"And what thinkest thou, Rathos, is its foundation?" continued the prince.

"The Indian wise men say it is held up on the back of a huge tortoise; and our priests of Egypt that it floats in a vast ocean; while in Jaffa they teach that it floats on a boundless sea of fire. I know not, my lord prince. I leave knowledge of such wisdom to the great philosophers; and for my part am content to live upon our fair earth as long as the gods will, be it fire, or tortoise, or even though it stand on nothing, as the people in Persia hold that it does. But we are at the terrace-steps, my lord of Memphis!"

Here he bowed low, holding his hand to his heart, and left us to superintend the landing of the galley, at the porphyry staircase of the propylæum of the palace.

"Sesostris," said the prince to me, "has the idea occurred to you that this world may be a globe, suspended in subtle ether, and in diurnal revolution around the fixed sun?"

"Never, Remeses!" I cried, with a look of amazement at this bold and original thought. "It is impossible it should be so!"

"Nothing is impossible with the Author of creation!" said Remeses, with great solemnity. And, then, after an instant's pause, he added pleasantly—"On what does the sea of fire or the tortoise rest, my dear prince? Which theory is the most difficult to receive? But I have given astrology considerable attention, and if you will examine with me some observations and calculations that I have made, I think you will be with me in my novel opinion, that this earth may prove to be a sphere and in orbitual motion, with its seven planets, about the sun; its annual progress in its circuit giving us seasons, its diurnal motion night and day! But I see you stand perplexed and amazed. By and by you shall be initiated into the mysteries of my studies. Let us land!"

Farewell, dear mother. The great length of this letter renders it necessary that I should close it abruptly, but believe me ever

Your dutiful son,

Sesostris
