TWENTY-FIRST ANNUAL REPORT 107 



herewith. Even though the blast was covered by large logs 

 chained together, and these in turn covered with a mat made of 

 large ropes, water and stones were thrown to a height far above 

 the elevated railroad structure. 



The soft mud was then removed, in some places, to a depth 

 of six feet, to the clay bottom, to provide suitable foundations 

 for the sea-wall. The sea-wall was built of large stones without 

 mortar to within one foot of the water-level, and the remainder 

 was built of rubble masonry. The wall, in plan, is a compound 

 reversed curve, to conform to the old water line at the edge of 

 the dock. 



A slip was built within the wharf area to admit the launches, 

 whereby they may discharge passengers on one side and receive 

 them on the other, and thus greatly expedite the handling of 

 the launch traffic. 



Drains from the Boat House were laid, the fill leveled off, 

 and a floor of six inches of concrete was laid over the entire 

 wharf area. A platform was constructed two steps above this 

 level along the rear edge, and concrete benches placed there for 

 the accommodation of the public. 



A row of electric-light posts was erected, each post having 

 a cross arm carrying a large light at each end, and a socket in 

 the center for a flagstaff. 



An enclosure was made at one side of the launch shp and 

 provided with a canopy and concrete benches for the reception 

 of a sufficient number of persons to load a launch. This serves 

 to prevent confusion, and the struggling of crowds to get on 

 the launches during rush hours. 



Formerly the water had been too deep in some places along 

 the wharf, and in other places the river bottom was composed 

 of sticky mud. These constituted most dangerous conditions for 

 persons entering and leaving the rowboats. Accordingly, the 

 mud was removed and fill put in, making shallow water and a 

 solid bottom for a distance of forty feet from the wharf. 



We now have a most attractive and satisfactory boating 

 pavilion which will be good for all time, and require few repairs. 



Numerous surveys were made and maps drawn with refer-
