8. Throughout the extensive empire of Rome, agriculture maintained a respectable standing, until the commencement of those formidable invasions of the northern hordes, which, finally, nearly extinguished the arts and sciences in every part of Europe. During the long period of anarchy which succeeded the settlement of these barbarians in their newly-acquired possessions, pasturage was, in most cases, preferred to tillage, as being better suited to their state of civilization, and as affording facilities of removal, in cases of alarm from invading enemies. But, when permanent governments had been again established, and when the nations enjoyed comparative peace, the regular cultivation of the soil once more revived.
9. The art of husbandry was at a low ebb in England, until the fourteenth century, when it began to be practised with considerable success in the midland and south-western parts of the island; yet, it does not seem to have been cultivated as a science, until the latter end of the sixteenth century. The first book on husbandry, printed and published in the English language, appeared in 1534. It was written by Sir A. Fitzherbert, a judge of the Common Pleas, who had studied the laws of vegetation, and the nature of soils, with philosophical accuracy.
10. Very little improvement was made on the theory of this author, for upwards of a hundred years, when Sir Hugh Platt discovered and brought into use several kinds of substances for fertilizing and restoring exhausted soils.
11. Agriculture again received a new impulse, about the middle of the eighteenth century; and, in 1793, a Board of Agriculture was established by an act of Parliament, at the suggestion of Sir John Sinclair, who was elected its first president. Through the influence of this board, a great number of agricultural societies have been formed in the kingdom, and much valuable information on rural economy has been communicated to the public, through the medium of a voluminous periodical under its superintendence.
12. After the example of Great Britain, agricultural societies have been formed, and periodical journals published, in various parts of the continent of Europe, as well as in the United States. The principal publications devoted to this subject in this country, are the American Farmer, at Baltimore; the New-England Farmer, at Boston; and the Cultivator, at Albany.
13. The modern improvements in husbandry consist, principally, in the proper application of manures, in the mixture of different kinds of earths, in the use of plaster and lime, in the rotation of crops, in adapting the crop to the soil, in the introduction of new kinds of grain, roots, grasses, and fruits, as well as in improvements in the breeds of domestic animals, and in the implements with which the various operations of the art are performed.
14. For many of the improved processes which relate to the amelioration of the soil, we are indebted to chemistry. Before this science was brought to the aid of the art, the cultivators of the soil were chiefly guided by the precept and example of their predecessors, which were often inapplicable. By the aid of chemical analysis, it is easy to discover the constituent parts of different soils; and, when this has been done, there is but little difficulty in determining the best mode of improving them, or in applying the most suitable crops.
15. In the large extent of territory embraced within the United States, there is great variation of soil and climate; but, in each state, or district, the attention of the cultivators is directed to the production of those articles which, under the circumstances, promise to be the most profitable. In the northern portions of our country, the cultivators of the soil are called farmers. They direct their attention chiefly to the production of wheat, rye, corn, oats, barley, peas, beans, potatoes, pumpkins, and flax, together with grasses and fruits of various kinds. The same class of men, in the Southern states, are usually denominated planters, who confine themselves principally to tobacco, rice, cotton, sugar-cane, or hemp. In some parts of that portion of our country, however, rye, wheat, oats, and sweet potatoes, are extensively cultivated; and, in almost every part, corn is a favourite article.
16. The process of cultivating most of the productions which have been mentioned, is nearly the same. In general, with the occasional exception of new lands, the plough is used to prepare the ground for the reception of the seed. Wheat, rye, barley, oats, peas, and the seeds of hemp and flax, are scattered with the hand, and covered in the earth with the harrow. In Great Britain, such seeds are sown in drills; and this method is thought to be better than ours, as it admits of the use of the hoe, while the vegetable is growing.
17. Corn, beans, potatoes, and pumpkins, are covered in the earth with the hoe. The ground is ploughed several times during the summer, to make it loose, and to keep down the weeds. The hoe is also used in accomplishing the same objects, and in depositing fresh earth around the growing vegetable.
