Tanks. 



In gardens where fountains are not 

 attainable tanks are not only useful, but 

 may be made exceedingly ornamental, 

 either in flower or kitchen gardens. The 

 position in the latter should be in the 

 centre of a broad grass walk lined with 

 pear-trees and standard roses. It should 

 be made with an asphalte composition, and 

 surrounded by rock-work covered with 

 sedums and the different kinds of saxi- 

 frage. In the flower garden its position 

 must be determined by circumstances. It 

 forms a useful and beautiful centre to a hardy 

 fernery, and, if near enough to the house, 

 may frequently, at a very small expense, be 

 provided with a fountain by means of a 

 small gutta-percha tube in connection with 

 the cistern, which is supplied with the 

 force pump of the house. This tube 

 should be so managed as to be remov- 

 able in winter, for fear of frost. The 

 position of the tank in the kitchen garden 

 should be in the centre of the broad grass 

 walk. A simple tank of this kind may be 

 made by digging out the soil in a circle 

 4 feet deep, and puddling it all round 

 with tempered clay, that is, clay thoroughly 

 washed and kneaded, until divested of all 

 silicious soil, and nothing but pure clay 

 remains ; this well rammed round the 

 whole excavation for 9 or 10 inches, is 

 impervious to water. Large stones, or 

 boulders of handsome shape, placed with 

 apparent irregularity, but real symmetry, 

 all round, will form a handsome and use- 

 ful basin ; and if some of the more deli- 

 cate water-plants, as Arums and Water 

 Lilies or Nymphaa^ are planted in large 

 pots in the bottom of the tank, a- very 

 good effect will be produced, and a variety 

 of blooms obtained in late spring or 

 summer. 



Tansy (nat. ord. Compos'itse). 



A perennial herb often found in the present 

 day in old-fashioned gardens, possessed of 

 a pretty feather-shaped leaf, emitting a 

 strong odour and a small yellow blossom. 

 The Common Tansy of the garden is 

 Tanacetum vulgare. It is still used for 

 garnishing dishes, but in olden time was 

 utilised for culinary purposes, being an 

 ingredient in Tansy pudding, to which it 

 gives its name. 



Tarragon, 



This perennial requires a light, rich, and 

 dry soil, and should be grown in a warm

and sheltered position. Propagate by 

 division of roots in March or April, or by 

 cuttings taken in July or August, and struck 

 under a handlight. Cut down at approach 

 of winter, and protect the roots by putting 

 earth and litter above them. 



Te'coma (not. ord. Bignonia'cese). 



Magnificent ornamental greenhouse 

 evergreen twining shrubs, with large and 

 beautiful flowers. They require the same 

 cultural treatment, and are propagated in 

 the same manner, as the bignonia, which 

 see. Possibly the best -known species in this
