Urst. is a cross <>f "Pondorosa" (103) iqx)!! ^'Marvel" (77) repret- 

 sontod by the fniction 100/77, that is, using the record number 

 of the malt' ])arcnt as the numerator and of the mother as the de- 

 iioiiiinator. Tlio second combination is a result of the cross used 

 as the male ii|mpii the ".Man-el," the double parallel separating the 

 parents in this union. The third is a cross of "Marvel" upon the 

 original cross, and is styled a reciprocal of the previous (2) com- 

 bination. The fourth is a union of the original cross with the 

 "I*on<leri'sa'" as the female. The reader, from the position of the 

 record nnndtei-s and the single and double lines, may quickly note 

 the way in wbich the subsequent breeding of the "Magnus" and 

 "P(»nderosa" has been pursued. 



A ghmce at the fruit sections in Plate VI. will help still fur- 

 ther to give an idea of the fruits under consideration. The "slice" 

 at 1 is of the ])riniary cross as the fraction shows — which is upon 

 a card, an inch sipiare, to serve as a measure of the fruit slice. 

 The enth'a\-or w as to select, as nearly as possible, an. average typical 

 fniit, but the ]»hotogr{rj:)hing was unavoidably delayed until late 

 in tlie season and the l>est fruits were all gone. The section at 

 1 is seen to 1h' very "moaty," a strong characteristic of the "Pon- 

 derosa," and the seed cavities are much broken up and the seeds 

 comj)ara lively few. The fruit, as a whole, is a great improve- 

 ment u])on the "Ponderosa" because, with a much longer polar 

 axis and therefore admitting of more slices, it is more nearly a 

 circle in outline and but little grooved or ridged. This cross gives 

 fruits that rijien <]uite early but the green shoulder is somewhat 

 in evidence in otherwise mature tomatoes, suggesting the great de- 

 fect (d" the "Pondei-osa." Tlie color is a pleasing red, but, if 

 desired, a pink with all other qualities in common with the red 

 may be easily secured and seeds in quantity of the pink-fruited 

 strain have been secured. 



At 2 is >ho\vn a sorption of a fruit of the second cross, as in- 

 dicated by the fraction. This combination secures a medium- 

 sized, sniootJi, a|)ple-shaped tomato with the center less broken 

 than in the <.riginal cross. The reciprocal of the last, shown at 

 :;, produces A fruit of satisfactory size, form and smoothness with 

 the wall thick and the interior thoroughly broken up and the red 

 <'"l"'- uiiilnrndy distributed throughout the whole fruit. 



I'y breeding the original cross, shown at 1, to the "Ponderosa" 

 parent, n fnrn. <.f fruit is obtained that is not as desirable as in
