INSTITUyION:OF CIVIL EN-

GINEERS.---MAncx 10.
(Sir JOHN RENNIE, President, in the chair.)
The paper of the evening was an " Account of the
Drops used for the shipment of Coals at Middlesborough-
on-Tee, with a description of the town and port of Mid-
dlesborough," by George Turnbull, M. Init. C. E.
The communication first gave an account of the town
of Middlchorough-on-Tees,and then &scribed the docks,
ind the coal drops used there.
„The rapid rise of the
town into commercial importance was treated of and
accounted for, chit fly by the fact of a branch having been
constructed from the Stockton and Darlington Railway
to Middlesborough, which, as a port for shipping, pos-
sessed many advantages over Stockton. As an example
of this increased importance, it was stated, that the
quantity of coals sent down the Stockton and Darlington
Railway and shipped at Stick ton and Middleborough,
in :825-26, was 7,926 tons ; and in 1840-41 it had in-
creased
to the comparatively immense amount of 498,092,
tons. The handsome manner in which 'the town was
laid out and built, and its active manufactories, were
also noticed.

This commercial activity necessarily caused the want
of a dock to be felt, and the present works were accord-
ingly executed.

Vile approach to the dock was stated to be by a chan-
nel of more than a quarter of a mile in length, which
was kept open by sluicing ; the entrance lock, built of
stone, was 132 feet long by 30 feet wide, the area of the
dock itself was about nine acres.
The branch railway diverges from the Stockton and
Darlington line, and terminates in ten double lines, lead-
ing to the ten coal drops. The manner of working the
drops was thus described:—The loaded waggon is run
on to a cradle or stage, which is arrested in a position
immediately Over the hatchway of the vessel to be
loaded; it is then let down perpendicularly, by means of
counerbalance weights, and when it has nearly reached
the deck of the vessel the contents are discharged into
the hold; the counterbalance weights then preponde-
rate, and the empty waggon is raised to the level of the
rails. At the ordinary rate of working, about thirty
waggons can be discharged an hour by each drop.
In a statement annexed to the paper, it is mentioned
that in the year ending July 1, 1845, 505,486 tons of
coals were shipped by means of the ten drops here
described. The cost of the drops was 7,300/. The total
outlay for the whole works amounted to 122,000/. These
works were designed by Mr. W. Cubit, Vice-President
of the Institution of Civil Engineers, Mr. G. Turnbull
being theacting engineer.
Mr. Slemen's chronometric governor was exhibited,
and after being explained to the meeting, its merits as a
regulator of machinery were testified to by several gen-
tlemen who had used it for corn and other mills, and it
was acknowledged to be very superior to the ordinary
pendulum governor of Mr. Watt.
The following paper was announced to be read at the
meeting of Tuesday, March 17 :
N. 734.—0 n the relation between the velocity and
the resistance encountered by bodies moving in fluids,
by J. M. Heppe], Graduate of this Institution.

TESTIMONIAL TO MR. BENCRAFT IN VESPECT TO lIIS

SADDLE

We cannot do less than give the following, as corroborative of what
is stated in the public announcement in respect to Mr. P.ancraft's
invaluable patent. The authority we now quote will quiet the minds
of the most sceptical, and prove that in the multitude of every-day
improvements the march of the mind has in nothing..else exceeded
the patent now under our consideration :

Croydon, March 4, 1846.
Dear Sir,—lt is with peculiar pleasure that I tender the following
remarks upon your -highly-important inventions, viz.:--" The Pa-
tent Thunes," and " Elastic Spring Saddle." For the last twelve--
months I have had the !tames almost in daily use, upon a variety of
horses; my joarnies have been long, on roads of ti ariablo charactet%
not. unfrequently has-big to ascend hills of unusual aelivities, coarsely
',ravelled. These tests have per4ixtly-convin,,,,l me that toy hors,
have receivcd.a 6.re,41 bOOl4- •
The distinguished features of merit are thy cl,se a‘laptat ion 4., IL.,
collar, and the nniformity of its presaora cpon all proper seais of
bearin-, the patent 'tames, aahaitting of such a salutary division of
the points, thereby not only affording increased facilities On' draught,
but avoiding, all abrasion.

These circumstances combined have a temlewy to diminish or re-
riove a bad habit acquired by some horses called heaving, or break--
ng into a sort of half canter, a sad bane with many otherwise good
muggy horses.

I am also able to bear testimony that by using your hawea
galled shoulders may be healed in the inlil4 of work.
Your elastic spring-saddle I have ridden upon, within the last nine
months, some thousands of miles, the average number being from
ten to fifteen miles per day upon the road, including two' days a
week severe stag-hunting; the same saddle possessing the singular
quality of fitting three of my horses.

" I am of• opinion that concussion to the hunter carrying high
weight is avoided in almost endless variety, during an arduous
chase, owing to the construction of your elastic spring saddle re-
lieving the ridge 'of the spine from pressure, and diffusing or
equalising the burden over a more extended muscular surface ;
this must tell not only in speed, but I apprehend far more in a suc-
cession of difficult fencing, where the animal is-required, with the
weight of his rider, 'first to elevate, secondly, to elongate, and
thirdly, to land himsclf :irmly and judiciously.
With such extraordinary denumds upon this noble aalmal's muscu-
lar powers, a diffusible spring, well arranged, must be a grand desi-
deratum to every sportsman's saddle.

I ain,dear Sir, yours truly,
THOMAS TURNER,
rre,iident of the Royal College of Veterinary Sitrgeons.

INACCURATE POSITION OF CAP.GODAS, CARAYGOS, AND

FRIGATE BLAND.

Commander A. G. Wall, of H. C. S. V. Tenesserim,
in a letter (a copy of which has been forwarded to
Lloyds) addressed by him to the master•attendant at
Ceylon, states, that the positions of the above-named
island sre erroneously laid down in Horsburgh's last
charts, thirty miles to the eastward of the actual
position, though the error is corrected in the last edition

LATE OUTRAGES at CAMBRIDGE.
TO THE EDITOR OF THE SUN.
SIR,—You will al'
ige b y allowing me to put a ques-
tion (through the medium of your journal) to Mr. Fisher
and Captain Bailey—the case of assault being clearly
proved against the Hon. G. Calthrop, why it was
abandoned, and, for a similar offence, why was the other
gentleman, Mr. Billy Moden, fined 10s. ? So long as
outrages on public order and decency are thus connived
at, and dealt with, what may we expect but a recurrence
of such manifestations of aristocratical buffoonery, to
the clanger and annoyance of every peaceable citizen. If
the farce here acted is not an evasion of the law, and a
corruption of the civil force, what is ?
I am, Sir, yours respectfnlly,

the present in Saekville-street, Dublin, " and who was for many
years in the East India Company's service, fell into ill-health, and
was even at death's door, the action of his heart being fregiently so

from shortness of breath and debility he could scarcely walk twenty

thata.proposition, originating with Mr Creed, of the London

companies, to present some acknowledgment to Mr. Charles
Nash, far his indefatigable exertions in prosecuting to con-
viction Maynard and Garrett, and breaking up the gang of
luggage robbers. Mr. Nash most strongly merits such a tes-

the United Kingdom that will not contribute towards it.
The suppression of these robberies has benefited them
