1930. From Nile to Niger with the Jews. This volume is the consequence of eleven years of intensive research, after the preliminary five years spent in Jamaica. It naturally follows along the line of study, with chapters parallel to the steps of investigation, except that the Hebrewisms are, for the most part, grouped together at the beginning of the work. The argument at best must be a cumulative one, and as a single witness may be accused of bias or of being liable for error, quotations must necessarily be multiplied, even with a danger of becoming tedious. The two closing chapters will deal with a general summary and the author's personal deductions.
