Glass: A poem by Henry Schoolcraft
In the final years of the 1700s, a third generation family that was living in New York’s Hudson River Valley welcomed a new son, Henry Rowe Schoolcraft (1793-1864). They welcomed him into a newly formed country, brimming with promise and expectation, the United States of America. His father was the superintendant of a new window glass factory near Albany. The family boasted a long line of military men, but perhaps more importantly, a long line of adaptable, self-motivated, life-long learners and young Henry was no exception.
With the help of his father and like-minded family friends, Henry parlayed a rural education into private instruction in Latin, a premier collection of scientific books, and a museum quality mineral collection. In 1809, at the age of 16, he started a hand-written literary magazine called “The Cricket” in which he published short pieces of prose and poetry among a circle of friends. His time at Union College was cut short by the opportunity to manage a glass factory further west on the shores of Seneca Lake, near Geneva, New York.
Along with his father, Henry went on to become one of the most sought after glass factory guru’s in New England. In 1814, he was running the Vermont Glassworks on the shore of Lake Dunmore. He had set up an experimental furnace with Prof. Frederick Hall from the college in nearby Middlebury. Henry used the facility to research glass composition for a hefty book he was writing on the subject. Managing by day, experimenting by night, he still found time for his literary pursuits. It was here, in the autumn of 1814, that he composed a remarkable poem titled “Glass” in which he compares commonplace personalities of the early 19th century to the vitreous material of which he was so familiar.
Until now the poem has never been published beyond the first few stanzas. “Glass” runs for 268 lines of rhyming couplets in a lose meter. The handwritten manuscript is archived at the Library of Congress. It begins with an assessment of mankind: 
1 Mankind resemble glass; they are, like it, For use or fashion, show or service fit; Some bright and fair, some dull and more obscure, These prized as good, those, estimed poor; 5 To grace a kitchen, or a parlour made, As use is most consulted, or parade; But all as various; and eke they are, As frail, as brittle, and as keen a ware. Their bases differ, as our chemists say, 10 This made of sand, that fashioned out of clay Yet shall we, in both compositions find, Similitude in beauty, use and kind. To man, tis true some small objections lie In point of texture and transparency, 15 But though we grant him, in material blind, Yet lacks he not, transparency of mind And we no surer faults in each detect By rays of light, than rays of intellect. So nice the processes, the art requires, 20 So pure th’ ingredients, so intense the fires, Where tumours grow, where phthysic’s fitful breath, Forbodes the public faith, a sudden death. Felons, freckles, frightful fire warts, Are all disclosed as clear as limpid quartz. 25 His voice and pen are graced with equal skill, To lash, report, or advocate a bill. Speak without nostrums, clear his throat when lost, But ever loudest, when they shuffle most. Alike to him, the subject, time or stage, 30 Fierce to discuss, and ready to engage If finance—there Blaberius is at home If raising troops, he votes with general glum. In peace he’s noisy, but if wars involve’ He blasts the foe by one august “Resolve.” 35 Prate, prate, prate, prate! the error of the land, His voice, by every vulgar breeze is fanned Nor learn from Witherspoon his course to run, The simple cause, “to stop when he has done.” (Read full poem)
