London 25 February 1776
[Extract]
The Count de Guines was authorised to send to America M. de Bon~ vouloir who was granted two hundred guineas by the Court as a remuneration for his services. Last September, this officer received one year's pay in advance, as shown by his receipt. He has not been heard from yet. 2 The Count de Guines agreed with him that he would send his letters to M. Guit lebert, Consul in charge, of to M. Martin Froment, assistant to the mayor in Calais who would give them to M.Grandin responsible to forward them to the King's Ambassador. Because of the fact it was impossible to entrust a cqde to M:.de Bonvouloir wh~ m1.ght be searched and whose coded letters, furthermore, could not come on English ships, it was decided that all his letters would be addressed to a Company in Anvers, that they would treat commercial subjects and that secret information would be written with milk. This writing can only be seen with the help of a red-hot scoop.
