THE MONTHLY BULLETIN. 51 



"Any measures preventing the plant from developing leaves will be 

 effective. The following have been thoroughly tried: cut the thistles 

 down close to the ground -if a large patch, use a scythe — then dose the 

 ground well with a solution of arsenic, carbolic acid or other poison 

 The wash from sheep dips will do, or even a liberal dressing of common 

 salt. Repeat the treatment if possible as soon as the plants show above 

 ground ; never allow them to develop leaves. Remember that the leaves 

 are the lungs of the plant, and without them it must die. Even old 

 established plants will, by this treatment, be eradicated in two years, 

 ami proper vigilance will prevent the pest ever again obtaining a 

 foothold. 



"The expense and trouble will be more than repaid by the result, 

 i.e., extermination, and that will be more cheaply and more easily 

 effected now than some years hence. The Canada thistle never dies out. 

 Slowly but surely its roots penetrate in all directions, and if the farmer 

 does Q01 eradicate the thistle, the thistle will eradicate the farmer."
