A packhorse, pack horse, or sumpter refers to a horse, mule, donkey, or pony used to carry goods on its back, usually in sidebags or panniers. Typically packhorses are used to cross difficult terrain, where the absence of roads prevents the use of wheeled vehicles. Use of packhorses dates from the neolithic period to the present day. Today, westernized nations primarily use packhorses for recreational pursuits, but they are still an important part of everyday transportation of goods throughout much of the developing world and have some military uses in rugged regions. History Packhorses have been used since the earliest period of domestication of the horse. They were invaluable throughout antiquity, through the Middle Ages, and into modern times where roads are nonexistent or poorly maintained. Historic use in England Packhorses were heavily used to transport goods and minerals in England from medieval times until the construction of the first turnpike roads and canals in the 18th century. Many routes crossed the Pennines between Lancashire and Yorkshire, enabling salt, limestone, coal, fleeces and cloth to be transported. Some routes had self-describing names, such as Limersgate and the Long Causeway; others were named after landmarks, such as the Reddyshore Scoutgate ("gate" is Old English for a road or way) and the Rapes Highway (after Rapes Hill). The medieval paths were marked by wayside crosses along their routes. Mount Cross, above the hamlet of Shore in the Cliviger Gorge, shows signs of Viking influence. As the Vikings moved eastwards from the Irish Sea in about 950 AD, it is likely that the pack horse routes were established from that time. Most packhorses were Galloways, small, stocky horses named after the Scottish district where they were first bred. Those employed in the lime-carriage trade were known as "limegals". Each pony could carry about in weight, spread between two panniers. Typically a train of ponies would number between 12 and 20, but sometimes up to 40. They averaged about a day. The train's leader commonly wore a bell to warn of its approach, since contemporary accounts emphasised the risk packhorse trains presented to others. They were particularly useful as roads were muddy and often impassable by wagon or cart, and there were no bridges over some major rivers in the north of England. About 1000 packhorses a day passed through Clitheroe before 1750, and "commonly 200 to 300 laden horses every day over the
