Spraying For Thrip. 



1 175. Sir, — Can you inform me the best solu- 

 tion for sprajang indoor grapes ? Last year my 

 grape vines were almost ruined by "thrip," and 

 am afraid they will be so again. I have been 

 spraying them with cold water in the evenings. 

 I have a fine lot of the fruit, and it is on the new 

 wood. You will very much oblige me. 

 Yours very truly, 



Cobourg, John Hayden. 



We have had good success spraying out- 

 door roses for thrip with Gillet's lye. We 

 applied it with Mitchell's hand sprayer, a 

 sort of atomizer, which throws an exceed- 

 ingly fine vapor. We used a pound to five 

 gallons of water, but found that this was 

 injurious to the leaves. We would only use 

 half a pound to ten gallons next time, and 

 then spray in very fine mist. Most people 

 use less coarse a spray. We would expect 

 this same material useful in the case of 

 greenhouse grape vines affected with 

 thrip. 



We would also suggest trying the appli- 

 cation of dry insect powder, and leaving all 

 doors and windows closed, or the house 

 might be fumigated with dry insect powder, 

 a thing that has been found effective in 

 clearing out mosquitos from houses or tents. 



Apples for Prince Edward Island. 



1176. Sir,— Taking fruit and tree of Ben 

 Davis as a standard of comparison for shipping 

 to Great Britain in winter, in early bearing, 

 hardiness, vigor, productiveness, freedom from 

 spot or rust, color, etc., what would you say in 

 favor of Ontario, Gano, Stark, York Imperial, 

 Sutton Beauty i ranberry Pippin? 



Novice. 



Georgetown, Prince Edward Island. 



As Dominion Superintendent of Horticul- 

 ture at the World's Fair, Chicago, the 

 writer had much experience with apples 

 from all sections of the United States and 

 Canada, and one conclusion was forced 

 upon him, viz., the great variation in the 

 same apple under different conditions. The 

 Western Ben Davis was a magnificent apple, 

 the best apple for the commercial orchard 

 in certain States, the Baldwin of Western 

 New York is proverbial, the Spy in On- 



tario cannot be excelled by any other apple, 

 nor the Newtown Pippin of the Alleghany 

 mountains of Northern Pennsylvania. In 

 certain parts of Ontario the Ontario apple 

 is a magnificent success, far superior to the 

 Ben Davis ; in others, as for example in the 

 Niagara District, the Cranberry Pippin is a 

 finer selling apple than the Ben Davis, al- 

 though not by any means so regularly pro- 

 ductive. At Trenton the Stark is grown 

 extensively and counted one of the best 

 commercial apples. York Imperial and 

 Gano are reported to be very successful in 

 the Middle States, and Sutton Beauty in 

 New York State. But so far as we know 

 the various apples have never been fairly 

 tried or reported upon in Prince Edward 

 Island, and varieties which are very superior 

 in other places to Ben Davis might prove a 

 g-reat failure in P. E. Island. 



Apple Blight. 



1 1 77. I would like to ask if you can suggest 

 any preventive for "apple blight," which has 

 been ver\' severely felt here this season and last. 

 I put on a number of jrrafts last spring with the 

 very best results, but they are nearly all killed. 

 In common with other sufferers here I would be 

 very glad to know the cause, and if there is any 

 means of combatting it. 



Ottawa. A. H. Taylor. 



No remedy is known for apple or pear 

 blight. It is very injurious some seasons on 

 certain varieties, and then again of quite 

 rare occurrance. Some advise cutting off 

 and burning all affected branches, but this 

 is not alwavs effectiv'e. 



Pruning add Planting Evergreens. 



1178. When is the right time to prune ever- 

 greens, especially Norway Spruce and Cedars ? 

 And can those trees be successfully planted after 

 the season's growth is over, or in midsummer ? 



Brockville. I. Richards. 



Evergreens may be pruned at any time of 

 the year, as there is no time when they are 

 leafless. 



Transplanting of evergreens is best done 

 when the trees are dormant, or just before 

 or just after the summer growth. The
