A few days later, Gerald was seated in one of the large conservatories, reading a book which he had borrowed. Both he and Jack could now read the Martian language fairly well, and they found in the library on board a new storehouse of wonders of the most fascinating description. Hearing footsteps, he glanced up, and saw that Tom Clinch had come to seek him.

'Could I 'ave a wurd wi' you, Mr Gerald?' Clinch asked.

'Certainly, Tom. What's the trouble?'

'Well, Mr Gerald, it be like this. I've 'eerd—it's odd 'ow things do get about—as we was nearly run down t'other night by a comet or some such blamed foolishness.'

Gerald looked with surprise upon the weather-beaten features of the faithful henchman, and with difficulty repressed a smile as he noted their woe-begone expression.

'I don't know how you managed to learn so much, Tom,' he answered quietly; 'but something of the kind did occur, I believe. Still, there is no occasion for you to take it so seriously. The danger is past; and they tell me it's not likely to happen again during the rest of our journey.'

But Tom Clinch was not so easily comforted. He shook his head with a dissatisfied grunt.

''Ow does they know?' he asked dubiously. 'They doan't keep a proper lookout, Mr Gerald, that's what's the matter, else they 'd 'a sighted this reckless galoot afore she got so near. They'd 'a seen as she wurn't under proper control, an' they should 'a sounded the siren. Why doan't they 'ave somebody perched on the top, outside, in a little sort o' crow's-nest? They could 'ave a speakin'-tube to shout through if ye like.'

'I 'm afraid it wouldn't answer; it would be rather uncomfortable—and, um—well, a little cold for the man outside,' replied Gerald gravely, though his eyes were twinkling. 'But is that all you wish to say?'

'Why, no, sir. Me an' Bob Reid, we've talked it over, an' we's agreed t' offer t' run the look-out for 'em, turn an' turn about, if ye likes. We's old sailors, an' we knows the ropes, an' we 'd keep a proper watch. Seems t' me as the people aboord 'ere be mostly landlubbers, what ain't got no nautical knollidge like.'
