Whitaker, in his "Loidis and Elmete" (1846), speaking of the impediments to commerce and manufactures in the Leeds district prior to the rendering of the Aire and Calder navigable, impediments which, he declares, "it will be difficult for a mind accustomed only to modern ideas and appearances to conceive," says:-- "The roads were sloughs almost impassable by single carts, surmounted at the height of several feet by narrow horse-tracks, where travellers who encountered each other sometimes tried to wear out each other's patience rather than either should risk a deviation. Carriage of raw wool and manufactured goods was performed on the backs of single horses, at a disadvantage of nearly 200 to 1 compared to carriage by water. At the same time, and long after, the situation of a merchant was toilsome and perilous. In winter, during which season the employment of the working manufacturer was intermitted, the distant markets never ceased to be frequented. On horse-back before day-break, and long after night-fall, these hardy sons of trade pursued their object with the spirit and intrepidity of a fox chase, and the boldest of their country neighbours had no reason to despise their horsemanship or their courage." There is the evidence, also, of Henry Homer, author of "An Enquiry into the Means of Preserving Publick Roads," published in 1767. He regarded the state of the roads and the difficulties of internal communication as among the chief reasons for the backward state of the country in the reign of Queen Anne (1702-1714), saying on this subject:-- "The Trade of the Kingdom languished under these Impediments. Few People cared to encounter the difficulties, which attended the Conveyance of Goods from the Places where they were manufactured, to the Markets, where they were to be disposed of. And those, who undertook this Business, were only enabled to carry it on in the {74}Wintry-Season on Horseback, or, if in Carriages, by winding Deviations from the regular tracks, which the open country afforded them an Opportunity of making.... The natural Produce of the Country was with Difficulty circulated to supply the Necessities of those Counties and trading Towns, which wanted, and to dispose of the superfluity of others which abounded. Except in a few Summer-Months, it was an almost impracticable Attempt to carry very considerable quantities of it to remote Places. Hence the Consumption of the Growth of Grain as well as of the inexhaustible stores of fuel, which Nature has lavished upon particular Parts of our Island, was limited to the Neighbourhood of those Places which produced them; and made them, comparatively speaking, of little value to what they would have been, had the Participation of them been enlarged.
