NEW PROCESS FOR BLEACHING RosIN-At a recent
meeting of the Liverpool Chemists, Association
Mr.. Mercer exhibited specimen of purified and
beached rosin substance, he said which at first
might not appear to be of much interest or impor-
tance; but the bleaching of rosin was a problem
which had occupied the attention of the most emf
nent chemists, and hitherto without success Now,
however, the problem had been solved, and patent
! taken out by Messrs. Pochn and Hunt, of Man
! chester, by which common black rosin, worth only
| As. Cd per cwt., converted into beautiful
white article, worth lSs. per cwt. To obtain this
result, the rosn to be purified is placed in a still
| with receiver, and steam pipe, in connection
with boiler, is introduced into and reaches to the
bottom of the still, where it radates into various
smaller pipes, perforated so to allow cf the exit
OF steam The still is heated until the rosin melts
when steam is admitted and thoroughly permeates
the entire contents the temperature of the still at
the same time being raised to 600 degrees at which
1t Is maintained until all the contents of the still
capable of being volatised have passed into the
receiver the contents of which, at the close of the
operation, will be found to consist of fluid and solid
matter-the former being principally water and
the latter the bleached rosin, holding quantity of
moisture In suspension. After the water has been
driven of by remelting, the rosin has the beauti-
1uiy whlte transparent appearance of the specimen
| on the table. DR.. Edwards (the Chairman noticed
the Importance of the matter thus communicated,
| and now that it had been made known, one was
only surprised that it had been so long undiscover-
| ed, the process was so simple. He also descanted
on the value which steam was calculated to afford

STRANGE LIFE.-John Stephens one of the MO
neers of the Wabash, died in Fountain county, Ind
a few days since, at the age of about seventy
years.
The Attiea Ledger says that in his younger days
he occupied fair position, and his future was sha-
dowed with bright prospects. He served with Col
Croghan IN defence of Fort Stephenson, against
the attack of the British and Indians in the war of
1872 for which the Government in his old age
awarded him a land warrant for one hundred and
sixty acres of land. In the meridian of life, the evil
spirit of dissipation overlook him, and from thence
forth his prospective usefulness lost A mind
that was made tit by nature to adorn almost anv
station in life, was distracted and torn into fag-
ments; and he became wild wanderer, amusing
and exciting every one with his eccentrcities and
vague imaginations. He gave himself the cogno-
men, "The Christian Philosopher of the Nineteenth
Century" which he retained for himself to the last
AFRICAN SUGAR CANE.-We have been presented
by DR.. J. F. Edwards, who resides in Chnccolocco
valley, in this county, with beautiful clear speci
men of syrup, made from the Omseana or No
African sugar cane, which is said to be better than
the Chinese. This specimen is decidedly the clear

more in the gallon has been offered for it than the
best New Orleans molasses.
He made ,402 gallons of nolasses and about 375
pounds of sugar, and has still hand or 10 bar
rels Of moasses which he is offering to sell at 80
cents per gallon

ripe by bursting at the joints. Clay land proved to
be better than bottom land
The mill, by which 500 gallons per day could be
pressed out is easily worked by one horse, and
about 3O0gallons could be boiled down in five hours.

LEAvENwORTH, X. T., Jan. 81 1889
DEAR IR: There is more of the prospects of civil
war now in the territory than there ever has been

on the other side of the river, about five miles from
this place.
He was taken with his son and the negroes into
Weston, Mo. He is there yet. Old Brown is above
here about twenty miles with fourteen negroes,
stolen from Missouri. He is surrounded. He
is well armed; got a reinforcement of thirty
men, and they were coming in from both
sides. The prospect is, there will be fight. He
captured two of our citizens and holds them. Ru-
NOR SAYS he has hung one. They are coming over
from Platte county Missouri, to rescue the negroes
and take old Brown. The Governor Of Missouri
has offered reward of SO 900 for Brown. Every
thing looks like fight
Brown will fight and he is well armed and in two
cabins Yours &c.
