mouth of tbe Nutria, and the latter stream through nearly all its course, 

 have hue but narrow valleys, and the Piedra has other small patches of 

 land near its head. The Eio do los Piuos has a narrow valley extending, 

 with short breaks to its continuity, far up into the mountains. The 

 Animas and Florida have similar valleys. That of the former stream is 

 particularly fine, spreadiug out in Animas Park to one of the finest 

 mountain valleys in the State. The La Plata can water a strip of valley 

 land 20 miles long by at least 2 in width. The arable land on the 

 Mancos is mainly in a patch at the immediate foot of the La Plata 

 Mountains ; but, in addition, there is a very narrow belt along the river, 

 for 25 or 30 miles above its mouth. 



The other branches of the San Juan in the State, the McElmo and 

 Hovenweep, are dry the greater part of the year from head to mouth, 

 and their courses are in close canon.
