Seventh Edition, Carefully Revised, With an Appendix, and Report from the Select Committee of the House of Commons, June 1823, with Extracts from the Evidence

by John Loudon McAdam

In what way do you make the watercourses at the sides of the road; I ask that question, having observed the farmers, in exercising their power of cleaning out their ditches, dig them to such a depth as to render them dangerous to be passed at night?—I always wished the ditch to be so dug as that the materials of the road should be three or four inches above the level of the water in the ditch, and to that point we endeavour to bring the farmers, but they are very unwilling to clean the ditches at any time when called upon, and when they do it, if they find vegetable mould in any quantity at the bottom of the ditch, they will prosecute their inquiry much deeper than is useful, or proper for safety.

Do you consider you have power by law, at present, for preventing that?—Yes; because the law says, they are to clean them out according to the directions of the surveyors.

In your experience have you found any impediment to the improvement of the roads, from a want of power in the proprietors of different navigations to lower their tolls for conveying materials?—I have found in the river Lea navigation, that the trustees have no power to lower their tolls, which were imposed by act of parliament upon merchandize, and therefore, it operated in a great measure as a prohibition to carry materials upon that river.

Do you consider it would be to the interest of the proprietors to allow materials to be carried on their navigations at a lower rate than they are empowered to allow by law?—Yes, if they could.

Do you know any similar instance as applicable to canals?—I don’t know an instance with respect to canal trusts, but there is an instance with respect to the Bath river at Bristol. No mitigation of the present rate of duty on that river can take place if objected to by any one proprietor, and therefore we have found great difficulty in carrying materials on the Bath river. In one particular place we have been entirely precluded from carrying any.

Have you found any impediment to the improvement of roads arising from the conditions upon which materials are permitted to be conveyed from one parish to another?—Yes; I found that in several cases in the Bristol district. One very strong instance occurred near Keynsham; we had a quarry close to the edge of one parish, and we could not carry the stones from it to the distance of ten yards, without the process of going to the magistrates.

Did you in that case make application to the magistrates?—I did intend to make application, but before I made that application, I found in the very next field, belonging to the same farmer, and in the parish where we required them, the necessary materials, and I was under the necessity of opening both the fields, to the detriment of the farmer’s landlord I am persuaded.

Do you know an instance of such an application as that to which you have alluded, having been made to the magistrates, and having been refused?—No, I do not.

Do you think that a great inconvenience and loss of time would be saved if that necessity of application was dispensed with?—It certainly is a great inconvenience, and creates a great deal of heart-burning in the country, and much dispute. I think the commissioners would very seldom be disposed to carry materials from one parish to another, unless for the general public good.

What depth of solid materials would you think it right to put upon a road, in order to repair it properly?—I should think that ten inches of well consolidated materials is equal to carry anything.
