66 CULTIVATION. 



and supported by intermediate slender props, if 

 necessary, serve to tie the stems to, with green-

When the beauty of the flowers is over, and 

 the greater number have lost their petals, the 

 awning and frame, if it be a moveable one, 

 should be taken away, the stoppers put on the 

 trunks, and the hoops again fixed in their places 

 to allow of occasional covering against excessive 

 rain. All the seed-vessels should be cut off as 

 soon as the petals drop ; because, as seeds are not 

 wanted from the fine flowers, and as this part of 

 the plant exacts a considerable portion of the 

 vigour of the system, it is only a waste of it, if 

 expended on an unnecesary production. It is 

 perfectly consistent with physiological facts, that 

 this dismemberment should have the effect al- 

 leged. It has been already shewn, that there 

 is an intimate connection between the oviparous 

 and viviparous organization of bulbous-rooted 

 plants — a reciprocity of action, balancing the 

 crescive powers of either. From the moment 

 the seed-vessel is broken off, the viviparous prin-
