1916 - The Founding of Spanish California, Charles Edward Chapman

The first seven chapters of this book discuss the advance of the Spanish conquest overland toward the Colorado and Gila rivers, from 1521 to 1773, with some reference also to the occupation of the two Californias before the mainland conquest had reached those rivers. This portion of the book was presented as a doctoral thesis in May, 1915, at the University of California, in substantially the same form as it appeared here, under the title Preliminaries of the Spanish advance from Sonora to California, 1687-1773. Then follows the principal part of the work, to which were added two concluding chapters, showing that Spain did not, after 1776, continue her extraordinary efforts to develop Alta California.https://digitalcommons.csumb.edu/hornbeck_usa_3_d/1088/thumbnail.jp
