Editor ' s Note. The growth habits of Maaspur and Morspur trees are 

 variable in Massachusetts. Thus, it is of interest to note that 

 the same difficulty is being encountered with Starkspur Ultra Mac 

 under Nova Scotia conditions .

Early indications of spur-type variants of Mcintosh from B.C.

 Following in-

 the various

 decided that the 

 Dewar strain was 

 most appropriate 

 for this region. 

 Negotiations with 

 Mr. Dewar led to 

 his forwarding a 

 sample of scion 

 wood to the Re-

 for testing with 

 possible inclu- 

 sion in the mother
