2. Draw off the winter floivage early in April as a rule, but every 

 third or fourth year hold it until after the middle oj May. 



3. On some bogs 7i)hich are level enough to permit it and on which 

 the vining is heaiy, the practice of holding the water up anwng the 7fnes, 

 but not covering them, for a week or ten days in late func^oould probably 

 be effeclii'e. 



B. On winter flowed bogs which have not water supply for 

 more than one reflowage or which cannot be reflowed rapidly 

 enough to prevent injury from frost : — 



1 . Put on the winter flowage as soon as possible after the cranberry 

 foliage has ripened and hardened. 



2. Hold this floioage every spring until the 20th oJ Apr if and every 

 third or fourth year until after the middle oJ May. It is the custom 

 with many growers to draw off the winter flowage late in March or 

 early in April. The more advanced in development the buds of any 

 plant are, the more likely are they to be destroyed by spring frosts. 

 By holding the water until the 20th of April the buds would proba- 

 bly be held back sufficiently to prevent much loss by frost in most 

 cases, while they would not be retarded enough to seriously affect 

 the blossoming or fruiting of the vines. While this practice of hold- 

 ing the water oil the bog would thus tend to help in the frost prob- 

 lem, it would also tend to reduce the fruit worm injury, as it is evi- 

 dent that the longer the water covers the bog the greater is the num- 

 ber of worms destroyed. 



3. In the case of bogs tvhich have water supply enough for abundant 

 reflowage but which it takes several days to cover, put the water on for 

 ten days or two weeks immediately after picking. Then draw this 

 flowage off and allow the foliage to ripen and turn before flooding 

 for the winter. 



C. On bogs which are dry or have scanty winter flowage : — 



Here only insecticides seem to offer much chance for success. An arsen- 

 ate of lead spray alone would probably never be at all effective on 

 account of its poor adhesion to the small fruit. The use of adhesives 

 with this poison promises well, but needs more extensive trial. It is 

 essential, if any insecticide be used against the fruit worm, that it be 

 applied before the worm has hatched from the egg, so that the first 

 meal eaten shall be a poisoned one, and that it be of such a nature
