I may here mention, that on a part of the coast of Ascension, where there is a vast accumulation of shelly sand, an incrustation is deposited on the tidal rocks by the water of the sea, resembling, as represented in the woodcut, certain cryptogamic plants (Marchantiae) often seen on damp walls.
Thus far, we have spoken the truth concerning her as she appears at present, but we must remember also that we have seen her only in a condition which may be compared to that of the sea-god Glaucus, whose original image can hardly be discerned because his natural members are broken off and crushed and damaged by the waves in all sorts of ways, and incrustations
have grown over them of seaweed and shells and stones, so that he is more like some monster than he is to his own natural form.
Scarcely any of the items in the above-drawn parallel occurred to Phoebe, whose country birth and residence, in truth, had left her pitifully ignorant of most of the family traditions, which lingered, like cobwebs and incrustations
of smoke, about the rooms and chimney-corners of the House of the Seven Gables.
Nevertheless, the remarkably pointed and lofty roof of the modern palace, bristling with carved eaves, covered with sheets of lead, where coiled a thousand fantastic arabesques of sparkling incrustations
of gilded bronze, that roof, so curiously damascened, darted upwards gracefully from the midst of the brown ruins of the ancient edifice; whose huge and ancient towers, rounded by age like casks, sinking together with old age, and rending themselves from top to bottom, resembled great bellies unbuttoned.
The uncovered part had the appearance of a huge cylinder, caked over and its outline softened by a thick scaly dun-coloured incrustation.
Then suddenly he noticed with a start that some of the grey clinker, the ashy incrustation that covered the meteorite, was falling off the circular edge of the end.
And along the margin where the water sometimes broke was a thick incrustation of salt--pink under the lurid sky.
Its back was corrugated and ornamented with ungainly bosses, and a greenish incrustation blotched it here and there.
Then, again, if you fix your eye upon this strange, crested, comb-like incrustation
on the top of the mass --this green, barnacled thing, which the Greenlanders call the crown, and the Southern fishers the bonnet of the Right Whale; fixing your eyes solely on this, you would take the head for the trunk of some huge oak, with a bird's nest in its crotch.
Presently we came to trees, all charred and brown, and so to a bare place covered with a yellow-white incrustation
, across which a drifting smoke, pungent in whiffs to nose and eyes, went drifting.
I could have cried aloud in exultation when my scrutiny disclosed the almost invisible incrustation
of particles of carbonized electrons which are thrown off by these Martian torches.
