used exclusively. Mr. Alexander W. Robertson, formerly
of Chelsea, Mass., assists her in creating artistic shapes.
The colored glazes or enamels which are used are especi-
ally meritorious. The decorations are incised and in
relief.  Mrs. Irelan has given this pottery the name
of Roblin ware, which is formed from the first syllables
of Mr. Robertson's name and her Christian name.
The mark is the word " Roblin," in conjunc-
tion with the outlined figure of a bear, impressed R 3N
in the clay.
Mr. Alexander W. Robertson was at one time con-
nected with his brother ir. Hugh Cornwall Robertson,
at Chelsea, Mass. The latter died at Dedham, Mass.,

DOYLESTOWN, PA.
Mr. Henry C. Mercer began experiments in the manu-
facture of art tiles about 1900 at Doylestown, Pa. The
common red clay of the vicinity is used, which is covered
with a heavy glaze. The decorative motives, such as the
conventionalized tulip, were suggested by the old iron
stove-plates and earthenware of the Pennsylvania Ger-
mans, which were produced in that section for more than
150 years. He has named his establishment the Moravian
Pottery and Tile Works.
Among recent styles attempted by Mr. Mercer are un-
glazed, smear-glazed, modelled, sgraffito and slip-decorated
tiles, many of the patterns being reproductions of mediae-
val designs found in England, Germany, and other parts
of Europe. He has also produced some large tile panels
