Correspondence between Nicholls and the High Commission for Grenada beginning by referencing a recent meeting concerning the future of the River Antoine Estate which Nicholls feels should be maintained " as an essential part of the history of Grenada. Further, it is a prime example of a water powered sugar mill, unique now in the whole of the Caribbean. It can be compared in importance with the huge Morgan Lewis Sugar Wind Mill in Barbados".
A visit from a television crew (Carlton Televsion) to the estate is arranged (December 1999), the crew extending a visit to film the completion and commissioning of the Morgan Lewis sugar mill. A previous visit by Nicholls to the River Antoine Estate with D.M.Simpson & Co Limited in 1997 is also referenced.
Arrangements are made for a visit to the estate by Cyril McCombe who Nicholls describes as "a consultant to our business in the UK and is a world wide authority on cast iron".
