of the fungus is the best cure. Care should also be

 little boiling water and add five gallons of water ; 

 slake 602 of lime in some water, when it is cool pour 

 it into the solution of copper, and stir well together. 

 To test the mixture so as to be quite sure it will not 

 injure the foliage, hold the blade of a bright knife in 

 it for a minute ; if the blade is unchanged it is all

 Potassium. — Dissolve 102 of sulphide of potassium 

 (liver of sulphur) in a quart of hot water, and dilute

 and it is unfortunately very common, plants both in

 in a well-ventilated greenhouse they are not attacked. 

 When badly diseased, recovery is possible if the plants 

 are placed in the airy part of a greenhouse. Cut off 

 all diseased leaves, and in time the plants will throw 

 off the affection. This does not occur in the case 

 of rust. 



Bacteriosis. — Mr. Douglas writes : " This disease 

 seems to have been imported from America." Mr. 

 C. W. Ward in his book on the Carnation says : 

 "The disease shows readily upon leaves recently 

 attacked in the form of translucent dots in otherwise 

 healthy foliage. Later on the dots enlarge and run
