ripe, the leaves are pounded in a mortar and reduced 
to a pulp; the mass is then placed in a conical mould

when it presents the shape of a loaf of sugar, and is 
perfectly hard. The tobacco of the Ellyria tribe is 
shaped into cheeses, and frequently adulterated with

Obbo pipes and tobacco.

Latookas are long and narrow; and the Obbo smaller 
and the neatest. All their pottery is badly burned,

elevation of the country, 3,674 feet above the sea, the
