Ammonites, and such small geological fry, were to be found by the thousand in the petrified mud beds of the Cobb region; but it was left to the ingenuity, aided by good fortune, of the foreigner to unearth from the flaking and perishing cliffs of lias some of the earliest and finest specimens of the ichthyo- and plesio-saurus that a past world has yielded to the naturalists.

Out of these the émigré made money, and so was enabled to pursue and enlarge upon his researches. Presently he prospered into a competence, married (poor Mademoiselle Belleville, of the Silver Street Academy, who died of typhoid at the end of a couple of summers), and so grew into the kindly old age of the absorbed and gentle naturalist, with his Plancine budding at his side.

What in all these fifty years had he forgotten? His name, his rank, his very origin? Much, no doubt. But that there was one haunting memory that had dwelt with him throughout, his child and her lover were to learn—one memory, and that dreadful recurring illusion of the guillotine.

"When Black Venn slips his apron, I shall be in a position to consider your suit."

Surely that was an odd and enigmatical condition, entirely remote from the subject at issue? Yet from the moment of the first impassioned pleadings of the stricken George, De Jussac had insisted upon it as one from which there should be no appeal.

Now the Black Venn referred to was a great mound of lias that rolled up and inland, in the far sweep of the bay, from the giddy margin of the lower ruin of cliffs. These—mere compressed mountains of mud, blown by the winds and battered by the sea—were in a constant state of yawn and collapse. Yard by yard they yielded to the scourge of Time, and landslides were of common occurrence.

All along the middle slope of Black Venn itself, a wide, deep fissure, dark and impenetrable, had stretched from ages unrecorded. But the eventual opening-out of this crevasse, and the consequent subsidence of the incline, or apron, below it, had been foretold by Mr. De Jussac; and this, in fact, was the condition to which he had alluded.

"Mr. De Jussac! do you hear me?"

"I am coming, my friend."
