Letter: Wherefore art thou so sad?

Sir: A "toe-rag" was the lowest grade of dock labourer in London. It was their job to level the grain in grain-bins. To protect their feet they wrapped rags round their boots.

It is sad that the denizens of Canary Wharf should be so unaware of the dialect spoken by the dock labourers and their descendants. Your building stands, metaphorically, on their shoulders.
