diseases of the trachea. Nat. ord., Bell- 

 worts [Carapanulacese]. .Linn 5-Pen- 

 tandria 1-Monogynia.)

 hotbed in spring ; also by cuttings of young shoots 

 in sandy soil, in April, o"r at the end of summer ; 

 sandy loam and a little vegetable mould.

TRACHYHE'NE. (From trachys, rough, 

 and hymen, a memhrane ; channels of the 

 fruit. Nat. ord., Umbellifers [Apiaces?]. 

 Linn., 5-Pentandria l-Monogynia.) 



All the following are greenhouse, New Holland, 

 evergreen plants, except cceru'lea. The annuals 

 never do much good in the open air, however 

 raised ; but if sown in a gentle hotbed in March, 

 pricked out and potted, and flowered in the green- 

 touse in summer, they will reward the trouble ; 

 sandy loam and leaf-mould ; shrubs, cuttings of 

 young shoots under a bell-glass, in sandy soil ; 

 sandy loam and fibry peat. Winter temp., 40 

 to 50.

TRADE SCA'NTIA. Spiderwort. (Named 

 after J.Tradescant, gardener to Charles I. 

 Nat. ord., Splderworts [Commelinacese]. 

 Linn., 6-Hexa.jidria I-Monogynia.) 



All blue-flowered, except where otherwise men. 

 tioned. Annuals, by seed ; perennials, by divi- 

 sions in spring ; rich, light loam ; those requiring 

 the greenhouse and stove will thrive better from 

 having a little peat, and they should be well 

 drained.

TRAILERS. See CREEPERS. 



TRAIN OIL. See ANIMAL MATTERS. 



TRAINING has for its object the render- 

 ing plants more productive either of 

 flowers or of fruit, by regulating the 

 number and position of their branches. 

 If their number be too great they over- 

 shadow those below them, and, by exclud- 

 ing the heat and light, prevent that ela- 

 boration of the sap required for the 

 production of fructification. If they are 

 too few the sap is expended in tbe pro- 

 duction of more, and in extending the
