1. Physical aptitudes of soile.g., since timber was still used almost entirely for smelting, iron works are found where timber is plentiful or where river communication makes it easily procurable. So the more fertile meadows of Gloucester and Somerset led these districts to specialise in the finer branches of the woollen trade. A still more striking example is that of South Lancashire. By nature it was ill-suited for agriculture, and therefore its inhabitants employed themselves largely in the cotton and woollen trades. The numerous little streams which flowed from the hills to the neighbouring sea gave plenty of water-power, and thus made this district the home of the earlier mills and the cradle of machine-industry.[32] The "grit" of the local grindstones secured the supremacy of Sheffield cutlery, while the heavy clay required for the "seggars," or boxes in which pottery is fired, helped to determine the specialisation of Staffordshire in this industry.[33]

2. Facility of Market.—The country round London, Bristol, and other larger towns became more specialised than the less accessible and more evenly populated parts, because the needs of a large town population compelled the specialisation in agriculture of much of the surrounding country; cottagers could more easily dispose of their manufactures; improved roads and other facilities for conveyance induced a specialisation impossible in the purely rural parts.

3. The Nature of the Commodity.—When all modes of conveyance were slow the degree of specialisation depended largely upon the keeping quality of the goods. From this point of view hardware and textiles are obviously more amenable to local specialisation than the more perishable forms of food. Where conveyance is difficult and expensive a commodity bulky for its value is less suitable for local specialisation in production than one containing a high value in small weight and bulk. So cloth is more suitable for trade than corn;[34] and coal, save where navigation is possible, could not be profitably taken any distance.[35]

The common commodities consumed, as food, fuel, and shelter, were thus excluded from any considerable amount of specialisation in their production.

§ 8. Turning from consideration of the attributes of goods and of the means of transport which served to limit the character of internal trade and determine the size of the market, let us now regard the structure of the market, the central object in the mechanism of internal commerce.

The market, not the industry, is the true term which expresses the group of organically related businesses. How far did England present a national market? How far was the typical market a district or purely local one?

The one great national market town was London. It alone may be said to have drawn supplies from the whole of England, and there alone was it possible to purchase at any season of the year every kind of produce, agricultural or manufactured, made anywhere in England or imported from abroad. This flow to and from the great centre of population was incessant, and extended to the furthermost parts of the land. Other large towns, such as Bristol, Leeds, Norwich, maintained close and constant relations with the neighbouring counties, but exchanged their produce for the most part only indirectly with that of more distant parts of the country.

The improving communication of the eighteenth century enabled the clothiers and other leading manufacturers to distribute more of their wares even in the remotest parts of the country, but the value paid for their wares reached the vendors by slow and indirect channels of trade, passing for the most part through the metropolis.

But while London was the one constant national market-place, national trade was largely assisted by fairs held for several weeks each year at Stourbridge, Winchester, and other convenient centres. At the most important of these the large merchants and manufacturers met their customers, and business was transacted between distant parts of the country, including all kinds of wares, English and foreign. Thus we had one constant and two or three intermittent avenues of free national trade. The great bulk of markets, however, were confined within far smaller areas.

In the more highly developed and specialised textile trades certain regular market-places were established of wide local importance. The largest of these specialised district markets were at Leeds, Halifax, Norwich, and Exeter. Here the chief local manufacturers of cloth, worsted, or crape met the merchants and factors and disposed of their wares to these distributing middlemen.
