This Company has been formed for paving the Metropolis
'tint twenty miles round, with wood. Specimens of the prin-
ciple have been laid down at Whitehall, Buckingham Palace,
and:part of Oxford-street, between Wells-street and Newman-
street, which have proved its superiority over every other mode
e Wood pavement hitherto adopted. From authentic returns,
it appears the paving-rates in the Metropolis alone amount to
40a0,0001. annually—the repairs in Oxford.street are 5,0001.
P r annum.
.The economy of wood paving on this principle, compared
with: every other mode, ensures to this Company an ample
remuneration per square yard; and, that their operations may
be carried to any extent, it is only necessary to state that the
1144 in the Metropolis now paved with stone and Mac-
adamised comprise between ire and six millions of
Pare yards, for which there is no doubt wood will be sub-
144"ed, removing, an it effectually does, so many long-
cateplained-of nuisances. The wear and tear of wood pave
*tent, on this principle, is imperceptible ; and as the Company
contract to keep their pavement in repair, it is expected
that; on a moderate calculation, the Company will derive, out
of the large amount now paid for repairs, a net revenue of
00 0 per annum. The present orders received by the
',RlPay amount to 20,0004 Negotiations are pending for
other_ work to a great extent.
'Models and reports as to tne merits of the invention, by sur-
veyors and other competent persons, may be seen at the offices
the Company as above.

To the Directors of the Metropolitan Patent Wood Pavement

Company.
Gentlemen—As Surveyor to the Commissioners for Paving
the Regent's-park, Regent-street, and Whitehall districts, by
whose order the wood pavement on the above principle has been
mid down at Whitehall, and in reply to your note requesting my
minion of its merits, I have to inform you that the work has not
"1Y given me and the Commissioners entire satisfaction, but has
excited the admiration of )( public generally. I have no
doubt but this mode of pavement will be universally adopted,
as it is not only free from noise and mud, but the wear and tear
of public and other conveyances will be greatly reduced. The
*God pavement laid down at Whiteliall stands firmly, and is in
good condition as the first slay it was laid down.
I am, Sir, your obedient servant,
J. TOOGOOD.

T. the Directers of the Metropolitan Patent Wood Pavement

Company.
Gentlemen,—ln reply to your application to me for a certi-
ficate of my opinion of the Wood Pavement laid down by your
bearing
in various parts of London, I have much pleasure in
"caring testimony to its evenness of surface, as well as to its
compactness and solidity, and I am sure when it comes to be
generally adopted, the wear and tear of horses and carriages
I'lll be greatly reduced. As Manager of the London Convey-
:nee Company, who are Proprietors of Omnibuses, running be-
ween the Nightingale Tavern, and Elephant and Castle, I
"eve remarked that the draft is less for horses, when going over
Your experimental pavement at Whitehall ; and I think the
!line sort of paving would be found much superior to all others
In stable stalls and yards.
Hoping to see it generally adopted,
I remain, Gentlemen, your most obedient servant,
ROBERT BLORE,
Manager to the " Lindon Conveyance Company."

PUMPS.
NORWICH AGAINST ALL ENGL AND, TEN POUNDS

TO A CROWN.
SHALDER'S FOUNTAIN PUMPS.
The most powerful in the world, with which a man of
stone weight can raise an imperial barrel of water forty-
!Ores feet high in a minute, but with no other Pump yet tried
to a minute and a-half. Their practical gain is most extraor-
,24rY, seldom below 70, and more frequently above 100 per
foot tto 109 akin th
feete averhigh. age of
This the
remarkable gain results of every al

tude from
i
suingbe water was effected in the simplest manner possible,
ei being merely by substituting a rolling instead of a sliding prio-
r for Pumps, by which their friction and leakage was abo-
e ed) after the tens of thousands of bootless attempts that had
'been made by the ablest mechanics in the world for 2,000 years.
For O. long time after this immortal invention was publicly
ty.'troduced, a host of bullying novices insulted society by pre-
dicting that it would prove limited and frail, who are now
tt,uvelli!l about that their trade would be ruined, because
reintaing Pumps prove 300 per cent the most durable, whe-
-r used by the power of man, horse, or steam, and they are
7economical and invariable in their action, that they com-
'on 1/ perform for maltsters, brewers, and dyers for years with-
out
kthaebilyeast expense or the slightest variation. Also, so re-
penters, Stscim. ple, that smiths, millwrights, wheelwrights, car-
, as well as hydraulic engineers, successfully un-
dertake their fixing and reparation. neither are fountain
Pumps retarded, choked, nor injured by occasionally delivering
▪ few tons °f sand, although a very little of that material soon
eraeges and serious damages the best Friction Pumps. Slowly
indeed, the art of raisin water approached perfection 4,000
years ago. The beautiful Miss Rebecca brought up water from
▪ ‘l4ll in a pitcher upon her shoulder for her sweetheart's
camels.

Since then appeared the four principles, namely, two limited,
and two unlimited principles--two of them sliding principles,
one a spiral principle, and one a rolling principle.
14. The Chain-pump in action is direct and simple ; but by
friction and leakage very defective and dreadfully uncertain,
and from its numerous parts highly complicated. The Chain-
t.'P is a. combination of inefficient expensive lumber—a
'led sliding principle.
24. Archimedes' Screw-pump is founded upon a brilliant
idea;
butits applicability is very confined—a limited spiral
Principle.
3d. Tcsibies' Pipe and Poker Pump, or the Athenian Squirt.
This is the root and principle of all Piston and Cylinder
Pumps, under every name and modification. All Pumps upea
this plan are of necessity bad beyond remedy, and stupid indeed
Must tb.y be %she expect the- contrary, because mostly above
two-fifths of the labour employed is entirely wasted by their
friction and leakage, and when accurately tested against the
new principle, always prove to be but contemptible machines.
Nevertheless these imperfect Pumps stood unrivalled for the
last 2,000 years—an unlimited sliding principle.
4th and last, Shalder's Pump appeared and made laughing
stocks of the other three Pumps, and exalted the art of raising
,Water to a science. The Fountain Pump is neither more nor
less than the Pump made absolute, because without any dis-
coverable defect or imperfection, it possesses every essential
Property for the purpose intended in the highest degree.
AN UNLIMITED ROLLING PRINCIPLE.
Dr. Birkbeck. President of the Mechanics' Institution, Lon-
-4", sell the Fountain Pump is free from the liabilities and
defects of the common Friction Pump, and approaches a perfect
Hydraulic Machine.
- The Vice-President, Professor John Millington, Esq.,
S., published a work in IMO, and therein makes a rash,
false, foul, and silly assertion, that the new principle is limited,
and although, f-om its diminished friction it has its advantages
,11 wail cases, it cannot be used for great elevations. Never-
theless Fountain Pumps prove equally durable for lifts above as
elow one hundred feet. Millington might surely have known
that flexibility was no proof of frailty, nor rigidity of durability.
The rigid teeth of mamrra and her four sisters were mostly
tie, but their flexible tongues remained in full activity when
.r
ages, united with their only brother, exceeded five hun-
dred d years. And the Connectors or (flexible Cones) in Foun-
Pumps prove also not only surpassing durable, but almost
indestructable.

CASES SUFFICIENT.
Thirty Fountain Pumps, that cost above I ,0001., have net cost
per year for all the connectors, though twenty-four of them,
'rum. fifteen ter one hundred feet long, are used to water the
Public: roads from Wymandham to Aylsham, and at Yarmouth.
A Treble-acting Fountain Pump at Diss brewery (horse
Realer), the connectors lasted five years, lift one hundred feet.
1.11. It is the packing that scrapes up the water in the old
tk"np that wears out. And it is the connector that rolls up
e water in the New Pump that wears out.
Mark the next two cases, both Pumps having done the same
work.
A

- Single-acting Fountain P at Messrs. Horton's, dys,
Nerve (manual power). Hereutro the connectors of the New
Lump last four times as long as did the paAting of the old
limp it superseded.
A Double-acting Fountain Pump at Messrs. Stark's, dyers,
Norwich (steam power). Here also the packing of their old
Treble-acting Pump (superseded) used to last about three
months, new the connectors of their new pump last above six-
teen months. This noble machine has not cost ss. a year for
connectors, though constantly at work, and delivers eight im-
perial harrels of water per minute, PRACTICALLY PROV-
ING THAT IN SKILFUL HANDS THE NEW PRIN-
CIPLE IS DECIDEDLY THE MOST DURABLE.
The Seven Road Fountain Pumps, fixed early is 1838, be-
tween Norwich and Aylsham, have not cost a shilling, nor
varied in effect.
The Ten Friction Pumps (alias Pumplings) mixed with
them, have often been repaired, and the other day not one of
them would answer the helm—so much for comparative frailty.
