THE 



Whately justly observes, in connection 

 with these structures, that, — 



"Choice arrangement, composition, 

 improvement, and preservation, are so 

 many symptoms of art whicli may occa- 

 sionally appear in several parts of a 

 garden, but ought to be displayed with- 

 out reserve near the house; nothing 

 there should seem neglected ; it is a 

 scene of the most cultivated nature ; it 

 ought to be enriched — it ought to be 

 adorned ; and design may be avowed 

 in the plan, and expense in the execu- 

 tion." 



Mr. Loudon is more practical on this 

 subject, and observes, — 



TETRAMENA mexicanianum. 

 Green-house shrub. Cuttings and seed. 

 Light rich loam. 



TETRANTHERA. Eight species. 

 Stove and green-house evergreen trees 

 and shrubs. Ripe cuttings. Turfy loam, 

 peat, and sand. 



TETRANTHUS Uttoralis. Stove 

 evergreen creeper. Division. Sandy 

 loam. 



TETRAPELTIS fragrans. Stove 

 orchid. Division. Peat and potsherds. 



TETRAPTERIS. Two species. 

 Stove evergreen shrubs. Cuttings. Peat 

 and loam. 



TETRATHECA. Seven species.

of the living-rooms, must depend jointly 

 on the height of the floor of the living- 

 rooms and the surface of the grounds 

 or country to be seen over them. Too 

 broad or too high a terrace will both 

 have the effect of foreshortening a lawn 

 with a declining surface, or conceal- 

 ing a near valley. The safest mode, 

 in doubtful cases, is not to form this 

 appendage till after the principal floor 

 is laid, and then to determine the de- 

 tails of the terrace by trial and correc- 

 tion. 



" Narrow terraces are entirely occu- 

 pied as promenades, and may be either 

 gravelled or paved ; and different le- 

 vels, when they exist, connected by in- 

 clined planes or flights of steps. Where 

 the breadth is more than is requisite for 

 walks, the borders may be kept in turf, 



TETTIGONI A spumar/a. Froth Fly, 

 or Cuckoo Spit. The frothy patches 

 seen in April and May upon the young 

 shoots of hawthorn, lilac, peach, &c., 

 are formed by this insect. As the froth 

 is formed from the sap of the plant, 

 the insect is by so much injurious to it. 

 The froth protects the insect from the 

 sun, from night colds, and from parasitic 

 insects ; but it betrays the insect to the 

 gardener, whose hand is the best re- 

 medy. 



TEUCRIUM. Forty-seven species. 

 Hardy, half-hardy, and green-house 

 evergreen shrubs and herbaceous pe- 

 rennials; some hardy annuals, and T. 

 cubense a stove biennial. The herba- 

 ceous perennials increase by division 

 and seeds; the shrubby kinds by young, 

 cuttings; the annuals and biennials by 



with groups or marginal strips of flowers j seeds. Common soil suits them all. 



and low shrubs. In some cases the 

 terrace-walls may be so extended as to 

 enclose ground sufficient for a level 

 plot to be used as a bowling green. 

 These are generally connected with one 

 of the living-rooms, or ihe conservatory; 

 and to the latter is frequently joined an 

 aviary, and the entire range of botanic 

 stoves." — Enc. Gard.

 ported roots. Turfy loam and peat.
