[110] “Twenty-one oz.” and even “fifteen oz.” glass is used in the cheaper greenhouses.
[111] It is reckoned by measuring the height of the front and back walls and the length of the two slopes of the roof.

[113] Growing peas along the wall seems, however, to be a bad system. It requires too much work in attaching the plants to the wall. This system, however, excellent though it may be for a provisory start for gardeners who have not much capital to spend, is not profitable in the long run. The gardeners with whom I spoke in 1903, after having made some money with these light greenhouses, preferred to build more substantial ones, which could be heated from January to March or April.
[114] I take these figures from the notes which a Belgian professor of agriculture was kind enough to send me. The greenhouses in Belgium are mostly with iron frames.
[115] A friend, who has studied practical horticulture in the Channel Islands, writes me of the vineries about Brussels: “You have no idea to what an extent it is done there. Bashford is nothing against it.”
[116] A quotation which I took at random, in 1895, from a London daily, was: “Covent Garden, 19th March, 1895. Quotations: Belgian grapes, 4d. to 6d.; Jersey ditto, 6d. to 10d.; Muscats, 1s. 6d. to 2s.; and tomatoes, 3d. to 5d. per lb.”

[118] Out of them, 27,000 acres are grown in the fruit orchards, between the apple and cherry tree, so that the total area under fruit orchards and small fruit was reckoned at 308,000 acres in 1908.
