enoufjh variation to account for the groat differences in taste found in commer- 

 cialiy sliipped fruit. LaclJ of ventilation during ripening increased tiie acid 

 content approximately 138 per cent over that of vine-ripened fruit. Wrapping 

 the tomatoes also greatly increased the acidity. 



The author concludes that wrapping probably modifies the course of ripen- 

 ing to such an extent as to account for marked changes in taste and flavor. 

 The combined results of picking fruit green, of wrapping, and of closing the cars 

 in transit probably account for the total differences existing in quality between 

 conmiercially shipped and vine-ripened tomatoes. 



Selecting and saving tomato seed, W. A. Huelson {Indiana Sta. Bui. 250 

 {1920), pp. 26, figs. 13). — This bulletin outlines a method of selection that can 

 be used by the grower or the canner, and gives definite information as to the 

 characteristics of plant and fruit most desirable for different purposes. A 

 method of saving, cleaning, and drying tomato seed worked out by the station 

 in cooperation with the Indiana Canners' Association is described in detail, 

 and illustrations are given of the machinery required for the work. Data are 

 also given showing variations in yield between strains of the same varieties of 

 tomatoes secured from seedsmen in different parts of the country. A short 

 bibliography of literature dealing with strain tests and breeding work with 

 tomatoes is appended.
