Build Your Greenhouse Walls of Concrete 
Concrete costs but little more than wood and is much more satisfactory. 
A structure of concrete will not burn. It is vermin proof; it will be permanent, 
free from repairs. Concrete maintains an even temperature more easily than 
wood. Properly constructed concrete walls retain the warmth in the winter 
and are a protection against intense heat in the summer. 
When You Build Anything Build of Concrete 
Talk to your architect, contractor or material dealer about its advantages. 
If you want information about any specific point write us. We maintain 
a free service bureau to help those who want to build concrete structures.

Fences That Keep Their Alignment 
A properly built fence, one that is gal¬ 
vanized throughout and set on posts that 
stand rigidly erect under all conditions is 
an economy in the long run.

depressions, when applied so rapidly. 
With the overhead system, however, every 
square foot of soil receives its share, and 
it is applied in such a gentle spray and at 
such a slow rate that there is not the 
slightest injury to even the most delicate 
blossoms and growing plants, and it soaks 
down into the soil where it falls like a gen¬ 
tle rain, leaving the surface in the best 
of condition for subsequent cultivation. 
Also, where the rows run in the same di¬ 
rection as the nozzle lines, you can use 
the irrigation in connection with your 
work of weeding, transplanting, etc., as 
you can water a few rows at a time while 
the rest remain dry. 
There are several other important uses 
for this new system of irrigation when 
used in the garden of considerable size. 
First of these is protection from frost. 
Paradoxical as it may seem, when plants 
are covered with a coating of ice, they will 
be protected from freezing even during 
quite severe cold weather. Even such ten¬ 
der things as beans and tomatoes have 
been protected from several degrees of 
frost by being sprayed with water warmed 
up to a temperature of sixty-five degrees, 
although a thin coating of ice formed upon 
the foliage. In order to protect plants 
from frost it is necessary that the spray be 
kept in constant motion — that is, it must 
fall upon the plant at intervals of not 
more than two minutes, while the tem¬ 
perature is below freezing. If the water 
can be warmed, so much the better. On 
areas of considerable size, a simple ma- : 
chine to turn the nozzle-lines automatical¬ 
ly, at whatever rate is desired, may be pur- •' 
chased, and by this means protection can 
be given even without staying up through 
the night to attend to revolving the pipes. 
Long ago experiments proved that plant 
foods of various sorts, especially fertiliz¬ 
ers and chemicals, applied in liquid form 
were particularly effective; and insecti¬ 
cides and fungicides are now used more 
efficiently in the form of sprays than in 
any other way. Overhead irrigation may 
be utilized in applying these things with 
the least possible labor. But these are 
matters which, of course, do not interest 
the person with a small garden as much as 
they do the owner of the large estate and 
the commercial grower. 
What is the outfit, and what does it 
cost, to cover the average small garden, 
say 100 feet square? If water at a pres¬ 
sure of from twenty to sixty pounds is 
already available—and if not it will have 
to be supplied by a power pump and a line 
of pipe leading to the garden — all the 
equipment required would be: 
2 “risers” 4 ft. long, from the main 
line to the nozzle line, 8 feet of 24 
inch pipe, at 5 cents. $0.40 
2 patent unions with strainer and 
handle, galvanized. 3.60 
200 ft. % inch galvanized pipe, at 
5 cents . 10.00
