THE LIVERPOOL STANDARD

no suspicion till then, for he did not doubt but that it
was right, but he had then his suspicions. He had often
lent money to his neighbours, whether voters of St.
Anne's Ward or not, without the slightest regard to
political creed.

The Commissioner drew Mr. Parker's attention to the
statement of Brownbill about going to the treasurer.
Mr. Patker said that no such words had been used, and
that he should have given him the money imcnediately,out
of his but that he had not a stamp with him at
the time.

The Commissioner remarked that Brownbill had not,
when he was first before him, nor on that day, made
mention of the letter of distress. Brownbill, on this, ac-
knowledged that Mr. Parker's statement relative to the
letter was true.

The Commissioner said he should give judgment in the
case when be entered the court on Tuesday morning.
There would be no occasion for Mr. Parker to attend--
his clerk would do.

Mr. Bradley, the Chairman of the Radical Committee
for St. Anne's Ward, wished to make a statement to the
Commissioner respecting the political motives which were
perceptible in the case.
Mr. Parker hoped he should be permitted to reply.
The Commissioner said he could hear nothing of, the
sort.

Mr. Parker.—Certainly not : the request is as contempt-
ible as the man.
The parties then left the court.

CORRESPONDENCE.

SHIP-BUILDING.

TO THE EDITOR OF THE LIVERPOOL STANDARD

SIR.,—My only motive in writing the few remarks on
experimental shipbuilding is with the view of stimulating
those who are more immediately connected with the branch
to think and act for themselves, and not grant any theo-
retic change, (even if laid down through the most specious
arguments, or forcible appeals to prejudice or passion,)
without first practically proving the benefit likely to result
therefrom. It is from want of this research that has caused
so many speculative errors. It may be said by many that
they arc not adequate to the task, not being sufficiently
conversant with figures; this should not discourage the
aspirant, bur let him know that there is not one useful
problem in mathematics that cannot practically be solved.
In my last was shown a correct method for finding the
centres of gravity and displacement ; it is well known
there are few problems more difficult to encounter than
that of measuring mathematically the displacement ef a
ship, yet a method now about to be shown is equally exact,
and may with ease be put into practice. Having procured
the model of the vessel, from the load line to the keel, as
shown in my last letter, when the vessel built from the
drawing is launched and equipped, with all her stores on
board, mark on her stem and stern post her exact draught
of water; suppose it to be one foot above her second wa-
ter line, those heights carefully set up on the sheer plan
of the drawing, through which run a line as her light
draught of water, which line will show one quarter of an
inch above the second water line ; run off this line, as a
water line in the body and half-breadth plans ; take a
piece of the same fir of which your model was made, plane
it to a quarter of an inch thick, being the space of the new
water line, on which set down the stations and half-
breadths, as already shown; being now filled and placed
on the upper edge of the second water line, add thereto
the parts of the stem and stern post ; take from the lower
side of the third piece of the model as much as was added
to the second piece, that the model may be a perfect repre-
sentation of the vessel built,, from her load line to the
keel : thus having completed the model, add thereto
the half thickness of the rother, as high as the load water
line. Take a part of the same board which composes the
model (great care must be observed in selecting the wood
for this purpose, that every part applied may be taken
from the same board), plane it up very exact to one inch
thick, and two inches in breadth, from which cut very
nicely nine pieces of six inches long each, six pieces of
three inches long each, six pieces of two inches long each,
four pieces of one inch long each, and four pieces of half-
an-inch long each ; one of those last cut into halves, quar-
ters, half-quarters, and eighths. Suppose the vessel's
register 260 tons old measurement, her drawing being on
a quarter scale; as such the half-model, with the blocks
as above, are the same ; therefore the first nine pieces, be-
ing six inches long each, contain 6912 cube quarter of
inches ; the second. being six pieces of three inches long
each, contains 2304; the third, six pieces of two inches
long each, contains 1536 cube quarter of inches; the
fourth, four pieces of one inch long each, contain 512 cube
quarter inches ; and the last four pieces, of ha:f an inch
long each, contain 188 cube quarter of inches; to prove
the correctness of these blocks, weigh them in a pair of
scales one against the others; when complete, the whole
wilt amount to 11,452 cube quarter of inches. Take that
part of the model forming her light load down, place it
in one scale, against which place in the other blocks to
produce an even balance, say three of six inches long each,
one of three inches long. one of two inches long, one of
half an inch long, with two single quarter of inches; their
contents will show, that the half-model, to her light wa-
ter mark, will weigh 3010 cube quarter inches, which di-
vided by 35 (being the quantity of cube feet of water in a
ton), will produce 86, which mul'iply by two, as each side
gives 172 tons, as the weight of the hull and furniture.
Next weigh the part that forms the third water line, whose
even balance say produces 1715 cube quarter inches ; this
divided by 35, makes 49 tons ; twice, for both sides, shoves
that it will take 98 tons to bring the ship down to her third
water line. In like manner place the part which composes
the fourth water line into the scale, and balance it with
blocks ; say it takes 2590 cube quarter inches, being equal
to 74 tons, twice of which, for both sides, is 148; adding
thereto 98, shows that it will take 246 tons to bring the
ship down to her fourth water lice. Again place the part
which forms the load line in one scale, with blocks in the
other, whose supposed balance say is 3045 cube quarter
inches; this divide by 35, the produce will be 87 tons,
twice of which, for both sides, gives 174 ; add to this 246,
thereby showing that it will take 420 tons of cargo to bring
the ship down to her load water line. No method can be
more correct, if the ship correspond with the drawing and
model, every part of whose materials and blocks are from
the same piece of wood. The water, or level lines, may be
divided, and the model made to correspond, by keeping a
memorandum of the ship's displacement in tons, at the
height of each line; by marking those heights on the stem
and sternpost of the ship, the exact weight on board may
be known at any line of immersion. Again, should the
draughtsman require to know what the ship will really
carry, form the model and prepare the blocks, weigh the
model, and cast her register tonnage, as the old measure..
ment—(the nicest calculation that has been given for a
British-built ship's displacement, when ready for sea
with a swept hold, has been two-thirds of her register ton-
nage.) Example : your drawing being for a ship of 2tio
tons, two-thirds say is 172 toils; place the half-model,
formed from the water line, down, ir.cludine the half-
sternpost, and rother, in one scale, with the'halance of
blocks in the other, amounting to 10360 cube quarter
inches; dividing this by 35 shows that half of the ship's
displacement is equal to 296 tons; deduct 86 tons, being
half the weight of the ship and furniture, shows that it
will take 420 tons of cargo to bring her down to the load
line.—l am, sir, &c.,

LIVERPOOL AND RUNCORN RAILNN AY.

. TO THE EDITOR OF THE LIVERPOOL STANDARD.
Sll2,—Your paper having supplied a comprehensive
leading article on the subject of Liverpool railway im-
provements, I heg leave to inquire on what grounds the
project of a direct line between Runcorn and Liverpool
has been so suddenly abandoned.
A scheme of this nature was set forth in the official no-
tice advertised a fortnight ago, but it is no longer in-
cluded in the " Junction's" manifestos, and is not even
mentioned by your contributor.
Is it not highly probable, if not certain, that such a me-
dium of communication will hereafter, and at no distant
period. be deemed essential to the mutual interests of
Runcorn and Liverpool, to say nothing of its being part
of the compendious route of a straight line between the
latter town and Birmingham, by which, in the present era
of steam travelling, those two places ought surely to be
conjoined ? When this improvement has been effected,
the Runcorn and Huyton line will be worse than useless,
existing only in the form of an incumbrance on the tract
of country subjected to it—one indeed which the promo-
ters ought to be deterred from inflicting. I know no rea-
son why anything short of the highest degree of perfection
should content the public at Liverpool more than else-
where.—l am, sir, &c. L. P.
