about twelve inches apart, and filling tin* spaces between them with 

 concrete: upon tliis foundation the heavy stones of the abutments 

 w<tc laid. The superstructure of this archway is to be of Ohio stone, 

 and of brick. 



About the same progress has been made with the Nethemead arches. 

 The material upon which the piers rest is a sharp, clean sand. Con- 

 crete one foot in depth was laid, upon which the walls were built ; 

 when these had been carried up about three feet, a heavy storm filled 

 the pit in which the foundations were, with water to a depth of eleven 

 feet. There being no outlet, the water filtered away between and 

 around the piers and abutments in a few hours, but the stability of the 

 masonry was not in the least disturbed thereby. 



The waterway under this bridge is paved with flagging covered 

 with one foot of concrete, to protect the foundations from any 

 possibility of being undermined in times of excessive storms, or of ac- 

 cidents to the pools, which will be located above it. The superstruc- 

 ture is to be of granite, and Ohio stone facings, with a brick arch. 



RETAINING WALLS. 



The retaining walls at the south end of Breeze Hill, which sustain 

 the walks passing between the abutments of the bridge and the lake, 

 have been built. They are of uncoursed Rubble masonry. The width 

 of waterway between these walls is forty feet, and the water alongside 

 the walls is to be one foot in depth, when the water in the lake is at 

 winter level, and four when at summer level. The top of the wall is 

 to be three feet above the summer level of the lake. 



LULLWOOD BRIDGE. 



This bridge carries the main walk over the Lullwater, and is to have 

 a clear span of about thirty feet, with two side spans of thirteen feet 

 each. The height from the surface of the water at summer level to 

 the under side of the bridge will be seven feet, to permit the free pas- 

 sage of boats in summer, and skaters in winter. The foundations for 

 the piers and abutments have been laid, and the walls completed with 

 the exception of the capstones. 



DAIRY HOUSE. 



A stone dairy house has been commenced, and the Avails carried up
