Emily Dickinson
(calligraphy is from Dickinson's The Soul selects Her Own Society, My LifeClosed Twice Before Its Close and Presentiment)
Emily Dickinson
The soul selects her own society,
Then shuts the door;
On her divine majority
Obtrude no more.
Unmoved, she notes the chariot's passing
At her low gate;
Unmoved, an emperor kneeling
Upon her mat.
I've known her from an ample nation
Choose one;
Then close the valves of her attention
Like stone.
I never saw a Moor
My life closed twice before its close;
It yet remains to see
If immortality unveil
A third event to me,
So huge, so hopeless to conceive,
As these that twice befell.
Parting is all we know of heaven,
And all we need of hell.
Presentiment---is that long shadow---on the lawn---
Indicative that sun goes down---
The notice to the startled grass
That darkness---is about to pass---
J Blakeborough & Sons Ltd - clock controlled gate valve (1920's)
An unusual water valve arrangement incorporating a clock-controlled unit that opened or cut the water flow at predetermined times. This type of automatic valve was made by J Blakeborough & Sons Ltd during the 1920’s / 1930’s and designed to be placed at remote locations where a supply of water is needed for a number of hours each day. This valve was set to automatically open at 6am and close at 6pm and it was only necessary for someone to visit once a fortnight to rewind the clock.
The opening/closing mechanism was hydraulically operated whereby at the set time mains water would be admitted to the pistons to open or close the valve’s gate. This particular valve was designed by engineer E. W Dixon of Leeds and supplied to the Pateley Bridge R.D.C. in North Yorkshire.
