 very wrongly, that it was placed there with the

 The other result was equally unexpecti

The walk by which the mansion is approached 

 runs parallel and close to the northern fence, sepa- 

 rated from it only by Brown's belt. Now this 

 belt, while young, answered

 Granted that a belt has thus outgrown its original 

 design as a screen from a public road — what really 

 is the remedy ? We ourselves do not doubt very 

 seriously or in a very melancholy spirit. As to the 

 opposite belt, Repton made very short and good 

 work of it. He thinned it just so much, and with 

 such good taste, that whether the spectator were 

 stationary or moving, the pagoda at Kew, and the 

 best points of the intermediate scenery, should be 

 visible just when and where they ought — and with 

 the best possible effect. 



The drive by which the mansion is approached 

 is admirably planned. It turns to the left from 



the lodge — and in a very few yards ph 



spectator beyond the power of observe _ 

 which mars the beauty of the walk. All that 1 

 sees is the boundary belt on the north. The drb 

 winds on in graceful course — with the house i 

 front — and the varying Surrey view on the lcft- 

 the lake is crossed— and then by a fresh winding 

 drive he arrives at the door. Within a space so 

 limited, a better drive could not well have been 

 arranged, although we confess that to our humble 

 apprehension it is susceptible of very considerable 

 improvement. Upon such improvement it would

qualities enabling us to use it, not merely as being ne- 

 cessary for the health of plants, but also as the best and 

 only means of affording an efficient and natural tempe-

 researches of many eminent philosophers that the ob-
