ARE TREES FROM NORTHERN NURSERIES HARDIER THAN THOSE 

 FROM SOUTHERN ONES? 



Many opinions were expressed, but few men had grown 

 trees from different latitudes under such conditions as to answer 

 the question fairly. The answers were in no way decisive and 

 the question is still an open one to be settled only by direct ex- 

 perimentation with trees of the same varieties from North and 

 South grown under identical conditions. 



II. 



The following variations in the species favorable to hardi- 

 ness to cold were noted: 



DOES THE CHARACTER OF INDIVIDUAL TREES HAVE ANYTHING TO 

 DO WITH HARDINESS? 



Answers to this question were very indefinite and often con- 

 flicting. It was held by some, and with a fair show of experi- 

 ence to confirm the contention, that trees naturally high-headed 

 with few branches, long, spindling trunks, branches and twigs, 

 have soft wood and are therefore more susceptible to freezing. 

 On the other hand, that individuals having naturally short 

 bodies,. a goodly number of branches starting low, with short- 

 jointed wood, bright and clear when cut, and thickly set with 

 buds, were the least easily injured by cold. One tree of a 

 variety may be supposed to be slightly more hardy to cold than 

 another through inherent variation, but whether such hardiness 

 can be detected through the character of the growth would 

 have to be determined by carefully conducted experiments and 

 can hardly be proved by such observations as my correspondents 

 are able to make. 



ARE THE SMALL-GROWING VARIETIES WITH COMPACT HEADS 

 HARDIER THAN THE FREE-GROWING SORTS WITH LARGE HEADS? 



Practically all growers say that the compact growing sorts 

 are the hardiest. As would be expected the small-headed varie- 

 ties are those with the least succulent wood. The following 

 varieties are named as being the most compact growers and 

 hence hardier than the average : Hill's Chili, Crosby, Gold Drop, 

 Barnard, Kalamazoo, Triumph, Wager and Fitz Gerald.
