“This,” said he, touching the volume, “is the 'Whole Art and Mystery of Physic,' by one Fabricius, of Aquapendente; and if we don't find a cure for the case down here, take my word for it, it's among the morba ignota, as Paracelsus says.”

“Well, come along,” said Craggs, impatiently, and set off at a speed that, notwithstanding Billy's habits of foot-travel, kept him at a sharp trot. A few minutes more saw them, with canvas spread, skimming across the lough, towards Glencore.

“Glencore—Glencore!” muttered Billy once or twice to himself, as the swift boat bounded through the hissing surf. “Did you ever hear Lady Lucy's Lament?” And he struck a few chords with his fingers as he sang:—

“'I care not for your trellised vine,
I love the dark woods on the shore,
Nor all the towers along the Rhine
Are dear to me as old Glencore.
The ragged cliff, Ben Creggan high,
Re-echoing the Atlantic roar,
Are mingling with the seagull's cry
My welcome back to old Glencore.'

And then there's a chorus.”

“That's a signal to us to make haste,” said the Corporal, pointing to a bright flame which suddenly shot up on the shore of the lough. “Put out an oar to leeward there, and keep her up to the wind.”

And Billy, perceiving his minstrelsy unattended to, consoled himself by humming over, for his own amusement, the remainder of his ballad.

The wind freshened as the night grew darker, and heavy seas repeatedly broke on the bow, and swept over the boat in sprayey showers.

“It's that confounded song of yours has got the wind up,” said Craggs, angrily; “stand by the sheet, and stop your croning!”

“That's an error vulgaris, attributing to music marine disasters,” said Billy, calmly; “it arose out of a mistake about one Orpheus.”
