ON LAND

the New Portable Fire-engines are of infinitely better service than a
fire brigade. They act instantaneously at the outbreak of a fire.
" We are delighted with the invention—it is a great boon to so-
ciety."—Editors Liverpool Mail.
The New Portable Fire-engines have preserved a large portion of
Norwich from destruction, fur out of eighteen different properties on
fire in and near the city, they saved eleven solely and seven mainly,
including in the seven the Queen's Cavalry Barracks ; and in the
eleven, Messrs. Horton's dyery, and 12,0001. worth of consigned pro-
perty; stoke mustard, starch, and flour mills, and Messrs. Butcher's
grocery warehouses, just in time to prevent a large quantity of gun-
powder therein from exploding, which must have spread around de-
struction and death.
" North Walsham.—At this fire the Portable Engine was of great
service, and by having one of then: ready, there is no doubt but half
the property now destroyed might have been saeed."—Norfolk Chro-
nicle, August 22, 1846.
At a Norwich fire June 2, 12147, the two Portable Engines were
the pets of the public. The cry was, feed the little engines and they
will do the work, which proved true. The four large engines present
proved useless.
Portable Engines speedily prove steam-boilers to a doaen atmo-
spheres.
Now the fact is this, nll former Force Pumps, Lift-force Pumps,
Lift Pumps, and Chain Pumps are bad machines: they rub, grub, and
scrape the water upwards by friction. which wastes two-fifths of the
power used, and progressively falter b; leakage, which Drs. Young
and Hatton, with many other eminent experimenters, lamented
thus :—The quantity of water actually raised by any machine seldom
exceet-s half the power consumed, after overcoming friction and
leakage; and notwithetandlng the best engineers in the world had
tried in vain liar two thousand years to abate these palpable defects
in hydraulic machines, nevertheless, at last the victory is won, and
WOn for ever ; for friction and leakage are now both annihilated by
the new rolling principle in pumps, and their effect augmented from
twelve to twenty (or about seventy per cent.), and frequently with-
out more outlay.
Most men can sustain heavy rapid pump trials for 40 seconds, hut
some men drop at minute time. With a best new heavy working Fric-
tion Pump an aclive sound-winded young man of 140 lbs. weight can
raise 10,4100 lbs. of water one Vast high in a minute, and with a Folltl-
lain Pump 9,000 lbs. in half it minute. Thus a continual and most
extraordinary lucrative advantage is gained over perpetual and uni-
versal ignorance, clearly proving that Knowledge is Power.
John Clenton Roberts, Esq., in his popular work, No. 1,110, did
well in placing Gosset's French Pump Abortion (that slaps the water
upward) side by side with the Fountain l'etnp, which upset a good
deal of Folly. Because Mr. Mallet(, Dublin, a thorough-bred pump-
maker, Mr. Raddley, London, an everlasting pump-writer, and Mr.
Ewbank, America, an ignorant pump book-maiter, asserted that the
two pumps were identical. But the Tankee out-fooled John Bull
and Paddy in No. 1,183, and in No. 456, hook-maker Millington's
remarks are preposterous. However, on the other hand, Dr. Birk-
beck, Aberdour, Hay, Parkington, with many other discerning men,
after witnessing the perfect effect and the beautiful simplicity of the
rolling principle, gave the invention the following true sad susta'n-
able character:—The Fountain Pump is the most !mew: tent improve-
ment in the art of raising water that has appeared ,eithin the last two
thousand years—the greatest advancement in the useful arts in

modern times.
The Consummation Fountain Pumps are successfully carried out
for private and public uses, at lifts below and above 100 feet altitude,
for man, horse, and steam power; delivering from half a pint per
stroke to 100 barrels of water per minute, and rendering every fair
trial at competition ridiculous, whilst their durability is guaranteed
at less cost than commor. pumps.

COLLEGE OF PRECEPTORS.—Yesterday the half
yearly examination of candidates for the certificates in
connexion with the institution commenced at the Col-
legiate Schools of St. Peter, Eaton-square. A large
number of gentlemen presented themselves for examina-
tion, the subjects being classics, mathematics, the ele-
ments of commerce, natural philosophy, modern lan-
guages, &c. The Rev. J. Hind, M.A, was appointed
si.nior moderator, and Mr. Eccleston, 8.A., of Tricky
College, Dublin, Head Master of the Sutton Coldfield
Grammar School, junior moderator. The classical
examiners for the present session are the Rev. R. Wil-
son, D.D., of St john's College, Cambridge, the Rev.
R. G. Latham, M.D., and Mr. Eccleston, B.A. Exa-
miners in mathematics, the Rev. J. Hind, M.A., Mr.
Sylvester, M.A., and Mr. Boole. In the elements of
corktnerce, Mr. Payne (Leatherhead), Mr. Seggings
(Sudbury), and Mr. Lane (Plymouth). Examiners in
the other branches have also been appointed.
ORNAMENTAL ROOFING TlLES.—During the past
week two vessels, the Celerity and Joage Johanna, have
arrived from Belgium freighted with ornamental rooting
tiles. They are of a blue or slate colour, and cost, as we
understand, about the same as slating. One pattern in
form resembles a leaf, and would, when placed upon a
roof, have a picturesque effect. The use of these tiles
appears to be extending. We recently noticed that they
were used for the church at Staplefield, Sussex. St.
Paul's Church, Hull (Mr. Dykes, architect), has also
been roofed with them, as well as the boat-house on the
Serpentine, in Hyde-park.—Builder.
TIIE..RAJA OF SARAWAR.—His Highness the Raja
of Sarawak, after a visit at Holkham, the hospitable
mansion of our noble Lord-Lieutenant, the Earl of Lei-
cester (where he was accompanied by the Hon. Captain
Keppel), is expected on Saturday at the Palace at Nor-
wich, on a visit to the Lord Bishop of the diocese.—
