the driveway and paths across the valley of the Bronx River was com- 

 menced in 1904 and completed in 1905. The granite bridge carrying the 

 driveway and paths across the valley of the lakes was constructed 

 during 1905. The approach to the bridge at the Woodlawn Road en- 

 trance was built in 1905 and 1906. The boulder bridge, which replaced 

 the old wooden "Blue Bridge" over the Bronx River at the northern end 

 of the Hemlock Grove, was commenced in the autumn of 1906, and com- 

 pleted in September, 1907, built entirely of rounded glacial drift boulders 

 taken mainly from old stone walls within the grounds. 



The concrete-steel bridge which spans the gorge of the Bronx below 

 the water-fall was constructed by the Department of Parks in 1910, 

 from designs prepared by Mr. Samuel Parsons, then Landscape Archi- 

 tect of the Department of Parks. A wooden bridge which spanned the 

 river at a much lower level between the site of the new bridge and the 

 water-fall, which had stood for many years and had become unsafe, was 

 subsequently removed. 



The bridge carrying the Bronx and Pelham Parkway over the Bronx 

 River was constructed by the Department of Parks in 1905 and 1906, 

 and was dedicated to Linnaeus on May 23, 1907, the two hundredth 

 anniversary of his birth, with suitable ceremonies participated in by 

 several New York institutions. 



Construction of boundary fences was commenced in the spring of 

 1908, and the fence along the property line of Fordham University from 

 the Elevated Railway station to the Southern Boulevard entrance was 

 completed during that year. The fence along the western boundary 

 of the Garden, along the right of way of the New York Central & Hudson 

 River Railroad Company, was built during 1910 and 191 1 by the Rail- 

 road Company at its own expense, after an agreement had been entered 

 into between the City, the railroad company and the Garden, which 

 provided that the telegraph wires strung on poles along this line should 

 be placed in a conduit, which was also done at the expense of the rail- 

 road company. During the grading of the Bronx Boulevard along the 

 eastern side of the grounds in 1910, a retaining wall was built by the 

 Department of Public Works of the City from a point nearly opposite 

 power house no. 2 to the northeastern corner of the grounds; construc- 

 tion of the boundary fence along the Bronx Boulevard from the southern 

 end of this wall southward to the Garden nurseries was commenced during 

 the summer of 1912 and completed during 1913.
