 round the Kanunculus bed, their roots 

 tempt the wire worm from those of the 

 choicer flower.

DAMPING OFF is a name applied by 

 gardeners to an ulceration of the stems 

 of seedlings, and other tender plants. 

 This ulceration arises from the soil and 

 air in which they are vegetating being 

 kept too moist or damp. Flower seed- 

 lings are especially liable to be thus 

 affected ; and, to prevent this, one third 

 of the depth of the pot should be filled 

 with drainage, and the soil employed, 

 instead of being sifted, allowed to re- 

 tain all moderately sized stones. The 

 seeds should be sown very thinly, 

 pressed down, and a little white sand 

 be sprinkled over the surface, because 

 this is not easily disturbed by watering, 

 and is not a medium that retains mois- 

 ture to the neck of the seedlings, where 

 dampness most affects them. A pot of 

 sand should be kept hot, and whenever 

 symptoms of the disease appear, a little 

 whilst hot sprinkled on the soil.
