THE CANADIAN' HORTICrLTCKlST. 141 



wliicli is it more at home than in Canada. The tree is very hardy and. 

 Avill thrive vigoionsly in ])hices where the Early Harvest woiihi sutler 

 from the cokl. It receives the double star of great merit in Nova 

 Scotia and ]\faine, Michigan and AVisconsin, and twenty-two other 

 ■ States, and that even as far south as Louisiana and Texas. It is 

 repcfrted as doing well in- the Counties of Glengarry and Carleton, and 

 may with safety be planted in very cold parts of our Province ; yet 

 we have heard of its failing to succeed in Arnprior, in the County of 

 Renfrew. 



It is one of our most handsome fruits, being of full medium size, 

 of a dark crimson, covered with a light bloom. The Hesh is white, 

 crisp and juicy, of a rich acid flavor. It is an excellent cooking apple, 

 and its showy color gives it great popularity in the markets. It begins 

 to ripen before the middle of August, and continues to ripen its crop 

 gradually, so that it lasts for some time. 



These two varieties of summer apples may be safely recommended 

 for general cultivation, and while the Red Astracan is the more hardy 

 sort, and may be planted farther northward than the Early Harvest, 

 yet the latter, on soils abounding in lime, is by no means a tender 

 tree. Having these, the possessor may well be content on the score 

 of early apples, and leave to others the pleasure, and the labor too, of 

 testing new and untried substitutes. 



THE ARCHIPPUS BUTTERFLY. 

 (Danais Archippus.) 



The writer was recently examining one of the species of the milk- 

 weed that is grown in our greenhouses, the Asclepias Curassavica, when 

 to his surprise there were found several of the larvae of the Archippus 

 Butterfly feeding upon the leaves. The plants had been taken from 

 the greenehouse and plunged in a frame for the summer, and the 

 female of this butterfly, in her wanderings about the grounds in search 

 of milk-weed plants upon which to deposit her eggs, with a knowledge 

 of botany far beyond that of many a gardener, had recognized this A. 

 Curassavica as a species of milk-weed upon which the young larvte 

 could comfortably feed. 



It is very interesting to observe tlie habits of insects. They seem 

 to be endowed with some faculties that are not given to animals of a
