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

4, The process is more or less deyitalizing 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 Kniffin plan, since 
with the former more wood can be left to support the vine than is 
possible with the latter system.
