P ni<rra grows wild only in New England, Canada, Nova Scotia, and the colder climates north- 

 ward It generally occupies a cold, moist, sandy soil. Its height in such places is from thirty to forty 

 feet and its diameter from One to two at. about the middle of the trunk, which is uneven, and the 

 branches reach to the ground. The* bark, both of the trunk and the branches, is blackish, but the wood 

 has a reddish white colour; the latter is light, and full of large veins. In cases of necessity, ,t is used 

 by the Americans for building fishing-boats, and small vessels. The top of the tree is _ impregnated 

 with fine resinous particles. It is at its greatest strength in the spring, when an extract is made from 

 the leaves and young shoots, as well as from those of P. alha, with which Sp^ce beer is brewed. 

 Some persons are of opinion that the extract made from the former species, is better than that made 

 from the latter The Ica^c. are little more than half an Inch in length, slender, tetragonal, and of a dark 

 gin olt The cones assume an oval shape, but they are small. The scales of these are of a 

 S iTceous texture, and large in proportion to the dimensions of the eone. ^^ ^ana a and Nova Scotia 

 the seed ripens about the end of November, but is not shed before the following spring. This 

 not so much cnkivated in this country as it deserves.
