In recent work on the bee, Mr.. T.
w. Cowan states that the insect can
draw twenty times it's own weight, can
fly more than four miles an hour, and
will seek food at a distance of four
miles. BY beautiful mechanical
adaptation its wings bear it forward or
backward, with upward, downward or
suddenly arrested course.
1t is said that large milk company
is to be formed in Denmark for the pur-
pose of giving the consumer a purer
milk than hitherto and they describe a
plan of running all their milk through
series of sponge before delivery. The
result, they tell us, out of 5000, 900 gal
Ions of milk run through, they obtain
| five tons Of filth, no doubt the result of
unclean milking.
1t is proposed to cast glass, not nee
essarily transparent, into large blocks
| for buildings This material is practi-
cally indestructible, perfectly non-ab-
sorbent, and therefore damp-proof in a
manner which few bricks are, and in
this way coarse glass of this kind could
be made nearly as cheap as concrete,
stone or baked clay.
The construction of the worlds
longest railroad is progressing rapidly
along the river valleys and across the
steppes of Siberia The western ex-
tremity of the road is the mining town
of MASK, on the eastern side of the
Ural range, and its eastern terminus is
Vladivostol1, on the Sea of Japan, max

| Two little islands furnish four ffths
of the cloves consumed by the world.
| The islands are Zanzibar and Pemba,
and little while ago Arabs found il
very profitable to bring slaves from the
African lake region to the coast and
smuggle them in the night over tx
| Pemba to work on the Glove planta
tions. These farms were very remu
nerative once, but the market has beer
overstocked and the price has fallen Sc
low that the Glove raisers have decided
to diversity their crops.
Though Brazil now produces few
diamonds and little gold, it is declared
to have a measureless wealth in iron
copper, marble, saltpeter, rock crysta
and graphite, with fair amounts o.
coal, silver, bismuth and antimony
The state of Minas Gereas is probably
the richest, for there are found gold
silver, diamonds, the beautiful red anC
green tourmalines, priced by collectors
copper, lead iron occurring partly a
magnetic, salt and graphite. Minerals
The discovery of gold in meteor
ite, which has just been made by Fed
eral Government Geologist Turner ii
California, is of unusual interest Th
meteorite in question is about the sig
of mans fist and around good por
tion of it is a solid film of gold. In on
part the metal is about an inch square
Gold has never before been found il
connection with meteoric iron, and
demonstrates, says Mr.. Turner, ''tha
there is gold in the worlds of space

Very excellent authority says: II
is fact that such fruit as the apple
the pear and the plum, taken whe
ripe without sugar, diminish the acidit

The vegetable sauce and juices are col

tend to correct acid;ty. A good rip
apple, raw, is one of the easiest of vei
