 *wheeled waggons, which would justify their total exemption from tolls?—None at all.

Does the answer you have given to the Committee relative to the effect of great weights, apply equally to roads made with gravel, as well as broken stone?—I mean it to apply to all well-made roads, whether of gravel or of other materials.

You mean after the road is smooth and solid?—Yes.

But with regard to a new road, are you not of opinion that the materials are crushed and worn out by a great weight?—Yes; no doubt that is so on a new-made road, and one of those waggons with the wheels made conical, would crush a greater proportion of stone than it ought to do.

Do you not conceive that the state of the turnpike roads would be improved by not allowing any waggons to carry more weight than four ton?—I don't know that that would make any great difference, under good management. I think the defect lies in a want of science in road-making.

John Loudon M'Adam, Esquire, called in; and Examined.

In your evidence last week, you stated that less improvement had taken place in the roads in the neighbourhood of London than in any other district, to what causes do you attribute this circumstance?—I consider the principal cause to be the small extent of the trusts, and the peculiar situation of London, which increases the bad effects of the division into very small trusts.

What are the particulars of the situation to which you allude?—The situation of most of the roads near London is very low, difficult to be kept free from water, the traffic is very great both in weight and number, and therefore requiring more skill, as well as more care and attention, than the other roads of the kingdom; the material found near London for making the roads is
