score sister-craft of the same type embody his latest ideas. But she is not comfortable. An A.B.C. boat does not take the air with the level-keeled lift of a liner, but shoots up rocket-fashion like the 'aeroplane' of our ancestors, and makes her height at top-speed from the first. That is why I found myself sitting suddenly on the large lap of Eustace Arnott, who commands the A.B.C. Fleet. One knows vaguely that there is such a thing as a Fleet somewhere on the Planet, and that, theoretically, it exists for the purposes of what used to be known as 'war.' Only a week before, while visiting a glacier sanatorium behind Gothaven, I had seen some squadrons making false auroras far to the north while they manœuvred round the Pole; but, naturally, it had never occurred to me that the things could be used in earnest.
Said Arnott to De Forest as I staggered to a seat on the chart-room divan: 'We're tremendously grateful to 'em in Illinois. We've never had a chance of exercising all the Fleet together. I've turned in a General Call, and I expect we'll have at least two hundred keels aloft this evening.'
'Well aloft?' De Forest asked.
'Of course, sir. Out of sight till they're called for.'
Arnott laughed as he lolled over the transparent chart-table where the map of the summer-blue Atlantic slid along, degree by degree, in exact answer to our progress. Our dial already showed 320 m.p.h. and we were two thousand feet above the uppermost traffic lines.
