Seamus was renovating a place just up from Bayhead. Not a bad little town-house with a nice bay window. Enough space in the attic to make another small room. He needed a fit young cove like myself to swing a sledgehammer. He could shovel the debris out, bit by bit, in his own time, once I’d brought it down.

Seamus ran a Coastguard watch and took part in training the coast-rescue team. We got on. I did a couple of shifts with him, as an auxiliary, once I got my radio ticket. First day I learned to skin a rabbit. Learned a couple of other things from him as well. It was the done thing then, favour for favour between coastguards.

He issued me with the heavy sledge. He took up a dainty five-pound club for the tidying up. We were in our Coastguard boilersuits. Seamus pointed to the partitions which had to come down. Some of them were plasterboard but some were the older type of construction: plaster on a strapping of lath.

We got on with it. We had teacloths over our mouths and noses. Health and safety, late-Seventies style. Earlier in the decade you’d have had nothing at all.

We became possessed as we swung. The walls fell and the dust rose. I opened the skylight, which was about to be replaced by a larger Velux, and both of us gulped in air. It was all suddenly very quiet.

Some good wood here. Might be pitch-pine. You could smell the resin in the splintered bits. But we were horrified at how little time the demolition had taken.

‘Aye, it doesn’t take long to pull things down,’ Seamus said.

I thought of The Who and ‘Talkin bout my generation’. I also thought of Pete Townsend smashing up a beautifully built guitar, for dramatic effect. I was acting under instructions but I felt implicated.

I didn’t voice any of this. Instead I asked why the low attic was divided further, into stalls. I was thinking of the Arnol black-house. It wasn’t that different from other European peasant houses. The accommodation for animals was in touching and smelling distance. But this was an attic. It couldn’t have been for beasts.

He could see it all. The whole plan would have been simple. Tiers of bunks at both ends with a cubby-hole in the middle.

‘Look, that’s where the chimney’s bricked up. They’d have worked shifts, just like ourselves. That’s where they’d have done their cooking. One shift shoving some hot foot down, quick as they could so as not to lose their sleeping time. The kettle back on for the next folk. One lot would be out into the cold of the morning, the next fall into their warmed bunks. All the women packed tight in here, like herrings in a barrel.’

Seamus could decipher the system at a glance. But what would have happened from midnight Saturday to midnight Sunday? They wouldn’t have worked then.

‘I suppose half of the girls would walk out to their homes out of town. They didn’t think much of ten or fifteen miles back then. If the other half were from away, they’d have the bunks to themselves. Go together, arm in arm, to the kirk round the corner.’

He asked me to stay for a dram. But I wasn’t drinking then. And I wanted to get the dust out of my hair. Up the road, the olaid had a big fire on for the hot water. The new council houses still had an open fire but now you got the radiators off it.

I told her about the room with the bunks, over our fried chops. She came alive when I told her what Seamus said about the herring girls. This was where East and West Coast folk had come together. It all got joined up in the towns of Stornoway or Wick or up at at Baltasound, in Unst. The Baltic trade. That never really recovered from the First World War. She’d never seen the big days of it but she could say she’d caught the tail end.

She was on form.

My Broch grannie, her own mother, had been to Stornoway long before that Lewisman danced herself off her feet. ‘D’ye mind thon row o ornaments i the pre-fab i The Broch. Peterheid tae Yarmooth. Takin trains tae follow the fishin. Trying to save a few pound to send hame.’

Then it was saving up to get married. ‘Your grannie aye said she’d hid nae a baud life.’ Hard work but always amongst friends. She definitely mentioned Stornoway. It was a long time ago. Bayhead, Keith Street, Kenneth Street, Scotland Street – they were all full of attics like that. In between the barrel stores. Keith Street rang a bell. Now she thought of it, my grannie always said there was a lot of banter about being billeted so close to Al Crae, the undertakers.

My bit was done but Seamus asked me back. He’d finished the big sweep-up. The wallpapers were stripped, layers and layers of them. He pointed to the beams. The slants of light from the skylights were making them shine. There were waves and waves of lightly chalked names. Dolly MacDonald, Garyvard. Ishbel Mary MacLeod, 12 Habost. Milly Strachan, Inverallochy. Henrietta Stephen, Brightsea, Fraserburgh. And more and more.

I went home for a shot of my mother’s camera. A wee Olympus Trip. Easy to use. Some of the snaps were a bit blurred with the slow explosure. The olaid went through them all, a few days later. We never sighted the name she was looking for. Her eyes misted over just the same – a thing you didn’t see very often.
