American watches are fast driving
Swiss watches out of the market Our
factories make 50, 900 watches week.
There are more bee hives in the
United States. where there are $780,
O00 than in any other country. Greece
famous for its love of honey, has only
80, 900 hives.
Canon Bagot stated at the British
dairy farmers conference that 81, 1,O00,-
900 had been expended in the erection
of butter factories in Ireland, and that
factory in Limerick receives 30, 900
gallons of millS daily.

culture. They are in the aiority in
the cotton, linen and jute industries.
and in the silk trade there are 117,000
women employed, and but 17,TOo men.

The photographic bureau at Wash
ington for two years has been trying to
learn something of the characteristics
of the Atlantic ocean as u great moving
body of water by bottles. AS a result
the whole Atlantic is shown to be cir
culating round and round like an enor-
nous pool.
1t is claimed to be possible to DEM
onstrate differences in the colors of ink
which cannot be seen, the one ink ap-
pearing light and the other dark. 1t is
well understood the tints of the inks
that are called black are either brown,
red, green or blue in shade; such tones
have but little effect on the eye, as it is
chiefly sensitive to the yellow and red
rays.
The bladdcrworts are wonderful
things in the ponds just now. The
plants float upon the surface of the
water by means of countless little bags
| full of air, joined to the seaweed-lil5e
leaves The ripe seed falls to the bot
tom, takes root and grows there in soil.
When the Towering time arrives, the
bladders fill with air, buoy the plant
upwards, dragging it, roots and ALL to
the surface, in order that the flower
may breathe air and sunshine.
The want of sufficient strength to
Withstand the pressure resulting in
boiler explosions is n fact to which con-
siderable attention has recently been
directed, and, although it is admitted
| bp Of fGtr ,rrfh l,a la,.
ent in the original construction, the
opinion is expressed that it is most fre-
| quently the effect of weakening of
the iron by strains due to unequal ex-
pansion; the cause of such unequal ex-
| pansion, and also of weakening by
burning and blistering the iron, is
usually the presence of deposit or scale
on the heating surface.
The railway mileage of Canada has
| just about doubled in the past ten
years. In 1881 there were 1850 miles
of railway in the Dominion, and last
year there We're 14,OOO. The earnings
last year We're S4S, 192, ,O90, and the ex-
| penses S34, 800, 449 The Canadian Pa
cific earned slS,672, ia, of which 81, 1884,
O4O was net The Grand Trunk earned
| S17, ,423, $50, of which 81, S02, 3S1 was net.
| Commenting on these figures one prom
| incnt Canadian newspaper congratu-
lates the country, but regrets that q
| satisfactory growth of settlement has
not followed the extension of the rail-
way system, and points out that there
is much room for improve ment on that
especial point.
"A new and convenient protective
| for small abrasions of the skin is sug-
gested by an English chemist. 1t is
prepared by mixing equal parts by
weight of camphor and absolute alco-
hol, and dissolving gun cotton in this
solution in the proportion of one part
to forty. When applied to the skin it
rapidly dries and yields an elastic film
which is an excellent substitute for
ordinary collodion. Itreadily dissolves
salicylic acid, carbolic acid, iodoform
and many other medicaments intended
for external application. AS con-
venient protective it is likely to super
sede sticking plaster, as the skin film
formed is not unsightly, does not pre-
sent awkward corners liable to catch,
| and is not washed off even when moder~
ately warm water is used. Healing of
small abrasions rapidly follows the ap-
plication of this solution, either alone
or when mixed with small quantity of
| salicylic acid.
