1t attributes many accidents at sea to
the fact that the lookouts are color
blind.
Prof Nothnagel, the Austrian. court
physician, traces the grip back to the
ninth century, and says it recurs with
varying intensity for three or four
years, and then dies out for twenty or
more years. As to remedies for 1t, DIR.
Nothnagel seems to be sure only OF one
thing, and that is that antipyrine should
not be resorted to.
in a steel mill at Eewburn, En-
gland, is machine that will shear an
ingot of steel thirty inches in width and
twelve inches in thickness A mighty
foot holds the ingot in place, and the
knife descends and ships off piece as
boy cuts candy. Hydraulic power is
used, and the cut can be made in about
three seconds.
The orange crop of California has
become so large that it can not be mar
keted at paying prices. Thousands OF
acres of the land of California are now
bearing young lemon trees. The olive
and fig crops of the state are now profit
abb. Experiments in the raising of
Ceylon tea in Southern California will
soon be tried.
"A blue rose is among the impossi-
bilities. There is a law governing the
coloring of flowers, which is simply

| Canada gets her share of natures
bounty to this half of the world this
year, and the bureau of industries re-
ported last week that the grain yield in
Ontario is extraordinarily large The
wheat crops, spring and fall, are esti-
mated at 3S, 5S4, ,026 bushels, nearly half
as much again as the crop of 1890 The
oat crop exceeds by 22,O0O,000 bushels
last years light crop, and the average
prairie crop is the highest in ten years.
One hundred and forty-eight thousand
fewer acres were sown in barley than
last year, but the yield is 541, 737
bushels more.
Experiments recently conducted in
the school of physiology in Paris.
France, have demonstrated beyond per-
adventure that the kernel of the oat
contains three medicinal principles, the
first of which acts to calm, soothe and
tone up the brain and nerves, the sec
ond yielding phosphorus to weakened
and hungry nerve tissues, and the third,
residing in the husk of the oat or oat'
meal, to act as a laxative and anti-con-
