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

 ment, and side-cutting, and tho grades used by Lieut. Parke, 46 feet the greatest, we may use 

 temporarily the surface grades, which are as follows : 



21 miles, 48 feet per mile, ascending.

In the gap in the ridge east of the Valle de Sauz, instead of the cutting of 60 feet, or tunnelling, 

 and a grade of 90 feet, or less, by increasing distance, we may use, temporarily, the surface 

 grades, which are as follows :

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.
