What had seemed to be an overgrown mound rising like an island out of the dead level of the grassy sea now resolved itself into a collection of adobe walls, eaten and incrusted with shrubs and vines, that bore some resemblance to the usual uninhabited-looking exterior of a Spanish-American dwelling.  Apertures that might have been lance-shaped windows or only cracks and fissures in the walls were choked up with weeds and grass, and gave no passing glimpse of the interior.  Entering a ruinous corral they came to a second entrance, which proved to be the patio or courtyard.  The deserted wooden corridor, with beams, rafters, and floors whitened by the eternal sun and wind, contained a few withered leaves, dryly rotting skins, and thongs of leather, as if undisturbed by human care.  But among these scattered debris of former life and habitation there was no noisome or unclean suggestion of decay.  A faint, spiced odor of desiccation filled the bare walls.  There was no slime on stone or sun-dried brick.  In place of fungus or discolored moisture the dust of efflorescence whitened in the obscured corners.  The elements had picked clean the bones of the crumbling tenement ere they should finally absorb it.

A withered old peon woman, who in dress, complexion, and fibrous hair might have been an animated fragment of the debris, rustled out of a low vaulted passage and welcomed them with a feeble crepitation.  Following her into the dim interior Mrs. Tucker was surprised to find some slight attempt at comfort and even adornment in the two or three habitable apartments.  They were scrupulously clean and dry, two qualities which in her feminine eyes atoned for poverty of material.

“I could not send anything from San Bruno, the nearest village, without attracting attention,” explained Poindexter; “but if you can manage to picnic here for a day longer, I’ll get one of our Chinese friends here,” he pointed to the slough, “to bring over, for his return cargo from across the bay, any necessaries you may want.  There is no danger of his betraying you,” he added, with an ironical smile; “Chinamen and Indians are, by an ingenious provision of the statute of California, incapable of giving evidence against a white person.  You can trust your handmaiden perfectly—­even if she can’t trust you.  That is your sacred privilege under the constitution.  And now, as I expect to catch the up boat ten miles from hence, I must say ‘good-by’ until to-morrow night.  I hope to bring you then some more definite plans for the future.  The worst is over.”  He held her hand for a moment, and with a graver voice continued, “You have done it very well—­do you know—­very well!”
