Timely Hints for Farmers. ^ 



almost certain in time, if unchecked, to cause the death of the 

 tree. As this disease only affects the tree at the point where the 

 gall develops and in the adjacent tissue, if the gall be removed 

 and something be applied to the wound to prevent additional 

 growth, it can be held in check, and a minimum amount of harm 

 will come to the tree from its action* 



From a number of experiments carried on in the greenhouse, 

 where a large number of seedlings have been under observation 

 for the past two years, it has been shown that bluestone is of 

 marked value in treating the disease. In the field the following 

 has proved to be the most successful of any treatment as yet known. 

 The remedy should be applied in October and November or in 

 March and April, as at these periods of the year the growth of 

 the gall is the most rapid : 



Two parts of bluestone; 

 One part of copperas; 

 Three parts of quicklime. 



Crush the bluestone and copperas to a fine powder, thor- 

 oughly mix with the lime, and add enough water to make a thick 

 paste. In treating the disease the crown of the trees should be 

 exposed, all the galls cut away, and a quantity of the paste plas- 

 tered over the wounds. This remedy prevents the growth of the 

 soft, spongy tissue infested by the plasmodia. It is very import- 

 ant that all galls cut from the trees be gathered and burned.
