 strenght, leaving them in this for five or ten minutes, then plant- 

 ing them immediately, while still wet with the Bordeaux. This 

 treatment was especially effective in cleaning up roots which alrea- 

 dy showed the rust. The rust sloughed off, and the roots came 

 out next year in a fine white condition. The treatment has not as 

 yet been thoroughly tested in this country, but it seems it would 

 be worth while for our growers to try it. Great care should be 

 exercised in preparing the Bordeaux for this treatment, for an 

 excess amount of copper sulphate would result in killing the 

 roots. — Author.]
