In the garden shed, I have an old tin of seed packets. I 'inherited' the tin from a house we lived in some years ago. The previous owner - Mr Treadwell, a keen gardener - had left it along with a glasshouse full of orchids and a shed full of tools.
We used the seed tin for our own seed packs, just placing them on top of the old packs.
I finally went through the tin the other day.
The label on one pack, right at the bottom of the tin, reads Carrot - Manchester Progress. Tasty and Tender. Deep Rich Colour. Yates Reliable Seeds on the front and, on the back, Price 12 cents. Good For Sowing Season 1969.
I guess I probably shouldn't bother sowing them.
(I presume Manchester Progess was a proprietary variety of Manchester Table.)
