Full titles read: "1,700 feet below the Mersey - Lord Mayors of Liverpool & Birkenhead greet each other after last partition of £5,000,000 Tunnel is broken through."
The Mersey Tunnel, Merseyside.
M/S of a group of men and women walking down a wooden stairway, dressed in sou'westers and rain hats. M/S of them waving handkerchiefs at us as they stand in an open lift, going down; the Lady Mayor of Liverpool, Miss Margaret Bevan, is one of them.
M/S shows a man in a sou'wester standing at a rock face in a tunnel; he starts hacking away with a pickaxe. Cut to M/S of Margaret Bevan shaking hands with the Mayor of Birkenhead through the hole in the rock face - the Mersey Tunnel is broken through! (The Mayors have their chains on over their sou'westers.)
M/S of the two Mayors pose for the camera with another gentleman; they all have their hands joined on something I can't quite make out - a pickaxe? Brief shot of the other gentleman making a speech as the Mayors stand beside him; we can see the faces of workmen grinning in the background, looking through the hole.
Note: I love this one! For search purposes - Margaret Beaven / Margaret Beavan.
