Charles C. Marsh to Mes, July 6, 1871

Gentlemen: Returning from Rome I find yours of the 1st instant, and will immediately bring the subject to the attention of the Italian government.

Before I can take any specific steps, however, I must have definite information as to–

• The nationality of the owners of the petroleum shipped.
• The time of shipment.
• The nationality of the vessel by which the cargoes are shipped.
• The quality and quantity of the article, and the., amount of duty levied upon it.

I can interfere in no case unless it is susceptible of proof that the petroleum is exported solely on account of shippers of American nationality.
