Mexico) and Salina Cruz, and short 

 railroads radiate from the port of 

 Progreso, Yucatan. The principal ports 

 of the east coast, Tampico, Vera Cruz 

 and Progreso, are reached by regular 

 steamers from New York, New Orleans 

 and other cities, and from Tampico 

 and Vera Cruz there is rail connection 

 with the interior. On the west coast 

 there are numerous ports visited by 

 coastwise steamers, some of which have 

 railroad connections. Among the prin- 

 cipal ports that may be mentioned are 

 Guaymas, La Paz, Mazatlan, San Bias, 

 Manzanillo, Acapulco, Salina Cruz, 

 and Tapachula. 



Visitors to Mexico should be provided 

 with passports. Collectors of birds or 

 mammals, especially, should inform 

 themselves concerning Federal and local 

 laws and regulations affecting shooting 

 and the taking of such material. Let- 

 ters of introduction to officials and 

 others should be secured whenever 

 possible as they are of gr.eat value in 

 preventing misunderstanding. Dis- 

 turbed political conditions may make 

 certain regions unsafe. Mexican 

 officials are usually very courteous and 

 inclined to be helpful when approached 

 by properly accredited individuals, 

 as are the people in general except the 

 Indians of some remote sections who 

 look with suspicion upon all visitors 

 whose motives they can not readily 

 understand.
