WASHINGTON, March 25 (AP)The success of Secretary Hull's proposal for evacuating political refugees from Germany and Austria, informed persons agreed today, will depend largely on what restrictions are laid down by the Nazi government. Germany, they said, has followed the practice of permitting emigrants to take little or no money with them. This policy has the effect of discouraging the refugees, and alSO raises the question in other countries of whether to welcome penniless persons. Hull sent telegrams to nine European and 20 American nations yesterday, proposing the setting up of an international committee to favilitate the emigration through financing by private organizations. State department officials did not anticipate that Germany would offer much objection to emigration in itself, since most of the refugees would be Jews and therefore unwanted to Nazi states. Germany's quota under the immigration act of 1924 has been less than half-filled in recent years, due partly to Nazi restrictions on emigration and partly to more stringent. American supervision. Officials calculated that, if the unwilled portions of the quotas of Germany and Austria 'were combined, about 15,000 persons could be brought into the United States bteween now and June 30. First evidence of support for Hull's evacuation proposal came from London, where it was received sympathetically in informal discussions . The world federation of Polish Jews appealed to Poland to extend protection to 30,000 Jews of Polish extraction in Austria. The United Palestine appeal began a United States campaign for $4,- 500,000. Since the Nazi regime in Germany, officials said, organization has settled 85,000 Jews in Palestine.
