"Tell me, is your trade hard?"

"Hard! Well, it is not for anyone. It is the hardest work there is. It is a trade which the world cannot dispense with. No one can get on without a blacksmith. Believe me when I say it. The Emperor of Rome had a councillor whose name was Vulcant and it was he who invented the blacksmith's art. And you ask if it is difficult!"

"Yes, but one could learn it," said Sten, who felt more amused than convinced.

"Learn it? No, sir, one cannot."

"But you have learnt it," insisted Sten.

"I! With me it is another matter," answered the blacksmith, contemplating the bottom of his mug.

"Well, why cannot it be another matter with me also?" objected Sten.

"Show me your fists, if you please, sir."

Sten laid two small white hands on the table.

The smith grinned. "They are no use. Look at mine." He took the pewter pot in a giant's grasp and squeezed it till it became as slender as an hour-glass.
