What wonder that with such constant use the boy's strength was daily increasing until he was becoming a veritable young giant? With no small satisfaction he beheld the muscles of his arms tighten and stand out; and when he swung his axe and brought down a sturdy sapling it was with a glow of pleasure that he heard it crash to the ground. Certainly there were compensations in hard work! Moreover was not every French boy who was too young to serve in the army being a man at home? He was but doing what all his friends were. Nevertheless the thought of a holiday did fill him with anticipation. To get into something beside his workaday clothes, and to mingle for an entire day amid new scenes, to say nothing of seeing Henri St. Amant again—what a delight it would be!

Madame Bretton caught a reflection from his happiness and that nothing should be left undone that should enhance the joy of her son's outing she broke over her rules of strict frugality and packed a luncheon for him, to which she added a few of the little luxuries which for a long time the family had denied themselves.

And so in high spirits Pierre set forth for Pont-de-Saint-Michel. How familiar every step of the journey seemed this time! And how good it was to find Henri St. Amant awaiting him in the office of the Gaspard mills!

"I have been working over time all the last week, so they are letting me have this morning to show you about the throwing mills," he explained, his eyes shining into Pierre's still brighter ones. "And at noontime when we have finished our round of the factory we can go down by the river, and while we eat our luncheon we can talk together. Therefore suppose we do not waste precious moments in visiting now, for we shall scarcely have time to see all I want to show you before the noon whistle blows."

Accordingly Pierre's box of lunch was stowed away in Henri's locker, and speeding across the little bridge that connected the filature with the throwing mills, the two boys entered the great factories.

"Before we go another step there is one question I must ask you," said Pierre, stopping in the doorway. "I want you to tell me why the twisting of raw silk into thread is called throwing."

"I'll try to explain it as well as I can, Pierre," answered Henri. "Maybe you have stuck me on the very first question you've asked," he added smiling. "All I know is that the operation of twisting, or throwsting, the fibres of raw silk has come to be abbreviated into throwing. The workmen are known as silk throwsters. It is an old trade. At the beginning of the sixteenth century there were throwing mills at Bologna which were so good that it is from them our present day machinery has been copied and perfected. Usually the work is done on commission—the manager, or throwster, receiving orders from weaving mills for exactly the sort of thread they wish to use."

"Isn't it all alike?"

"No, indeed! It varies in size according to the number of threads in a strand, and the number of twists and turns to the inch. Some materials that are to be woven require heavy, loosely twisted thread; others, that which is fine and tightly twisted. And in addition to these differences some thread is not made from pure silk, or even from silk of the best quality; raw silk which is imperfect can just as well be used for certain purposes, or silk that is twisted with a strand of cotton or some other filling. There are a great many qualities and kinds of thread and each one has to be specified."

Pierre opened his eyes.
