It is said the Aztec calendar was carved in 1479, and its inauguration was celebrated with fearful sacrifices, but the conquering Cortes had it pulled down, and it remained buried until lowering the grade of the ancient pavement in 1790, when it was built in the southwestern tower of the cathedral. There it remained until about a year ago, when it was removed to the museum, where it now occupies a prominent position. The Sad Indian, a statue so-called because it was unearthed on a street of that name, is a jolly-looking fellow, and compels one's admiration, despite his broad nose and ugly features. So far I have heard no blood-curdling tales connected with him, but the wiseacre shakes his head solemnly and replies: "Hundreds of human beings were sacrificed on his account, but the history has escaped my memory." Meanwhile, the old fellow sits there with folded hands and a comical expression on his face, thinking, probably, of the duties which he once performed, which were, undoubtedly, holding a lamp or a flag, as the hole through the folded hands and between the feet directly beneath proves. It is quite interesting to roam around and examine this broad face and that slim one, from those of mammoth size to ones the size of one's hand. We grow to like the queer objects which certainly formed some part in the lives of those strange people who lived and died centuries before us. In one corner locked up in a cell by itself is the coach of Maximilian and Carlotta. It is one of the finest in the world, and is similar in construction and finish to that used on State occasions by the Czar of Russia. The coach was a present to Carlotta from Napoleon II. It is so fine that it is difficult to give a description of it. The royal coat of arms is on every available spot, on the doors and above, wrought in gold, and embroidered in gold on the crimson velvet which covers the driver's seat. The entire coach is gold and crimson except for the inside, which is heavy white silk, cords, fringe and tassels of the same. Gold cherubs the size of a three-month-old baby finish each corner. The carriage was drawn by eight pure white horses or the same number of coal black ones, and as it swept down the grand passes to superb Chapultepec, holding its royal owners, it must have been a sight fit for kings. But it stands to-day a silent memento of a murdered young emperor and a blighted empress. All the men employed at the museum are disabled soldiers, and it speaks well of the government to give them this employment. They seem to rightly belong in among this queer stuff, for it would take half a dozen of them to make a whole man. The museum is open only from ten to twelve, and is free to all.
