of the districtj which let at from 2s. 6c?. to 4s. per acre. The soils 
on this very extensive area vary, as may be supposed from their 
different mineralo^ical characters — that on the dun-stone, green- 
stone, and other trappean rocks being exceedingly fertile — loamy, 
free, but not light, letting on the average at 24s. per acre ; the 
rental ranging from 13s. to 70s. per acre ; whilst others, being 
clayey and more or less loamy, vary from 5s. to 20s. per acre. 
The average rental of the parishes of Lewanniclc, Lezant, South 
Petherwvn, South Hill, Linkinghorn, Stoke Climsland, and part 
of Callington, has been ascertained for the purpose of this survey 
to be about 18s. 6(Z. per acre.* The ordinary course of cropping 
is wheat, barley, turnips or potatoes, barley or oats, and grass- 
seeds laid down for two years ; the breadth of green crops on 
this rotation not exceeding 8 to 12 per cent. The corn crops 
yield about 16 bushels of wheat, 22 bushels of barley, and 
28 bushels of oats per acre. On the better cultivated farms the 
rotation is different, being wheat or oats, turnips and potatoes, 
barley, and seeds for two years, yielding from 20 to 24 bushels 
of wheat, 30 bushels of barley, 36 bushels of oats, and from 
27 cwt. to 30 cwt. of hay. The live stock in the district average 
from 20 to 35 breeding ewes, from 15 to 30 head of cattle, and 
10 pigs on 100 acres. 
23. We are now arrived at the banks of the South Channel and 
the borders of the Tamar, where we have a district of very con- 
siderable importance — from Calstock to the Rame by the Tamar 
on the east, from Calstock to Liskeard on the north, to the Looes 
on the south, bounded by the English Channel. The soil is 
generally light, free working and loamy, resting on red, grey, and 
variegated argillaceous slates, which are occasionally intermixed 
with sandy beds and with trappean rocks of "'dun-stones" and 
compact greenstones. Where the trappean rocks abound, the 
land is let from 30s. to 32s. per acre. A great breadth of this 
formation is found at Liskeard, striking through Menheniot, to 
the south of Quethiock, Landrake, St. Germans, and St. Stephens 
by Saltash. Immediately on the banks of the Tamar, in the 
parishes of Calstock, St. Dominick, Pillaton, and Landulph, 
there is not much depth of soil, and it is of a clayey character, 
abounding frecpiently in bands of clay, which intersect the slates, 
making the land wet and springy m the winter. The farms 
vary from 50 to 300 acres; the majority under 100 acres. The 
* We are indebted for much valuable information in this district to 
Edward Archer, Esq., Trelaske. He says the farms vary from 20 to 200 
acres — averaging about 100 acres. The enclosures are exceedingly small 
— in Lewannick, for example, consisting of 3.500 acres, there are no less 
than 1400 enclosures. This is a very common case in a great many other 
parishes.
