GENERAL NOTES. 
GEOGRAPHY AND TRAVEL. 
The State of Michoacan.— Michoacan is one of the 
richest and most fertile of the states of Mexico, rich in woods, 
in mines, and in capacity of cultivation. Along with part of 
Guanajuato, it formed the ancient kingdom of Mechocean. 
Its extent is 55,693 sq. kilometres, its population about 800,000. 
The entire state is mountainous, and a considerable portion is 
occupied by lakes, among the principal of w^hich is that of 
Patgcucero. The coast line is 163 kilometres long and con- 
tains the ports of SanTelmo, Bucerico and Marauta. Among 
the principal peaks of the state are Tarcitaro (3,860 m.), 
Patambon (3,750 m.), Quinceo (3,324), Tarimangacho (3,104), 
Zirate(3,34o), and San Andres (3,282). 
Bolivia.— According to an interesting article in the last 
issue of the Spanish Geographical Society, the area of Upper 
Peru, now known as Bolivia, is 2,115,329 kilometres, or rather 
more than four times that of Spain. Its population, according 
to a census taken in some departments, and calculations made 
in others, is only 1,182,270, a figure considerably below pre- 
vious calculations. The engineer Minchi gives the altitude of 
La Paz as 3,641 m., that of Lake Titicaca at 3,824 m., and
