The word " economy" has latterly been used in various senses; the Germans give it a very indefinite signification.
Judging from its etymology and original signification, the Greeks seem to have understood by it the establishment and direction of the menage, or domestic arrangements.
Xenophon, in his work on economy, treats of domestic management, the reciprocal duties of the members of a family and of those who compose the household; and only incidentally mentions agriculture as having relation to domestic affairs. This word is never applied to agriculture by Xenophon, nor, indeed, by any Greek author; they distinguish it by the terms, georgic geoponic.
The Romans give a very extensive and indefinite signification to the word "economy." They understand by it, the best method of attaining the aim and end of some particular thing; or the disposition, plan, and division of some particular work. Thus, Cicero speaks of oeconomia causae, oeconomia orationis; and by this he means the direction of a law process, the arrangement of an harangue. Several German authors use it in this sense when they speak of the oekonomie eines schauspiels, or eines gedichtes, the economy of a play or poem. Authors of other nations have adopted all the significations which the Romans have attached to this word, and understand by it the relation of the various parts of any particular thing to each other and to the whole—that which we are accustomed to term the organization. The word "economy" only acquires a real sense when applied to some particular subject: thus, we hear of "the economy of nature," "the animal economy," and " the economy of the state" spoken of. It is also applied to some particular branch of science or industry; but, in the latter case, the nature of the economy ought to be pointed out, if it is not indicated by the nature of the subject.

I was very sickly and weak during the first years of my infancy, and was, as much as I can remember of myself, a very whimsical boy. Sometimes I learned with enthusiasm, and often found myself in such a kind of ecstasy, that I neither could see nor hear what passed around me. In these fits of thought I forgot playthings and playfellows; I was happy only in my own musings. I always preferred the company of little girls to boys. I was not ten years old when I presented them with some poetry and little verses, the effusions of my heated imagination; some of them fell into my hands in riper years, and after reading them over, I left off poetry altogether. I loved my first private teacher very much; I even can remember him now. My second teacher was a simpleton; he could never understand me, nor enter into my feelings. My antipathy to this man grew daily greater; I could not learn of him, nor could he teach me anything. At last, when in my thirteenth year, I got rid of him, and he being encumbered with debts, I gave him my saving-box when he left. Whether I did this for pity's sake, or joy to get rid of him, I did not know.

In both the kinds of land we have been considering [i. e., classes of very fertile soil, rich in humus], we have supposed the humus to be mild, or exempt from acidity. J Sour or acid humus totally destroys the fertility of a soil; sometimes, however, the soil contains so very small a portion of acidity that its fertility is very slightly diminished, and only with regard to some few plants. Barley crops become more and more scanty in proportion as the acidity is increased; but oats do not appear to be at all affected by it. Rye grown on such land is peculiarly liable to rust, and is easily laid or lodged. The grains of all the oereals become larger, but contain less farina. Grass which grows on these spots is, both in species and taste, less agreeable, and less suitable for cattle, than any other, although it yields a very considerable produce in hay. In fact, in exact proportion with the increase of acidity, is the decrease of the value of the soil...
