Grandfathers' Clocks: Their Making and Their Makers in Lancaster County
GRANDFATHERS' CLOCKS: THEIR MAKING AND THEIR MAKERS IN LANCASTER COUNTY, Whilst Lancaster county is not the first or only home of the so-called "Grandfathers' Clock," yet the extent and the excellence of the clock industry in this type of clocks entitle our county to claim special distinction as one of the most noted centres of its production. I, therefore, feel the story of it specially worthy of an enduring place in our annals, and it is with pleasure •and patriotic enthusiasm that I devote the time and research necessary to do justice to the subject that so closely touches the dearest traditions of our old county's social life and surroundings. These old clocks, first bought and used by the forefathers of many of us, have stood for a century or more in hundreds of our homes, faithfully and tirelessly marking the flight of time, in annual succession, for four genera- tions of our sires from the cradle to the grave. Well do they recall to memory and imagination the joys and sorrows, the hopes and disappointments, the successes and failures, the ioves and the hates, hours of anguish, thrills of happiness and pleasure, that have gone into and went to make up the lives of the lines of humanity that have scanned their faces to know and note the minutes and the hours that have made the years of each succeeding life. There is a strong human element in the existence of all such clocks, and that human appeal to our thoughts and memories is doubly intensified when we know that we are looking upon a clock that has thus spanned the lives of our very own flesh and blood from the beginning. -

Grandfathers' Clocks: Their Making and Their Makers in Lancaster County * By D. F. MAGEE, ESQ. Whilst Lancaster County is not the first or only home of the so-called "Grandfathers' Clock," yet the extent and the excellence of the clock industry in this type of clocks entitle our county to claim special distinction as one of the most noted centres of its production.

In the Stores of the British Museum Are Three Exquisite Springs, Made in the Late 1820S and 1830S, to Regulate the Most Precise Timepieces in the World
1 Riotous assemblage and the materials of regulation Abstract: In the stores of the British Museum are three exquisite springs, made in the late 1820s and 1830s, to regulate the most precise timepieces in the world. Barely the thickness of a hair, they are exquisite because they are made entirely of glass. Combining new documentary evidence, funded by the Antiquarian Horological Society, with the first technical analysis of the springs, undertaken in collaboration with the British Museum, the research presented here uncovers their extraordinary significance to the global extension of nineteenth century capitalism through the repeal of the Corn Laws. In the 1830s and 1840s the Astronomer Royal, George Biddell Airy; the Hydrographer to the Admiralty, Francis Beaufort; and the Prime Minister, Sir Robert Peel, collaborated with the virtuoso chronometer-maker, Edward John Dent, to mobilize the specificity of particular forms of glass, the salience of the Glass Tax, and the significance of state standards, as means to reform. These protagonists looked to glass and its properties to transform the fiscal military state into an exquisitely regulated machine with the appearance of automation and the gloss of the free-trade liberal ideal. Surprising but significant connexions, linking Newcastle mobs to tales of Cinderella and the use of small change, demonstrate why historians must attend to materials and how such attention exposes claims to knowledge, the interests behind such claims, and the impact they have had upon the design and architecture of the modern world. Through the pivotal role of glass, this paper reveals the entangled emergence of state and market capitalism, and how the means of production was transformed in vitreous proportions. -
