Towns to the east of Bontoc, such as Tukukan, Sakasakan, and Tinglayan, grow tobacco which passes westward in trade from town to town nearly, if not quite, through the Province of Lepanto.  It doubles its value for about every day of its journey, or at each trading.

Samoki pottery and the salt of Mayinit offer as good illustrations as there are of the Igorot barter.  A dozen loads of earthenware, from sixty to seventy-five pots, leave Samoki at one time destined for a single pueblo (see Pl.  CXXIII).  The Samoki pot is made for a definite trade.  Titipan uses many of a certain kind for her commercial basi and the potters say that they make pots somewhat different for about all the two dozen pueblos supplied by them.  The potter has learned the art of catering to the trade.  There is not only a variety of forms made but the capacity of the fangas ranges from about one quart to ten and twelve gallons, and each variety is made to satisfy a particular and known demand.  Samoki ware seldom passes as far east as Sakasakan, only four or five hours distant, because similar ware is made in Bituagan, which supplies not only Sakasakan but the pueblos farther up the river.

There are supposed to be between 280 and 290 families dwelling in Bontoc, and, at a conservative estimate, each family has eight fangas.  Each dwelling of a widow has several, so it is a fair estimate to say there are 300 dwellings in the pueblo, having a total of 2,400 fangas.  Samoki has about 1,200 fangas in daily use.  The estimated population of the several towns that use Samoki pots is 24,000.

There is about one pot per individual in daily use in Bontoc and Samoki, and this estimate is probably fair for the other pueblos.  So about 24,000 Samoki pots are daily in use, and this number is maintained by the potters.  Igorot claim the average life of a fanga of Samoki is one year or less, so the pueblo must sell at least 24,000 pots per annum.  At the average price of 5 centavos about the equivalent of 1,200 pesos come to the pueblo annually from this art, or about 40 pesos for each of the thirty potters, whether or not she works at her art.  A few years ago, during a severe state of feud, Samoki pots increased in value about thirty-fold; it is said that the potters purchased carabao for ten large ollas each.  To-day the large ollas are worth about 2 pesos, and carabaos are valued at from 40 to 70 pesos.

Mayinit salt passes in barter to about as many pueblos as do the Samoki pots, but while the pots go westward to the border of the Bontoc culture area the salt passes far beyond the eastern border, being bartered from pueblo to pueblo.  It does not go far north of Mayinit, or go at all regularly far west, because those pueblos within access of the China Sea coast buy salt evaporated from sea water by the Ilokano of Candon.  In April at two different times twelve loads of Candon salt passed eastward through Bontoc on the shoulders of Tukukan men, but during the rainy season and the busy planting and harvesting months Mayinit salt supplies a large demand.
