He worked at this himself, drenched with sweat, tugging at the stones, while Caliban and a mason from the village set them and threw sand over the wet plaster (the method which we decided must have been adopted by the builder of the cottage), and I, too weak yet to help in this giant's play, criticised the effect from a rowboat outside the lagoon, telegraphing messages by means of a handkerchief code. Often Margarita would come with me, embroidering placidly in the bow of the boat, under her wide hat. She detested sewing, and refused utterly to learn any form of it, to Miss Jencks's sorrow, but had invented a charming fashion of embroidery for herself and worked fitfully at tiny white butterflies in the corner of my cambric handkerchiefs--the one and only form this art of hers ever took. It became a sort of emblem and insignia of her, and Whistler, who began coming to them, I think, the year after that, or the next, made much of this fanciful bond between them. It was she who worked the black butterfly upon the lapel of his evening coat which created such a sensation in Paris one season. Once while shooting in the Rockies with Upgrove, six or eight years ago, I pulled out an old buckskin tobacco pouch, turned it hopefully inside out in the search for a stray thimbleful, and discovered in a corner of the lining a faded yellow silk butterfly, all unknown to me till then! She must have worked it surreptitiously, like a mischievous, affectionate child; and as I held it in my hands, and stared at the graceful absurd thing, the lonely camp faded before me; the sizzling bacon, the rough shelter, the whistling guide, slipped back into some inconsequential past, and I lay again on the sun-warmed rocks, watching a yellow-headed toddler prying damp pebbles from the beach, to pile them later in her tolerant lap. Oh, Margarita! Oh, the happy days! CHAPTER XXI HESTER PRYNNE'S SECRET I remember so well the morning of the great discovery. It was one of those damp, rainy, grey days when happy people can afford to realise contentment indoors, and we were a very comfortable group indeed: Margarita sorting music, Roger drawing plans for a new chimney, Miss Jencks shaking a coral rattle for the delectation of the tiny Mary, who lay in her shallow basket under the lee of the great spinning-wheel, and I hugging the fire and watching them. I considered Roger's reforms in the matter of chimneys too thorough-going for the slender frame of the house and told him so.
