a difference is perceptible. The material ocean has been so far mastered
by the wisdom and the heroism of man that we may look for a time to come
when the mystery shall be manifest of its furthest north and south, and
men resolve the secret of the uttermost parts of the sea: the poles also
may find their Columbus. But the limits of that other ocean, the laws of
its tides, the motive of its forces, the mystery of its unity and the
secret of its change, no seafarer of us all may ever think thoroughly to
know. No wind-gauge will help us to the science of its storms, no lead-
line sound for us the depth of its divine and terrible serenity.

As, however, each generation for some two centuries now or more has
witnessed fresh attempts at pilotage and fresh expeditions of discovery
undertaken in the seas of Shakespeare, it may be well to study a little
the laws of navigation in such waters as these, and look well to compass
and rudder before we accept the guidance of a strange helmsman or make
proffer for trial of our own. There are shoals and quicksands on which
many a seafarer has run his craft aground in time past, and others of
more special peril to adventurers of the present day. The chances of
shipwreck vary in a certain degree with each new change of vessel and
each fresh muster of hands. At one time a main rock of offence on which
the stoutest ships of discovery were wont to split was the narrow and
slippery reef of verbal emendation; and upon this our native pilots were
too many of them prone to steer. Others fell becalmed offshore in a
German fog of philosophic theories, and would not be persuaded that the
house of words they had built in honour of Shakespeare was "dark as
hell," seeing "it had bay-windows transparent as barricadoes, and the
clear-stories towards the south-north were as lustrous as ebony." These
are not the most besetting dangers of more modern steersmen: what we have
to guard against now is neither a repetition of the pedantries of
Steevens nor a recrudescence of the moralities of Ulrici. Fresh follies
