Dedicated to my beloved brother, R. Y. Block, and his faithful wife, Mrs. Clara Blalock of 2742 Sinclair Avenue, Concord, California.   Though he now is an invalid confined to his room, under the tender care of his wife.    Yet for over 50 years he has been one of the most faithful missionaries of the great Northwest, California, and Oregon, where he labored untiringly and successfully as a true Baptist home and faith missionary.
