panicles of small flowers are also very pretty. A finer 

 effect would be obtained from these shrubs by isolating 

 them on the grass than in any other way. 



*Tanacetum vulgare var. crispum. — A very ele- 

 gant variety of the common tansy, much dwarfer in sta- 

 ture, and with smaller emerald-green leaves, which are 

 very elegantly cut, and have a crisped or frizzled appear- 

 ance. It is quite hardy, and forms an effective ornament 

 on the margins of shrubberies, near rockwork, etc. It 

 does best fully exposed, and probably the only way in 

 which it can be benefited after planting — in deep and 

 rather moist soil it does best, but will grow "anywhere" — 

 is by thinning out the shoots in spring, so that each re- 

 maining one shall have free room to suspend its exquisite 

 leaves ; thinned thus, it looks much better than when the 

 stems are crowded, and of course, if it is done in time, 

 they individually attain more strength and dignity. The 

 flowers should be pinched off before they open. Britain. 



Thalia dealbata. — This is one of the finest aquatic 

 plants which we can employ in the embellishment of 

 pieces of water, streams, etc. In a warm and sheltered 

 position, and on a substantial and rich bottom, it grows 

 vigorously, sometimes attaining a height of 6 ft. The 

 best mode of growing it is in pots or tubs pierced with 

 holes, in a mixture of stiff peat and clayey soil, with a 

 portion of river-mud and sand. In winter these pots or 

 tubs may be submerged to a greater depth, and the 

 plants be thus effectually protected. It would not attain 

 the above size out of doors except in warm places in the 

 southern counties, in which it might be planted out 

 directly without taking the precautions above described.
