PERSIAN PEASANTS WHOSE BURDENS ARE BALES OF CAMEL'S THORN 



The black wool caps worn by these men are strikingly similar to the balloon-shaped head-coverings worn 

 in ancient Sassanian days. Camel's thorn is one of the most useful plants to be found in arid regions. It 

 provides excellent forage for camels, is much used for fuel in central and southwest Asia and, being legumi- 

 nous, it enriches the soil.
