the Andes are ivided into three chains the first and most 
eastern, rises between Pozuzu and Mima, between the Eio 
HuaUaga, and the Ivio Pachitea, a tributary of the Ucayali- 
the second, or central, is between the Huallaga! S the 
Maranon ; the third, or western, between the Upper 
Maranon and the coast of Truxillo and Paida. The eastern 
Cham IS a small lateral branch which lovveils into a raim^of 
hiUs: Its direction is first N.N.E., bordering the Pampas 
del Sacramento, afterwards it turns W.If.W where itSs 
broken by the Eio Huallaga, in the Pongo, above the con- 
fluence of Chipm-ana. and then it loses itself in latitude Gi° 
on the north-west ot Lamas. A transversal ridge seems 'to 
connect it with the central chain, south of ParLo de Pil- 
coguanuna (or Piscuaguna), west of Cliachapoyas The 
stretches from the knot of 
Pasco and Eftianuco, towards N.If.W., between Xicaii and 
Chicoplaya, Huacurachuco and the sources of the Eio Mon- 
Tmba " CaxamarquiUa and Moyo- 
bamba. It widens greatly in the parallel of Chachapoins 
and forms a mountaiiioua territory, traversed bv deep and 
extremely hot rallies. On the north of the Paraiiio de 
Piscoguanuna (hit 6“), the central chain tlirows two brand, 2
