The next unit, _mano_, has in a similar manner been twisted out of its original sense, and in counting breadfruit is made to serve for 8000.

In the northern, or Nukuhivan Islands, the decimal-quaternary system is more regular.

It is in the counting of breadfruit only,[202] 4 breadfruits = 1 pona = 4.
10 pona = 1 toha = 40.
10 toha = 1 au = 400.
10 au = 1 mano = 4000.
10 mano = 1 tini = 40,000.
10 tini = 1 tufa = 400,000.
10 tufa = 1 pohi = 4,000,000.
In the Hawaiian dialect this scale is, with slight modification, the universal scale, used not only in counting breadfruit, but any other objects as well.

The result is a complete decimal-quaternary system, such as is found nowhere else in the world except in this and a few of the neighbouring dialects of the Pacific.

This scale, which is almost identical with the Nukuhivan, is[203] 4 units = 1 ha or tauna = 4.
10 tauna = 1 tanaha = 40.
10 tanaha = 1 lau = 400.
10 lau = 1 mano = 4000.
10 mano = 1 tini = 40,000.
10 tini = 1 lehu = 400,000.
The quaternary element thus introduced has modified the entire structure of the Hawaiian number system.
