The instances when either the Spanish civil or ecclesiastical colonial authorities submitted enumerations of the mission establishments in Florida appear to have been infrequent and irregular. It is consequently somewhat surprising that two lists are available for the year 1675. The first of these to attract attention was the list incorporated in an undated letter written to the Queen of Spain by Bishop Gabriel Diaz Vara Calderon of Cuba, which was presented in translation by Lucy L. Wenhold (1936). The bishop paid an extensive pastoral visit to Florida in 1674-75, remaining for eight months, during which he appears to have visited Guale, Timuqua and Apalachee. His list has been the most useful of the enumerations heretofore available.
