During my late visit 10 New OK, 'is''c"
the sugar.works of Messrs. Tylee & Mapes, IN
Leonard. street, which establishment has adopted
the rev process Of sugar making invented oy
Professor Mapes. BE- this process they manu'ac-
ture from 5000 TO 10000 pounds Of sugar per
day from common West India molasse=, and
generally OF a quality superior to that mace from
the cane in Louisiana. They often use moasses
which has become sour, with good effect
As an evidence Of the improvement IN making
loaCsugar, would add that by the new pro-
cess. the refining BY the AID OF clayis abandoned
This old process requires at least thIrty days 10
complete the loaf for market; whereas the IN
proved mode accompishcs the same IN SIX DAYS
thus making vast saving III time, machhe's
and room
This evaporator viii undoubtedly be belntroduced
for sat.nlaking, concentration oi extracts oi aye
woods, &c.

The choice as 10 the mode of communication
by wires placed within lcadcn pipes under gro"nd,
or through similar wires suspended IN the alr,
has occssioncd much pcrplexiiy 10 the scientific,
bnl the latter will probably be found much the
most economical IN It's first structure, as well as
in the facility of repair. The rapidity ol com

dnid masses. according TO Mr.. Wheatstone, is
$4,000 miles equal to / = times around the
cl,be) in one second. We see the "slreak' OF
LIGHTNING in the heavens, but it leaves no trace
the stream of electricity has pdssed in less than
the twnkling of an eye, and Is gone lar beyond
our sigbt. In the same manner, with equal
swiltness, the electromagnetic fluid unerrlngly
conveys the intelligence lntrusied to ITS opera
ton.
Foreigners are now claiming the merit OF the
inyeption 10 reduce the discovery TO practice;
vet history, il is believed, will hereafter accredl'
fhe hiqhest and most deserved commentator to
one Of cur countrymcn
A new field is thus laid open for the erescarches
OF science. and new dscoreflcs may yet nc eN-
uer,cd Experiments have already been made

insulated in coils with perfect success. y small
battery of 100 pairs Of plates was suiii eient for
the operation Of the whole distance. lncitectmg
the Transmission of intelligence by the telegraph
the artificial magnet, sec the paper |, above
mentioned created by electricity, sets in motion
an apparatus which gives on paper certain cha
racters, reprcscnting letters of the alphabet
Communications are thus recorded, either by day
or night on revolving cylinder, without even
superintendent, and may be transcribed at lei
sure. The mccum employed is simply copper
wire insulated and extended on posts, at an OK
pense not exceeding $3.50 per mile. 1t is conf
tienllv believed that proprietors will thus connect
their dwellings, with The places of their mcchan
cal operations. How easily, for instance, could
Boston and Lowell be thus connected? The
same posts, too, would answer for many lines OF
communication Each wire, however, must be
insulated; and, strange as ii may seem, If two
wires are placed horizontally at some distance
apart and one is charged, similar effect Will be
produced on the other.
Among the most curious effects attending this
discovery is the transmission OF intelligence
through single wire, at the same time, from oP-
positc points. Thus, on Il wire reaching from
Washington to Baltimore, message, by electric
itv, will pass another iravcrslng II contrary d.
rcc,ion, turning oct as 1t wcre,) without any de-
tention Liho tho rays of light, electricity too
is extremely subtle Nor is the fact less aston
ishing, that the ground itself Isl good conductor,
and supplies the place OF another wire, which Is
necessary in ordinary cases before any effect Is
produced.
The advantages of this mode Of communica-
ton must be obvious, both in and peace
The east and the west, the north and The SOUTH
can ENJOY the earliest intelligence of the markets
and thus be prepared against speculation. Crmi.
mails will be deferred from the commission olcrmcs
under the hope of escaping upon the iron horse;
for the mandate of Justice oulrunnng their flight
will greet their arrival al the first stopping place
The numerous inquiries respecting the telegraph
have led me to notice it with this particularly.
Intimately connected with this branch of sci.
encc empoyed in ctiecting the results obtained
bf the telegraph. are the medicinal applications
by the magnetic battery, mentioned in the report
OF one OF the examiners. This same wonderful
agcnt-ihc electromagnetic fuid-whlch also

dssolves the calculus stone IN the bladder with

doomed TO a lingering death, or the sad alierna
i've of a more cxcruciatng operation. The Ia
city with which medicines are infused into the
system by the and of this battery, leads us to hail
the approach OF a quicker alienation of human
woes, and the future success OF experiments.
iraught with the brightest anticipations.
The experiment of illuminating the streets OF

This is, indeed, it were, chalning the lightning
