"Oh, I know what you mean," interrupted Christopher with quick intelligence. "Our kitchen clock has glass like that in the door. And meantime, while Connecticut was doing so much, what were the other states up to?" "Let me think a moment," replied the Scotchman, half closing his eyes. "Well, Rhode Island never furnished much aid along the line of clockmaking; her talents seemed to lie in the direction of spinning yarn, making thread, and weaving textiles. What clocks she needed were imported or made by hand by local silversmiths. Pennsylvania, however, contributed her part. David Rittenhouse of Philadelphia was an exceedingly skillful clockmaker who not only had to his credit many fine timepieces but also some very complicated and remarkable ones. Christopher Sower, too, was a Pennsylvania man not to be overlooked." "Christopher, eh?" the boy repeated. "Yes. There are some exceedingly distinguished Christophers in history, remember. You and Columbus are not the only ones," asserted McPhearson, with dancing eyes. "This Christopher Sower, now, could turn not alone his hand but his well-trained brain in a variety of worthy directions. To begin with, before he settled in Germantown he had taken a doctor's degree in an Old World medical university. Therefore after becoming established on his American farm he not only tilled the land but he doctored his neighbors. In addition he took up clockmaking, paper-making, and the printing of books. And as if these vocations, or avocations, did not keep him busy enough, he supplemented them by trying to improve the manufacture of cast-iron stoves. Even he himself, perhaps, felt it necessary to offer apology for dabbling in so many trades, for when he came to put his name on his clocks he spelled it _Souers_." The lad smiled. "Then there was also in Pennsylvania a friend of Benjamin Franklin's, Edward Duffield, who made good clocks. Meantime in New Hampshire both Timothy Chandler of Concord and Luther Smith of Keene were successfully plying the clockmaking trade and creating beautiful old clocks. But it was Massachusetts that was Connecticut's strong second." "And what was being done there?" McPhearson put down his drill. "Were I to begin that story," protested he, "I should have no lunch to-day and you would have none either. Maybe some other time--" "To-morrow?" suggested Christopher, who had no intention of allowing this prince of story-tellers to escape. "Why, yes--to-morrow--if you are still of the same mind, you shall hear the Massachusetts story." CHAPTER XVI WHAT MASSACHUSETTS CONTRIBUTED Mr. McPhearson had no chance to forget his promise even had he been so minded, for promptly the next morning, almost before his tools were laid out on his bench, Christopher presented himself, announcing with a mischievous smile: "To-day, you know, you are going to tell me the clock history of Massachusetts."
