CONCLUSION. 
It is my hope that this paper may serve to awaken interest in the 
classification and distribution of the non-Christian tribes of northern 
Luzon, so that the conclusions herein set forth may be verified or corrected 
and that we may obtain further information relative to the people of 
the several tribes. 
A law has been enacted for the government of the settlements of non- 
Christian tribes throughout the Philippine Islands, exclusive of the Moro 
Province where special legislation is in force, and in many of the prov- 
inces this law is rapidly being put into effect. A special provincial 
government act, providing a government particularly adapted to the 
needs of primitive people, is in effect in the Provinces of Nueva Vizcaya, 
Lepanto-Bontoc, and Benguet. 
Many of the Tingians of Abra and North and South Ilokos are already 
the equals in civilization of their Ilokano neighbors. Their old customs 
are rapidly being forgotten. On a recent occasion, when the members 
of two important Tingian families attempted to celebrate a wedding in 
the old-fashioned way, the party of bolo men which accompanied the 
bridegroom when he went to bring home the bride actually created alarm 
among the inhabitants of the settlement where that fair lady lived. 
Head-hunting has almost entirely ceased among the Bontoe Igorots 
and the I[fugaos. The Ilongots in 'Tayabas, Nueva Vizcaya, and Isabela 
are gradually being brought under the control of the governments of 
those provinces. Special governments will in the near future be estab- 
lished for the Kalingas and the wild Tingians of Apayao. 
It is therefore of great importance that the several tribes of northern 
Luzon should be studied carefully and thoroughly before customs which 
still prevail have been as completely forgotten as have the alphabets in 
which several of the civilized tribes formerly wrote their languages.
