It is thus apparent that out of the 329,641 acres of cultivated land no less than 200,000, or more than half the whole area of the county, and about 60 per cent. of the total farming land, was still under the plough; this large proportion being at the time exceeded only in six English counties. The increase in permanent pasture has, however, been steadily progressing since the great fall in the price of cereals in the seventies; this being aided by the improvements in the means of communication throughout the country, which have tended to rob Hertfordshire of its original special advantage (owing to its proximity) in the matter of supplying the metropolis with corn and straw.
The subject of Hertfordshire agriculture cannot be dismissed without mention of the fact that the world-renowned agricultural station at Rothamsted, in Harpenden parish, founded and endowed by the late Sir J. B. Lawes, is included within its limits. This includes a laboratory, under a Director, situated on the west side of Harpenden common, and certain plots of land in the park at Rothamsted where agricultural experiments have been carried on for more than sixty years. The whole station is administered by a committee, mainly appointed by the Royal Society.
Fruit is grown only to a comparatively small extent in Hertfordshire. Very characteristic of the county are, however, the orchards (now for the most part more or less neglected) of small black cherries, known as Hertfordshire blacks, and also as “mazzards,” which are situated near the homesteads of most of the older farms. These are probably a cultivated variety of the wild black cherry of the neighbouring woods.
On the rich-soiled, low-lying lands of the Lea valley on the south-eastern side of the county are situated numerous market-gardens and nurseries. The growing of tomatos (at Harpenden), cucumbers, and grapes under glass is carried on in several parts of the county on a more or less extensive scale.
Elm, oak, beech, and ash form the most common timber-trees of the county, but the predominance of each kind in particular districts depends, as already mentioned, on the nature of the geological formation. The undergrowth in the woods, which should be cut every 12 or 13 years, consists mainly of hazel.
As regards the number of the larger and commoner kinds of domesticated animals, sheep in 1905 reached a total of 94,461, or about 234 to every 1000 acres; the average for England generally being 445 per 1000 acres. The prevailing breeds are the Hampshire Down, the South Down, and the Dorset; the latter being favoured on account of their early lambing.
Hertfordshire is not a great horse-breeding county, and in 1905 the number of these animals was only 15,070. Cattle numbered 38,636, and pigs 25,338. Shorthorns are the favourite breed of cattle among the farmers; and although in the chalk districts the soil is not specially well suited for dairy purposes, farms near the main railways despatch a considerable amount of milk to London. The number of horses was nearly the same as in 1901, but cattle showed an increase of nearly 2000 head. Sheep, however, had decreased by over 2000 and pigs by more than 6000.
