OK, so I was on my walk (treasure hunt, really) this morning ................
...(see

...and after I'd found that, I moved onto another search.
The gentleman who'd tipped me off about the tree carvings, also chatted about the Grand Union Canal itself, and how it used to be part of the main transport system for England before trains and lorries came into the frame.
Narrowboats, filled to the brim with all manner of things, such as coal, grain, wood, charcoal etc., used to travel down from the North of England to London.
Once they'd unloaded in London, they'd fill up with other goods and take them back up North.
The round trip would take weeks, but proved to be a lot faster and much more economical than transporting the equivalent amount of goods by road, bearing in mind that this was before the era of the motor vehicle or the train.
He mentioned that certain evidence of the "working" Canal can still be seen on many, if not all of the hundreds of brickbuilt Victorian bridges that span the Canal(s) throughout England....so I thought I'd go and have a look!
And here's the evidence!................
Can you see what it is yet?
Here's a closer view.......
Anyone any ideas?
I'll post the answer in about an hour....but if someone guesses right before that time, I'll buy them an orange for Christmas!
