THE SPIRIT OF THE SOIL 



seems to open up the soil and to let the grass through, 

 after which this slight sponginess disappears. Not only 

 have these dressings had a most remarkable effect on the 

 blades of the grasses, but root growth has also been 

 increased to a very considerable extent."

Auricula 



Mixed in soil 



I find that auriculas 

 potted with humogen 

 are quite free from 

 woolly aphis, and those 

 not so potted are still 

 showing same. 



A friend I gave some to 

 finds the growth bet- 

 ter, and confirms what 

 I say with regard to 

 aphis.
