Do varieties of tomatoes run outf (pp. 171-173). — " Studies of tliis 

 question were made in 1891 by gro\viii<? the same varieties from many 

 seedsmen. * * * In order to determine how long a variety may per- 

 sist we selected Grant and Canada Victor, which are old varieties; and 

 to find out how soon a variety may depart from its t\i)e we grcAv the 

 Ignotum." The results, as stated, co]itirm the previously expressed 

 views of the author, that varieties of tomatoes lose their distinguisliing 

 characters. In the case of seeds of Ignotum from fifteen dift'erent 

 dealers, 8 sami)les gave small and i)Oor fruits, which could not be recog- 

 nized as belonging to that variety. "It is not certain that all this vari- 

 ation is chargeable to running out of the variety." 



Impressions of varieties (pp. 173-176). — Brief descriptive notes are 

 given on 17 varieties. Ignotum is especially commended. Among 

 new varieties the following are the most promising: Cumberland Ked, 

 Long Keeper, Mitchell, Potomac, Red Mikado, and Stone.

 been recorded in Bnlletins Nos. 10, 21, and 28 of the station (see Exper- 

 iment Station Bi'(or(l,vol. i, p. 270; vol. ii, i». MCt; and vol. in. p. 91).

 tins Nos. 19 and 31 af the Michigan College and Station (permanently 

 bound in the Reports of the Michigan State Board of Agriculture for 

 18.S(; and 1887). 



The classification of varieties adopted by tlie author is as follows:

If the Cherry tomato is taken as the starting point of the cultivated tomatoes, the 

 evolution may be expressed as follows: 



I Pear-shaped sorts. — Oblong sorts. 

 Orangelield or similar kinds. — Angular sorts. 

 Green Gage, Large Yellow, White Apple, 

 «^uti i:> •. etc.* — Yellow ap])l«'-shaped sorts. 



Little Gem, The Cook's Favorite, or similar 

 kinds. — Large red sorts. — Grandifoliuin. 

 Validnm. 



There is much direct evidence to sup)»ort this genesis of the tomato. The most 

 donlttful point is whether the pear tomato has come from the cherry or is aboriginal 

 with it. For a discussion of the reasons for this tabulation, drawn from morphologv . 

 see an illustrated article in the American Naluralisl, June, 1887, p. 573.
