"From the enemy," Rafael answered, with another laugh.
"I know that, of course," said Edith; "but Rome has had so many enemies that I can never keep the different ones separated in my mind."
Mrs. Sprague overheard the conversation, and said, "That is one reason why I brought you to Italy, Edith. I want you to understand all this Roman history, so that you will be able to pass your examinations when you return to school."
Rafael was interested to hear something about the American school examinations, and Edith told him of her troubles with history.
Then Rafael told of the difficulty he always had in remembering whether George Lincoln lived before Abraham Washington, or afterwards; and while Edith was explaining to him his mistake in the names, they arrived at one of the many olive-groves that dot the Tuscan hillsides.
"I think the vineyards are much prettier," said Edith. "But the twisted black trunks, and the gray branches of the olive trees are very picturesque," she added.
Boy-like, Rafael began at once to make friends with the farmer, and soon learned the whole process of crushing the oil from the ripe black fruit.
The farmer led them all to the sheds where the great stones were set up to crush the olives. He showed them just how the work was done, and then explained about the different grades of oil.
"We buy a great deal of your Italian oil in America," said Mrs. Sprague; and when Rafael had repeated this in Italian to the farmer, the man went into the house and soon returned with two bottles of his very best oil, which he presented to Edith and her mother.
"We Italians sell more oil than any other country," he said proudly to Rafael, "and we use a great quantity ourselves. It is much better than butter for cooking."
