lowing me
to accept. My thanks are also due the various officers and officials
of the Insular Government who placed me under obligations by their
hospitality and other courtesies and by the never-failing patience
with which they received and answered my many questions. To my
friend Colonel J.G. Harbord, United States Army, Assistant Director
of Constabulary, I am beholden for instructions sent out in advance
of the journey to the various Constabulary posts on the itinerary,
directing them to offer me every opportunity to accomplish the purpose
of my trip. Except where otherwise indicated, the illustrations
are from photographs taken either by Mr. Worcester himself, or else
under his direction. Some of these, as shown, were lent to me by the
National Geographic Magazine of Washington, and others by the Bureau
of Insular Affairs of the War Department. My best thanks are due and
given in each case. Dr. Heiser was kind enough to let me have a few
photographs taken by him. To Lieutenant P.D. Glassford, 2d Regiment
of Field Artillery, I am indebted for the map of Northern Luzon and
for one or two other illustrations copied from Jenks' "The Bontoc
Igorot"; to Father Malumbres, of the Dominican Monastery in Manila,
for information relating to Padre Villaverde and for the portrait of
that missionary; it is to be regretted that this portrait should be
so unsatisfactory, but it is the only one available. The frontispiece
is by Mr. Julian Miller, who has lived in the Igorot country, and
whose drawing is from life.

country.

It is to be regretted that the people of the United States should in
general show so little interest in the Philippine Islands. This lack
of interest may be due to lack of knowledge; if this be so, then it
is the duty of those better informed to do all that lies in their
power to develop the interest now regrettably absent. Be this as it
may, it is assumed here that most of our people do not know that a
very large fraction of the inhabitants of the Philippines consists
of the so-called wild men, and that of these the greatest group or
collection is found in the mountains of Northern Luzon.

These mountaineers or highlanders constitute perhaps, all other
things being equal, as interesting a body of uncivilized people a
