A European engineer has invented
and brought to perfection an instrument
by which he can readily locate water
underneath the earth's surface. At a
late trial in this country, he surprised
our engineers by correctly tracing sew
eral a%qurductS of whose location he

Compressed carbonic acid gas Is now
used on ship-board for freezing meat,
brine being cooled by the expanding
gas and circulated in pipes. On u
steamer which carried 80, 900
of mutton to Liverpool from South
America, the meat was kept in excel
lent condition, with a saving of four
fifths of the former coal consumption
for working the refrigerating machin-
cry.
Nearly 1000 miles of railways are
under construction in France, of which
bou 800 miles are expected to be
opened in 1891. This is Il good showing
for France, but it looks insignificant
compared with the construction record

their feet are disproportionately large.
Even the masculine foot of to-day Is
smaller than that Of the ancients, but
the feet of women show IL greater re-
striction in size as n result of cramped
shooting. To the artistic eye, the sym

Clay which is pure white, and that

washed to bring it to II uniform shade

applying it to the surface of the pieces
Of paper, and then polishing it by means
of brushes driven bv machinery.
The ARCHAEOLOGICAL Institute Of
Vienna has been conducting expert
ments on dirt taken from finger nails,
and s~eventy-eight examinations lave
beer made. The process was to put the
dirt in '~'cultivating mixtures" such as
are used for supplying germs with food
on which to develop. The crop that
grew from the germs in the dirt was a
varied one, and included thirty-siX kinds
of micrococci, eighteen of bacilli and
many others.
Professor Henderson, who accom-
panied the late exploring expedition to
the Olympic Mountains, and who is a
recognized authority on the flowers Of
the Pacific coast. gives some interesting
data of the trip to the Portland Oregon

flowers in the Olympics at an altitude of
10, 900 feet that would be found in
Alaska on the ocean level. vas very
