We were somewhere around Barstow, on the edge of the desert, when the
drugs began to take hold. I remember Martin Bonner
saying something like:

A putlog is the short piece of scaffold pipe with a flattened end that
ties the scaffolding into the newly built wall. The brickie will
leave the occasional joint unpointed as a putlog hole, and the
scaffolder can stick a putlog in it when he puts up the next lift of
scaffolding.

Obviously, when the scaffolding comes down at the end of the job,
someone has to fill in all the putlog holes.

Most informative. Thanks.
