The estimated selling value of the total production of crop! 
grown in the 2,725 acres of glasshouses in England and Wales if 
1925 was about £4,800,000. Tomatoes are by far the most 
important crop, nearly all the returns including some quantity 
of this crop. On the basis of the distribution of output as show? 
in the returns received, the yield of tomatoes in 1925 was estimate 
at about 47,000 tons, valued at £2,350,000; of cucumbers almost 
50 millions, valued at £750,000; and of grapes 1,500,000 Ibs: 
valued at £130,000; other fruit and vegetables being estimated 
at £250,000. Chrysanthemums, roses and carnations wert 
valued at £200,000, £250,000 and £85,000 respectively, and 
including other cut flowers, bedding or decorative plants, &c- 
the estimated total value of flowers, etc., grown under glass wa 
about £1,350,000. These are only approximate estimates and 
afford merely a rough indication of the importance of variou 
crops grown under glass. 
Information was also sought on the special inquiry forms 
regarding the numbers of workers employed in glasshouses ant 
it seems probable that there is a total of roughly 18,000 worker 
regularly employed in glasshouses in England and Wales. 
The average value of the output per acre as shown by the 
returns was £1,770, but there were appreciable variations from 
district to district. Essex and Hertford, which include the 
greater part of the Lea Valley area, had an average output of 
£1,890 per acre, and West Sussex, which includes the Worthing 
area, as much as £2,220. Middlesex returned £1,590 worth © 
produce per acre under glass, Kent £1,275 and Lancashire £1,625 
The cropping of glasshouses varied considerably in these 
districts. In Essex and Hertford about 60 per cent. of the total 
value of the output was in the form of tomatoes, 15 per cent 
cucumbers and 15 per cent. flowers, mainly roses, leaving about 
10 per cent. for other crops. In West Sussex about 20 per cent 
of the value of the output was in the form of grapes, and 30 pe! 
cent. cucumbers, with less than 25 per cent. tomatoes. Thi 
area also had 15 per cent. of its output as flowers, the great bulk 
being chrysanthemums. Mushrooms and beans were also grow!’ 
in appreciable quantities. Middlesex had about 40 per cent. ©’ 
its output as tomatoes, about 15 per cent. cucumbers, 5 pel 
cent. grapes, 5 per cent. forced vegetables, mint, etc., anc 
35 per cent. flowers and plants. The cropping in Kent was 
fairly similar to that of Middlesex, about 65 per cent of thé 
output being fruit and vegetables (tomatoes accounted for abou! 
45 per cent., cucumbers 10 per cent., and grapes and strawberrie 
about 5 per cent. each), and flowers and plants accounted fo 
35 per cent. Lancashire had the largest proportion of flower* 
of these counties, with 40 per cent., and plants accounted fo 
15 per cent., leaving only 45 per cent. for fruit and vegetables 
of which tomatoes accounted for about 35 per cent., cucumber 
5 per cent. and lettuce 5 per cent.
