etc., are used, have been laid in the park. Their character and 

 quality varies according to the judgment and experience used in the 

 manipulation of the ingredients by the contractors, and the manner 

 and thoroughness of laying them. Pavements have been laid by 

 the Fiske, Scrimshaw, Scharf, Evans, Long Island, and other pro- 

 cesses. The first of these did not do well "on .the park, disintegra- 

 tion of the surface rapidly ensuing, in eonsecpuence, it is believed, 

 from the use of pine tar as the concreting material. Some of the 

 walks laid by the Fiske process were in bad condition for use, and 

 were re-surfaced during the year with Scrimshaw. 



The Scrimshaw has been most extensively used on the park ; it 

 seems to have been more carefully manufactured and laid than any 

 other, and, as a consequence, has given better results. 



WATER SURFACES. 



The Ambergill has been entirely completed, and the slopes of 

 the two large pools formed. 



A small pool has been made at the north-easterly end of the hill, 

 near the cemetery, at the point where it was formerly intersected 

 by Ninth street. This pool has been entirely completed, and, in 

 connection with it, a tail ten feet high has been built, over which 

 water is conducted for the supply of the lower pools and the Am- 

 bergill. In the small basin at the foot of these falls, two hundred 

 brook trout, purchased in the summer, were placed. A constant 

 supply of running water has preserved and kept them in a healthy 

 condition. They are growing rapidly, and can be observed by 

 visitors as they pass over the rustic bridge that crosses the outlet of 

 this pool. 



The system of pools, falls, and watercourses has been in use 

 during the larger part of the season, and a circulation maintained 

 through the whole line of the watercourse from the pools, and over 

 the falls to the main lake. 



The large fountain at the Plaza, which is supplied with water 

 from the city distribution, has been in use from two to seven in the 

 afternoon during the fine weather of the spring, summer, and fall 

 season. 



In the early part of the year the work of excavating and puddling 

 the lake was pressed to completion, and water was let into the 

 newly-finished portion (nearly thirty acres in area) on the 20th of 

 Auarust.
