 THE WATER FRONT AT MUKAIXA, ON THE INDIAN OCEAN, COAST OF ARABIA 



Myrrh comes from a tree developed in the form of an undergrowth in the Red Sea 

 coast, where vegetation is scant, water scarce, and temperature high. Myrrh is formed like 

 cherry-tree gum, or from artificial incisions through the thin bark. It is at first a juice, then 

 oily, soft, yellowish, golden, finally hard and reddish. It is collected mostly by the Somali, 

 both at home and across the Aden Gulf, in Arabia, and formerly entered commerce by way 

 of Egypt. It is now, in normal times, carried to the great fair of Berbera, there purchased 

 by the Banians of India, and shipped by way of Asia to Bombay, where it is assorted into 

 grades and put into chests and sent to the markets of the world.
