most reliable data, the lengths of various rivers, and gives the 
following as the eight longest: (1) Missouri-Mississippi, 4194 
miles; (2) Nile, 4020; (3) Yang-tsze-kiang, 3158; (4) Ama- 
zon, 3063; (5) Yenisei-Selenga, 2950; (6) Amur, 2920; (7) 
Congo, 2883; (8) Mackenzie, 2868. The map of Hum hreys 
Abbot is the authority for the Missouri-Mississippi, which 
_ Kioders gives as 3658 miles. 
AMERICAN Notes.—Governor Fontana, of Chubut, has recently 
explored the Chubut and its tributary, the Charmate, passing 
through the Andes by a very low pass, since the confluence of 
e two mentioned rivers is only eighteen hundred feet above 
sea-level, and at sixteen hundred feet above the sea the valley 
of the Cercorado, a river flowing into the Pacific, was reached. 
On their return the party found a large lake, through which the 
river Senguel flows. The Welsh colony on the Lower Chubut 
will probably colonize on this lake. 
: jon Jose Santelices has ascended Licancaur, a volcano on the 
eastern boundary-line of the Chilian province of Antofogasta. 
_ Tambos— uses of a single room, with a low, stone bench—are 
found on the Inca road which leads to the summit. The crater 
=~ Was found to have a bottom thirteen hundred feet in diameter, 
_ with a pond four hundred feet by three hundred and fifty feet in 
its centre. On its banks there are remains of some thirty large 
stone houses built by the Indians, and a large quantity of fuel
