I went for a short walk up the hill and discovered there are hundreds (if not thousands) of spider webs every square km. This one was horizontal, suspended between stalks of heather over a burn (small stream). It was just at the right angle to catch the sunlight.
Very nicely photographed
On a side note, spiders web (silk) was once used for cross-hairs in early theodolites.
It was on of the skills of early surveyors to replace ruptured cross-hairs in the field.
