In the Puerto del Dado of the Chiricahui range, instead of the 60 feet cutting, heavy embank-

WATER AND FUEL. 
This region, then, presents great advantages in the construction of a railroad at small cost, so 
far as the grading and preparing the road-bed for the superstructure is concerned; but in two 
elements for cheap construction and working of a road, it is now very deficient, viz: water and 
fuel. For the first, the distances apart of the permanent streams affording large supplies, in 
the dryest season of the year, and therefore under the most unfavorable circumstances, are as 
follows : 
From the Rio Grande to the Rio Mimbres, 71 miles. 
From the Rio Grande to Cook’s Spring, 61 miles, it being 53 miles from the Rio Grande, and 
8 miles north of the track.
