Usage examples of "spring-house".
Yet there remains to the Wedge an Unseen World, beyond Resolution, of transactions never recorded, upon Creeksides and beneath Hedges, in Barns, Lofts, and Spring-houses, in the long Summer Maize fields, where one may be lost within minutes of entering the vast unforgiving Thickets of Stalks, indeed, all manner of secret paths and clearings and alcoves are defin'd, push'd over or stamp'd into being, roofless as Ruins, for but a few fugitive weeks of lull before autumnal responsibilities come again looming.
