Caeredin: Gwahaniaeth rhwng fersiynau

Dyma’r cenadwri a gafodd y daearegydd Ray Roberts gan ei gydweithwyr yn yr Alban am rosod Rose Street, Caeredin (Bwletin 34):

:''Mike Browne came up with information from a web site."There are eight large pebble mosaics by Maggy Howarth. As well as foot traffic, they were designed to withstand the weight of delivery vans and service vehicles. The mosaics are around 2 metres across and each one is a different variation on the rose design. I found this on a web page trying “mosaic roses" : ‘mosaicists will know the difficulties of hand collecting legally in the UK, not to mention the backache. Cobblestone Designs has been importing stones from the Far East, China and India for several years, primarily for our own use’. So it looks as if the stone came from much further east than Eastern Scotland.''<ref>Bwletin Llên Natur rhifyn 35[https://www.llennatur.cymru/Content/Upload/Cylchgrawn35.pdf Bwletin Llên Natur rhifyn 35]</ref>
