7. Represents the statue of Chac-Mool uncovered at the depth of 8 meters. At the sides are seen the frame-work “of trunks of trees of 2 to 2-1/2 inches in diameter, secured with vines.” The inclined plane on which it was drawn to the surface is visible, as are some of the ten Indian laborers, in working costume. 8. The statue has now been drawn to the upper part of the inclined plane. The ropes of habin bark are attached to the figure. Near the sculptured slabs at the right, already shown in 3, 5 and 6, Mrs. Le Plongeon appears seated. 9. Shows the capstan that served to raise the statue, the size of which is apparent by comparison with the figure of the Indian near it. 10. Apparently the same locality as 4. The method of moving the statue over the fragments of sculpture and other impediments is shown. 11. The size and appearance of the statue, “half as large again as the natural size,” is here distinctly pictured, together with Dr. Le Plongeon standing in the rear of his discovery. The head-dress, trappings and sandals are clearly defined. 12. The statue is seen on the rude wagon on which it had been transported to Pisté, a distance of 3 or 4 miles. In the rear is seen the stone church of Pisté, surmounted by a cross, described in _Charnay’s Cités et Ruines Américaines_, page 336, and by Dr. Le Plongeon, in the _Mexican Memorial_. Nearly all the small towns have similar Churches, built from the ruins of Indian buildings. It is probable that some of the choicest works of art, too large to be easily destroyed, were put out of sight in the construction of these edifices by the fanatical conquerors of the 16th century. NOTE. The numbers of the pictures do not agree with those in the _Mexican Memorial_.] It appears that Dr. Le Plongeon, on his arrival in Yucatan, in 1873, first visited Uxmal, where he made explorations and took photographs. He then prepared himself to undertake the more difficult and dangerous visit to Chichen-Itza. While there, the discovery of the statue, Chac-Mool, was made, and it was excavated in the manner described by the discoverer in the last pages of the _Mexican Memorial_. Dr. Le Plongeon had formed a design of sending the statue and certain bas-reliefs, together with plans and photographs, to the Centennial Exhibition, and had prepared these articles for removal, when a sudden revolution occasioned the disarming of his Indian laborers, who for some time had served for a protection, and all further operations were suspended, as longer residence in that exposed region without arms was sheer madness. It was at that time that Dr. Le Plongeon wrote the following Memorial to the Mexican President, Senor Don Sebastian Lerdo de Tejada, which is given nearly entire, as it makes a statement of his claims and wishes, and contains very important information concerning the discovery of the statue, and gives an idea of his method of exploration.
