I know that it is a hazardous experiment to address myself again to a public which in days long past has given me a generous welcome. But my readers have been, and are, a very faithful constituency. I think there are many among them who would rather listen to an old voice they are used to than to a new one of better quality, even if the “childish treble” should betray itself now and then in the tones of the overtired organ. But there must be others,--I am afraid many others,--who will exclaim: “He has had his day, and why can't he be content? We don't want literary revenants, superfluous veterans, writers who have worn out their welcome and still insist on being attended to. Give us something fresh, something that belongs to our day and generation. Your morning draught was well enough, but we don't care for your evening slip-slop. You are not in relation with us, with our time, our ideas, our aims, our aspirations.” Alas, alas! my friend,--my young friend, for your hair is not yet whitened,--I am afraid you are too nearly right. No doubt,--no doubt. Teacups are not coffee-cups. They do not hold so much. Their pallid infusion is but a feeble stimulant compared with the black decoction served at the morning board. And so, perhaps, if wisdom like yours were compatible with years like mine, I should drop my pen and make no further attempts upon your patience. But suppose that a writer who has reached and passed the natural limit of serviceable years feels that he has some things which he would like to say, and which may have an interest for a limited class of readers,--is he not right in trying his powers and calmly taking the risk of failure? Does it not seem rather lazy and cowardly, because he cannot “beat his record,” or even come up to the level of what he has done in his prime, to shrink from exerting his talent, such as it is, now that he has outlived the period of his greatest vigor? A singer who is no longer equal to the trials of opera on the stage may yet please at a chamber concert or in the drawing-room. There is one gratification an old author can afford a certain class of critics: that, namely, of comparing him as he is with what he was. It is a pleasure to mediocrity to have its superiors brought within range, so to speak; and if the ablest of them will only live long enough, and keep on writing, there is no pop-gun that cannot reach him. But I fear that this is an unamiable reflection, and I am at this time in a very amiable mood.
