Indigo in New Spain: a tahona, a sowing tube and a memoir written to answer the charge that Spain only vegetates

A first-person memoir printed in a Mexican compilation of 1855 under the head ANIL, by the eighteenth-century editor who had published a translated treatise on indigo in his periodical of 1772. It records two Mexican improvements to a Caribbean industry - a tannery mill that cut the cost of hulling indigo seed from sixteen or twenty pesos to two or three reales, and a sowing tube - and states its purpose: to answer those who say the Spanish nation only vegetates.
