ON VINERIES. 



vines deprived of bark — in fact, the bark is their natural 

 clothing. Loose bark hanging a foot or two from the 

 stem may, of course, be cut off; but the vine should not 

 be scraped nor the bark peeled off, as is often done. 

 Notice how noble our forest trees look with their 

 beautiful bark, protecting the rising and descending sap. 

 I have seen horses eating the bark off trees, but as soon 

 as the bark is removed the tree begins to die. 



Where the thrip is established, it may, with great care 

 and watchfulness, be kept in check. This is effected 

 by sponging carefully with tobacco-water and a little soap 

 — 1 oz. of soft soap and 1 quart of tobacco-water to 

 two gallons of rain-water; boil the soft soap and the 

 tobacco -water together, then add rain-water, making 

 in all two gallons of solution. I have often found the 

 thrip in small groups underneath the leaves, and also, as 

 the season advances, on the tops of the foliage. In 

 sponging the infected leaves, however, great care is neces- 

 sary, as the least drop of the solution falling on the 

 grapes will spoil the bloom and unfit them for table! 

 I recommend smoking with tobacco paper two or three 

 nights in succession. If this be done on a still night, 

 it will kill the young thrip, and also tend to keep the 

 old ones in check. There is another species of thrip 

 (Andonidum vitice), which sometimes appears on the grapes 

 about the time they are making their last swelling ; it 

 can be perceived more plainly on the Muscats and some
