string course

The string-course at the spring of the round head runs without a break from one to the other.

Over 17 this, a string-course runs uninterruptedly round the choir just below the windows.

You've but to slide down my leg to the parapet: and from the parapet you can jump right on to the string-course under the clock.

Near the modern lighthouse stands a tall, hexagonal tower, built of chalk in four stories, with a string course between each.

A moulded string-course, with gargoyles, runs below the parapet, which is a continuation of the plain coping on the western bays.
