Device to Protect Plants from Frost
Now Excluded from CONNER
ciaI Purposes by
Any One

Alexander G. McAdie has done what
is extremely exceptional in the world
of patents and inventions. Usually an
inventor patents a device for his own
use and enrichment. In the present
case, the inventor has obtained a pat
ent on a plant protector and mas dedl-
Gated the invention to the public. He
obtained a patent so as to be sure tnat
no one else could ever monopollze the
device and thus defraud the pubic OIL
the rights which he intended to bestoW'
The public is now practically the owner
of the patent. The device is composed
of two layers of waterproof transpar-
ent paper separated by laths or other
strips of wood. The paper is supported
on small posts above the plant ped'
forming an efficient protection from the
sun and keeping in the heat waves
which come from the warm ground ana
are of paramount importance IN the
raising of tender plants. The ar space
between the layers of paper prevents -
the frost from injuring the plants as II
practically insulates the air below from
the outer atmosphere.
This action of Mr.. McAdie's mas
given to the public a highly useful m
vention. At the present time there Is
advertised a special glass panel for not
houses which utilizes this same primer
ple. But this paper device answers
quite as well, and better, for the aver
age gardener, and relieves MN lroIi
the necessity of paying royalty;
Engines adapted for use in Tying
machines are still occupying the at
tention of numerous inventors. George
Dorffel has invented an eight-cyl1nder
engine of the same general type as the
one used by Paulhan in his successtul
Farman machine. This new engine
looks light and strong, being symmet-
rically built so as to Withstand hlgIl
