The wood warps quite easily, and in consequence is 

 rarely used by the natives. London says " it was discov- 

 ered by Captain Webb, and named Brunoniana by Dr. 

 Wallich in honor of Mr. Brown."

 to about the 51 N. latitude, near Hudson's Bay, in the 

 North. It is emphatically a northern tree, withstanding 

 the exposure and cold storms better than the hot summer 

 suns of warmer climates. A sufficient proof of this is found 

 in the fact that it becomes much rarer in the southern lim- 

 its, and is there only found in the cooler temperatures of 

 the northerly sides of high mountains in the Alleghanies, 

 etc. 



Throughout the southern portion of the Middle States 

 this species is found generally along the larger streams 

 and rivers, but according to Michaux this peculiarity is not 

 bv any means a settled rule ; for in some sections where it

is mingled with the Black Spruce it occurs less frequently, 

 as the soil is more humid. 







Throughout our most northern border and in the British 

 Possessions, the Hemlock Spruce forms vast forests, stretch- 

 ing for hundreds of miles, and is frequently unassociated 

 witli any other species, but occasionally may be found in 

 company with the Black Spruce, White Pine, and other 

 trees. Nuttall mentions that it was collected by Dr. 

 Scouler on the north-west coast of America, and was also
