EXPERIMENT STATION. 



[Jan. 



would pass through a very fine sieve, and this fine powder used 

 for the other work. The " insoluble matter " was determined 

 by digesting 1 gram with about 200 cubic centimeters distilled 

 water at room temperature, filtering through a tared filter paper 

 and drying. The filtrate was titrated with n/5 alkali, using 

 l^henolphthalein as an indicator, and calculated as malic acid. 

 For crude fiber the methods of the Association of Official Agri- 

 cultural Chemists were followed, except that the sample was 

 not previously extracted with ether. 



The results of this work are shown in Table 5. Erom this 

 table it appears that there is slight variation in the water con- 

 tent of these apples, those from Arkansas and Oklahoma having 

 a little lower water content that those from the north. There 

 is nothing in this column to account for the observed differences 

 in juiciness and quality.
