"Marconigrams coming and going," answered Joe; for the little house alluded to was given up to that recent wonderful invention which allows of messages being sent across space, without the aid and intervention of the customary wires. "The young officer there used to live in our neighbourhood. I once thought of becoming an operator myself, and, in fact, had many lessons from him."

"You had?" asked Sam, staring at Joe; for every hour that the two conversed revealed to Sam that Joe was a little better than the ordinary. Indeed, it is only reasonable that we should be fair, and admit that in coming to such a conclusion Sam was strictly right. After all, emigrants are not made up of the most intelligent or of the highest educated of our population. Too often they are men and women seeking a new life because of the failure of that which they had previously followed; or they are young people with a fair education, and with little else. In Joe's case, thanks to his own restless ambition, and to the fact that his father had devoted many an hour to him, the lad was acquainted with much unknown to the average emigrant. And here was something. To Sam a marconigram was neither fish, flesh, nor fowl; he didn't precisely know what it was, whether it had actual shape, nor what was its colour.

"Eh?" he asked. "You know the chap as works up there? And you've had lessons? What's a marconigram, anyhow?"

Joe explained with enthusiastic lucidity.

"I've sent 'em, too," he said. "There was a station not so far from us, and that's where I met Franc. It's nice having him aboard the same ship. But he is busy, isn't he? There must be something happening out of the ordinary. Wish I could go up there and join him; but it's forbidden. He told me that particularly."

It was only natural that our young hero should wish to see something of a chum associated with former days. But Franc, the young Marconi operator, was never get-at-able when on duty. It was only between the spells of work in his office that he met Joe down on the emigrant deck for'ard. Now, at the time when Sam and Joe were together, Franc was undoubtedly busily engaged. Moreover, there was a subdued air of mystery, if not of anxiety, about the officers who occasionally passed amongst the emigrants.

"What's up?" demanded Sam bluntly of one as he passed. "That thing yonder"—and he again withdrew his pipe and pointed the bowl at the Marconi office—"that thing's busy, I guess. Sending messages as fast as the air'll take 'em. What's up, mister? Revolution back in the Old Country, eh? What?"

He received merely a curt answer; the officer hurried on, leaving Sam none the wiser.

"All the same, there's a ruction stirring somewhere," he said; "I can see it with half an eye. The captain's walking up and down his bridge as if there was lions after him. What's it all mean?"

It became clearer, as the hours passed, that there was something seriously wrong in some direction, though where or what the trouble might be none could guess. Joe descended with his friend to dinner, and it was not till he mounted to the deck again that he gained tidings of what was happening. A huge column of pungent smoke was rising from the fore hold of the ship as he gained the deck, while sailors were moving about with wet cloths tied round their mouths.
