Those who have _them in charge can organize side or collateral business enterprises, and so manipulate their roads as to seriously cripple their competitors and add to their own profits. These are but some of the possibilities incident to·raiI‘- roadmanagement. Nevertheless, with allrtheir capacity forinjus- _ tice, they cannot be dispensed with.
