TO A CROWN.
rs--1.1-IALDEII.'S FOUNTAIN PUMPS.
The most powerful in the world, with which a man of
ten stone weight can raise an imperial barrel of water forty-
three feet high in a minute, but with no other Pump yet tried
Laaiottte and a-half. Their practical gain is most extraor-
-s"narYt seldom below 70, and mole frequently above 100 per
cent,
takint, the average of the results of every altitude from
foot to 100 feet high.- This remarkable gain in the art of
raising water was effected in the simplest manner possible,
being merely by substituting a rolling instead of a sliding prin-
Fiple for Pumps, by which their friction and leakage was abo-
lished, after the tens of thousands of bootless attempts that had
been made by the ablest mechanics in the world for 2,000 years.
For a long time after this immortal invention was publicly
introduced, a host of bullying novices insulted society by pre-
dicting that it would prove limited and frail, who are now
tiivellicg about that their trade would be ruined, because
Fountain Pumps prove 300 per cent the most durable, whe-
ther used by the power of man, horse, or steam, and they are
so economical and invariable in their action, that they com-
monly perform for maltsters, brewers, and dyers for years with-
out the least expense or the slightest variation. Also, so re-
markably simple, that smiths, millwrights, wheelwrights, car-
penters, &c., as well as hydraulic engineers, successfully un-
dertake their fixing and reparation, neither are Fountain
Pumps retarded, choked, nor injured by occasionally delivering
deranges
few tons of sand, although a very little of that material soon
reranges and seriously damages the best Friction Pumps. Slowly
'Weed, the art of raising water approached perfection 4,000
years ago. The beautiful ;Miss Rebecca brought up water from
a Kell in a pitcher upon her shuulder for her sweetheart's
camels.

-Since then appeared the four principles namely, two limited,
and
‘two unlimited principles—two of them sliding principles, a
one spiral principle, and one a rolling principle.
Ist. 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-
PuTp is a combination of inefficient expensive lumber—a
iimited sliding principle.
2d. Archimedes' Screw-pump is founded upon a brilliant
idea; but its applicability is very confined—a limited spiral
principle.
3d. Tesibies' Pipe and Poker Pump, or the Athenian Squirt.
'_!'his is the root and principle of all Piston and Cylinder
Pumps, under every name and modification. All Pumps upon
this plan are of necessity bad beyond remedy, and stupid indeed
must they be who 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 skiing principle.
4tli, and last Shalder's Pump appeared and made laughing
sistocl;iof the other three Pumps, and exalted the art of raising
vvatet. 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-
don, says 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.,
false,
.1“ S., published a work in 1830, and therein makes a rash,
f°4l, and silly assertion, that the new principle is limited,
aNI although, from its diminished friction it has its advantages
to Borne cases, it cannot he used for great elevations. Never-
theless, Fountain Pumps prove equally durable for lifts above as
below one hundred feet. Millington might surely have known
that flexibility was noproof of frailty, nor rigidity of durability.
The rigid teeth of mamma and her four sisters were mostly
gone, but their flexible tongues remained in full activity when
their ages, united with their only brother, exceeded five hun-
aired years. And the Connectors or (flexible Cones) in Foun-
tain Pumps prove also not only surpassing durable, but almost
indestructible.

CASES SUFFICIENT.
Thirty Fountain Pumps, that cost above 1,0001., have not cost
2/ per year for all the connectors, though twenty-four of them,
from fifteen to 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
power), the connectors lasted five years, lift one hundred feet.
N.B. It is the packing that scrapes up the water in the old
Pump that wears out. And it is the connector that rolls Up
the water in the New Pump that wears out.
Mark the next two cases, both Pumps having done the same
work.
A Single-acting Fountain Pump at Messrs. Horton's, dyers,
Norwich (manual power). Here the connectors of the New
Pump last four times as long as did the pa king of the old
Pump 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, now the connectors of their new pump last above six-
teen months. This noble machine has not cost Bs. a year for
connectors, though constantly at work, and delivers eight im-
perial barrels of water per minute, PRACTICALLY PROV-
ING THAT IN SKILFUL HANDS' THE NEW PRIN-
CIPLE IS DECIDEDLY TIIE MOST DURABLE.
The Seven Road Fountain Pumps, fixed early in 1838, be-
tween Norwich and Aylsham, have not cost a shilling, nor
varied in effect.
The Ten Feiction 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.
