THE CANADIAN HORTICCLTDKIST. 



and adds that of all the older sorts 

 only the Blue and Yellow Orleans, 

 cooking varieties from the Island of 

 Orleans, below Quebec, came through 

 unharmed. Two Russian trees received 

 by him from Prof. Budd. without name, 

 are quite uninjured. 



The writer concluded by saying? 

 " that in the experience of this test- 

 winter of 1884-'85 the value of the tree 

 fruits of North- Eastern Europe, and 

 especially of Russia, looms up grandly 

 as the only salvation for the fruit 

 growers in the cold north in Amei"ica." 



PERMANGANATE OF POTASH. 



Mr. N. Robertson, Superintendent 

 of Government Grounds, Ottawa, writes 

 to the Gardener's Monthly that after 

 reading in the Canadian Horticulturist 

 the extract which was taken from the 

 Garden, England, giving the beneficial 

 effects of watering plants with a solu- 

 tion of Permanganate of Potash, he was 

 induced to give it a trial. The result 

 of his trial fully corroborates what was 

 said of it in the extract from the Garden. 

 He says an amateur of considerable 

 experience told him that his plants 

 never looked as well as they do this 

 year, and adds that his primulas are 

 especially fine. Green fly has entirely 

 disappeared. He has doubled the 

 quantity and syringes with it every 

 second night. Mildew on roses has 

 disappeared, and the plants seem to 

 have renewed \-igoi-. In using it for 

 syi'inging he finds that when it is 

 allowed to stand mixed for any time it 

 is liable to leave marks on the leaves, 

 but not if it is newly mixed. Although 

 it kills green fly, he says that it will 

 not prevent new broods from coming, 

 and every one ought to know how fast 

 that is. Permanganate of Potash is a 

 cheap article, and can be easily pro- 

 cured. Will not other gardeners give 

 it a trial, and give the public the bene- 



fit of their experience. The English 

 gardener took as many crystals as 

 covered a six-penny piece and dissolved 

 them in one gallon of water for water- 

 ing the soil, but for syringing used 

 double the quantity of water. 



THE CABBAGE AND ONION MAGGOT. 



Professor Lintner, New York State 

 Entomologist, in a communication to 

 the Country Gentleman, says, " per- 

 haps nothing better for the purpose of 

 killing the pupae could be used than 

 gas-lime, fresh from the works, spread 

 upon the ground after the removal of 

 the crop, at the rate of two hundred 

 bushels per acre." This is suggested 

 because the maggots pass the winter in 

 the ground in the pupa state near the 

 place where the cabbage or onions 

 grew, and the gaslime would be strong 

 enough to kill them. The professor 

 adds that thorough ploughing and har- 

 rowing the ground several times, with 

 intervening intervals, would kill a large 

 proportion of the pupse. 



A PROMISING NATIVE PLUM. 

 At the last meeting of the Fruit 

 Growers' Association several of the 

 members spoke of a red plum of good 

 quality, especially valuable for canning, 

 the tree of which was very hardy and 

 very prolific. It was described as being 

 of good size, nearly as large as the 

 Lombard, sweet and ripening early. 

 From what we could leai-n on further 

 inquiry we believe that this is a variety 

 of the wild plum of the Country which 

 has been cultivated by the inhabitants 

 of that section on account of its good 

 qualities, and that it deserves attention. 

 It will be much more valuable to us 

 than the Miner or Wild Goose which 

 are shy bearers here, and ripen late. 

 We hope to receive some samples of the 

 fruit when ripe, and if we do shall 

 give our readers a more complete des- 

 cription of its appearence and qviality.
