The air OF furnace-heated rooms has
been shown by K. Dec. Ward to be
drler than that Of many desert regions
The mean relative humidity Of the room
tested was 30 per cent for three weeks
in November, and the mean relative hui
nudity In the open air for the same
time was II per cent. The lowest open
air annual mean known in the United
States is 42.9 per cent. for Yuma, Ariz.,
that for Santa Fe, \. NJ, being AS per
cent. A mean of % per cent was found
for FIVE summer months in Death VAL

A French writer for La Nature pos
sesses a dog which. having been bori
without hind legs, has, Of its own &C
cord, learned to walk and even TO ruI
rapidly on its two front legs. 1t main
tains itself in its upright position witt
perfect ease, turning, stopping, stand
ing at rest, eating its food and perform
ing all ordinary acts with its hint
quarters poised above its head, as CON
pletely master of its equilibrium, say
its owner, as a man is. Once in abOu
fifteen minutes, on the average, it rest
its hind quarters on the ground, or, b.
preference, on some slightly elevate
object. 1t is not more fatigued b
exercise than an ordinary dog.
A muddy river betokens one Of tn
greatest Of national losses. 1t mean
that the rich soil, which Jack Frost an
other natural agencies have bee
ages in forming, is washing ava
into the ocean. Tillers of Ii
p land could do much TO prevent the los

cultivated field on a slant which washt
away most rapidly. 1t is contrary
, public policy, or at least to the welfai
: Of the future, that the top soil Of sue
4 land should be sent down to the Ocea
u when it might be yielding grass crop
Many rivers that are now muddy wei
clear before the coming to this cont
nent of civilized man.
Many persons have erroneous n
