Reference has been made to the Wistaria on the bridge over one of 

 the ponds, and its surroundings of Rhododendrons and other flowering 

 shrubs must be seen to have any idea of the effect. One tree is especially 

 worthy of note, viz. Cedrus atlantica glauca, which is not only the most

Fig. 22 shows one of another series of ponds, having a small 

 island in the centre, on which the elegant Alnus laciniata imperialis 

 is a striking object, and for planting in a wet position this tree has 

 probably no equal for beauty. On these ponds the Villarsia ny?nphceoides

 Weeping Willow, varieties of Cornus, and other suitable plants, while

 Bog Myrtles, Myrica asplenifolia being the most ornamental and the 

 sweetest. 



Where there is sufficient space for a large plant by the side of water, 

 Gunnera manicata is unsurpassed ; its bold foliage is very imposing. 

 Several leaves at Wisley last year were over seven feet across. This year
