“You don’t say so!” returned Slagg, who, being utterly uneducated, received suchlike information with charming surprise, and regarded Robin as a very mine of knowledge. “Well now, that beats cock-fighting. But, I say, how is it that the electricity works through the cable? I heerd one o’ your electrical fellers explaining to a landlubber t’other evenin’ that electricity could only run along wires when the circuit was closed, by which he meant to say that it would fly from a battery and travel along a wire ever so far, if only that wire was to turn right round and run back to the same battery again. Now, if that’s so, seems to me that when you’ve got your cable to Newfoundland you’ll have to run another one back again to Ireland before it’ll work.”

“Ah, Slagg, that would indeed be the case,” returned Robin, “were it not that we have discovered the important fact that the earth—the round globe on which we stand—itself acts the part of a grand conductor. So we have only to send down earth-wires at the two ends—one into the earth of Ireland, the other into the earth of Newfoundland, and straightway the circuit is closed, and the electricity generated in our batteries passes through the cable from earth to earth.”

“Robin,” said Slagg doubtingly, “d’you expect me for to believe that?”

“Indeed I do,” said Robin simply.

“Then you’re greener than I took you for. No offence meant, but it’s my opinion some o’ these ’cute electricians has bin tryin’ the width of your swallow.”

“No, you are mistaken,” returned Robin earnestly; “I have read the fact in many books. The books differ in their opinions as to the causes and nature of the fact, but not as to the fact itself.”

It was evident that Robin looked upon this as an unanswerable argument, and his friend seemed perplexed.

“Well, I don’ know how it is,” he said, after a pause, “but I do believe that this here wonderful electricity is fit for a’most anything, an’ that we’ll have it revoloosionising everything afore long—I do indeed.”

The intelligent reader who has noted the gigantic strides which we have recently made in electric lighting of late will observe that Slagg, unwittingly, had become almost prophetic at this time.

“We’re going along splendidly now,” said Mr Smith, coming up to Robin that evening while he was conversing with Slagg, who immediately retired.—“Who is that youth? He seems very fond of you; I’ve observed that he makes up to you whenever you chance to be on deck together.”
