jetties, &c. &c.; and if the last-mentioned sum is insufficient, the commissioners have power to collect the twelve-penny duty for this purpose. The act to be in force for twenty-one years only, but its cessation is not to extinguish, or in any way to affect, the port duties which have been, by immemorial custom, paid to the corporation of Great Yarmouth.
That portion of the Bure River to which the above-recited acts relate, commences at Coltishall, where the Bure or North River Navigation terminates. Its course is very circuitous, in an eastwardly direction, by Wroxham Bridge, to the Ant River at Horning Marsh; from thence, by Weybridge and Runham Hall, to the town of Yarmouth, where it falls into the Yare. The distance from Coltishall to the mouth of the River Ant, is fifteen miles; from thence to the Thurne is two miles and a quarter; and from thence to time Yare is thirteen miles and a quarter. The Ant River Branch commences at the North Walsham and Dilham Canal, at Wayford Bridge, and takes a southwardly course, passing the Barton Broad, and the villages of Irstead, Ludham Bridge, to Horning Marsh, where it enters the Bure. Its length is nearly eight miles, and without locks. The Thurne River Branch commences at Hickling Broad, whence, passing through Heigham Sound, it takes a south-westwardly course by Heigham Bridge, to the River Bure, into which it falls near the village of Thurne. Its length is about seven miles, and level. In the township of Tunstall, about eight miles from Yarmouth, there is a navigable drain, of one mile in length, from the Bure to Tunstall Staith; and a little above Weybridge there is another, of half a mile in length, across Upton Marsh.
The Yare, or Wensom, has its source between the towns of Fakenham and Litcham, in Norfolk; whence, pursuing a south-easterly course by Sennowe Lodge, Westfield Park and Taverham Hall, to the city of Norwich, it there becomes navigable. From this place it continues, in a circuitous course, through low marshy grounds, by Hardly Cross, to near the village of Burgh, where it is joined by the Waveney; from thence its course is through Braydon Water, to Yarmouth, where the Bure falls into it; and from thence it takes a southerly course, running parallel with the coast, by South Town and Gorleston, to Yarmouth Roads.
