From Klipkaps posting it maybe thought that Palestinians were flocking to Cis Jordan as the Jewish farms were extremely potent, and awash with modern technology. So how come during the period of 1922 to 1930 there was an exodus of Palestinians?

The fellah as a cultivator.The fellah is neither lazy nor unintelligent. He is a competent and capable agriculturist, and there is little doubt that were he to be given the chance of learning better methods, and the capital, which is a necessary preliminary to their employment, he would rapidly improve his position. Meanwhile, however, the income which he can procure from his inadequate farm is insufficient to maintain him in a decent standard of comfort and leaves no margin whatever for improvements.

Expenditure by KerenKayemeth and KerenHayesod.The amounts spent by these two agencies have been formidable, and it is quite impossible that they will ever be repaid in full. In the former case no question of repayment arises, as the land is not to be sold to the settlers. Yet it is certain that no adequate interest in the form of rent could be paid by the settlers on the outlay of the Fund on their holdings. In the case of the KerenHayesod also the outlay has been lavish, and the whole of the colonies are so overcapitalised that it will prove essential both to write off a considerable amount of the outlay and to fix the rate of interest on the balance at an uneconomic level if the outlay is to be liquidated. The Jewish National Fund and the KerenHayesod have very kindly submitted consolidated statements of their expenditure, which are printed as Appendices 8 and 9 to this Report. In the former, excluding the items " Urban Land ", " Urban Buildings ", and " Lands ", the sum of £1,545,659 appears to have been spent on agricultural colonisation. In the latter, the items " Urban Colonisation ", " National Organisations ", " Investments ", and " Jewish National Fund " do not appear to be expenditure on colonisation in the country. The balance is £3,345,531. Adding these two sums together, the total cost of agricultural colonisation by the Zionist Organisation appears to have been £4,891,190.* The number of persons actually settled for this sum is shown in Appendix 10a statement submitted by the Jewish agency.
Population of settlements.The total population of the Zionist settlements in 1930 (included therein being the " supported settlements ") consisted of 4,406 adults, and 2,364 children under 15 years of age. The cost of colonisation of a family has thus been very large.

" Article 11.The settler undertakes to work the said holding personally, or with the aid of his family, and not to hire any outside labour except Jewish labourers."

Zionist policy in regard to Arabs in their colonies.The above quoted provisions sufficiently illustrate the Zionist policy with regard to the Arabs in their colonies. Attempts are constantly being made to establish the advantage which Jewish settlement has brought to the Arab. The most lofty sentiments are ventilated at public meetings and in Zionist propaganda. At the time of the Zionist Congress in 1921 a resolution was passed which '' solemnly declared the desire of the Jewish people to live with the Arab people in relations of friendship and mutual respect, and, together with the Arab people, to develop the homeland common to both into a prosperous community which would ensure the growth of the peoples." This resolution is frequently quoted in proof of the excellent sentiments which Zionism cherishes towards the people of Palestine. The provisions quoted above, which are included in legal documents binding on every settler in a Zionist colony, are not compatible with the sentiments publicly expressed.

The same remark applies to the following extract from the Memorandum submitted by the General Federation of Jewish Labour to the " Palestine Commission of Enquiry " (i.e., the Commission on the Palestine disturbances of August, 1929) :

" The Jewish Labour Movement considers the Arab population as an integral element in this country. It is not to be thought of that Jewish settlers should displace this population, nor establish themselves at its expense. This would not only be impossible both from the political and economic standpoint, but it would run counter to the moral conception lying at the root of the Zionist movement. Jewish immigrants who come to this country to live by their own labour regard the Arab working man as their compatriot and fellow worker, whose needs are their needs and whose future is their future."

The effect of the Zionist colonisation policy on the Arab. Actually the result of the purchase of land in Palestine by the Jewish National Fund has been that land has been extraterritorialised. It ceases to be land from which the Arab can gain any advantage either now or at any time in the future. Not only can he never hope to lease or to cultivate it, but, by the stringent provisions of the lease of the Jewish National Fund, he is deprived for ever from employment on that land. Nor can anyone help him by purchasing the land and restoring it to common use. The land is in mortmain and inalienable. It is for this reason that Arabs discount the professions of friendship and good will on the part of the Zionists in view of the policy which the Zionist Organisation deliberately adopted.

As can be seen from the above report there were no extra jobs in the area from Zionist colonisation. And the Land was not farmed by the Arabs which reinforces the palestinian Arab exodus from the area, there was no immigration of Arabs at all. A field mouse plague was caused by Zionist farming causing problems for the Arabs in the area.

The colonists have not yet begun to repay any of the money due to the KerenHayesod for installation, nor is rent being paid to the KerenKayemeth.

The colonists were getting supported from outside sources not from their own endevours.
