These rates in the first column only apply to the portion of canal and cuts already made; for the extension from the present termination at Garth Mill and Newtown, the rates in the second column are allowed.
A third act was obtained in 1821, entitled, 'An Act to enable the Company of Proprietors of the Eastern Branch of the Montgomeryshire Canal, to alter the Line of the Tannat Feeder; to make a navigable Cut from the Guilsfield Branch, to improve the same; and to amend Two several Acts respecting the said Canal.' The design of this act is to enable the proprietors of the Eastern Branch to alter the line of the Tannat Feeder, and to make a cut from the Guilsfield Branch, in order to improve the same. By this act also, the clauses whereby the two branches were to be consolidated, is repealed, and the consolidation is not to take place unless by consent of the proprietors of each. The point of commencement of the Eastern Branch, which before was doubtful, is now to be taken at the distance of thirty-five yards from the sill of the upper gate of the higher of the two Carreghofa Locks.
The length of this canal is twenty-seven miles, and was executed under the direction of Mr. J. Dadford, Jun. It has a lockage of 225 feet, in the main line from Llanymynach to Newtown. Commencing at Portywain Lime Works in Llanyblodwell Parish, in which place it unites with a branch of the Ellesmere Canal, it passes near the village of Llanymynach and crosses the Verniew River, joining at this place another branch of the Ellesmere Canal; thence running to Gwern-felu, where the branch to Guilsfield turns off, it proceeds to Welch Pool; after this it runs parallel to the Severn, past Beniew, through Garth Mill to its union with the Severn on the east side of Newtown. Its direction, by inspecting the map, will be found nearly south-west.
The estimate for the branch from Garth Mill to Newtown, was made. by Mr. Josias Jessop, and amounted to £28,268, including six locks of 8 feet each, and an aqueduct at Llyvior Brook; the cut to be 15 feet wide at the bottom, and 4 feet 6 inches deep.
The estimate for the cut from the upper end of the Guilsfield Branch to Pool Quay and widening the Guilsfield Branch, was made by Mr. G. W. Buck, at £9,140, 11s. 11d. including
