You must commence, I say, by dreaming, if you would compel yourself gently to sleep; but before I proceed to introduce to you my list of available prescriptions in this line, I note one with which my readers may possibly be familiar, having learned it in their school-boy days. You will not now be told for the first time, that a drowsy sensation may be induced by musing upon--or dreaming of, which is the same thing--a field of tall and ripe barley, swept by fresh autumnal gales. The rise and fall of each bowed head, with its feathery and graceful spikes, combines well with the undulating motion of the whole and the varied play of light and shade. The idea is otherwise expressed by the British Laureate in "The Poet's Song," one of his minor pieces; "and waves of shadow," says he, "went over the wheat." Nevertheless it is clear that he missed the proper application of the thought, for, in place of lulling the beholder to forgetful repose, the sight seems to have made him break out into a song so loud that wild swans paused to listen in their flight, larks fluttered down to earth, swallows gave up hunting bees, snakes slipped under sprays, wild hawks stared over sparrows stricken under their claws, and the very nightingales were set a-thinking. Truly a sad perversion this of a golden opportunity! But your rhymsters were ever a crazy race. When they deal with their fellows generally, we all know how they botch poor human nature. What, then, can be expected, when poets undertake to figure out one of themselves? Still, let us improve the occasion. Barley-fields or wheat-fields are well enough in their way; only, if you conjure up this image, I would advise you to season it with an abundance of red poppies intermingled with the legitimate crop, and a very careful attempt on your part to number these interlopers one by one, preparatory, if so it please you, to flipping off their heads. With due allowance, therefore, for its lack of novelty, this dream may be admitted into our collection.
