16 BULLETIN 1015, U. S. DEPARTMENT OF AGRICULTURE. 



Fruit medium large, oblate, bright red, with occasional shallow cracks either 

 encircling or radiating from the stem; stem-end cavity shallow,' smooth; 

 blossom-end basin small ; stylar scar small, circular ; skin thin ; vertical section 

 medium long, oval ; cross section round, smooth ; walls thick, firm, juicy, evenly 

 colored ; cells many, small, irregular, well filled ; seeds fairly numerous, small ; 

 pulp medium thick; core not defined; flavor sprightly acid. 



The Arlington 8 and Columbia varieties are selections from the 

 Greater Baltimore. As they are similar in fruit characters, the 

 illustration for the Arlington (PI. IX, fig. 2) will serve for both) 

 varieties. 



Like their parent variety, the Arlington and Columbia produce a. 

 heavy crop of large, smooth, deep-red fruit, which ripens uniformly ; 

 in fact, it is practically free from green tissue around the stem by 

 the time the blossom end is ripe, but it ripens so fast that it can not 

 be held long. Although they are similar in many respects, the 

 Arlington produces a little larger vine than the Columbia and seems 

 to possess a little more resistance to wilt. There is very little dif- 

 ference, however, in their yield. 



They are medium-late tomatoes of the canning type and should 

 be tried wherever the Greater Baltimore is used, as they are adapted 

 to the same environmental conditions and produce the same quality 

 of canned fruit. 



Variety very productive, late, highly resistant to tomato wilt (Fusarium 

 lycopersici) , somewhat resistant to leaf-spot (Septoria lycopersici) . 



Plant large, erect, vigorous ; branches many, long, stout, internodes long. 



Foliage type, standard ; leaves large, deeply divided, smooth, yellowish green, 

 shading the fruit. 



Flowers large ; fruit clusters small, many, scattered. 



Fruit large, oblate, dark red, very seldom cracked; stem-end cavity medium 

 deep, ribbed ; blossom-end basin small, fairly deep ; stylar scar small, irregular : 

 skin medium thick ; vertical section short, oval ; cross section round, smooth 

 except near stem ; walls thick, firm, juicy, evenly colored ; cells many, small, 

 irregular, well filled; seeds fairly numerous,. medium large; pulp medium thick; 

 core not defined ; flavor pleasantly acid. 



The Norton is a selection from the Stone, which has been dis- 

 tributed both as F 20 and as Norton by the Office of Cotton, Truck, 

 and Forage Crop Disease Investigations and as Wilt-Resistant Stone 

 by Prof. C. E. Temple in Maryland. The original fruit from which 

 it descended was selected by Mr. J. B. S. Norton, of the University of 

 Maryland, and with several other seed samples was given to the writer 

 for trial in the spring of 1915. The fruit produced by this selection 

 was exceptionally good for the conditions under which it was grown. 

 The plants, though with one exception badly infected, showed some 

 resistance to wilt. One plant contained only a mere trace of infec- 



8 As some of the seed of this variety which was distributed in 1919 and 1920 was 

 found to be impure, having given several different off types of tomatoes, a result, it is 

 believed, of accidental crossing in the seed-production fields, the seed has been withdrawn 

 until it can be fully purified.
