MERCHANT’S SCALE
$350
We have lately acquired a mid-nineteenth-century cast-iron balance-beam scale by Messrs. Stuart & Peterson of Philadelphia, one of the finest examples we have seen.
David Stuart and Richard Peterson operated the Spring Garden Iron Foundry on Willow Street above Thirteenth. Their business grew out of the foundry of William Penn Cresson, continuing under their names following his retirement in 1857.
From these works came stoves, kettles, pots, waffle irons, mills, and a considerable variety of household and commercial iron goods. An account published in 1868 describes an establishment employing about 300 workmen and consuming some 4,000 tons of iron each year. Counter scales are expressly named among its manufactures.
Such scales served the merchant’s counter, with goods upon one side and separate weights upon the other, the beam brought carefully to balance. A pound was expected to be a pound, and a merchant’s reputation depended upon it.
This example is remarkably similar in form and function to the nineteenth-century scales recovered from the steamboat Arabia, which sank in the Missouri River in 1856. These surviving pieces offer a wonderful glimpse into the everyday commerce of antebellum America.
