near the surface exposed to light, sprouts are sure to arise. The power of vegeta- 

 tive propagation is possessed by all currants and gooseberries, but the swamp 

 forms are notorious in this respect. The skunk currant, the swamp red currant 

 and the swamp black currant reproduce in this way much more regularly than 

 by means of seeds. 



The difficulty of uprooting is greatly enhanced where the plants grow 

 among dense young maple seedlings or brambles. In such cases the whole ground 

 cover must be completely uprooted and destroyed in order to make sure of the 

 currants. 



Finally, the difficulty and expense of eradication increases the larger the 

 number of plants that must be handled. The survey reveals astonishingly 

 large numbers in many places. This consideration alone would make it doubt- 

 ful whether any large-scale eradication enterprise could be undertaken success- 

 fully except at a prohibitive expenditure. When all the factors are taken into 

 consideration this conclusion would seem to be amply confirmed. 



I have the honour to be. Sir, 



Your obedient servant.
