SPORTING is the term whereby gardener? 

 describe any deviation from the usual 

 form or colours of a plant or flower. 



SPOT, a disease occurring on the leaves 

 of the pelargonium, is a dry gangrene, 

 occasioned by an irregularity in the 

 supply of moisture and vicissitudes of 

 temperature, but especially if one of the 

 extremes is much below the degree of 

 heat most favourable to the healthy 

 growth of that plant. The reason of 

 this is very obvious. If a pelargonium, 

 or any other plant, be placed in a highly 

 stimulating heat, and is abundantly sup- 

 plied witb root moisture, it immediately 

 increases its surface of leaf to elaborate 

 and digest the large amount of sap for- 

 warded from tbe roots. If this amount 

 of sap is subsequently suddenly reduced, 

 by lowering the temperature and adding 

 water to the soil less freely, the increased 

 surface of leaf is no longer required, and 

 it is a law pervading all the vegetable 

 creation that the moment any one of the 

 parts of a plant is unnecessary to it, 

 immediately that part begins to decay.
