"Not he, chevalier," I answered, "come on," and turning to the left we trotted up the Ripetta. I knew Jacopo too well not to feel sure he would catch us up again, and that he had some definite object, which was not desertion, in going off as he did. Yet I could not help being put out by his action, and resolved to give him the rough side of my tongue when he came back. We were almost up to the Porta del Popolo when he returned, coming with a loose rein, and as he drew in with the troop, I turned round.

"How now, sirrah! What does this prank mean?"

"Pardon, excellency, it was no bee that stung me. I suddenly remembered that we should have little luck on our journey if I did not pay her dues to our Lady of the Fountain."

"Our Lady of the Fountain?"

"Excellency, the fountain of Trevi. Does not your worship know that no one should leave Rome without dropping a piece of silver in her basin?"

"Indeed! I was not aware of it, but remember--no more sudden thoughts like this."

"Excellency!"

I said no more, and passing through the ruined Porta del Popolo where the breaches made by Charles' cannon were still unrepaired, we took the Flaminian Way, and galloped down the road almost in darkness owing to the shadows thrown by the high walls on each side of us. We re-crossed the Tiber at the Ponte Molle, and, still keeping the Via Flaminia, turned our horses' heads in the direction of Castel Nuovo.

It was a wonderful night. There was no breeze, except that which we made ourselves as we galloped along. Not a cloud obscured the sky, arching deep blue over the yellow moon, now in her full strength. To the left the beacon fire from the top of the Tor di Vergara blazed like a red star low down in the horizon, and before us was the white road stretching in a ghostly line, its ups and downs accentuated by the moonlight. The Tiber lay to our right, but owing to the undulation of the ground we could not see it, although an occasional flash showed us where the waters reflected the rays of the moon.

Not the best horse in the world could keep up the pace we were going for long, and I was old enough soldier to know that our speed must be regulated by the slowest beast if we wanted to reach in full strength, so I slackened rein to a walk and gave the animals a rest.
