8. Tavistock 



This district consists of the three petty sessional divisions of Midland Roborough, 

 Tavistock and Lifton, being the greater part of the southern portion of the western or 

 Tavistock parliamentary division ; it contains about 230,106 acres, being about 228,224 acres 

 of land, inland water and saltmarsh, besides about 1,882 acres of foreshore and tidal water ; it 

 comprises all the 25 parishes of the Tavistock poor-law union, 5 out of the 6 Devon- 

 shire parishes of the Launceston union, 4 out of the 28 parishes of the Okehampton 

 union, and 7 out of the 20 parishes of the Plympton union, altogether 41 civil parishes, 

 one only of which is urban, and all of which are drained to the south coast except parts 

 of Lydford, Bridestowe and Sourton (which parts are drained by the West Okement river 

 towards the north coast) ; it is bounded on the west by the county of Cornwall, on 

 the north by the Torrington botanical district, on the east by the Torquay botanical 

 district, and on the south by the Plymouth botanical district. It is entirely inland, but part of 

 the south-western corner is washed with tidal water ; it contains the chief part of Dartmoor 

 Forest, including Cranmere Pool so-called, a centre on the moor not far from the sources of 

 several of the principal rivers of the county, the West Okement, the East Okement, the 

 Taw, the North Teign, the East Dart and the Tavy ; other streams in the district are the 

 South Teign, the West Dart, the Walkham, the Lyd, the Tamar (which forms the western 

 border against Cornwall for a considerable distance) with its tributaries, the Carey, the 

 Caudworthy Water, the Ottery (on the north-west), the Meavy and the Thrushel ; about 

 2 miles south of Cranmere Pool the moor ascends at Cut Hill to 1,981 feet above sea- 

 level.

The south-western part of the district belongs to the Upper and Middle Devonian 

 system, the north-western to the Carboniferous, and the eastern part is chiefly Dartmoor 

 granite ; several Greenstone patches mostly running in lines from west to east traverse the 

 Devonian part, and some others of an irregular outline traverse the Carboniferous part ; several 

 mineral veins and stream tin occur in the granite part. 



The climate of the district is illustrated by the following tables, which have been ob- 

 tained as explained under the Barnstaple district : —
