Legislation 



smaller dressings calculated to avoid its necessity 

 (see Chapter II.)- 



An opposite state of affairs encourages a few 

 bacterial diseases such as iris rhizome rot, and here 

 the admixture of superphosphate of lime at the rate 

 of 1^-2 oz. to the square yard will be beneficial. 



13. Of recent years legislation has been aimed 

 at the control of certain plant diseases, but while of 

 some value when carefully considered and efficiently 

 and intelligently administered, too much must not 

 be hoped from it. Legal enactments regarding 

 plant diseases are apt to leave too many loopholes 

 through which the fungus may escape and spread 

 for any great dependence to be placed upon it. 

 Nothing short of cessation of all commerce and 

 intercommimication is likely to stop the wide- 

 spreading of disease, and even that would fail to 

 stop its spread over narrower areas. Loyal observ- 

 ance of the enactments, together with personal 

 observation, intelligent cultivation, and prompt 

 application of remedial measures, are all requisite. 



14. We close this chapter with a reiteration of 

 the advice to maintain good health by attention to 

 hygienic requirements, i.e. good treatment. Avoid 

 damp, close quarters; avoid draughts; avoid 

 acidity of soil ; avoid over-manuring.
