The bottom of the frame is placed a littlebelow ground and a pit is dug about 18 inches deep. This is filled with fresh horse manure,on top of which is placed 6 inches of rich garden The glass sash on top slopes toward thesouth to catch the sun. as tomatoes, peppers and eggplant may stand a temperature ofeighty to ninety degrees. Ventilation is accomplished by raising the sash at the north end 84 HOTBEDS, COLDFRAMES, AND FLOWER PITS and supporting it with two sticks at the corners of the sash. Whenthe weather becomes very warm, the sash may be removed en-tirely during the day. Ventilation not only controls the temperature of the bed butalso supplies the necessary fresh air and helps keep surplus watervapor from accumulating inside. Too much heat and too muchwater vapor is certain to cause damage to the plants. Damping-off fungus is a common trouble in hotbeds and poor ventilation isapt to help start it. Watering.—As the plants are growing under the cover, water-. Fig. 58.—A three-sash hotbed ready for use. (Kentucky Station). ing is a matter which must be given close attention. If too muchwater is applied, the soil will become soggy and the plants will turnyellow and suffer for want of air in the soil. If the bed is properlyventilated, considerable watering is necessary because the heat ofthe bed will diy out the soil. If the bed is filled with water, themanure underneath may stop heating. Light applications of waternearly every day is the best plan with the hotbed. The Hotbed Becomes a Coldframe.—After some weeks themanure in the hotbed will fail to give out heat because the rottingis advanced so much. In this condition it may be considered merelya coldframe as it gets its heat only from the sun through the glass. FRAMES FOR BE
