in intellect and integrity have con1ueed toward the
origir ating Of The r.Pc. IN question.
The machinery Il the ship has been delayed, first,
by the tardy arrival Of the shafs AMI heavy fagn,s
whsh exe0.tsd at large forge in Pcnnsyvanii;
sne, secondly, by hi take of the workmen in losst
ing holes ". the tub sheets for the eonden.ers,
which has subsequently compelled their removal ant
renewal. The mistake iniuced q leakage which,
though too ely 1t to b. OF momen; in engoe working
on the lind, It has been judged advisable per-
f,ly TO remedy before this noble ship shall be pr
nitied even to make her rial TIP.
TIE difficulty Of handling the parts Of machinery
where what are ordinarily tii parts compel the u.e
Of powerful tackles and derrick. may be conceived
when the weight Of the principal parts are considered
The main shafts each g feet inches l)nS and 2|i
inches in diameter at the spring bearings and weigh,
finished about "a turs. The wheel tanges weigh
each about 20 uDs each cylinder, witb rs connections
about leo tuns the cOn1ensers complete, about ~
| tuns and the whole engines end wheels, complete,
| about eco tms. The principal and auxiliary
boiler each Of the former Of which contain furnaces,
weigh altogctber about $50 tuus. The pston-rods
are each II inches in diameter, and each crank-po,
IL ch.s. The wrought-iron crsnks, of which there
of couse one on each eide connected by short drag
link, weigh, when bored, pared ard finished, 5 tuns
each. The chief engineer to take charge Of this

| et Robinson, formerly of the Baltic.
| TpE MrRRIa.C-The new steam fligste Me7lmsc,
much admired even in Great Britain for her proper
tons end evident Efficiency seems to possess qni'e
mo, dior defect, that Of insufficient drausht IN her
furi aces. The boilers are Martins patent, containing
meny upr. 1T tubes, between which current of bo;
| gases is compelled to pass, and the difficulty has been
explained TO lie in the position and not in the number
or size of the tubes In the MorImac the tubes which
contain water to be heated ranged zszng like the
rails of worm fence position proved to be far SUI
perior TO straight far absorbing the heat is
concerned, but which by continually changing the
ton of the products OF combustion much etards the
drsupht. That the "calorhneter" Of boiler,
or the sectional area Of tho aue space
through Which these hot gases pass, should bear
certain proper ion TO the area of the crate, estao
ished many years ago; but in this style Of boiler,
perimeu baa determined that the effective ca,ormcter
should lie measured not by the acusl space lel be-
tween the tubes in any given cross-rOw, but by the
clear space which exists in straight line, or which
| can be seen through" between the roEs. In order
TO acitse the gases and bring all their heated parti
c'es in contact with the tubes wtGou too much OBJ
structng their passage, s eIpedient To place me
tv o.neh tubes with their surfaces about an inch and
three eighths apart in the direction across tue boiler
and then to zigzag them three-eighths Of inch in
the longitudinal rows thus leeving the clear epace one
inch wide This is the general design Of the inyeator,
but in the boiler CT the Menimac it appears
that the constructors placed them only the same
distance apart and zigzs eyed them iye-eghths of 40
inch leaving the clear space or true ca.orneter but
three-quarters of an irch between each row. The
Mime sofa, the machinery and boilers of which were
designed by Mr. Martin himself and built at the Navy
| Yard at Washington, is reported to have plenty OF
