However, if such lime wore used, it might be necessary to change 

 the lime before the end of the storage season. Therefore, the labor 

 involved in changing the lime, if this becomes necessary, compared to 

 the cost of fresh lime, should be considered when deciding whether or 

 not to use "old" lime. 



Another point worth noting about the data in Table 2 is the pattern 

 of absorption of CO2 by the lime in the scrubber. By November, the lime 

 at the surface (on the top) of the bag was essentially saturated with 

 CO2. The composite sample showed, however, that the inner contents of 

 the bag were not nearly saturated. But, the CO2 content of the inner 

 contents rose at a steady rate throughout the storage season, until in 

 March the inner and outer samples had almost identical CO2 contents. 

 It would appear, then, that at least in our experimental lime scrubber 

 penetration of the atmosphere through the entire contents of intact bags 

 of lime was readily occurring, and full utilization was being made of 

 the lime in the bag.

Pollination Studies on the Highbush Blueberry - Due to con- 

 cern among highbush blueberry growers in Michigan about inadequate pol- 

 lination, Joseph Dorr and E.G. Martin, Department of Entomology, Michi- 

 gan State University, East Lansing, Michigan, investigated this problem 

 and the results of their studies are reported in the quarterly Bulletin 

 of the Michigan Agricultural Experiment Station, Volume f+8 , No. 3, Feb- 

 ruary, 1965. Their studies indicate that: 



1.. The bee population working many Michigan highbush blueberry 



plantings is inadequate for optimum pollination. Lack of ade- 

 quate pollination reduced yield and fruit size, and delayed 

 maturation of the berries. 



2-. Honeybees are capable of pollinating highbush blueberries. 



3. Honeybees appear to have varietal preferences. They were ob- 

 served to fly over Earliblue to work other varieties and did 

 not work Coville well. 



fj-. The honeybees were most numerous on the bushes close to the 

 hives. Therefore, it was suggested that an even distribution 

 of beehives throughout the planting should result in the most 

 complete pollination.
