POP 



POP 



common Poplars. The branchlets in the Altaic 

 tree arc more slender, and rcd-likc; in ilic Dau- 

 rian thick, short, knobbed, and wrinkled, with 

 a yellow skin sometimes of a very deep colour: 

 the leaves in the rod-like variety ovate- acianii- 

 nate, in the Altaic commonly lanceolate; in 

 the common Danrian ovate and thicker, -o as to 

 be in a manner coriaceous ; in both very sharp, 

 serrate, quite smooth, shining as if varnished, 

 flecp green above, pale underneath : anients ter- 

 minatino-, thick, the female ones ripening in 

 Jutie; containin.?; ovate thick rugged capsules, 

 subcalycled wilh the receptacle, scarcely pe- 

 tluncled. 



The sixth species is resinous, like the pre- 

 ceding; but the leaves are ditlerent, being hol- 

 lowed next the petiole and drawn out at the 

 point. It flowers earlier, as in March. It is a 

 native of Canada. 



The seventh is a native of North America, 

 flowering in March and April. 



The eighth species is a native of Canada, 

 flowering in May. 



The ninth resembles the tenth species iia 

 growth and foliage. It is a native of the islands 

 of the Archipelago, flowering in March .and 

 April. 



The tenth species is a large tree, having nu- 

 merous branches, veined and angular, the leaves 

 bioad and slightly serrate : flowers in loose 

 aments, making little show. It is a native of 

 Virginia and New York, flowering in April 

 and May. 



The eleventh shoots very strong, and is gene- 

 rally cornered, covered with a light green bark 

 like some sorts of willow. The leaves upon 

 young trees, and also upon the lower shoots, are 

 very large ; but those upon older trees are 

 smaller : as the trees advance their bark be- 

 comes of a lighter colour, approaching to gray : 

 the aments are like those of the third sort ; and 

 the anthers are purple. It grows naturally in 

 Carolina, where iit becomes a very large tree, 

 and flowers in March. 



Cidtuie. — All the sorts are readily increased 

 by cuttings, layers, and suckers. 



The planting of the cuttings is the most expe- 

 ditious mode of raising all these trees, as they 

 grow freely without any trouble, when made ei- 

 ther from the young year-old shoots, a foot and 

 a half in length, and planted a foot in depth, or 

 large truncheons of two, three, or more vears 

 crowth, from about a yard to five or six feet 

 lonsr, planted in moist places : though thefe 

 large cuttings or truncheons are not |)roper for 

 general plantations, only in some particular 

 parts, as in a marshy or watery situation, where 

 shade and shelter, &c., may be required as soon 



as possible, in which they maybe planted filially 

 to reiDain, ])atting them ii> to the depth of one- 

 or two ftet. 



In order to raise plants for regular plantations, 

 or for handsome standards, it is the best method 

 to raise them principalK' from young cuttings of 

 one year's growth, or two at most. These young 

 cuttings should be made about fifteen or eigh- 

 teen inches long, and planted out in nursery- 

 rows two feet asunder, placing each cutting two 

 parts or half-wav in the ground, and about a 

 foot distant in the lines, they readily take root, 

 and make good shoots the following sunmier, 

 care being taken to trim off the strasrgling late- 

 rals in order to encourage the leading shoot to 

 grow straight, and rise more expeditiously in 

 height : after having had from two to four or 

 five vears growth, in this situation, they may be 

 filially removed for the purposes for which they 

 are wanted. 



The layers may be laid down in autumn, 

 choosing the lower young shoots, which are 

 convenientlv situated, laying them by slit-lay- 

 ing. They v.ill be well rooted, and fit to remove 

 by the autumn followins:, in nursery-rows, to 

 have two or three years growth. 



The suckers, which souse of the sorts send 

 up in abundance from the roots, as the fifth 

 sort, may be taken up after the fall of the leaf, 

 and be planted in nursery-rows, as directed ibr 

 the cuttings. They form good plants in two 

 years. 



The plants raised in anv of the above methods, 

 after having obtained from two or three to five 

 or six years growth, are of a proper size for fur- 

 nishing plantations, or other places. 



These trees are also capable of being raided 

 from seed, if care be taken to gather a quantity 

 as soon as ripe; and sow them in autumn, in 

 beds either broad-cast or in drills, half an inch 

 in depth. 



These trees may be eiTiployed in assemblage 

 for ornanjcnt in out-grounds, which are de- 

 tached from fine lawns and walks, as on ac- 

 count of the great litter the falling of their cat- 

 kins in some sorts occasions, they are improper, 

 but are excellent for planting towards the boun- 

 daries of parks, padilocks, and fields, the sides 

 of rivers and brooks, and to intersperse with 

 other trees in large plantations, in any interior 

 parts. The White Poplar, the Carolina, Ta- 

 camahaca, Lombardy and Athenian Poplars, 

 are proper to introduce as ornamental trees, and 

 are finely adapted to be employed in assemblage 

 in forming large avenues, open groves, and 

 clumps in parks, &c., though any of the sorts 

 are eligible on the same occasions to increase 

 the variety ; and all the sorts may be employed
