idnight suppers. They must keep themselves fit for the
next day's work. They have the approval and loyalty of their wives
because they deserve it. In other words, the men who do the world's
work are not drunkards. They are not gluttons. They are not libertines.
They are efficient because they have healthy bodies and clean minds. It
is this efficiency which the critic from Argentina saw when he said, "I
do not look upon the people of the United States as a nation, but as a
new civilization."

=First Principles of Soil Fertility=

By ALFRED VIVIAN. There is no subject of more vital importance to the
farmer than that of the best method of maintaining the fertility of the
soil. The very evident decrease in the fertility of those soils which
have been under cultivation for a number of years, combined with the
increased competition and the advanced price of labor, have convinced
the intelligent farmer that the agriculture of the future must be based
upon more rational practices than those which have been followed in the
past. We have felt for some time that there was a place for a brief,
and at the same time comprehensive, treatise on this important subject
of Soil Fertility. Professor Vivian's experience as a teacher in the
short winter courses has admirably fitted him to present this matter in
a popular style. In this little book he has given the gist of the
subject in plain language, practically devoid of technical and
scientific terms. It is pre-eminently a "First Book," and will be found
especially valuable to those who desire an introduction to the subject,
and who intend to do subsequent reading. Illustrated. 5x7 inches. 26
