and the resin flows from under the bark at the top of the 

 wound. Every week they stimulate it by removing a small 

 layer of wood, and the resin which was a little slackened begins 

 to flow better again. It is received in earthen jars, which are 

 put under the incision at the foot of the tree. It is gathered 

 from the month of May to the end of September. When the 

 turpentine, which is liquid, has been extracted from it, the 

 resin, which is hard and brittle, remains. 



The Firs may be known by having their leaves arranged like 

 the teeth of a comb ; the cones are cylindrical, and formed of 

 slender scales. The firs are large trees which only grow on high 

 mountains. Their trunk is always very straight, and is used to 

 make masts for ships. The fir also yields resin, but not abun- 

 dantly, and people are contented to collect what flows naturally 

 and which is found in large lumps on the trunk. This resin is 

 more esteemed than that of the pine. But the best is that which 

 is called Venice turpentine, and is obtained from the larch tree. 



The Cedar is a beautiful tree which 

 was originally brought from Mount 

 Lebanon, but which is now frequently 

 grown for ornament, as it is very 

 hardy. The wood generally -em- 

 ployed for making lead-pencils is the 

 Bed Cedar of North America, Juni- 

 perus Virginianus. 



The Yew and the Juniper do not 

 bear cones like other coniferse, but 

 berries, and the berries of the yew 

 are red. Yew-wood is also highly 

 valued for its elasticity, and it is 

 used for making bows.
