WORMWOOD 



XANTHORRHCEA 



these are only too well known to gardeners and golf-green 

 keepers under the name of worm-casts. This digested 

 soil is very fertile and feeds the grass, but is objectionable 

 to those using the grass. A weak solution of carbonate 

 of ammonia in water will soon bring the worms to the 

 surface. Water, saturated with lime by steeping a 

 quantity of quicklime in it for twenty-four hours, and 

 then watering the grass with the clear liquid, acts in a 

 similar way. Both these remedies may be used in 

 flower-pots to drive out or kill the worms that may be 

 in them. Worms are really harmful in pots by stopping 

 up the drainage with their casts, and making the soil 

 water-logged. Their burrows in lawns act as natural 

 drainage.
