Here is a fascinating letter British Chief Rabbi Nathan Marcus Adler sent to Hamaggid (January 10, 1889). He urges his rabbinic colleagues in Russia, Poland and Lithuania to help stem the tide of Jewish emigration to Great Britain, which had begun in waves after 1881 when a great wave of pogroms had begun to take place. Rabbi Adler points out that the British Jewish community has done it all it could for the refugees. The rabbis should know that there is no livelihood for them in Britain. Most work on the Sabbath and holidays, and some have even converted to Christianity. It is simply not possible for the Jewish community to do more. London is not a golden city. Therefore he requests all these rabbis publicize these things, so the people will know that immigration to Britain is not an ascent, it's a descent..
The same letter was also sent to Yehuda Leib Gordon's Hameliz, where for some strange reason R. Adler labored under the impression that the rabbinic audience he addressed was reading. It appeared in the January 11, 1889 issue:
