London Labour and the London Poor, Vol. 2

by Henry Mayhew

The introduction of Mac Adam’s system of road-making into the streets of London called into existence a new element in what is accounted street refuse. Until of late years little attention was paid to “Mac,” for it was considered in no way distinct from other kinds of street-dirt, nor as being likely to possess properties which might adapt it for any other use than that of a component part of agricultural manure.

“Mac” is found principally on the roads from which it derives its name, and is, indeed, the grinding and pounding of the imbedded pieces of granite, which are the staple of those roads. It is, perhaps, the most adhesive street-dirt known, as respects the London specimen of it; for the exceeding traffic works and kneads it into a paste which it is difficult to remove from the texture of any garment splashed or soiled with it.

“Mac” is carted away by the scavengers in great quantities, being shovelled, in a state of more or less fluidity or solidity, according to the weather, from the road-side into their carts. Quantities are also swept with the rain into the drains of the streets, and not unfrequently quantities are found deposited in the sewers.

The following passage from “Sanatory Progress,” a work before alluded to, cites the opinion of Lord Congleton as to the necessity of continually removing the mud from roads. I may add that Lord Congleton’s work on road-making is of high authority, and has frequently been appealed to in parliamentary discussions, inquiries, and reports on the subject.

“The late Lord Congleton (Sir Henry Parnell) stated before a Committee of the House of Commons, in June, 1838, ‘a road should be cleansed from time to time, so as never to have half an inch of mud upon it; and this is particularly necessary to be attended to where the materials are weak; for, if the surface be not kept clean, so as to admit of its becoming dry in the intervals between showers of rain, it will be rapidly worn away.’ How truly,” adds the Report, “is his Lordship’s opinion verified every day on the macadamized roads in and around London! * * * * * * The horse-manure and other filth are there allowed to accumulate, and to be carried about by the horses and carriage-wheels; the road is formed into cavities and mud-hollows, which, being wetted by the rain and the constantly plying watering-carts, retain the same. Thus, not only are vast quantities of offensive mud formed, but puddles and pools of water also; which water, not being allowed to run off to the side gutter, by declivity, owing to the mud embankments which surround it, naturally percolates through the surface of the road, dissolving and loosening the soft earthy matrix by which the broken granite is surrounded and fixed.”

The quantity of “mac” produced is the next consideration, and in endeavouring to ascertain this there are no specific data, though there are what, under other circumstances, might be called circumstantial or inferential evidence.

I have shown both the length of the streets and roads and the proportion which might be pronounced macadamized ways in the Metropolis Proper. But as in the macadamized proportion many thoroughfares cannot be strictly considered as yielding “mac,” I will assume that the roads and streets producing this kind of dirt, more or less fully, are 1200 miles in length.

On the busier macadamized roads in the vicinity of what may be called the interior of London, it is common, I was told by experienced men, in average weather, to collect daily two cart-loads of what is called mac, from every mile of road. The mass of such road-produce, however, is mixed, though the “mac” unquestionably predominates. It was described to me as mac, general dirt, and droppings, more than the half being “mac.” In wet weather there is at least twenty times more “mac” than dung scavenged; but in dry weather the dung and other street-refuse constitute, perhaps, somewhat less than three-fourths of each cart-load. The “mac” in dry weather is derived chiefly from the fluid from the watering carts mixing with the dust, and so forming a paste capable of being removed by the scraper of the scavenger.

It may be fair to assume that every mile of the roads in question, some of them being of considerable width, yields at least one cart-load of “mac,” as a daily average, Sunday of course excepted. An intelligent man, who had the management of the “mac” and other street collections in a contractor’s wharf, told me that in a load of “mac” carted from the road to any place of deposit, there was (I now use his own words) “a good deal of water; for there’s great difference,” he added, “in the stiffness of the “mac” on different roads, that seem very much the same to look at. But that don’t signify a halfpenny-piece,” he said, “for if the ‘mac’ is wanted for any purpose, and let be for a little time, you see, sir, the water will dry up, and leave the proper stuff. I haven’t any doubt whatever that two loads a mile are collected in the way you’ve been told, and that a load and a quarter of the two is ‘mac,’ though after the water is dried up out of it there mightn’t be much more than a load. So if you want to calculate what the quantity of ‘mac’ is by itself, I think you had best say one load a mile.”

But it is only in the more frequented approaches to the City or the West-end, such as the Knightsbridge-road, the New-road, the Old Kent-road, and thoroughfares of similar character as regards the extent of traffic, that two loads of refuse are daily collected. On the more distant roads, beyond the bounds traversed by the omnibuses for instance, or beyond the roads resorted to by the market gardeners on their way to the metropolitan “green” markets, the supply of street-refuse is hardly a quarter as great; one man thought it was a third, and another only a sixth of a load a day in quiet places.
