File No. 312.51/108.
Vice-Consul Blocker to the Secretary of State.
I have refused to certify invoices of coal entered for export to the United States by Constitutionalists authorities because coal was taken from Rio Esconclido and Agujita coal mines owned by French and American citizens. The mines were confiscated by Constitutionalists on May 19, 1914. Out of 20,000 shares Rio Escondido, French and American citizens hold more than eighty per cent of stock.
