parent ('Trincess") was the three-quarter blood. Had a larger num- 

 ber of plants been employed for each secondar}- cross, it is likely that 

 the yellow plants would have l>eon found in them all. This assumption 

 is based iipon the fact that there was no apparent blending of the 

 yellow and green qualities, and the former is a unit character that 

 follows the Mendelian law. Slice-view of a fruit is shown at 9, in

The "Stone-South Jersey" Family. 



The "Stone" is one of the most popular of the later varieties of 

 tomatoes — in fact, it is one of Livingston's test in his long list of 

 excellent sorts. It is a standard, fine-leaved, red -fruited, productive 

 variety, medium in size and season, that was exceeded by but few in 

 the score made in 1904. The fruit is solid, with a thick wall, ripens 

 evenly and carries well. The "South Jersey" is a leading red sort 

 among the early group tecause of its quick growth and large fruits. 

 The latter are, however, very irregular and in striking contrast with 

 the smoothness and uniform size of the "Stone." The first cross — 

 that is, the "Stone" upon the "South Jersey" (123 x 119)— gave large 

 plants, and, as expected, the foliage was of the ordinary sort, like both 

 parents. The fruits were very large and quite irregular, but much 

 superior to the "South Jersey" in this respect. The cross of the male 

 parent upon the first cross 122 (122x119) gave large plants, with 

 medium fruits that were comparatively smooth, but there was a lack 

 of productiveness. The reciprocal of this (123x119) 123 produced 

 very large and productive plants, with large fruits, that were irregular. 

 The field note-book records that this cross might be good for canneries. 

 There seems to be some difference between the reciprocals in this 

 case of inbreeding, ^^^len the "South Jersey" is bred to the cross 

 119 (123x119) more earliness is obtained than in the last-named 

 union of the same varieties, in other words, where there is three- 

 quarters of the "South Jersey" blood. The fruits here were, many, 

 quite flat and cracked somewhat. The reciprocal of this, namely 

 (123 X 119) 119, gave less objectionable fruits than the last and were 

 a decided improvement upon the "South Jersey." There may be some 

 loss in speed, but that remains to be determined. *
