After a while of this quivering suspense she gave a low call, a long mellow and tremulous cry which, gentle as it was, startled by its suddenness, as the unexpected call of a water-fowl out of the reeds of a pond makes the heart jump toward the throat. It was like some bird's call, but I know of no bird's with which to get a close comparison. It had the soft quality, soft yet piercing, of a redshank's, but it shuddered like an owl's. And she held it on as an owl does. But it was very musical, soft and open-throated, and carried far. It was answered from a distance, first by a single voice; but then another took it up, and another; and then another. Slowly so the soft night was filled with musical cries which quavered about me as fitfully as fire-flies gleam and glance in all quarters of a garden of olive-trees. It was enchantment to the ear, a ravishing sound; but it was my eyes which claimed me now, for soon I saw them coming from all quarters. Or rather, I saw them there, for I can't say definitely that I saw any one of them on the way. It is truer to say that I looked and they were there. Where had been one were now two. Now two were five; now five were a company; now the company was a host. I have no idea how many there were of them at any time; but when they joined hands and set to whirling in a ring they seemed to me to stretch round Parliament Hill in an endless chain.
How can I be particular about them? They were of both sexes--that was put beyond doubt; they were garbed as the first of them in something translucent and grey. It had been quite easy in the lamplight to see the bare form of the woman whom I first saw in Gaylord's Rents. It was plain to me that her companions were in the same kind of dress. I don't think they had girdles; I think their arms and legs were bare. I should describe the garment as a sleeveless smock to the knees, or perhaps, more justly, as a sack of silky gauze with a hole for the head and two for the arms. That was the effect of it. It hung straight and took the folds natural to it. It was so light that it clung closely to the body where it met the air. What it was made of I have no notion; but it was transparent or nearly so. I am pretty sure that its own colour was grey.
