condition. The flowering season may be 

 extended from January to June if a number of 

 plants are brought into heat successionally. 



For the production of many flowers the 

 bulbs must be well ripened by exposure to 

 air and sunshine during late summer and 

 autumn months. A continual shady and 

 moist treatment will cause the nodes to pro- 

 duce young plants instead of flowers, and, 

 unless a special desire exists to increase the 

 stock of the plant, this often gives consider- 

 able disappointment to the amateur who has 



patiently waited through the long winter 

 months for floriferous results. 



This species is not very particular as to its 

 compost, a mixture of peat, osmunda, and 

 sphagnum giving excellent results. By 

 syringing the plants on favourable occasions 

 a check will be given to thrip and other msect 

 pests. The subject of our illustration is 

 Dendrobium nobile, Berkeley's variety, 

 named m honour of Major-General E. S. 

 Berkeley, an enthusiast of the genus, who 

 died in December, i8g8.

THE general treatment as recommended 

 for last month should still be con- 

 tinued. There must, of course, be 

 instances where a slight departure from the 

 general rule is advisable, but this should be 

 left to the cultivator, who alone must judge 

 of its desirability. No practice is perfect, 

 and in the cultivation of all plants there is, 

 undoubtedly, still some progress to be made, 

 and the person who thinks for himself will 

 make greater strides in the profession than 

 the one who follows a hard and fast line, 



year by year. Even the most successful 

 have many failures to record before they 

 reach the height of their ambition, and 

 failures are often most efficient instructors. 



Plants at this season of the year must have 

 a sufficient supply of water both at the roots 

 and in the atmosphere, and every induce- 

 ment must be given them to make clean, 

 strong growths. Shading must have careful 

 attention, for the sun's power will soon scald 

 the plants if they are left unprotected.
