'"What we saw last night was a trading-station," said Allo. "Nothing but a trading-station."
'"I do not like lies on an empty stomach," said Pertinax. "I suppose" (he had eyes like an eagle's)--"I suppose _that_ is a trading-station also?" He pointed to a smoke far off on a hill-top, ascending in what we call the Picts' Call:--Puff--double-puff: double-puff--puff! They make it by raising and dropping a wet hide on a fire.
'"No," said Allo, pushing the platter back into the bag. "That is for you and me. Your fate is fixed. Come."
'We came. When one takes Heather, one must obey one's Pict--but that wretched smoke was twenty miles distant, well over on the East coast, and the day was as hot as a bath.
'"Whatever happens," said Allo, while our ponies grunted along, "I want you to remember me."
'"I shall not forget," said Pertinax. "You have cheated me out of my breakfast."
"What is a handful of crushed oats to a Roman?" he said. Then he laughed his laugh that was not a laugh.
"What would _you_ do if _you_ were a handful of oats being crushed between the upper and lower stones of a mill?"
'"I'm Pertinax, not a riddle-guesser," said Pertinax.
'"You're a fool," said Allo. "Your Gods and my Gods are threatened by strange Gods, and all you can do is to laugh."
'"I pray the Gods that may be true," he said. "But I ask you again not to forget me."
'We climbed the last hot hill and looked out on the eastern sea, three or four miles off. There was a small sailing-galley of the North Gaul pattern at anchor, her landing-plank down and her sail half up; and below us, alone in a hollow, holding his pony, sat Maximus, Emperor of Britain! He was dressed like a hunter, and he leaned on his little stick; but I knew that back as far as I could see it, and I told Pertinax.
'"You're madder than Allo!" he said. "It must be the sun!"
'Maximus never stirred till we stood before him. Then he looked me up and down, and said: "Hungry again? It seems to be my destiny to feed you whenever we meet. I have food here. Allo shall cook it."
'"No," said Allo. "A Prince in his own land does not wait on wandering Emperors. I feed my two children without asking your leave." He began to blow up the ashes.
'"I was wrong," said Pertinax. "We are all mad. Speak up, O Madman called Emperor!"
