Upon the whole, is it your opinion that there are any circumstances which justify an exemption from toll, on account of the breadth of the wheels?—I do not see any at all, for I think they are injurious in every sense, on account of the great weights they carry. Do you consider that injury is done to the roads, in consequence of the use of single shafts in waggons?—Very great. In what way?—In consequence of single shafts, the horses follow in one track, in the centre of the carriage; and the wheels also follow each other in other tracks, and cut ruts: if there were double shafts, they would naturally avoid former wheel-tracks, which would be less injurious to the road. Do you consider it therefore desirable to give encouragement to double shafts?—I do. Do you consider the watering of that road in any way injurious?—I consider that watering that road in summer, is very injurious. In what respect?—The water separates the stones, owing to the softening of the loam, and makes the road spongy and loose. At what periods do you consider it injurious to water the road for laying the dust?—Before May and after August. Have you not a practice of sometimes watering in winter, when there is no dust?—After the most careful sifting of the gravel, a small quantity of loamy dirt will unavoidably still adhere to the stones, and this loam, together with a glutinous matter which accumulates in the summer from the dung and urine of the cattle (which accumulation the summer watering has a tendency to increase) occasions the wheels to stick to the materials, in certain states of the road, in spring and autumn, when it is between wet and dry, particularly in heavy foggy weather, and after a frost; by which sticking of the wheels, the Whitechapel road is often, in a short time, dreadfully torn and loosened up; and it is for remedying this evil, that I have, for more than eight years past, occasionally watered the road in winter. As soon as the sticking and tearing up of the materials is observed to have commenced, several water-carts are employed upon these parts of the road, to wet the loamy and glutinous matters so much, that they will no longer adhere to the tire of the wheels, and to allow the wheels and feet of the horses to force down and again fasten the gravel stones; the traffic, in the course of four to twenty-four hours after watering, forms such a sludge on the surface, as can be easily raked off by wooden scrapers, which is performed as quickly as possible; after which the road is hard and smooth, the advantages of this practice of occasional winter watering have been great; and it might, I am of opinion, be adopted with like advantages on the other entrances into London, or wherever else the traffic is great, and the gravel stones are at times observed to be torn up by the sticking of the wheels.
