Mignonette. 195 



No remedy has yet been found that will entirely 

 cure this disease when once it takes possession. Air 

 slacked lime is used by some as a preventive, both 

 plants and soil being dusted with it. Mr. Richard 

 Donovan, a successful grower of the violet near Chicago, 

 recommends the use of the ammonia solution in the 

 following proportions : Three oz. of the carbonate of 

 copper dissolved in one qt. of ammonia. Use one gill 

 to three gallons of water, and apply to the foliage by 

 means of a syringe once a week. This will not eradi- 

 cate the disease, but if applied as soon as any indica- 

 tions of it are seen, it will do much towards holding it 

 in check. 



Were it not for these diseases, the flowers would be 

 so abundant there would be no market for them. As it 

 is, a scarcity is caused, and he who succeeds is reason- 

 ably sure of being able to dispose of his crop to advan- 

 tage.

For winter cutting, the first care is to obtain good 

 seed. The giant varieties used for this purpose are 

 not always reliable, and it is a much safer way for each 

 grower to raise his own seed, after once obtaining a 

 strain suited to his trade.
