"Suppose, then, since you are so docile and accommodating, we leap to somewhere near the year 1650, when the inspiration to attach the pallets of the escapement to the pendulum rod, thereby making the escapement horizontal, came almost simultaneously to an Englishman named Harris and a Dutchman named Huyghens. These, together with the later ideas of anchor escapement evolved by Graham, put clocks, within the span of a few years, on an almost modern basis. Other improvements such as using steel springs in place of weights and the perfecting of movements have of course been made since; but this period covers the time of most vital improvement in the art of clockmaking. At this time, too, some of the finest of old English watches and clocks were made. Thomas Tompion, sometimes called the father of English clock making, took his place at the head of these, and to this day beautiful old clocks that are still in service testify to his skillful workmanship." "What sort of clocks did he make?" inquired Christopher with interest. "Just about every design of the period--bracket clocks similar to those of Richard Parsons'; long-case, or what we call grandfather, clocks; even brass clocks with projecting dials; and in addition, the greater part of the finest watches turned out at this time were of his making. There were few who could equal him. Possibly Daniel Quare and Joseph Knibb made clocks as good, but they certainly made no better. Were you to visit Buckingham Palace or Windsor Castle, you would find there wonderful chiming grandfather clocks made by this same Thomas Tompion. They are genuine treasures and would bring almost any price. So remember, in journeying through the world, if you ever run across a clock or a watch made by Thomas Tompion, you are looking at a very fine bit of handicraft." "I'm afraid I never shall," Christopher shook his head. "One never can tell where his path through life will take him," McPhearson said. "For example, I never expected my wanderings would lead me from Glasgow to America. Nor, probably, did Stuart dream when he woke up to-day that his morning ride in a Fifth Avenue bus would land him in jail. So you must not despair of seeing London and some of Thomas Tompion's clocks. Moreover, should you go there, I hope you will hunt up in Westminster Abbey the grave of this famous man." "Was he buried at Westminster? Why, I thought only kings, queens, poets, and great people had places there," Christopher ventured, a trifle incredulous.
