 labor has been concentrated upon fewer points, and these have been 

 steadily pushed forward to completion. No strikes have occurred 

 among the laborers, and but one among the mechanics, and that was 

 due to an arbitrary society rule which was finally disregarded by the 

 park employees. 



ROADS. 



The park drives have been constructed principally with rubble 

 stone foundations. Heretofore the Eoa Hook gravel was placed 

 directly upon the broken stone. This season two inches of coarse 

 gravel, with a small admixture of loam was placed upon the broken 

 stone, and two inches of Roa Hook upon this. 



By the substitution of park gravel, the cost of the drives was ma- 

 terially reduced, as the material was less expensive, and it packed 

 more readily under the action of the roller. There is every reason 

 to suppose that these drives will be equally as durable as the more 

 expensive kind, because the wear of the vehicles will still come upon 

 the Roa Hook gravel, and before this two inches of surface gravel 

 is worn out the drives will require to be surfaced with fresh mate- 

 rial. Continued and careful observations have been made on the
