The roots live many years. We know a single root, in St. Lawrence county, N. Y., from which we ate pies and tarts twenty-two years ago, and which is now so vigorous as to yield more than a supply for two families through the season. The only care it has ever had, has been liberal supplies of well-rotted manure. The seed stocks have generally been broken off. They should always be, unless you wish to raise seed, then save one or two of the strongest. New crowns come out on the sides, from year to year, until each plant will cover a considerable space. The one mentioned, as being twenty-two years old, has never been moved during the whole time. It is not the giant kind, but the leaves are large and long. Rhubarb has a better flavor and requires much less sugar, by blanching. This is best done by placing an old barrel, without a bottom, over the hill as it begins to grow. The leaves will grow long, with white tender stems. Use it when the leaves are half or full grown, as you please.
RICE.
This, in its value to the world as an article of food, is next to Indian corn. It is the main article of diet for one third of the human race. It is produced only in certain parts of the world, and its cultivation is so simple and easy, and so much a department of agriculture by itself, that we omit directions for growing it. The ravages of the rice-weevil, so destructive to rice lying in bulk, are prevented by the application of common salt, at the rate of half a pound to the bushel.
ROCKS.
We frequently find, on some of our best land, large boulders, very hard, and too large to be removed, with any team we can command, and which would be in the way, in any place to which we might remove them. The best way to get rid of them, when it can be afforded, is to burn or blast them into pieces small enough to be easily handled. When this can not be afforded, the best method is to make an excavation by the side of them, deep enough to let them sink below the reach of the plow, and allow them to fall in, being careful not to get caught by them.
ROLLER.
This is quite as indispensable to good farming and gardening as any other tool. It serves a great variety of useful purposes. The first is to pulverize soils. No man can get a full crop on a soil not made fine on the surface, however rich that soil may be. It is often the case that land needs rolling two or three times before the last harrowing and sowing the seed. Another purpose is, on all light soils, to place the soil close around the seeds after they have been covered. When this is not done, seeds will vegetate very unevenly, and, in dry weather, some of them not at all. Another advantage of rolling a field-crop is the greater facility and economy with which it can be harvested. It makes a level, smooth surface, sinking small stones out of the way of the scythe or reaper. Rolling makes grass-seed catch, when sown with a spring-crop. All beds of small seeds—as onions, beets, carrots, parsnips, &c.—should be rolled after planting. It will so smooth the surface, that hoeing and cultivating can be done without injury to the plants. The rows are also much more easily seen while the plants are young. Any crop will grow better and larger by not being too much exposed to the action of the atmosphere on its roots. When the soil is coarse, part of the seeds and roots are greatly exposed to the action of the atmosphere, and this exposure is very irregular. The roller so crushes the lumps and fills up the openings in the soil as to cause the atmosphere to act regularly on the whole crop. Few farmers stop to think that the pressure of the atmosphere on their soils is fifteen pounds' weight on every square inch, and that, hence, the air must penetrate to a considerable depth into the soil; and where the soil is coarse, the air enters too freely, and acts too powerfully for the good of the plants. Rollers are made of wood, iron, or freestone. For most purposes, wood is best. A log made true and even, or, better, narrow plank nailed on cylindrical ends, are the usual forms. From eighteen inches to three feet in diameter is the better size. Iron or stone rollers, in sections, are best for pulverizing soil disposed to cake from being annually overflowed with water, or from other causes.
ROOT CROPS.
It is important that American farmers learn to attach much greater importance to the culture of roots. The potato is the best of all roots for feeding; but, as the yield has become so light in most localities, and the demand for it for human food has so greatly increased, it will no longer be grown extensively as food for animals. Farmers must, therefore, turn their attention to beets, carrots, and parsnips. Reasonable tillage will produce one thousand bushels to the acre of beets and carrots, and two hundred more of parsnips. These roots, raw or cooked, are valuable for all domestic animals. A horse will do better on part oats and part carrots, or beets, than upon clear oats. For milch cows, young stock, and fattening cattle, and for sheep and fowls, they are highly valuable. With the facilities now enjoyed, they may be raised at a cheap rate. Plant scarlet short-top radish-seed in the rows, to shade the vegetating seed and young plants, and to mark the rows, to facilitate clearing and stirring the ground, while the plants are very young, and using the most approved root-cleaners, and the same amount of food can not be grown at the same price in any other crops.
