Adding to my post of 26 Feb, I've found a few more verses to the Neath and Swansea Junction Canal. This gives me 5 of the 19 verses.
I've started a new thread here to track my progress on the rest and to fill in background detail. Note Elizabeth Davies's original title:
Lines on the Neath and Red Jacket Junction Canal
O! could I make verses with humour and wit, George Tennant, Esquire's great genius to fit; From morn until even, I would sit down and tell, And sing in the praise of Neath Junction Canal.
To his noble genius, great merit is due, The increase of traffic, he'll daily pursue; Employ to poor labourers, it is known full well He gave them by making Neath Junction Canal.

But I think that my duty I do not fulfill If I pass Mr Kirkhouse's very great skill. He exerted his talents as wonderf'lly well In that great undertaking; Neath Junction Canal
My song it is ended and now I will rest In hopes Squire Tennant will ever be blest. His goodness to the poor there is no tongue can tell Of his courage in making Neath Junction Canal.
I hope when he's dead and laid in his grave, His soul will in heaven be eternally saved; It will then be recorded for ages to tell, Who was the great founder of Neath Junction Canal.
