 The house was huilt by Mr. Eustace Gurney in the autumn

 It is situated by the edge of Su Mon Broad, on a spit of land

THE BROAD 

 AND ITS IMMEDIATE NEIGHBOURHOOD 



Su lion Broad was, in comparatively recenf times, a large 

 sheet of open water (about 100 acres), but now il is overgrown 

 by reeds and ail kirids of aquatic végétation, so that there is 

 scarcely anv open water except in the channels which are kept 

 free for navigation. The greater part of tliis végétation con- 

 sists of Reeds (Arundo), Reedmace or Gladden (Typha), and 

 Bullrush or » Bolder •• (Scirpus) in pure growths as well as 

 mixtures of tlie three. The roots of the- Reed and Reedmace 

 are matted together to form a. floating platform, known localis- 

 as ••Hover-, which is often strong enough to bear a man's 

 weight. Il is theoutward growth of tins Hover which hasgra- 

 duallv choked the Broad. Where the water still remains com- 

 paratively open, or where Scirpus is dominant, there is abun- 

 dance of submerged or floating aquatic plants of which the most 

 couspicuous are the White Water Lily (Castalia), Bladderwort 

 (Uêricularia). Myriophyllum, Stratiotes and species ol'Pond- 

 weed (Potamogetori), The shores of the Broad are ill-defined, 

 consisting of low, levé] marshes, of which large areas are sub- 

 merged bv a verv slight rise of the water. The levé] of the 

 Broad oscillâtes rapidly accord ing to the amount of rain, the 

 direction and force of wind. and, to some small extent, in svm-
