roots of weeds. The caterpillars of fimbria feed 

 upon the young leaves of Willows and Birches 

 after living upon the older leaves in the autumn 

 and passing the winter in a quiescent state. 

 Orbona and subsequa are also common species. 

 The same remedies as are set forth under the 

 heading NOCTUJE may be resorted to. 



TSUGA. 



Hardy evergreen Conifers (ord. Conifera), with 

 comparatively slender and often pendulous 

 branches, spirally scattered, very narrow leaves, 

 and nearly round or oval cones. A number of the 

 species and varieties are of elegant habit and 

 appearance, and they are favourites with the lover 

 of hardy trees. (For cultural details, see PINUS.) 

 The timber of the Hemlock Spruce (canadensis), 

 although elastic, is coarse and loosely built. It is, 

 therefore, not in great demand. The bark of this 

 species is used by tanners, and in Canada it is 

 employed medicinally.

TUBEROSE. 



The Tuberose (Polianthes tuberosa, see also 

 POLIANTHES) is really a half-hardy, tuberous 

 subject, with its natural flowering season in 

 autumn. The double varieties have, however, 

 proved so remarkably amenable to forcing that the 

 plants are generally treated as stove subjects, and 

 the fragrant flowers are in great demand for 

 buttonhole and bouquet work during the greater 

 part of the year, and, given a good batch of " bulbs " 

 (correctly tubers), it is not difficult to supply the 



Tuber (see Trujtte). 



demand. There are several varieties, including 

 Double African, Double American, Double Italian, 

 and The Pearl. Of these The Pearl is the most 

 generally useful, and it is easy to grow, a free 

 bloomer, and dwarfer in stature than the others. 

 For good bulbs a 5" pot is the best size, one 

 bulb in each. The soil must be good two parts 

 of fibrous loam, one part of dried cow manure 

 rubbed through a sieve, and sand. The drainage 

 should be free, and the potting firm. 



It is the usual plan to pot the whole of the 

 tubers as soon as they are received in autumn, and 

 consign them to a cold frame to make roots 

 gradually. Little water is wanted at this stage; 

 in. fact, if the compost is moist to begin with, and 

 the batch is in a north frame or pit, no heavy 

 waterings will be required until the tubers begin 

 to show signs of growth. An occasional sprinkling 

 with the syringe is helpful. As flowers are 

 required, batches of the plants which have started 

 may be introduced to heat, and then liberal 

 supplies of water become necessary. Plenty oE 

 heat, a liberal use of the syringe to keep down red 

 spider and thrips, and liquid manure when the 

 spikes are showing, are other items of culture. 

 After the crop of flowers lias been gathered the 

 tubers may be sent to the rubbish heap ; they 

 are of little further use, although, if planted out 

 in the open border, they now and again throw 

 useful blooms in subsequent seasons. 



A constant succession can be maintained by (a) 

 having a good many tubers and (4) retarding them 

 in a north frame until they are wanted. 



TUBS. 



Where large shrubs and small trees have to be 

 grown in a portable condition for the furnishing of 

 greenhouse or conservatory, wooden tubs are far 

 more suitable to contain their roots than pots. 

 Not only can the tubs be made of any size required, 

 but they are less likely to be broken during 

 shifting. If well made they will last for years, 

 and it will be found false economy to attempt to 

 save by using flimsy material in their construction. 

 Holes must in all cases be bored in the bottom so 

 as to let the drainage water escape readily. The 

 outside may be painted three coats with any 

 colour desired, but the inside should be left bare. 

 If the tubs are over 2' square the corners should 

 always be strengthened with stout iron braces ; 

 these will add to the life of the receptacle by at 

 least 50 per cent. 



Plants growing in tubs should not need such 

 frequent shifting as those in pots. Much may be 

 done to keep them in health by top-dressings of 

 rich soil occasionally, provided that thorough 

 drainage is given in the first place. 



The rustic tubs used for the ornamentation of 

 the flower garden will be dealt with under VASES,

TULBAGHIA. 



Greenhouse or half-hardy perennial herbs (iinl. 

 Liliacea;). The flowers are useless for cutting, 

 owing to the strong, Garlic-like odour possessed by 

 theiiij though their . free-flowering propensities 

 make them worth cultivating. Propagation, by 

 seeds and division. Soil, light, sandy loam.
