DOMESTIC FOWL.

duces in great abundance. It is brought in crystals of about 
12 inches long and in diameter. This is hawked about every¬ 
where in Angola, and, next to caHco, is the most common medium 
of barter. The Kisama are brave; and when the Portuguese 
army followed them into their forests, they reduced the invaders 
to extremity by tapping all the reservohs of water, which were no 
other than the enormous baobabs of the country, hollowed into 
cisterns. As the Kisama country is iU supplied with water other¬ 
wise, the Portuguese were soon obhged to retreat. Their country 
lying near to Massangano is low and marshy, but becomes more 
elevated in the distance, and beyond them he the lofty dark 
mountain-ranges of the Libollo, another powerful and independent 
people. Near Massangano I observed what seemed to be an 
effort of nature to furnish a variety of domestic fowls, more 
capable than the common kind, of bearing the heat of the sun. 
This was a hen and chickens, with all theh feathers curled 
upwards; thus gmng shade to the body without increasing 
the heat. They are here named “ kisafu ” by the native 
population, who pay a high price for them when they wish 
to offer them as a sacrifice, and by the Portuguese they are 
termed “ arripiada,” or shivering. There seems to be a tendency 
in nature to afford varieties adapted to the convenience of man. 
A kind of very short-legged fowl among the Boers was obtained, 
in consequence of observing that such were more easily caught 
for transportation, in theh frequent removals in search of pasture. 
A similar instance of securing a variety, occurred with the short- 
limbed sheep m America. 
Keturning by ascending the Lucalla into Cazengo, we had an 
opportunity of visiting several flourishing coffee plantations, and 
observed that several men, who had begun with no capital but 
honest industry, had in the course of a few years acquhed a com¬ 
fortable subsistence. One of these, Mr. Pinto, generously fmnished 
me with a good supply of his excellent coffee, and my men with a 
breed of rabbits to carry to their own country. Theh lands, 
gTanted by Government, yielded, without much labour, coffee 
sufficient for aU the necessaries of hfe. 
The fact of other avenues of w^ealth opening up so readily, seems 
like a providential invitation to forsake the slave-trade and engage
