The procedure is as follows:  Late in the afternoon, all the necessary articles are brought to the house, then the mediums dance for a time to the music of the tongatong. Basi is served to the guests, and for an hour or more the spirits are summoned.  Next morning the kalangan is built, and two pigs are sacrificed beside it.  Their blood mixed with oil is offered to the spirits, and many acts, such as distributing the rice into ten dishes and then replacing it in the original container, the churning of sticks in the nose of a slaughtered animal and the like, are performed.  Spirits are summoned in the afternoon, and in the evening da-eng is danced.  On the third day new offerings are placed on the spirit shield and hanger; offerings are made at the new structure, numerous spirits appear, talk to and amuse the people, and finally da-eng is danced until late evening.

Following the ceremony, all members of the family are barred from work for about one month.  They may not eat the meat of the wild carabao, wild hog, beef, eels, nor may they use peppers in their food.  Wild fowl are barred for a period of one year.

Kalangan is much more widespread than either Tangpap or the Sayang ceremony, and this spirit structure is often found in villages, where the other great ceremonies are lacking.

Sayang.—­The greatest of all the ceremonies is the Sayang, the ability to celebrate which proclaims the family as one of wealth and importance.  In most cases the right is hereditary, but, as already indicated, a person may gain the privilege by giving, in order, and through a term of years, all the minor ceremonies.  In such circumstances Sayang follows Kalangan after a lapse of from four to eight years.  Otherwise the ceremony will be held about once in seven years, or when the spirit structure known as balaua is in need of repairs.

Originally this appears to have been a seventeen-day ceremony, as it still is in Manabo, Patok, Lagangilang, and neighboring villages, but in San Juan, Lagayan, Danglas, and some other settlements it now lasts only five or seven days.  However, even in those towns where it occupies full time, the first twelve days are preliminary in nature.

On the first day, the mediums go to the family dwelling and take great pains to see that all forbidden articles are removed, for wild ginger, peppers, shrimps, carabao flesh, and wild pork are tabooed, both during the ceremony and for the month following.  The next duty is to construct a woven bamboo frame known as talapitap on which the spirits are fed, and to prepare two sticks known as dakidak, one being a thin slender bamboo called bolo, the other a reed.  These are split at one end, so they will rattle when struck on the ground, and thus call the attention of the spirit for whom food is placed on the rack.

That evening a fire is built in the yard, and beside it the mediums dance da-eng alone.  Meanwhile a number of women gather in the yard and pound rice out of the straw.  This pounding of rice continues each evening of the first five days.  The first night they beat out ten bundles, the second, twenty, and so on, until they clean fifty on the fifth day.
