Much has been written about Irish and Scotch marks and the silver plate which was made in these two countries as distinct in character to that fashioned in England. The most authentic account, in handbook form, of Irish silver is that given in the " Guide to the Art Collections " in the National Museum of Ireland, an exceedingly useful book of reference written by Mr. M. S. D. Westropp, M.R.I.A., to whose courtesy we are indebted for the illustrations of Irish silver given in this volume. The first account of a Dublin Guild of Goldsmiths dates from the fifteenth century. In 1605, the Dublin Corporation ordered a Town Mark, which was to be a lion, a harp, and a castle. Then later three marks were used on Dublin plate, these being the harp, crowned, the maker's mark and the date letter : from 1730 the figure of Hibernia was added. As regarding Scotch marks Mr. Westropp tells that in 1457 the Edinburgh silversmiths were ordered to use a maker's mark and a deacon's mark and a town mark. Many " home connoisseurs " have in their plate chest spoons and other pieces marked with the triple-towered castle of Edinburgh. We learn, too, from the same authority, that not only was plate hall-marked in Glasgow with the arms of the city, but " plate appears to have been made in Montrose, St. Andrews, Stirling, Tain, and other towns." The mark of Glasgow has been described by many writers. Mr. Westropp, however, gives it concisely. It consists, he says, of " An oak tree, the trunk impaled with a fish, on the top of the tree a bird and to the left of the tree a handbell."
