Pollination of Fruits. 



[Mai, 



The following also failed to mature fruit in these trials with 

 their own pollen .—Kentish Preserving, Knight's Early Black, 

 Old Kentish Black, Waterloo; and at Merton: — Black Tar- 

 tarian, Bigarreau de Schreken, Bigarreau Noir de Guben, 

 Bigarreau Jaboulay, Governor Wood, Guigne d'Annonay, and

Trials in the pollination of cherries seem to be of special 

 importance, as so many are self -sterile, and some varieties are 

 inter-sterile, or nearly so. Cherries need patient and numerous 

 trials extending over several seasons, for results of one year 

 do not absolutely tally with those of another year. Season, 

 position of trials on tree, health or constitution of the tree, 

 disease, insects, accidents, frosts — all these influence results 

 and make trials advisable on different trees, in different 

 orchards and in different localities. Although the result of 

 individual trials may vary somewhat with the order of blossom- 

 ing, yet the general results are the same year by year, showing 

 the advisability of inter-planting varieties for cross-pollination 

 and demonstrating the value of hive and wild bees in carrying 

 pollen from flower to flower.
