the position would include the beautiful North 

 American mocassin flower (Cypripedium specta- 

 bile) and other slipper worts, the scarlet cardinal 

 flower and its pale blue cousin (Lobelia cardinalis 

 and L. syphilitica), the huntsman's cups (Sarra- 

 cenia), in mild positions the Madeiran Orchis

 in their early stages. These increase by their

 the bear berry (Arbutus uvi-ursi) and the partridge 

 berry (Gaultheria procumbens), both charming 

 little creeping shrubs, are very suitable, and it

 Himalayan species G. tricophylla, which has

 bushes with its pretty clusters of pink and white 

 flowers.

 of a more natural kind, and the site for these is
