24 alk b amounting to 150,000 acres. Most counties show relatively little change, small increases being sufficient to meet the growing demands of the local population. But the expansion of the urban districts has brought about a notable extension in the areas where potatoes are grown for sale to other districts and this is accentuated by the reduction in the potato acreage in some counties, a reduction which is particularly heavy in Cumber- land, Devon, Gloucester, Somerset and Wales. In the western potato district the increase is small, amounting to about 8,350 acres in Lancashire and 1,350 acres in Cheshire. But in the eastern counties, Lincoln has increased its potato area from 35,500 to 104,000 acres and Cambridge (with the Isle of Ely) from 7,500 to 37,500 acres, the group of counties comprising Lincoln, Cambridge, Huntingdon, Bedford and Norfolk now having a total area of 182,000 acres under potatoes as compared with 55,000 acres in 1878. The highest yield per acre of potatoes is secured in Lanca- shire, where during the past 10 years the yield has averaged 7 tons to the acre. In Norfolk, Lincoln, the Isle of Ely and Stafford yields are between 64 and 7 tons and in Yorkshire (East Riding), Kent, Middlesex, Salop, Worcester, Northumber- land and Cheshire, from 6 to 64 tons. The remaining counties have average yields of less than 6 tons to the acre. Of potatoes more perhaps than of any other crop (except hops) can it be said that high yields are secured in the areas where the acreage is greatest, and low yields where it is least. The commercial production of potatoes has become centralised in those districts where conditions are especially favourable to high yields and it is probable that were it not for the comparatively heavy transport charges in relation to the value of the crop, the area of potatoes, outside the two districts already indicated. would be even further reduced. Of the total area of 493,000 acres of potatoes in 1925, some 63 per cent. lay within the three divisions comprising the eastern, north-eastern and north-western counties, while of the total production of 3,214,000 tons in that year these divisions provided 2,128,000 tons or over 66 per cent. Although this is the total estimated production on land coming within the agricultural returns, there is of course a large production on allotments and in private gardens. No estimate can be made of the latter, but the output of allotments in 1925 was put at 550,000 tons on the assumption that about one-half the area of allotments is devoted to this crop and that the average yield is about the same as on agricultural holdings. In the above estimates, the production both of early and main crop potatoes are included. With regard to early potatoes, the chief producing areas are Cornwall, Bedford, Kent, Cheshire, Lancashire and Lincoln (Holland). In 1925, it was estimated that there were 55,000 acres of first early potatoes on holdings in England and Wales with a total production of 233,000 tons.
