The lesson taught by these ruins would fill volumes. Norrena's accurate historical knowledge and ever ready explanations, with the not less forcible comments of Oqua and others, covered every phase of this wonderful, speedy and peaceful evolution from the Era of Money Despotism to the Era of Man and Universal Freedom, Equality and Fraternity. No wonder, I thought, that these people had preserved the ruins of Kroy as a relic of their Dark Ages and a warning to humanity for all time to come. Here, human selfishness reigned supreme and the people of an entire continent had suffered in order to pour into this greedy maw the wealth which it had no power to consume. And now, this once great center of wealth, pride and fashion, was a solitude. Its aristocratic "four hundred" had actually been starved out by the refusal of the "clodhoppers," "greasy mechanics" and "mudsills," whom they had held in such contempt, to feed and clothe them any longer. Surely this was an object lesson well worthy of the care that had been taken to preserve it from the refining and civilizing hand of labor. Time was slowly obliterating these foot prints of a tyranny from which the people had been emancipated for ages, but it was still important that it should not be entirely forgotten, and there could be no better reminder of the evil that had impoverished and degraded the millions, as well as of the means by which it had been removed, than these ruins and the abandoned heaps of useless gold. After a day among the ruins, and full of serious reflections, we returned to the Silver King and were soon speeding down the bay. We landed at the tower, and from this point the electric cars soon transported us to our great communal home. I was fatigued and retired to my own apartment at once, to think and rest.

[Illustration] NEXT morning at the breakfast table Oqua informed me that a package and letter from Bona Dea to my address, had arrived at an early hour but that it had not been delivered, as they did not wish to disturb my rest. It had been retained in the office subject to my order when I was ready to receive it.
