to this soil antl climate. I have 

 planted the Bartlett and Duchesse ; 

 have fruited the former; have seven 

 other varieties; all do well and are 

 perfectly hardy. In my experimental 

 garden I planted last spring twenty- 

 one varieties of plums; twenty-three 

 of grapes ; some quinces, apricots, 

 and eight varieties of peaches ; the 

 latter are by no means sure croppers, 

 but when there is a large crop at 

 Grimsby we have them too. The 

 Concord grape does well here, and 

 the fruit is better in flavor than 

 when grown on sand. The Niagara 

 is tender in the bud, more hardy in 

 the root, but it is not a sure cropper. 

 The Brighton I have not fruited to 

 any extent as yet, but the few 

 bunches we had were delicious ; the 

 flavor is all that is claimed for it — 

 no mildew, and is quite hardy. In 

 strawberries I do very little growing) 

 only a few for the table; but the 

 Downing, which I planted on a little 

 sand bed, were not nearly so sweet 

 as those grown on the clay. Goose- 



berries do well here ; I have Down- 

 ing, Smith's Improved, and a large 

 English variety, which is not the 

 Whitesmith, if I should judge by 

 those I saw in the grounds of our 

 Vice-President; it was on the place 

 when I came, and is a great cropper. 

 I have fruited it six years and seen 

 no mildew. In black caps I have 

 the Gregg, Mammoth Cluster and 

 Souhegan; the Gregg is slightly ten- 

 der, but the berries are so fine and 

 large, though not as good in flavor as 

 Mammoth Clusters or Souhegan; the 

 two last named are perfectly hardy 

 here. The red berries I only grow 

 for home use, as they are hard to 

 start in a dry season. I have the 

 Cuthbert, Turner, and Marlboro', 

 the last named of which does extra 

 well. I trust, Mr. Editor, I have not 

 taken up too much of your valuable 

 space, but having read so often with 

 pleasure in the Horticulturist the 

 experiences of others in fruit-growing 

 on light soils, I thought I would 

 give the result of mine on the clay. 



ON THE DESTRUCTION OF THE PLUM CURCULIO 



BY POISONS. 



ONE of the most important 

 results to fruit-growers of recent 

 studies in economic entomology, is 

 the demonstration of the fact that 

 injury to plums by the Plum Curculio 

 can be prevented, to a great extent, 

 by spraying the trees early in the 

 season with Paris green or London 

 purple mixed with water. This fact, 

 I believe, was first ascertained by 

 practical fruitgrowers, who, finding 

 good results from the use of Paris 

 green against the Codlin Moth, 

 jumped to the conclusion that the 

 Plum Curculio could be destroyed in 



the same way. At the time this was 

 done the known facts in the life- 

 history of the Plum Curculio did not 

 warrant any such conclusion. In 

 truth, the entomologists were mostly 

 inclined to say that injuries by this 

 insect would not be prevented by an 

 application of Paris green to the 

 trees. It was urged that, as the 

 eggs of the Curculio were placed 

 within the tissue of the fruit, the 

 newly hatched larvae would be beyond 

 the poison applied to the surface. 

 In this respect this insect differs 

 from the Codlin Moth, which lays its
