Of these, one was the _Orion_, on board of which Tremayne was visiting the various centres of the Brotherhood throughout the English-speaking world, making everything ready for the carrying out at the proper time of the great project to which he had devoted himself since the memorable night at Alanmere, when he had seen the vision of the world's Armageddon. The other was under the command of Michael Roburoff, who was busy in America and Canada perfecting the preparations for checkmating the designs of the American Ring, which were described in a former chapter. The remainder of the members of the Inner Circle and those of the Outer Circle, living in Aeria, were quietly pursuing the most peaceful avocations, building houses and water-mills, clearing fields and laying out gardens, fishing in the lake and streams, and hunting in the forests as though they had never heard of the horrors of war, and had no part or share in the Titanic strife whose final issue they would soon have to go forth and decide. One of the hardest workers in the colony was the Admiral of the aërial fleet. Morning after morning he shut himself up in his laboratory for three or four hours experimenting with explosives of various kinds, and especially on a new form of fire-shell which he had invented, and which he was now busy perfecting in preparation for the next, and, as he hoped, final conflict that he would have to wage with the forces of despotism and barbarism. The afternoons he spent supervising the erection of the mills, and the construction of new machinery, and in exploring the mountain sides in search of mineral wealth, of which he was delighted to find abundant promise that was afterwards realised beyond his expectations. On these exploring expeditions he was frequently accompanied by Natasha and Radna and her husband. Sometimes Arnold would be enticed away from his chemicals, and his designs on the lives of his enemies, and after breakfasting soon after sunrise would go off for a long day's ramble to some unknown part of their wonderful domain, in which, like children in a fairyland, they were always discovering some new wonders and beauties. And, indeed, no children could have been happier or freer from care than they were during this delightful interval in the tragedy in which they were so soon to play such conspicuous parts. The two wedded lovers, with the dark past put far behind them for ever, found perfect happiness in each other's society, and so left, it is almost needless to add, Arnold and Natasha pretty much to their own devices. Indeed, Natasha had more than once declared that she would have to get the Princess to join the party, as Radna had proved herself a hopeless failure as a chaperone.
