INHABITANTS OF PITCAIRN'S ISLAND.

The following list of the families and names of indivi—
duals composing the singular community inhabiting Pa--
CAIRN'S ISLAND, on the 24. h April, 1723, is given in the.
lost number of the Asiatic- Journal. We extract it, not
only as being curious in itself, but for the remarkable sup-
ivort which it affords to the proposition of Mr. MA trims,
that population, sclera unchecked, goes on doublingsitself
glary 2.5 years. The interesting account of the past
history anti existing condition of th se settlers, was pub-
lished io England a few yrais back, and will be found in
that Joni-nal (vol. ix. p SO by the way, we would re-
commend this miniature sot amen of the patriarchal state
to the especit attention of Mr. OwEir. It would afford a
line OA] for the Lozenos CJ-OFFMATIvi SOCIETY; their
principles might there have full play. We would recoils-
end them to try their experiments in Pitcairn's stew
little 1A1,74/, and when they have succeeded there, in realis-
ing their scheme of equality, then they may make this the
theatre of their operations—but not before.

It' hence appears- that the population-had been increace
by nine persons since 1819, when it consisted of forty-fir
men, women and children. At the period of Sir Treomse

1311'.1iOr ED 'STEAM ENGINE.

The following account of the new steam•engine, invented
in the United Stan a by Mr. Babcock, is copied from a
New England paper, the Providence Patrint, and is by far
the most complete and scientific description that has yet
been published:—
. " l'he invention of Mr. Babcock, which will probably
supersede the necessity of a boiler to the steam engine,
consists merely in converting water into steam at the
instant it is wanted, by allowing it to come in contact
with hot iron. To effect this, two generators are used,
formed of iron tubes, cast in lengths of three and a half feet
of five inches internal diameter, and extinct) and a half thick;
these are made to traverse n furnace heritontally,in two rows,
and are fourteen in number; the lower seven are connect d
with each other by caps, anda steam pipe leads from the
end of the last one into ha lower part of the cylinder of
a high pressure engine; the upper seven are connected
in the same manner, and a steam pipe leads from them
into the upper part cf the lame cylinder. At the
other end of each generator, anti on the opposite aide of
the furnace, is attached a small forcing pump, two and
a half inches in diameter, and about eight inches in length.
On the top of the furnace is a small copper reservoir, con-
taining a few gallons of water with a tulac leading from
each side of it, which connects it with the vamps. The fur-
nace has two fireaplaces, the eene above, the other blow,
the tubes—its eitreme outside lengthis eight feet—its
height and width, each three and a half feet. The pumps
are worked by long levers, attached to the :roes head, so
arranged as to move them alternately, and they can be
made to inject front a half to four cubic inches of water st
once, the whole of which, after performing Its duty in the
cylinder, is saved by a condenser. To set the engine
in motion a fire is kindled in the futhace, and when
the generators are sufficiently heated, an injection is
made, by hand, with one of the 'penny: (we will eappose
into the lower generater) ; the water. is instantly converted
into steam—a valve is opened to admit it into the lower
part of the cylinder, and the piston is driven up ; an in-
jection is then made by the other pump into the other
generator—a valve is opened in the top of the cylinder and
the piston is driven down. The engine then without
further assistance continues to operate with unabated
vigour and with perfect equality. The injection made
into the generator, now in operation, is at most but four
cubic inches ; the cylinder of the engine, to which they
are attached, is ten inches in diameter ; the length of the
stroke of the piston is three and a half feet, and it is cal-
culated to be a ten horse power, though it varies in pro-
portion to the quantity of water injected. The principle
upon which the generators are constructed is an evident
one; but the heretofore insurmountable obstacle has been,
that they cooled so fast, by the constant Injection
of the water, that the requisite steam power could
not be obtained by them: this is now completely over-
come by using two generators instead of one, and having
the injection pumpti so arranged as to work alternately,
that while the water is forced into one generator, the other
has time to regain, it.: expended caloric ; and here consists
the great merit of the invention ; and the merit is the
greater, because, though so simple, it has been entirely
overlooked. We have been ourselves repeatedly witnesses
of tide perfect success of the operation, and the generators,
so far from being cooled, are with ease and celerity made
to acquire the requisite degree of temperature, even when
the engine has cottnnenced working with theta at a low
temperature.
" The economy of the substitution consists not only in
space rind weight, but in both wood and water. (lad they
not succeeded in the engine to which the were attached, it
would have been necossaty to have supped their place by
a boiler, twenty-two feet, at least, in longth ; the sa.iiie
of force and weight is, therefore, three-fourths of n hat it
would have been on the cid plan ; and instead of a cord of
wooderhieh would have been consumed in four hours, there
is now nerd but two feet in the same space of time—the
saving in wood is, therefore, three-fourths ; and last, but
most important, instead of a condensed mask of scalding
vapour constantly threateLing death and destruction,
there is now used lint the small quantity of steam that
can he generated from four cubic inches of water—and
the simplest, the chkapestaind the mcutpowerful, but hereto-
fore dreaded, high pressure engine is made perfectly sate
in its use and occupation. We do not say tuft it is ahso-
lutely impossible for the generators to burst, but were they
to do so, no person could be injured unless by a piece pro-
jected from it, and then ro carelessly must they have been
constructed, that a jury of the country could hardly help
convicting their maker of premeditated manslauallter. As
the public are apt to judge of the success-of an esperiment
more from appearances than examination, we are sorry that
the boat did not move with the velocity that was antici-
pated—but [lee fact is, that the mire was intended to
move paddles of but 1.2 feet in diameter, 4*(2(1 of which,
by an alteration in the boat, it became neettaary to substi-
tute paddles of fifteen feet; as it is. they revolv:: seventeen

that byttirt applying the invention to the prupelling of a
vessel, the most difficult method has been chosen of testing
its pewer ; and yet, with the nactilir °blocks it his had
to encounter, we are assured not a doubt can exist with
regard to it in the mind of any one et all conversant with
the matter. We believe another era is about to take place
in steam machinery, that will rank the nal): of Itaeeek
