the problem, since Palestine, besides being the Holy Land for
Christians, contains many places sacred to the Jews, and others

tions, and co-operative agriculture in which both peoples can
take part, may in time relieve the tension. For the present,' the
British administration has curtailed the immigration of Jews,
and is preoccupied with the task of maintaining its own authority
in face of Arab risings. A plan has recently been proposed to
divide Palestine into a Jewish State, an Arab State, and an area
including Jerusalem, to be kept under British control.
Tanganyika and som^ smaller parts of Africa are British
Class B Mandates. Such territories are governed as Colonies,
but the Mandatory Power must prohibit abuses such as traffic

Mandate—Nauru in the Pacific—and this is administered for
Britain by the Commonwealth of Australia.
The Kingdom of Irak was a British Class A Mandate until

Occupation, is now like Irak, independent but linked to Britain
by treaty. The Suez Canal, though in Egyptian territory, is in
part the property of the British Government, and its use is
regulated by international agreement. There is no doubt that if
