tember 6; and my observations this evening venhed, in a very 

 satisfactory manner, the travelling rate assumed for the chronom- 

 eter 783. The longitude of camp of September 7, given by chro- 

 nometer, is 7^. 01m. 005. 5j that of this present camp, which is one 

 mile west of it, is Ih, Sin. 00s. Here, in addition to my usual obser- 

 vations for time and latitude, I took a set of lunar distances, with

Above this camp, there is on the river a considerable growth of 

 cotton-wood; among which are found some '^ signs" of beaver. The 

 plains and river bottoms were covered with much the same growth 

 as that heretofore noted; to which may be added an erythera, a 

 handsome little gentian-like plant, with deep rose-coloxed flowers, 

 and a solanum, a kind of wild potato, with narrow leaves, which 

 Dr. Torrey says'^is different from any in the United States. 



October 1. — To-day, for the first time for six days, I was able 

 to rise from my bed without assistance. The air w^as elastic, and 

 fragrant wath the perfumes of the wild sage from the adjacent 

 hills. Every thing was, in truth, couleur de rose; for the sun 

 beamed out bright and red, infusing the same tint over the land- 

 scape, till near meridian. I crossed to Tome, in search of some 

 non-complying guides! We recrossed at Tome, and measured the 

 section of the river. Accordingly, we found the Rio Grande del 

 Norte, many hundred miles from its source,

This section is about the same as at San Felippe and Santo Do- 

 add the section of a stream of water carried 



mingo 



If to it we 



off by two large zequias, each nine feet by two, we shall have 

 an estimate of the volume of water discharged by this famous 

 river, for 150 miles, through the most populous and fertile part ot 



its valley. 



Below Tome, for a few miles, the valley widens, the soil iTa- 

 proves, and the cultivation is superior to any other part, particu- 

 larly that of the rancherias around the pleasant little village of 



Belen. 



October 2.— This morning, we passed the pretty church in. the 



village of Sabinal, after which the settlements became very fe^ 

 and tar between. We encamped opposite La Lloya, at the beD*I 

 of the river Del Norte, where the low sand hills on either side seers 

 to unite and shut up the valley. 



We received a message from the major domo of the neighboriuS 

 rancheria, cautioning us to we watchful of our animals, that fortV 

 of the Navajoes had passed the river last night. The incursions ot 

 th^se Indians have prevented the settlement and cultivation of tb^^ 

 part of the country.
