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.
