DAMPING OFF is a name applied by gardeners to the 

 premature decay of the stems of seedlings, and other 

 tender plants. It is caused by a fungus, Py'thium 

 debarya'num, owing to the soil and air in which they are 

 vegetating being kept too moist or damp. Flower 

 seedlings are especially liable to be thus affected ; and, 

 to prevent this, one third of the depth of the pot should 

 he filled with drainage, and the soil employed, instead of 

 being sifted, allowed to retain 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 moisture 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. The latter should be kept somewhat drier. In 

 bad cases the seedlings should be pricked off as soon as 

 they can be handled, into fresh soil. 



DA'NAE. (Danae, the Greek name of the Alexandrian 

 Laurel. Nat. ord. Liliaceae. Allied to Ruscus and 

 Asparagus.) 



A hardy, evergreen shrub, which thrives best in 

 sheltered situations amongst other shrubs or trees in 

 ordinary garden soil.

 loam. Summer temp., 60 to 90 ; winter, 48 to 55*.

DA PHNE. (So called after the fabled nymph of that 

 name. Nat. ord. Daphnads [Thymeleacea?]. Linn. 8- 

 Octandria, i-Monogynia.) 



Extreme causticity is the general property of the 



Daphnads the Spurge Laurel and Mezeremn particu- 

 larly so. Seed for most of the species, especially of the 

 D. Laure'ola, or Spurge Laurel ; used as a grafting stock 

 for most of the rarer and tender kinds. As the seed is 

 two years in vegetating, it is usual to keep it some time 

 in sand, in a heap. D. Cneo'rum and other dwarf kinds, 

 especially if at all trailing, are generally propagated by 

 layers in summer. A close pit for grafting the finer 

 kinds, in March or April, is an advantage. Most of 

 them like a good proportion of sandy peat ; but the de- 

 ciduous Meze'reum prefers pure loam. The odo'ra and 

 odo'ra ru'bra are nearly hardy in the climate of London ; 

 but farther north they require the cold pit or greenhouse.
