 spreads the disease. In addition, therefore, to 

 cutting off all infected leaves and burning them at

 all plants in the vicinity with some weak antiseptic 

 solution. Dilute carbolic acid, mixed according to 

 directions, is said to be a specific. 



Mr. Charles Blick, gardener to Martin R. Smith, 

 Esq., states that he had a whole house of "Mal- 

 maison " Carnations infected badly with this disease 

 in January, 1891, but that he ultimately got rid of 

 it by persistently sponging the plants Avith a weak 

 solution of Gishurst's compound. The plants 

 regained their wonted vigour and flowered well. 



The disease would appear to be one that can be 

 readily got under if discovered at an early stage, ^md 

 treated with patient and persistent attention. 



The other fungoid disease we have mentioned,
