I am not, however, lecturing of Lost Arts in the strain which sings 'there is nothing new under the sun,' and which in a chilling manner benumbs the faith in progress by shaking with a grin before the wearied inventor some skeleton puppet of buried ages, which resembles his great thought as a hut resembles a palace. On the contrary, I find in this strange frequency of anticipation among Indo-Germanic races, and in its premature failures, a vast proof of inventive vitality and of promise of great rising truths into all future ages. 'Steam power is nothing new,' say the advocates of the genius of the past. Hero of Alexandria invented a steam toy--as he who can read his _Spiritalia_ published by the Jesuits in 1693 may learn for himself. But the power now roaring and whizzing all over the world, and which would build every pyramid and every monument of Egypt now extant in twenty-four hours, is no toy. When I think of this, there is no ingenious trifle for amusement which does not inspire a droll awe. Possibly those walking dolls now performing their weary pilgrimages on level glass-pane floors in Broadway windows--gravely lifting those enormous gilded boots, which remind me of Miss Kilmansegg and Queen Berta _à grands piés_, in one--have a good reason for their dignity of gait. For may they not be golden-footed and solemn, like her who rose from the waves of old to prophesy to her son?--and if she was _silver_-footed, it makes no difference, for so are some of the _autoperiper_--nay, _that_ word finishes me, and I go no further. Such a block of Greek would bring even a German sentence down with a crash to a verbless conclusion. What I would have said was, that it may be that these dolls are heralds of greater dolls yet to come, which shall be wound up to fetch and carry, to sew on buttons--nay, it is even possible (in the wildest of dreams) that they may be made to boil potatoes properly. And I have been told that a recent improvement in boys' rocking horses, by means of which a trotting motion is given to the legs of those docile animals, has suggested to a mechanic of this city the construction of a very good automatic steed, whose only fault is slowness. May I suggest that a very great improvement indeed may yet be made on that horse, and that the two-forty of a coming generation may be the result, not of oats and hay, but of steel springs and cylinders? The first wooden horse burnt Troy--what will the last do? I have been reminded of the strange tendency in man--but more especially of the Indo-Germanic or Aryan man--to anticipate by invention the wants of an age, sometimes centuries beforehand--by turning over that very curious work, the 'Century of Inventions,' by the Marquis of Worcester, in which, as in the commonplace book of an author, one may find jotted down many an undeveloped idea of great promise. In this connection we may be allowed to borrow somewhat from a biography by Charles F. Partington, published in 1825.
