I may here observe, that their money currency does not consist of the precious metals, which are too common among them for that purpose.

The smaller coins in ordinary use are manufactured from a peculiar fossil shell, the comparatively scarce remnant of some very early deluge, or other convulsion of nature, by which a species has become extinct.

It is minute, and flat as an oyster, and takes a jewel-like polish.

This coinage circulates among all the tribes of the Vril-ya.

Their larger transactions are carried on much like ours, by bills of exchange, and thin metallic plates which answer the purpose of our bank-notes.
Let me take this occasion of adding that the taxation among the tribe I became acquainted with was very considerable, compared with the amount of population.
