There are other mounds near the pyramids, besides the Micaotli. Two sides of the Pyramid of the Sun are surrounded by them; and there are two squares of mounds at equal distances, north and south of it, besides innumerable scattered hillocks. There are some sculptured blocks of stone lying near the pyramids, and inside the smaller one is buried what appears to be a female bust of colossal size, with the mouth like an oval ring, so common in Mexican sculptures. The same abundance of ancient remains that we found here characterizes the neighbourhood of all the Mexican monuments in the country, with one curious exception. Burkart declares that in the vicinity of the extensive remains of temples known as _Los Edificios_, near Zacatecas, no traces of pottery or of obsidian were to be found. Before going away, we held a solemn market of antiquities. We sat cross-legged on the ground, and the Indian women and children brought us many curious articles in clay and obsidian, which we bought and deposited in two great bags of aloe-fibre which our man carried at his saddle-bow. Among the articles we bought were various pipes or whistles of pottery, _pitos_, as they are called in Spanish, and just as we were mounting our horses to ride off, a lad ran to the top of one of the mounds, and blew on one of these pipes a long dismal note that could be heard a mile off. Our friends had filled our heads so full of robbers and ambushes, that we made sure it was a signal for some one who was waiting for us, and the more so as the boy ran off as soon as he had blown his blast; and when we looked round for the people whose antiquities we had been buying, they had all disappeared. But nothing came of it, and we got safely back to Tezcuco. As usual, we spent a capital evening, and separated late. The owner of the glass-works, who had been spending the evening with us, had an adventure on his road home. He was peaceably riding along, when two men rushed out from behind the corner of the street, and shouted “_alto ahí_!” (halte-là). He thought they were robbers, and started at a gallop. His hat flew off, and the men sent two bullets singing past his head, which sent him on quicker than ever, till he reached his house. There he got his pistols, and came back armed to the teeth to fetch the hat, which lay where it had fallen. The supposed robbers turned out, on enquiry next day, to have been national guards, patrolling the street; but certainly their proceedings were rather questionable.
