the more rampaut-growiug plants from mixing with and 

 over-running the more delicate and slow-growing alpines. 

 A large number of the plants in this part of the rock-garden 

 were gathered by Mr. Jenner during his Highland excur- 

 sions, the remainder consists of the best kinds of alpines of 

 other countries that were in cultivation at the time. This 

 was the first of this type of rock-garden constructed, so far 

 as I know, in Britain; and that it has answered the purpose 

 intended is witnessed by the fact that the majority of the 

 original plants, planted thirty-one years ago, are still in 

 perfect health and vigour. The raised beds were not 

 stoned, but were simply planted with dwarf-growing shrubs 

 or trees, many of which have been long since removed, as 

 they had outgrown their positions, and in their place groups 

 of lilies, ranunculus, anemone, and other showy plants 

 have been substituted. All the rest of the rock-work at 

 Easter Duddingston was designed by Mr. Gorrie. The best 

 portion is a charming piece of artistic rock-work lying south 

 of the original rock-garden, called by Mr. Jenner " Corrie- 

 more," as a memento of a botanical tour. This portion has 

 been laid out in a different manner from the rest. The 

 ground, instead of being raised, is excavated to a depth of 

 about 8 feet, the excavations forming a high bank all 

 round. Eough stones, placed firmly in the ground, support 

 the mass of soil forming the banks, and give the sides a 

 cliff-like appearance. A sloping narrow path runs round 

 both sides, and reaches the bottom, now laid out as a bog- 

 garden. The high banks afiord ample protection for the 

 growth of tender plants. Here such plants as Chamccrops 

 Fortunei, Aralia Sieboldi, Phormium tenax, Cordyline cnis- 

 tralis, Bamhusa falcata, Qucrcus (jlabra, Ilex latifolia, and 

 other half-hardy plants, resist the most severe winters. 



Adjoining " Corriemore " is an erection for the cultivation 

 of hardy ferns. Under cover of a projecting roof, large 

 blocks of sandstone are set up against a north wall, with 

 spaces for soil. In this hardy fernery most of the British 

 species with their varieties, and several Xorth American 

 species, are successfully cultivated. Some of the sandstone 

 blocks have numerous apertures about 2 inches in diameter 

 hollowed out, in which patches of Arenaria halearica are 

 grown for the purpose of draping the stones. In the damper
