our winters, but have succeeded better with summer and autumn 

 sorts. The Tetofsky and Duchess of Oldenburg seem to be proof 

 against almost any degree of frost. Montreal and Irish Peach Apple, 

 quite hardy ; and most of the Crabs, but some of the Crabs fail too. 



Summer apples ripen their wood and drop their leaves early, 

 consequently they are better prepared for the extreme frosts of this 

 section of country. Perhaps my test is rather hard ; our orchard is a 

 rich clay soil, underdrained Q,ver four feet deep, and I thought rank 

 growth and deficiency of lime were the cause of failure, but I have 

 seen the Fameuse in Ottawa city, on lime-stone soil, doing no better 

 than my own. I do not say the amateur cannot grow these varieties 

 by proper summer pruning, slow growth, and suitable soil, but what 

 is wanted for general cultivation are sorts as hardy as the Duchess of 

 Oldenburg Apple and Transcendant Crab, that will thrive on any soil. 

 As far as my experience goes, I am convinced that Ottawa must find 

 new sorts, either of named varieties w^liich have proved hardier in the 

 north-west than the Fameuse, or seedlings grown on her own soil. 



The Common Eed Plum does well here ; but Mr. Bucke gives a 

 wrong idea, on page 168 of the Horticulturist, about the Curculio; 

 they are here in abundance. We smoked the trees with gas tar this 

 year, they were less damaged than usual ; but some trees left to test 

 the tar theory seemed to be no worse injured tlian those that were 

 smoked. The abundant crop this year was perhaps due to some 

 peculiarity in the se'ason, or it may be the Curculios overdid the thing 

 the last few years and starved themselves out 



THE GREEN GRAPE VINE SPHINX. (Darapsa 7nyron.) 



BY W. SAUNDERS, LONDON. 



This insect is common almost everywhere throughout Ontario, and 

 must be familar to every grape grower. The larva is rather a formi- 

 dable looking creature, with a bull-dog sort of look about the head when 

 at rest, arising from its power of drawing the head and two anterior 

 rings of the body within the next segments, and thus unnaturally dis- 

 tending them. In this appearance it simulates the way of a weU bred
