term "ghost," although he has a definite function ascribed
to the rather fiendish "nightmare" -- that of sitting heavily on the
breast and stomach of a sleeper.

The ta'-ko, the soul of the living man, is a faithful servant of man,
and, though accustomed to leave the body at times, it brings to the
person the knowledge of the unseen spirit life in which the Igorot
constantly lives. In other words, the people, especially the old men,
dream dreams and see visions, and these form the meshes of the net
which has caught here and there stray or apparently related facts
from which the Igorot constructs much of his belief in spirit life.

The immediate surroundings of every Igorot group is the home of the
a-ni'-to of departed members of the group, though they do not usually
live in the pueblo itself. Their dwellings, sementeras, pigs, chickens,
and carabaos -- in fact, all the possessions the living had -- are
scattered about in spirit form, in the neighboring mountains. There the
great hosts of the a-ni'-to live, and there they reproduce, in spirit
form, the life of the living. They construct and live in dwellings,
build and cultivate sementeras, marry, and even bear children;
and eventually, some of them, at least, die or change their forms
again. The Igorot do not say how long an a-ni'-to lives, and they
have not tried to answer the question of the final disposition of
a-ni'-to, but in various ceremonials a-ni'-to of several generations
of ancestors are invited to the family feast, so the Igorot does not
believe that the a-ni'-to ceases, as an a-ni'-to, in what would be
the lifetime of a person.

When an a-ni'-to dies or changes its form it may become a snake --
and the Igorot never kills a snake, except if it bothers about his
dwelling; or it may become a rock -- there is one such a-ni'-to rock
on the mountain horizon north of Bontoc; but the most common form for
a dead a-ni'-to to take is li'-fa, the phosphorescent glow in the
dead wood of the mountains. Why or how these various changes occur
the Igorot does not understand.

In many respects the dreamer has seen the a-ni'-to world in great
detail. He has seen that a-ni'-to are rich or poor, old or young,
as were the persons at death, and yet there is progression, such
as birth, marriage, old age, and death. Each man seems to know in
what part of the mountains his a-ni'-to will dwell, because some one
of his ancestors is known to inhabit a particular place, and where
