An ice company at Dallas, lex,
proposes to manufacture $50 tons daily.
"A factory for extracting the juice of
palmetto berries has been established
at New Smyrna, Fla.
The Good Luck mine, in New Mex
leo, was first located less than six
months ago, and in the last three
months has produced $4,000 worth Of
ore, and during that time there has not
been more than five men at work on an
average,
Several attempts have been made
to establish the tack industry in the
South, but they have failed from diff
culties in handling the material This
branch Of the iron trade is in the hands
of New England manufacturers, and is
practically confined to Massachusetts.
1t has been understood that the
curcGlio beetle, which is so destructive
to the plum, produces two broods year.
Prof. G. P. Gillette has now demon
strated that, in Iowa at least, it pro-
duces but a single brood. The young
found late in the season are from be-
lated females. A parasite insect, Sig
akphUs c1trcukOnis follows the insect, and
preys on them in considerable numbers;
but with no appreciable aid to the plum
cultivator.
Masters of vessels can not be re-
minded too often of the use of oil in
stormy weather. Its importance is we'll
illustrated by facts now referred to at
length in standard books on seamanshsp p
and the International Marine Confer
ence at Washington recommended that
"the several governments require all
their sea going vessels to carry suffi-
cient quantity of animal or vegetable
oil, for the purpose of calming the sea
in rough weather, together with suita-
BILE means for applying it Pilot Chart.
The different theat-conducting powers
of metals may be easily realized by
holding rod of silver in one hand and
one end of rod of iron in another, and
| on placing the opposite ends in fire,
the fact is soon perceived that there is a
| great difference in the heat conductiyity
of the two metals. The following table
shows the relative conducting power Of
the principal metals: Silver, 100; copper
"A; gold, 53; brass, "a; tin, Is; iron, 70
lead, 9; platinum, s; German silver,
bismuth, 2.
-Evolutionists have got so far in
their studies as often to indicate with
confidence the origin of certain gener;
as we'll as species. The celebrated
French botanist, Baillon, has recently
pointed out that Hottonta, well-know1
aquatic genus of Primulaceous plants, il
certainly derived from the true prim
rose or Primula, and that the generi
changes were brought about purely b,
some one species of PqimuEG learning t,
live in marshy places, and thus assum
ing aquatic habits.
I'm the course of archaeological ex
plorations lately carried on in tn,
Crimea, Prof Vasselovski found painte,
human bones in two graves-six skele
tons in one grave and one in another
Prof. Grempler, of Breslau, is of opinion
that these graves belonged to the origi
nal inhabitants of the Crimea, the Gin
merians of Herodotus. They laid thei
dead on elevated spots, so that the bird
might consume the flesh. When quit
bleachod, the skeletons were paintet
with some mineral pigment Severa
graves containing such painted skele
tons have been found in Central Asia
Only three had been previously foun
in the Crimea.
The twenty-eighth annual report c
the government cinchona plantation an
factory in British Sikkim has bee
issued. At the end of the fnanciaIyea
1sS9-9O the plantation consisted G
1852, 4O1 trees of various ages, and of
nursery stock amounting to 2640O
seedlings. The crop collected durin
the year amounted to 304, 7O5 pound.
The products of the factory were /, 1881
pounds of sulphate of quinine, and 6, 81
pounds of febrifuge. The whole of tn
quinine and the greater part of the fet
rifuge were manufactured by the me-
fusel-oil process, and as the arrange
ments for working this process wer
quite completed during the year, th
old aeid-and-alkah method Of manufat
ture has now been definitely abandoned
