To return to the invention of grates. As the consumption of coal increased, the transition from andirons to fire-grates composed of connected bars, was obvious and easy. The andirons formed the end-standards, which supported the grate itself, a sort of raised cradle. Besides these supports, the back-plate, cast from a model of carved-work (often with the arms of the family), was added; and generally under the lowest bar was a filigree ornament of bright metal, which, under the designation of a fret, still retains its place in modern stoves. Movable fireplaces of the above description may be met with about two hundred years old; for at this period, as the quotation of the time of James I. proves, implements for the fireplace were in use. A magnificent fireplace of the above description has been manufactured for St. George's Hall, in Windsor Castle, so as to harmonize with the architectural character of that noble apartment. Convenience soon suggested the fixing of fireplaces, which led to their being made with side-piers, or hobs, so as to fill the whole space within the chimney-jambs; till the snug cosy chimney-corner is only to be met with in farm-houses, where _dogs_ are used to this day. It would be tedious to follow the improvements in fireplaces from the first introduction of stoves, about the year 1780, to the present time: from straight unornamental bars and sides, to elegant curves, pedestal hobs, and fronts embellished with designs of great classic beauty. Indeed, in no branch of manufacture are the advantages of our enlarged acquaintance with the fine arts more evident than in the taste of ornaments displayed in the stove-grates of the present day. The tasteful display at the Great Exhibition of 1851 will doubtless be remembered by the reader. "Grates," says the Supplementary Report of the Juries on Design, "rank among the principal works in hardware to which ornamental design is applied, at least on the English side; and there by far the best specimens, both as to design and workmanship, are to be found: this was to be expected from the general necessity for warmth in our cold and variable climate; an Englishman's love for his fireside having passed into a proverb."
