Towards the sources of the Ottawa large tracts of sandy 

 land are entirely covered with red pine ; from which 

 country we principally derive our supplies of that kind of 

 timber. It also grows about Quebec, and is more or less 

 scattered throughout the country. 



Pimis banksiana — Lb. Pinus rupestris — Mx. Gray 



Pine. Chipre? 



" Leaves in pairs, short, rigid, devaricate, oblique, recurved, twisted ; scales 



without pricltles." 



A small tree varying from a few feet in height to thirty 

 feet, according to the nature of the soil. It is rare in the 

 southern parts of the province, but abounds in the north, 

 Capt. Franklin mentions it as growing in a high latitude. 

 There is a solitary locality of this tree at Sillery ; near the 

 highway to Cap Rouge : it is also found at Three Rivers and 

 at St. Paul's Bay. 



Pinus rigida — Lb. Pitch Pine. 



" Leaves in threes, in short sheaths. Cones ovate; scales with reflexed spines." 



A tree about the size of red pine ; found very sparingly 

 in Canada, but grows in abundance on the shores of Lake 

 Champlain. No locality is known near Quebec. The 

 timber resembles red pine, but abounds more in resin ; it 

 is sought after by pump-makers.' Tar and lampblack are 

 manufactured in Vermont by very simple processes. The 

 knots being incorruptible, are found abundantly in groves 

 of this pine, frequently under ground, where they have 

 lain for ages ; these are collected and piled upon a stone 

 hearth, covered over with sod and earth, and set on fire, 

 in the manner of making charcoal. The heat produced in 

 burning causes the tar to leave the knots, and flow over the 

 hearth by a groove cut in it for that purpose. Lampblack
