DUTCH BULBS. 185 



" it is too much trouble ; " so, after flowering, they are usu- 

 ally thrown away or rapidly dried, and in the spring set out 

 in the flower garden, where they produce weak bloom for 

 years. If small bits of powdered charcoal be mixed with 

 the earth, it imparts great depth and brilliancy of color 

 to the flowers, and a dark, rich green to the foliage. Bone 

 shavings or horn scrapings assist a full development of 

 foliage and flower. If the plants are watered once a fort- 

 night with a very weak solution of glue, or a few drops of 

 hartshorn added to the water, the same effect will be 

 produced. 



IN SAND. 



The bulbs may be grown in pure sand. Silver sand is 

 the best, but common house sand mil do if well washed, 

 to free it from salt. 



Plant and treat as directed above. The bulbs should, 

 however, be transplanted to earth after blooming, and dried 

 off gradually. A pretty effect is produced by covering the 

 sand with moss. 



IN Moss.
