Loams, as we have seen (p. 2), lie in between sands and clays: they are neither very wet nor very dry: not too heavy nor yet too light: they are very well suited to our ordinary farm crops, and they form by far the best soils for general farming; wheat, oats, barley, sheep, cattle, milk, fruit and vegetables can all be produced: indeed the farmer on a good loam is in the fortunate position of being able to produce almost anything he finds most profitable. In a loam district that does not {110} lie too high the land is generally all taken up, even the roads are narrow and there are few commons. The hedges are straight and cut short, the farm houses and buildings are well kept, and there is a general air of prosperity all round. Good elms grow and almost any tree that is planted will succeed. Loams shade off on one side into sand; the very fertile sands already described might quite truly be called sandy loams. On the other side they shade off into clays; the heavy loams used to be splendid wheat soils, but are now, like clays, often of little value. But they form pleasant, undulating country, nicely wooded, and dotted over with thatched cottages; the fields are less wet and the roads are rather better than on the clays. When properly managed they make excellent grass land. Chalky soils stand out quite sharply from all others: their white colour, their lime kilns now often disused, their noble beech trees, and, above all, the great variety of flowering plants enable the traveller at once to know that he is on the chalk. Many plants like chalk and these may be found in abundance, but some, such as foxgloves, heather, broom or rhododendrons cannot tolerate it at all, and so they will not grow.
