4. Experiences in Crossing : Our studies of this subject began in 



1889, when several crosses were made with the specific purpose 

 of producing new types combining the most valuable features of 

 existing varieties. Some of the earlier results were published in 

 a bulletin from the Connell University, in 1891 ;* but it will be 

 necessary to repeat some of the statements there made in the 

 present connection. 



In 1889 three distinct series of crosses were made. The first 

 of them, which we called Series A, was the Round White crossed 

 by pollen from Black Pekin (see figures 8 and 3) . These varieties 



represent two widely 

 different types, and 

 it was hoped we 

 could combine the 

 earliness and pro- 

 ductiveness of the 

 former with the 

 beauty of form and 

 color and the excel- 

 lent quality of the 

 latter. 



In the second 

 cross, which we 

 called Series B, 

 Giant Round Purple 

 was crossed with 

 pollen from White 

 Chinese. The first 

 Long White. ^j thesc— figure 9, 



differs little from New York Purple except in size of fruit which 

 is very large. White Chinese differs little in habit from Long 

 White described on page 80, but the fruits are slightly larger and 

 usually curved, (see figure 10). It is a very handsome variety. 

 These two sorts have not been grown in Maine. 



In the third cross. Series C, Long White was crossed with 

 Black Pekin. Long White in this case differed from the sort 

 described under that name on page 80, in that the fruit was 

 shorter, being somewhat ovoid in form, while the color was 

 greenish white. 



The seeds resulting from all of the above crosses were sown in 



1890, and the plants were given conditions as nearly uniform as
