This takes in a long narrow tract of country at no place more than 7 miles wide, and 

 for a considerable distance little above 3 miles wide. As the crow flies its length from 

 Stepper Point, outside Padstow Harbour, to Hayle is about 33 miles. Its boundary is the 

 road from Padstow through St. Columb to Blue Anchor, forming the western limit of the 

 Camel District. From Blue Anchor the line follows the turnpike road through Mitchell, Zelah, 

 and Scorrier to Redruth. At the mining town of Redruth it takes the Helston road across Buller 

 Downs, turning offat Nine Maidens, and at Praze Station joining the railway line to Hayle. 



Geologically this is an interesting district. From Stepper Point to the northern bank of 

 the Gannel at Newquay the soil is Lower Devonian, and the whole of that district has been 

 brought to a fine state of cultivation. West of the Gannel, coastwards from a line drawn 

 from the head of the creek to Perranporth, the country is Upper Silurian intersected by elvan 

 courses and the well known Perran Iron Lode. A little distance from the south bank of the 

 upper waters of the Gannel there are faint traces of a small deposit of limestone. Inland 

 from the line above indicated Lower Silurian cover portions of the parishes of Cubert, Newlyn 

 East, and Perran, while at St. Enoder the district takes in a small portion of the same rocks 

 which form a belt around Hensbarrow Hill. These two patches are separated by a continua- 

 tion of the Lower Devonian rocks, which sweep around the Perran branch of the Lower 

 Silurian to about Chapel Forth, west of St. Agnes Head. There they are replaced by beds 

 which have been provisionally classed as Cambrian. These are the oldest slates of the county, 

 and in the district under notice, save an unimportant deposit of Lower Silurian west of 

 Portreath, they occupy the coast-line from Chapel Forth to Godrevy. Inland they range to 

 Blackwater and Redruth, sweeping round the western side of Carnmarth and the northern 

 side of Cam Brea Granite Boss to Camborne, in which parish Lower Silurian are again ex- 

 posed and occupy the remainder of the district. 



Here perhaps better than in any other part of the county is one able to institute con- 

 trasts between the north and the south coasts. Placing this district against that which is to 

 follow, it will be found poor in those densely wooded valleys which open on the south coast 

 and afford shelter for a rich patchwork flora which has ' been " taken in in numbers " and 

 bound afterwards.' Here and there one happens upon a quiet sylvan oasis watered by a clear 

 stream, but on the whole the district answers to the description of the Devonshire wag who 

 thought Cornwall scarcely grew trees enough to supply timber for coffins for its inhabitants. 

 The downs of this district offer little to the botanist beyond the everyday species of the 

 county ; even in the rare weeds of cultivated land it is singularly poor, and where a marsh 

 occurs it is irritatingly restricted and yields few of those plants which are the pride of 

 paludal haunts south of the county's backbone. Its coast flora, with but few exceptions 

 to be presently noticed, is simply a thinning away of that of the Camel and Upper Tamar
