HICKORIES 175

 necticut, but I do not know of a pecan tree north 

 of Long Island that matures its nuts. We may find 

 in the future that some of the pecans from Indiana 

 or Iowa will grow and ripen well-filled nuts as far 

 north as southern Ontario, but as a commercial 

 proposition, however, we had better leave the devel-

 ciples one may expect to get much better results in 

 the north from trees which belong to the north. 

 Several of the hickories, walnuts, and hazels are 

 worthy of as much attention in the north as has 

 been given to the pecan hickory in the south. The 

 development of the pecan in the south has become a 

 matter so highly specialized that I shall make only 

 casual reference to the subject in these pages, leav- 

 ing the investigator to obtain his information from 

 the literature of the transactions of the National Nut 

 Growers' Association and from books like that of

 certain kinds of pecan trees which may be grown 

 to advantage for household purposes without regard 

 for the market question. Let us make comparison 

 between the pecan and the large extension of range 

 belonging to other fruit trees. Most of the fruit 

 trees belonging to cultivation were the ones which
