In this experiment, cuttings appear to have received a positive 

 benefit from having been soaked in polassium sulj)hide solution. 

 Desiring to ascertain tbe effect of soaliing for a longer time and 

 in stronger solutions, a second experiment was made as follows: 



April 25, 1805, six lots of cuttings of tbe variety Uncle John 

 were selected at random from rust-infested stock. All poor cut- 

 tings were discarded. Five lots were soaked in strong solutions 

 of potassium sulphide, and one lot was left untreated for a check. 



The results are set forth in the following table: 



It will be seen that strong solutions of j)otassium sulphide 

 proved very injurious. Even of those soaj^ed for one hour in 

 strength 1 oz. to 1 gal. (1-134) less than 50 per cent, rooted, 

 whereas, in the previous exjieriment this strength for one-half 

 hour appeared to benefit the cuttings. 



These experiments on the soaking of cuttings are so incomplete 

 that we arc not warranted in drawing conclusions from them, 

 and. so f.ii ms I know, no other experiments of the kind have 

 Itccn icj)oi(<d. Ilowcvci-, it sc<'Tns 1(» nio not imjjrobable that 

 some treatment of this kind may yet be found advantageous. 



The experiments indicate that copper sulphate cannot be used 

 for this purfiose. Of cuttings soaked one-half hour in a 1-2000
