Note 20 — Chapter II · THE JEWISH COLONIES IN POLAND AND LITHUANIA
Israel Friedlaender translation
It need scarcely be pointed out that, in speaking of the Jewish immigration into Poland, we have in mind the predominating element, which came from the West. It is quite possible that there was an admixture of settlers from the Khazar kingdom, from the Crimea, and from the Orient in general, who were afterwards merged with the western element.
