Page 311 - Wheat is extensively cultivated, and also a good deal of Indian corn: a kind of bean is, however, the staple article of food for the common labourers. The orchards produce an overflowing abundance of peaches, figs, and grapes. With all these advantages, the inhabitants of the country ought to be much more prosperous than they are.
Page 285 - Europe, nay, of the entire world, and sucks the hcartblood from nations, without a thought of justice towards them, without a shadow of lasting advantage for herself. It is impossible (he proceeds to say) that such iniquitous interference with the Divine order of the world should escape its rightful punishment; and this may perhaps overtake England even sooner than the countries she robs. Most assuredly a time awaits her, when all her riches of gold, iron, and coal will be inadequate to buy back...

With regard to the soil, as already stated, the experimental barley-field immediately adjoins the experimental wheat-field. The soil of both may be described as — "a somewhat heavy loam, with a subsoil of raw yellowish red clay, but resting in its turn upon chalk, which provides good natural drainage.
