A. FLAT BED IN A BARN Two t>-pes of beds are in general use, the flat bed and the ridge bed, as shown in the illustrations. Both have their advantages, and disadvantages. If the additional item of labor is not too great, the ridge bed is probably the best. The cone-shaped ridge has a width of IS to 22 inches at the base and an equal height. The smaller ridge is used in wann houses and the larger in cold houses. The ridge bed is more easily INST.\LLATION OF BEDS Mushroom beds are of two general types, (1) the flat bed, frequently re- ferred to as the Enghsh, and (2) the ridge bed, known as the French tj'pe. In making the former the entire floor space may be utilized as a bed, and the beds may be arranged in the form of tiers or shelves, as shown in the figure. In low cellars or caves, and, indeed, wherever the amount of floor space is not the most important , it would be well to avoid the use of shelves; but where the amount of floor space is an important factor they may be adopted to advantage, although the additional labor involved in the grow- ing of a crop under such conditions is an item to be considered. When the shelves are used one should be careful to whitewash these after each crop, in order to avoid the increased danger from insect depredations. In any case, flat beds should be made from eight to ten inches deep. Ridge beds enable one to get a somewhat greater surface space in a given area, but they are also more expensive, so far as the labor of construction is. Please note that these images ar
