Portuguese missions of the lower Putumayo come into coil- 

 tact. From this point the frontier of Columbia goes toward 

 the south, crossing the Amazon near the mouth of the Ja- 

 vary, between Loreto and Tabatinga, and stretching along 

 the eastern bank of the Rio Javari, as far as 2° distant from 

 it's confluence with the Amazon ; to the W., crossing the 

 Ucayale and the Rio Guallaga, the latter between the villages 

 of Yurimaguas and Lamas (in the province of Maynas, 

 1° 25 1 south of the confluence of the Guallaga with the 

 Amazon) ; to the W. M. W., crossing the Rio Utcubamba, 

 near Bagua Chica, opposite Tomependa. From Bagua the 

 frontier stretches S. S. W., toward a point of the Amazon 

 (lat. 6° 3') situate between the villages of Choros and Cumba, 

 between Collac and Cuxillo, a little below the mouth of the 

 Rio Yaucan ; it then turns westward, crossing the Rio de 

 Chota, toward the Cordillera of the Andes, near Querocotillo, 

 and to the N. N. W., stretching along and passing over the 

 cordillera between Landaguate and Pucara, Guancabamba 

 and Tabaconas, Ayavaca and Gcmzanama (lat. 4° 13', long. 

 01° 53'), to reach the mouth of the Rio Tumbez (lat. 3° 23', 

 long. 82° 470. The coast of the Pacific Ocean bounds the 

 territory of Columbia for 11° of latitude, as far as the west- 

 ern extremity of the province of Veragua, or Cape Burica 

 (N. lat. 8° 5', long. 83o 18' ; from this cape the frontier runs 

 toward the north (across the enlarged isthmus which forms 

 the continent between Costa Rica and Veragua), and rejoins 

 the Punta Careta on the coast of the Caribbean Sea, west of 

 the lake of Chiriqui, whence we departed to make the tour of 

 this immense territory of the republic of Columbia. 



These indications may serve to rectify the maps, even the 

 most modern of which, published under the auspices of 

 Mr. Zea, and said to be constructed from the materials I 

 had collected *, traces vaguely the state of a long and

 London, 1823.
