
Some plants, such as peonies and day 
lilies, may be planted as specimens in
