few weeks more, should no obstacles occur,
VIII serve to open the entire route to Wor-
cester. Between tide water and the Albion
factory, nine granite locks, of most substan-
tai masonry were passed. Just before en-
tering SCOTS pond: a beautiful basin of
deep water, there are three continuous
locks, by which you ascend an elevation of
twenty-four feet. The novelty of ascend
ing and descending from the different lev
els, was particularly gratifying to those who
had never before witnessed this operation,
The boat glides into solid granite box. if
we may so speak, in which she is enclosed
by the shutting of folding gates. The wa
ter is then admitted through wickets in the
upper gates, and the boat is rapidly raised
to the level she is to ascend the upper
gates are then opened and she passes on.
In descending, the water is let out of the
lock, after the boat is enclosed in it. and she
is depressed to the level below. This ou
Grafton occupied, in passing up, about four
minutes, and in descending was performed
at several OF the locks, with a delay of but
three minutes. The average height of the
locks is about ten feet.
The boat returned to Providence abou,
seven o'clock amid large concourse of
spectators who had assembled to greet her
arrival A more gratifying excursion could
not have been enjoyed.
IMPURE AIR The following letter of DR.
Webster, on the the subject of purifying the
atmosphere, is worthy of attention. 1t may be
particularly useful to those who have the mis-
fortune to have sickness in their families this
warm weather. The odour often found in sick
rooms so unpleasant and unwholesome both TO
the patient and attendants, it will be seen, NAV
be removed, and the air purified, by cheap
and simple process. The means of such relief
to the afflicted ought not to be neglected. We
should suppose that all physicians would fur
nlsh themselves with the necessary drugs" so
as to accommodate their patients whenever
there is occasion for it,

MIR. HALE,-Although the means of prevent
ing and destroying putrid or infectious miasma-
ia, by the use of chemical agents, has been long
known, they have been resorted to for the most
part only on accession of alarm They may be
health at this season, that venture to send YOU
a brief notice of preventive and remedial
agent, which may be employed in any situation,
and under all circumstances
Within few months, great use has been
MADE IN France of chemical compound of
chlorne gas and lime or soda, for the purpose
OF destroying the offensive odors arising from
purifying animal and vegetable matter. The
flrst use OF this compound was in case of Judi
cial inquiry, where it became necessary to dis
inter body for examination, and by it the efflu-
VIA were destroyed in an hour or two
For all common purposes, the effects of the
compound of lime and chlorine, known in COM
merce as bleaching POWDER and ''bleachng
salts, are similar to those of the substance used
IN France under the name of " Labannaque's
Oisinfecting Soda Liquid
Ihe bleaching powder may be sprinkIed about
an apartment, or small quantity thrown into a
vessel which it is desirable to purify; or it NAV
De dissolved IN water, and clothes be Dipped in
the solution, and afterwards be BROUGHT into
the vtlated atmosphere. Vehicles for the re-
moVal OF offensive substances, as well as the
substances themselves, may be freed from all
offensive odour by the use of the powder, while
at tne same time the fertilizing powers of those
substances are remarkably increased fact
which has been established by actual expert
ment
In some situations and apartments, few
spoontuls OF the powder may be mixed with
the sand with which the floors are usually sprin-
kled. The many occasions, both in public and
private, where this purifying agent may be ad-
vantageously employed, must be obvious. It
is sometimes desirable to prevent the rapid
change of dead body previous to interment
this would be accomplished by small quanti-
ty OF the dry powder within the coffin, or bv
the application of the moistened clothes
In descending into vaults, pits, sewers. &c,
IT the air breathed be passed through sponge
which has been wet with the solution, the per
son can remain some time without injury in
situations where others not so provided would
intallibly be destroyed.
The use Of this substance in the sick cham
Der will be found source of no slight comfort.
and even safety i'll some diseases; and it has
been applied to ulcers and putrescent sores with
manifest advantage.
The effect'of this chemical agent is not like
that Of vinegar, and the various substances re.
sorted to on occasions like the above, it does
no1mereiy disguise the odour, it chemically
encompasses and destroys it. 1t is perfectly in
nocent and not expensive, unless purchased in
the small quantities usually sold in small tin
boxes; it should be obtained from the manufac-
turer or importer, by the pound.
