ENGLISH AND AMERICAN IRON-I

CASED SHIPB.

The opening meeting of the Institution of Naval
Architects, held yesterday at the hall of the Society
of Arts—the Right Hon. Sir J. S. Pakington in the
chair—was signalised by a circumstance of great
scientific and scarcely less public interest. After
reading the report of the Council, in which the
members and associates were congratulated upon
the extraordinary success of the institution, the
secretary, Mr, E. J. Reed, announced that he had
received a letter from the Hon. Captain Cochrane,
in command of her Majesty's steamer Warrior, ac-
companied by a chart or diagram of a perfectly
novel kind, in which what might be called a com-
plete scientific record of that vessel's voyage to
Lisbon and Gibraltar and home again was set forth.
Some idea of the value of this document and of the
extraordinary knowledge and skill exhibited by
Capt. Cochrane in its composition may be gatherod
from the remarks with which the secretary laid it
before the institution. Mr. Reed stated that the
paper had been placed in his hands only a very few
hours before the meeting assembled, and that he
had consequently had no time to give it a detailed
examination, or to extraet from it those valuable
facts which it manifestly contained ; but he had
found opportunity for examining it sufficiently to
discover that it was by far the most perfect and
important record of a steam voyage that had
ever been brought to the notice of a scientific
man.

This statement was made not alone on
account of the variety and exactness of the in-
formation which it afforded, but also because
a very remarkable amount of scientific acumen and
judgment had been brought to bear upon the
methods of record which Captain Cochrane had in-
troduced into it. The diagram consisted substan-
tially of three sets of facts. First, those which
related to the state of the wind and sea at every
point of the ship's ,progress ; secondly, those which
concerned the ship herself, especially as regarded
her behaviour ; and, thirdly, those which depended
upon the performance of the engines ofa the ship.
Under the first head are recorded from hour to hour
throughout the entire voyage the force of the wind,
and its direction relatively to the ship's course, the
atmospheric pressure indicated by the barometer,

and the direction and amount of the sea's swell.
Under the second head are given the draught of
water, displacement, and midship section of the
ship, the speed at which she went, the sail which
she had set, and the duration and extent of her
pitches, rolls, and lurches. Under the last head
Captain Cochrane states the quantity of fuel con-
sumed, the number of boilers at work, the grade of
expansion to which the side links were set, the
actual indicated power given out by the engines,
the number of revolutions made by the screw, the
proportion of coal burnt per horse-power per
hour ; and the miles run per ton of coal under
all circumstances. Those various facts, which
are of vital importance in a scientific point
of view, and by no means unimportant in their
bearing upon the economical working of our im-
mense navy, are brought together in so ingenious
and perfect a manner in Captain Cochrane's
diagram that all of them may be ascertained at
a single glance for every hour throughout the entire
voyage to Gibraltar and back. There can be no
doubt, as the Secretary observed, that if the Admi-
ralty could secure records like these from officers
in command of our seagoing ships, and would liber-
ally sanction, as they have done in this case, their
communication to such professional persons as were
then assembled, most valuable results would
speedily follow. It may, perhaps, be doubted
whether some of our naval captains would be com-
petent even to imitate the work which Captain
Cochrane has so ably and laboriously initiated; but
there are many by whom the task would be speedily
mastered, and others would gradually fit themselves
for it when they knew the Admiralty were anxious
to see it done. It may be interesting to mention
that, from Mr. Reed's explanatory statement it ap-
peared that the Warrior rolled or lurched worst on
January 24, when entering the Bay of Biscay,
where she met with exceedingly heavy rollers nearly
a-beam, and a head sea. The greatest angle through
which she lurched on that day was 39 deg., mea-
sured from the extremes. This was at 7 o'clock in
the morning, and she continued to lurch through
angles exceeding 30 deg. at intervals until 12
o'clock, the rolls being measured in all cases
by a clinometer placed 20ft, 6in, before the
foremost sternpost, and 3ft. 6in. below the upper
deck. It was even stated by some on board
that the ship inclined three several times on
this 24th of January through angles exceeding
39 deg.; but the correctness of the observations
in these cases is doubted. On the homeward
voyage on such extreme rolling was experienced,
the greatest inclinations then attained being 17 deg.
to port and 6 to starboard on one occasion, and 10
to port and 15 to starboard on another. It should
be observed, however, that the time of rolling, taking
the worst days on the outward and homeward
a voyage respectively for comparison, did not vary
greatly,
the average oscillation being in the former
