"Fuerte River Bridge." File No. 331.1-973-(F). From More bridge construction stuff. This one notable because the cost of doing so (approx. $473,000 U.S.) was to be offset by the Mexican government's allowing the SPdeM to retain the 10% tax on gross receipts and apply it to the notes owed the government. This gained the SP de Mex about $680,000 in 1928 (as it was estimated in May of that year by projecting forward). Sproule (SP de México President) notes in letter of 5/16/28 to SP Chairman H.W. DeForest in N.Y. that "Secretary of Treasury of Mexico has definitely assured Mr. Titcomb that there will be no questions raised about our retaining 10% Gross Receipt Taxes hereafter." Perhaps ten pieces; several blueprints
