AMEEICAN BLIGHT. 37 



The variety called the " Northern Spy " was raised in 

 America, and was also introduced here by Messrs. Thos. 

 Lang and Co. It is said to be superior in every way to 

 the u Majetin," and but little else is now used on which to 

 work young trees of the apple. Another variety, said to be 

 superior even to the "Northern Spy, "has been raised by Mr. 

 J. C. Cole, whose father, the late T. C. Cole (the pioneer 

 fruit-grower of Victoria ), has always been to the front in 

 matters pertaining to high-class fruit culture. The name 

 of the new blight-resisting stock is " Perfection Paradise. " 



Some of the advantages which the "Northern Spy" 

 possess over that of the " Majetin" are that it is much 

 hardier in its nature, and its roots are not nearly so easily 

 damaged in lifting as in the former variety. Doubtless 

 there are some persons who would like to know the reason 

 of the non-blighting stocks being distasteful to the aphis, 

 and, for the benefit of such, I have here given the results 

 of the analysis as ascertained by the late Mr. W. Johnson, 

 Government Analyst, being a reply to a letter forwarded 

 to him on the subject by the late Mr. Treen. Mr. 

 Johnson says: "I have made an examination of the 

 young apple trees sent by yourself, the one being a crab- 

 apple, and much infected with a species of white woolly 

 blight; the second one, the Majetin, being quite free from 

 blight. Both were digested in water, and the infusion con- 

 centrated by evaporation. The total amount of extractive 

 matter was as follows : From 2^-oz. weight of dried plants 

 each No. 1, Crab, 86*7 grains; No. 2, Majetin, 108 

 grains. The "Majetin" was more astringent to the 

 palate than the " Crab," but otherwise very similar. The 

 residues left after exhaustion with w r ater were then ignited, 

 in order to ascertain the nature of the ash left. Weight 

 of ash Crab, 33*3 grains; Majetin, 33 grains. The 

 total amount of ash was therefore nearly the same. Upon 

 being analyzed the following results were obtained : 



Crab. Majetin.
