Commissioners Beckwith and Goulet
went to Dallas today to confer with the
Polk county court relative to the pro-
posed steel bridge here. In an opinion
given out by Attorney General Craw-
ford yesterday il was held that the two
counties could adhere to their original
agreement and that Marion county
could lawfully pay for two thirds of the
bridge and Polk county for one-third
According to the Interpretation placed
upon the. law passed by the 1911 legis.
lature it was held in certain quarters
that each county could only provide
for one half of the expense of the
bridge but Attorney General Crawford
holds that by Chapter 234 Of the 1913
laws the county court is authorized to
hold meeting and after which it can
make provisions in the budget for any
part Of the cost Of the bridge agreed
upon by the two contracting counties.
