 of water. The outlet, which flow from this arm at its southern eiul. has 

 beeome so thoroughly ehoked up with vegetation at its beginning that the 

 water has grown almost stagnant ami the lake flora is gradually working- 

 its way ui> tlie stream. Fig. 1 shows part of this arm in the left fore- 

 ground and the lilies at the entrance to the outlet. With the exception of 

 this arm the lake vegetation is most lu.xuriant near the southwest shore.

At some places around the lake, notably in the same arm. the bul- 

 rushes are followed by the cat-tails (Typha latifoliai with sedges and 

 grasses on the shore beyond. This is shown in Fig. 1. at the left. On
