On alighting at Snodland, we crossed the Medway in a ferry boat, and after a walk through the fields of about mile past the old church of Burham, we arrived at the works. The first objects of interest that attracted our notice were numberless rows of little sheds, under which the bricks are dried and which are termed hack grounds. These little sheds, about six feet high by three and half broad, cover upwards of seventeen acres of ground, and are situated between the brick machines and the kilns, and are intersected with lines of tramways. The whole estate is on a slope, falling gradually about one in eighty-five towards the wharf on the river, which fact considerably facilitates the economical working, as all the heavy material goes down hill, and in no case does any material or article have to travel over the same ground twice. At the top of the hill the clay is now dug, and is crushed and washed on the spot. The manager of the works, Mr. W. Varney, who was upwards of forty years in Mr. Cubitt’s employ, informed us that he had in the first instance selected the estate for Mr. Cubitt, and that the whole of the vast works had been erected and developed under his own immediate and residential superintendence. The clay is about 130 feet thick, and will last for a century to come. After being washed and crushed, the clay is conveyed in waggons or tramroads to the pugging

mills and machines, where, after going through a very simple process of squeezing, squashing, and pressing, it issues forth from the various machines, through the dies, in the shape of bricks, either solid or hollow, and tiles of all sorts, sizes, end shapes. These are generated, so to speak, by the machines with a wonderful rapidity, and conveyed by boys off the machines on to harrows, in which men wheel them into the drying hacks, under which they are stored to dry, previous to being stacked in the kilns for burning. All the brick machines are worked by one long shaft, 520 feet long, which receives its motion from the large engine of 220-horse power. This engine we found to be an old friend, being the one formerly worked at the Minories Station to wind up the endless rope on the Blackwall Railway, when the trains on that line were propelled by the well-known wire-rope. This engine, which is by Maudslay and Field, does nearly all the work of the place—pumping water, crushing clay, flint stones, &c., working the pug-mills, and all the brick, tile, and drain-pipe machines.

The latter articles are all made in the large building forming part of the engine- house. There are four floors, 400 feet long, on all of which drain-pipes, ornamental flower and chimney pots, tiles, &c., are made and dried, the beat from the boilers and the pottery kilns being turned off from waste into various pipes and chambers for heating the rooms, and so drying those goods which are not suitable for out- door drying in the hacks, previous to burning in the kilns. The number of moulds and wooden frames to receive the several articles when first formed, and when the clay is still plastic and liable to damage by handling, is really surprising. To give some idea, there was one pattern for hollow tiles of which Mr. Varney informed us there were in stock 80,000. The more elaborate articles made in this building are burnt in the kilns in the building; but the stronger and coarser goods are burnt in the out-door kilos with the bricks, and from each floor is a tram-road down an incline for waggons, leading direct from the pottery house, with the goods when dry, to the kiln where they are burnt, and the manufacture is so arranged that the heavy goods are made on the lower, and the lighter on the upper floors, so that in loading (as it is termed) a kiln of dry goods for burning, the heavy and stronger articles are at hand for the lower portion, and the more fragile goods for the upper tiers. After being burnt, the goods then ready for market and use are drawn out of the kiln on the opposite side to where they are loaded, and are placed on trucks on the line of rails immediately contiguous to the kiln doors, and are thence conveyed down the gentle incline of about 1 in 85, either to the wharf, to be at once loaded into barges and sent away, or to be stacked on the stock ground to await purchasers. With the single exception of the coal which is conveyed from the wharf to the kilns and engine-house there is no up-hill traffic, and even this is considerably assisted by the down pull of the loaded waggons, which also, as they go down to the wharf, help up the empty waggons back to the kiln. Thus much horse labour is done away with, and, instead of a large stud, only a very few are requisite to do the work. Some idea of the completeness of these carrying arrangements may he arrived at by the knowledge that there are upwards of three miles of tram and railroad on the works, with numberless turn-tables, weighbridges, etc. Nothing here is wasted; all the broken bricks, drain pipes, and even what few stones there are in the clay, are ground up to powder in a powerful mill worked by the large engine; and on being mixed up with the clay, form a material out of which some superior quality of goods are manufactured. “A never-failing supply of water is obtained front the river, which feeds a reservoir of some three acres in extent; and at the wharf, which is of the most substantial description, and stone-faced, some six barges may be loaded at once. At high tide there are fourteen feet of water at the wharf. Adjoining the wharfs are the cement works, consisting of engine and house, washing mills, some four kilns, with accompanying drying stoves and nine coking ovens.

Nothing strikes a visitor to these works more than the substantial character of everything on the estate. All is of the most solid construction, perfectly unlike any other brick works we ever visited. In most cases a few boards roofed in with tiles, forming a tumble down looking shed, forms all the building one sees, except the huge square masses of burning bricks, called clamps. At Burham everything is made as if to last for ever—all is Cubittian in its appearance, and everything is burned in kilns of the most approved construction. In addition to the large engine—our old Blackwall Railway friend—there are three others of various power; and all the necessary workshops, with room for the men, foremen’s cottages, &c., are in their places.

Near the top of the hill is a most substantial house, indeed quite a mansion, which overlooks the works. This is the residence of the out-door manager, Mr. Varney; and on viewing the whole field, with its various and numerous engines, buildings, tramways, kilns, wharves, &c., one cannot but see that here are what may be justly termed the model brick-works. Here are concentrated the results of near half a century’s experience and improvements. Everything is in the right place. Nothing superfluous. Every possible attention has been given to economize labour and material, and every advantage taken of the natural position of the estate. When in full work, between 600 and 700 men and boys are employed, and from 25,000,000 to 30,000,000 of bricks, besides tiles and pipes, can readily be turned out from the works; which, however, can be considerably augmented without any great outlay, or increasing the present steam power.”

“Evidently, despite his association with this company, by mid-century Ainslie entered into other agreements to manufacture his subsequent patents. In 1850 at the RASE meeting at Exeter, it seems he had formed another enterprise with William B. Moffatt, a manure manufacturer from London. Listing his address as Perryhill, Sydenham, Kent, Ainslie and Moffatt exhibited samples of manure and Ainslie’s newest tilemaking machines, “having a new mode of feeding, by the addition of one roller in connection with the other two”, 1. e. his patent of 1846 (RASE 1850, p.155). This raises a question of which machine patented by Ainslie did Dobson refer to as being popularly used for brickmaking prior to mid-century. In discussing the Ainslie machines improved by Thomas Cubitt and used at his large works at Burham on the Medway, Hermione Hobhouse illustrated the new roller machine patented in 1846, but cited an 1852 description of Cubitt’s works in The Builder. This article clearly mentioned the clay moving through a die: “The clay passes through two rollers out of the pug mill, by which means the air is driven out…011 runs in behind the die, to facilitate the passage of the clay through it” (The Builder 1852, p.285; Hobhouse 1971, p.313). This suggests that Ainslie’s earlier patented machines rather than his roller extrusion machine were more commonly known and adopted.”
