| Disgrifiad | These envelopes contain a list of vessels at Port Penrhyn between the weeks ending 14 December 1840 and 09 October 1841. The details included in these lists are the name of the Vessels, to whom loading, quarry & mill slates, loaded or to be loaded. Some of these lists also have a summary of the slate brought down the port. The handwriting in these lists have become very faded and are very hard to read. |
