EXPERIMENT STATION BULLETINS.

No definite statement of the relative amounts of fruit yielded by the 

 several varieties seemed desirable, under these circumstances, and these 

 are therefore omitted. 



The dates of the origin or introduction are often so uncertain or diffi- 

 cult to determine correctly, that the attempt to tabulate them has been 

 abandoned; and, instead, merely the year during which they were first 

 received and planted is given, as an indication of the extent of their trial 

 here. 



No indications of the attacks of fungi have been observed upon the 

 blackberry during the season. 



They have also been quite generally free from insect depredations,, 

 except that the foliage of several varieties has been attacked and consider- 

 ably injured by leaf miners. Should these make their appearance again, 

 next year, it will, very probably, become necessary to apply a remedy. 



Lucretia dewberry and Early Harvest blackberry open the blackberry 

 season, very little if at all after that of the earliest black caps. The 

 Brunton, very early and tender variety, did duty as Early Harvest for a 

 time, very much to the discredit of the latter, which (the genuine), though 

 small, is very productive, hardy, and even profitable for the market on 

 account of its earliness. 



Thompson (Early) has scarcely yet been brought fairly to the fruiting 

 test here.
