“Into a ship of the line man has put as much of his human patience,
common sense, forethought, experimental philosophy, self-control
habits of order and obedience, thoroughly wrought handwork,
defiance of brute elements, careless courage, careful patriotism,
and calm expectation of the judgment of God, as can well be put
into a space 300 feet long; by 80 feet broad.”—_Ruskin._

“If any body of men have just cause to feel pride in their calling,
and in the fruits of their labour, shipbuilders have. If we
look at the magnitude of the operations of building, launching,
engining, and completing a modern passenger ship of the first
rank, and regard the multiplicity of the arrangements and beauty
of finish now expected, and then think this structure has to brave
the elements, make regular passages, convey thousands of human
souls, and tens of thousands of tons of merchandise every year
across the ocean, in storm or calm, we cannot but feel that they
are occupied in useful human labour. But more than this, there
is a public sentiment surrounding ships that no other mechanical
structures can command. Beautiful churches, grand buildings, huge
structures of all kinds have a certain interest pertaining to them,
but it is different in kind from that which surrounds a ship.
The former are fixed, immovable, inert; the ship is here to-day
and gone to-morrow, building up a history from day to day with
a reputation as sensitive as a woman’s to calumny, and like her
consequently often a bone of contention as well as an object of
admiration.”—_William John._
