92 THE USE OF CLOSED CASES 
procured abundantly in the woods in the neigh- 
bourhood of London. Of these I will mention 
a few. The common Ivy grows most beautifully, 
and can be trained over any part of the case, 
agreeably to the pleasure of the owner. The 
Primroses in early spring, will abundantly repay 
the labour of fetching them, continuing for seven 
or eight weeks in succession to flower as sweetly 
as in their native woods. The lovely Wood- 
sorrel, Oxalis acetosella , grows and flowers most 
freely when thus enclosed. This plant was in full 
flower when I was first honoured by a visit from 
the late Dr. Neill of Edinburgh, one who did 
more to advance the science of horticulture in his 
native country than any who had preceded him. 
Dr. Neill told me that he had never succeeded in 
causing this plant to flower at Canon Mills, where 
almost everything did well under his untiring 
skill. To the above plants may be added the wood 
Anemone, the yellow Pimpernel, the Veronica, the 
Stitchwort, and a host of other early-flowering 
plants. Mosses and ferns are great additions, but 
some of the latter are more valuable than others, 
in consequence of the longer duration of their 
fronds, — such as Lastrcea multiflora, spinulosa, 
and other allied species. There are likewise many 
common garden plants procurable at little cost — 
such as the lily of the valley, Solomon’s seal.
