After them comes another group of actors clothed in ceremonial kilts and wearing helmet masks. They are called the "Stone War Club _Kachinas_" and with them are two men dressed as women; one, representing the Spider Woman, dances before the fire with graceful movements of the arms and body to the sound of singing and the beat of a drum. At the close of the dance she distributes seeds of corn, melons, and useful plants. The fourth act is that of the Maiden Corn Grinders. First, two masked men bring down the ladder bundles containing two grinding slabs and grinding stones and arrange them on the floor. After them come two masked girls in elaborate ceremonial attire, followed in a little while by a line of masked dancers who form the chorus. At a signal the chorus begins to sing and posture while the maids grind corn in time with the song. They then leave the mills and dance in the middle of the room with graceful movements, pointing at the audience with ears of corn, while the bearers of the mill stones put pinches of meal in the mouths of the spectators. The fifth act is somewhat like the first, except that there are two huge snakes, and several of the actors as chorus, with knobs of mud on their masks, wrestle with the snakes in a most realistic fashion and afford great entertainment. After this act another set of performers gives a more remarkable serpent drama. Back of the field of corn on the floor are seen two large pottery vases, and, as if by magic, the covers of the vases fly back, and from them two serpents emerge, swoop down and overthrow the corn hills, struggle with each other and perform many gyrations, then withdraw into the vases. In the dim light of the kiva fire the cords by which the serpents are manipulated cannot be seen, and the realism of the act is wonderful. In other years the acts are even more startling, as when masked men wrestle with serpents which seem to try to coil about their victims. The actor thrusts one arm in the body of the snake in order to give these movements, while a false arm is tied to his shoulder. Sometimes also the corn-maid grinders are represented by joined figures surrounded by a framework. They are made to bend backward and forward and grind corn on small _metates_. At times they raise one hand and rub meal on their faces, like the Hopi corn grinders in daily life, while above them on the framework two birds carved from wood and painted are made to walk back and forth. On the day of the public dance the corn maids attended by many masked _Kachinas_ grind in the dance plaza.
