THE PLUM, Prunus. 



Of this fruit seventeen varieties were planted in the spring of 1888,^ 

 several of which bloomed this season, but failed to produce fruit. 



Fifty-nine additional varieties were planted last spring. Including both 

 plantings the list embraces the following: 



Of P. Domestica (the garden or European species), thirty-five varieties. 



Of P. Americana (the native wild plum q^the north), eighteen varieties. 



Of P. Chicasa (the native plum of the southwest), seven varieties. 



Of the recently introduced Japan species, fifteen varieties. 



Also Pissard, which is an alleged variety of the Cherry plum {Myra- 

 holan). 



Six of the varieties imported by Prof. J. L. Budd, of which trees were 

 received from him, are included among the varieties of domestica as given 

 above. 



So large and varied a collection has been gathered with the purpose to 

 supply the means of observing their comparative ability to resist the vari- 

 ous maladies to which, in our climate, both tree and fruit have proved 

 liable, with the hope to discover, among them, varieties, or possibly 

 species, adapted to profitable cultivation here, where the cultivation of thi& 

 fruit has, for many years, been practically abandoned. 



Another, though incidental, object has been to provide a collection upon 

 which the varying results of the use of insecticides and fungicides, as well 

 as other appliances, upon the several species and varieties, can be satisfac- 

 torily observed and compared, with at least the possibility that such 

 wider field of experiment and oi)servation may evolve processes or varieties, 

 one or both, by means of which the old-time success of plum culture in 

 southern Michigan may be at least partially renewed. 



As in the case of all the tree fruits, planted during last spring, two 

 adjacent trees have been planted of each variety, so far as trees were at 

 hand, and vacancies left, where trees were lacking, to be subsequently 

 filled. 



Of those planted last spring, four trees have died, those being from a lot 

 received from Georgia during the blizzard of last March, which ruined the 

 fruit crops of this region. 



Vacancies were also left for the fifteen lacking trees, making nineteen 

 vacancies to be filled, to supply nearly all which we now have trees of our 

 own growth. 



The only insect which has proved troublesome upon the plum this 

 season is the slug {Selandria cerasi), which has proved unusually persist- ' 

 ent, new colonies having made their appearance as late as the middle of 

 September. 



The fungus known in common parlance as plum pockets, or plum bladders 

 {Taphrina pruni, Fckl.), which usually attacks the fruit, developed on
