It was a nice day on Sunday so we went down to The Little Salkeld Water Mill. We went there before looking for Long Meg and her daughters – I did mention it. We didn’t want Long Meg to think that, now we knew the way, we could drop in unannounced at any time, so we stopped at the Watermill, ate fruit loaf and drank coffee and Earl Grey tea. We are constantly conscious of the responsibilities we took on when we moved up here, you’ll notice.
The mill was working, so we went round to have a look at the water sloshing over the wheel. Mill wheels come in different shapes and sizes. Just over two thousand years ago, the Greeks started to take the idea seriously, and then the Romans had a go, then the rest of us chimed in and it wasn’t until the steam engine came along, water wheels had any real competition. Over this time, we had worked out that you can turn the wheel in three different ways. You can dip the bottom of the wheel in the river – cheap and cheerful, but not for serious work. You can raise the water so that it hits the wheel in the middle, that’s more expensive, more technical, but not too bad. Or you can raise the water even more and to pour it on at the top of the wheel.
This is high-tech stuff, as the taller the wheel, the more horse power it produces.
