Since those days, so different from the day on which I had just seen them strolling along the "front", so different and yet so close in time, they still gave way to fits of laughter, as I had observed that afternoon, but to laughter of a kind that was no longer the intermittent and almost automatic laughter of childhood, a spasmodic discharge which, in those days, had continually sent their heads dipping out of the circle, as the clusters of minnows in the Vivonne used to scatter and vanish only to gather again a moment later; each countenance was now mistress of itself, their eyes were fixed on the goal towards which they were marching; and it had taken, yesterday, the indecision and tremulousness of my first impression to make me confuse vaguely (as their childish hilarity and the old photograph had confused) the spores now individualised and disjoined of the pale madrepore.
