I have sometimes tried, but in vain, to discover the law which regulates the attainment of extreme popularity. Extreme popularity, in this country and age, appears a very arbitrary thing. I defy any person to predict a priori what book, or song, or play, or picture, is to become the rage,--to utterly transcend all competition. I believe, indeed, that there cannot be popularity for even a short time, without some kind or degree of merit to deserve it; and in any case there is no other standard to which one can appeal than the deliberate judgment of the mass of educated persons. If you are quite convinced that a thing is bad which all such think good, why, of course you are wrong. If you honestly think Shakspeare a fool, you are aware you must be mistaken. And so, if a book, or a picture, or a play, or a song, be really good, and if it be properly brought before the public notice, you may, as a general rule, predict that it will attain a certain measure of success. But the inexplicable thing--the thing of which I am quite unable to trace the law--is extreme success. How is it that one thing shoots ahead of everything else of the same class; and without being materially better, or even materially different, leaves everything else out of sight behind? Why is it that Eclipse is first and the rest nowhere, while the legs and wind of Eclipse are no whit better than the legs and wind of all the rest? If twenty novels of nearly equal merit are published, it is not impossible that one shall dart ahead of the remaining nineteen; that it shall be found in every library; that Mr. Mudie may announce that he has 3250 copies of it; that it shall be the talk of every circle; its incidents set to music, its plot dramatized; that it shall count readers by thousands while others count readers by scores; while yet one cannot really see why any of the others might not have taken its place. Or of a score of coarse comic songs, nineteen shall never get beyond the walls of the Cyder Cellars (I understand there is a place of the name), while the twentieth, no wise superior in any respect, comes to be sung about the streets, known by everybody, turned into polkas and quadrilles and in fact to become for the time one of the institutions of this great and intelligent country. I remember how, a year or two since, that contemptible Rat-catcher's Daughter, without a thing to recommend it, with no music, no wit, no sentiment, nothing but vulgar brutality, might be heard in every separate town of England and Scotland, sung about the streets by every ragged urchin; while the other songs of the vivacious Cowell fell dead from his lips. The will of the sovereign people has decided that so it shall be. And as likings and dislikings in most cases are things strongly felt, but impossible to account for even by the person who feels them, so is it ffith the enormous admiration, regard, and success which fall to the lot of many to whom popularity is success.
