[A]ll this wonderful culture has entirely developed in the second half of the nineteenth century. Before that, it was quite primitive. But now the Paris gardener not only defies the soil—he would grow the same crops on an ashphalt pavement—he defies the climate. His walls, which are built to reflect light and to protect the wall-trees from the northern winds, his wall-tree shades and glass protectors, his frames and pépinières have made a real garden, a rich Southern garden, out of the suburbs of Paris. He has given to Paris the 'two degrees less of latitude' after which a French scientific writer was longing; he supplies his city with mountains of grapes and fruit at any season; and in the early spring he inundates and perfumes it with flowers. But he does not only grow articles of luxury. The culture of plain vegetables on a large scale is spreading every year; and the results are so good that there are now practical maraîchers who venture to maintain that if all the food, animal and vegetable, necessary for 4,500,000 inhabitants of the departments of Seine and had to be grown in their own territory (3,520 square miles), it could be grown without resorting to any other methods of culture than those already in use—methods already tested on a large scale and proved to be successful.
