The VVelland District is a narrow strip of country on the north-eastern side of the county which is bordered by Leicestershire, Rutlandshire and Lincolnshire on the north and east, by the Avon district already described on the west, and by the district drained by the three districts of the Nene on the south and east. Its more precise boundaries are as follows : The VVelland rises at Sibbertoft (for some time the residence of the veteran botanist, the Rev. Miles J. Berkeley) from a spring near the vicarage about 600 feet above sea-level, and drains the parishes of Marston Trussell, East Farndon and Braybrooke, and then near Lubbenham separates the counties of Leicester and Northampton from that place to Market Harborough, Welham and Rockingham, the strata being cut down to the Upper Lias. Near this latter place Rutland succeeds Leicestershire, and the VVelland, with its extensive alluvial meadows, divides the two counties from Caldecott by Harringworth, Duddington, VVakerley (where it touches the Lincoln- shire limestone) nearly to CoUyweston, where a fault brings in the Upper Lias clay as far as to Stamford, where the Lincolnshire limestone again borders it, and Rutland is in turn dis- placed by the county of Lincoln, which the VVelland still separates from Northants in its sluggish course by Market Deeping, and at Kennulph's Stone near Croyland it becomes wholly a Lincolnshire stream. The extreme eastern border of the county to Low Borough Fen is formed by an imaginary line. To trace a separating water-parting in the low-level of the 65
