Esp. Volume 2 Pages 519, 616 And 866.) But The Salt Was Extremely Impure, Grey, Mixed With Earthy Particles, And Surcharged With Muriate And Sulphate Of Magnesia.

Since the province of Cumana has become dependent on the intendancia of Caracas, the sale of salt is under

The control of the excise; and the fanega, which the Guayquerias sold at half a piastre, costs a piastre and a half.* (* The fanega of salt is sold to those Indians and fishermen who do not pay the duties (derechos reales), at Punta Araya for six, at Cumana for eight reals. The prices to the other tribes are, at Araya ten, at Cumana twelve reals.) This augmentation of price is slightly compensated by greater purity of the salt, and by the facility with which the fishermen and farmers can procure it in abundance during the whole year. The salt-works of Araya yielded to the treasury, in 1799, a clear income of eight thousand piastres.

Considered as a branch of industry the salt produced here is not of any great importance, but the nature of the soil which contains the salt-marshes is well worthy of attention. In order to obtain a clear idea of the geological connection existing between this muriatiferous soil and the rocks of more ancient formation, we shall take a general view of the neighbouring mountains of Cumana, and those of the peninsula of Araya, and the island of Margareta.
