The exact method of Tilling the soil in any particular case must be determined by many circumstances. Light soils are handled differently from heavy soils; and much depends also upon the season of the year in which the Tillage is done. In all ordinary soils, the effort should be made to work them deep, so that there is a deep reservoir for the storage of moisture and a large area in which roots can work. Subsequent Tillage throughout the growing season is performed very largely for the purpose of keeping the top of the soil loose and fine so that the moisture from beneath cannot pass off into the atmosphere. This loose layer of soil, extending two or three inches from the surface, may itself be very dry; but it breaks up the capillary connection between the lower soil and the air, and thereby prevents evaporation. This surface layer of loose, mellow soil is often spoken of as the earth-mulch. It answers much the same purpose as a mulch of straw or leaves in interposing a material between the moist soil and the air through which the moisture cannot rise. If this mulch is repaired as often as it should be, weeds cannot grow; but the object of the Tilling is more to make and maintain the mulch than to destroy weeds. The surface should be Tilled shallow in the growing season as often as it tends to become compact or encrusted. This will be after every rain, and usually as often as once in ten days when there is no rain. The tools to be used for this surface Tillage are those which will comminute or fine the soil most completely without compacting it or leaving it in ridges or in furrows. In garden work, a fine rake is the ideal thing; whereas in field work, some of the wire-tooth weeders or smoothing harrows are excellent. In fields which are hard and lumpy, however, it will be necessary to use heavier and rougher tools.

In order to break down hard clay soils, one must exercise great care not to work them when they are wet; and also not to work them very much when they are dry. There is a time, shortly after a rain, when clay lumps will break to pieces with a very slight blow. At this time it is well to go over them with a harrow or a rake. After the next rain, they can be gone over again, and before the end of the season the soil should be in fine condition. An excellent way of breaking down clay land is to plow or spade it in the fall and allow it to weather in the winter. In such cases the land should not be raked or harrowed, but allowed to lie rough and loose. Very hard clay lands sometimes run together or cement if handled in this way, but this will not occur if the land has stubble or sod or a dressing of manure, for the fibrous matter will then prevent it from puddling. Lime sown on clay land at the rate of twenty to forty bushels to the acre also has a distinct effect in pulverizing it. This may be sown in fall, or preferably in spring when the land is plowed.

One of the most important ways of ameliorating land is to work vegetable matter into it so as to give it humus. Soils which are loose, black and friable contain much of this vegetable mold. In many cases the chief value of stable manure is to add this humus to the soil. Many soils need humus more than they need plant-food, and hence stable manure gives better results in those cases than commercial fertilizers. The farmer secures the humus by plowing under stubble and sod, and occasional green crops.

TOMATO. The early fruits are very easily grown by starting the plants in a greenhouse, hotbed or in shallow boxes placed in windows. A pinch of seed sown in March will give all the early plants a large family can use. When the plants have reached the height of two or three inches they should be transplanted into 3-inch flower pots, old berry boxes or other receptacles, and allowed to grow slow and stocky until time to set them out, which is from May 15 on (in New York). They should be set in rows four or five feet apart, the plants being the same distance in the rows.

Some support should be given to keep the fruits off the ground and to hasten the ripening. A trellis of chicken-wire makes an excellent support, as does the light lath fencing that may be bought or made at home. Stout stakes, with wire strung the length of the rows, afford an excellent support. A very showy method is that of a frame made like an inverted V, which allows the fruits to hang free; with a little attention to trimming, the light reaches the fruits and ripens them perfectly. This support is made by leaning together two lath frames. The late fruits may be picked green and ripened on a shelf in the sun; or they will ripen if placed in a drawer.

One ounce of seed will be enough for from twelve to fifteen hundred plants. A little fertilizer in the hill will start the plants off quickly. The rot is less serious when the vines are kept off the ground and the rampant suckers are cut out.

TOOLS of many kinds, and well chosen, are one of the joys of a garden.

There is great satisfaction in a well-made, clean tool which does its work well. Keep the tools bright. They should be under cover, and in place, when not in use. A cupboard may be built by the rear porch, or in the barn or carriage house. See that the cupboard is in a dry place.

Various Tools have been mentioned in the preceding pages, and other useful kinds are shown in the article on _Weeds_.

TRANSPLANTING. This operation the gardener calls in one instance "pricking out." This means taking young seedling plants from the seed box as soon as they are large enough to be handled--usually when the first "rough" leaves have developed--and replanting them in other boxes or pots, either singly or at a greater distance apart than they were when in the seed boxes. The term is used in the operation of setting out plants from the hotbed, frame or house to the garden; also in removing shrubs or trees. Transplant on a cloudy day, and just before a rain, if possible.

TRIMMING is a term which is ordinarily confounded with pruning (which see). The word "Trimming," however, should be restricted to the shaping of the trees and not to the thinning of the tree or to pruning for wood, fruit or other special object. Trimming is only one of the means of pruning. Trimming is mostly used in the case of hedges. It is also used to keep evergreens in shape. Many ornamental plants are also Trimmed into various forms, although it is a question if such Trimming is usually wise. Fruit trees should be pruned, as a rule, rather than Trimmed: that is, they usually should be allowed to take their natural form, the pruner taking out the superfluous wood and keeping them within manageable bounds.

TROPaeOLUM. See _Nasturtium_.

TUBEROSE. The Tuberose requires more heat to grow to perfection than it is usually possible to give here in the North. If planted in the border they will not start into growth until the ground has become thoroughly warm--usually after the middle of June,--making the season before frost too short for their perfect growth and flower. However, if started in loose soil or moss in a warm room or on benches of a greenhouse, the roots will soon start from the tuber and make a fine growth. If planted out in June with a good ball of roots they are likely to bloom before frost. If any danger of frost is feared they may be lifted into pots or boxes and taken into the house, when they will bloom without a check. As with other bulbs, a sandy soil will suit.

TUBEROUS BEGONIA. A large bed of these covered with crimson, pink, white, or yellow flowers, ranging from 2 to 4 and even 6 inches in diameter, some double, some single, is a striking sight. Yet such a sight is not uncommon about the large eastern cities where the Tuberous Begonia is now used somewhat for bedding.

Our interior summers are more trying, and so far, few in the west have succeeded so well with the Tuberous Begonia as a bedding plant. It makes a fine summer-blooming pot-plant, however, for the greenhouse or window, and with due attention to its requirements, it may be used as a bedding plant. It properly falls under greenhouse plants in its requirements.

C. L. Allen, writing of its culture in his work on "Bulbs and Tuberous-Rooted Plants," says: "The principal point learned in regard to its culture is, that it must be treated as a plant and not as a bulb.

The enthusiastic florist, seeing the many good qualities of the plant, has led amateurs to believe it could be treated as a bulb, and planted out in the same manner as the gladiolus or tigridia and kept dormant during the winter in the same manner. This is a great mistake, as the tubers will not endure as long a period of rest and cannot be exposed to the air for a long time without seriously injuring their vitality. The tubers must be kept in dry earth or sand, until they show signs of growth, which will be not later than the first of March; then they may be started into rapid growth. After the eyes are fully developed the tubers may be divided: each eye will make a plant. Then they are treated in all respects like greenhouse plants, and grown on until the proper season for their planting out. This is not before the first of June, as Begonias are quite sensitive to cold nights, but not at all to heat. At that time the plants should be fully 6 inches in height and proportionately strong. Such plants will make a grand display the entire season, rather delighting in great heat."

[Illustration: Tuberous Begonia, single.]

In starting the tubers in March, they should be placed in moist sand or moss in a temperature of 60 to 65, either in the greenhouse or window.

After the buds are well started the tubers may be divided as pointed out, or planted whole. They prefer a rich, rather sandy soil. When they are well under way give them all the light and air they will bear, and keep them close to the glass to avoid "legginess" and to insure a firm, sturdy growth. A week before planting them out they should be given abundance of air and light to "harden off" the plants preparatory to setting them in sun and wind.

The beds should be in a somewhat sheltered place where they will be partially shaded from the hot midday sun. Let the soil be well enriched with old manure or humus and thoroughly worked over to a depth of one foot. During dry periods the beds will need watering from time to time; but never water them when the sun is shining full on them, or the foliage may be scorched. A mulch of leaf-mold or old manure will be helpful in keeping the soil moist and the roots cool.

Before frost the tubers should be carefully taken up and gradually dried in the shade, after which they are to be placed in dry sand or earth, in shallow boxes, and kept till time to start them in the spring. They should be kept in a cool place, secure from frost and away from stoves or heating pipes.

For amateurs it is better to recommend buying bulbs of the several colors, instead of attempting to grow them from seeds, which are extremely small and require early sowing, warmth and close attention.

TULIPS are hardy and easy to grow. The advice given under _Bulbs_, _Crocus_ and _Hyacinth_ applies to Tulips. They may be forced for winter bloom (see under _Window-Gardens_). The garden bed will last several years if well cared for, but most satisfactory bloom is secured if the old bulbs are taken up every two or three years and replanted, all the inferior ones being cast aside. When the stock begins to run out, buy anew. Plant in October, 4 to 6 inches deep.

[Illustration: Tulip as a pot-plant]

TURNIPS and RUTABAGAS are usually a fall crop, from seed sown in July and early August, although many kitchen gardens have them from spring sown seed. The culture is easy. Sow in drills 12 inches apart. They will become edible in from six to eight weeks. They are cool-weather crops, and the tops stand much frost. If maggots bother, do not raise them on the same land again for three or four years. Bordeaux mixture repels the flea-beetles. One ounce will sow 150 feet of drill.

VARIETIES. It is usually one of the first desires of the intending planter to inquire about Varieties. It is one of the secondary things to be considered, however, for the first thing to do is to prepare the land, to determine whether one's soil and site are adapted to the plant in question, and to discuss other matters of a general nature. When all the fundamental things are settled, then the question of Varieties, which is a special matter, may be taken up. Although the selection of Varieties is a very special matter, it is nevertheless essential to success or satisfaction in the growing of any plant.

It should first be considered that the selection of Varieties is very largely a personal matter. The man should grow the Varieties which he likes. This is especially true in the selection of Varieties for the home grounds, in which case the market ideals enter very little into the problem. Having satisfied one's own mind as to what kinds of Varieties he would like, he may then inquire of the neighbors and of experts if those Varieties are adapted to the soil and climate. If he intends to grow for market, he should canvass the market demands thoroughly before choosing the Varieties. The lists of Varieties in books, bulletins, and seedmen's catalogues are hints, not rules. As a general statement, it may be said that the only way to determine the best variety for one's own conditions is to experiment. There is intense satisfaction in the experimenting itself. The best lists of Varieties are those which are recommended for some specific purpose, and which represent the combined opinions of many expert growers. It is rare that one man's judgment should be final, particularly with respect to fruits or plants which are grown in general outdoor conditions. Under glass a gardener can make his climate and conditions, and therefore he can adapt his conditions to his plants. The experiment station test usually represents but one man's opinion. It may be a more valuable opinion than that of another man, but it is not final. It should be studied in connection with other lists, particularly those made by practical growers. If one desires to choose Varieties, therefore, he should consult the best growers of those plants in his immediate neighborhood; he should call upon the experiment station of his state or province; and he should consult the most recent writings on the subject.

VEGETABLE GARDEN. It is one of the choicest of pleasures to raise one's own vegetables. Make the Vegetable Garden ample, but economize labor.

Plant the things in rows, not in beds. Then they can be tilled easily, either by horse- or hand-tools. Wheel-hoes will accomplish most of the labor of tillage in a small garden. Have the rows long, to avoid waste of time in turning and to economize the land. One row can be devoted to one vegetable; or two or more vegetables of like requirements (as parsnips and salsify) may comprise a row. Have the permanent vegetables, as rhubarb and asparagus, at one side, where they will not interfere with the plowing or tilling. The annual vegetables should be grown on different parts of the area in succeeding years, thus practicing something like a rotation of crops. If radish or cabbage maggots or club-root become thoroughly established in the plantation, omit for a year or more the vegetables on which they live.

[Illustration: Lay-out of a farm Vegetable Garden]

Make the soil deep, mellow and rich before the seeds are sown. Time and labor will be saved. Rake the surface frequently to keep down weeds and to prevent the soil from baking (see _Tillage_). Radish seeds sown with celery or other slow-germinating seeds will come up quickly, breaking the crust and marking the rows. About the borders of the Vegetable Garden is a good place for flowers to be grown for the decoration of the house and to give to friends. Along one side of the area rows of bush fruits may be planted.

A home Vegetable Garden for a family of six would require, exclusive of potatoes, a space not over 100 by 150 feet. Beginning at one side of the garden and running the rows the short way (having each row 100 feet long) sowings may be made, as soon as the ground is in condition to work, of the following:

Fifty feet each of parsnips and salsify.

One hundred feet of onions, 25 feet of which may be potato or set onions, the balance black-seed for summer and fall use.

Fifty feet of early beets, 50 feet of lettuce, with which radish may be sown to break the soil and be harvested before the lettuce needs the room.

One hundred feet of early cabbage, the plants for which should be from a frame or purchased. Set the plants 18 inches to 2 feet apart.

One hundred feet of early cauliflower; culture same as for cabbage.

Four hundred and fifty feet of peas, sown as follows:

100 feet of extra early.

100 feet of intermediate.

100 feet of late.

100 feet of extra early, sown late.

50 feet of dwarf varieties.

If trellis or brush is to be avoided, frequent sowings of the dwarfs will maintain a supply.

After the soil has become warm and all danger of frost has passed, the tender vegetables may be planted, as follows:
