" E. D. W.," Independence, Iowa, asks: " Can you give me any information in regard to the most economical plan of heating and watering a forcing-house, 12x24, built mostly under ground?"

[For so small a house, a brick flue would be the most economical; the furnace at one end and the chimney at the other. Watering will depend on many circumstances. If there is a chance to let a flow of water through a pipe, watering may be done with a hose, and especially if the plants are vegetables or flowers like carnations or roses planted in benches. But if the plants are in pots, the ordinary watering pot had better be employed, because so many plants will need watering when others do not, and it is an injury to plants to give them water when they do not need it. - Ed. G. M].
