THE TERRACE. 



Molesworth gives the following formulae for retaining walls 



E = Weight of Earthwork per cube yard. 



W = Weight of Wall. 



H = Height of Wall. 



T = Thickness of Wall at top. 



T = H x Tabular No.

In calculating the strength of surcharged walls, substitute Y for H, 

 Y being the perpendicular at the end of a line (L = H) measured 

 along the slope to be retained.

Y= 171 H in slopes of I to I. 

 = 1-55 H i^toi. 



1-45 H 2 to i. 



1-31 H 3 to i. 



1-24 H 4 to i. 



An etching is given of the terrace garden at Friar Park, Henley, 

 the residence of Frank Crisp, Esq. It serves to illustrate what 

 is meant by a base being made to a house. In this case walks 

 lead from the forecourt, from the garden entrance, and from the 

 conservatory, on to an upper terrace, from which walks descend 

 to a lower terrace garden with its parterre, which, in its turn, gives 

 place to the flowing lines of the pleasure gardens. In this case a 

 low moulded plinth is fixed on the top of the grass slope.
