of communication between Upper Assam and Upper 
At about 25^-20' the Chindwin River receives the Tuzu, a 
considerable tributary, but the exact point of junction has 
not yet been observed. The Tuzu flows from the northeast, 
and its destination seemed problematical, since its valley 
appeared to be shut in on both sides by lofty peaks through 
which no exit was possible. Col. Woodthorpe, however, dis- 
covered that the river, after joining another stream coming 
from the southwest, turns off at right angles, and makes its 
wav through a magnificent gorge between Saramcthi and 
another mountain 11,000 ft. high. The teak forests of the 
Chindwin River are very valuable, and are exploited by an 
Angle-Indian Company. King Thebaw's repudiation of his 
agreement with this company was one of the causes of the 
war that led to the annexation of Burma. 
South of Manipur and West of Burma, lies a mass of lofty 
hills, inhabited by several closely allied tribes, among whom 
are the Chins. 
America. — The Limits of Venezula and Brazil.— 
Count E. Stradelli has furnished the Bolletino della Societa 
Geographica Italiana (Aug. and Sept., 1888, Jan'y, 1889) with 
an interesting account of his journeys in Brazil. The January 
issue contains the trip from Cucahy to Manaos. In the 
course of this article the dividing line between Brazil and 
Venezuela is given. This line commences at the principal 
source of the Memagui, an affluent of the Haguieni, which 
latter is a tributary of the Rio Negro. The point is 2^-1'- 
29.3' N. latitude and 70°-34'-57.65" 'W. longitude. Disputed 
territory extends farther west, but here the Colombian, Re- 
public and Ecuador have claims. The boundary follows the 
watershed to 70^-2o'-44.i i" W. longitude, thence goes to the 
sources of the Macacuny in i^-i2'-3 ' N. latitude, and 69°- 
22-35" W. longitude, descends the Rio Negro to 78''-34'- 
18.50' W. longitude thence goes straight to the Serro Cupy, 
and follows the water-parting by the Mountains Imeri, 
Tapyra Peco, and Curupira. Hence it inclines to the north, 
following the Parima range which divides the basin of the Rio 
Branco from that of the Orinoco. At the Serro Maschiati, 
4''-3i' N. latitude and 47''-9'-35" W. longitude, it re-assumes 
the east and west direction along the Pacaraima range. It 
passes by Mont. Piauassu in 3°-32'-24" N. latitude, between 
the rivers Uraricapara and Auapira, and Mount Rorainia, and 
thence to the confines of British Guiana. Most of this boun- 
dary runs through an inhospitable and unexplored country.
