REPORT 



ENGINEER IN CHARGE. 



Engineer's Office, Prospect Park, 

 January 1st, 1867. 

 Messrs. Olmsted, Vaux & Co., 



Landscape Architects and Superintendents. 



Gentlemen, — The accompanying reports of Mr. Bogart and Mr. 

 Culyer, together with the annexed maps, give full information rela- 

 tive to the progress that has been made in the surveys and construc- 

 tion of the park, the condition of the materials and tools on hand, 

 and the organization and discipline of the labor force. 



It will be seen, by reference to the progress map, that the topo- 

 graphical survey of the original surface is not yet complete. This 

 work will be pushed forward as vigorously as the other duties of 

 the assistants, connected more immediately with actual construction, 

 will permit, and it is hoped that the necessary data will be collected 

 and recorded upon the map before the opening of work in the 

 spring. 



The labor force has been chiefly employed in grading and in col- 

 lecting materials, such as soil, peat and stone, for future use. 



The price of excavation has varied from 12 cents to 11 20 per 

 cubic yard, depending upon its character, its final distribution, and 

 the length of haul. 



The force employed exclusively upon earth excavation has cost 

 $106,600, of which 43 per cent, has been paid to cart gangs, and 57 

 per cent, to barrow gangs. 



The average cost of excavating, moving, and disposing of material 

 of all kinds, since the commencement of work in June up to the 

 present date, has been nearly five cents less than the average up to 

 the 1st of September.
