We now bade adieu to Igára and Adó, and entered the I’gbo territories.
Immediately adjoining Abaji to the southward is Inám, the people of which, though an I’gbo race, formerly paid tribute to the Attá [of Igára], and afterwards to [King] Obi [of Abó].
A branch here joins the river, known, as the Inám river, and the Inám country is nearly a day’s canoe-journey up this stream. The people trade chiefly at Asabá and Onitshá, in country cloths, com, yams, fowls, &c.
Next to Inám, but nearer the river, is Nsúgbe or Isúgbe, founded upwards of twenty years ago by a man from Abó, who, having killed one of his wives, had to leave that place.
The dialect spoken is Abó, and tribute was formerly paid to Obi ; but, since his death, to nobody. Their town, also named Nsúgbe, is on the north side of the Inám river, but the district extends on both sides. The people deal in similar articles to those of Inám, but trade principally at Onitshá.
Inám and Nsúgbe are supplied with muskets mostly from Iddá, to which place they are brought from Abó. At the time of our visit the value of an ordinary musket at Iddá was from 10,000 to 12,000′ cowries, and at Abó, from 8000 to 9000 cowries ; the value of a flint at Abó was 20 cowries.
Below Walker Island, on the right bank, stands a small village belonging to Asabá, and named A’param-U’gboru.
The language is Abó, and its market is visited by traders from Igára, and from Inám.
