#365daysofbiking Feeling flush

 

 

March 11th – I had time to spare so hopped onto the restored canal at Droitwich for a mooch. Just under the railway bridges in the last entry, I noticed this relic of the Ordnance Survey.

Flush Bracket 480 is one of a range of such brackets intended as mapmaker’s datums, the slots in which were for mounting surveying equipment at a known datum – in this case 28.7490m above sea level (the Newlyn Datum).

Now redundant as cartographer’s aids, these are more a historical curiosity than anything else, but I still get a buzz from spotting them in the wild.

April 13th – Hmm. Something is happening. Put on to this by local history wonk [Howmuch?], he told me in the week that he’d noticed that there was a crew drilling a borehole on the former marketplace in Brownhills.

Today, I swung past to take a look. He was right – a pile of fresh earth, and an access cover. Marked further towards the pedestrian bridge, a surveyor’s mark ‘BH2’ – presumably borehole 2, yet to be sunk. If that’s all the spoil to be removed, they’re not very deep.

Coupled with reports of surveying in the area of late, someone’s either taking measurements in preparation of building something, or there’s a problem underground, like a leaking drain. 

Whatever it is, it’s very much worth keeping an eye on.
