The English or round turnip is usually sown broadcast after some other crop, and large and valuable returns are often obtained. The Swede is sown in drills. Both these varieties are used for the production of milk. The chief objection to the turnip crop is that it leaves many kinds of soil unfit for a succession of some other crops, like Indian corn, for instance. In some sections no amount of manuring appears to make corn do well after turnips or ruta bagas. The MANGOLD WURZEL, a variety of the _Beta vulgaris_, is often cultivated with great success in this country, and fed to cows with advantage, furnishing a succulent and nutritive food in winter and spring. The crop is somewhat uncertain. When it does well an enormous yield is often obtained; but it often proves a failure, and is not, on the whole, quite as reliable as the ruta baga, though a more valuable crop when the yield is good. It is cultivated like the common beet, in moist, rich soils, three pounds of seed to the acre. The leaves may be stripped off, towards fall, and fed out, without injury to the growth of the root. Both mangolds and turnips should be cut with a root-cutter, before being fed out. The PARSNIP (_Pastinaca sativa_) is a very sweet and nutritive article of fodder, and adds richness and flavor to the milk. It is worthy of extended culture in all parts of this country where dairy husbandry is pursued. It is a biennial, easily raised on deep, rich, well-cultivated and well-manured soils, often yielding enormous crops, and possessing the advantage of withstanding the severest winters. As an article of spring feeding, therefore, it is exceedingly valuable. Sown in April or May, it attains a large growth before winter. Then, if desirable, a part of the crop may be harvested for winter use, and the remainder left in the ground till the frost is out, in March or April, when they can be dug as wanted, and are exceedingly relished by milch cows, and stock of all kinds. They make an admirable feed at the time of milking, and produce the richest cream, and the yellowest and finest-flavored butter, of any root with which I am acquainted. The good dairy farmers on the island of Jersey often feed to their cows from thirty to thirty-five pounds of parsnips a day, in addition to hay or grass. Both practical experiment and scientific analysis prove this root to be eminently adapted to dairy stock, where the richness of milk or fine-flavored butter is any object. For mere milk-dairies, it is not quite so valuable, probably, as the Swedish turnip. The culture is similar to that of carrots, a rich, mellow, and deep loam being best; while it has a great advantage over the carrot in being more hardy, and rather less liable to injury from insects, and more nutritive. For feeding and fattening stock it is eminently adapted.
