=In the greenhouse.=--Here pruning and training are essential. The plants may be supported by wires or strings (a coarse wool twine will answer), twisting the string about the plant as it grows. The growth is usually confined to a single shoot, though some growers allow two (Fig. 24); the method of pruning does not differ from that given for field culture, but it is more important that the plants be gone over often and the branches removed when small. If allowed to do so, branches would spring from the axil of each leaf and the plant would become a perfect thicket of slender branches and leaves and produce but little fruit. The main stem is sometimes pinched out after three or four clusters of fruit are set and the branch from the axil of the first leaf above is allowed to take its place. This tends to hasten the maturing of the fruit clusters already set. After several clusters have matured, or the main stem reaches the top of the house, some growers allow a shoot from the bottom to grow and as soon as fruit sets on it the first stem is cut away and this takes its place. Others prefer to remove the old plant entirely and set in young ones. A plant ready for transplanting is shown in Fig. 25. In figures 26, 27 and 28 are shown interior views of greenhouses at the New York station at Geneva, the Ohio station at Wooster, and the New Hampshire station at Durham. Note the strong, vigorous plants in Fig. 26; the method of utilizing tile for watering in Fig. 27; and the ground-floor bedding in Fig. 28. CHAPTER XIV Ripening, Gathering, Handling and Marketing the Fruit Tomatoes ripen and color from within outward and they will acquire full and often superior color, particularly about the stems, if, as soon as they have acquired full size and the ripening process has fairly commenced, they are picked and spread out in the sunshine. The point of ripeness when they can be safely picked is indicated by the surface color changing from a dark green to one of distinctly lighter shade with a very light tinge of pink. Fruit picked in this stage of maturity may be wrapped in paper and shipped 1,000 or 2,000 miles and when unwrapped after two or ten days' journey will be found to have acquired a beautiful color, often even more brilliant than that of a companion fruit left on the vine. Enclosing the fruit while on the vine and about half grown in paper bags has been recommended, and it often results in deeper and more even coloring and prevents injury from cracking, but the fruit so ripened, while more beautiful, is not so well flavored as that ripened in the sun. But Americans are said to taste with their eyes, so that in this country, fruit of this beautiful color will often out-sell that which is of better flavor though of duller color.
