pal in this educational drama was seen 
turning slowly. Was it irritated by the 
light, and would it crawl from the lines 
of focus? This would mean much labor 
in moving the heavy apparatus in what 
seemed a fruitless and costly experiment. 
But its uneasiness was caused by the saucy 
taunts of the decoys. Its wings were ele¬ 
vated slightly. It could not resist answer¬ 
ing some of those rasping calls. The man 
behind the searchlight could be seen glis¬ 
tening with perspiration as he “fed” the 
carbons of the great arc light. The writ¬ 
er’s fingers were upon the switch of the 
camera motor. Then the insect’s wings 
began to rhythmically move and another 
chant was added to the chorus of “katy¬ 
did, katy-didn’t.” So it continued until the 
picture was taken. And this picture has 
been seen by thousands of school children 
who previously never knew how the in¬ 
sects “sing.” 
Sun-Hot Water Day and Night 
M ODERN building methods have 
made forward strides within re¬ 
cent years to the extent that now house¬ 
holders in ordinary circumstances may en¬ 
joy the privilege of hot water day and 
night without resorting to the expenditure 
of a penny for fuel. 
The solar heater is man’s and woman’s 
humble servant in sections of the country 
where the sun shines at least every other 
day in the year. The principle of solar 
heating has been developed so scientifically 
that it is now possible for a family to have 
hot water which will range from 115 de¬ 
grees in the daytime to 100 degrees or 
more at night, without going to the trouble 
and expense of installing, firing and taking 
care of a water heater. Old Sol does the 
work. 
A man who just recently built a new 
bungalow in southern California has one 
of the most efficient solar heaters to be 
seen in the country. He had the system 
built for him, but the man who is handy 
with tools and pipe wrenches can build his 
own solar heater or else get a plumber to 
make it and install it. The expense is not 
great. The Californian in question got a 
forty-gallon solar heater, with a forty- 
gallon reserve tank for $117.50. Needless 
to say, he is satisfied with his investment. 
The principle of his solar heater is sim¬ 
ple. A large sheet of copper has 150 feet 
of three-quarter-inch galvanized water 
pipe coiled backward and forward across 
its surface in such a manner as to make 
certain the absorption of the very last 
heat unit that the sunshine throws upon 
the coils. The coils of pipe are soldered 
to the copper plate. The plate with the 
coils upon it is placed in an airtight box, 
similar to a window frame, and covered 
with a heavy piece of glass. 
Ordinarily a solar heater is mounted 
upon the roof of the house in such a way

A SON’S thoughtfulness gives the old homestead the 'protection as 
well as the conveniences afforded by modern science. The Pyrene 
fire extinguisher, recognized as the most efficient weapon against 
incipient fires — easy to operate and instantly effective — is as great a 
necessity as the telephone. It is always at hand, to use when the blaze 
starts - — long before any outside aid could be summoned, even by the tel¬ 
ephone. Will you risk the danger of a fire tragedy in the old home by 
denying it this protection? 
Ready for use, and is easily refilled. Promptly extinguishes vicious gasolene, 
oil and electrical fires. Does not injure most delicate fabrics. Write our nearest
