the former transferred to a newly prepared bed but a short 

 distance north. Owing to peculiar conditions found necessary 

 for the proper cultivation of certain plants, it has proved ad- 

 visable to change the positions of the beds devoted to the 

 Poppy, Fumitory, Mignonette, Milkwort and Gentian fam- 

 ilies, their relative positions in the sequence, however, being 

 preserved. Rockeries have been provided for the rock-lov- 

 ing crucifers and saxifrages. The construction of the path 

 along the westerly ridge made necessary the transferral of 

 the bed given up to the Cactus family to a position opposite 

 its former one, thus furnishing better conditions for the 

 growth of these plants and ample opportunity for expansion 

 as the collection grows. One new bed was also prepared for 

 the Mimosa family, not hitherto represented here. 



For some time large masses of rock in some of the plots 

 have interfered considerably with the proper cultivation of 

 the plants in them. This rock was especially troublesome in 

 one of the large beds of the Thistle family, where an enor- 

 mous boulder obstructed one end. This was blasted and the 

 shattered rock removed to a depth of about two feet, being 

 replaced with top soil. The same treatment was applied to 

 one of the beds of the Mint family, to one of those of the 

 Foxglove family, and to that of the Potato family. 



Fruticetum. The number of species here has been con- 

 siderably increased, the collection now embracing 512 species, 

 represented by 1,037 shrubs. 



Salicctum. This group has been increased by the addi- 

 tion of a number of species of willows and poplars obtained 

 from the west nursery, where they have been accumulating 

 for several years. There are now under cultivation here 43 

 species, represented by about 125 plants. 



Arboretum. Few direct additions have been made to this 

 plantation. The collection now contains, including those 

 still in the nurseries and those native to the tract or previously 

 introduced, 217 species. 



Pinetum. The conifers in place are represented by 49 

 plants, comprising 16 species; 65 additional species are in 

 the nurseries.
