THE CHAIN PUMP.

The oldest Lifting Friction Pump, acts without Valves, having
several flat solid Pistons. The top Piston which takes the weight
of the column of water, has nearly as much Friction as a Piston in
a Common Pump, the other Pistons have some Friction, and so
have the joints of the Chain Sprocket Wheel, &c. The water con-
stantly repassing the Pistons in a Chain Pump, renders it an un-
steady Machine, varying its effect according to the speed it is
worked at, and the height to which it raises the water. A better
machine for a 15 than for a 30 filet lift, because the greater the al-
titude, the faster the water repasses the Pistons. I have not seen
a Chain Pump, but from the drawings, it is, without doubt, an ex-
pensive and very precarious Machine.
Dare England assist in fairly testing this National Tax of defec-
tive lumber, against the Fountain Pump, by a mode of trial, avoid-
ing nautical tricks till after decision, upon these the most frugal
terms. If Government will eommand a best Chain Pump to be
fixed with a stage for twelve Men to stand and pump upon at Nor-

by the side of the Chain Pump, in order that both Machines may
be accurately tested against time, man for man, to the best altitudes
for the Chain Pump, as not exceeding 24 feet.
The Patentee's reward to graduate with the comparative merits
of his invention :

If the old Pump beat the new Pump, the Patentee to keep his
Machine, and hear the expense of fixing the same. If both Pumps
prove equal, the new Pump to be taken at the price of the old Pump.
But if the Fountain Pump surpass the Chain Pump one per cent.,
the Patentee to receive a bonus of 501., and the like sum for every
one per cent., when the gain is exemplified before the powers
that be.

A superior effect is all that wants demonstration in this case.
For as regards economy, simplicity, portability, conveniency, non-
liability of choaking or deranging, durability, and easy reparation,
these properties the Fountain Pump possesses in a very high degree
over the Chain Pump. And for steadiness of action, the new Fric-
tionless Pump stands alone, commonly performing, without the
slightest diminutio❑ of effect for many years, whether in raising of
water four feet or forty yards high. Thus, in a very brief space of
time, have the discerning portion of society practically annihilated
its every imaginary objection. Whilst the real defects of the old
Friction Pump have continued for thousands of years, and under
every possible modification must remain for ever.
As life or death hangs upon the efficiency of Pumps, humanity
will aid the progress of the only efficient machine. Delivering of
the water from Ships in a sinking state at sea is a work of such
vast importance, that even crowned heads would do well in excit-
ing competition for the best productions for that purpose. For
constant exhibition it would show benevolence towards their sub-
jects, and guard the poor mariner by demonstration from fatal im-
position, from which to protect the public is the duty of the world's
Obedient servant and instructor,

POSTCRIPT.

Accurate trials by manual force of the power of the old and the
new public Pumps, with the height the water was raised, and the
result reduced to one foot high, the true standard of effect :
Amongst many other men one man, weighing 133 lbs. , raised the
most water at all the Pumps, working each Pump full speed for one
minute. _ .

With one common Pump, the best out of the many upon Ayl-
sham road, he made 42 3} lbs. strokes, lift 64 feet, effect equal to
8,736 lbs. of water raised one foot, high.
With one Fountain Pump, (out of 6 from 50 to 95 feet long,
each producing similar results), upon the same road, the same man
made 34 6i lbs. strokes, lift 71 feet, effect 15,691 lbs. one foot.
With one common Pump, constructed for contest at the half
mile, London Road, he made 32 5 lbs. strokes, lift 66 feet, effect
10,560 lbs. one foot, being 5,131 lbs. less than the Fountain Pump.
The two last Pumps tried half-minute time.
The Common Pump's effect was 5,9001b5. 1 foot.
The Fountain Pump's effect was 9,0001b5. 1 foot.
Which last effect equals a barrel of water raised 25 feet high in
80 seconds. Two men at a time, working moderately, filled a 9i-
barrel water-cart in 144 minutes ; lift 71 feet.
Friction renders it impossible to produce such results by common
friction Pumps, because
With the Old Pump the water is hoed up by a leather scraper.
With the New Pump the water is weighed up by a rolling
pressure.
Pumps are made to work light or heavy, at pleasure, by keeping
two levers.
One man can raise as much water 10 feet high, as 10 men can
raise 100 feet high.
Two men prove sufficient for road-work to 50 feet high ; but if
much higher it might be better to employ throe men. The Trus-
tees may then treat the public with the luxury of sound, pleasant
turnpikes.
The wells should be made as wide as practicable—the bottom
six feet.

Doctor Young says with the best-constructed common Pump a
man can raise a hogshead of water, old wine measure, eighteen
feet high in one minute, or 9,4501b5. one foot high—but he also
remarks that in practice the quantity of water actually raised by
any machine seldom exceeds half the power consumed after over-
coming friction and leakage.
Above fifty feet high was predicted to be the common Pump's
stronghold.
Result of trials 6,o99—majority 15,691 for the Fountain Pump.
9,582 for the Common Pump, the average of the three Pumps
named in their best condition, including the Doctor's.
There ought to be many fair trials made, that the public may be
guided by facts, and not by fools.

CRITERION.
If any blustering hydraulic engineer profess much, let him show
a machine, with which a man, of less than 1401bs. weight, can
raise more than 3 imperial barrels of water, above 10 feet high, in
less than 60 seconds, if he cannot accomplish that, tell him he never
made a good machine in his life, and is ignorant of the laws of
motion—as a boy or an old woman can effect that with a Fountain
Pump.
Upon the roads named, the common Pumps for short lifts are
horridly defective and inadequate, requiring 6 to 8 minutes for two
men to raise 6 barrels of water 10 feet high, whilst with Fountain
Pumps, constructed for effect, two men can, as often as they please,
fill a 6-barrel cart in less than one minute, and raise the water to a
greater altitude.
But what is most satisfactory to the inventor, Brewers, Maltsters,
Dyers, &c., &c., insist upon it that they have not one quarter the
trouble or the expense to keep the new principle in perfect action,
that they had to keep in tolerable condition their former scrape
and go pumps.

AN IMPORTANT APPLICATION OF THE NEW

PRINCIPLE.

Mr. Shalders,
have the satisfaction to state that the pair of No. 0,3,
Fountain Pumps for steam-power were put to work last winter to
drain 2,000 acres of land, but there being 2,000 acres more upon
the same level, makes it equal to 4,000 acres. All parties interested
seem well satisfied with the result, but think it probable that in
great floods, a third pump may be required. We produce a constant
stream of water, about half a foot deep and nine feet wide, deliver-
ing 120 barrels of water per minute.
Yours, &c.
Louth, Lincolnshire. WM. ASHTON.

REMARKS BYOPPONENTS.
We knew our Common Pump had no chance with the Fountain
Pump at a short lift, but certainly should beat it at a long lift.
And even now, although there is no chance left us for a long lift,
working minute time, we certainly shall beat it by the day.
Gulp down that John Bull, and then try to swallow a Ledge
hammer.

REMARKS BY DOCTOR BIRKBECK.
The Fountain Pump is free from the liabilities and defects of
the Common Friction Pump, and approaches to a perfect hydraulic
machine.
