INSTRUCTIONS FROM THE WAR DEPARTMENT. 16 



You will then proceed to the G-ila river, and ascertaining carefully the practicability of a 

 road between the Pimaa villages and the mouth of the San Pedro, you will make the examina- 

 tions and purveys recommended in your report upon the route surveyed by you between the Gila 

 and the Rio Grande. 



Over this ground the geological examination and surveys will be particularly minute, 

 because it is especially important here to determine the practicability of obtaining a supply of 

 water ample for the uses of a railroad, either by artesian wells or by other modes. 



These duties being completed, should any further examinations or surveys be assigned to 

 you, instructions will be sent to Fort Fillmore. Should no further field duties be required of 

 you, you will discharge your party, dispose of your outfit to the best advantage, and proceed, 

 with your assistants, to this place and make out your report. 

 Very respectfully, your obedient servant, 



JEFFEESON DAVIS, 



Secretary of War, 

 Lieutenant John G. Parke, 



United States TopograpMcal Engineers, Washington, D. G.
