In this volume is brought together practically all that is known concerning the voyages made by the Spaniards along the California and Oregon coast line between 1539 and 1602. The series opens with an account of the epochal voyage of Ulloa in 1539, and this is perhaps the most interesting record in the entire volume. The compiler has been able to reproduce Ulloa's original journal, has furnished an adequate translation, and has thus brought into full relief what has hitherto been one of the most elusive and tantalizing episodes of early exploration. The body of the volume closes with an account of the project to found a settlement at Monterey, as a result of the report and recommendation of Vizcaino. The notes, appendixes, and other explanatory matter with which the volume terminates are so copious and so necessary for the adequate interpretation of the text that one questions whether it would not have made the work more useful and convenient for the student, to have bound them in a separate volume or placed them in a portfolio. The collection and interpretation of these interesting records represents the highest type of historical research work, and the volume can be most cordially recommended to the student or general reader.
