 L. Canadense, L. Philadelphicum, L. Catesbai, L. Caro-

 ingtonianum, L. Humboldtii, L. parvum, L. Calif ornicum, 

 L. pardalinum, L. Roezlii, L. Parryi, and L. Walkerii, 

 from California. It may be added here that the California 

 Lilies often remain in the ground a whole year before 

 growing. 



FORCING. 



All the varieties succeed well grown in pots ; but 

 two, L. candidum and L. longiflorum, bear what is 

 termed forcing, or are made to bloom out of their natural 

 season. The L. speciosum class and L. auratum do not force 

 well. L. candidum, or the white panicled Easter Lily, 

 is the species so extensively forced for flowers for Easter. 

 The method is to plant the bulbs in six-inch pots, deep 

 enough to merely cover the bulb, any time from Sep- 

 tember ist to December ist, plunging the pots of those 

 potted early to the rims out of doors in a sheltered, 

 warm spot, and covering up with leaves as col^ weather 

 approaches, so that they shall not get frozen at any time. 

 Those that are potted later, say from the middle of 

 November, should be plunged in the same way either in 

 the soil under the benches in a cold green-house or in a 

 cold frame. The object is in all cases to get them to 

 fill the pot with roots in a low temperature. When the 

 pots are well filled with roots, they may be brought into 

 a higher temperature, say 55 at night and 10 or 15 

 higher in the daytime. If the pots are well filled with 

 roots they will come into flower from eight to ten weeks 

 after being placed in the above temperature. When the 

 flower stems begin to ascend, the plants may be liberally 

 supplied with liquid manure (made from one bushel of
