According to lore, and sometimes in fact, these farms were refuges for children who lived in cities and towns, to which they would be sent during summer vacation to spend some time on a farm with relatives, perhaps learning something of ancient virtues and values. Such farms have mainly gone with the wind, so to speak nowadays. Most farming for the market, whether on family farms or on company or corporation farms, is more or less highly specialized. Many farms today have no farm animals at all. The old-fashioned barn has often been dispensed with entirely.
Vegetable gardens are probably no more common on large farms than they are in the suburbs.
Machinery has long since replaced most animals for motive power on the farms, and the machinery has become much larger and usually much more highly specialized in function than it used to be. A family farm is distinguished from others, if at all, by the fact that most of the work is done by a single family and that the family lives on the land. Even when there is some diversity in the produce, it is still done on a commercial scale usually. In sum, farming for the market has become commercialized. Actually, most government programs enacted over many years have been devised to affect farming for the market.
