The grape-storage investigations of the Bureau of Plant Indus- 
try included a study of the possibility of substituting the native- 
grown grapes for at least a portion of the imported fruit. It 
will not be possible to entirely replace the Spanish fruit save by the 
successful production in commercial quantities of varieties as long 
keeping as those shipped from Spain. Thus far it has been found 
impossible to hold any commercial California varieties throughout 
the entire winter season. The successful storage of California table 
grapes depends, therefore, upon their adaptability for keeping in 
sound and marketable condition through the holiday season at least. 
EARLY GRAPE-STORAGE INVESTIGATIONS. 
When the work of the Bureau of Plant Industry was begun in 1906 
there were no established precedents to serve as guides, no systematic 
investigation of the behavior of California table grapes in storage 
having been made up to that time. It was necessary, therefore, to 
study the fundamental factors governing the behavior of the fruit, 
and the first efforts in the investigation were directed toward de- 
termining the nature of these factors. 
Perhaps the most important of these influences is the type of pack- 
age in which the fruit is shipped, and next in importance is the 
character of filler used. Practically all of the California grapes are
