3. That some varieties suffer a loss of quality when ringed there 

 is little doubt; other varieties do not appear to be affected in this 

 manner by the operation. Cutting back the new growth on ringed 

 arms appeared to result in giving better quality to the fruit. 



4. The process is more or less devitalizing in its effect on the 

 vine, depending in part at least, on the factors mentioned in the 

 second paragraph. It has been found in practice, however, that 

 some varieties when judiciously managed may be ringed for a 

 number of years in succession with little injury to the vine. 



5. Vines grown on the renewal system would seem to be better 

 adapted to ringing than these grown on the Kniffiri plan, since 

 with the former more wood can be left to support the vine than is 

 possible with the latter system.
