which the most distant part of the ground is seen by the eye at 

 k. Now, the larger the angle at which this distant point of the 

 ground is seen by the spectator at k, the more distinctly will he 

 discern objects there; and,

as 



these different angles are repre- 

 sented by the sines to each (z i), 

 it follows that, in rising ground, 

 the most favourable slope for 

 seeing objects from a fixed point 

 is that represented by the line 

 a J", or some slope near to that 

 line ; say a slope forming an angle 

 between 20° and 30° with the 

 horizon. In the case of falling 

 ground, it will be observed that 

 the most favourable slope lies be- 

 tween the same angles ; though in 

 falling ground the objects are not 

 nearly so advantageously seen as 

 in rising ground. A level sur- 

 face, it will be observed, possesses 

 exactly the same advantages, in 

 point of seeing objects placed on 

 it, as a surface rising at an angle 

 of between 20° and 30°. Hence, 

 for the display of flower-beds, a 

 lawn which has a level surface, 

 or one which rises at any angle 

 under 30°, is much better adapted, than one which slopes from 

 the eye at any angle, however small. 



The decorated ground in the Lawrencian Villa is remarkable 

 for the very great variety which it contains in a very limited space ; 

 and the secret of producing this variety consists in introducing 

 numerous small groups of trees and shrubs, sometimes combined 

 with flowers or climbers, at other times with rockwork, and with 

 statues, fountains, basketwork, and so on. The trees and shrubs 

 are of good kinds, though not remarkable in this respect, having 

 been in part planted before the place was taken possession of by 

 Mrs. Lawrence ; but the flowering shrubs, including rhododen- 

 drons, azaleas, roses, &c., and the herbaceous flowers, are of the 

 most rare and beautiful kinds. The collection of green-house 

 and hot-house plants may be characterised as among the most 

 select and valuable in the neighbourhood of London. 



The numerous prizes which Mrs. Lawrence has received, for 

 some years past, from the Horticultural Society of London, evince 

 the excellence of the articles which she exhibits at their meet- 

 ings. The first prize which Mrs. Lawrence received from the 

 Horticultural Society was the silver medal for plants sent to the
