GRAPE MILDEW. Prof C. V. Riley, entomologist of the De- 

 partment of Agriculture, summarizing his paper, said: We thus 

 have, indigenous to this country, two mildews that are more par- 

 ticularly destructive to the grape-vine : 



The Uncinula, or the Powdery Mildew, flourishing most in a 

 dry atmosphere, not particularly destructive to our hardier 

 native grapes, and easily controlled by the use of sulphur. It 

 develops chiefly on the upper side of the leaf and produces 

 simple ovoid summer spores and more complex and ciliate winter 

 spores, which are found upon both the leaf and the cane. Intro- 

 duced into Europe many years ago, it is only known there in the 

 conidial as Oidium tuckeri, and works more injury than it does 

 with us. 



The Peronospora, or the Downy Grape-vine Mildew, which 

 ramifies its mycelium in the substance of the leaf and even of 

 the fruit, and develops most in moist or wet weather. It pro- 

 duces its summer spores on the under side of the leaf, and a 

 winter spore in the tissues of the dry and fallen leaves. It is 

 not amenable to sulphur but is checked by a diluted kerosene 

 emulsion in which a small amount of carbolic acid is mixed, but 

 far more effectually checked, and even prevented, by a mixture 

 of slacked lime and sulphate of copper. This should be applied 

 early in the season, say in June, so as to act as a preventive; 

 while the gathering and burning of the old leaves in winter time 

 will assist. This species is more injurious with us than the other 

 and is especially troublesome on the European vines. It was 

 first introduced into Europe in 1877, when it was found in Hun- 

 gary, and has since spread through the greater portion of France, 

 Italy, Switzerland, Austria, etc. 



NOMENCLATURE or FRUITS. President T. T. Lyon of the 

 Michigan Horticultural society said: What classes of names are 

 to be preferred for fruits may fairly be regarded as an open 

 question. We esteem brevity as always and everywhere desirable. 

 The name of the originator or introducer will rarely be found 

 inappropriate; and the same is true of the name of the place of 

 origin, while either will generally possess the advantage of 

 requiring but a single word; while the wish to add a character- 

 izing word but too commonly finds expression in the use of such 

 titles as Pippin, Pearmain, Superb, Favorite, or Beauty, or of 

 political or military designations, designed to convey the impres- 

 sion of superiority, but which have been heretofore so loosely 

 employed, that they have, to persons of experience, at least, long 

 since ceased to convey the impression intended. VV^e cannot ton 

 strongly insist, that more than a single word will rarely be found 

 needful; and that, if characterizing words be employed, the 

 strictest honesty in their use be rigidly adhered to. If (as 

 we infer should be the case) it be the purpose of the society to 

 adhere strictly to its rule respecting objectionable names, it
