for good, Edison went back the laboratory and looked for
ways recouping his loses.
Had the mill Ogden been success, Edison's reputation
as inventor would have been superceded his fame an

undertaking Dunderland ended failure.

achieved what Edison had only dreamed about— the radical
reduction the cost producing basic industrial good. Edison soon went into
the cement business for himself, using equipment designed in
his laboratory and experience gained materials handling at
Ogden. His efforts make the most the failure ore
milling illustrates the broad scope his commercial outlook
and the laboratory's strong engineering skills. His laboratory had developed

exploit. The lab carried out experiments reheating
