Fenders of brass or iron were generally used with these grates, a small one placed close to the fire to prevent the ashes from falling over the hearth, and a larger one arranged around the entire fireplace. Although hob grates were popular in Northern houses, they were much more frequently used in the South. Tiles were little used in America until the hob grate era, when they seem to have come into vogue. They were used to surround both hob grates and Franklin stoves. Some of them showed decorations of religious subjects, while others, like a set in a Salem house, told in pictures the story of Æsop's Fables. There is a tiled fireplace still in existence in the Saltonstall-Howe house at Haverhill, Massachusetts, a dwelling originally owned by Dr. Saltonstall, the first medical practitioner in the city. This fireplace, in the dining-room, shows a double row of tiles, depicting a series of Scriptural events, and it is equipped with a fender of ancient hammered brass, a family heirloom. The date of the fireplace can be definitely determined without knowledge of the time of the erection of the house from the fact of the absence of a mantel above. Another similar fireplace adorned with quaint Dutch tiles is shown in the Pickering house living-room. Like the Saltonstall one, this fireplace has a beautiful, ancient fender of brass and a pair of bellows that were made by Rev. Theophilus Pickering, a preacher in Essex, Massachusetts, who succeeded the Rev. John Wise. The first hob grate ever placed in a Salem home is to be seen in the Waters house on Washington Square. It is topped with one of McIntyre's famous mantels, showing that the original fireplace was brought down to be used with the grate. Elias Hasket Derby, one of Salem's most famous merchants, had a beautiful estate where Market Square now stands. The house, which was a marvel of elegance, stood in the center of the square, surrounded with terraced gardens that swept to the water's edge. After his death the house was too large and elegant to be kept up, and it was torn down and the land sold. The timbers of the house, the wood carving, and mantels were purchased by Salem house owners, one hob grate finding its way to the old Henry K. Oliver house on Federal Street. This dwelling, which was built in 1802 by Captain Samuel Cook for his daughter, who married Mr. Oliver, shows old-time fireplaces in many rooms, one of brass being found in the parlor. This was the first of its kind ever placed in a Salem home, and it has a grate, on either side of which are brass pillars about three feet in height, with brass balls on top. A brass band extends from pillar to pillar below the grate, and the fender is also of brass. The mantel above is elegantly carved, and came from the Elias Hasket Derby mansion.
