Now if this is the case, it is obvious that a trade in these two articles might be set up between the two countries, and would be very advantageous to both. We will suppose that the islanders send their matting to San Francisco, and that in the first instance they obtain for it the full value of matting, measured in boots, that prevails in that country. This, as we have seen, is at the rate of five yards of matting for one pair of boots, or eight times as high a value as the matting obtains in the island.
