Iers.
The recent jubilee in Boston was not simply for
the purpose Of celebrating the completion of line
of railway connecting that city with Montre al but
likewise the establishment of line Of propellers to
run between Boston and Liverpool.
The line is composed Of two very fine vessels
Gale the s. S. Lewis, after the enterprising and
spirited gentleman who organized the line, and who
owns great portion of the stock, and the Benjamin
Franklin. Both are beautiful specimens of naval
architecture, and will, no doubt, give a good ac-
count of themselves. These vessels are SO much
alike that description of will answer for the
other. The hull of the s. S. Lewis was built by
Messrs. Birely & Sons, and is most substantially
built and fastened Her frame i, almost entirely Of
white oak, and the plankng and ceiling principally
Of the same material Her floor timbers are q solid
bed of oak, from the stern post to midships, each
piese being bolted hngontally to one another, and
vertically through the timbers. The frame is
bound together with diagonal iron braces, each
sixty feet long, five inches wide and inch thick
These braces cross one another, are let into the
timbers, being bolted through them, and rivited
the outside, and at every intersection are bolted
together In iron fasenipgs alone, exclusive Of the
fame brace, she has l25 900 lbs, beside l00 600 lbs
ofcopper, and 5000 lbs, of composition. Below the
main deck. u, COO bolts have been driven from the
outside, through all, and rveted on the inside.
The number OF knees used in her construction Is S45
The interior arrangements of the 5. 5. Lewis are
admirable. NO space Is lost, and she can carry
as many passengers and as much freight as any
vessel Of her size in the world. She has on deck
house l30 feet in length, the top Of which forms
spacious promenade for her passengers, the sides
being protected by tasty brass railing. The after
division extends across the deck, and contains the

q gsngwsy Of seven and q half fee. wide. This
house contains the mess room and state rooms 70.
the officers and engineers Of the ship, captains
cabin, hatchways leading to the cabins and engine
one Of Woods patent cabooss stoves. The main
saloon contains thirty staterooms, and Is paneed,
set of with pilasters and cornices, edged with
beautiful carving and frnged with gold and silver.
The arrangements for securing ventilation are per-
feet; between each beam there are perforated ven-
tila.ors communicating With the state rooms. The
wood work Of the cabin Is plain enamelled white.
There are four stern windows, with m ost luxuri-
sofa beneath which accords with the rect Of the
furniture. The forward part Of the main deck Is
designed for second class passengers and Is vent-
lated in the same manner as the principal saloon.
The forward and after portions Of the lower deck,
clear Of the engine room, which occupies but
small comparative fpace, can be devoted to steerage
passengers or the stowsge ofcargo.
The 5. 5. Lewis has one OF Loper's propellers,
worked by engines, which, for compactness,
admiration Of all vho have seen them The cyln-
ders are ofthe angular pattern, the cylinders being
at the sides inclined TO an angle Of - degrees, the
Of the piston, graspng the crank In the centre,
ard acting upon 1t reciprecally. The bed plate Is
Of cast iron, II feet long, IL wide, and inches
thick, with the channels from the cylinder to the
air pumps themselves formed In 1t. The main
crank or driving shaft, Is of wrought iron, l7nches
in diameter, aud II feet long, with driving wheel
feet in pameter by 81 feet face geared to the pro.
peier shaft TO drive II at the rate Of IL turns TO
every revolution. The propeller shaft is III inches
in diameter, 67 feet long, and Is in three pieces,
coupled together The air pumps are so constructed
that, should any accident occur to them, they can
be detached in Eve minutes, and the engines work
on the high pressure principle as If nothing had
happened
The propeller is an object of great interest, and
has excitsd general admiration. The diam ,ter Of
the wheel is IL feet inches, with four fan shaped
blades, set at an angle of 30 degrees. The extreme
width Of the outer edge Of the "fans" is feet,
while the direct width across the blades, while re-
volvipg, is 80 feet The wheel is Of solid iron,
and is set at pitch Of p feet
The people Of Boston are proud, and very justly
so, Of these beautiful propellers They reflect
credit on the city. The time Is fast approaching
when Iropelers OF the class and description of the
= 5. Lewis and BENJAMIN Franklin, will perform
the greater part Of the carrying trade between the
United States and the Old Wsrld.
