death, in his seventieth
year, in April, 1910. Several articles bearing on the mores, and
realizing in part the programme outlined in the last paragraph of the
foregoing Preface, have been published: "The Family and Social Change,"
in the _American Journal of Sociology_ for March, 1909 (14: 577-591);
"Witchcraft," in the _Forum_ for May, 1909 (41: 410-423); "The Status of
Women in Chaldea, Egypt, India, Judea, and Greece to the time of
Christ," in the _Forum_ for August, 1909 (42: 113-136); "Mores of the
Present and the Future," in the _Yale Review_ for November, 1909 (18:
233-245); and "Religion and the Mores," in the _American Journal of
Sociology_ for March, 1910 (15: 577-591). Of these the first and last
were presidential addresses before the American Sociological Society.
All are included in Volume I (War and Other Essays) of a four-volume set
of Sumner's writings, published since his death by the Yale University
Press.

Regarding the treatise on the "science of society" (for he had decided
to call it that instead of "sociology") mentioned in the Preface, it
should be said that Professor Sumner left a considerable amount of
manuscript in the rather rough form of a first draft, together with a
great mass of classified materials. He wrote very little on this
treatise after the completion of _Folkways_, and not infrequently spoke
of the latter to the present writer as "my last book." It is intended,
however, that the _Science of Society_ shall be, at some time in the
future, completed, and in such form as shall give to the world the
fruits of Professor Sumner's intellectual power, clarity of vision, and
truly herculean industry.

The present revision of _Folkways_ incorporates but few and unimportant
corrections. Certain of these are from the hand of the author, and
others from that of the present writer.

A photograph of Professor Sumner has been chosen for insertion in the
present edition. It was taken April 18, 1902, and is regarded by many as
being the most faithful representation in existence of Sumner's
expression and pose, as he appeared in later years. This is the Sumner
of the "mores," with mental powers at ripe maturity and bodily vigor as
yet unimpaired by age. The Yale commencement orator of 1909 said of
Sumner, in presenting him for the Doctorate of Laws: "His intellect has
broadened, his heart has mellowed, as he has descended into the vale of
years." While advancing age weakened in no respect the she
