Loch Fad can easily be renoliod by fle Barone 
Road, or by the inland road to Kilchattan Bay. 
The near end of the Kirk Dam is about three- 
quarters of a mile from Rothesay, and the embank- 
ment fully 13 ee by either road. 
Loch Ascog. 
This loch is much smaller than Loch Fad, from 
which it is about half a mile distant at its south- 
west end. It is about a mile long, and scarcely a — 
quarter of a mile broad at the widest part. The 
shore of the upper or south-west end is of fine sand, 
and well known to local botanists as the habitat 
of a few interesting aquatic phanerogams, such as 
Lobelia Dortmanna. A large portion of the shore- 
line on both sides towards the north-east end is 
trap-rock, or stones and rough gravel. I did not 
observe many molluscs about or in tls loch; and 
the only forms worthy of special notice are Planorbis 
nautileus (type and var. albus), Zonites excavatus, and. 
Vertigo antivertigo. 
This loch can easily be reached by the inland road 
- to Kilchattan Bay, or by the road passing Folly 
House and Braeside. 
Loch Greenan, 
or Greenan Loch, as it is called by the people in the 
district, is quite a small sheet of water, being only 
about half a mile in length and scarcely two hundred 
yards wide. It is situated about one mile north-west 
of the Kirk Dam, and is easily reached by the Barone 
and St. Ninians Bay Road. | 
During summer the lower or south-west end is — 
overgrown with vegetation. There are white and. 
yellow water-lilies (Nymphea alba and Nuphar- 
luteum) growing in abundance, on the stems and
