EXPERIMENT STATION BULLETINS. 141 



The European (grossularia) varieties only prove reliable in specially- 

 favorable locations, or with special treatment. For general planting, 

 whether family or market purposes, only those usually supposed to be of 

 native parentage can be safely relied on. 



Houghton is the oldest of these, and although the fruit lacks size, and 

 the plant is of straggling habit, it is so thoroughly hardy, vigorous, and 

 productive, and the quality so satisfactory, that it may well, as it does, 

 hold a leading place, even in a list for home use. 



Smith, though the least vigorous of the so-called natives, is yet a 

 healthy though moderate grower, and withal very productive. Its fruit 

 is the largest of the class, as well as of superior quality. With liberal 

 culture and judicious pruning it will, very surely, prove eminently satis- 

 factory, whether for family or commercial planting. 



Downing, though scarcely equaling the Smith, in either size or quality, 

 is yet so sturdy and vigorous, and withal so productive, and the fruit so 

 large and of even size, that it is very generally preferred for commercial 

 planting. 



Industry is an imported variety of R. grossularia, which has been con- 

 siderably disseminated, as being less liable to mildew than others of its 

 species, but several seasons' experience with it, at this place, fail to war- 

 rant such claim. 



CHERRIES, Primus. 



Of this fruit, the Mazzard varieties succeed so imperfectly in Michigan 

 that only a comparatively limited number of varieties of this have been 

 planted. Selections for this purpose have been more largely made of 

 Dukes and Morellos, among them being several of the comparatively recent, 

 and supposed hardy varieties imported by Prof. J. L. Budd of Iowa, from 

 northeastern Europe several of which are apparently identical in habit of 

 growth with the Morellos. Others are designated as belonging to 

 families; among which are grioites, ostheims and others, rarely planted in 

 this country; some of them corresponding, in habit of growth, with the 

 Morellos, while others show the Duke habit or are possibly intermediate in 

 this particular. 



The only insect which has proved especially troublesome, this season, is 

 the cherry slug (Selandria cerasi), fresh colonies of which have rapidly 

 followed each other down to the latter half of September or the beginning 

 of October. 



Little if any injury has been observed from the attacks of fungi.
