The nobles listened with respectful attention. It seemed to them probable enough that a supernatural personage might convoy himself vast distances through the air, but that he could not burden himself with mortal appliances--if, indeed, such things were the work of merely mortal men.

"I could bring with me," Roger went on, "but one small specimen of the metal most used in that distant country."

Then the merchants advanced, and handed to Roger his knife, which they had purchased of the cazique of Tabasco in exchange for two accomplished slaves, and he presented it to the nobles.

"You see it is a metal of extraordinary hardness. Swords made of it will cut through a man's head to the chin. No arrows or spears will penetrate armor made of it. It can be beaten into all shapes, when hot. The weapons of which I spoke to you are constructed of it, and it is now used in the arts, in manufacture, and for domestic purposes, as well as for armor and weapons. So common is it that, as you see, the handle is made only of rough horn; which shows you that it is such a one as is commonly used, and is prized but little. It may be that such a metal is found in your country, though as yet you know it not; for in its natural state it is but a stone like others, although greater in weight; and if so, I may be permitted, some day, to instruct you in the methods of working it."

The nobles were greatly impressed with this speech. Quetzalcoatl had instructed the Mexicans in all the arts that they possessed, and this hint that their visitor might bestow upon them the knowledge of this new, and most valuable metal, seemed a fresh proof of his relationship to the White God, whose return had been so long expected and longed for.

They now begged him to enter the city, and a party of their slaves took up the gifts, and ranged themselves behind him. The Mexican troops fell in on either side, and prevented the crowd from pressing in upon them; and then, accompanied by the two nobles, and followed immediately by the merchants, Roger headed the procession as it again set forward.

As he entered the town, Roger saw that it was vastly in advance of Tabasco. The walls were of stone, strong and massive. The streets were wide and straight, bordered by well-built houses with flat roofs, upon which great numbers of people were assembled. These uttered cries of welcome as he came along, and threw down wreaths of flowers.

The Aztec governor, with a strong guard of soldiers, met them in a large square in the center of the town; and in the name of the Emperor Montezuma welcomed Roger, and presented him with gifts of even greater value than those sent by the King of Tezcuco, saying that his master hoped that he would pay a visit to his capital, as well as to that of the neighboring sovereign.

Roger replied suitably, and the procession then took its way to a large house that had been assigned to the visitor. Here a banquet was served in grand style, the governor and the two ambassadors, alone, taking their seats with him. The meal was served up on golden dishes, and pulque was handed round, in goblets of the same metal, by white-robed slaves.

Strains of music rose in the air, the performers being stationed in an adjoining apartment. The music was unlike anything Roger had ever before heard, and seemed to him to be of a plaintive nature.
