Then the great bales were carried on the backs of pack-horses 'by the ancient trackways over the Wiltshire and Hampshire Downs, which had been used before the Roman conquest, and thence through Surrey and Kent to the Medway ports by the Pilgrims' Way.' At the different ports the collectors of customs were ready to enter on their rolls the names of the merchants shipping wool, together with the quantity and description of wool shipped by each.[43] Some of the wool came to London itself, where many of the staplers had offices in Mark Lane (which is a corruption of Mart Lane) and was weighed for the assessment of the customs and subsidy at the Leadenhall.[44] In this business Thomas Betson was helped by Stonor's three assistants or 'prentices', as they call themselves, Thomas Henham, Goddard Oxbridge, and Thomas Howlake, for the last of whom he had a warm corner in his heart, because the young man was gentle to little Katherine Riche.

These men were sometimes at the Stonors' London warehouse and sometimes at their house in Calais, and they saved Betson a good deal of trouble, being experienced enough to oversee both the packing of wool in London and its sale in Calais.
To Calais the wool thus packed, and weighed and marked and assessed by the customs officer, was carried in the ships of Calais itself, or of the little ports on the east or south-eastern coast of England, many of which are mere villages today.

For ships put out not only from Hull and Colchester, but from Brightlingsea, Rotherhithe, Walberswick in Suffolk, Rainham in Essex, Bradwell, Maidstone, Milton, Newhithe, and Milhall.

In August 1478, the Celys were paying the masters of twenty-one different ships for the freight of their sarplers of wool after the summer clip.[45] All through the summer the shipping went on, and right up to Christmas; but during the winter months the merchants were mostly sending over fells or sheepskins, after the great slaughter of sheep and cattle which took place at Martinmas, when housewives salted down their meat for the winter and farmers made delivery of the fells and hides, for which the staplers had long ago bargained.

Very often merchants' letters and customs accounts give us the names of these doughty little ships and their cargoes.
