protect her interests from within and without. It seerns a sur- 

 prisingly ludicrous policy - within each country war is waged 

 against diseases - but countries willing to spend millions to 

 control diseases within its ovm horders. distributes the very 

 same disease all over the world without the slightest hesitation 

 or concern. 



Hot until V7e are able to devise practical means to prevent the 

 continuance of this practice and, what is more, have these recom- 

 mendations universally adopted, will the problem of fighting diseases 

 be successfully solved. Certainly the prohibition of the importation 

 of all kinds of vegetation affected by diseases is guite useless. 



In conclusion of my address let me consider the more important 

 features of such a measure. It is at once apparent that it would 

 be of no use trying to carry out this or any other similar scheme 

 in practice without an international agreement and international 

 effort. In order to carry into effect this plan, careful con- 

 sideration should be given and all objections be carefully discussed 

 to meet the special requirements. let us consider that such a 

 measure v/ould be found practicable, what are the necessary steps 

 to take to render thisscheme possible of execution: For this reason 

 let me call to ycur mind 



1. The large expenditure necessary to maintain a service of 



inspection, and all incidentals connected with such work, 

 at the port or ports of entry. 

 E. The considerable cort of compensation for any destroyed 



vegetation found diseased on importation. 

 S. notwithstanding inspection and compensation, the very 



dubious efficiency of such measures when dealing \rith 

 fungous and bacterial diseases.
