"Not written in French!" I exclaimed.

"No," replied Fortin solemnly, "it is written in Breton."

"But," I protested, "the Breton language was never written or printed in 1760."

"Except by priests," said the chemist.

"I have heard of but one priest who ever wrote the Breton language," I began.

Fortin stole a glance at my face.

"You mean—the Black Priest?" he asked.

I nodded.

Fortin opened his mouth to speak again, hesitated, and finally shut his teeth obstinately over the wheat stem that he was chewing.

"And the Black Priest?" I suggested encouragingly. But I knew it was useless; for it is easier to move the stars from their courses than to make an obstinate Breton talk. We walked on for a minute or two in silence.
