"Well, there are several excellent reasons," Mr. Croyden replied. "One is that the ware shows traces of a book-binding tool. Book-binders, you know, use many small instruments to decorate or tool their leather. This faience was a ware of natural cream-colored clay, and upon it was tooled a flat design the hollows of which were filled in with darker clays that were afterward covered with a lead glaze. Infinite care and pains had evidently been expended upon each piece of the ware, such pains that it must have taken much time to complete even a single article. No manufacturer could have afforded to do this, and therefore the inference had been drawn that the pottery was made purely for pleasure by some one who had an abundance of leisure. Perhaps this very Bernard, the librarian, who may have become interested in the art as a recreation, and done the work in his idle hours."

"What a funny thing to do as a pastime!" exclaimed Theo.

"No stranger than that now many persons take up metal work, wood-carving, or other of the so-called arts and crafts for diversion."

"I suppose not," admitted Theo thoughtfully.

"It certainly is possible such a thing might have happened even so long ago as the time when the Henri Deux ware was made. History offers us no aid in solving the puzzle, so we can only find an answer as best we may. The ware, however, is unique, and there is no mistaking it. Some of it bears the monogram of King Henry II, and that accounts for the name by which the product passes. There are authorities that assert the H does not stand for the king's name, but for Helene, mistress of the Château d'Orion; others declare the king's monogram was used merely to fix the date when the pottery was made. Hence you will find some china collectors calling it Henri Deux ware, and others speaking of it as Faience d'Orion; while still others refer to it as Saint Porchaire. When examining it it is interesting to notice how much finer the later pieces are than the earlier ones. Evidently Bernard, if Bernard it was, improved a great deal with practice."

It was obvious that Mr. Croyden had no more to say about the elusive Bernard, for he came to an abrupt stop.

Theo waited a second, and then remarked suggestively:

"And Palissy?"

"Palissy? Oh, he was another matter altogether. What did you learn about him when you were at school?"

"Not much, I'm afraid," responded Theo with a shrug. "At least I do not remember much of it now. The teacher told us that one day Palissy saw an enameled cup of Saracen workmanship and that he was so anxious to discover how the glaze on it was made that he worked years experimenting; he even chopped up all his furniture as fuel for his furnaces."
