Amongst some recently donated paperwork is this postcard sent in 1889 by Davies Brothers, Slate Merchants based in Porthmadog. The postcard asks Mr Lloyd Jones to hurry up with the delivery of slate from the Llwyngwern Quarry, which was in the Corris Valley. The quarry was rail connected to the Corris Railway, and slate would have been sent to Machynlleth for forwarding. The quarry is now the site of the Centre for Alternative Technology.
