strife of hostile parties.  Here the corruption which debases democracies was as unknown as the discontents which undermine the thrones of monarchies.  Equality here was not a name; it was a reality.  Riches were not persecuted, because they were not envied.  Here those problems connected with the labours of a working class, hitherto insoluble above ground, and above ground conducing to such bitterness between classes, were solved by a process the simplest,—­a distinct and separate working class was dispensed with altogether.  Mechanical inventions, constructed on the principles that baffled my research to ascertain, worked by an agency infinitely more powerful and infinitely more easy of management than aught we have yet extracted from electricity or steam, with the aid of children whose strength was never overtasked, but who loved their employment as sport and pastime, sufficed to create a Public-wealth so devoted to the general use that not a grumbler was ever heard of.  The vices that rot our cities here had no footing.  Amusements abounded, but they were all innocent.  No merry-makings conduced to intoxication, to riot, to disease.  Love existed, and was ardent in pursuit, but its object, once secured, was faithful.  The adulterer, the profligate, the harlot, were phenomena so unknown in this commonwealth, that even to find the words by which they were designated one would have had to search throughout an obsolete literature composed thousands of years before.  They who have been students of theoretical philosophies above ground, know that all these strange departures from civilised life do but realise ideas which have been broached, canvassed, ridiculed, contested for; sometimes partially tried, and still put forth in fantastic books, but have never come to practical result.  Nor were these all the steps towards theoretical perfectibility which this community had made.  It had been the sober belief of Descartes that the life of man could be prolonged, not, indeed, on this earth, to eternal duration, but to what he called the age of the patriarchs, and modestly defined to be from 100 to 150 years average length.  Well, even this dream of sages was here fulfilled—­nay, more than fulfilled; for the vigour of middle life was preserved even after the term of a century was passed.  With this longevity was combined a greater blessing than itself—­that of continuous health.  Such diseases as befell the race were removed with ease by scientific applications of that agency—­life-giving as life-destroying—­which is inherent in vril.  Even this idea is not unknown above ground, though it has generally been confined to enthusiasts or charlatans, and emanates from confused notions about mesmerism, odic force, &c.  Passing by such trivial contrivances as wings, which every schoolboy knows has been tried and found wanting, from the mythical or pre-historical period, I proceed to that very delicate question, urged of late as essential to the perfect happiness of our human species by the two most disturbing and potential influences on upper-ground society,—­Womankind and Philosophy.  I mean, the Rights of Women.
