yellow pine for floors that are frequently washed; as the resin with which itis 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 inmost parts of America for painting, is prepared from this tree.

Commercial Statistics. Price of cones, in London , 2s. per quart. Plants, atBollwyller, are 1 franc 50 cents each; and at New York , 50 cents.

Spec. Char., fyc. Leaves in threes, very long. Male catkins erect, a,incumbent. Cones ovate ; scales having very small mucros. Ji(Michx .) Buds, on young trees (see fig. 2128.),from -Ajin. to -Ag-in. in length, and from ^ in. to flfja in. in breadth; conical, dark brown, and very re- Jn!sinous; buds on old trees as in fig. 2127. Leaves(see fig. 2129.), in the Dropmore specimens, from 4 in. pJlto 6 in. long; in Michaux’s figure, upwards of 8in. ]1|long. Cones 2Jin. or 3in. long, and ljin. or 2in. iffibroad; egg-shaped ; scales J in. long, and § in. broad, (Wwith the apex depressed, and terminating in a slenderprickle. Seed very small; with the wing, from £ in. toA in. in length. Cotyledons, ? The cones and leaves of thetrees of this name at Dropmore, and the circumstance of therebeing trees atPain ’s Hill withcones of differentsizes and shapes,but all on three-leaved pines, andall evidently of the Tse'da fa-mily, induce us to believe thatP. rigida and P. serotina areonly different forms of the samespecies.

Description, Ac. The pond pine,according to Michaux, rarely ex- Iceeds 35 ft. or 40 ft. in height, with Ia branchy trunk from 15 in.to 18 in. ,in diameter. The leaves are ge- ^nerally 5 in. or 6 in. long, andsometimes more. The male cat-kins are straight, and about Jin.long. The cones are commonly inpairs, and opposite to each other ;they are about 2J in. long, nearly2 in. in diameter, and egg-shaped ;the scales are rounded at their ex-tremities, and armed with fine shortprickles, which are easily brokenoft - , so that in some cases no ves-tiges are left of their existence.

The cones arrive at maturity thesecond year ; but they do not shedtheir seeds till the third or fourth
