The oil-deposits of Persia are so rich that it will soon be necessary to increase tenfold the projected development of the equipment, pipe-lines, and refineries, to deal with future production. Even in our time the natives collect the oil by rudimentary processes and transport it on the backs of camels to the markets of the interior, where it serves as an object of exchange. Persia is one of the few countries in which numerous spontaneous springs and seepages reveal the existence of oil. In certain valleys it flows along the slopes and pours into the rivers, making the water unfit for consumption. The _Anglo-Persian_ already ranks among the chief oil-producing companies of the world. It is precisely this success, we may believe, which has caused so much apprehension in the United States on the subject of the rivalry between British and American producing companies. The _Anglo-Persian_ controls an almost unlimited production in Persia, and as soon as there are enough pipe-lines and reservoirs, the output will increase in enormous proportions. _From 1923 onward, the_ Anglo-Persian, _by itself, will be in a position to supply a large proportion of the needs of Great Britain_. It will then be free of the contract which, for more than seven years, has bound it to the _Royal Dutch-Shell_, obliging it to dispose of a considerable portion of its production through the latter company. When its program is completed, the _Anglo-Persian_ will possess a fleet, the capacity of which will exceed a million tons. Expenses are small, because of the great productivity of the wells, which gives to Persia a marked superiority over all the other oil-fields of the world, except perhaps Mexico. Its yield of benzine and kerosene is much superior to that of most of the oil-fields of the United States; it is richer than that of Mexico.
