“We call it London,” murmured Betty. But Lucius did not seem to hear her. “Then I suppose it was a good thing for the British to be conquered?” she inquired.

The boy laughed. “Without doubt. They were savages when we came, and we’ve taught them everything. From us they’ve learnt how to till the land,”—he nodded towards a field. “Those are British labourers working there now. They’ve learnt how to make roads after our famous Roman plan. You can see one of our roads from this corner of the terrace. And how to build houses and ships, and work in metal and do a thousand other things. Some of them have grown rich, and have been educated, so that they are as good scholars now as we are. Already Londinium is a famous port to which foreign merchants come bringing riches. My father says it will some day be a great city, equal to any city in the world.”

“It has become a great city!” exclaimed Betty to herself, remembering the London she knew. It was sad to think that if she had spoken aloud, the boy would not have understood her, and she hastened to ask another question.

“Are these British people Christians?”

“Oh yes!” said Lucius. “Ever since we became Christians ourselves, you know. Of course when my ancestors first came here, they themselves were pagans. They worshipped gods and goddesses like Apollo and Venus. But that’s a hundred years ago. Now Londinium is a Christian city, and we’re teaching the British to be Christians also. It’s rather difficult though, because a great many of them cling to their old gods. Still, most of them at least call themselves Christians.”

“Do you like living in this country—in Britain?” asked Betty after a moment.

“Oh yes. It’s my home. I was born here. But I should like to go to Rome—the city from which my great-grandfather came when he settled here, and built this villa. Perhaps I shall, some day,” he went on dreamily. “My father often says we may have to go back to our own land. There are troubles there. The barbarians are growing stronger and stronger, and some day Rome will need all the fighting men she can get to defend her.”

“But the British will have no one to defend them if you go,” objected Betty.

Lucius shrugged his shoulders. “No, poor things. Their state will be very desperate if enemies come to invade them when we are gone....”

Betty scarcely listened to the end of his sentence, for she had made a discovery which interested her too much. On his third finger Lucius wore the very ring which not long ago had been in her own hand! But before she could exclaim, Betty found herself standing once more upon London Bridge, with her Godmother beside her, and strangely enough Godmother was repeating almost the very words the boy had just uttered!
