water for this beetle, known scien- 

 tifically as Macrodactylus subspinosus. 

 The method is : Wet two tablespoon- 

 fuls of the powder with water and 

 mix into a paste. Stir this into two 

 gallons of water, and apply with a 

 force pump in a fine spray. 



Niagara Falls Park. — The Gar- 

 dot and Forest, a journal of the very 

 highest standing and of the most 

 correct taste in matters of landscape 

 gartlening, devotes the editorial of a 

 recent issue, to warning the public 

 against allowing this beautiful park 

 to be marred by the erection of 

 museums, monuments or buildings 

 for educational ends, as being wholly 

 out of keeping with the object with 

 which the park has been set apart. 

 Constant attempts are being made 

 to utilize the wonderful privileges of 

 the place for private ends, or to suit 

 a vulgar taste. In the memorial to 

 the Gov-ernor of New York and to 

 the Governor-General of Canada, 

 the great point made Avas that 

 " objects of great natural beauty and 

 grandeur are among the most valu- 

 able gifts which Providence has 

 bestowed upon man. The contem- 

 plation of them elevates and informs 

 the human understanding. They are 

 instruments of education. They 

 conduce to the order of society. 

 They address sentiments which are 

 universal. They draw together men 

 of all n^ltions and thus contribute to 

 the peace of nations." 



Notwithstanding this, it appears 

 that a memorial has already been 

 presented to the New York State 

 Legislature at Albany by the Niagara 

 Hydraulic Electric Company, asking 

 for the privilege of building coffer- 

 dams above the cataract, erecting 

 machinery and boring a tunnel under 

 the bank of the river, and this has 

 passed the committees of both 

 houses. The bill has been checked 

 by the Senate, but its existence 



shows the constant danger to which 

 the attractions of this delightful 

 reserve is subject. 



Spraying for the Plum Cureulio. 



At a recent meeting of the Central 

 Illinois Horticultural Society, Prof, 

 Forbes, the State ICntomologist, 

 gave an address giving the result of 

 his investigations and experiments 

 in reducing the extent of the ravages 

 of the plum cureulio by means of 

 spraying. According to the Prairie 

 Farmer s report. Prof. Forbes stated 

 that it had been found by careful 

 experiment, that the mature inse'ct 

 subsisted on dead and decaying leaf 

 vegetation until the green leaves and 

 fruit appeared. One pound of Lon- 

 don purple or Paris green to 100 

 gallons of water was found to injure 

 the foliage of the peach and plum. 

 Experiments showed that one pound 

 to 500 gallons of water destroyed the 

 plum cureulio in ten days, and this 

 solution was recommended as proper 

 for the peach and plum. The 

 stronger medium killed somewhat 

 quicker. The advice in general was 

 to spray early in the season with a 

 solution found not to weaken the 

 foliage, operated on the basis of say, 

 one pound of Paris green or London 

 purple to 300, 400 or 500 gallons of 

 water, as might be found not detri- 

 mental to the leaves of a species. 

 There seemed no doubt in the mind 

 of the speaker that the cureulio could 

 be killed in the early season by the 

 means recommended. This accords 

 with our experience at Grimsby, 

 that where the poison has been 

 applied early enough in the season, 

 and repeatedly enough, almost the 

 entire plum crop can be saved ; but 

 when delayed until the plums are 

 formed, and cleared of the calyx, 

 the damage will be done before the 

 parent beetles can be destroyed. 

 We await further evidence on this 

 important question.
