The gain in New York State is due largely to the fact that 

 the state has bonded itself for $50,000,000, and that $5,000,000 

 a year is being expended by the state, in addition to an equal 

 sum by the counties, in building state highways. 



The gain in Georgia is largely attributed to the use of 4,500 

 prisoners on the public roads of the state. 



The gain in South Carolina, Alabama and Florida is due 

 largely to the fact that sand-clay roads are being built and that 

 this is a very cheap and satisfactory type of road building.
