For any method of road-making or of paving whichmay be adopted, a steam roller of about ten to twelve lO ROLI.INCr THK KARTII K( )AI)l,i;i). tons weight is requisite in order to compact the eartliroadbed so that it will sustain the wheels which willpass over it. As well try to make the bricks of oldEgypt without straw as to try to make the roads ofto-day without a heavy steam roller. Every fullyequipped road-builder has one or more. There are fewcities which have not made some effective efforts tohave good roads, and those which have done so knowfrom experience that no good results can be expecteduntil the proper tools are used. For any system ofpavements or of roads, a steam roller is the thing firstneeded, and no contractors bid should be consideredunless he agrees to provide and use a steam roller ofat least ten tons weight so proportioned as to give notless than 500 pounds pressure per lineal inch of face ofthe roller-wheels.
