The owner Johan Lorentz Carstens supported a missionary called Martin who worked for the Moravian Church (Herrnhuter brothers – whose founder and high superintendent was Count Nikolas Ludwig von Zinzendorf).
Two of his slaves, Mingo and Andreas, became Martin’s first native helpers, and when the missionary caught the tropical fever, Mrs. Carstens took care of him and nursed him through his illness.
Then it was allowed to cool while the dirt that rises to the surface was skimmed off using a long shank of foam.
All impurities, together with the non-crystallized sugar, dirty molasses (syrup) and other unusable by-products were carefully stored, as it was used later for the Rum distillation.
The flat fields at Mosquito Bay, where Carstens had his plantation, are covered by the concrete runways of Harry S. Truman Airport.
The islands massive development in connection with the circumstances that cultivation of sugar stopped at an early stage, has resulted in far fewer ruins here that on St. Croix.
