NMI PUMPS.

TO A CROWN.
SHALDER'S FOUNTAIN PUMPS.
4 The most powerful in the world, with which a man of
4 st°fle weight can raise an imperial barrel of water forty-
i three feet high in a minute. but with no other Pump yet tried
o a minute and a-half. Their practical gain is most extraor-
narY, seldom below 70, and mote frequently above 100 per
f„n,t, taking the average of the results of every altitude from
Pot to lota feet high. This remarkable gain in the art of
t4'linlg waterlg was effected in the simplest manner possible,
i merely by substituting a rolling instead of a sliding prin-
i4e for Pumps, by which their friction and leakage was
ad, after the tens of thousands of bootless attempts that had
been made by the ablest mechanics in the world for 2,000 years.
int °r a long time after this immortal invention was publicly
r°duced, a host of bullying novices insulted society by pre-
n!ting that it would prove limited and frail, who are now
i;.,l„vellii,g about that their trade would be ruined, because

indeed, the art of raising water approached perfection 4,000

ltt.t. The Chain-pump in action is direct and simple ; but by
on and leakage very defective and dreadfully uncertain,
and from its numerous parts highly complicated. The Chain-
Pulp is a combination of inefficient expensive lumber—a
united 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.
This is the root and principle of all Piston and Cylinder
,P,nmps, under every name and modification. All Pumps upon
'441 plan are of necessity bad beyond remedy, and stupid indeed
'kilt thee be who expect the contrary, because mostly above
ttwo-fifths of the labour employed is entirely wasted by their
otetion 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.
4t4, and last, Shalder's Pump appeared and made laughing

the other three Pumps, and exalted tl.e art of raising
water to a science. The Fountain Pump is neither more nor

And although, from its diminished friction it has its advantages

New Plan, with mechanical parts alike, and so adjusted that a

barrels fifteen feet, one barrel fifty feet, and nine imperial gallons
