♦ SELF-ACTING FLUSHING MACHINE.

Mr. SALTER, engineer, submitted to the inspection of the
oourt models of a self acing penstock and a sett acting sluice
gate, which he invented for flu.hing sewers and house drains
without the assistance of manual labour. They appeared to
be simple in construction, and the originator described the
principal advantages of the invention to be,—the carrying off
of all sewage matter in the least possible time after its pro-
duction; less risk of the various mutters discharged into the
Sewell ff ing deleterious gesso, and of those gases
escaping into the upper atmosphere and into inhabited
planes ; a thorough purification of the house drains ; a bitter
ventilation of the sewers in proportion to the greater fre-
quency of the flushing process, every rush of water preduc-
, ing a corresponding rush of air in the direction of the outlet;
• saving of all the expense attendant cu the employment of
men to flush the sewers, and to open and shut the imperfect
flied-gates that are now in use ; and the application of the
invention to all the flushing gates which are now in opera-
tion in the sewers.

The inventor stated that he presented the article to the
court with a six months' character, a self-acting flushing
gate having been in successful operation in the large sewer
running through St. Odes's since last September.
ST. PAUL'S CHURCHYARD.

Mr. BARBER, of the firm of Barber, House, and Mead,
of St. Paul's Churchyard, presented a petition from several
of t'.e, most eminent houses in toe vicinity of St. Paul's,
praying that certain projected improvements by the removal
of the rails round the cathedral should be carried oat.

Mr. PRITCHA.RD (the high bailiff of Southwark) was
heard In favour of the proposition. He contended that the
opening of the western front of the churchyard would be of
great benefit to the public, of insinediete advantage to the
whole of the parties in trade in the neighbourhood, and
highly important to the citizens in general, especially as
improvements were about to be adopted elsewhere by the
corporation.
Mr. BARBER said he had received from all his ntigh-
boors :he most encouraging tokens of support and assistance,
and he bad no doubt of the ready consent of the ecelesiss.
Coal authorities. (Hear, heir.) He then moved the follow-
ing fl 00. ution :
Tnat it is the opinion of this court that the public con-
venience 'maid be promoted, and the architecture' beauty of
the western end of the cathedral church, St. Paul's, would
be much better displayed if the dwarf wall and railing round
the enclosed vacant area of ground in front thereof were
removed, and the space paved with flag stones, in manner
similar to that at the western end of the Royal Exchange."
Sir P. LAURIE seconded the motion, and esprcsell a
hope that the whole improvement would be effected be for,
the mei exhibition of 1841, in order that the multitude of
foreigners who would visit Ecgland in that year might see
the noble cathedral without being annoyed by the existing
impediments.
Mr. liters and Mr. Deputy HICKS spoke in favour el
the motion. Mr. Deputy Lurr idea approved of it, hut
thought it wruhl he advisable to take steps to preserve the
cathedral by a railing put far back from the line of the exist-
ing palisade.
Mr. BARBER having stated that the suggestion of Mr.
Lott w uld be adopted, the motion was carried unanimously,
end a deputation to wait upon the Archbishop of Canterbury
and the Bishop of London on the subject we immediately
appointed.
