No extensive schemes were carried out in Rothesay during Bute's tenure of the provostship; but it is of interest to note that whereas the harbour had been greatly improved, and gas first introduced into the town, during the time (1829-1839) that his father was provost, he himself, during his term of office, made a large extension of the pier, and introduced the electric light. He also interested himself in the sanitary improvement of the burgh, and entertained the members of the Sanitary Congress, which met at Rothesay in 1898, at a garden party at Mountstuart. Following his own precedent at Cardiff, St. Andrews, and Falkland, he presented to the corporation a beautiful chain of office for the use of the provosts. The occurrence of Queen Victoria's diamond jubilee during Bute's provostship gave occasion for his further munificence; and in commemoration of the event he placed in the council-chambers a series of heraldic stained-glass windows. To each of the Town Councillors he presented a replica of the medal which he and the other provosts of Scottish burghs received at a special audience given to them by the {211} Queen. Bute gave pleasure to the councillors by reminding them that the Scriptural quotation on the obverse of the medal--"Longitudo dierum in dextera ejus, et in sinistra gloria"[12]--would probably be more familiar to them all in the rendering of the Scottish Paraphrase: In her right hand she holds to view A length of happy days: Riches with splendid honours joined Are what her left displays. Bute himself drafted the jubilee address from the corporation to her Majesty, and had it engrossed in facsimile after the original charter to the burgh of the year 1400 A.D., preserved in the British Museum. Sealed with the ancient seal of the burgh, and enclosed in a box made of the old oak beams of the drawbridge of Rothesay Castle, lined with cloth of gold, the address was, at Bute's instance, presented to the Queen by H.R.H. the Duke of Rothesay (Prince of Wales). It was one of the very few addresses on exhibition in London, where it aroused considerable attention and admiration.
