son grows more and more arid becoming, a few miles beyond 

 Gualan, a desert region in which tree cacti flourish. Gualan 

 is eighty miles from Puerto Barrios and 420 feet above sea- 

 level. El Rancho, at an elevation of 901 feet, is nearly one 

 hundred and thirty miles from Puerto Barrios. We arrived 

 at Gualan about nine P. M. 



January n, 1905. Vegetation about Gualan becoming dry 

 and leafless, a small leguminous tree, resembling a peach in 

 habit of growth and color of flowers, is in full bloom. Maize 

 on the hill sides has been harvested and not replanted. 

 Smaller streams have shrunken in volume and native gardens 

 are being irrigated. About half a mile above station at Gualan 

 the railroad crosses a tributary of the Motagua known as the 

 Gualan River. On this date the Gualan River has an average 

 width of about one hundred feet. The stream is divided by

 stream to form the Gualan River, and in irrigated fields and 

 along ditches adjacent to this stream, as far as a village named 

 Sing Sing, situated on the Honduras road. 



January 14, 1905.- Same territory as Januarj^ i3th. 



January 15, 1905. In fields and along the Gualan River,
