Dutch language for ruled the middle colonies?

The Dutch language in its colonies never became as dominant and generally spoken as for instance the Engish language became in Britain's colonies. It was mostly spoken by the Dutch themselves living there and by the "educated" or ruling local people, either because they had attended Dutch-language schools and universities or because of very frequent contact with the Dutch.

Only in Surinam and the formerly Dutch Caribean islands - until very recently or even now part of the Dutch commonwealth - is Dutch still generally understood by the local people. Even there the spoken language is usually the local language.
