Memória sobre a plantação dos algodões / e sua exportação sobre a decadencia da lavoura de mandiocas, no termo da villa de Camamú, Comarca dos Ilhéos, Governo da Bahia

The author presents practical observations on cultivating cotton and analyzes the decline of manioc in the Camamú district of Bahia, combining local geographic description with discussion of soil, climate, and hydrology. He contrasts transplanted European plants with native species, argues that climate more strongly shapes vegetation than soil, and explains how irregular rainfall and coastal versus interior conditions influence crop success. The text identifies inland areas and river routes suitable for cotton, assesses risks to yield and post‑harvest preservation, and offers agronomic and export-minded recommendations intended to improve regional cultivation and trade prospects.
