The reason kettles sing is a very sim

Young long-leaf pines, according to
Mr.. Pinchot of the Department of Agri-
culture, protect themselves against for
est fires in a most Interesting and re-
markable manner. For four or five
years the stems of the infant trees at
tain height of only as many inches
above the soil During this time their
bark is extraordinarily thick, and that
alone gives some protection. But in
addition, the long needles spring I'D
above the stem, and then bend over on
all sides "in green cascade which
falls to the ground in a circle about the
Seeding" This green barrier can with
difficulty be made to burn, while the
shade that it casts prevents infamma-
BILE grass from growing near the pro-
tected stem. Mr.. Pinchot thinks that it
is owing to this peculiar system of self
protection which the pine seedlings
have developed that the growth of ever
green oaks in Florida has been restrict
ed in regions where fires have ragged
while our pine forests have taken their
place.
