NEWS'VEN.DERS' BENEVOLENT AND

PROVIDENT SOCIETY.
The thirteenth annual general meeting of the above
society was held. last night at Anderton's Hotel, Fleet-
street; James Harmer, Esq , in the chair.
Mr. COLE, the secretary,yead the annual report, which
was of a very satisfactory character, and it congratu-
lated the leembers that during the past year not a single
application had been .received for either benefit of the
society, pension, or temporary relief, by any one of its
members. The report next adverted to the eminent
services the society had received from John Forster,
Esq., who had presided at their anniversary dinner, sup-
ported as he Was by Charles Dickens, Esq., with many
other highly-gifted, literary, and influential gentlemen,
which had been crowned with• great success, producing
for the benefit of the society 1741, The committee also
had the pleasure of announcing that since the last meeting
1251. had been added to the capital of the society, making
a permanent investment in the public funds ut 1,3751.,
besides a balance in' cash of 91. 9s. The report ex-
pressed great regret that their highly-esteemed treasurer,
Mr. Merrett, had tendered his resignation in consequence
of his advanced age and infirmity rendering the duties
too burdensome to him. The report, in conclusion, in-
dulged a hope that ere many years had passed the News-
venders' Benevolent and. Provident Institution would be
considered, from its ability to relieve the distressed and
shelter the afflicted, one of the noblest ornaments of the
metropolis.
Mr. WILD moved " That the report just read be
adopted, printed, and cirenlnte& among the ,subscribers
and friends of the institution." , In support of this reso-
lution, he said that the society was going on in a very
satisfactory manner, and he might mention as a fact, that
of all the applications for temporary, relief, not one in
four came from members of the society, but from those
persons mainly wit; had been improvident in their youth
and, had laid up nothing, and made no 'revision- for the
day of trouble.
Mr. GILBERT seconded the 'resolution, and regretted
to find that they had not ye; touched the chord that
should Malec° the collateral branches, or even of the
trade itself, to subscribe to the funds of the society, as
not one out of forty of the newseendera of the metro-
polis and its vicinity were contributors in supp4t of this
institution. He did hope, therefore, that some effort.
would be made to increase the number of annual sub-
scribers, and that such plan would receive a considerable
degree of encouragement on the present occasion. As
a preliminare to' this object ho suggested that a cheap
supplernenterY annual dinner should be got up, where
even the poorest class of the trade, with the masters,
might attend to concert and organize measures for their
common welfare and benefit.
The resolatian was then put and agreed to.
Mr. TERRY Moved the next resolution :—" That the
thanks of the members are largely due and are hereby
tendered to John Forster, Esq., the chairman, and the,
stewards, for their able and zealous services at the an-
nual dinner."
The CHAIRLIA.N said he spoke from personal observa-
tion when he said that nothing could have been more
delightful then the meeting presided over by Mr. Forster,
and thought they would do him but justice in passing
that resolution.
The resolution was unanimously carried.
Mr. BROWN, • a highly-laudatory 'address, moved the
following resolution :—" That the best thanks of the
members are due, and tendered, to Mr. Merrett, for his
lung and faithful services as treasurer, with heartfelt
sympathy for the' Cause of his retirement, and sincere
hopes for his better health and future happiness."
Mr. WALTER seconded the resolution, which was
carried. ,
Mr. MERRETT returned thanks for the mark of fa--
your they had shown towards him as a humble labourer
in the cause of the society, and expressed his determi-
ration, for the remainder of his life, to uphold its inte-
rests to the utmost of his power.
Several other routine resolutions were put and agreed
to, and Mr. Terry was appointed treasurer for the en-
suing year.
A resolution of thanks was also passed to the press,
and particularly to the daily journals, for their advocacy
of the interests of this institution.
Mr. L. WILD ilea proposed a resolution to the effect
—". That the most grateful thanks of the members are
due and tendered to James Harmer, Esq., for his able
services upon tho present occasion as president, and his
great and continued liberality to its funds."
The motion was seconded by Mr. GILBERT, and car-
ried amidst much applause.
Mr. HARMER, in acknowledging the compliment, said
that he contributed to this institution because he owed
great obligation to the newsreaders. His property had
been mainly supported by them, and It would be un-
grateful in him not to support those who had supported
him.
Mr. GRAVATT moved—" That the thanks of this
meeting are greatly merited, and are hereby most cor-
dially and gratefully acknowledged, and proterreel to the
proprietors of those journals who have kindly advocated
in their columns the interest of the society."
Mr. MERRETT seconded the motion, and stated that
the vast improvement which had taken place in the con-
duct of the daily press, and the rapidity of publication,
which had been brought to such perfection by machi-
nery, had tended greatly to the profit of the newsven-
ding trade.
The resolution was carried.
The greater part of the cedinanY then retired to the
supper-room, where a very superior repast was provided;
after which the usual loyal toasts, and "Prosperity to
the Newsvesciers' Benevolent lastintionn were drunk
with great enthusiasm, and the evening terminated in a
very agreeable manner.

DRITRY-LANE THEATRE.
This establishment closed last evening for the season.
A new abeaon is talked of, but the time of commence-
ment is not known. Mr. Bunn had announced in the
bills that he would address the house, and ariebrdingly,
after the opera of Der Freischiltz, he came forward, and,
after a warm greeting, delivered the following speech,
which was received with the liveliest expressions of
mirth and approbation:—
Me. Bann said—Custom exacts that a steward
should pericelically give an account of his reckoning,
or, in Parliamentary language, that a speech should be
delivered at the wore of a session. Adopting, for one
moment, the latter position, I should naturally begin
by saying-icy Lords and Gentlemen, I can • at
length release you from further attendance here,
and I um happy to be enabled to say that you
can retire into your respective homes whenever you
think proper to do so. It airerde me great satisfaction
to assure you that I have received throughout an arda-
OU3 seseioa the most cordial co-operation froni every
maablr of my government, with one exception, end that
I continue on the most friendly relations with our allies.
Gettlemen of the louse of Commons—(addressing the
gallerits)7-I beg to inform you that, although the esti-
mates for the year were framed with a view to the
strictest economy, the receipts have not been found
Neal to the expenditure—a feet naturally occasioned
by a falling off in one important branch of revenue—
our income-tax. At the same time it must be borne in
mind that I have relieved you from very heavy taxa-
tion, as you can now come here for little more than one-
half of what you were' formerly accustomed to pay. To
descend, however, from metaphor to facts. If our at-
tempts to give English Opera in as perfect a form as
possible have not been so fully successful as could be
wished,- it is no fault of yours, who have been ready to
patroniie; neither is it, 'abstractedly, any fault of ours,
who have also been quite ready to be patronised, I -as-
sure you. Bat the extensive plans which bad been laid
down for your pleasure and our remuneration have been
thwarted by. those who were unmindful of their duty
either to one party or to the other. The eminent per-
formers attached to the theatre who have worked so loy-
ally through the season, will continue their exertions
with untiring energy; and I beg to assure you that dur-
ing the recess our best efforts shall be directed to make
the next season one of sack brilliancy as to place our
art onnhat footing so much to be desired. The ladies
and gentlemen I tilludei to have requested me to return
their grateful thanks for your unceasing kindness to
them; and for myself, I respectfully assure you that
nothing on my part shall be wanting to merit that feel-
ing which you have ever been pleased to manifest to-
wards me.
Mr. Bunn retired amidst reiterated plaudits.

`PRIDAY

ROYAL SURREY GARDENS.

Ye4terday afternoon the first flower show which has
V.k(Ji pl. ea rtt these gardens this season was exhibited
with unuEcal éclat. 42 might be expected from the
hckwarinesa of the spring, the show was almost en-
tirely confined tO grembouse plants, which, however,
were put forward in sufficient variety and beauty to more
than compepsate fcr the absvme of our usual vernal flori-
culture. Some cf the varieties of cape heaths were par-
ticularly beautiful, and attracted much attention; but
the display of azaleas 1V:43 unsurpassed by anything we
have witnessed for some time part. SOMC very gorgeous
devices in flowers, and a magnificent chow of hearts-
ease also came in for their fair share of admiration.

Though the weather towazds—tfaelaTtTpart of the
day was very threeteriing, the gardens were thronged
with a most numerous and fashionable assemblage of
ladies andA;entleinen, most of whom waited for the
finale b the evening's entertainments—the eruption of
Etna. The wholeday phsied off remarkably well.
The fellowing is a list of the -prizes awarded by the

INSTITUTION OF CIVIL ENGINEERS.
Oa Tuesday, James M. Bendel. Esq., President, in
the chair, the paper read was " Observations on Arti-
ficial Hydraulic, or Portland Cement; with an account
of the testing of the brick beam erected at the Great
Exhibition," by Mr. G. F. White, Assoc. Inst. C.E.
After detailing the experimente made by the late Sir
Isatabart Brunsl, the paper noticed the peculiarities in
the practice of toe English and foreign engineers in the
use of cements' and limes. It was -stated that in Eng-
land the,natural cements were plentiful, and the mode
c.f caastruction being eenerally in brickwork, quick set-
iag cements were pref erred ; ' whereas abroad the natural
cement stones were, coMparatively &peeking, rare, and
the use of bricks.rather the exception than the rule. In
some cases it was found, that evetathe, best natural hy-
draulic limes did not set with sufficient rapidity, in salt
water, to do away with the • necessity for using pczali,
lanes, and some of the attempts made at various periods
to substitute artificial pozzalanes for the expensive
natural products of that nature, were then described.
The unfavourable results of-these attempts, and • the
'manner in which: M. Vicat. explained them, were de-
tailed. A sketch, was then given of the course of iIiVQS.
tigation followed in England by Mr. Frost and General
Sir Charles Patley, from which it appeared, that until
the introduction of the Portland Cements, no artificial
compound bad been discovered which possessed the tam©
—or greater, powers of resistance thaw those of the
natural cements. The advantages of the Portland Ce-
meat were stated to be, thet it had nearly all the qua-
lities of rapid setting presented by the natural materials
of the same class; and in addition, that as it was capa-
ble of supporting variable proportions of hand, it could
be, used as a mortar, the rate of selling of Which might
be modified fit will,
an 4 i the polders of resistance
which were stated to be _much greater than those of
either the cements or the limes thus replaced.
A general description of the manner in which the
Portland Cement was now manufectured, and of the
methods of testing the article, were then given, and it
-appeared that after seven days the cahesive strength-of
the neat cement wes equal to about 1001bs. oh the square
inch; and that after six, months this became equal to
not leas thflTe 4 talbs. per sqaare inch. M. Vicat had
Fonts et C hause62s, that byar ttihfieciti:
stated, in 1851, in a communication to the. Mettles des
alone, er what ho termed " overhurnt lime," it would be
possible to form immense capable of re-
destroyed the natural cements, aucl the
sisting the action of the waves- and. of the shingle upon
the sea shore, ea action which it was well known rapidly
mix-
tures, whether of natural or artificial peaalle"s•
The several applications of the Portland cement as a. ,
concrete, as a mortar, and at "ie-stueco, were then alluded
to, and reference wee made to the early failures in form-
ing large artificial blocks, and an account was given of
pozzalanic
the mode now adopted in :constructing them at Dover
and Alderney harbours of
s - refuge, and likewise of those'
employed to protect the extreineties of the breakwater
of Cherbourg. At Dover the hearting of the piers',
below hightwater mark, was executed in blocks of con-
crete, composed of cement and shingle in the proportions
of 1 to 10, and occupying about three-fourths of the
volume of the separate materials measured in the dry
state. Each block Contained from 30 cubic feet to 120
cubic feet, and weighed from 2 tons to 7 tons. At Al-
ebolofopk:ttlnii Cement
Al-
derney a species of concrete composed of cement, sand,
and shingle, was placed in a mould, with rubble stone,
bedded irregularly in the mass, the proportions being
about one part of cement to ten parts of foreign mate-
rials. At Cherbourg the system adopted was to build
immense blocks of rubble masonry of not less than 712
cubic feet, and weighing abort 52 tons. These blocks
were floated out from the places where they were con-
structed, and sunk as " pierro perdue;" but this had not
on all occasions been able to resist the transporting
power of the waves. The manner of using the cement
was in the' form of mortar, composed of one part of
cement to three parts of sand.
It hard been stated bywa Ms
e.lnVinicountt,ty' thataEtixa
tiptithbeeidt;fpoonor wtohefreslcBoosnf:
resistance to compression absolutely required, in sub-
stances
expoied to the action of the sea, must be at
least equal t0'401133. 'per -Squire inch, VA of that to ten-
sion at least equal to 91bs. on the square inch. Now,
the resistance of the artificial stone blocks, after an. in-
terval of nine mouths, ty:t3 not leis than 1,700113 a per
square inch, when the effn't was one of compression, or
than 2001bs. per square inch when it became an effort of
tension, or little hitericeeto that of Portland stone itself.
Attention was called to the fact, that the Portland
Cement adhered.mare energetically to the Portland stone
than to any other material. The degree of adhesion did
not seem to depend se much upon the absorbent powers
of the substaeees connected together by the cement, as
upon some coincidence in the meaner of their crystal-
lizTlthi°6ll4plications of Portland Cement to the purposes
