Brick Roads. It is said that the best road mate- 

 rial to resist the wear of automobiles is brick. Brick 

 pavements cost considerably more than the macad- 

 amized road, but they are more satisfactory in many 

 ways. They last longer, they require less repair, 

 and they are not so dusty. In many places, as in 

 Cleveland, Ohio, the brick pavements are being ex- 

 tended from the ,city limits to the county line, where 

 the adjoining county is planning to take it up and 

 extend the road to other cities. (Figs. 101, 102, 106.) 



The Draft on Different Surfaces. How much a 

 team can pull depends upon the firmness and 

 smoothness of the roadbed and the grade. A load 

 that three horses can just pull on level, hard asphalt, 

 would require seven horses on smooth block pave- 

 ment, fourteen horses on cobblestone, forty horses 

 on an ordinary country earth road, and eighty on 

 a sandy road. This shows the need of hard roads.
