OF these persons 40 less than 2161

1899 of them being in the country.
Mr.T. r. G.. Z. Peek states that
there are important differences in the
composition OF The hot springs OF lee
land and of New Zealand. Tile hot
mud wells of Iceland contain so much
copper that several companies have
been formed TO them commercially;
while the New Zealand mud springs
are so full of infusoria that in times of
famine the natives sustain life On
diet consisting chiefly of mud.
"IlIe seiective power OF roots" says
Mr., Robert Brown IN paper upon the
food of plants, sis In reality the prin-
airy cause why nations spread natural
ly over the world. They must have
land to cultivate their crops and be-
fore artificial methods ofrenewing the
fertility of the soil were discovered, it
got exhausted or worn out and the
agricultural people had to seek newer
lands, WHICH as yet lay in all their
virgin richness"

Scotland is 4406 feet above sea-level,
and is much higher than any other

Two elevated weather stations~-that
of Pixies Peak being II, l5l feet high,
anu that OF Mt. Washington G2S6 feet
while France claims four, ranging
rom 1899 20 II, 1873 teeT; and Italy has
three of which the highest is 1886, and
the lowest is 1857 feet. Russia has
one as high as 1851 feet and SWitZer-
Ianl maintains one at a hight of 1905
