--lO0,OOO young shad were recently
shipped 10 Germany. where they are TO be
placed in the river Rhine, under the direc-
ton of the Deutche Fischerie-verein.
The steamship Tagus recently took
out as a portion of her cargo ten powerful
locomotives Of American manufacture.
She Is bound for Taganerud, Russia. at he
extreme northern point ofthe Sea Of Azon.
The locomotives We're ordered some
months ago for Russian railway. a
considerable quantity of shot and she'll,
belonging to the Turkish Government also
went forward by the Tagus, and will be
discharged at Constantinople.
The lemon cropis poor this year along
the coasts Of Spain, Africa and Italy, which
usually furnish the supplies. Mentone. on
the Mediterranean, below Nice, in the
south of France, has fine crop, however.
and the fruit from there bears sea voyage
much better than any other kind. There
is now AN unusual number of American
vessels in the harbor of Mentone. The
average cargo for a vessel Is 5000 boxes.
each containing 800 lemons. This would
make the number of lemons carried by Il
vessel about 2,500OOO.
The Gold Hill Mine, in Colorado,
promises 10 equal i'm richness its famous
firSt-ciass ore from il have been found TO
be amazingly rich. One lot of ore. for ex-
amtle. which was assayed. yielded 72O
ounces ofgold and 2.3i0 ounces of silver To
the ton. Another lot assayed yielded
2.233 ounces of gold and 9,2l6 ounces of
silver. or total of S62. 526. 10 per ton. San
born Il Sanford took out OF this mine late
ly 800 pounds OF ore which will average -
10 the pound.
The United States raises annually about
l50.000,000 bushels of potatoes. represent
ing money value of about 100000. 600.
Twenty-Five per cent. of the potato j. solid
dry substance. and Of this sixty-two and
five-tenths per cent. il starch. One hun
dred and fifty bushels of potatoes. which
NAV be- raised as easily as twenty bushels
of wheat. contains 1850 pounds of dry nu-
tritive substance. The tweaty bushels OF
wheat would contain only l.0H pounds of
dry substance. of which sixty per cent. is
starch. and a. starch j. the material in liv-
ing bodies which furnishes nutrition 10 the
respiratory processes and fat TO the tissues.
for these purposes "A crop of potatoes is
worth double a crop of wheat.
The following plan for the prevention
of the bursting of water pipes during frosty
weather has been invented in England. Ii
j. well known that when water freezes it
expands. and that the force exerted is so
enormous that no pipe can stand il. This
invention is intended 10 give the water a
chance 10 expand without bursting fhe
pipe. Ii attempts this by securing in the
inside Of the metal pipe a space equal to
the difference of volume between water
and ice. so that when the water freezes 1t
occupies the space reserved for il, instead
Of exerfino its force on the nine and hurst
ing ii. This is practically carried out by
passing through the water pipe small
India rubber tube, specially made for the
purpose. and of such a diameter that the
space inside il is little more than equal
10 the increase i'm volume of the ice. The
India rubber tube Is always kept full of air.
so that when the water freezes IL finds the
necessary space for expansion, for by COM
pressing the air tube ii displaces the air
and takes its place. When the ice melts the
tube again expands. becomes filled with
air. and is ready for another frost. and so
on for any number of times without re-
quirng attention.
