Rotations. 
Eleven were the old Norfolk system — roots, barley or 
oats, seeds, wheat, from the following counties : — Lincoln (3), 
Norfolk (2), Berks (2), Gloucester, Hants, Hereford, and Salop. 
All descriptions of soil are specified from heavy to light. 
Nine examples similar to above, only that wheat and spring 
corn were interchangeable. From the above counties, also 
from Lancashire (2) and Notts., no soil was described as 
heavy ; “ medium ” to “ heath ” are given. 
Four examples of the four-course without taking wheat. 
Yorkshire (2) and Northumberland (2). Correspondents sup- 
plying these specified the following soils : — “ Good loam to 
stony clay,” “gravel,” “mixed,” &c. 
One Norfolk system in Surrey had no swedes nor any barley 
in the rotation ; it reads, “ Mangolds and potatoes, oats, ‘ seeds,’ 
wheat.” 
In the above twenty-five examples, “clover ” is specified only 
six times as being taken once in four years ; all the other cases 
“seeds,” “hay,” &c., is the turn mentioned in its stead. No 
special county or type of soil is, however, distinguishable 
where clover is mentioned. 
Six examples are practically the Norfolk system, except that 
peas, beans, vetches, and sainfoin, &c., replace part of the 
clover. These crops sometimes being used singly, sometimes 
in couples as “ beans and vetches.” 
One four-course from Wiltshire is as follows : — Wheat, 
barley, roots or clover, roots. 
Besides the above examples, which are mentioned as being 
practised by the correspondent, very many others say that the 
“ four-course ” is commonly used in the district by their neigh- 
bours. 
Five Years' Course. — Forty examples returned. (A few 
examples too doubtful to include.) 
The Norfolk or closely allied system with “ seeds” left down 
two years is sent in from the following nine counties : — 
Cumberland, Northumberland, Durham, Yorks., Lancashire, 
Cheshire, Lincoln, Notts., and Shropshire; all classes of soil 
being mentioned. 
The same system, i.e., the Norfolk, extended by taking two 
white straw crops, is mentioned twenty-five times, as follows : 
— Oats after wheat, nine times ; barley after wheat, five times ; 
wheat after oats, five times ; barley after oats, three times ; 
barley after barley, three times. 
These examples come from counties as far apart as Essex 
and Somerset, Hants and Yorkshire, Warwick and Norfolk, and 
every class of soil except chalk or fen is mentioned. 
Four examples where potatoes are taken as an extra crop 
once in five years, always after clover or “ seeds,” were sent in
