In his present profession, Mr. Thom's career may be dated from the commencement of the winter of 1827. Being employed at this time in the immediate neighborhood, he applied to Mr. Auld, of Ayr, who afterwards proved his steady and judicious friend, for permission to take a sketch from a portrait of Burns, with the intention of executing a bust of the poet. This is a good copy of the original picture by Mr. Nasmyth, and is suspended in the very elegant and classical monument, from a design by Mr. Hamilton, erected to the memory of the bard, on the banks of the Doon, near "Allowa's auld haunted kirk." The permission was kindly granted; doubts, however, being at the same time expressed, how far the attempt was likely to prove successful, Mr. Thom not being then known in Ayr. These doubts seemed to be confirmed, on the latter returning with a very imperfect sketch, taken by placing transparent paper on the picture. These occurrences happened on the Wednesday, consequently nothing could be done till Thursday, when materials were to be procured, and other arrangements made, before the work was absolutely begun. The surprise then may be conceived, on the artist returning on the Monday following with the finished bust. In this work, though somewhat defective as a likeness, the execution, the mechanical details, and the general effect, were wonderful, especially when viewed in connexion with the shortness of the time and the disadvantage of being finished almost from memory--the very imperfect outline, already mentioned, being the only _external_ guide. It was this general excellence that encouraged the proposal of a full length figure--a proposal to which the artist gave his ready assent, stating that he had wished to undertake something of the kind, but did not consider it prudent, without any prospect of remuneration, to hazard the expense both of the block of stone and the loss of time. On this Mr. Auld offered to procure any stone from the neighboring quarries which the artist might judge fit for his purpose. Several days elapsed in this search; in the meantime, the matter was rather laughed at than encouraged; and some apprehensions of failure, and exposure to consequent comments, being expressed, "Perhaps," said the artist, endeavoring to re-assure his friends, "I had just better try my _hand_ at a _head_, as a specimen o' Tam." This being agreed to, he returned to Crosby church-yard, where he was then employed upon a grave-stone. The day following happened to be one of continued rain; and, finding that the water filled up his lines; probably, too, thinking more on "glorious Tam," than on the _memento mori_ he was attempting to engrave, our artist resolved to take time by the forelock, and to set about the "specimen head" directly. Accordingly, pulling from the ruins of the church of Crosby a rabat of the door-way, as a proper material for his purpose, he sat himself down among the long rank grass covering
