DISCUSSION OF RESULTS OF ANALYSES. 
The juices from berries grown in Washington and Oregon differ 
markedly in composition from those from fruit produced in Cali- 
fornia. There is also a very large variation in the composition 
of juices from fruit grown in the various parts of these States. This 
probably is due to the fact that in the northern section the berries 
are grown under heavy rainfall, whereas the land in California usually 
is irrigated. Apparently California juices have a somewhat higher 
ash content and a lower acid content than the juices from the more 
northern States. Observations extending over several seasons would, 
of course, be necessary to confirm this apparent difference. 
It would seem impossible to determine exactly the amount of 
added water present in Logan blackberry juice. Its presence can be 
detected, however, and the amount roughly approximated. Table 5 
gives the tentative limits suggested for the most significant determi- 
nations of Logan blackberry products. The nonsugar solids are cal- 
culated from the solids in vacuum.
