Forcing of Rhubarb. —The forcing of Rhubarb has now become quite a profitable industry in the vicinity of many of the large cities. It may be forced either in the field where the roots are growing or lifteil and placed in hotbp< green- house l)cn(.'hes or in a dark cellar. See Fig. 2113. Much the larger part of the Rhubarb which is offered for sale dur- ing the winter months is grown in rough forc- ing houses which are built over the plants in the field. Fig. 2114. These hoiises are sim- ply and cheaply con- structed, the sides usu- ally being about five feet high, of rough boards, which are covered with cheap building paper. The roof is formed of hotbed sash. These buildings are usually from 24 to 36 feet in width and of any desired length. Artificial heat is generally provided, steam being the most popular, although the sun is at times depended upon to give the required heat. The soil moisture is usually suffi- cient, so that no water is given. Plants for forcing should be set not more than two by three feet apart and should be fertilized annually with liberal dressings of compost, that made from cow and hog manure being considered the best. The sash should be placed upon the house during the first part of February, and may be removed for use on hotbeds and coldframes in from four to six weeks. Th
