The boy put out his hand shyly.

The eyes that met his were of the kindliest blue; and the face they illumined was ruddy, wholesome, and alert.

Instantly Theo decided that since Mr. Croyden himself could not be his guide he had at least provided a very pleasant substitute.

"Theo wants to see everything there is to be seen, Jack," continued Mr. Croyden. "Tote him all about and answer all his questions; and above all be thorough, even if you do not cover very much ground during the morning. I want the processes carefully explained, for this boy may be a china-maker himself some day. If I do not join you before noontime bring all that is left of him back to the conservatory so I can take him to lunch."

Mr. Marwood laughed, and so did Theo.

Then they passed out.

"Good luck!" called Mr. Croyden after them as he turned to take up his mail.
