that will be no trouble to keep and won't expect to be fed. One that
has no fleas and is neat in his habits. One that will obey me when I
speak to him. In short, a good dog," said the wizard.

"Such a dog is hard to find," returned the glass-blower, who was
busy making a blue glass flower pot with a pink glass rosebush in
it, having green glass leaves and yellow glass roses.

The wizard watched him thoughtfully.

"Why cannot you blow me a dog out of glass?" he asked, presently.

"I can," declared the glass-blower; "but it would not bark at
people, you know."

"Oh, I'll fix that easily enough," replied the other. "If I could
not make a glass dog bark I would be a mighty poor wizard."

"Very well; if you can use a glass dog I'll be pleased to blow one
for you. Only, you must pay for my work."

"Certainly," agreed the wizard. "But I have none of that horrid
stuff you call money. You must take some of my wares in exchange."

The glass-blower considered the matter for a moment.

"Could you give me something to cure my rheumatism?" he asked.

"Oh, yes; easily."
