"A fine specimen Of the egg Of
Epyornis, the extinct giant bird OF
Madagascar, and obtained from south
ern Madagascar, was exhibited at re-
cent meeting of the Geological society
of London. 1t will be remembered that
this egg is about 10 inches long, and OF
the capacity of $50 hens eggs
-"If pound of coal is subjected toa
dry distillation and the products and
residuals treated chemically by the
processes for obtaining the well-known
coal tar colors," says the Age OF Steel,
of st. Louis, 1.-The one pound so treated
will yield enough magenta to color 500
Yards of flannel, vermilion for 1850
Yards, aurine for 100 yards and aliza-
rine sufficient for 155 yards OF red
CLOTH"
1t is estimated that there are $780,
0OO, ZOO, 900 feet of available lumber
standing in the forests of the state OF
Washington. This is an average OF Is, 900
feet for every acre Of land in the state.
Many thousands of feet of cedar lum-
Der are now being shipped from Wash
ipgton to what a few years ago was the
heart of the Wisconsin pine region.
The sack-sewing gage thrown down
by Pendleton, Or, man a few days
| ago, on basis of his sewing up 600
ffty-pound bags in five hours is taken
up by a sack-sewer in Portland -four
mill The latter has record, SO it is
claimed, of weighing, sewing, and
trucking away 159 fifty pound sacks in
one hour, and 10 hundred-pound sacks
in the same time One thousand one
| hundred to 1900 sacks in ten hours is
| said to be the average in Portland
mills.
| An expedition is proposed to locate
the north magnetic pole. the point Sc
lec:ed for investigations being King
Williams Land. 1t is desired to dis
cover the law that governs the con-
stantly occurring changes In magnetic
declination, inclination and intensity,
SO that these variations may be calcu-
lated for future periods as eclipses are.
1t will also be sought to establish
whether the so-called pole was fixed OF
moving at the point where the needle
assumes the vertical position.
| If the Pacific could be laid bare, we
should have q most singular spectacle.
There would be number of mountains
with truncated tops scattered over 1t,
and those mountains would have an ap
pearance just the very reverse OF that
presented by the mountains we see or
shore. You know that the mountains
on the shore are covered with vegeta
ton at their bases, while their tops are
barren or covered with snow; but thest
mountains would be perfectly bare a.
their bases, and all round their top'
they would be covered with beautiful
vegetation of coral polypes.
Herr Weismann. distinguishes
German biologist, has pointed out tina
the average duration of the life OF bird
is by no means we'll known Small
singing birds live from eight to eighteen
years Ravens have lived one hundret
years and parrots still longer in cap
tivity. Fowls live from ten to twent,
years The wild goose lives over on
hundred years, and swans are said =
hsve attained the age of three hundred
The long life Of birds has been regarded
} as compensation for their lack of fertil
ity and the great mortality of thei
young.
A specimen Of soft, bituminous Goa
from the Argentine Republic of Soutl
America has been analysed by Kyle
and found to contain the element vana
drum, principally in the condition Q
vanadic pentoxidc, each ton Of coal cor
, tanning about four pounds OF the pur'
, pcntoxide. Aside from the scientii
interest of the occurrence of this rar
, metal in coal deposit. it will undoub'
{ cdly prove a valuable and cheap sourc
> of supply of a substance which is 81
{ tensivcly used in dye works.
France has 1000, 900 head of cattl
which yield daily 1900, 600 gallons {
r milk, worth s23S, 0OO 600 annually. TIL
Flemish. Norman and Breton breeds {
, cattle give the most milk. The mil
trade of Paris is almost entirely in th
9 hands of few important companie
the milk is guaranteed free from adu
iteration and is sold in bottles of glas
4 stone ware and porcelain. The lare
: quantity of milk used is partly OWN
to the milk cure prescribed by man
French physicians and also to the nj
