I needed a second look at that first photo before I realised how the camera angle has distorted the perspective.
What looks like a massive open space at the top of the picture is the Public Park (no rugby clubhouse, no pavilion, no path across to what is now Bellmans Road, and of course no avenue of "Coronation" trees) and the site of the High School isn't even in the picture.
The building top left is the Craigiebield and it looks as if work is just starting on the first of the cottages between there and the Navaar.
Fascinating!
