Q: Passage: In 1877 the price of British-grown wheat averaged 56 shillings and 9 pence a quarter and for the rest of the nineteenth century it never reached within 10 shillings of that figure. In 1878 the price fell to 46 shillings and 5 pence. In 1886 the wheat price decreased to 31 shillings a quarter. By 1885 wheat-growing land declined by a million acres (4,000 km²) (28½%) and the barley area had dwindled greatly also.  Britains dependence on imported grain during the 1830s was 2%; during the 1860s it was 24%; during the 1880s it was 45%, (for wheat alone during the 1880s it was 65%.)
