individual counties with the highest yields are Lincoln (Holland) and Isle of Ely, each of which average over 20 cwt. per acre.* Low yields are found in most Welsh counties, the lowest being Radnor, with little over 12} owt. to the acre. In Surrey, Hampshire, Worcester, Gloucester and Devonshire the yield is no higher than between 15 and 16 cwt. About one-half the wheat acreage of England and Wales (1,500,000 acres in 1925) is in the eastern and north-eastern divisions and the total production of these divisions in 1925 amounted to 713,000 tons, or 52% per cent. of the total wheat production of the country, which was 1,360.000 tons. Barley.—As in the case of wheat, by far the largest acreage of barley is found in the eastern and north-eastern divisions. The ratio of the barley acreage to total arable acreage (shown in Map VI) is greatest in Rutland and Norfolk with 29 and 26 per cent. respectively, but barley now occupies only 12 per cent. of the arable acreage of England and Wales, whereas in 1880 it occupied 15% per cent. Norfolk and Rutland show small increases In the proportion of barley to the total arable area as compared With 1880, and other important counties, e.g. Suffolk, Yorkshire (North Riding) and Northampton (with the Soke of Peter- borough), show little reduction. The heaviest yields are obtained In Lincoln (Holland) and Isle of Ely, with averages of 18 to 19 cwt. per acre, Cornwall coming next with over 17 ewt. Norfolk, Northampton and Rutland produce on the average rather under 15 cwt. The yield per acre in the northern division is higher than in any other, averaging 15} cwt. Of the total barley acreage (1,318,000 acres in 1925) 57 per cent. is found in the eastern and north-eastern counties, which with an average yield per acre of 15-2 and 16-3 cwt. respectively provided 59 per ont. of the total production in 1925 (598,000 tons out of 1,010,000 ons), Oats.—The growing of oats is much more widely diffused over the country than either wheat or barley and 174 per cent. of the arable area was devoted to this crop in 1925. As will be seen from Map VII it is grown largely in the north-western counties. Over 30 per cent. of the arable area in Cumberland, Westmorland, Lancashire and Cheshire, and also in Carmarthen, is devoted to oats, while in most of the Welsh counties the proportion lies between 25 and 30 per cent. Between 20 and 25 per cent. is found under oats in the northern group of counties and Derby and Stafford of the north-western, as also in Devon, Hampshire, Sussex, Glamorgan and Monmouth. Oats are grown least in Proportion to the arable area in the eastern counties from Lincolnshire southwards and in a narrow belt of land running westwards from the Wash to the Bristol Channel. Since the year 1880, the proportion of oats to total arable acreage has increased from 124 to 171 per cent. in England and Wales. The increase * The average yields per acre referred to in this chapter are averages of the ten years, 1915-24.
