Results of the experiments. — The instructive results of tliis series will 

 be found scattered tbrougli tlie synopsis. Its main object was, of course, 

 to corroborate the other work, and the success met with Avas even 

 better than was expected. Tlie effect of cross-pollinating" was even more 

 striking than at Eochester. Although a considerable number of 

 blossoms on the Bartlett, Anjou, and Clairgeau were self-i)ollinated, not 

 a single fruit came from them. On the other- hand, cross-pollination 

 gave a fair i^er cent of fruit. The remarkably clear-cut results on these 

 trees, as compared witli those at Eochester, where an occasional fruit 

 resulted from self-pollination, was no doubt due to their rather low 

 state of nutrition. The Buffum, Doyenne d'Alen9on, Heathcote, and 

 Mannings Elizabeth, however, gave very high per cents under self- 

 pollination, showing that with certain varieties the need for cross- 

 pollination is not so pronounced.
