Novelties. 



5-56. Sir, — An agent here is selling peacli trees grafted on Minnesota hazel stock, 

 which he states causes them to be much hardier than on peach or plum stocks, and that 

 they are giving good crops as far north as Guelph. He is also selling the grape vine rasp 

 berry, which he states will do well on clay soil, on which the ordinary raspberries will not 

 do well. Can you offer your subscribers any information with regard to the above ? 



A. G. Heaven, Boyne, Ont. 



We would advise our subscribers to beware of such untried novelties as 

 are here spoken of. If any of them take pleasure in spending money for what 

 they consider the luxury of trying new things worth the expense, but for our- 

 selves we prefer to wait until they have been fully tested by reliable persons 

 before investing. If any of our readers have had any experience with these new 

 things, let us hear from them. 



Japan Plums. 



•55 7. Sir, — Are Japan plums really exempt from black knot, as is claimed for them 

 in the Rural New Yorker of February 18th ? 



1). S. McD., Mahou, JS . S. 



55N. Sir, — Are the following plum trees hardy, and what degree of frost will they 

 stand, — Ogan, Grand Duke, Botan, Spaulding, Monarch, Abundance and Mariana ? 



G. H. Nixon, Hyde Park, Out. 



The Japan plums have not been long enough tested for us to give any very 

 decided opinion regarding them. Mr. S. D. Willard, a noted plum grower of 

 New York State, has probably had the most experience of any one with them, 

 and he stated recently that they appeared to be very hardy in wood, and, so far, 

 exempt from black knot. Just what degree of frost we are not yet prepared to 

 say. We will be pleased to hear from any of our subscribers who may have 

 tested them, or others above mentioned. 



Labels. 



5H9. Sir, — Is Manilla paper, or zinc painted white, the most desirable for tree 

 labels. 



G. H. N., Hyde Pari. 



Manilla paper might answer well, if it is not intended to be exposed to the 

 weather, but the most satisfactory label that has been used by the writer is zinc 

 without paint. Lead pencil marks on zinc, when exposed to the weather, become 

 almost indelible.
