“The only restrictions placed upon you in this matter are: 1. The enemies of my country are not for any consideration whatever to have the benefits of these improvements. On the contrary, on making them known to others, you are to make them known in confidence and with a clause in the agreement especially providing against publicity and stipulating that the plan shall not be made known to any Yankee or his government. 2. I had already offered to H. I. H. Grand Duke Constantine, as a token of acknowledgment for his great kindness and friendly consideration shown me and mine, when this war broke out, to place all these my discoveries and improvements at his feet and for the use of his government. I have referred him to you as my confidant and friend who is fully prepared to carry out my plans in all their details, or who will explain them in confidence to any person he may appoint. You are to make no charge, therefore, for imparting this information, at his request, and should he or his government think proper to offer me an honorarium, it is not to be shared by you. 3. My friend, Captain M. Jansen of the Dutch Navy who resides at Delft, has assisted me in a part of these experiments. We are as brothers. All that I have done is known to him and he has the authority to use the information acquired for his own government, provided he may be personally benefited thereby. The restriction here is, that should you deem it worth while to bring the subject before the Dutch government you will first confer with Captain Jansen and shape your course accordingly. Should you effect a negotiation there, please turn over to him my share of the Dutch grant. 4. I restrict you also as to Mexico. Leave that to me. Should, however, any negotiation be entered into with that government, I shall refer the authorities to you for the articles such as wire, etc. required.
