proof buildings; that OILY the owner or
occupant can assure it. He suggests a
plan, already tested, that the assured
must assure himself by making all COM
panies mutual (as they GOV practically
are). We should have the companies
stock in capital, and be mutual in liabil-
ity to assessment. This subject is the
more important because the annual
losses are equal to the amount gained by
the gainful labor of 100000 men.
