I have not been troubled much with mildew. A few of the vines 
of my first planting mildewed badly. I dug them out and planted 
others in their places; since that time I have not been troubled very 
much. Of course, some varieties are more subject to mildew than 
others, and as the list of vines to select from is large it is not hard 
to find a sufficient number of good and fairly healthy vines to suit 
almost any one. Some of my favorites are Moore’s Early, Worden 
and Concord. I would not plant many Concords; I like the Worden 
better, and I think it is of better quality and it is earlier, which is a 
greai deal inits favor. And I like the Delaware and Brighton; the 
Brighton is a very fine grape and bears very fine bunches. The 
Lady is a very good white grape. I have the Pocklington and Ni- 
agara, but I don’t think much of either of them. A few years ago I 
got a few vines of the Green Mountain,and from what little I know of 
itin the limited time that I have had it,l am well pleased with it. The 
bunches are very compact, the berries rather small, similar to the 
Delaware, and the quality is good. It ripens early,and the vine 
seems vigorous and healthy. Of course, there area great many good 
varieties, but I think it is not advisable to plant too great a variety:

INSECTS IN SOUTHEASTERN MINNESOTA. 
Insect of some species were more plentiful and damaging to the 
horticulturist in 1894 than in the preceding year; especially was 
this the case with such as feed upon the cabbage family. The 
cabbage crop was very seriously injured by the European cabbage 
caterpillar larvae, of the Pieris rapea (Linn.). They made their first 
appearance very early in the season, and at least three broods of 
them were perfected. The hot, dry weather seemed favorable for 
their most perfect development, while the slower growth of the 
plants place them at adisadvantage for resisting the attacks. There 
was also a noted scarcity of the parasitic. insects that usually prey 
upon them, such as ichneumon flies, black wasps and dragon flies. 
The best remedy we know of for the cabbage worm is the pyrethrum 
powder, viz: one pound mixed in four pounds of flour, dusted over 
the plants when wet with dew. As is often the case in dry seasons, 
the cabbage aphis (Aphis brassicae) was also very troublesome. It 
infests the under side of the leaves and has a whitish,mealy appear- 
ance. 
The potato beetle and their larvae were much more numerous and 
destructive than im the preceding year, and the farmers say it re- 
quired closer watching and more frequent spraying with Paris green 
than usual to save thecrop. I saw on my place more of the beetle 
than common,and one day the larvae were so numerous that I feared 
that I should have to follow the example of my neighbors and give 
thema dose of green, but, happily, at this juncture the rose-breasted 
grossbeaks, that were rearing their young in adjoining apple trees, 
friendly soldier bugs, lady birds and other parasites came to my
