On many of the islets numerous tropical fruits are found growing wild, but they are no doubt escapes from cultivation, just as the large herds of wild cattle, horses, donkeys, pigs, goats and dogs - the last large and fierce - which occur abundantly on most of the islands have escaped from domestication.
Horses are bred to some extent, while the native race of donkeys is remarkably small in size.
There are very few roads; goods are transported on camels, or on horses and donkeys in the hilly tracts.
Although some of these elephants are believed not to have been larger than donkeys, the height of others may be estimated at from 4 to 5 ft., or practically the same as that of the dwarf Congo race.
Cattle, sheep, mules and donkeys are sent in large numbers to Egypt.
