4. The burden which would rest upon a country to provide the 



necessary appropriation for the control of a nev/ly intro- 

 duced disease. 



5. The national loss which would result from the ravages of 



such disease among the valuable economic crops of the 



country. 

 If we would be able to approximately estimate the annuel cost 

 lor carrying on this kind of fruitless work together with the 

 losses from such disear-es, you must grant that the same would 

 reach an incredible figure. Remember for a moment the cost of 

 fighting imported pests like the Gipsy Moth, Brovmtail Hoth, 

 Potato Canker, Gooseberry I.Iildew, Phytophthora infestans and 

 scores of others - all this vast expenditure could have been 

 saved if the export of diseased vegetation affected by other in- 

 sect or fungous diseases would have been made an international 

 offense. IIo doubt there are many similar laws and agreements 

 in force among nations, unquestionably effecting a universal 

 blessing. 



The invaeion of countries by destructive diseases will take 

 effect more and more as all methods of rapid traffic and the 

 competition among- nations v;ould serve to spread disease. It is 

 obvious that the saving of the immense sums now spend in many 

 countries in their effort to protect important agricultural 

 and horticultural industries from the invasion of diseases, by 

 the univ^Tsal adoption of such measures prohibiting ar making e^ 

 makin g- it illegal under penalty to export diseased vegetation, 

 would result un greatly increased funds for the cr.rrying on of a 

 very efficient system of controlling and combating diseases ex-
