Perhaps the most desirable advance was made when the core 

 became broken and the seed-cavities were not all arranged around 

 or along a common center. The reader may be rewarded in a 

 search for the slices in which there is no distinct core, but, instead, 

 one or more locules in the center of the fruit. Once this im- 

 portant end was reached in the development of the tomato, the 

 way became clear for the development of fruits in which the core, 

 as such, does not exist and flesh and locules are interspersed as 

 shown in the slices at the right hand of the Plate. The reader 

 must not conclude that any one fruit is the type of all the others 

 upon the same plant. This may be true for the old-time and 

 simple types but the highly developed modern kinds will require 

 much further attention before that desired end is reached. 



A Preliminary Classification for Tomatoes. 



There are certain characters among tomatoes that are not 

 easily disturbed in the breeding of widely different sorts, and 

 from their behavior may be considered Mendelian. Thus, as 

 regards the whole plant, there are two types, namely, the "stan- 

 dard" and the "dwarf" and when these two are united the off- 

 spring in the first generation after the blend show one-quarter 

 of the dwarf type. Again, should a fine-leaved and a coarse- 

 ( "potato") -leaved variety be bred together the result is a quarter 

 of the coarse-leaved plants following immediately upon the blend 

 generation. In one set of crosses (the "Dwarf Champion" upon 

 "Magnus") where the two characters above considered are in- 

 volved the following results were obtained : 



Standard, fine-leaved plants, 49; theoretical, 45. 



" coarse-leaved " 16; " 15. 



Dwarf, fine-leaved " 13; " 15. 



" coarse-leaved " 7; " 5. 



In this instance, the "Champion" was "fine-leaved" and "dwarf," 

 that is, of the two unit characters (una) in question one was 

 dominant, namely, the foliage type and the other, the size of the 

 plant, was recessive, that is, excluded when its antagonistic char-
