The Arab population also had rapidly increased in numbers, thanks to the very high birth- rate, the cessation of the Turkish conscription which had taken many young men never to return, the lowering of the high deathrate for which the Public Health Department of the Government may claim at least some credit, and to some illegal immigration from neighbouring Arab countries. Beneath the superficial order and progress, however, ea conflict had been created between two national ideals, and under the system imposed by the Mandate it could only be solved if one or both of these ideals were aban- doned'.1 The lands east of the Jordan, which had been little more than nominally administered by the Ottoman government, were ad- ministered from 1918 by Faisal's Arab government at Damascus. However, at the San Remo Conference of April 1920 this region was assigned to Britain as part of the mandate for Palestine, with the proviso^ however, that *in the territories between the Jordan and the eastern boundary of Palestine as ultimately determined, the mandatory shall be entitled, with the consent of the Council of the League of Nations, to postpone or withhold application of such provisions of this mandate as he may consider inapplicable to the existing local conditions, and to make such provision for the ad- ministration of the territories as he may consider suitable to those conditions*.2 Soon after the collapse of the Damascus Arab government before the French in July 1920, therefore, the High Commissioner for Palestine convened the local Arab notables at as-Salt, then the principal town of the region, and informed them 1 Royal Commission Report (1937), 61. 2 Mandate, Art. 25,
