y is connected with it.

The shaman's song sounded very different from the songs I had heard
among the Tarahumares. As his seat was high, he had to maintain a
stooping position all the time he played. The dancers, men and women,
made much noise by stamping their fiat soles vigorously on the ground,
as they moved in double column around the fire and the shaman, in a
kind of two-step-walk forward. They danced in a direction against the
apparent movement of the sun, the men leading, the women following. I
noticed that the step of the women was slightly different from that
of the men, inasmuch as they lifted themselves on their toes at each
step. At times the columns would suddenly stop and make the same
kind of movements backward for a little while, with the same small
jumps or skips as when walking forward. After a few seconds they
would again go forward. These movements are directed by the leader,
the man who dances first.

Both men and women wore flowers, the former fastening them to their
straw hats, the latter in their hair with the stem behind the ear. The
flowers were apparently selected according to individual taste, but
the kind I saw most frequently was a white blossom called _corpus_,
the delicious fragrance of which I noticed every time the women
danced by. Two boys had a peculiar kind of white flower fastened with
a handkerchief tied around their heads. It is called _clavillinos_,
and looks like thick, white hair. The shaman wore a narrow hair-ribbon,
but no flower. Around their ankles the men had wound strings of dried
empty pods of a certain palm, which made a rattling noise during the
dancing. Five times during the night, ears of corn and plumes were
brought from the altar, and then the men always removed their hats. The
women wore veils (_rebosos_), but it is considered improper for them
to use sandals on such occasions; these are worn only by the men.

There were five pauses made in the course of the night, and, to
prepare the people for them, the shaman each time began to strike
more slowly. The dancers continued until they arrived in front of the
altar, where they commenced to jump up and down on the same spot,
but with increasing rapidity, until the music stopped, when they
separated and lay down.

Those who did not take any part in the dancing were lying around the
various fires, the number of the dancers changing with the different
songs, according to the degree of enthusiasm among the people. Ma
