Flax is still a frequent crop in the hilly districts, and sugar-beets are raised over large areas.
From a factory receive the beets, extract the juice and force it through pipes to the factory.
Hardier sorts of vegetable seeds and plants, such as beets, cabbage, cauliflower, celery, lettuce, onions, parsley, parsnips, peas, potatoes, radishes, spinach, turnip, &c., should all be sown or planted by the middle of the month if the soil is dry and warm, and in all cases, where practicable, before the end of the month.
The cereal crops (wheat, barley, oats, rye, maize); the cruciferous crops (turnips, cabbage, kale, rape, mustard); the solanaceous crops (potatoes); the chenopodiaceous crops (mangels, sugar-beets), and other non-leguminous crops have, so far as is known, no such power, and are therefore more or less benefited by the direct application of nitrogenous manures.
Sugar beets were first grown by irrigation in Utah; under that system it becomes possible to estimate closely the tonnage of the product.
