Dig that treasure.

Amazing what you dig up sometimes.
Plot 18 has been dug by me several times and rotovated several times, but this came out today. Housebrick for size comparison purposes only, grass not included, warning this product may contain nuts if the squirrels have been around.....
The plot had a failed potato crop two years ago and was left fallow with additions of glyphosate for bindweed last year. What happened was that I did not dig since the spuds, so the ridges were still there and as I dug in one of the furrows the tip of the spade caught the bit top left in the picture.
I had to use a fence post and some bricks to lever this thing out, even after excavating over and around it.
"Never mind that stuff" said my furry supervisor, "just take me for a walk, NOW."
Today I dug from where she is sat to the bit nearest camera, where my undug row can be seen.
Just out of shot to the bottom left is my heeled in hedging from last year, the loose soil spread nearby is where the heeled in brambles were dug up from. The brambles have been distributed to strategic locations on the site fence, I love fruitful security.
Roughly where I stood to take the photo above, this thing had been resting since it was removed from my late mothers place before we sold the house.
Interesting history, it was once the parrafin store between the vinery and greenhouse-complex boilerhouse at an Edwardian gentlemans country estate
Makes a brilliant water tank, heavily galvanised, brass tap, just a shame the only inlet is front right.
So this is probably not its final resting place, best place is the other side of the two trap shed, but at least I can measure from this when I make a more robust base than breezeblock on bare soil. Possibly four short auger holes linked by a six inch deep plank edged trench and run some re-bar in three long U shapes between the holes to hold it all together once the concrete sets. Really do not want it to topple when full, anyone care to tell me the likely capacity in gallons? To aid estimators, at the front left corner the dark bit is two housebricks.
