I usually visit Coleraine in County Londonderry several times a year.
There's a little book-shop tucked up a little street - Society Street - close to the parish church, which sells vintage books among other items.
On one occasion, I think in 2015, I found a small hardback written in 1927, five years after the formation of Northern Ireland.
It was by the Rev Canon Hugh Forde, with a foreward by Sir James Craig Bt (later 1st Viscount Craigavon), first Prime Minister of Northern Ireland.
I can only heartily concur with Lord Craigavon when he wrote:
In commending these brilliant sketches to the people of Ulster, and to visitors to our shores, I do so with all the more pleasure, although our native country is teeming with historical interest and is well supplied with ancient monuments, suitable books of reference are compartively few.
Canon Forde has done a public service in compiling so accurate a record of Olden Days, and providing an interesting glimpse of the life led by Ulstermen of bygone times.Seek it out if you can.
