Hurd worked principally in the Chippendale style; he made some plates in the Jacobean and a few in the Ribbon and Wreath styles, but he died before the latter was much in use, and the former was really going out when he took up the making of plates. Judging from the appearance of his work, his first attempts were in the Chippendale style, and the few Jacobeans he made were done after he had attained considerable efficiency.
One of his earliest specimens was undoubtedly the plate of Edward Augustus Holyoke, the famous doctor of Boston, who lived to be one hundred years old, and who was but a year or two the senior of Hurd. In this plate he used a design which he evidently believed he could improve upon, and in which he felt there were good features, for we find a number of future plates of very similar design but much better execution. In the Holyoke plate the work is very crude, the lines are stiff, the drawing is poor, and the lettering of the motto and name are not good. An ugly scroll is placed under the name, and the festoon of cloth which is draped at the bottom of the frame and around the motto ribbon is especially poor; the shell at the base of the escutcheon which figures so often in future plates is here used, and the queer little flow of water from it would not be recognized as such were this the only specimen in which it occurs; the arrangement of the rose sprays, the form of the shield, and the employment of the shelly edge show a thorough study of the elements of this style. Very likely this design was copied in great part from some foreign example which had come into his possession.
In the Thomas Dering plate, which is the earliest plate dated and signed by an American engraver, this same design is improved upon; it is more compact in appearance, a little freer in execution, and the drawing is improved. The name is still not very well engraved, and top-heavy flourishes weigh down the capitals.
In the Theodore Atkinson plate the same design is still further improved upon; the flow of water from the scallop shell is here caught in a little bowl, a little additional flowery ornamentation is added, and the heraldic drawing is better. The name is again embellished with graceless flourishes.
The design seems to reach perfection in the Wentworth plate; every feature is markedly better, the water still flows out of the scallop shell, the same shaped shield is used and the motto is placed upon a graceful ribbon with ends which run off into fancy foliations. The name is neat in appearance, but still there are too many scrolls.
In the plate of Robert Hale of Beverly, the old festoon of cloth noticed in the Holyoke plate is seen again, and no motto is given. The name is fairly well engraved.
