Note 11 — Chapter I

“The dyer’s lichen was first exported from the islands of the Archipelago to Venice, Genoa, France, and England, for the use of the dyers. Towards the commencement of the last century it was discovered in the Canary Islands, and was soon placed among the regalia of the Spanish crown. This excited the attention of the Portuguese, who collected it without restriction in the Cape de Verd Islands, Madeira, Porto Santo, and the Azores. In the year 1730, the Jesuits asked of King John V. the privilege of collecting the Hervinha secca; but the crown took the advantage into its own hands, and farmed the right of collecting it. At a later period the lichen was ceded to the mercantile company of Gram Pará and Maranhâo; and, lastly, in the year 1790, the government again took this branch of commerce under its own care, because it had declined considerably under the bad management of the company. At present the exportation is small; but more considerable, however, from the Cape de Verd Isles.” (See I.
