BULBS AND THEIR CULTURE. 93 



in Fig. 28. This has an inner tube in which the roots 

 are eon fined. 



Of narcissus, the Paper White is the favorite with 

 the florists. It is very easily forced and comes at a time 

 when there is a scarcity of white flowers. The Early 

 Roman and Von Sion, Incomparable and Trumpet Major 

 daffodils are most largely grown of the other kinds. 



The tulips (Fig. 29) are highly esteemed for their 

 bright colors. They range in color from white and yel- 

 low to rose, scarlet and crimson. The single sorts are 

 generally used for forcing ; the Due Van Thol, being one 

 of the best early sorts, is about the only one that 

 can be brought into flower by Christmas. By the first 

 to the middle of January such kinds as La Heine and 

 White Pottebakker, white; La Belle Alliance, scarlet; 

 Brilliant, vermilion ; Yellow Prince and Chrysolora, yel- 

 low ; Eose Grisdelin and Cottage Maid, pink ; Keizer- 

 kroon and Joost van Vondel, striped, can be brought 

 into flower. Among the later sorts, Murillo, double 

 pink, and Tournesol, red and yellow, will be found 

 desirable varieties for forcing. As a rule, the solid col- 

 ors in tulips will be found preferable to the striped 

 varieties. By bringing in the Due Van Thol about the 

 last of November and giving it seventy degrees, it will 

 flower by Christmas. With this and other varieties 

 that show a tendency to have short stems, marked ben- 

 efits can be obtained if they are shaded with cheese 

 cloth or some similar covering. These varieties are 

 most esteemed for early winter and to follow them 

 there is a long list of named sorts in solid colors or vari- 

 egated. For other varieties of tulips and narcissus, the 

 leader is referred to any of the bulb catalogues, that are 

 Issued each year. 



The crocus is also largely grown for purposes of sale 

 or decoration. It requires the same care as tlie tulip, 

 but is generally used to fill pans, or to border pans of
