I don't see why the nineteenth century should have been any different from others in that respect.

Well, true that! But I guess--hmmm. I guess it was just one of the clearest examples of it I've seen.

The marijuana carpenters
Are a most special breed
With their grins and red eyes
And their motley supplies

Their skills are not learnt
For new cupboards or shelves
It's for sweet Mary Jane
That they take up the plane

and so on....
