The benefit to the inhabitants of this large City by such an important improvement, in all its various advantages of comfort, convenience, and economy, can scarcely be appreciated; and your Committee hope that the plan about to be tried in two separate parts of London will be found so far to succeed as to induce its adoption, at least in all the large streets of the Metropolis, observing, that they believe that it is a plan which Mr. MᶜAdam has for many years urged the adoption of, and, as constituting a part of his system, will be found mentioned in all his publications on the improved system of road-making. 20th _June_, 1823. MINUTES OF EVIDENCE. _Mercurii, 28º die Maij, 1823._ SIR THOMAS BARING, BART. In the Chair. _John Loudon MᶜAdam_, Esquire, called in; and Examined. You were formerly a magistrate, and commissioner of the roads in Scotland, were you not?—I was. When did you first turn your attention to road making?—I was a commissioner and trustee of the roads in Scotland from the time of my return from America in the year 1783; and I naturally turned my attention to it there, because they had begun about twelve years before to make the roads turnpike, and they were carrying them on with considerable activity when I returned from America; and it appeared to me at that time, and all the time I was trustee, that there was a great deal of money expended needlessly, and with very little effect, on the roads, and that of course turned my attention to the cause. I began then to travel through different parts of the country to inspect the different managements of different parts of the road, first in Scotland, and then I went into England. In the year 1798, I came to live in England, at Bristol. I have no documents to prove my travelling before I came to reside in England in the year 1798. In 1798 I began to make it a sort of business. Without saying to any one what my object was, I travelled all over the country in different parts. I have a list of such of those places I travelled to that I happened to keep memorandums of, but I cannot possibly say all the places I travelled to. How long were you occupied in travelling for the purpose of obtaining information for the construction of roads?—It was only occasional travelling of course. I had some other occupations and private affairs to look into. I began in the year 1798 to travel as often as I had leisure and convenience down to the time I took the charge of the Bristol roads, down to the year 1816, the beginning of 1816 or latter end of the year 1815.
