[Illustration: The Great B. B. (Brinton's Best) Tomato, Best for Main Crop.] The out-of-doors season is profitably prolonged by picking all the mature or nearly mature fruit when the first frost comes, in October, and placing these unripe tomatoes on straw in a cold frame. Covered with straw and with the sash to keep out frost, the fruit ripens in a satisfactory manner for several weeks. Such a frame must be well ventilated or the tomatoes will rot rather than ripen. [Illustration: New Fortune, one of the Best Second Early Tomatoes.] =Diseases and Enemies.=--Tomato diseases, fortunately, are not numerous. Blight sometimes sweeps off a whole field of early-set tomato plants, on farms where later plantings are quite healthy. This favors the theory that blight results from weakness caused by early planting in cold ground. It is a fungous disease, and may sometimes be prevented by the use of Bordeaux mixture. The same remedy is the best known preventive of black rot. Potato bugs may be either hand-picked or poisoned with Paris green. The tobacco worm sometimes causes much damage to the tomato. All diseased or blighted tomato vines should be promptly burned, and the crop carried to new soil the following year. =Marketing, Profits, etc.=--As already stated, choice tomatoes in clean baskets are always in demand, and a new basket will usually pay for itself on a single sale. The sum of $150 per acre may be quoted as the average gross receipts from tomatoes at present prices. This estimate is based on the low yield of a half-peck of fruit to each vine at 25 cents per basket. If sold retail, the tomatoes would command more money, while if sold in bulk to a canning factory the gross receipts might be larger or smaller, depending on the size of the general crop and other circumstances. TURNIPS AND RUTA BAGAS. Turnips and ruta bagas are closely related. The latter are turnips in fact, and are frequently called Swedes. The common method on many farms is to sow turnips broadcast, but it is a far better practice to sow both these and the ruta bagas in drills, so that they can be kept clear of weeds and worked by horse-power. Not only are these advantages secured, but the row system makes it possible to take out the superfluous plants, and secure roots of uniform size and shape. Turnips and ruta bagas have high economic value as foods, both for humanity and for live stock. =Turnips.=--Turnips are grown for market purposes both in spring and in fall. In the spring the seed should be sown early, in mellow soil. For the fall crop the seed may be sown either in July or August. The rows in garden or field may be as close as can be conveniently worked. TURNIP.--For earliest, we recommend Purple Top and White Milan. For fall crop, Mammoth Purple Top Globe and Golden Ball.
