g are good because they bring rain, yet if they
are exceedingly violent he becomes afraid and tries to stop them by
burning deer's bones, which, he says, are always efficacious.

The mathematical knowledge of the Negritos is naturally small. They
count on their fingers and toes, beginning always with the thumb and
great toe. If the things they are counting are more than twenty they
go through the process again, but never repeat the fingers without
first counting the toes. To add they use rice or small stones. They
have no weights or measures except those of the civilized natives, but
usually compare things to be measured with some known object. Distance
is estimated by the time taken to walk it, but they have no conception
of hours. It may take from sunrise until the sun is directly overhead
to go from a certain rancheria to another, but if asked the number of
hours the Negrito is as likely to say three or eight as six. They have
no division of time by weeks or months, but have periods corresponding
to the phase of the moon, to which they give names. The new moon
is called "bay'-un bu'-an," the full moon "da-a'-na bu'-an," and
the waning moon "may-a'-mo-a bu'-an." They determine years by the
planting or harvesting season. Yet no record of years is kept, and
memory seldom goes back beyond the last season. Hence the Negritos
have no idea of age. They know that they are old enough to have
children or grandchildren, and that is as far as their knowledge of
age goes. To count days ahead they tie knots in a string of bejuco
and each day cut off one knot.

In regard to units of value they are familiar with the peso and other
coins of the Philippines and have vague ideas as to their value. But
one meets persistently the word "tael" in their estimate of the value
of things. A tael is 5 pesos. If asked how much he paid for his wife a
mail may say "luampo fact." Where they got this Chinese term I do not
attempt to say, unless it points to very remote commercial relations
with the Chinese, a thine, which seems incredible. [24]

The Negritos have developed to a high degree a sense of the dramatic,
and they can relate a tale graphically, becoming so interested in their
account as to seem to for get their surroundings. For instance, a head
man was giving me one night an account of their marriage ceremony. He
went through all the motions necessary to depict various actions,
talking faster and louder as if warming up to his theme, his
