PART in. 



yellow pine for floors that are frequently washed ; as the resin with which it 

 is impregnated renders it finer and more durable. It is used for ship pumps, 

 and as fuel by the bakers and brick-makers of New York and Philadelphia ; 

 and from the roots is procured lampblack. The principal use of this tree is, 

 however, to furnish tar and turpentine. The essence of turpentine, used in 

 most parts of America for painting, is prepared from this tree. 



Commercial Statistics. Price of cones, in London, 2s. per quart. Plants, at 

 Bollwyller, are 1 franc 50 cents each ; and at New York, 50 cents.

Spec. Char., $c. Leaves in threes, very long. Male catkins erect, 

 incumbent. Cones ovate ; scales having very small mucros. 

 (Michx.} Buds, on young trees (see Jig. 2128.), 

 from ^in. to -^-in. H1 length* and from $ in. to 

 A in. in breadth ; conical, dark brown, and very re- 

 sinous ; buds on old trees as in Jig. 2127. Leaves 

 (see fig. 2129.), in the Dropinore specimens, from 4 in. 

 to Gin. long; in Michaux's figure, upwards of 8 in. 

 long. Cones 2^ in. or Sin. long, and l|in. or 2 in. 

 broad ; egg-shaped ; scales |- in. long, and f in. broad, 

 with the apex depressed, and terminating in a slender 

 prickle. Seed very small ; with the wing, from f in. to 

 |. in. in length. Cotyledons, ? The cones and leaves of the 

 trees of this name at Dropinore, and the circumstance of there 

 being trees at 

 Pain's Hill with 

 cones of different 

 sizes and shapes, 

 but all on three- 

 leaved pines, and 

 all evidently of the YVda fa- 

 mily, induce us to believe that 

 P. rigida and P. serotina are 

 only different forms of the same 

 species. 



Description, $c. The pond pine, 

 according to Michaux, rarely ex- 

 ceeds 35 ft. or 40 ft. in height, with 

 a branchy trunk from 15 in.to 18 in. 

 in diameter. The leaves are ge- 

 nerally 5 in. or 6 in. long, and 

 sometimes more. The male cat- 

 kins are straight, and about ^ in. 

 long. The cones are commonly in 

 pairs, and opposite to each other ; 

 they are about 2 in. long, nearly 

 2 in. in diameter, and egg-shaped ; 

 the scales are rounded at their ex- 

 tremities, and armed with fine short 

 prickles, which are easily broken 

 off, so that in some cases no ves- 

 tiges are left of their existence. 

 The cones arrive at maturity the 

 second year ; but they do not shed 

 their seeds till the third or fourth
