A poet whose lyrics were of this type might be expected to find in drama proper his free, full, and natural expression. This was not altogether the case with Browning, who, despite an unquenchable appetency for drama, did better work in his dramatic monologues than in his plays. The drama alone allowed full scope for the development of plot-interest. But it was less favourable to another yet more deeply rooted interest of his. Not only did action and outward event--the stuff of drama--interest Browning chiefly as "incidents in the development of soul," but they became congenial to his art only as projected upon some other mind, and tinged with its feeling and its thought. Half the value of a story for him lay in the colours it derived from the narrator's personality; and he told his own experience, as he uttered his own convictions, most easily and effectively through alien lips. For a like reason he loved to survey the slow continuities of actual events from the standpoint of a given moment, under the conditions of perspective and illusion which it imposed. Both these conditions were less well satisfied by drama, which directly "imitates action," than by the dramatic speech or monologue, which imitates action as focussed in a particular mind. And Browning's dramatic genius found its most natural and effective outlet in the wealth of implicit drama which he concentrated in these salient moments tense with memory and hope. The insuppressible alertness and enterprise of his own mind tells upon his portrayal of these intense moments. He sees passion not as a blinding fume, but as a flame, which enlarges the area, and quickens the acuteness, of vision; the background grows alive with moving shapes. To the stricken girl in _Ye Banks and Braes_ memory is torture, and she thrusts convulsively from her, like dagger-points, the intolerable loveliness of the things that remind her of her love; whereas the victim of _The Confessional_ pours forth from her frenzied lips every detail of her tragic story.
So in _The Laboratory_, once more, all the strands of the implicit drama are seen like incandescent filaments in the glow of a single moment of fierce impassioned consciousness:--
