=Starting plants.=--From about the latitude of New York city southward, it is possible to secure large yields from plants grown from seed sown in place in the field, and one often sees volunteer plants which have sprung up as weeds carrying as much or more fruit than most carefully grown transplanted ones beside them. In many sections tomatoes are grown in large areas for canning factories, and as a farm rather than a market garden crop, individual farmers planting from 10 to 100 acres; and to start and transplant to the field the 25,000 to 30,000 plants necessary for a ten-acre field seems a great undertaking. Tomato plants, however, when young, are of rather weak and tender growth, and need more careful culture than can be readily given in the open field; and, again, the demand of the market, even at the canning factories, is for delivery of the crop earlier than it can be produced by sowing the seed in the field. For these reasons it is almost the universal custom of successful growers to use plants started under glass or in seed-beds where conditions of heat and moisture can be somewhat under control. I believe, however, that the failure to secure a maximum yield is more often due to defective methods of starting, handling and setting the plants than to any other single cause. In sections where tomatoes are largely grown there are usually men who make a business of starting plants and offering them for sale at prices running from $1 or even as low as 40 cents, up to $8 and $10 a 1,000, according to their age and the way they are grown; but generally, it will be found more advantageous for the planter to start his plants on or near the field where they are to be grown. =Tomato plants from cuttings= may be easily grown, but such plants, when planted in the open ground, do not yield as much fruit as seedlings nor is this apt to be of so good quality; so that, in practice, seedlings only are used for outside crops. Under glass, plants from cuttings do relatively better and some growers prefer them, as they commence to fruit earlier and do not make so rank a growth. Seedlings can be most easily started and grown, at least up to the time of pricking out, in light, well-ventilated greenhouses, and many large growers have them for this specific purpose. Houses for starting tomato plants should be so situated as to be fully exposed to the sun and not shaded in any way; be provided with heating apparatus by which a night temperature of 60 and up to one of 80 deg. F. in the day can be maintained even in the coldest weather and darkest days likely to occur for 60 to 90 days before the plants can be safely set out in the open field; and the houses should be well glazed and ventilated.
