the air is moist these produce tufts 

 of dirty white, dusty fruiting tlireads. 

 These are divided into sections, 

 which, when ripe, separate and form 

 spores. When the fungus is ripe 

 these successively ripen and drop 

 away. We reproduce from the re- 

 port of the Geneva Experimental 

 Station, in fig. 56, a representation of 

 two fruiting threads of this fungusj 

 before the spores have begun to fall 

 away, magnified 250 diameters. 



As these spores can only develop 

 in a moist atmosphere, it is evident 

 that if we could keep our cherries 

 perfectly dry there would be no rot ; 

 but as this is impossible, we can only 



employ preventive measures. They 

 have great vitality, and preserve 

 their generative powers from one 

 fruiting season to another. Some- 

 times a fruit is attacked before it is 

 ripe, and in that case it hangs upon 

 the tree all winter, until the next 

 fruiting season, and the spores are 

 to be found on it during the whole 

 time. Fallen cherries also serve to 

 propagate the fungus from year to 

 year, and therefore it is evident that 

 much can be done by carefully clear- 

 ing up and burning all that is de- 

 ca3'ed, and, where possible, by 

 having pigs under the trees to eat up 

 all that drops. 



NOTES SUGGESTED BY JULY NUMBER OF "CANADIAN 

 HORTICULTURIST." 



BY THOS. BEALL, LINDSAY. 



THE reports on the prospects of 

 the fruit crop in the July num- 

 ber, coming as they do from reliable 

 correspondents from all sections of 

 the Province, make it one of the 

 most valuable numbers yet issued. 

 This number should be studied by 

 every fruit dealer in the country as 

 well, as by every horticulturist. 



When will the idea be exploded 

 that whereas certain fruits, trees, 

 shrubs and plants are affected in- 

 juriously by exposure to the cold, 

 and may with difficulty be grown in 

 a certain latitude, therefore it is folly 

 to attempt their growth at any point 

 further northward ? Many other 

 factors besides latitude must be taken 

 into accoun to determine how far 



north certain fruits, flowers, etc., 

 may be grown. The frost of May 

 28th, 2gth, which prevailed not only 

 over the whole of this Province, but 

 also over the States, both to the 

 south and west of us, did much less. 

 injury in some of the more northern 

 portions of Ontario than in the 

 southern districts. At Ottawa the 

 temperature was only about one 

 degree below the freezing point. At 

 Lindsay about three degrees. At 

 Woodstock, six degrees, while 

 more than six degrees below the 

 freezing point was reported from 

 several places in the neighborhood 

 of I^ochester, N. Y., and south of 

 that city.
