The Ouse District This area is bounded on the western side by the Cherwell district, which reaches from near Evenley to Hinton-in-the-Hedges, by Greatworth to Preston Capes ; and on the north by the Nene district from which it is separated by a line which is traced in an easterly direction to the parishes of Farthingstone and Litchborough (which it leaves to the north), Cold Higham, Tiffield Cover and Gayton Copse. Leaving Stoke Bruerne to the south, it just takes in the villages of Roade and Hartwell, when it touches the Buckingham border between the latter village and Hanslope. The counties are separated from Grafton Regis to Cosgrove by the Tove, which has cut down to the Upper Lias clay, and from this point along the southern side the county boundary of Buckingham limits the district by Cosgrove, Old Stratford, Passenham, Wicken, Syresham and Brackley. Near this pleasant town it just touches the county boundary of Oxford until it reaches the Evenley road. Strictly speaking this district is composed of the drainage of two streams — one, the Tove, which rises from the high ground in the neighbourhood of Preston Capes, passes by Maidford and Blakesley to Towcester (where it meets another branch 61
