18 REPORT OF ARCHITECT OP UNITED STATES CAPITOL. 



breadth, almost approaching grandeur, of the prospect up and down and across the 

 valley of the Potomac, and to the design that when the present young plantations 

 are full-grown this great advautage of the Capitol shall not be lost. The introduction 

 of the proposed architectural terrace will indeed admit no trees to stand so near, or 

 on ground so elevated, that they will even obstruct the present distant view from the 

 main or even the ground floor. The plantations in this direction, however, will in 

 time obscure the nearer part of the city and form a continuous strong, consistent fore- 

 ground to the further sylvan slopes. 



From the terrace these plantations will in some degree limit the views to the north- 

 ward and southward, but through the removal of the old central avenue and the 

 broad gap left between the trees on the west an outlook is obtained between the 

 northern and the southern divisions of the city in which a slope of unbroken turf, 

 seen over a strongly-defined and darkly-shadowed architectural base, will be the fore- 

 ground ; a wooded plain, extending a mile beyond the foot of the slope the middle dis- 

 tance, and the partly-overgrown, partly-cultivated hills beyond the depression of the 

 Potomac, the background ; the latter so far removed that in summer conditions of 

 light and atmosphere it is often blue, misty, and etherial. Because, perhaps, of the 

 influence of the cool waters of the river passing between the dry hills from north to 

 south across this field of vision, sunset effects are often to be enjoyed from the w r est 

 iace of the Capitol of a rare loveliness.
