on all sides concerted efforts to elm

savings to industry and business since
the depression Of 1921. In a less no
ticeable degree, but perhaps. no less
important, the elimination Of waste IL

likewise resulted III striking savings
The wealth thus conserved in both in
dustry and the home constitutes new

wealth has been one Of the many Inn

In earlier articles attention has been
focused upon data relating to economic
phenomena as affording one means
toward eliminating waste in business
