Location of the Fields 



The region described in this paper lies along the Gulf coast of the 

 Republic of Mexico in the States of Tamaulipas, Vera Cruz, and San Luis 

 Potosi. The author visited this district during November and December, 

 1911, and was afforded every facility for travel by the officers of the Mexi- 

 can Petroleum Company, Limited, of Delaware, on rail, steamer, and 

 horse' through several hundred miles of jungle, seeing and examining a 

 large number of petroleum developments and seepages. For a portion 

 of the trip the party was accompanied by Sefior Ezequie] Ordonez, the 

 distinguished Mexican geologist and- Fellow- of this Society, whose inti- 

 mate knowledge of Mexican geology, and especially of the structural con- 

 ditions in the petroleum fields of Mexico, proved of great value and 

 assistance in the cursory study undertaken. The Locations of the prin- 

 cipal oil developments along the Gulf coast of northeastern Mexico, as 

 well as many of the seepages, are shown on this blue-print map, fur 

 nished the writer through the courtesy of Herbert (i. Wvlie, of Ebano,
