Narcissi may be forced into flower through the winter, as described on p. 345. A popular kind for winter bloom is the so-called Chinese sacred lily. This grows in water without any soil whatever. Secure a bowl or glass dish, about three times the size of the bulb; put some pretty stones in the bottom; set in the bulb and build up around it with stones so as to hold it stiff when the leaves have grown; tuck two or three small pieces of charcoal among the stones to keep the water sweet, then fill up the dish with water and add a little every few days, as it evaporates. Set the dish in a warm, light place. In about six weeks the fragrant, fine white flowers will fill the room with perfume. The Paper-white, closely allied to this, is also forced, and is one of the few good bulbs that may be bloomed before Christmas. The Van Sions, single and double (a form of daffodil), are also much forced.
