At the back of the castle is the Military Academy, or West Point of Mexico. Three hundred cadets, with their officers, are housed here. The school is kept in the best of order, and when the cadets finish their seven years' course they are well prepared for future duties. The cadets belong to the best families and number a lot of handsome men. The stairway which divides, or rather connects, the two buildings is an odd yet pretty structure. It is built in an arch to the height of ten feet. Then starting out in opposite directions are two other arches, which connect the buildings. These arches--the stairway, of course--have no supports whatever, and one is almost afraid they may cave in with their weight. When they were finished some one remarked to the builder, "They will fall down if one man mounts them." "Bring a regiment and put on them, and I guarantee they stand," replied the builder. This was done, and they were found to be as firm as a mountain. They are certainly one of the prettiest pieces of architectural work ever executed. In the library of the academy are oil paintings of the cadets who fell in defense of Chapultepec. They were handsome young boys, and a fine marble shaft, inclosed with an iron fence at the foot of the hill, is erected in commemoration of their heroic deed. The prettiest boy of the lot, with sunny locks and blue eyes, folded the flag, for which he was fighting, to his breast, and stood with a smile on his face while his enemies cut him into pieces. He was but thirteen years old. His picture occupies a prominent place, and beneath it stands the flag, dyed a dark crimson with his heart's blood. The cadets keep those little heroes' memories green. Every morning they place wreaths of flowers on the monument as they march on their way to the meadows below to drill.
