the chief passive agent in the pederastic ceremonies which form so important a part in the performances. These take place in the spring of every year, and are conducted with the utmost secrecy, as regards the non-Indian part of the population. For the making of a _mujerado_ one of the most virile men is selected, and the act of masturbation is performed upon him many times every day; at the same time he is made to ride almost continuously on horseback. The genital organs are thus brought, at first, into a state of extreme erethism, so that the motion of the horse is sufficient to produce a discharge of seminal fluid, while at the same time the pressure of the body on the animal's back--for the riding is done without a saddle--interferes with their proper nutrition. It eventually happens that, though an orgasm may be caused, emissions can no longer be effected, even upon the most intense degree of excitation. Finally, the accomplishment of an orgasm becomes impossible; in the meantime the penis and testicles begin to shrink, and in time reach their lowest plane of degradation. But the most decided changes are at the same time going on, little by little, in the instincts and proclivities of the subject. He loses his taste for those sports and occupations in which he formerly indulged, his courage disappears, and he becomes timid to such an extent that, if he is a man occupying a prominent place in the council of the pueblo, he is at once relieved of all power and responsibility, and his influence is at an end. If he is married his wife and children pass from under his control,--whether, however, through his wish or theirs, or by the orders of the council, I could not ascertain. They certainly become no more to him than other women and children of the pueblo." Hammond examined one of these men, who had, as he himself informed him, formerly possessed a large penis and testicles "grande como huevos,"--as large as eggs. The penis was in its flaccid state and about an inch and a half in length, with the glans about the size of a thimble, which it very much resembled in shape. The glandular structure of the testicles had disappeared; they were atrophied, little besides connective tissue remaining. He examined another _mujerado_ in the pueblo of Acoma, who had been so made when at about the age of twenty-six. The penis was not more than an inch in length and about the diameter of the little finger, and of the testicles there was apparently nothing left but a little connective tissue. Both of these men had high-pitched voices.
