Darlington, Gateshead, Hartlepool, Stockton, Sunderland, South Shields, Sedgfield, Stanhope, Staindrop, and Wokingham. As the map will show, we have traced out eleven drainage districts, the first four of which correspond to the Cheviot-land vice-county[1] of Watson's Cybele Britannica, the second four to his southern division of Northumberland, which we may call Tyne-land, and the last three to the county of Durham. In round numbers we may say the area of Cheviot-land is 800 square miles, of Tyneland 1150 square miles, and of Durham 950 square miles; and we would ask the special attention of our readers to these vice-counties, as we intend to give a separate list of the plants of each, or, to speak more accurately, to give, under each species, the initial letter C, N, and D of the vice-counties in which it grows. The districts which we have defined are as follows:—
1. Cheviot-land vice-county.
1. Tweed and Till district.
2. North-eastern district.
3. Aln district.
4. Coquet district.
2.Tyne-land vice-county.
5. Wansbeck district.
6. North Tyne district.
7. South Tyne and Allen district.
8. South-eastern district.
3. Durham (vice) county.
9. Derwent district.
10. Wear district.
11. Tees district.
We give, in the first place, a table, showing the distribution of the one hundred and eight boreal species through the eleven drainage districts.
- ↑ Mr. Watson, in Cybele Britannica, divides Britain into one hundred and twelve of these vice-counties.
