situation, which will be a means of preserving it, 

 and also tend to forward the blow, as it is so late : 

 All plants that produce their flowers towards the end 

 of autumn, (however hardy) should have a favour- 

 able aspect, as to sun, lest winter overtake them be- 

 fore they can gratify us with their show. 



Poppy, allow the eastern sort a light dry soil. . 

 Reed, Portugal, is curious for its lofty and ample 

 growth, but rarely flowers with us. It attains to 

 ten or twelve feet high, and its stems are strong 

 enough for walking-sticks. The 'variegated sorts 

 come only to half the size, and more frequently 

 flowers. 



Rhubarb, the common serves for show^ and the 

 ribs of the leaves for tarts ; but the Chinese prin-

 of the root : The Chinese is deemed the true officinal 

 rhubarb. 



Rocket , (sometimes called dames violet, and queens 

 gillifloicer) the single is raised from seed, and the 

 double from rooted slips and cuttings. The double 

 is rather uncertain in continuance, and requires some 

 attention. Cut the stems down as soon as off their 

 principal show of flowering, which is a means to 

 help them to get strong and en crease at root ; and 

 it is from offsets formed in the present year, the. 4 " 

 they flower in the next. If weak, or small roots 

 are planted, they should not be suffered to blow the. 

 first year. To propagate by cuttings, do it when 

 the stems are about eight or nine inches long, (i. e. 

 before the flowering) making each into two ; and 

 plant them a little mpre than half way deep, in an 

 east border, in gjood fresh imdunged soil. Keep 

 them cool by occasional watering, and if the cuttings 

 attempt to flower, be ?ure to nip the buds off. Cut- 

 tings of stems that have flowered, will sometimes 

 grow, but they make weak plants: A hand-glass
