92 THE WILD-FLOWERS OF SELBORNE 



orchis. In the early summer of 1898 the latter 

 appeared in extraordinary abundance on a small patch 

 of down-land in the writer's parish. There were 

 literally hundreds of plants. Not content with occupy- 

 ing the down, they invaded the debris of an adjoining 

 chalk-pit, and sprang up in every possible situation. 

 The following season it required a good deal of

But if in some few instances the disappearance of

 London at Fulham " might be seen the sweet-smelling 

 flag, and the yellow water-lily, and the scarce Carda- 

 'mine impatiens. The sweet - scented camomile was
