Orizaba and Cordoba. 



Orizaba (4,000 feet) and Cordoba (2,700 feet) on the line of the 

 Mexican Railroad (Ferro-Carril Mexicano) can be treated of

 Vera Cruz and 181 miles from the City of Mexico. The town lies

 town is composed, for the most part, of low houses with red-tiled 

 roofs; it is crossed by two small streams, and by the little river 

 Orizaba (through a rocky ravine filled with tropical plants), all of 

 which unite near by in the River Blanco, which plunges over a pre- 

 cipice in a cascade in the Rincon Grande. The valley alone was 

 explored botanically during the short time at the disposal of the 

 writer. The several ravines were followed through the town to the

 were investigated for the plants that might be in flower. Most of 

 the larger trees were found to be loaded down with epiphytes, 

 orchids, tillandsias, and mistletoe with several ferns. To one who
