I spent some time searching PARES yesterday, and I came across a great Spanish Royal Treasury register for Havana from 1788. It is filed as “Mapa de la isla de Cuba y plano de las fortificaciones y torre faro del Morro de la Habana” (MP-SANTO_DOMINGO, 860) for the two images below that appear on the register. The fortresses of El Morro and San Carlos de la Cabaña — the latter completed in 1774 — figure in as fitting adornment as they sat at the entrance to the bay where goods (including enslaved men and women) entered and exited. The register lists the total number of ships entering and leaving for the year, in the categories military, mail, merchants, and foreign.
The register also totals all the sales of exports from Havana for the year, and it also includes total sources of other income, like what appear to be taxes on the sales of enslaved individuals. Exports from Havana comprise silver, gold, sugar, tobacco, honey, parrots, aguardiente, wood, leather, sweets, cotton, coconuts, wax, starch, rice, and cocoa, and the record also details amounts of each. The destinations are listed below. I was surprised to learn that enough parrots were exported from Havana in 1788 to be included: 53 in total.
