Page:Remarks on the Present System of Road Making (1823).djvu/131

 Can you state whether the plan adopted on this road has increased or diminished the expense?—I think the expenses, by the last account, were rather within the expenditure of the former year, even including the new surveyor's wages. They had been in the practice of allowing about 32l. a week to the two surveyors as the ordinary expenditure; I directed the new surveyors not to exceed that sum upon any account whatever, including their own wages: but formerly they paid that sum, and paid the surveyor his wages at the end of the quarter or half-year in addition: therefore I consider the sum expended upon the road is rather within the former expenditure than otherwise, except with regard to two dangerous slips which took place at Swainswick-hill, which I consider as perfectly extra.

In the formation of roads under your management, to what shape do you give the preference; I allude to the convex shape or the flat?—I consider a road should be as flat as possible with regard to allowing the water to run off at all, because a carriage ought to stand upright in travelling as much as possible. I have generally made roads three inches higher in the centre than I have at the sides, when they are 18 feet wide; if the road be smooth and well made, the water will run off very easily in such a slope.

Do you consider a road so made will not be likely to wear hollow in the middle, so as to allow the water to stand, after it has been used for some time?—No; when a road is made flat, people will not follow the middle of it as they do when it is made extremely convex. Gentlemen will have observed that in roads very convex, travellers generally follow the track in the middle, which is the only place where a carriage can run upright, by which means three furrows are made by the horses and the wheels, and the water continually stands there: and I think that more water actually stands upon a very convex road than on one which is reasonably flat.
