respect for his materials and a conscientious appreciation of worthy craftsmanship, inherited by tradition from his mediæval predecessors and wholly apart from modern commercialism. Pride in his calling impelled him to the closest personal supervision and painstaking interest. He would be content with nothing short of the best. The amateur architects were no mere dabbling dilettanti, flirting with a polite and amiable penchant for architectural amenities. The best of them, and those that left the most impressive memorials of their talent and skill, were, as we shall presently see, busy men of large affairs and serious interests. They, as well as the master-carpenters, were thoroughly conversant with the best architectural books of the period and often had a fair showing of them on the shelves of their own libraries. More than one of them left standing orders with their London booksellers to send them, upon publication, such volumes as were most worth while. Another factor of their fitness is also to be reckoned. It was not unusual for them to possess training and experience as surveyors. Indeed, it was almost imperatively necessary for large landowners to have a knowledge of surveying in order to look properly after their interests. This training gave them an insight into the practice of making accurate measurements and draughting and the effect of such practical and exact education was not without its weight when they addressed themselves to designing buildings. One of the most striking and eminent figures among the eighteenth century amateur architects was the Honourable Andrew Hamilton, “the day-star of the American Revolution,” as Gouverneur Morris styled him, sometime Attorney-General of the Province of Pennsylvania, Provincial Councillor, Speaker of the Provincial Assembly from 1729 and for a number of successive years afterward and, above all, illustrious jurist and pleader, whose defence of Peter Zenger, the New York printer, in 1735, redounded to his fame both in England and throughout the Colonies. He was a man of exceptional and varied attainments, of catholic cultivation and outlook and endowed with remarkable elegancy of taste. Amid all the distractions and pressing concerns of an exacting legal and public career and the many demands involved in the successful management of a large private estate, he nevertheless found time to devote a good measure of attention to architectural diversions and left an enduring monument to his talents in that direction in the State House in Philadelphia.
