The subject of Mason-Marks has obtained some additional interest lately in consequence of the suggestions that they might be made useful towards ascertaining the dates of buildings. Living in a district rather remarkable for the goodness of its masonry, both in material and in workmanship, my attention had frequently been directed to the singular character of these marks, but it had never occurred to me that they might be made available for the purpose above mentioned until I read Mr. Godwin's letters on the subject in Vol. XXX. of Archseologia. Though I doubt whether these marks can be classified chronologically, so as to form an index for fixing the date of buildings, yet it is certainly desirable that those who have it in their power should contribute their mite towards such a collection as Mr. Godwin suggests, in order to a thorough investigation of the subject. It is with this object that I have collected the mason-marks on several buildings in the neighbourhood in which I live, the dates of which are pretty nearly fixed by written records or other extraneous evidence.
