TREATISE 



the winters are not fo long as ours, they are mofl commonly 

 found in watery grounds, and by the fides of rivulets, yet, from 

 many repeated trials I have made, I find they will not fucceed in 

 fuch places here ; neither ought they to be planted in thin dry 

 land, where frequent w^a-terings in fummer will be required to 

 keep them barely alive. The young branches of this tree, which 

 grow m an a ngular manner, are very fingular : Their leaves are . 

 broader than any of the other forts mentioned ; and, from their 

 buds in the fpring^ ilTues a very fweet balfam. . 



The Balfam Poplar was fent in cuttings from Canada to'; 

 Scotland five or fix years ago, and being propagated with much 

 eafe, are now in the hands of many. It is, of ail the fpecies, by 

 far the moft beautiful and magnificent plant. The leaves are 

 very large, of a light chearful green, and the bark of a fmooth 

 fhining browni/h colour. I have feen it in various foils, both 

 wet and dry, , of a middling good quality, in all which it much 

 exceeds the other forts in luxuriance of growth. Whether it 

 will advance with equal facility as the common kinds, in very 

 poor and expofed fituations, I fhall not yet pretend to determine, 

 as it has not been long enough amongft us to mak& fufiicient 

 experiments ; but, from all the obfervations I have been able to 

 make, it appears a hardy plant, from whence there is reafon to - 

 hope it may; in which event, it will be an acquifition of the : 

 higheft importance, both in point of ufe and beauty to our fo- 

 refts ; and as, if I live, trials fhall immediately be made in the 

 fulleft manner, this circumftance will foon be determined. 



The berry-bearing Poplar was introduced to us at the fame 

 dme, and in the fame manner, as the balfam kind. It is. like*
